摘要： An in-system programmable (ISP) system, having a plurality of ISP devices, can be programmed by remote access from a host controller. The remote access can be accomplished over a wired data network, a wireless data network such as an infra-red data network and a radio wave data network, or a hybrid network including both a wired data network portion and a wireless data network portion. An access interface connects the host controller to an ISP programmer over the wired or wireless communication link. The ISP programmer programs the ISP system in accordance with ISP programming conventions. The ISP programmer can be provided by an integrated circuit having a microprocessor core.

摘要： A programmable logic array (100) includes a set of input terms which are programmably coupled to a first set of AND gates (102-1) through 102-66). The output signals from the first set of AND gates are programambly electrically connected to a second set of AND gates (104-1 through 104-66). The second set of programmable AND gates enhances flexibility of design and permits product terms with a larger number of factors to be generated. The output leads from the second set of AND gates are programmably electrically coupled to a first set of OR gates (106-1 through 106-22) which in turn are programably electrically coupled to a second array of OR gate logic (108-1 through 108-10). This also permits greater design flexibility. The output terms from the second set of OR gate logic can then be used to generate the output signals from the programmable logic array (100). In addition, a bus (110) is programmably electrically coupled to each of the output signals from the second OR logic array and the output signals (O.sub.1 through O.sub.10) of the PLA. Because of this, different output terms can be routed to different output pins thus permitting the designer to select his pin out independently of the availability of gate within specific parts of the array.

摘要： A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) modulation. Space-Time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. OFDM modulation allows for wideband transmission over frequency selective radio channels. A receiver demodulates the OFDM signal and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values. The MIMO demapping and MAP decoding processes exchange likelihood information to improve the bit error rate performance over several iterations of demapping/decoding. By applying well-known turbo-decoding principles to iteratively demap and decode, the overall receiver performance is significantly improved.

摘要： A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with modulating several streams of the BICM encoded data for transmission over two or more antennas. Space-time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. A receiver demodulates the received signals and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values. By applying well-known turbo-decoding principles to iteratively demap and decode, the overall receiver performance is significantly improved. The MIMO demapping and MAP decoding processes exchange likelihood information to improve the bit error rate performance over several iterations of demapping/decoding. By generating tentative decisions for transmitted bits, the overall number of evaluations used for demapping may be reduced.

摘要： A thermally conductive interface adhesive for attaching an electronic component, such as an integrated circuit chip, to a heat receiving substrate, such as a heat spreader, is disclosed. The interface adhesive comprises a mixture of solder powder, flux and a curable polymer, such as an epoxy, which form a paste. Preferably, the interface adhesive further comprises particles of a metallic filler material, such as silver or copper. Preferably, the solder has a relatively low melting point, and the polymer is thermosetting. After the adhesive paste is applied it is processed by heating it to melt the solder after which the polymer is cured, such that a metallic network is formed within the adhesive layer. The cured adhesive layer has a thermal conductivity of about 15 W/m-K or more.

摘要： This invention relates to radioactively coated devices, preferably radioctively coated medical devices. These coated devices are characterized as having a low rate of leaching of the radioisotope from the surface of the coated device and a uniform radioactive coating, and are therefore suitable for use within biological systems. Methods for coating a device with a radioisotope comprising are also disclosed. One method comprises immersing the device within a solution containing a &ggr;, &bgr;+, &agr;, &bgr;− or &egr; (electron capture) emitting radioisotope, then exposing the immersed substrate to tuned vibrational cavitation to produce a coated substrate. A second method involves coating a substrate using electroless plating, and yet a third method involves the use of electroplating a radioisotope onto a substate of interest. With these methods, the coating procedures are followed by baking the coated substrate at a temperature below the recrystallization temperature of the substrate. Substrates coated using the methods of this invention exhibit very low rates of leaching of the coated radioisotope, and are suitable for use within medical applications, for example as stents, catheters, seeds, protheses, vavles, staples and other wound closure devices, where a localized therapeutic treatment is desired.

摘要： A “magic mirror” wand toy has a body having a mirror element that is partially transparent. An image illuminating apparatus is mounted rearward of the mirror element. An image transport apparatus has a plurality of images that can be positioned selectively and alternately in front of the illuminating apparatus. When an image is stationary, it is lit up and an audible message associated with the image may be played.
