20130064114, Mar 14, 2013

Filed:

Jul 31, 2012

Appl. No.:

13/562907

Inventors:

Shyamnath Gollakota - Seattle WA, US
Dina Katabi - Cambridge MA, US
Ching-Ju Lin - Taipei, TW

International Classification:

H04W 24/00

US Classification:

370252

Abstract:

A number of techniques, which may be used together, provide distributed coordination of multiple stations so that concurrent transmissions and increased throughput are achieved on a shared radio medium. Each of the techniques provides a separate innovation that can be used alone or in combination with one or more of the other techniques.

US Classification:

375219, 375350, 375347

Abstract:

In one aspect, a method for mitigating an effect of an interfering radio signal at a multiple antenna receiver includes forming an estimate of a relationship of the interfering signal among signals received from the multiple antennas. In general, the interfering signal does not share the same communication technology as a desired signal. The signals received from the multiple antennas filtered and combined according to the estimate of the relationship of the interfering channels to reduce an effect of the interfering signal. Desired data present in the desired signal represented in the filtered and combined signals is decoded and the estimate of the relationship of the interfering signals is updated according to the decoding of the desired signal.

Abstract:

An aerial robot system may include an aerial robot having an airframe, a piezo actuator, a wing connected to the piezo actuator, and a photovoltaic cell. The system may further include a laser source configured to emit a laser beam oriented toward the photovoltaic cell for conversion by the photovoltaic cell into electrical energy. The aerial robot may further include a boost converter connected to the photovoltaic cell and configured to raise a voltage level of the electrical energy, and a signal generator connected to the boost converter and configured to generate an alternating signal. The piezo actuator is connected to the signal generator to move according to the alternating signal to cause the wing to move in a flapping motion to generate aerodynamic force that moves the robot. Methods for manufacturing aerial robots and corresponding electronics are also disclosed herein.
