  • Patent number: 7772925
    Abstract: Amplifier apparatus comprising a power amplifier having an operating frequency in the radio frequency or microwave or higher ranges and a pre-distorter, the characteristics of the power amplifier comprising a distortion from a linear transfer function. The pre-distorter comprises a non-linear path and a linear path including amplifiers having substantially identical physical characteristics, an input divider responsive to an amplifier input signal for applying respective pre-distorter input signals to the paths, and an output coupler for combining the signals from the linear path and the non-linear path to produce a pre-distorted signal. The characteristics of the pre-distorter comprise a distortion relative to a linear transfer function that compensates for the distortion of the transfer function of the power amplifier.

  • Patent number: 7770929
    Abstract: A locking mechanism of an inertia reel assembly of a vehicular seatbelt restraint system is selectively disabled based on a latch status of a seatbelt buckle of the seatbelt restraint system. In one embodiment, a sensor at a latch assembly determines whether the seatbelt buckle is engaged with the latch assembly and provides an output signal based on this determination. A controller receives the output signal and selectively drives an actuator based on the output signal so as to enable or disable the locking mechanism of the inertia reel assembly. By disabling the locking mechanism of the inertia reel assembly when the seatbelt buckle is detected as unlatched, an occupant is able to quickly latch the seatbelt buckle even in the event of an inertial event that otherwise would have prevented any further extension of the seatbelt.

  • Patent number: 7774584
    Abstract: The apparatus and method herein splits the function of a digital subscriber line (DSL) modem data pump between a digital signal processor (DSP 106) and a general purpose host central processing unit (CPU 102). The DSP (106) handles all front end data pump processing such as interface to an analog front end (108 and 110), FFT processing, FEQ processing, QAM decoding, and bit formatting. The host CPU (102) handles all back end data pump processing such as DMT tone deordering, data deinterleaving, error detection and correcting, bit descrambling, CRC processing, and the like. In order to enable the DSP (106) and the CPU (102) to communicate with each other effectively, buffers (132) under the control of specialized buffer management methodology (FIG. 4) are used.

  • Patent number: 7773672
    Abstract: A rate control system for a video encoder including rate control logic which determines a first QP corresponding to a selected encoding layer of multiple encoding layers, and scaling logic configured to scale the first QP to a second QP corresponding to any other encoding layer based on at least one encoding layer parameter. A template of stored QP values may be used to reduce computational complexity, such as a QP value for each frame interval or a QP value for each of multiple rate control interval complexity values. The QP values in the template may be predetermined or programmed and updated during periodic training sessions. Several encoding layer parameters are contemplated, such as any combination of bit rate, frame rate and frame resolution. The scaling logic may be configured to scale from any one encoding layer to another and vice-versa for bi-directional scaling.

  • Patent number: 7772584
    Abstract: A semiconductor device has lateral conductors or traces that are formed of nanotubes such as carbon. A sacrificial layer is formed overlying the substrate. A dielectric layer is formed overlying the sacrificial layer. A lateral opening is formed by removing a portion of the dielectric layer and the sacrificial layer which is located between two columns of metallic catalysts. The lateral opening includes a neck portion and a cavity portion which is used as a constrained space to grow a nanotube. A plasma is used to apply electric charge that forms an electric field which controls the direction of formation of the nanotubes. Nanotubes from each column of metallic catalyst are laterally grown and either abut or merge into one nanotube. Contact to the nanotube may be made from either the neck portion or the columns of metallic catalysts.

  • Patent number: 7772048
    Abstract: A semiconductor device is made by steps of removing portions of a first capping layer, removing portions of a sacrificial layer, recessing sidewalls, and forming fin structures. The step of removing portions of the first capping layer forms a first capping structure that covers portions of the sacrificial layer. The step of removing portions of the sacrificial layer removes portions of the sacrificial layer that are not covered by the first capping structure to define an intermediate structure. The step of recessing the sidewalls recesses sidewalls of the intermediate structure relative to edge regions of the first capping structure to form a sacrificial structure having recessed sidewalls. The step of forming fin structures forms fin structures adjacent to the recessed sidewalls.

  • Publication number: 20100195733
    Abstract: A method of encoding a video frame is disclosed in which video slices of the video frame are initially encoded in parallel using both interframe encoding and intraframe encoding. Then, after a first predetermined minimum amount of the video frame has been encoded, the method includes periodically determining whether the amount of intraframe encoded information for the frame achieves a first threshold, and when the first threshold is achieved, encoding the remainder of the video frame using only intraframe encoding. The method may include determining whether a lower second threshold is achieved based on relative complexity of the frame and quantization. The method may include performing similar comparisons on a slice by slice basis in which any one or more of the processing devices skips motion estimation and interframe encoding for corresponding video slices. A video encoder is disclosed which includes multiple processing devices and a shared memory.

  • Patent number: 7768296
    Abstract: A current boost module receives a signal from the input and the output of a buffer to determine whether the buffer is transitioning between logic states. When the buffer is transitioning, a boost current is provided to a load connected to the buffer output to supplement the current from buffer output, thereby facilitating transition of a signal at the load. The current boost module can shut down the boost current before the signal at the load completes its transition from one logic state to the other.
