Getting these clients would require abandoning the corporate’s mechanical inertial-sensor methods in favor of a brand new, unproven quartz know-how, miniaturizing the quartz sensors, and turning a producer of tens of 1000’s of pricy sensors a yr right into a producer of thousands and thousands of cheaper ones.
Madni led an all-hands push to make that occur—and succeeded past what anybody may have imagined with
the GyroChip. This cheap inertial-measurement sensor was the primary such machine to be included into vehicles, enabling digital stability-control (ESC) methods to detect skidding and function the brakes to forestall rollover accidents. In response to the U.S. Nationwide Freeway Visitors Security Administration, within the five-year interval spanning 2011 to 2015, with ESCs being constructed into all new vehicles, the methods saved 7,000 lives in the US alone.
The machine went on to function the center of stability-control methods in numerous industrial and personal plane and U.S. missile steering methods, too. It even traveled to Mars as a part of the
Pathfinder Sojourner rover.

For pioneering the GyroChip, and for different contributions in know-how growth and analysis management, Madni obtained
the 2022 IEEE Medal of Honor.
Engineering wasn’t Madni’s first selection of career. He needed to be a nice artist—a painter. However his household’s financial state of affairs in Mumbai, India (then Bombay) within the Nineteen Fifties and Nineteen Sixties steered him to engineering—particularly electronics, due to his curiosity in latest improvements embodied within the pocket-size transistor radio. In 1966 he moved to the US to review electronics on the RCA Institutes in New York Metropolis, a college created within the early 1900s to coach wi-fi operators and technicians.
“I needed to be an engineer who would invent issues,” Madni says, “one who would do issues that will finally have an effect on humanity. As a result of if I couldn’t have an effect on humanity, I felt that I’d have an unfulfilling profession.”
After two years finishing the electronics know-how program on the RCA Institutes, Madni went on to
the College of California, Los Angeles (UCLA), receiving a B.S. in electrical engineering in 1969. He continued on to a grasp’s and a Ph.D., utilizing digital sign processing together with frequency-domain reflectometry to research telecommunications methods for his dissertation analysis. Whereas learning, he additionally labored variously at Pacific States College as an teacher, at Beverly Hills retailer David Orgell in stock administration, and at Pertec as an engineer designing laptop peripherals.
Then, in 1975, newly engaged and on the insistence of a former classmate, he utilized for a job in Systron Donner’s microwave division.
Madni’s began at Systron Donner by designing the world’s first spectrum analyzer with digital storage. He had by no means truly used a spectrum analyzer earlier than—these have been very costly devices on the time—however he knew sufficient in regards to the principle to speak himself into the job. He then spent six months working in testing, selecting up sensible expertise with the devices earlier than making an attempt to revamp one.
The undertaking took two years and, Madni experiences, led to a few important patents that began his climb “to greater and higher issues.” It additionally taught him, he says, an appreciation for the distinction between “what it’s to have theoretical data and what it’s to commercialize know-how that may be useful to others.”
He went on to develop quite a few RF and microwave methods and instrumentation for the U.S. army, together with an analyzer for communications strains and hooked up antennas constructed for the Navy, which turned the idea for his doctoral analysis.
Although he moved shortly into the administration ranks, finally climbing to chairman, president, and CEO of Systron Donner, former colleagues say he by no means solely left the lab behind. His technical mark was on each undertaking he turned concerned in, together with the groundbreaking work that led to the GyroChip.
Earlier than we discuss in regards to the little quartz sensor that turned the center of the GyroChip, right here’s somewhat background on the inertial-measurement models of the Nineteen Nineties. An IMU measures a number of properties of an object: its particular pressure (the acceleration that’s not attributable to gravity); its angular charge of rotation round an axis; and, generally, its orientation in three-dimensional house.
The GyroChip enabled digital stability-control methods in vehicles to detect skidding and prevented numerous rollover accidents.
Peter Adams
Within the early Nineteen Nineties, the everyday IMU used mechanical gyroscopes for angular-rate sensing. A package deal with three extremely correct spinning mass gyroscopes was in regards to the measurement of a toaster oven and weighed a couple of kilogram. Variations that used ring-laser gyroscopes or fiber-optic gyroscopes have been considerably smaller, however all high-accuracy optical and mechanical gyros of the time price 1000’s of {dollars}.
In order that was the IMU in 1990, when Systron Donner offered its defense-electronics companies to BEI Applied sciences, a publicly traded spinoff of BEI Electronics, itself a by-product of the venerable Baldwin Piano Co. The machine was massive, heavy, costly, and held transferring mechanical components that suffered from put on and tear, affecting reliability.
Shortly earlier than the sale, Systron Donner had licensed a patent for a totally totally different kind of charge sensor from a gaggle of U.S. inventors. It was little greater than a paper design on the time, Madni says, however the firm had began investing a few of its R&D finances in implementing the know-how.
