Colorado State University For computer pioneer Craig Partridge , pushing the envelope on interesting challenges has been his modus operandi. It’s what led him to make key contributions to the early Internet. Today he’s working on getting a better understanding of traffic flows in VPNs . In addition, he is trying to figure out what causes high rates of packet errors, which often result in bad file transfers, and how to fix them. Although his bachelor’s degree from Harvard was in history, the computer electives he took convinced him he had both the aptitude and interest for a career in computing. And he was right. He focused on networking concepts and technologies while working at the ARPAnet and Internet pioneering firm Bolt Beranek & Newman (BBN), now Raytheon BBN Technologies . There, the IEEE Fellow collaborated with TCP/IP developer Phil Karn on TCP message round-trip time estimation. Partridge also led the team that designed and built the world’s first high-speed router. “It was 1983, and BBN needed an additional person who could write TCP/IP code for the BSD [Berkeley Software Distribution] Unix operating system,” he says. “BBN had folks who wrote most of the original code, and they taught me what networking and TCP/IP was. That was something no grad school at the time could teach me. “A lot of what I worked on 30 or more years ago is still used today,” Partridge notes proudly. “More generally, a lot of the Internet tech used today is entirely or almost entirely recognizable from what was created back then. That’s a very pleasant feeling.” Partridge is an Internet Hall of Fame inductee for his work in designing how email is routed using domain names. While working at BBN, he went on to earn a master’s and Ph.D. in computer science, both from Harvard. By 2018 Partridge was chief scientist for networking research at BBN, but he decided he didn’t want his tenure there to be the last chapter of his career. Later that year he joined Colorado State University in Fort Collins, as chair of its department of computer science. Partridge says it’s not uncommon for engineers to move from industry to academia later in their careers. They often want to “give back” by becoming professors, deans, or department chairs. One of his assignments at CSU was to reexamine the school’s computer science curriculum. Among other improvements, the faculty now teaches courses in machine learning earlier. Virtual reality and virtual spaces courses were created, and the math requirements were revamped. Efforts to increase the number of women in computing Partridge says during the mid-1980s he became aware of some of the challenges that women face in computing careers. “At BBN, at one point, my project leader, my boss, and my boss’s vice president were all women,” he recalls. “A number of women in computing at the time commented to me how rare that was. It opened my eyes. “So in 1987 when I was looking to shift from industry to academia, I made it clear in my interviews at various universities that one of my goals was to look for ways to leverage what I had seen and learned, to help bring more women into computing.” “Our focus at Colorado State is on the students already on campus. We encourage them to apply to computer science. We are also improving our curriculum by following the BRAID (Building, Recruiting, and Inclusion for Diversity) principles.” He says this effort has included figuring out how to make the introductory courses speak to a wider variety of students by covering the same material but using different examples and different presentations that relate to how they could use computing to solve problems that interest them. “We are trying to get them to understand that just because you can create something new doesn’t mean that society wants it,” he says. “You must create it in a way that is more likely to benefit society.” In the four years since introducing these changes, Partridge says about half the students taking the introductory courses are women, and the number of women majoring in computing has nearly doubled, from 12 percent to more than 20 percent. Conducting research in an academic setting Partridge also has continued to conduct research, which he finds very different from how he did research at BBN. “You are trying to do research while trying to teach the students,” he says. “You could often do the research faster yourself, but then the student wouldn’t learn. By comparison, in industry I knew I had a team I could give a broad description to and get the right thing the first time. With students, by the time they get good at it, they are graduating.” In 2011, in response to a decade-old request from IEEE Spectrum columnist and IEEE Fellow Robert Lucky for a list of open research questions in networking, Partridge published “Forty Data Communications Research Questions” in ACM ’s Computer Communication Review . Many of these questions remain as concerns. For example, one of his graduate students studied packet errors and discovered that checksums, which are used to detect corruption in the header of IPv4 packets, are bad at detecting certain kinds of errors that are likely to occur over asynchronous transfer mode. “We are using that kind of experience again today to find the next generation of packet errors in data centers,” Partridge says. He would like today’s engineers to pay more attention to edge computing, smart home infrastructure, vehicle safety systems, and walled-garden social networks, such as Instagram and Twitter. He says walled gardens are “social networks where people don't want to connect to people who don't want to connect with those who think differently.” One challenge in preparing students for the world they will be working in, he says, “is getting them to understand that just because you can create something new doesn’t mean that society wants it.” This article appears in the November 2022 print issue as “Craig Partridge.” From Your Site Articles The Conversation (0) Vertical In 1992, Asad M. Madni sat at the helm of BEI Sensors and Controls, overseeing a product line that included a variety of sensor and inertial-navigation devices, but its customers were less varied—mainly, the aerospace and defense electronics industries. And he had a problem. The Cold War had ended, crashing the U.S. defense industry. And business wasn’t going to come back anytime soon. BEI needed to identify and capture new customers—and quickly. Getting those customers would require abandoning the company’s mechanical inertial-sensor systems in favor of a new, unproven quartz technology, miniaturizing the quartz sensors, and turning a manufacturer of tens of thousands of expensive sensors a year into a manufacturer of millions of cheaper ones. Madni led an all-hands push to make that happen—and succeeded beyond what anyone could have imagined with the GyroChip . This inexpensive inertial-measurement sensor was the first such device to be incorporated into automobiles, enabling electronic stability-control (ESC) systems to detect skidding and operate the brakes to prevent rollover accidents. According to the U.S. National Highway Traffic Safety Administration, in the five-year period spanning 2011 to 2015, with ESCs being built into all new cars, the systems saved 7,000 lives in the United States alone. The device went on to serve as the heart of stability-control systems in countless commercial and private aircraft and U.S. missile guidance systems, too. It even traveled to Mars as part of the Pathfinder Sojourner rover . Vital Statistics Name: Asad M.

