Abstract: A test fixture and method for mechanical testing of production samples of semiconductor chips that have been packaged and mounted on a printed circuit board. The sample is isolated and attached to a loading arm using an adhesive. The test fixture includes at least four plates disposed in a spaced-apart relationship along a testing axis. At least six rods are used to maintain this alignment. A first rod set of at least three rods is fixed in a first direction along the testing axis. The first rod set extends parallel to the testing axis through openings formed in a second plate to the third plate, to which the first rod set is fixed in at least a second direction along the testing axis, the second direction being opposite to the first direction. Similarly, a second set of at least three rods are fixed in the first direction to a second plate, extend along the testing axis through openings formed in the third plate, and are fixed in a second direction to the fourth plate.

Abstract: The present invention includes an intelligent router and method for improving the routing of datagrams, resulting in increased effective bandwidth over networks of high latency. The intelligent router can be used alone or in combination with a second intelligent router. An intelligent router buffers data bound for a destination node within the router itself until the destination node has available space. In addition, the intelligent router of the present invention may continue to transmit a datagram without waiting for confirmation of receipt of a previous datagram. Also, retransmission requests can be ignored until a later time to accommodate for the delay in the network. When using multiple intelligent routers communicating with each other, only the erroneous portions of individual datagrams need to be resent. Routing between two intelligent routers eliminate or reduces the transmission of redundant data being sent.

Abstract: Apparatus, and an associated method, for a UWC-136 HS communication system is provided. A synchronization signal generated by the network infrastructure, constructed generally corresponding to the existing IS-136/136+ standard is received by a mobile station operable, generally, pursuant to the timing scheme defined in a GSM system. A relative timing offset between the timing schemes of the respective communication system schemes is determined and thereafter utilized for purposes of synchronization.

Abstract: A frequency equalizer, and an associated method, for radio telephone to cause the tonal characteristics of audio signals generated by the radio telephone to exhibit a desired sound. Selectable groups of preset amplification levels are stored at the radio telephone which define equalization curves. Selection by a user of the radio telephone of a selected equalization curve causes the frequency equalizer to selectively amplify portions of a signal representative of a receive signal provided to the frequency equalizer. Once amplified in this manner, the amplified signal is provided to an acoustic transducer whereat an audio signal is formed.

Abstract: A multi-level NAND architecture non-volatile memory device reads and programs memory cells, each cell storing more than one bit of data, by comparing to a constant current level while selectively adjusting the gate voltage on the cell or cells being read or programmed. A plurality of read and write reference cells are provided each programmed to correspond to one each of the multi-level programming wherein during reading of the memory cells, the read reference cells provide the constant current level and during writing to the memory cells, the write reference cells provide the same. Furthermore, during a read operation, corresponding write reference cells are coupled to read reference cells to gauge the reading time associated with reading of memory cells.
