摘要： The invention relates to thin silicon membranes formed in layers of silicon such as are normally utilized as substrates in the manufacture of integrated electronic circuits. The thin membranes constructed in accordance with the invention are capable of deformation by electrostatic forces and are applicable to a wide range of uses including the manufacture of solid state pressure sensors, resonant, and antenna structures, as well as electro-optical display elements. A processing technique is disclosed which is particularly adapted to forming membranes in silicon substrates in a manner which is compatible with the construction thereon of other integrated circuit components.

摘要： Device for visual indication of a maximum fluid pressure condition reached during a given interval of time. Useful for the in-flight recording of fluid pressure condition e.g., in the reduction gear box of a jet engine where excessive pressures are indicative of incipient failures, the device comprises a body having a cavity in fluid pressure communication with system fluid, an indicator movable relative to the body cavity in response to changes in system fluid pressure, and locking means limiting indicator travel to a single direction indicative of a relatively higher pressure condition in the system.

摘要： A pressure measurement system includes a pressure pod with two chambers separated by a diaphragm such that a deformation/movement of the diaphragm is indicative of a difference between the pressures of the two chambers. Such deformation/movement is detected by a device that has no physical contact with the diaphragm, for example, by an optical detector that detects a change in the shape of the diaphragm or a movement of a protrusion on the diaphragm.

摘要： A system for measuring and indicating pressure that uses as its pressure sensing element an outer resilient tube, an inner resilient tube, and a rolling diaphragm connecting the inner and outer tubes, and held inside a protective enshrouding structure where pressure applied to the annulus between the tubes causes the diaphragm to deform and roll to axial extend the outer tube by an amount proportional to the applied pressure. The structure has features that enable visual correlation of the partially rolled tube's unrolled state with the applied pressure. The system can be incorporated into a syringe to create a pressure measuring syringe for inflating endotracheal cuffs while providing a reading of the cuff pressure
