8619240, Dec 31, 2013

Filed:

Feb 14, 2011

Appl. No.:

13/026449

Inventors:

Robert A. Card - Scarborough ME, US

Assignee:

Fairchild Semiconductor Corporation - San Jose CA

International Classification:

G01C 3/08

US Classification:

356 501, 356 51

Abstract:

This document discusses among other things, methods and apparatus to conserve energy when providing proximity information. An example apparatus can include an energy emitter configured to emit a first pulse of energy, an energy sensor configured to receive reflected energy from the first pulse of energy, a control circuit including a processor, the processor configured to provide first proximity information of the apparatus with respect to an object using the reflected energy. The control circuit can be configured to control the energy emitter, to compare the first proximity information with second proximity information, and to modulate a delay between the first pulse of energy and a subsequent pulse of energy using the comparison.

Appl. No.:

13/093096

Inventors:

Robert A. Card - Scarborough ME, US

International Classification:

H04B 1/38

US Classification:

455558

Abstract:

The present application discusses, among other things, apparatus to reduce the amount of processor general purpose input or outputs consumed to interface simultaneously with multiple subscription identification modules (SIMs). In an example, an apparatus can include a controller, first and second subscriber identity module (SIM) ports configured to transmit SIM information between the controller and first and second SIMs coupled to the first and second SIM ports, and a communication controller configured to couple to a base band processor using a two-wire serial communication bus, the communication controller configured to transmit the SIM information between the controller and the base band processor.

Appl. No.:

13/098898

Inventors:

Robert A. Card - Scarborough ME, US

International Classification:

G06F 13/24

US Classification:

710260

Abstract:

This document provides apparatus and methods for providing low latency response from a processor to the interrupts collected from peripheral devices. In an example, an apparatus can collect interrupt requests from a plurality of peripheral devices, and can communicate interrupt information to a processor. Certain examples can reduce the quantity of processor general purpose inputs and outputs configured to receive the peripheral device interrupts in comparison to systems where the peripheral device interrupts are directly coupled to the processor.

International Classification:

H04B 7/14

US Classification:

455 7

Abstract:

In one general aspect, a repeater can include an input terminal configured to be coupled to a first portion of a MIPI signal path. The MIPI signal path being a unidirectional path between a receiver and a transmitter, the input terminal configured to receive a set of signals from the receiver via the MIPI signal path. The repeater can include an output terminal configured to be coupled to a second portion of the MIPI signal path, the first portion of the MIPI signal path and the second portion of the MIPI signal path having a combined distance greater than 30 centimeters.
