摘要： An improved pressure transducer is disclosed. The transducer includes a connector, an enclosure, a sensor portion, and an external heater disposed to heat the sensor portion. In some aspects, the sensor portion includes a sensor constructed from a brittle material and does not employ any fill fluid within the sensor. In another aspect, the invention includes a kit that adapts non-heated high purity vacuum transducers for heated use. The kit includes a connector portion and a heater portion that is coupled to the connector portion. The connector portion may also include one or more indicators.

摘要： Vibration-based electrical power generation is provided. In one aspect, a vibration-based power generator is embodied within a machine dampener and includes an electromotive power generation module and a piezoelectric power generation module. A power storage device is operably coupled to the electromotive power generation module and the piezoelectric power generation module. In another aspect, a device for generating electrical energy based is provided. The device includes a housing operably coupleable to a source of vibration. The housing defines a chamber inside. A first circular permanent magnet is located within the chamber and has an outer diameter. A ring-type permanent magnet is located around the first circular permanent magnet and defines an annular space therebetween. At least one voice coil portion is located in the annular space and is coupled to a flexure structure to allow the voice coil portion(s) to move within the flux of the permanent magnets in response to vibration.

摘要： A barometric pressure sensor including a base layer, a sensor layer and a reference layer. The base layer has a passageway between a pressure inlet and a mounting face. The sensor layer is bonded by an insulating bond to the mounting face and includes a conductive diaphragm. The reference layer is mounted on the sensor layer to form a reference vacuum cavity. The reference layer includes a conducting surface facing the conductive diaphragm across the reference vacuum cavity to form a pressure sensing capacitor.
