Abstract: A method for protecting a circuit component on a semiconductor substrate from a plasma etching or other removal process includes forming a screening layer over an auxiliary layer to conceal at least an area of the auxiliary layer that overlays at least a portion of the circuit component, such as for example a high-ohmic poly resistor. The method transfers a pattern defined by a mask onto the screening layer by selectively removing portions of the screening layer in accordance with the pattern. Portions of the auxiliary layer that are not protected by the screening layer are removed using a plasma gas selective to the auxiliary layer material, without removing the area of the auxiliary layer that overlays the portion of the circuit component, thereby protecting the circuit component from the plasma gas via the screening layer and auxiliary layer.

Abstract: A first device transmits data over a first branch of a communications link toward a second device. That second device loops the received data pattern back over a second branch of the communications link. A bit error rate of the looped back data pattern is determined and a pre-emphasis applied to the transmitted data pattern is adjusted in response thereto. The first device further perturbs the data pattern communications signal so as to increase the bit error rate. The pre-emphasis is adjusted so as to reduce the determined bit error rate in the looped back data pattern in the presence of the perturbation. The steps for perturbing the signal and adjusting the pre-emphasis are iteratively performed, with the perturbation of the signal increasing with each iteration and adjustment of the pre-emphasis being refined with each iteration. The signal is perturbing by injecting modulation jitter into the signal (increasing each iteration) and adjusting amplitude of the signal (decreasing each iteration).

Abstract: A circuit includes a memory cell having a high voltage supply node and a low voltage supply node. Power multiplexing circuitry is included to selectively apply one of a first set of voltages and a second set of voltages to the high and low voltage supply nodes of the cell in dependence upon a current operational mode of the cell. If the cell is in active read or write mode, then the multiplexing circuitry selectively applies the first set of voltages to the high and low voltage supply nodes. Conversely, if the cell is in standby no-read or no-write mode, then the multiplexing circuitry selectively applies the second set of voltages to the high and low voltage supply nodes. The second set of voltages are offset from the first set of voltages. More particularly, a low voltage in the second set of voltages is higher than a low voltage in the first set of voltages, and wherein a high voltage in the second set of voltages is less than a high voltage in the first set of voltages. The cell can be a member of an array of cells, in which case the selective application of voltages applies to the array depending on the active/standby mode of the array. The array can include a block or section within an overall memory device including many blocks or sections, in which case the selective application of voltages applies to individual blocks/sections depending on the active/standby mode of the block/section itself.

Abstract: A protocol for collision avoidance in inter and intra basic service set broadcast/multicast communication in a wireless network is disclosed. An access point reserves a broadcast transmission time and conveys that reservation to each of its associated stations. Using a beacon or an action frame, the transmission reservation time is sent to all stations and other neighboring access points within range of the primary access point. Upon receiving the broadcast transmission time reservation, each station associated with the reserving access point and any neighboring access points set their network allocation vector thus preventing frame transmission or reception during the now reserved transmission time.

Abstract: A fuel cell device includes a housing containing a fuel processor that generates fuel gas and a fuel cell having electrodes forming an anode and cathode, and an ion exchange electrolyte positioned between the electrodes. The housing can be formed as first and second cylindrically configured outer shell sections that form a battery cell that is configured similar to a commercially available battery cell. A thermal-capillary pump can be operative with the electrodes and an ion exchange electrolyte, and operatively connected to the fuel processor. The electrodes are configured such that heat generated between the electrodes forces water to any cooler edges of the electrodes and is pumped by capillary action back to the fuel processor to supply water for producing hydrogen gas. The electrodes can be formed on a silicon substrate that includes a flow divider with at least one fuel gas input channel that can be controlled by a MEMS valve.

Abstract: A protocol for inter-cell communication in a cognitive radio wireless access network using beacon period framing is disclosed. By establishing scheduled use of beacon periods within each frame of a super-frame among a plurality of participating cells in a wireless access network, efficient and reliable communication can take place eliminating beacon packet collisions and bandwidth wastage. Within each super-frame exits 16 data frames of fixed size which can each include both a data transmission portion and a beacon period. A protocol is established by which announcement, reserved, and free-to-use beacon periods are established within the super-frames associated with a particular spectrum. By coordinating communication between cells on the beacon period, collision between cells by simultaneous attempts to transmit or bandwidth wastage of periods in which no transmission takes place can be avoided.

Abstract: The invention relates to a data modulation method applicable to make data streams tend to have desired properties, useful for clock recovery, making signals more distinguishable, or enforcing run-length conditions. A stream of input data and a corresponding stream of output data are grouped into elements of a finite field. Input elements of said input data are modified by a transform generating output elements of the output data, such that a current output element is a linear combination of a current input element and at least one previous output element. A multiplier applied to at least one previous output element is a non-zero and non-unity element of the finite field. A set of initial conditions inherent to the transform, is selected such that the output elements resulting from the transform tend to have the desired property.
