Sound Amplification System Comprising A Combined Ir-Sensor/Speaker

View page
US Patent:
20100310090, Dec 9, 2010
Filed:
Jun 9, 2009
Appl. No.:
12/481395
Inventors:
Roger Davis - Petaluma CA, US
Michael Grall - Mountain View CA, US
Andrew Parker - Petaluma CA, US
Assignee:
PHONIC EAR INC. - Petaluma CA
International Classification:
H04R 27/00
US Classification:
381 82
Abstract:
A public address system including a wireless IR microphone for picking up a sound and converting it to an IR light signal including an audio signal representative of said sound and adapted for being transmitted to an IR sensor; an IR sensor including an IR photo detector for receiving said IR light signal and a first receiver for extracting said audio signal and a first transmitter transmitting it to a base station; a base station including a second receiver for receiving said audio signal from said IR sensor and a processor for processing said audio signal to provide a processed audio signal and a second transmitter transmitting it to a loud speaker; and a loud speaker unit for receiving said processed audio signal and converting it to a processed sound signal for being presented to an audience, wherein said IR sensor and loudspeaker unit are integrated into a sensor-speaker assembly.

Dual-Polarized, Dual-Band, Compact Beam Forming Network

US Patent:
20170170561, Jun 15, 2017
Filed:
Dec 14, 2015
Appl. No.:
14/968725
Inventors:
- Palo Alto CA, US
Michael Aliamus - San Jose CA, US
Behzad Tavassoli Hozouri - Sunnyvale CA, US
Robert Jones - Union City CA, US
Michael Grall - Santa Cruz CA, US
International Classification:
H01Q 5/28
H01Q 21/00
H01Q 3/36
Abstract:
A spacecraft communications payload includes a beam forming network (BFN), wherein the BFN includes a first feed waveguide and a first set of branch waveguides, each branch waveguide in the first set operating in a frequency band having a characteristic waveguide wavelength λ. A proximal portion of the first set of branch waveguides is communicatively coupled with the first feed waveguide. A distal portion of the first set of branch waveguides is communicatively coupled by way of an array of slots with a plurality of radiating elements. A separation distance between adjacent slots in the array is approximately equal to λ, and the array of slots is configured as a honeycomb-like triaxial lattice. In some implementations, a compact BFN may be configured to simultaneously operate at two different polarizations (“dual-polarized”) and/or frequency bands (“dual-band”).
