Abstract: A circuit board, which includes one or more sensors, is integrated in a fluid control device, such as a valve manifold and a base plate. The fluid control device selectively directs a fluid used to control pneumatic or hydraulic equipment. The sensors are used to measure physical characteristics of the fluid, such as flow rate, pressure, and temperature. A flow sensor includes a paddle and a support member. The paddle is disposed at least partially in an orifice and is displaced in response to fluid flow. The support member positions the paddle in the orifice and includes a plurality of strain gauges. The strain gauges are disposed on only one side of the support member and are mechanically stressed in response to the paddle being displaced by the fluid flow.

Abstract: An ultrananocrystalline diamond (UNCD) element formed in a cantilever configuration is used in a highly sensitive, ultra-small sensor for measuring acceleration, shock, vibration and static pressure over a wide dynamic range. The cantilever UNCD element may be used in combination with a single anode, with measurements made either optically or by capacitance. In another embodiment, the cantilever UNCD element is disposed between two anodes, with DC voltages applied to the two anodes. With a small AC modulated voltage applied to the UNCD cantilever element and because of the symmetry of the applied voltage and the anode-cathode gap distance in the Fowler-Nordheim equation, any change in the anode voltage ratio V1/N2 required to maintain a specified current ratio precisely matches any displacement of the UNCD cantilever element from equilibrium. By measuring changes in the anode voltage ratio required to maintain a specified current ratio, the deflection of the UNCD cantilever can be precisely determined. By appropriately modulating the voltages applied between the UNCD cantilever and the two anodes, or limit electrodes, precise independent measurements of pressure, uniaxial acceleration, vibration and shock can be made. This invention also contemplates a method for fabricating the cantilever UNCD structure for the sensor.

Abstract: There is provided a measuring device (dial gauge) capable of performing measurement with a desired measuring force regardless of the posture of the measuring device.
A dial gauge in an exemplary embodiment of the present invention includes a measuring force adjustment unit provided to a body case and capable of moving and being positioned and fixed in a direction substantially parallel to a moving direction of a spindle.
A biasing means has one end directly or indirectly engaged with the spindle and the other end directly or indirectly engaged with the measuring force adjustment unit, and biases the spindle toward a tip end.
The measuring force adjustment unit includes an external thread portion and a connection supporting member having one end screwed with the external thread portion and the other end coupled to the biasing means. The connection supporting member is screw-fed by rotationally operating the external thread portion in such a manner that a position of the connection supporting member is changed and fixed.

Abstract: A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.
