Method and system for maintaining a guaranteed quality of service in data transfers within a communications system

Abstract: A cable telephony system (100) including a plurality of subscriber units (104) connected to a head-end (102) by a cable distribution network (106) in which upstream and downstream data transmissions are sent between subscribers (104) and head-end (102). Both shared and unshared connections are supported within cable telephony system (100). Transmission between a subscriber (104) and head-end (102) may involve both a shared and unshared connection in which unshared connections are employed to provide a higher quality of service when the shared connection is unable to do so.

Serial scan chain architecture for a data processing system and method of operation

Abstract: A scan chain architecture which has a controller (10), and a multiplexer (24) is used to route test data through functional units (12, 14, 16, 18, 20, and 22). The controller (10) receives as input a serial data stream from an STDI terminal and demultiplexes this data stream to one of the functional units (six functional units are illustrated in FIG. 1). Each of the functional units is considered as one scan chain and therefore FIG. 1 has six scan chains (one for each functional unit). In addition, a seventh scan chain couples all output flip-flops in each of the functional units together between an output of the MUX (24) and the STDO terminal/pin. Therefore, a serial scan of a data stream can be done through one functional unit, the multiplexer (24) and into the output flip-flops of each function unit to make testing easier to set-up. In addition, various new scan chain cells and low power methods are used herein.

Systems and methods for syncronizing multiple electronic devices

Abstract: Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.

Flexible substrate folded in a U-shape with a rigidizer plate located in the notch of the U-shape

Abstract: Semiconductor carrier assemblies (10, 40) use a flexible substrate (11) to connect to at least one semiconductor device (19) Preferably the flexible substrate (11) also connects to a circuit component, preferably a circuit board (31) The flexible substrate (11) is configured in a U-shaped configuration having at least one rigidizer plate (25; 41, 42) positioned in the notch of the U Interconnections between the semiconductor device (19) and the flexible substrate (11), and, preferably, the circuit component (31) are provided by solder connections (22, 28) Preferably, two rigidizer plates (41,42) having different temperature coefficients of expansion are positioned in the notch of the U of the flexible substrate (11) and preferably a low modulus adhesive layer (50, 51, 47) is utilized in the assembly to minimize thermal stress

Apparatus and method for name resolution in an aggregation of mobile networks

Abstract: A method and apparatus are provided for establishing internet protocol (IP) communication with a node in an aggregation of one or more mobile networks each having a name server. The method includes multicasting ( 105 ) at least one message to the mobile networks indicating a name resolution of at least one mobile network in the aggregation, and determining ( 110 ) an IP address of the node from the name resolution(s) indicated by the multicasted message(s). The name resolution is based on a domain name of the name server of a corresponding mobile network in the aggregation.
