  • Publication number: 20140347634
    Abstract: A solid state illumination system is provided for image projection. Red, green and blue light is generated using a blue laser light source and phosphor emissions. The red, green and blue light is passed by TIR or TRIR elements of red, green and blue light channels of an X-cube prism structure for separate modulation by different spatial light modulators. The modulated red, green and blue light is passed by the TIR or TRIR elements into the X-cube and combined into a combined modulated RGB image forming light stream for image formation via projection optics onto a target imaging surface.

  • Patent number: 8896610
    Abstract: In at least some embodiments, an apparatus includes a hardware accelerator subsystem with a pipeline. The hardware accelerator subsystem is configured to perform error recovery operations in response to a bit stream error. The error recovery operations comprise a pipe-down process to completely decode a data block that is already in the pipeline, an overwrite process to overwrite commands in the hardware accelerator subsystem with null operations (NOPs) once the pipe-down process is complete, and a pipe-up process to restart decoding operations of the pipeline at a next synchronization point.

  • Patent number: 8897217
    Abstract: A system and method for providing wireless communications between a medical controller hub and an implant node are disclosed. The hub transmits signals to facilitate communication connections with the node. The signals include connection invitation polls with identification parameters. A node monitors the hub's transmissions for the connection invitation polls. When a poll is detected, the node compares the identification parameters to a list of preferred identification values. If the received identification parameter is on the preferred list, and the node and hub are not already connected, then the node responds to the connection invitation poll. If the received identification parameter is not on the preferred list, then the node continues to monitor hub transmissions for other connection invitation polls that include identification parameters that are on the preferred list.

  • Patent number: 8896950
    Abstract: A circuit includes an input that receives a current that increases as a tunneling current sensor moves closer to a media. A high gain path is operatively coupled to the input to amplify the received current as a first amplified output. The first amplified output increases until a saturation threshold is attained for the high gain path. Further increases in the received current beyond the saturation threshold are diverted from the input as an overflow current. A low gain path is operatively coupled to the input to amplify the overflow current as a second amplified output. The second amplified output increases with the overflow current as the tunneling current sensor continues to move closer to the media.

  • Patent number: 8898528
    Abstract: A process and apparatus provide a JTAG TAP controller (302) to access a JTAG TAP domain (106) of a device using a reduced pin count, high speed DDR interface (202). The access is accomplished by combining the separate TDI and TMS signals from the TAP controller into a single signal and communicating the TDI and TMS signals of the single signal on the rising and falling edges of the TCK driving the DDR interface. The TAP domain may be coupled to the TAP controller in a point to point fashion or in an addressable bus fashion. The access to the TAP domain may be used for JTAG based device testing, debugging, programming, or other type of JTAG based operation.

  • Publication number: 20140341172
    Abstract: A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).

  • Publication number: 20140340058
    Abstract: Power-supply ripple rejection (PSRR) at high frequencies is improved for an LDO voltage regulator with an NMOS pass transistor (MN1). A ripple voltage (Vripple) present on the input voltage causes a ripple current (Iripple) through parasitic gate-drain capacitance of the pass transistor. A small ripple current (Ifraction) proportional to the ripple current (Iripple) is generated and amplified to generate a cancellation current (Icancel). The cancellation current is drawn from the gate of NMOS pass transistor (MN1) to cancel the ripple current so that no net ripple current flows through the finite output impedance of an error amplifier (2), to thereby achieve the PSRR improvement.
