Abstract:
An apparatus and a system, as well as a method and article, may operate to receive a request associated with a specification at a first access point, and to locate a second access point capable of supporting the specification. A handoff from the first access point to the second access point may be affected.
Abstract:
A communication station performs closed-loop transmit power control and adjusts its transmit power level based on an access pint sensitivity, a path loss and/or link margin variation. An average received power level of orthogonal frequency-division multiplexed (OFDM) subcarriers of an OFDM channel may be measured at the communication station, and the path loss may be estimated from an access point transmit power level and the measured power level. The communication station may request an access point’s transmit power level and link margin from the access point prior to estimating the path loss. The communication station may calculate the access point sensitivity by subtracting path loss and the access point link margin from the communication station’s transmit power level. The link margin variation may be estimated from an access point transmit power variation, an indoor path loss variation, and/or a receiver power measurement error of the communication station.
Abstract:
Described is an apparatus comprising a transimpedance amplifier to receive an input current from a photodiode and provide an output voltage at first and second differential output terminals. A receive signal strength indicator may generate a differential receive signal strength indication (RSSI) signal based, at least in part, upon a voltage across the first and second differential output terminals.

Abstract:
A method is described for improving the exposure focus for modern steppers used in the lithography of semiconductor substrates such as wafers. A wafer is sawed from a semiconductor ingot in a particular direction relative to a reference point on the ingot. As a result of the sawing, a series of raised and recessed formations manifest on the surface of the wafer. After various layers have been added to the wafer and the photoresist layer is ready to be removed, the wafer is aligned with the stepper so that a dynamic focus area of the stepper is aligned with the formations and/or the sawing direction. Such alignment improves the critical dimension control and reduces variability in printing small geometry features during lithography, resulting in higher yields.
Abstract:
Embodiments of a system and method for enhanced graphics rendering performance in a hybrid computer system are generally described herein. In some embodiments, a graphical element in a frame, application, or web page, which is to be presented to a user via a web browser, is rendered either by a first processor or a second processor based on indications of whether the first or the second processor is equipped or configured to provide faster rendering. A rendering engine may utilize either processor based on historical or anticipated rendering performance, and may dynamically switch between the hardware decoder and general purpose processor to achieve rendering time performance improvement. Switches between processors may be limited to a fixed number switches or switching frequency.

High voltage three-dimensional devices having dielectric liners and methods of forming high voltage three-dimensional devices having dielectric liners are described. For example, a semiconductor structure includes a first fin active region and a second fin active region disposed above a substrate. A first gate structure is disposed above a top surface of, and along sidewalls of, the first fin active region. The first gate structure includes a first gate dielectric, a first gate electrode, and first spacers. The first gate dielectric is composed of a first dielectric layer disposed on the first fin active region and along sidewalls of the first spacers, and a second, different, dielectric layer disposed on the first dielectric layer and along sidewalls of the first spacers. The semiconductor structure also includes a second gate structure disposed above a top surface of, and along sidewalls of, the second fin active region. The second gate structure includes a second gate dielectric, a second gate electrode, and second spacers. The second gate dielectric is composed of the second dielectric layer disposed on the second fin active region and along sidewalls of the second spacers.

Abstract:
A hot-pluggable docking station may include one or more central processing units (CPUs) and internal memory and other supporting circuitry within the dock. When a lower performance device is docked it may utilize this additional computing power as well as any of the peripherals connected to the dock thus enhancing the computing abilities of the lower performance device. In addition, the smart docking station may be networked or otherwise connected to other such smart docks each acting as a node in a distributed computing network and their computing ability may be available and shared with the network.
