A method and system are disclosed that can be applied to achieve high-throughput in a WLAN. Central to the present invention is the use of an SDMA compatible multi-beam antenna system by a WLAN access point. A system based on two types of antennas-dynamic beam forming and fixed beam antennas—is described. A mechanism and protocol are described that implement simultaneous transmissions with respect to an SDMA compatible access point and thereby improve spectral efficiency, and by extension achieve higher throughput. Based on the recognition that current WLAN MAC has major limitations in throughput, certain MAC extensions (that can be applied independently of SDMA) are described. Also disclosed are power-saving and power control techniques that improve battery performance and contribute to a reduction in station size, and a means of reducing channel interference. The present invention also deals with the problem of backward compatibility with conventional devices that implement the protocol that is a subset covered by the present invention.

An external transmitter circuit drives an implantable neural stimulator having an implanted coil from a primary coil driven by a power amplifier. For efficient power consumption, the transmitter output circuit (which includes the primary coil driven by the power amplifier inductively coupled with the implanted coil) operates as a tuned resonant circuit. When operating as a tuned resonant circuit, it is difficult to modulate the carrier signal with data having sharp rise and fall times without using a high power modulation amplifier. Sharp rise and fall times are needed in order to ensure reliable data transmission. To overcome this difficulty, the present invention includes an output switch that selectively inserts a resistor in the transmitter output coil circuit in order to de-tune the resonant circuit only during those times when data modulation is needed. Such de-tuning allows sharp rise and fall times in the data modulation without the need for using a high power modulation amplifier. Because data modulation is typically needed for only a small percent of the time that a carrier signal is present, it is thus possible using the present invention to achieve reliable data modulation, transmission and reception without having to use a high power modulation amplifier in the transmitter.

A technique for caching coverage information for edges that are shared between adjacent graphics primitives may reduce the number of times a shared edge is rasterized. Consequently, power consumed during rasterization may be reduced. During rasterization of a first graphics primitive coverage information is generated that (1) indicates cells within a sampling grid that are entirely outside an edge of the first graphics primitive and (2) indicates cells within the sampling grid that are intersected by the edge and are only partially covered by the first graphics primitive. The coverage information for the edge is stored in a cache. When a second graphics primitive is rasterized that shares the edge with the first graphics primitive, the coverage information is read from the cache instead of being recomputed.

The present invention is a method and apparatus for providing a pseudo random sequence for a spread spectrum system that prevents interception and provides real estate and power consumption efficiency.

The location of the channel, or the actual frequency of the channel, could be associated with a particular pseudo random sequence to create a hop set for frequency hopping. Additionally, the location of a characteristic of the spread spectrum system, such as a noise characteristic, could be utilized to determine a content of a pseudo random sequence.

To provide a memory element which keeps a stored logic state even without supply of power. To increase an effect of reducing power consumption by facilitating stop of supply of power to the memory element for a short time. Data (potential) held in a node in a logic circuit can be swiftly saved on a node where one of a source and a drain of the transistor and one electrode of the capacitor included in a memory circuit are connected by lowering a potential of the other electrode of a capacitor before a transistor is turned on. By making a potential of the other electrode of the capacitor when the transistor is in an off state higher than a potential of the other electrode of the capacitor when the transistor is in an on state, a potential of the node can be reliably held even without supply of power.

Provided is a method of reducing power consumption of an optical access network (OAN) as much as possible by configuring an optical line terminal (OLT) and optical network terminals (ONTs) in the OAN to support a maximum power-saving mode. According to the method, upon the application of power, an ONT operates normally in an activation mode. The ONT then determines whether the requirements for switching from activation mode to power-saving mode are satisfied. If the requirements are satisfied, the ONT transmits a sleep signal to an OLT, which is a message notifying that the ONT will soon switch to power-saving mode. Thereafter, the ONT switches to power-saving mode and cuts off power for all functions except for power for monitoring and controlling external inputs. The ONT then determines whether the requirements for switching from power-saving mode to activation mode are satisfied. If the requirements are satisfied, the ONT transmits a wake-up signal to the OLT and switches to the activation mode for normal operation.
