20130343365 | METHODS AND APPARATUS FOR SYNCHRONIZATION AMONG INTEGRATED CIRCUITS WITHIN A WIRELESS NETWORK - Methods and apparatus for synchronization of integrated circuits (ICs) within a wireless network. In one embodiment, a serial time protocol (STP) is disclosed for use within a wireless device of a wireless network. The disclosed STP provides a common protocol for communicating precision time information from one time-transmitter IC to another time-receiver IC within a wireless device. In one exemplary implementation, a time-transmitter and a time-receiver are implemented within the firmware of a wireless device. Various schemes utilizing the disclosed STP for time synchronization are also described. | 12-26-2013 |
20140281076 | METHODS AND APPARATUS FOR MULTI-DROP DIGITAL BUS - Apparatus and methods for digital bus operation. In one embodiment, the digital bus is a bidirectional, time-division multiplexing (TDM) audio bus operation, and a bus technology is described that enables multi-drop (e.g., multiple device, multiple node, etc.) connectivity for real-time audio over a small form factor interface (e.g., as few as two (2) wires). Specifically, an exemplary tri-level signaling scheme provides bidirectional functionality, real-time clock edges, audio data, in a multi-drop topology in one implementation. | 09-18-2014 |

20110104940 | THERMAL PROTECTION CIRCUITS FOR ELECTRONIC DEVICE CABLES - Connectors for cables such as a 30-pin connector are provided. The connectors may have thermal protection circuits and may carry a power supply voltage and a ground voltage. The thermal protection circuits may disable the power supply voltage when the temperature of the connector exceeds a threshold value. The thermal protection circuits may disable the power supply voltage when liquid is detected in the connector. The thermal protection circuits may disable the power supply voltage permanently or temporarily. In one example, when a cable is reset, the thermal protection circuits may use a record of previous fault events and measurements from thermal and liquid sensors to determine whether to enable or disable the power supply voltage. | 05-05-2011 |
20130222698 | Cable with Video Processing Capability - In an embodiment, a host computing device includes an internal display and also includes a connector to connect to an external display. A cable is provided to connect to the connector and to connect to the external display. The cable includes video processing capabilities. For example, the cable may include a memory configured to store a frame buffer. The frame buffer may store a frame of video data for further processing by the video processing device in the cable.

20130301635 | Methods and Apparatus for Synchronizing Clock Signals in a Wireless System - A system for verifying clock synchronization between master and slave network equipment is provided. The master includes a transmitter, first control logic, and a first processor. The slave includes a receiver, second control logic, and a second processor. The transmitter may send synchronization packets to the receiver. When a synchronization packet is sent, the first control logic forwards a first timestamp sample to the first processor. In response to receiving a synchronization packet, the receiver may generate a second timestamp sample that is forwarded to the second processor. When a number of first timestamp samples are collected at the first processor, the transmitter may send a timestamp packet to the receiver. In response to receiving the timestamp packet, the receiver may compare the first and second timestamp samples in an effort to synchronize a slave reference clock in the slave to a master reference clock in the master. | 11-14-2013 |
20140070774 | CASCADING POWER FOR ACCESSORIES - Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described.