Engineering wasn’t Madni’s first choice of profession. He wanted to be a fine artist—a painter. But his family’s economic situation in Mumbai, India (then Bombay) in the 1950s and 1960s steered him to engineering—specifically electronics, thanks to his interest in recent innovations embodied in the pocket-size transistor radio. In 1966 he moved to the United States to study electronics at the RCA Institutes in New York City, a school created in the early 1900s to train wireless operators and technicians. “I wanted to be an engineer who would invent things,” Madni says, “one who would do things that would eventually affect humanity. Because if I couldn’t affect humanity, I felt that I would have an unfulfilling career.” After two years completing the electronics technology program at the RCA Institutes, Madni went on to the University of California, Los Angeles (UCLA) , receiving a B.S. in electrical engineering in 1969. He continued on to a master’s and a Ph.D., using digital signal processing along with frequency-domain reflectometry to analyze telecommunications systems for his dissertation research. While studying, he also worked variously at Pacific States University as an instructor, at Beverly Hills retailer David Orgell in inventory management, and at Pertec as an engineer designing computer peripherals. Then, in 1975, newly engaged and at the insistence of a former classmate, he applied for a job in Systron Donner’s microwave division. Madni’s started at Systron Donner by designing the world’s first spectrum analyzer with digital storage. He had never actually used a spectrum analyzer before—these were very expensive instruments at the time—but he knew enough about the theory to talk himself into the job. He then spent six months working in testing, picking up practical experience with the instruments before attempting to redesign one. The project took two years and, Madni reports, led to three significant patents that started his climb “to bigger and better things.” It also taught him, he says, an appreciation for the difference between “what it is to have theoretical knowledge and what it is to commercialize technology that can be helpful to others.” He went on to develop numerous RF and microwave systems and instrumentation for the U.S. military, including an analyzer for communications lines and attached antennas built for the Navy, which became the basis for his doctoral research. Though he moved quickly into the management ranks, eventually climbing to chairman, president, and CEO of Systron Donner, former colleagues say he never entirely left the lab behind. His technical mark was on every project he became involved in, including the groundbreaking work that led to the GyroChip. Before we talkabout the little quartz sensor that became the heart of the GyroChip, here’s a little background on the inertial-measurement units of the 1990s. An IMU measures several properties of an object: its specific force (the acceleration that’s not due to gravity); its angular rate of rotation around an axis; and, sometimes, its orientation in three-dimensional space. The GyroChip enabled electronic stability-control systems in automobiles to detect skidding and prevented countless rollover accidents. Peter Adams In the early 1990s, the typical IMU used mechanical gyroscopes for angular-rate sensing. A package with three highly accurate spinning mass gyroscopes was about the size of a toaster oven and weighed about a kilogram. Versions that used ring-laser gyroscopes or fiber-optic gyroscopes were somewhat smaller, but all high-accuracy optical and mechanical gyros of the time cost thousands of dollars. So that was the IMU in 1990, when Systron Donner sold its defense-electronics businesses to BEI Technologies, a publicly traded spinoff of BEI Electronics, itself a spinoff of the venerable Baldwin Piano Co. The device was big, heavy, expensive, and held moving mechanical parts that suffered from wear and tear, affecting reliability. Shortly before the sale, Systron Donner had licensed a patent for a completely different type of rate sensor from a group of U.S. inventors. It was little more than a paper design at the time, Madni says, but the company had started investing some of its R&D budget in implementing the technology. The design centered on a tiny, dual-ended vibrating tuning fork carved out of quartz using standard silicon-wafer-processing techniques. The tines of the fork would be deflected by the Coriolis effect, the inertial force acting on an object as it resists being pulled from its plane of rotation. Because quartz has piezoelectric properties, changes in forces acting upon it cause changes in electric charge. These changes could be converted into measurements of angular velocity. The project continued after Systron Donner’s divisions became part of BEI, and in the early 1990s BEI was manufacturing some 10,000 quartz gyroscopic sensors annually for a classified defense project. But with the fall of the Soviet Union and ensuing rapid contraction of the U.S. defense industry, Madni worried that there would be no more customers—at least for a long time—for these tiny new sensors or even for the traditional mechanical sensors that were the main part of the division’s business. “We had two options,” Madni recalls. “We stick out in the sands and peacefully