    摘要: An apparatus that is comprised of a controller, a digital-to-analog converter (DAC), a temperature sensor, an analog-to-digital converter (ADC), and a voltage controlled oscillator (VCO). The controller to reads temperature data proportional to a temperature of the VCO, reads previously-calculated calibration data based on the read temperature data, determines a frequency command signal based on the read previously-calculated calibration data, and outputs the frequency command signal. The DAC converts the frequency command signal into a frequency analog signal. The temperature sensor produces the temperature signal. The ADC converts the temperature signal into the temperature data. The VCO produces an output frequency based on the frequency analog signal.

    摘要: A test system 100 that can accept a plurality of plug-in electronic cards in Xi Slots 126 or PXI slots 134 is described. The test or source measure switching system 100 includes a sequencer or sequence engine 130 which is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequencer 130 is sequential and deterministic to approximately ten microsecond resolution.

    摘要: A lock system for casement windows is disclosed which includes a tie bar slidably secured to the flame. The tie bat is secured to a lock handle that is also secured to the flame. The tie bat eliminates the need for rollers riveted to the tie bar by having a first bent section disposed between straight sections and a second bent section disposed between straight sections. All of the straight sections are linearly aligned with one another and at least some of the straight sections of the tie bar are slidably mounted to the flame using conventional guides. The lock system also includes first and second strikers mounted to the sash. The first striker comprising a first ramp that receives a first bent section and the second striker comprising a second ramp that receives a second bent section when the tie bat is slidably moved towards the first and second strikers as the tie bar is moved from an unlocked position to a locked position. Movement of the first and second bent sections along the first and second ramps respectively as the tie bar moves towards the locked position results in the sash and frame being pulled together. A third bent section may be included towards the middle of the tie bar and used to couple the tie bar to the lock handle or actuator.

    摘要: An HVAC&R system is disclosed that utilizes energy-efficient valving. The valving controls the flow of refrigerant and may be adapted for evaporator or condenser applications, on both AC systems and heat pumps (as well as chillers and other refrigeration systems). The valving may provide simultaneous and individualized control of flow through individual coils or groups of coils for improved control of evaporation, condensation, defrosting and so forth. In some configurations a common sensor may be shared between individual coils or groups of coils and may provide sensed parameters to control circuitry for controlling the valving. Other configurations may include bypass valving to direct fluid around the flow control valving. In yet other configurations, a valve may be used to bypass tapped vapor around a heat exchanger functioning as an evaporator.

The test or source measure switching system 100 includes a sequencer or sequence engine 130 which is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequencer 130 is sequential and deterministic to approximately 10 microsecond resolution. The sequencer 130 includes a trigger router which can be a fully configurable trigger input and trigger output routing matrix. Every trigger input can be configured via several detection modes such as active high, active low, level high and level low. Also, trigger outputs can be configured to be triggered on single, multiple or auto triggers if set.
