  • Patent number: 7871009
    Abstract: Maintaining faulty radio frequency identification (RFID) labels on a surface of a web carrier. The various embodiments of the invention provide apparatus for controlling whether RFID labels are separated from a label web. In one embodiment, a frame has first and second side members, and a peel bar is mounted between the first and second side members. The peel bar has a radial portion that causes an RFID label to be separated from the surface of the web carrier as the web carrier contacts and travels over the radial portion. A cam bar is mounted on the frame and is rotatable. In a first position the cam bar causes the web carrier to contact and travel at least partially around the radial portion of the peel bar, and in a second position the cam bar prevents the web carrier from contacting and traveling at least partially around the radial portion of the peel bar.

  • Patent number: 7867859
    Abstract: Semiconductor device performance is improved via a gate structure having a tunable effective workfunction and reduced gate depletion effects. According to an example embodiment, the design threshold voltage of a semiconductor device is adjusted in a manner that includes providing a gate having a workfunction that enables operation of the semiconductor device at a selected voltage. The gate is formed having two different conductive materials with different electric workfunctions that both significantly contribute to the overall workfunction of the gate. The relative composition, thickness, and arrangement of each of the two conductive materials is selected to attain a gate electrode workfunction that is different than the workfunctions of each of the two layers and that sets the threshold voltage of the semiconductor device. The adjustability of the effective workfunction of the gate electrode can be applied to a variety of semiconductor devices.

  • Patent number: 7870610
    Abstract: Various approaches for detecting unauthorized actions on a computing platform are disclosed. In one approach, a memory region is designated as tainted if data is received from an untrusted source (such as the network) and written to that region. Thereafter, destination regions may be designated as tainted based on an operation having source and destination parameters in which at least a portion of an address range of the source overlaps an address range of a tainted memory region, and data from the source is used to update the destination. If an argument in an invocation of a function call references a tainted memory region, the call is determined to be unauthorized and data is output indicative of the unauthorized call.

  • Patent number: 7868819
    Abstract: Various systems, methods and devices are implemented for processing received signals. Consistent with one such embodiment, a method is implemented for use in a signal-communication receiver having a carrier-tracking loop and a processor for operating adaptive algorithms. The method involves interpreting a received signal using space time adaptive processing (STAP). A convergence speed of the adaptive algorithms is set based on a noise bandwidth of a phase-locked loop (PLL) in the carrier-tracking loop. A carrier-phase de-rotation constraint is implemented into weight parameters of the STAP to preserve spatial and temporal degrees of freedom in the STAP.

  • Patent number: 7818539
    Abstract: A processor implements conditional vector operations in which, for example, an input vector containing multiple operands to be used in conditional operations is divided into two or more output vectors based on a condition vector. Each output vector can then be processed at full processor efficiency without cycles wasted due to branch latency. Data to be processed are divided into two groups based on whether or not they satisfy a given condition by e.g., steering each to one of the two index vectors. Once the data have been segregated in this way, subsequent processing can be performed without conditional operations, processor cycles wasted due to branch latency, incorrect speculation or execution of unnecessary instructions due to predication. Other examples of conditional operations include combining one or more input vectors into a single output vector based on a condition vector, conditional vector switching, conditional vector combining, and conditional vector load balancing.

  • Patent number: 7808401
    Abstract: Various approaches for activating a traffic control preemption system. The traffic control preemption system has a receiver with a photodetector and circuitry that produces a number of electrical pulses in response to each detected light pulse. For each detected light pulse the number of electrical pulses represents a level of radiant power of the light pulse. A threshold number of electrical pulses and an activation frequency at which the threshold number of electrical pulses is repeated activates preemption. Control circuitry is coupled to a light emitter and controls the light emitter to emit bursts of light pulses. Each burst includes at least two light pulses and the control circuitry controls the frequency of light pulses in each burst and the frequency of the bursts to cause the receiver to produce at least the threshold number of electrical pulses at the activation frequency and activate the preemption.