The design centered on a tiny, dual-ended vibrating tuning fork carved out of quartz utilizing commonplace silicon-wafer-processing methods. The tines of the fork can be deflected by the Coriolis impact, the inertial pressure appearing on an object because it resists being pulled from its airplane of rotation. As a result of quartz has piezoelectric properties, modifications in forces appearing upon it trigger modifications in electrical cost. These modifications might be transformed into measurements of angular velocity.
The undertaking continued after Systron Donner’s divisions turned a part of BEI, and within the early Nineteen Nineties BEI was manufacturing some 10,000 quartz gyroscopic sensors yearly for a categorized protection undertaking. However with the autumn of the Soviet Union and ensuing fast contraction of the U.S. protection trade, Madni frightened that there can be no extra clients—at the least for a very long time—for these tiny new sensors and even for the normal mechanical sensors that have been the primary a part of the division’s enterprise.
“We had two choices,” Madni remembers. “We stick out within the sands and peacefully die, which might be a disgrace, as a result of no one else has this know-how. Or we discover some other place we are able to use it.”
“If I couldn’t have an effect on humanity, I felt that I’d have an unfulfilling profession.”
The hunt was on. Madni says he and members of his analysis and advertising groups went to each sensors convention they may discover, speaking to anybody who used inertial sensors, no matter whether or not the purposes have been industrial, industrial, or house. They confirmed the quartz angular-rate sensors the corporate had developed, touting their value, precision, and reliability, and laid out a path wherein the gadgets turned smaller and cheaper in only a few years. NASA was —and finally used the gadgets within the Mars Pathfinder Sojourner rover and the methods that allowed astronauts to maneuver about in house untethered. Boeing and different plane and avionics-system producers started adopting the gadgets.
However the automotive trade clearly represented the largest potential market. Within the late Eighties, automotive corporations had begun introducing primary traction-control methods of their high-end automobiles. These methods monitored steering-wheel place, throttle place, and particular person wheel speeds, and will modify engine pace and braking after they detected an issue, similar to one wheel turning sooner than one other. They couldn’t, nevertheless, detect when the course of a automotive’s activate the highway didn’t match the flip of the steering wheel, a key indicator of an unstable skid that might flip right into a rollover.
This quartz tuning fork responds to inertial forces and varieties the center of the GyroChip.

The trade was conscious this was a deficiency, and that rollover accidents have been a big reason for deaths from auto accidents. Automotive-electronics suppliers like
Bosch have been working to develop small, dependable angular-rate sensors, largely out of silicon, to enhance traction management and rollover prevention, however none have been prepared for prime time.
Madni thought this was a market BEI may win. In partnership with
Continental Teves of Frankfurt, Germany, BEI got down to cut back the scale and value of the quartz gadgets and manufacture them in portions unparalleled within the protection trade, planning to ramp as much as thousands and thousands yearly.
This main pivot—from protection to some of the aggressive mass-market industries—would require massive modifications for the corporate and for its engineers. Madni took the leap.
“I advised the fellows, ‘We’re going to need to miniaturize it. We’re going to need to carry the worth down—from $1,200 to $1,800 per axis to $100, then to $50, after which to $25. We’re going to need to promote it in lots of of 1000’s of models a month after which one million and extra a month.’”
To do all that, he knew that the design for a quartz-based charge sensor couldn’t have one additional part, he says. And that the manufacturing, provide chain, and even gross sales administration needed to be modified dramatically.
“I advised the engineers that we are able to’t have something in there apart from what is completely wanted,” Madni remembers. “And a few balked—too used to engaged on complicated designs, they weren’t focused on doing a easy design. I attempted to elucidate to them that what I used to be asking them to do was
tougher than the complicated issues they’ve executed,” he says. However he nonetheless misplaced some high-level design engineers.
“The board of administrators requested me what I used to be doing, [saying] that these have been a few of our greatest individuals. I advised them that it wasn’t a query of the most effective individuals; if individuals are not going to adapt to the present wants, what good do they do?”
Peter Adams
Others have been keen to adapt, and he despatched a few of these engineers to go to watch producers in Switzerland to find out about dealing with quartz; the watch trade had been utilizing the fabric for many years. And he provided others coaching by specialists within the automotive trade, to find out about its operations and necessities.
The modifications wanted weren’t straightforward, Madni remembers. “Now we have a variety of scars on our again. We went by way of a hell of a course of. However throughout my tenure, BEI turned the world’s largest provider of sensors for automotive stability and rollover prevention.”
Within the late Nineteen Nineties, Madni says, the marketplace for digital stability-control methods exploded, on account of an incident in 1997. An automotive journalist, testing a brand new Mercedes on a check observe, was performing the so-called elchtest, also known as the “elk check”: He swerved at regular pace, desiring to simulate avoiding a moose crossing the highway, and the automotive rolled over. Mercedes and rivals responded to the unhealthy publicity by embracing stability-control methods, and GyroChip demand skyrocketed.
