Abstract: An apparatus and a system, as well as a method and article, may operate to independently adjust a plurality of processor clocks coupled to a corresponding plurality of networked processors responsive to one or more status indicators to provide scalable performance and power consumption. The status indicators may indicate the status of routers coupled to the processors. Additional apparatus, systems, and methods are disclosed.

Abstract: Briefly, in accordance with one embodiment of the invention, an orthogonal frequency division multiplexing system may provide a dynamically calculated cyclic extension, the length of which may be based at least in part on a delay spread due to an experienced environmental condition. The length of the cyclic extension may be calculated by determining a channel impulse response, and then computing the energy distribution of the channel impulse response. The length of the cyclic extension may then be set according to the energy distribution of the channel impulse response.

Abstract: Described herein are antennae that may provide a relatively compact design that has resonances at UHF (700 MHz), L-band (1.6 GHz), and S-band (2 GHz) to allow good performance in all of these bands. Normally television antennas are relatively large and on the order of a foot long or more due to the long wavelengths of the VHF/UHF band, however the antennae described herein may be relatively small.

Abstract: An apparatus and a system, as well as a method and article, may operate to search for a benefit associated with switching from receiving first information from a first network to receiving second information from a second network, and downloading a demodulation code to demodulate the second information received from the second network.

Abstract: A micro-coded accelerator may comprise multiple programmable control units, multiple special function units, a cross-bar switch to connect any of the control units to any one or more of the special function units, and a global memory to facilitate processing by these units. Each control unit may have an array of programmable logic arrays (ARPLAs), each of which may be configured in various ways, a local memory, and a switch circuit to enable the components of the control unit to perform various operations. By configuring the ARPLAs, the control units' internal switch circuitry, and the cross-bar switch, the micro-coded accelerator may be dynamically reconfigured to perform multiple types of operations.