die, which would be a shame, because nobody else has this technology. Or we find somewhere else we can use it.” “If I couldn’t affect humanity, I felt that I would have an unfulfilling career.” The hunt was on. Madni says he and members of his research and marketing teams went to every sensors conference they could find, talking to anyone who used inertial sensors, regardless of whether the applications were industrial, commercial, or space. They showed the quartz angular-rate sensors the company had developed, touting their price, precision, and reliability, and laid out a path in which the devices became smaller and cheaper in just a few years. NASA was interested—and eventually used the devices in the Mars Pathfinder Sojourner rover and the systems that allowed astronauts to move about in space untethered. Boeing and other aircraft and avionics-system manufacturers began adopting the devices. But the automotive industry clearly represented the biggest potential market. In the late 1980s, car companies had begun introducing basic traction-control systems in their high-end vehicles. These systems monitored steering-wheel position, throttle position, and individual wheel speeds, and could adjust engine speed and braking when they detected a problem, such as one wheel turning faster than another. They couldn’t, however, detect when the direction of a car’s turn on the road didn’t match the turn of the steering wheel, a key indicator of an unstable skid that could turn into a rollover. This quartz tuning fork responds to inertial forces and forms the heart of the GyroChip. Peter Adams The industry was aware this was a deficiency, and that rollover accidents were a significant cause of deaths from auto accidents. Automotive-electronics suppliers like Bosch were working to develop small, reliable angular-rate sensors, mostly out of silicon, to improve traction control and rollover prevention, but none were ready for prime time. Madni thought this was a market BEI could win. In partnership with Continental Teves of Frankfurt, Germany, BEI set out to reduce the size and cost of the quartz devices and manufacture them in quantities unheard of in the defense industry, planning to ramp up to millions annually. This major pivot—from defense to one of the most competitive mass-market industries—would require big changes for the company and for its engineers. Madni took the leap. “I told the guys, ‘We are going to have to miniaturize it. We are going to have to bring the price down—from $1,200 to $1,800 per axis to $100, then to $50, and then to $25. We are going to have to sell it in hundreds of thousands of units a month and then a million and more a month.’” To do all that, he knew that the design for a quartz-based rate sensor couldn’t have one extra component, he says. And that the manufacturing, supply chain, and even sales management had to be changed dramatically. “I told the engineers that we can’t have anything in there other than what is absolutely needed,” Madni recalls. “And some balked—too used to working on complex designs, they weren’t interested in doing a simple design. I tried to explain to them that what I was asking them to do was more difficult than the complex things they’ve done,” he says. But he still lost some high-level design engineers. “The board of directors asked me what I was doing, [saying] that those were some of our best people. I told them that it wasn’t a question of the best people; if people are not going to adapt to the current needs, what good do they do?” Peter Adams Others were willing to adapt, and he sent some of those engineers to visit watch manufacturers in Switzerland to learn about handling quartz; the watch industry had been using the material for decades. And he offered others training by experts in the automotive industry, to learn about its operations and requirements. The changes needed were not easy, Madni remembers. “We have a lot of scars on our back. We went through a hell of a process. But during my tenure, BEI became the world’s largest supplier of sensors for automotive stability and rollover prevention.” In the late 1990s, Madni says, the market for electronic stability-control systems exploded, as a result of an incident in 1997 . An automotive journalist, testing a new Mercedes on a test track, was performing the so-called elchtest, often referred to as the “elk test”: He swerved at normal speed, intending to simulate avoiding a moose crossing the road, and the car rolled over. Mercedes and competitors responded to the bad publicity by embracing stability-control systems, and GyroChip demand skyrocketed. Thanks to the deal with Continental Teves, BEI held a large piece of the automotive market for many years. BEI wasn’t the only game in town at that point—Germany’s Bosch had begun producing silicon-based MEMS rate sensors in 1998—but the California company was the only manufacturer using quartz sensors, which at the time performed better than silicon. Today, most manufacturers of automotive-grade rate sensors use silicon, for that technology has matured and such sensors are cheaper to produce. While manufacturing for the auto market ramped up, Madni continued to look for other markets. He found another big one in the aircraft industry. The Boeing 737 in the early and mid-’90s had been involved in a series of