Welcome back, Dr Gregory Charvat!

  • List of past appearances
    • #115
    • #179
    • #214
    • Greg was an easy hire as he's literally the "guy who wrote the book" on the subject, "Small and Short-Range Radar Systems"
    • He is currently the CTO of Humatics
    • Greg got started with project based learning - coffee can radar
    • He returned and did a stint as a visiting professor with Ramesh Raskar. They developed a camera that allows you to watch microwaves propagate
    • Fields and waves vs optics people
    • Optics make some approximations that EM people can't
    • Phase coherent processing
    • Butterfly Network was a company that developed an Ultrasound module on a chip
    • Jonathan Rothberg
    • They first developed an ultrasound tomography (similar to a CT scan) but the cost of goods was too high.
    • MEMS based sensors, instead of the traditional way of making ultrasound transducers with high frequency quartz.
    • Lots of analog parts onto the chip, the hard part was making them manufacturable.
    • Greg moved on when funding was secured
    • He then went to Hyperfine, another company founded by Jonathan Rothberg but still in stealth mode.
    • Built the first machine in 100 days
    • Built the next in 4-5 months
    • Greg is learning how to hire people
    • It costs more to over-analyze than to just start building (sometimes).
    • Greg wants to take back the term "Technology"
    • You should do a tour in defence because the unlimited budgets leads to cutting edge work.
    • Greg moved onto his current role as CTO of Humatics
    • David Mindell was a professor at MIT. He also wrote a book called Digital Apollo about the flight computer.
    • The Humatics system is a short range, super high precision GPS using microwave transceivers.
    • "That should be a piece of cake"
    • David worked for Bob Ballard, who is known for discovering the Titanic
    • ALVIN
    • HDDG talk about deep water by Nic Bingham
    • Center for marine robotics conference
    • You can see what they see at the control center live via Nautilus Live
    • GPS won't penetrate the water
    • Acoustic based navigation system
    • Perfect recreation of the titanic
    • Gary Cohen does business stuff, James Kinsey is the robotics person
    • Ultrawideband company for sale (Time Domain). Didn't buy the company right away (they did later)
    • Demo'd it at MARS - Machine and Robotics Symposium
    • Kiva Robotics told Jeff Bezos about the demo
    • Build proto in 4 months
    • It is centimeter accurate precision out to 4 nines (99.9999% of the time). It has a coverage area of 500m.
    • SLAM
    • The problem is that things change in a manufacturing scenarios
    • Currently there are humans in the loop
    • The robot is pinned to a line, which is an absolute system
    • For the forthcoming millimeter precision device, it will cover 10 m total
    • This will be used for "virtual fixturing" or said another way, "Where does stuff live in the real world?"
    • Time of flight uses impulses
    • Startups as a career path
    • Interested in learning more and/or joining their the teams discussed here?
      • Humatics
      • Hyperfine
      • Butterfly Network
        • ...more
