摘要:
Pressure sensors having components with reduced variations due to stresses caused by various layers and components that are included in the manufacturing process. In one example, a first stress in a first direction causes a variation in a component. A second stress in a second direction is applied, thereby reducing the variation in the component. The first and second stresses may be caused by a polysilicon layer, while the component may be a resistor in a Wheatstone bridge.

A non-contacting rotary joint for transmitting an input signal guided within an input optical waveguide has an electrical transmission line and a probe. The transmission line has an even number N≧4 of equal length transmission line segments. The optical waveguide is connected to an optical distribution network which has an optical power splitter for splitting the input signal into N or N/2 individual signals of equal optical power. These signals are forwarded to opto-electrical converters to generate electrical signals for driving the electrical transmission line. The lengths of the optical transmission lines are adjusted so that the propagation time of the optical signal from the end of the input optical waveguide to the end of each individual optical transmission line is approximately the same.

An EMI filtered terminal assembly includes at least one conductive terminal pin, a feedthrough capacitor, and a counter-bore associated with a passageway through the capacitor and the lead wire. Preferably, the feedthrough capacitor having counter-drilled holes on its top side is first bonded to a hermetic insulator. The counter-bore in the capacitor provides greater volume for the electro-mechanical attachment between the capacitor and the lead wire, permitting robotic dispensing of, for example, thermal-setting conductive adhesive.

The variable capacitor (1) is characterized by the fact that the safety end switches (6, 7) as well as a displacement detector (10) are integrated in the housing (1) or in an additional housing (5) provided at one of the front ends of the capacitor housing (1). Due to this construction, the entire device becomes more compact and more precise in operation.
