Abstract: Disclosed is a laser apparatus. The apparatus includes a frequency multiplier to multiply a first frequency of laser radiation to a second frequency, the frequency multiplier having a temperature that can vary over a temperature range, and a controller to control the temperature of the frequency multiplier to regulate the level of laser radiation exiting the frequency multiplier.

Abstract: A system provides protection against erroneous updating of a memory device by generating control signals to transfer data from a processor to the memory device where a write protect signal is provided at an interrupt input of the processor.

Abstract: In accordance with one embodiment of a method and apparatus for testing a temperature sensor, an apparatus includes at least one component that affects ambient temperature. The at least one component is positioned on a circuit board so that when a current is applied to the at least one component the temperature of a temperature sensor is affected, where the temperature sensor is attached to a battery in contact with the circuit board. The response of the temperature sensor further includes the capability to be measured by external equipment. In accordance with another embodiment of a method and apparatus for testing a temperature sensor, a method of testing a temperature sensor attached to a battery, the battery being in contact with a circuit board, is as follows. The response to a temperature sensor is measured. Current is applied to the at least one heating component with sufficient proximity of the temperature sensor to affect its temperature.