crashes and incidents that stemmed from unexpected rudder movement. Some of the failures were traced to the aircraft’s power control unit, which incorporated yaw-damping technology. While the yaw sensors weren’t specifically implicated, the company did need to redesign its PCUs. Madni and BEI convinced Boeing to use BEI’s quartz sensors in all of its 737s going forward, as well as retrofitting existing aircraft with the devices. Manufacturers of aircraft for private aviation soon embraced the sensor as well. And eventually the defense business came back. Asad Madni explains a problem in electron ballistics to a classmate at the RCA Institutes in 1966 [top]. In 1977, Madni [seated, center] discusses the communications-line analyzer he developed for the U.S. Navy. Asad Madni Today, electronic angular-rate sensors are in just about every vehicle—land, air, or sea. And Madni’s effort to miniaturize them and reduce their cost blazed the trail. By 2005, BEI’s portfolio of technologies had made it an attractive target for acquisition. Besides the rate sensors, it had earned acclaim for its development of the unprecedentedly accurate pointing system created for the Hubble Space Telescope . The sensors and control group had expanded into BEI Sensors & Systems Co., of which Madni was CEO and CTO. “We weren’t looking for a buyer; we were progressing extremely well and looking to still grow. But several people wanted to buy us, and one, Schneider Electric, was relentless. They wouldn’t give up, and we had to present the deal to the board.” The sale went through in mid-2005 and, after a brief transition period and turning down a leadership position with Schneider Electric , Madni officially retired in 2006. While Madni says he’s been retired since 2006, he actually retired only from industry, crossing over into a busy life in academia. He has served as an honorary professor at six universities, including the Technical University of Crete , the University of Texas at San Antonio , and the University of Waikato , in New Zealand. In 2011, he joined the faculty of UCLA’s electrical and computer-engineering department as a distinguished scientist and distinguished adjunct professor and considers that his home institution. He is on campus weekly to meet with his advisees, who are working in sensing, signal processing, AI for sensor design, and ultrawideband high-speed instrumentation . Madni has advised 25 graduate students to date. One of his former UCLA students, Cejo K. Lonappan, now principal systems engineer at SILC Technologies , says Madni cares a lot about the impact of what his advisees are doing, asking them to write an executive summary of every research project that goes beyond the technology to talk about the bigger picture. “Many times in academic research, it is easy to get lost in details, in minor things that seem impressive to the person doing the research,” Lonappan says. But Madni “cares a lot about the impact of what we are doing beyond the engineering and scientific community—the applications, the new frontiers it opens.” S.K. Ramesh, a professor and former dean of electrical engineering and computer science at California State University, Northridge , has also seen Madni the advisor in action. “For him,” Ramesh says, “it’s not just about engineering. It’s about engineering the future, showing how to make a difference in people’s lives. And he’s not discouraged by challenges.” “We had a group of students who wanted to take a headset used in gaming and use it to create a brain-control interface for wheelchair users,” Ramesh says. “We spoke to a neurologist, and he laughed at us, said you couldn’t do that, to monitor brain waves with a headset and instantaneously transfer that to a motion command. But Prof. Madni looked at it as how do we solve the problem, and even if we can’t solve it, along the way we will learn something by trying.” Says Yannis Phillis, a professor at the Technical University of Crete : “This man knows a lot about engineering, but he has a wide range of interests. When we met on Crete for the first time, for example, I danced a solo Zeibekiko; it has roots from ancient Greece. He asked me questions left and right about it, why this, why that. He is curious about society, about human behavior, about the environment—and, broadly speaking, the survival of our civilization.” Madni went into engineering hoping to affect humanity with his work. He is satisfied that, in at least some ways, he has done so. “The space applications have enhanced the understanding of our universe, and I was fortunate to play a part of that,” he says. “My contributions [to automotive safety] in their own humble way have been responsible for saving millions of lives around the world. And my technologies have played a role in the defense and security of our nation. It’s been the most gratifying career.” From Your Site Articles

Integrated Sensors

