  • Publication number: 20080192410
    Abstract: The invention relates to a peripheral unit system that provides a universally usable system for adding peripheral functions to off-the-shelf handheld host devices of variable size and configuration. The system and methods according to the invention allow adaptation to variably sized handheld host devices without the need to customize the peripheral unit to the host device. The invention provides added functionality such as increased ruggedness and durability, while providing an integrated system in association with a handheld host device, to provide the convenience of a one-piece form-factor, without sacrificing universality of the solution. The peripheral unit comprises a housing having a portion configured to engage with a handheld host device of various sizes and electrical configurations. An attachment mechanism is associated with the housing, being used to selectively secure the housing to the handheld host device to form a one-piece apparatus suitable for handheld use.

  • Patent number: 7403577
    Abstract: A computation efficient polyphase channelization system enables one of many user FDMA signals to be channelized through multiple FFT response frequency bands forming an aggregate frequency band where K-point FFT channels are greater than the decimation factor M to produce FFT overlapped responses that have a smooth aggregate response without disjointed band gaps for reduced distortion using a clockwise commutator having M channels feeding M filter blocks, each of which having ? polyphase filters, and having a ring switch to provide smooth filter responses that then drive ? K-point FFTs to provide a ? set of K vector FFT responses that are then combined in a post processing system for producing K channelized outputs.

  • Patent number: 7388881
    Abstract: A system for receiving and handling a scrambled input data signal that includes a preamble with a start of frame delimiter (SFD) initiates an SFD search on the scrambled input data, thereby attempting to save an initialization period. The initialization period may be of the order of 7 uS, and its saving results in improved timeline management enabling antenna diversity and the possible use of high performance algorithms. The system may use two parallel paths for signal processing, each having an SFD detector and a descrambler. If the detected SFD is short, then the second path is disabled, and if it is long, then the first parallel path is disabled. Alternatively, the first path can be used for a finite period of time (for e.g., 40 symbols) and if the SFD is still not detected, the first path is disabled, and the system uses only the second path.

  • Publication number: 20080127152
    Abstract: A computer program product and computer system for implementing a method of compiler optimisation of source code during compilation of the source code in a computer environment. The compiler optimisation of source code includes: recasting two algebraic expressions into a form of one or more token pairs arranged sequentially in a string, each token pair including an operator followed by an operand; reducing the strings in accordance with a set of predetermined simplifying rules; and comparing the reduced strings by matching to detect an equivalence of the two algebraic expressions.

  • Patent number: 7340522
    Abstract: A method and system for resource allocation. Specifically, in one embodiment, a method begins by receiving a request for an interactive session from a user. The request also comprises a resource requirement profile. Then, the method continues by selecting a computing resource having an affinity to the user. The computing resource is selected from a plurality of computing resources that are available to the user. The selected computing resource is implemented to support the interactive session. Thereafter, the selected computing resource is assigned to the user for use in the interactive session.
