Overcoming Systemic Racism Through System Engineering


Getting these prospects would require abandoning the corporate’s mechanical inertial-sensor programs in favor of a brand new, unproven quartz know-how, miniaturizing the quartz sensors, and turning a producer of tens of hundreds of pricey 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 system to be included into cars, enabling digital stability-control (ESC) programs to detect skidding and function the brakes to forestall rollover accidents. Based on 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 systems saved 7,000 lives in the US alone.

The system went on to function the guts of stability-control programs in numerous industrial and personal plane and U.S. missile steerage programs, 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 improvement and analysis management, Madni obtained
the 2022 IEEE Medal of Honor.

Engineering wasn’t Madni’s first selection of occupation. He needed to be a superb artist—a painter. However his household’s financial scenario 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 check electronics at 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 might have an unfulfilling profession.”

After two years finishing the electronics know-how program on 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 grasp’s and a Ph.D., utilizing digital sign processing together with frequency-domain reflectometry to investigate telecommunications programs 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 had 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 mission took two years and, Madni reviews, led to a few vital 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 programs and instrumentation for the U.S. army, together with an analyzer for communications traces and connected 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 totally left the lab behind. His technical mark was on each mission he turned concerned in, together with the groundbreaking work that led to the GyroChip.

Earlier than we discussabout the little quartz sensor that turned the guts 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 power (the acceleration that’s not attributable to gravity); its angular fee of rotation round an axis; and, typically, its orientation in three-dimensional area.

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 few kilogram. Variations that used ring-laser gyroscopes or fiber-optic gyroscopes had been considerably smaller, however all high-accuracy optical and mechanical gyros of the time value hundreds of {dollars}.

In order that was the IMU in 1990, when Systron Donner bought its defense-electronics companies to BEI Applied sciences, a publicly traded spinoff of BEI Electronics, itself a derivative of the venerable Baldwin Piano Co. The system was huge, heavy, costly, and held shifting 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 completely different sort of fee 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 power performing on an object because it resists being pulled from its aircraft of rotation. As a result of quartz has piezoelectric properties, modifications in forces performing upon it trigger modifications in electrical cost. These modifications could possibly be transformed into measurements of angular velocity.

The mission 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 labeled protection mission. However with the autumn of the Soviet Union and ensuing speedy contraction of the U.S. protection business, Madni nervous that there can be no extra prospects—a minimum of for a very long time—for these tiny new sensors and even for the standard mechanical sensors that had 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 person else has this know-how. Or we discover some place else we are able to use it.”

“If I couldn’t have an effect on humanity, I felt that I might have an unfulfilling profession.”

The hunt was on. Madni says he and members of his analysis and advertising and marketing groups went to each sensors convention they may discover, speaking to anybody who used inertial sensors, no matter whether or not the functions had been industrial, industrial, or area. They confirmed the quartz angular-rate sensors the corporate had developed, touting their worth, precision, and reliability, and laid out a path by which the units turned smaller and cheaper in only a few years. NASA was —and finally used the units within the Mars Pathfinder Sojourner rover and the programs that allowed astronauts to maneuver about in area untethered. Boeing and different plane and avionics-system producers started adopting the units.

However the automotive business clearly represented the largest potential market. Within the late Eighties, automobile firms had begun introducing fundamental traction-control programs of their high-end autos. These programs monitored steering-wheel place, throttle place, and particular person wheel speeds, and will modify engine pace and braking after they detected an issue, reminiscent of one wheel turning sooner than one other. They couldn’t, nevertheless, detect when the course of a automobile’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.

The business was conscious this was a deficiency, and that rollover accidents had been a major reason for deaths from auto accidents. Automotive-electronics suppliers like
Bosch had been working to develop small, dependable angular-rate sensors, principally out of silicon, to enhance traction management and rollover prevention, however none had 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 dimensions and price of the quartz units and manufacture them in portions unparalleled within the protection business, planning to ramp as much as thousands and thousands yearly.

This main pivot—from protection to one of the aggressive mass-market industries—would require huge modifications for the corporate and for its engineers. Madni took the leap.

