  • Patent number: 8156539
    Abstract: A method and system for protecting a wireless network by establishing virtual walls to confine wireless connection to devices located within a three-dimensional region. A network of wireless monitoring nodes is established at physical locations. The monitoring nodes are arranged in a frame of reference and determine locations of one another and of mobile nodes by conducting measurements of either roundtrip travel time of signals sent and received or of differences in the times of receiving a signal at different known locations. Initially mobile nodes are placed, sequentially, in a triangle at a boundary to be established as a virtual wall for confining communication within the wireless network. The mobile node locations are then stored. The position of a device requesting admission to the wireless network is similarly determined and, if within the established virtual walls, the device may be admitted to the network. Admission is otherwise denied.

  • Patent number: 8154088
    Abstract: Improved semiconductor topographies and methods are provided herein for reducing the gate induced drain leakage (GIDL) associated with MOS transistors. In particular, a disposable spacer layer is used as an additional mask during implantation of one or more source/drain regions. The physical spacing between the gate and the source/drain regions of a MOS transistor (i.e., the gate/drain overlap) can be varied by varying the thickness of the disposable spacer layer. For example, a larger spacer layer thickness may be used to decrease the gate/drain overlap and reduce the GIDL associated with the MOS transistor. The disposable spacer layer is completely removed after implantation to enable electrical contact between the source/drain regions and subsequently formed source/drain contacts. A method is also provided herein for independently customizing the amount of current leakage associated with two or more MOS transistors.

  • Patent number: 8149048
    Abstract: An apparatus and method for programmable power management in a programmable analog circuit block. Specifically, the present invention describes an operational amplifier circuit that includes current sources that are coupled in parallel. Configuration bits are asserted to selectively enable or selectively disable one or more of the current sources in order to modulate the performance of the operational amplifier circuit block. Selective addition or removal of current sources increases or decreases the amount of current within the operational amplifier and, correspondingly, the speed and power consumption of the operational amplifier. Combinations of asserted configuration bits pass a bias voltage in order enable selected current sources. In one embodiment, the bias voltage can be increased in order to increase the current output of one of the current sources which, correspondingly, increases the speed of the operational amplifier circuit block.

  • Patent number: 8145809
    Abstract: An embodiment of the present invention is directed to a system for synchronizing independent time domain information. The synchronization of the device resource access information allows a memory access device to reliably access memory in a time domain independent of a device issuing requests. The system may synchronize device resource information for requests made by a processor to access (e.g., read/write) locations of a memory device. The present invention synchronizes the device access information without restricting pulse width of a read/write signal or requiring a high speed clock.