Because of the cope with Continental Teves, BEI held a big piece of the automotive market for a few years. BEI wasn’t the one sport on the town at that time—Germany’s Bosch
had begun producing silicon-based MEMS charge sensors in 1998—however the California firm was the one producer utilizing quartz sensors, which on the time carried out higher than silicon. At this time, most producers of automotive-grade charge sensors use silicon, for that know-how has matured and such sensors are cheaper to supply.
Whereas manufacturing for the auto market ramped up, Madni continued to search for different markets. He discovered one other massive one within the plane trade.
The Boeing 737 within the early and mid-’90s had been concerned in a
sequence of crashes and incidents that stemmed from sudden rudder motion. Among the failures have been traced to the plane’s energy management unit, which included yaw-damping know-how. Whereas the yaw sensors weren’t particularly implicated, the corporate did want to revamp its PCUs. Madni and BEI satisfied Boeing to make use of BEI’s quartz sensors in all of its 737s going ahead, in addition to retrofitting current plane with the gadgets. Producers of plane for personal aviation quickly embraced the sensor as nicely. And finally the protection enterprise got here again.
At this time, digital angular-rate sensors are in nearly each car—land, air, or sea. And Madni’s effort to miniaturize them and cut back their price blazed the path.
By 2005, BEI’s portfolio of applied sciences had made it a pretty goal for acquisition. Moreover the speed sensors, it had earned approval for its growth of the unprecedentedly correct pointing system created for the
Hubble Area Telescope. The sensors and management group had expanded into BEI Sensors & Methods Co., of which Madni was CEO and CTO.
“We weren’t in search of a purchaser; we have been progressing extraordinarily nicely and trying to nonetheless develop. However a number of individuals needed to purchase us, and one, Schneider Electrical, was relentless. They wouldn’t hand over, and we needed to current the deal to the board.”
The sale went by way of in mid-2005 and, after a quick transition interval and turning down a management place with
Schneider Electrical, Madni formally retired in 2006.
Whereas Madni says he’s been retired since 2006, he truly retired solely from trade, crossing over right into a busy life in academia. He has served as an honorary professor at six universities, together with the Technical College of Crete, the College of Texas at San Antonio, and the College of Waikato, in New Zealand. In 2011, he joined the school of UCLA’s electrical and computer-engineering division as a distinguished scientist and distinguished adjunct professor and considers that his residence establishment. He’s on campus weekly to satisfy together with his advisees, who’re working in sensing, sign processing, AI for sensor design, and ultrawideband high-speed instrumentation. Madni has suggested 25 graduate college students thus far.
One in all his former UCLA college students, Cejo Ok. Lonappan, now principal methods engineer at
SILC Applied sciences, says Madni cares rather a lot in regards to the impression of what his advisees are doing, asking them to write down an govt abstract of each analysis undertaking that goes past the know-how to speak in regards to the greater image.
“Many occasions in educational analysis, it’s straightforward to get misplaced in particulars, in minor issues that appear spectacular to the individual doing the analysis,” Lonappan says. However Madni “cares rather a lot in regards to the impression of what we’re doing past the engineering and scientific group—the purposes, the brand new frontiers it opens.”
S.Ok. Ramesh, a professor and former dean {of electrical} engineering and laptop science at
California State College, Northridge, has additionally seen Madni the advisor in motion.
“For him,” Ramesh says, “it’s not nearly engineering. It’s about engineering the longer term, exhibiting the best way to make a distinction in individuals’s lives. And he’s not discouraged by challenges.”
“We had a gaggle of scholars who needed to take a headset utilized in gaming and use it to create a brain-control interface for wheelchair customers,” Ramesh says. “We spoke to a neurologist, and he laughed at us, stated you couldn’t try this, to watch mind waves with a headset and instantaneously switch that to a movement command. However Prof. Madni checked out it as how can we resolve the issue, and even when we are able to’t resolve it, alongside the way in which we are going to be taught one thing by making an attempt.”
Says Yannis Phillis, a professor on the
Technical College of Crete: “This man is aware of rather a lot about engineering, however he has a variety of pursuits. After we met on Crete for the primary time, for instance, I danced a solo Zeibekiko; it has roots from historic Greece. He requested me questions left and proper about it, why this, why that. He’s inquisitive about society, about human habits, in regards to the atmosphere—and, broadly talking, the survival of our civilization.”
Madni went into engineering hoping to have an effect on humanity together with his work. He’s happy that, in at the least some methods, he has executed so.
“The house purposes have enhanced the understanding of our universe, and I used to be lucky to play part of that,” he says. “My contributions [to automotive safety] in their very own humble manner have been accountable for saving thousands and thousands of lives world wide. And my applied sciences have performed a task within the protection and safety of our nation. It’s been essentially the most gratifying profession.”