“I advised the fellows, ‘We’re going to should miniaturize it. We’re going to should deliver the worth down—from $1,200 to $1,800 per axis to $100, then to $50, after which to $25. We’re going to should promote it in a whole lot of hundreds 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 fee 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 excited by doing a easy design. I attempted to elucidate to them that what I used to be asking them to do was
extra tough than the complicated issues they’ve accomplished,” 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 had been a few of our greatest folks. I advised them that it wasn’t a query of the perfect folks; if persons are not going to adapt to the present wants, what good do they do?”

Others had been keen to adapt, and he despatched a few of these engineers to go to watch producers in Switzerland to study dealing with quartz; the watch business had been utilizing the fabric for many years. And he provided others coaching by consultants within the automotive business, to study its operations and necessities.

The modifications wanted weren’t simple, Madni remembers. “We’ve a number 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 programs exploded, on account of an incident in 1997. An automotive journalist, testing a brand new Mercedes on a take a look at observe, was performing the so-called elchtest, also known as the “elk take a look at”: He swerved at regular pace, aspiring to simulate avoiding a moose crossing the highway, and the automobile rolled over. Mercedes and opponents responded to the dangerous publicity by embracing stability-control programs, and GyroChip demand skyrocketed.

Due to the take care of Continental Teves, BEI held a big piece of the automotive market for a few years. BEI wasn’t the one recreation on the town at that time—Germany’s Bosch
had begun producing silicon-based MEMS fee sensors in 1998—however the California firm was the one producer utilizing quartz sensors, which on the time carried out higher than silicon. At present, most producers of automotive-grade fee sensors use silicon, for that know-how has matured and such sensors are cheaper to provide.

Whereas manufacturing for the auto market ramped up, Madni continued to search for different markets. He discovered one other huge one within the plane business.

The Boeing 737 within the early and mid-’90s had been concerned in a
series of crashes and incidents that stemmed from sudden rudder motion. A few of the failures had 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 present plane with the units. Producers of plane for personal aviation quickly embraced the sensor as nicely. And finally the protection enterprise got here again.

At present, digital angular-rate sensors are in nearly each automobile—land, air, or sea. And Madni’s effort to miniaturize them and cut back their value blazed the path.

By 2005, BEI’s portfolio of applied sciences had made it a gorgeous goal for acquisition. Apart from the speed sensors, it had earned popularity of its improvement of the unprecedentedly correct pointing system created for the
Hubble Space Telescope. The sensors and management group had expanded into BEI Sensors & Methods Co., of which Madni was CEO and CTO.

“We weren’t on the lookout for a purchaser; we had been progressing extraordinarily nicely and seeking to nonetheless develop. However a number of folks 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 Electric, Madni formally retired in 2006.

Whereas Madni says he’s been retired since 2006, he truly retired solely from business, crossing over right into a busy life in academia. He has served as an honorary professor at six universities, together with 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 college of UCLA’s electrical and computer-engineering division as a distinguished scientist and distinguished adjunct professor and considers that his dwelling establishment. He’s on campus weekly to satisfy along 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 to this point.

One among his former UCLA college students, Cejo Okay. Lonappan, now principal programs engineer at
SILC Technologies, says Madni cares loads in regards to the impression of what his advisees are doing, asking them to write down an govt abstract of each analysis mission that goes past the know-how to speak in regards to the greater image.

“Many instances in educational analysis, it’s simple to get misplaced in particulars, in minor issues that appear spectacular to the particular person doing the analysis,” Lonappan says. However Madni “cares loads in regards to the impression of what we’re doing past the engineering and scientific neighborhood—the functions, the brand new frontiers it opens.”

S.Okay. Ramesh, a professor and former dean {of electrical} engineering and laptop science at
California State University, 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, displaying how you can make a distinction in folks’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 do this, to observe 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’ll be taught one thing by making an attempt.”

Says Yannis Phillis, a professor on the
Technical University of Crete: “This man is aware of loads 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 interested in society, about human habits, in regards to the setting—and, broadly talking, the survival of our civilization.”

Madni went into engineering hoping to have an effect on humanity along with his work. He’s happy that, in a minimum of some methods, he has accomplished so.

“The area functions 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 answerable for saving thousands and thousands of lives all over the world. And my applied sciences have performed a job within the protection and safety of our nation. It’s been probably the most gratifying profession.”
