摘要： A system and method of testing switch functionality of a tunable capacitor array is disclosed. A built in test (BIT) circuit provides digital device for testing the functionality of a programmable switch capacitor array circuit. The method and system provides for switching a capacitor switch of a switch capacitor array between on and off, switching a test enable switch of a BIT circuit between on and off, pulling an internal node of the BIT circuit either high or low using a current source, and determining whether the internal node has been pulled either high or low. In addition, the method and system provides for making a pass or fail determination based on a determined state of the internal node.

摘要： This is a multi-cylinder engine with a main piston and an auxiliary piston in each cylinder. The main piston is operated by means of compressed gas as a propellant. The auxiliary piston is operated by a hydraulic system controlled by movement of the main piston, and by a valve in the hydraulic system also controlled by movement of said main piston. The engine can have four engine cylinders. Compressed gas is sequentially applied to the cylinders for about 90.degree. rotation of the crank shaft for each cylinder. The angular degree of rotation of the crank shaft during which compression gas is delivered to the individual cylinders can be varied while the engine keeps operating. Liquid gas vaporizes to gaseous state for use in the engine.

摘要： A crystal oscillator circuit which does not produce runt pulses when the oscillator is turned on or off. The circuit includes a crystal oscillator, an integrator which integrates the energy in a plurality of pulses, a threshold circuit which is active when the output of the integrator reaches a pre-specified threshold and gating circuits which gate the output of the crystal oscillator to the output terminal only when the threshold circuit has reached the specified threshold.
