Various channels may use various resolutions. A two-channel audio output may be derived from the multi-channel audio data stream during playback. To facilitate an accurate derivation, the mixing coefficients to be used in generating the derivation can be supplied along with the six-channel audio data.

The combination of a synthetic inductive drain load and a bridged-T matching network provide amplifiers that can drive a substantial capacitive load with the above mentioned improvements over prior amplifiers.

Abstract: An apparatus (520) for archiving signatures associated with packets received at a node in a network includes a first memory (620), a second memory (625), a signature tap (610), a multiplexer (615), and a controller (630). The signature tap (610) receives packets at the node and computes one or more signatures for each of the received packets. The multiplexer (615) aggregates the computed one or more signatures in the first memory (620) to produce one or more signature vectors. The controller (630) archives the one or more signature vectors in the second memory (625).

The ball hitting practice apparatus includes a substantially rigid member having a first end and a second end, a hinge capable of suspension from a frame and attached near the first end of the rigid member such that the rigid member rotates about a substantially horizontal axis, and a ball mounting assembly suspended from the second end of the rigid member. Methods for using and making the ball hitting practice are also provided.

Abstract: A pipelined computer processor is presented that reduces data hazards such that high processor utilization is attained. The processor restructures a set of instructions to operate concurrently on multiple pieces of data in multiple passes. One subset of instructions operates on one piece of data while different subsets of instructions operate concurrently on different pieces of data. A validity pipeline tracks the priming and draining of the pipeline processor to ensure that only valid data is written to registers or memory. Pass-dependent addressing is provided to correctly address registers and memory for different pieces of data.

Abstract: A method of processing a communication signal may include computing a number of periodograms from the signal. Each of the periodograms may be generated from a portion of the signal. The number of periodograms may be combined in time sequence to form a spectrogram [510] containing the periodograms. A cepstrogram [520–540] may be generated by performing cepstrum processing on the spectrogram. The cepstrogram may be used to classify [330] the type of communication that produced the signal.

Abstract: A data converter, or “gearbox,” for a padded protocol interface uses a reduced number of components by processing a narrower intermediate data stream, while at the same time multiplying the clock speed of its intermediate input and output so that it processes more data per clock cycle. The data streams can be narrowed to any integer factor of the original width (other than the original width).

Abstract: Electromechanical systems utilizing suspended conducting nanometer-scale beams are provided and may be used in applications, such as, motors, generators, pumps, fans, compressors, propulsion systems, transmitters, receivers, heat engines, heat pumps, magnetic field sensors, kinetic energy storage devices and accelerometers. Such nanometer-scale beams may be provided as, for example, single molecules, single crystal filaments, or nanotubes. When suspended by both ends, these nanometer-scale beams may be caused to rotate about their line of suspension, similar to the motion of a jumprope (or a rotating whip), via electromagnetic or electrostatic forces. This motion may be used, for example, to accelerate molecules of a working substance in a preferred direction, generate electricity from the motion of a working substance molecules, or generate electromagnetic signals. Means of transmitting and controlling currents through these beams are also described.

Abstract: Circuitry and methods allow selected memory word lines (WLs) to be deactivated without using a global deactivate signal. All active WLs do not therefore have to be deactivated simultaneously, which can cause voltage at a common deactivate node to rise undesirably. This undesirable voltage rise can adversely affect a system by, for example, inadvertently activating an inactive WL. The invention advantageously limits the voltage fluctuation at the common deactivate node.

Abstract: Disclosed herein are molecules that include a deoxyribonucleic acid (DNA) covalently bonded to a protein and uses thereof.

Abstract: A programmable logic device is equipped for low voltage differential signaling (“LVDS”) by providing an LVDS input buffer and/or an LVDS output buffer on the device. I/O pins on the device that are used together in pairs for LVDS can alternatively be used individually for other types of signaling. The LVDS buffers are constructed to give good performance and to meet LVDS specifications despite variations due to temperature, manufacturing process inconsistency, and power supply changes.

Abstract: Pre-emphasis circuitry and methods for signal transmission provide multiple levels of output signal amplification over one or more baud periods after an input signal transition. The multiple, gradually decreasing levels of output signal amplification reduce power consumption and better approximate the desired signal response.

Abstract: Systems and methods for packaging integrated circuit chips in castellation wafer level packaging are provided. The active circuit areas of the chips are coupled to castellation blocks and, depending on the embodiment, input/output pads. The castellation blocks and input/output pads are encapsulated and held in place by an encapsulant. When the devices are being fabricated, the castellation blocks and input/output pads are sawed through. If necessary, the wafer portion on which the devices are fabricated may be thinned. The packages may be used as a leadless chip carrier package or may be stacked on top of one another. When stacked, the respective contacts of the packages are preferably coupled. Data may be written to, and received from, packaged chips when a chip is activated. Chips may be activated by applying the appropriate signal or signals to the appropriate contact or contacts.

Abstract: A Three-Dimensional Structure (3DS) Memory allows for physical separation of the memory circuits and the control logic circuit onto different layers such that each layer may be separately optimized. One control logic circuit suffices for several memory circuits, reducing cost. Fabrication of 3DS memory involves thinning of the memory circuit to less than 50 ?m in thickness and bonding the circuit to a circuit stack while still in wafer substrate form. Fine-grain high density inter-layer vertical bus connections are used. The 3DS memory manufacturing method enables several performance and physical size efficiencies, and is implemented with established semiconductor processing techniques.
