摘要： A new method for making a nonlinear optical structure for frequency conversion and for using that structure for frequency conversion is described. The nonlinear optical structure is made by depositing alternating contiguous layers of gallium arsenide and aluminum gallium arsenide onto a gallium arsenide substrate. Optical frequency conversion is performed by transmitting a pump laser beam through the structure. The new method is easier to perform than prior art methods.

摘要： An open collector/open drain interface, such as I2C interface between two or more integrated circuit devices, employs isolation techniques to provide electrical isolation of a digital signal for transmission of the signal between the devices. Uni-directional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended transmission direction is performed by direction control logic. Edge detection logic is utilized to determine changes in edges of a digital signal, thus determining a transmitting device and a transmission direction. The direction state is held in a direction state register. This state is held until the appropriate edge is detected on the transmit side, returning the isolator to the idle state. In the idle state neither side of the isolator is in a driven state. During transmission, the digital signal is transmitted through an isolator channel and sent to a receiving device.

摘要： A system and method is described for providing an interactive rich media information service to users of mobile devices. The rich media information is presented to users in a plurality of interactive rich media channels. A subscriber-specific data stream is received at the mobile device containing channel data for each of the rich media channel that the user has subscribed to. The channel data is separated and stored corresponding to each such subscribed-to channel. An interactive multimedia runtime container (iMRC). is executed on the mobile device for each subscribed-to channel. The rich media channels are played on the iMRC and displayed on the display of the mobile device. Using the user interface elements of the mobile device, the user may navigate through the information on the channels, navigate between different channels, subscribe or un-subscribe to channels, and enter user preferences for further tailoring the information presented in the subscribed-to channels.

摘要： The present invention is a process and apparatus for the synthesis and growth of single crystals of phosphorus compounds starting with the elemental materials in a single furnace without external exposure. The apparatus of the present invention is a crystal growth furnace heated by RF coils. Inside the furnace is a susceptor for holding a crucible. Above the crucible is selectively positioned a phosphorus improved injector. The non-phosphorus materials are placed in the crucible and melted to a desired temperature. The phosphorus material previously placed within the injector is heated by the radiant heat from the crucible to drive the phosphorus vapor into the melt through a tube. This is closely controlled by noting the temperature within the injector and adjusting the height of the injector above the melt to control the temperature within the phosphorus material. After the formation of the stoichiometric melt, the seed is inserted into the melt for crystal growth if so desired. A further improvement to the above apparatus is the use of an improved injector having a cover and a shield thereabout. The injector and cover have a central hole through which the seed is inserted. The injector is moved vertically within the cover to provide the proper temperature therein.

摘要： An interface between two or more integrated circuit devices employs isolation techniques to provide electrical isolation of a digital signal for transmission of the digital signal between a master device and one or more slave devices. Unidirectional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended direction is performed by direction control logic. Logic that monitors read and write transactions operates to determine a desired direction of the digital signal and accordingly directs the digital signal through an appropriate isolator channel.

摘要： A present invention Galois field multiplier system and method utilize lookup tables to generate one partial product term and one feedback term in one clock cycle. In one embodiment, a Galois field multiplier system includes a plurality of shift registers, a plurality of exclusive OR components, a partial product lookup table, and a feedback table lookup table. The plurality of shift registers perform shift multiplication operation and are coupled to the plurality of shift registers that perform addition operations. The partial product lookup table and feedback lookup tables are selectively coupled to the exclusive OR components and values from the partial product lookup table and feedback lookup tables are fed into the selectively coupled exclusive OR components. Coefficients of the partial product term and feedback term are utilized as indexes to the partial product lookup table and feedback lookup table respectively.
