International Classification:

H04L 29/14

US Classification:

370216, 370242

Abstract:

A method of handling a collision event between a first and second transmission includes detecting a collision event between the first and second transmissions while processing the first transmission at a receiver. The method further includes halting decoding of the first transmission in response to detecting the collision, adjusting receive parameters to receive the second transmission, and detecting a preamble portion of the second transmission using the adjusted receive parameters.

US Classification:

375324, 375340

Abstract:

A receiver circuit includes an asynchronous demodulator having a demodulator input to receive a first signal and a demodulator output configured to provide a demodulated signal. The receiver circuit further includes a circuit, a multiplexer, and a synchronous demodulator. The modulator circuit includes a modulator input coupled to the demodulator output and includes a modulator output. The modulator re-modulates the demodulated signal to produce a second signal and provides the second signal to the modulator output. The multiplexer includes a first input to receive the first signal, a second input coupled to the modulator output to receive the second signal, a control input to a receive a select signal, and a multiplexer output. The synchronous demodulator includes an input coupled to the multiplexer output and an output to provide a demodulated output signal corresponding to a selected one of the first signal and the second signal.

US Classification:

375344

Abstract:

A method an apparatus for performing automatic frequency compensation (or control) is disclosed. A method and apparatus for performing automatic frequency compensation (or control) is disclosed. In one embodiment, a method includes a radio receiver receiving a radio signal and detecting a preamble in the radio signal. The method further includes freezing an automatic frequency compensation (AFC) loop responsive to detecting the preamble. A clock source of the AFC loop may be switched from a first clock signal to a second clock signal. The method further includes subsequently unfreezing the AFC loop.

Abstract:

Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.
