  • Patent number: 8311126
    Abstract: A system including a receiver, a TMDS link (or other serial link), and a transmitter configured to transmit K-bit video words (typically, encoded 8-bit video words) over the link. In typical embodiments, the transmitter is configured to pack a sequence of N-bit video words, where N?K (e.g., N=10, 12, or 16, when K=8) into a sequence of K-bit fragments, encode the fragments, and transmit the encoded fragments. The transmitted data are indicative of a sequence of M-fragment groups, and the transmitter is typically configured also to transmit over the link packing phase data indicative of the phase of the most recently transmitted fragment. Other aspects are transmitters and receivers for use in such a system and methods implemented by any such transmitter, receiver, or system.

  • Patent number: 8275026
    Abstract: An adjustable equalizer that includes a first branch including a low pass filter (LPF) and having a variable gain (?), and a second branch including a high pass filter (HPF) and having another variable gain (?). The equalizer can be implemented using CMOS technology so that the gain parameters ? and ? are independently adjustable and the equalizer is capable of equalizing an input indicative of data having a maximum data rate of at least 1 Gb/s. In some embodiments, the equalizer includes two differential pairs of MOS transistors and a controllable current source determines the tail current for each differential pair. When the equalizer includes purely resistive impedances Z0 and Z1, the equalizer's transfer function is Z1/Z0·(?+?·(1+s·C0·Z0)), where ? is a gain parameter determined by the tail current of one differential pair and ? is a gain parameter determined by the tail current of the other differential pair.

  • Patent number: 8086759
    Abstract: In some embodiments, a wall-mountable, configurable controller having control keys (e.g., less than eight keys or another small number of keys), a subassembly including circuitry, and a control key insert removably mountable to the subassembly and including at least one of the control keys. The circuitry can include a limit switch that is biased in a default state but moveable into a learning state in response to user-exerted force. In some embodiments, the controller includes an IR emitter and an IR receiver and is operable to clone another device by sending configuring radiation from the emitter to the other device's IR receiver. Preferably, the emitter and receiver are positioned so that a controller's IR emitter aligns with the IR receiver of an identical controller when the controllers are positioned face to face. In some embodiments, the controller provides audible and visual feedback to users when operating in a learning mode.

  • Patent number: 8064508
    Abstract: An adjustable equalizer that includes a first branch including a low pass filter (LPF) and having a variable gain (?), and a second branch including a high pass filter (HPF) and having another variable gain (?). Outputs of the branches in response to an input signal are summed to produce an equalized output. The equalizer can be implemented using CMOS technology so that the gain parameters ? and ? are independently adjustable and the equalizer is capable of equalizing an input indicative of data having a maximum data rate of at least 1 Gb/s. Typically, the inventive equalizer is embodied in a receiver for use in equalizing a signal, indicative of video or other data, that has propagated over a serial link to the receiver.

  • Patent number: 8021042
    Abstract: An apparatus and method for canceling variations in the beta for a bipolar junction transistor so that the diode equation can be employed to accurately measure the temperature of the transistor based at least in part on a ratio of two target collector currents and two measurements of the base-emitter voltage of the transistor. If the determined collector current of the transistor is relatively equivalent to one of the first and second target collector currents, the transistor's base-emitter voltage is measured and stored. An analog feedback circuit can be employed to change the determined collector current to be relatively equivalent to the first and second target collector currents. The analog feedback circuit can include an optional sample and hold component to further reduce power consumption and reduce noise. A digital circuit can be employed to change the determined collector current to be relatively equivalent to the first and second target collector currents.

  • Patent number: 7991096
    Abstract: A data sampling circuit that employs an oversampling clock to oversample a data signal, a phase tracking circuit for use in such a sampling circuit, and a receiver and system including such a sampling circuit. Preferably, phase tracking is implemented by systematically identifying and rejecting at least one worst sampling position, and sampling the data signal at a non-rejected sampling position. Preferably, phase tracking is accomplished by counting through-transitions of edges of the sampled data signal through each oversampling position, and rejecting an oversampling position having a highest count of through-transitions. In some embodiments, different phase tracking methods (at least one of which includes the step of generating through-transition counts) are used for different types of input data. Other aspects of the invention are methods for determining an oversampling position for oversampling a data signal, and methods for oversampling a data signal including by generating through-transition counts.

  • Patent number: 7797536
    Abstract: In preferred embodiments, a cryptographic device in which two key sets are stored: a normal key set (typically unique to the device) and a test key set (typically used by each of a relatively large number of devices). The device uses the normal key set in a normal operating mode and uses the test key set in at least one test mode which can be a built-in self test mode. Alternatively, the device stores test data (e.g., an intermediate result of an authentication exchange) in addition to or instead of the test key set. In other embodiments, the invention is a cryptographic device including a cache memory which caches a portion of a key set for performing an authentication exchange and/or at least one authentication value generated during an authentication exchange. Other embodiments of the invention are systems including devices that embody the invention and methods that can be performed by systems or devices that embody the invention.

The chip can be implemented by a semiconductor on insulator (SOI) process and can include at least one bipolar or MOS transistor, an insulator underlying the transistor, a semiconductor substrate underlying the insulator, and a metal heat flow path extending between a terminal of the transistor through the insulator to the substrate. Preferably, the metal heat flow path is a metal interconnect formed by a process step (or steps) of the same type performed to produce other metal interconnects of the chip.

  • Patent number: 7608034
    Abstract: Apparatus and method for conditioning an edge of a sheet to be bound so that the edge is conducive to accepting heat activated adhesives used in conventional binding. The sheet is first bent in one direction to form a folding line, with the fold line being a short distance from the edge of the sheet to be conditioned and with that distance being determined primarily by the thickness of the sheet. The bend in the sheet is typically 90 degrees, with the radii of curvature of the opposite sheet surfaces at the fold line being unequal so that a shear force is applied near the sheet end thereby tending to tear or fracture in interior of the sheet near the end. Typically the sheet is then bent in an opposite direction along the folding line so as to produce an opposite shear force that reinforces the creation of tears and fractured in the sheet.

    Abstract: In preferred embodiments, a method and system for pricing a derivative (e.g., a stock option) based on a non-Gaussian price model assuming statistical feedback. The dynamics of the underlying financial instrument (e.g., stock) are assumed to follow a stochastic process with anomalous nonlinear diffusion, phenomenologically modeled as a statistical feedback process within the framework of a generalized thermostatistics. Preferred embodiments implement solutions to a generalized form of the Black-Scholes differential equation, using risk-free asset valuation techniques in some cases.
