  • Patent number: 7050576
    Abstract: A state machine for attenuating the transition into and out of NLP state to reduce voice clipping and to reduce echo leak in a voice over packet signal transmission. The state machine interposes two additional transitional states between the NLP active state and the NLP inactive state to eliminate the sharp transition of NLP activity. An NLP entering state is used to gradually reduce the mixing ratio of echo and voice to attenuate the transition from passage of echo in the NLP inactive state to the suppression of echo in the NLP active state. An NLP exiting state is used to gradually increase (ramping the change) the mixing ratio of echo and voice to attenuate the transition from suppression of echo in the NLP active state to passage of echo in the NLP inactive state.

  • Patent number: 7049986
    Abstract: A parameter of an integrated circuit including a first trim array and a second trim array is trimmed by measuring an initial value of the parameter, determining whether the parameter exceeds a reference value, and as long as the parameter exceeds the reference value, repetitively blowing fuses associated with binarily weighted trim elements of the first trim array to eliminate trim contributions thereof to thereby decrease the parameter by weighted amounts corresponding to a present trim array bit number value until either all fuses of the first trim array have been blown or enough have been blown to cause the parameter to be less than a ?LSB/2 weight. If the parameter then is less than the ?LSB/2 weight, a fuse of the second trim array corresponding to a present bit number is blown to increase the parameter to greater than a +LSB/2 weight. The procedure is repeated until all fuses in one trim array have been blown, to thereby minimize the number of residual trim elements.

  • Patent number: 7049842
    Abstract: An integrated circuit functionality test determining shorts between adjacent pins of all the IC pins while simultaneously determining pin continuity in only three steps. The process includes categorizing all pins of the IC into three sets of pins. One set of pins is connected to digital instruments, a second set of pins is connected to 0 volts, and a third set of pins is left open. The digital instruments sink current in parallel from the first set of pins to identify any shorts of the first set of pins. The process is repeated for each of the other two sets of pins. For IC packages having double and quad terminal positions, each terminal position is treated like a single terminal position, and the measurements of the respective sets of pins of each terminal position is measured in parallel.

  • Patent number: 7049242
    Abstract: The present invention provides a method for fabricating a dual gate semiconductor device. In one aspect, the method comprises forming a nitridated, high voltage gate dielectric layer over a semiconductor substrate, patterning a photoresist over the nitridated, high voltage gate dielectric layer to expose the nitridated, high voltage dielectric within a low voltage region wherein the patterning leaves an accelerant residue on the exposed nitridated, high voltage gate dielectric layer. The method further includes subjecting the exposed nitridated, high voltage dielectric to a plasma to remove the accelerant residue.

  • Patent number: 7051197
    Abstract: A method of tracing a data processor upon reset of the data processor. A data processor reset signal resets the data processor, part of trace collection hardware and does not reset remaining parts of trace collection hardware. The data processor reset signal may be not owned, owned by an application program or owned by a debugger. The partial not reset of the trace collection hardware occurs only upon a data processor reset signal owned by the debugger. A trace logic reset signal resets both the data processor and the trace collection hardware when not owned. This trace logic reset signal resets the data processor only when owned by the debugger and resets the trace collection hardware when owned by an application program.

  • Patent number: 7050402
    Abstract: A probe, listen and select (PLS) technique can be used to select from an available frequency spectrum a frequency band whose communication quality is suitable for wireless communication at a desired rate. Probe packets can be transmitted on different frequencies (223) during a known period of time (TPLS), and frequency channel quality information can be obtained (225) from the probe packets. This quality information can then be used to select a desirable frequency band (227). The communication quality of the selected band can also be used as basis for selecting (141) from among a plurality of modulation and coding combinations that are available for use in communications operations.

  • Patent number: 7050187
    Abstract: A device and method for providing real time compensation for packet loss in the transmission of facsimile data over packet networks to avoid the generation of page loss data and the termination of facsimile transmission. Facsimile devices have a low tolerance for interruptions in transmission. Packet networks commonly have a transmission interruption rate above the tolerance of facsimile equipment. In order to compensate for transmission interruption, the present invention teaches the buffering of facsimile data by scan line at the receiving end, the evaluation of buffered scan lines for packet loss and the discarding of scan lines having packet loss to conceal the packet loss from the receiving facsimile equipment to avoid detection of page errors by the receiving facsimile equipment which could cause loss of facsimile transmission.

A second body is formed with a force transfer portion (14a, 24g, 30d, 36b, 52a, 70a, 94a) permanently attached to the first body along an outer periphery circumscribing the sense surface. The piezoresistors are electrically connected to conditioning electronics received in a chamber formed between the two bodies. The effects of parasitic loads on the sense element are minimized by selected placement of the piezoresistors on the sense surface.

  • Patent number: 7046069
    Abstract: Modularized clock decoupling and signal delay management is provided for the purpose of reducing simultaneous binary signal switch-induced inductive voltage transients in lower voltage synchronous semiconductor devices. The voltage levels in low-voltage devices must be tightly maintained for proper transistor logic operations. Signal switching results in current changes on the power net of an IC. Current changes produce inductive voltage transients which propagate throughout the device and which can interfere with signal transmission and device operation. Relatively independent functioning circuits of an integrated circuit are isolated from the chip clock and each isolated circuit module is provided with its own independent, same-frequency, but slightly out-of-phase clock signal. Signal switching within any module is thus occurring out-of-phase with that of all other modules and, as a result, switch-associated voltage transients are limited to those associated with one module's circuits at a time.
