US Patent 7,039,213
More than 1 gap speaker design for high BL linearity and increased range of motion. Low THD and wide bandwidth are side benefits.
US Patent 7,873,180
A method of building a zero - or even negative - inductance loudspeaker driver with high stroke and low distortion.
Invented for Event Electronics
US Patent 8.368.271
A means of creating a high-energy storage, passively stabilized magnetically suspended flywheel storage system.
Invented for Xinova
US Patent 8,867,764
A system to provide DIY/at home hearing aid fitting with minimal effort. No need to ever see a hearing health pro.
Invented for Aurasen
US Patent 8,965,033
A means of using variable-speed of sound material in front of transducers to correct for time alignment.
Invented for SONOS
US Patent 9,131,308
Nonlinear ear plugs which corrected for Fletcher Munson losses in musical situations. These became the popular DUBS plugs.
Invented for Doppler Labs
The highest stroke subwoofer while in production, the same model held multiple world SPL records and multiple world sound quality championships, proving that one woofer CAN do it all. Exceptionally high stroke with extremely wide bandwidth and low distortion.
SONOS' top-selling speaker, this little powerhouse has a massive sound for being so little. I provided the basic acoustic architecture and designed the woofer and tweeter, as well as production-level processes for this - and many other - SONOS products.
In the mid 1990s, we changed what a research SONAR system was. Moved to PCs, wireless networking, machine learning, automatic fish tracking, and unparalleled resolution and capabilities. The DT series are still in production today, still setting the benchmark.
The Microsoft RoundTable became the Polycom CX5000 - the best video conferencing system on the market. I designed the transducers, all the physical acoustics (including microphones), mechanical design support, and manufacturing/supplier support.
This powerhouse of a two way studio monitor won FutureMusic UK's Monitor of the Decade award. A massively powerful 8" with midrange articulation better than any dome mid, a beryllium copper dome, and huge power. I designed the transducers and worked on the physical acoustics.
Love or hate the ID, these sound great. A true reference planar headphone, built in discrete amplifier, and great audio isolation make these a reference-level headphone. I did several 'phones for Blue (as well as mics), but this is the one I'm most proud to claim as my own.
I worked with the client and their factory to install this high-volume transducer line, capable of over 40,000 TV speakers a day for one of the largest TV brands in the world.
Magnets are more than just elements. It's the process of grinding, sifting, and blending that makes or breaks a magnet. I reworked their process to increase yield by 15%.
This in-ear headphone was designed with molded in features to make it impossible to assemble incorrectly. Each part can only be inserted one way, guaranteeing quality.
I reside in Port Hueneme, California, about 1 hour from Los Angeles and 30 minutes from Santa Barbara, right next to Ventura and Oxnard.
I travel quite a bit for work. Being mobile allows me to service customers all around the world. E-mail is the best way to get in touch with me, and I can usually respond within 48 business hours.
This is my mailing address; it can receive all packages and correspondence. Samples and components should be sent to this address unless otherwise instructed.
