Abstract: This invention relates to cognitive radio based wireless communications of dynamic spectrum access networks, and in particular to a method of addressing zero-delay frequency switching for cognitive dynamic frequency hopping. The method combines regular (periodic) channel maintenance with dynamic frequency hopping over a cluster of vacated channels that are initially setup such that the switching delays for channel setup and channel availability check are eliminated.

Abstract: A single-stage integrated circuit drives LED sources in a constant power mode to eliminate the need for LED current sensing, while reshaping the waveform of the inductor current near line zero crossing to achieve high power factor. The integrated circuit achieves substantially constant input power by maintaining a constant voltage at a power factor corrector controller through an input voltage feedforward system. Accordingly, the disclosed circuit provides a high power factor, high efficiency, simple, and cost-effective solution with substantially consistent input power for both isolated and non-isolated offline LED applications.

Abstract: Fair usage of working channels in a wireless network is disclosed. A base station associated with a cell within a wireless community monitors the congestion of the working channel of neighboring communities. Upon determining that the congestion of the working channel of a neighboring community is less than that of its existing working channel, the base station initiates a switch to the neighboring community's working channel. Upon joining the new community, the frame structure and other networking parameters and attributes are adjusted.

Abstract: The presence of a child within an enclosed space in an appliance, such as a washing machine, dishwasher or refrigerator, is detected using one or more MEMS sensors positioned to detect movement within the enclosed space through various measured characteristics. In preference, combinations of different types of MEMS sensors are utilized to detect the movement. Movement may be attributed to the presence of a child inside the enclosed space, rather than resulting from other influences, with increased reliability if the determination is made based upon such combinations of different characteristics. Safety processes may be initiated upon detecting the presence of the child.

Abstract: A trimmable resistor for use in an integrated circuit is trimmed using a heater. The heater is selectively coupled to a voltage source. The application of voltage to the heater causes the heater temperature to increase and produce heat. The heat permeates through a thermal separator to the trimmable resistor. The resistance of the trimmable resistor is permanently increased or decreased when the temperature of the resistor is increased to a value within a particular range of temperatures.

Abstract: A method and integrated circuit for preserving a battery's charge and protecting electrical devices is disclosed. A maximum and a minimum battery voltage value at the output port are stored in a memory. A steady state battery voltage at the output port is measured and stored in the memory. A processor compares the measured steady battery voltage value to the maximum and the minimum battery voltage values. If the measured steady state battery voltage value is greater than the maximum battery voltage value, an over voltage state is reported by the processor. If the measured steady state battery voltage value is less than the minimum battery voltage value, a low battery voltage state is reported by the processor.