Integrated Sensor Technologies is a company that received a SBIR Phase II grant for a project entitled: Structurally Integrated Organic Light Emitting Device-Based Sensors for Dissolved Oxygen in Water. Their project aims to develop and commercialize a novel, next-generation photoluminescence (PL)-based, palm-size and miniaturizable dissolved oxygen (DO) sensor. DO sensors are primary monitors of water quality in industrial wastewater treatment. The new sensor is based on a pioneering platform for PL-based biochemical sensors where the excitation source is a pulsed organic light emitting device (OLED) pixel array that is structurally integrated with the sensor component. The individually addressable pixels and the sensor film are fabricated on either side of the glass substrate. The photodetector is "behind" the OLED array, monitoring the PL passing between the OLED pixels. This uniquely simple structural integration enables multi-sensor fabrication on a single, compact substrate, and should therefore yield field-deployable micro-sensor arrays for simultaneous detection of various analytes. This sensor has applicability in water quality measurements in wastewater treatment, power, pulp and paper, chemical, food, beverage, brewing, and pharmaceuticals plants, fish farms, fresh water, coastlines, and the oceans. Current sensors suffer from key drawbacks that limit their utility and application. Electrochemical sensors require frequent calibration and maintenance, and are typically slow to respond. PL-based sensors are expensive due to intricate design. The proposed sensor will be reliable, require very little maintenance/calibration, and will be inexpensive, with a flexible design and size. The proposed device will be uniquely simple, initially palm-size and eventually micro-size, autonomous, fast, miserly on power consumption, and inexpensive. It will be structurally integrated and will operate in a pulsed PL-lifetime mode, eliminating the need for optical components and frequent calibration. Integrated Sensor Technologies is a company that received a SBIR Phase I grant for a project entitled: Structurally Integrated Organic Light Emitting Device-Based Sensors for Dissolved Oxygen in Water. Their project aims to develop a next-generation microsensor for dissolved oxygen (DO) in water. DO sensors are a primary tool for gauging the quality of both fresh water (rivers, lakes, reservoirs) and the oceans; for monitoring the various processes in waste water treatment plants; and, for monitoring fermentation processes in the food and beverage industries. Unfortunately, electrochemical sensors are slow (response time >1 min), short-lived (a few days), and expensive (~$500). The proposed DO sensor is based on a new platform of structurally integrated photoluminescence (PL)-based chemical and biological sensors. In this platform, the pulsed light source that excites the PL is an array of individually addressable ~100 um2 to ~1 cm2 organic light-emitting device (OLED) pixels. The small pixels will eventually enable development of microsensor arrays. The ~0.5 um-thick pixel array and ~1 um-thick sensor film will be fabricated on opposite sides of a glass or plastic substrate, or on two substrates attached back-to-back. The Si photodiode will be "behind" the OLED array, monitoring the PL passing between the OLED pixels. This uniquely simple structurally integrated platform should ultimately yield multianalyte chemical and biological microsensor arrays for a wide variety of agents. If successful the proposed device will be uniquely simple, initially palm-size and eventually microsize, autonomous, fast (~1 sec response), miserly on power consumption, and inexpensive (ultimately with an essentially disposable OLED/sensor film module). It will operate in the PL-lifetime mode, eliminating the need for frequent calibration. It will consequently replace the short-lived electrochemical sensors and the expensive PL-based DO sensors that currently serve the diverse markets listed above. The proposed development of the DO microsensor will demonstrate the viability of the new OLED-based sensor platform, leading the way towards the development of multianalyte chemical and biological microsensor arrays for gas and liquid phases. This development will enhance scientific and technological needs in the field of sensor technology by addressing current issues of sensor size, cost, analyte sampling, and field deployability.

Halogen Systems

Halogen Systems is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Development of a Total Residual Oxidant Sensor Development of a Total Residual Oxidant Sensor. The abstract given for this project is as follows: Recent efforts at improving shipboard operations have focused on desalination systems. One area in which manpower may be significantly reduced is in the monitoring chlorine residuals from hypochlorite enhanced streams that are used for periodic biofouling control flushes of microfiltration membranes. These are used for pretreatment of seawater prior to exposure to reverse osmosis membranes used for desalination. Another area of interest is the measurement of oxidant levels in potable water to ensure safe levels are maintained. Current manual methods are not an efficient use of resources. These manual methods require consumables and are not real time. Commercially available sensors are unable to survive or accurately measure levels of oxidant in the 50 to 500 ppm range. Halogen Systems proposes to adapt its Chlorine Sensor Technology Platform to provide long term measurement stability along with a level of performance necessary for monitoring the Total Residual Oxidant levels of hypochlorite enhanced seawater flushing and potable water bromine and chlorine measurement.
