Abstract: A system and method for distributing data in a system. The system comprises a control register logic circuits located at scattered locations in the system, where a location is defined as scattered if the propagation delay of data sent from the control register is more than approximately one clock period. The system also comprises one or more shift registers coupled to the control register and the logic circuits. A section of each shift register is placed in proximity to each logic circuit and data is shifted serially from the control register through the shift registers to the logic circuits. A synchronizer circuit is coupled to the shift registers to synchronize data arriving at each section of the shift registers with a shift control signal arriving at the same section of the shift register.

Abstract: The present invention is directed to systems for and methods of using dual mode handsets or softphone client for voice, sms, and data services. In one embodiment of the present invention, a mobile handset uses a SIP User Agent to register on a visiting network. The mobile handset generates SIP REGISTER messages. The SIP REGISTER messages are translated into corresponding MAP registration (or RADIUS message) and authentication commands, allowing system to contact the HPLMN HLR (or home AAA) associated with the mobile device to authenticate the mobile device and register it on a VLR of a visiting network. MAP responses (or RADIUS response) are translated to corresponding SIP commands that are forwarded to the mobile device, thereby completing the connection set up.

Abstract: A system and method for encoding page size information has been described herein. In one embodiment, the method includes determining whether a virtual address is stored in a translation lookaside buffer (TLB), the TLB including a plurality of entries, wherein the entries include a minimum virtual page number bit string and a variable bit string. In one embodiment the method also includes determining whether the first bit string matches the minimum virtual page number bit string of one of the entries. In one embodiment, if the first bit string matches the minimum virtual page number bit string of one of the entries, the method includes decoding a page size stored in the variable portion of the matching entry and a 1-bit field associated with the matching entry, wherein the decoding determines a set of bits of the variable bit string.

Abstract: An apparatus and method of treating multiple wafers to reduce the density of impurities as well as to improve the uniformity of substrate electrical characteristics without any thermal stress. The wafers are chemically treated, and heat treated in a sealed reaction tube under arsenic overpressure with a controlled thermal profile to heat the wafers. The thermal profile controls temperature of different zones inside of a furnace containing the sealed reaction tube. Impurities of the wafers are dissolved, and are out-diffused from the inner portions to the outer portions of the wafers.

Abstract: A method and system for resolving virtual addresses using a page size tag are described herein. In one embodiment, the method comprises translating a virtual memory address into physical memory address. According to the method, the translating includes producing a first page size tag and choosing an entry in a translation lookaside buffer, wherein the entry stores a second page size tag and a page frame number. The method also includes comparing the first page size tag with the second page size tag. The method also includes using the page frame number to form the physical memory address, if the first page size tag is less than or equal to the second page size tag.

Abstract: The present invention relates to methods for identification and quantification of proteins expressed within a cell. The methods of the invention involve the separation of proteins based on their physical properties such as, for example, net charge, molecular weight, or immunoreactivity, followed by detection of said proteins using a number of different techniques including (i) ramification-extension amplification method (RAM); (ii) hybridization signal amplification method (HSAM); and (iii) detection with nanodots. The methods of the invention will have a variety of different uses including, but not limited to, uses for screening, for diagnosis and prognosis of disease. The methods of the invention are especially useful for identification of proteins that are not easily identified due to the small size of the protein, low concentration of the protein, or failure to separate proteins due to similar physical properties.
