  • Publication number: 20070294624
    Abstract: The subject application is directed to a system and method for customizing a document processor interface. A user successfully logs onto a document processing device and selects to generate a customized graphical user-interface. When the user has previously created such an interface, the device retrieves stored selection data associated with the user and uses such data to selectively generate a customized interface. To create the customized interface, the user first selects desired functions to be displayed. The selected functions are then stored in association with user identification information by the device. A tangible output document is capable of being generated inclusive of encoded indicia representing selection data and user identification information.

  • Publication number: 20070290731
    Abstract: An integrated circuit is configured with a pin for specifying a reset configuration vector of a circuitry within the integrated circuit. The resistance value of a low cost external resistor coupled to the pin is detected and utilized to identify the configuration. Logic on the integrated circuit detects and utilizes the resistor value to index to a configuration vector in a look-up table. The integrated circuit is then configured in accordance with the indexed configuration vector.

  • Patent number: 7293220
    Abstract: An apparatus and method for accessing data from a storage medium is disclosed. The apparatus fetches a data block from the storage medium via an accessing unit, and corrects an error of the data block by an error correction code (ECC) decoder according to an ECC of the data block.

  • Publication number: 20070255886
    Abstract: A programmable logic device (PLD) includes a central processing unit (CPU) and a programmable interface coupled to the CPU, wherein the programmable interface includes a core designated by a user. The programmable interface core allows devices, both on and off-chip, to communicate with the CPU. In one embodiment, the programmable interface core includes a crosspoint switch for coupling a plurality of devices and the CPU. Re-programmability of the PLD provides significant flexibility in providing features that can be parameterized based on the user's needs and/or associated design. Specifically, these parameterized features can be implemented in programmable resources on the PLD, thereby allowing these features to be modified at any time. Moreover, only those resources actually needed for the programmable interface core need be implemented, thereby allowing the user to optimize use of the remainder of the PLD.

  • Publication number: 20070191911
    Abstract: The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the threshold of perception. Alternatively, electrode height may be measured directly to predict the threshold of perception. Also, impedance measurement may be used to quickly identify defective electrodes and proper electrode placement.
