Disclosed are embodiments of apparatus, methods, and systems for inflatable curtain venting. In one embodiment, an inflatable curtain airbag is tested using a 50th-percentile dummy. The inflatable curtain airbag comprises a vent opening positioned such that during the crash test, the head of the 50th-percentile dummy strikes the airbag at the location of the vent such that the exit of inflation gas through the vent is at least partially blocked. The same inflatable curtain airbag may then be used in a test involving a 5th-percentile dummy, in which case the head of the 5th-percentile dummy would not strike the airbag so as to block the vent, thereby allowing for venting of the airbag.

A cartridge for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.

The present invention provides a cartridge for analyzing a fluid sample. The cartridge provides for the efficient separation of cells or viruses in the sample from the remaining sample fluid, lysis of the cells or viruses to release the analyte (e.g., nucleic acid) therefrom, and optionally chemical reaction and/or detection of the analyte. The cartridge is useful in a variety of diagnostic, life science research, environmental, or forensic applications for determining the presence or absence of one or more analytes in a sample.

A mounting system and method of attaching an a side impact curtain airbag to a vehicle is provided that is inexpensive, simple to use, and does not require fasteners or other connectors. The mounting system includes one or more airbag mounts comprising a plate that has been positioned within the vehicle. The plate may a separate structure that may be attached to a vehicle as a well as a surface of the vehicle's body to which an airbag may be attached. Preferably, the plate includes one or more first tabs and one or more second tabs which are configured to define a receiving area in the plate. The first and second tabs are also configured such that the second tabs are inverted relative to the first tabs. An airbag with one or more slits and a hemmed portion may also be added to the mounting system. The mounting system operates to attach the curtain airbag by having the first and second tabs configured such that the airbag engages the first and second tabs so as to bind a portion of the airbag's hemmed portion within the receiving area formed into the plate.

The present invention discloses a method and apparatus for testing the operational capability of flexure area equipped sensors especially those made of micromachined silicon. A thermal actuator beam is provided to bridge the structures which are joined by the flexure area. During the test, the beam's temperature is changed relative to that of the flexure area so as to provide a differential expansion or contraction. The result is that the flexure area bends and conventional bending sensors for the flexure area can sense the amount of bend. By comparing the actual amount of bend sensed with the amount expected from the temperature change applied to the beam, the operational capability can be determined.

By using a hot melt adhesive sheet a fabric is adhered to at least one side of an air cell sheet of polyethylene after radiation with .beta.- or .gamma.-rays. The material combines great strength and flexibility with good thermal insulating ability and low weight together with great and permanent buoyancy in water.

This disclosure provides implementations of electromechanical systems resonator structures, devices, apparatus, systems, and related processes. In one aspect, a sacrificial layer is deposited on an insulating substrate. A lower electrode layer is formed proximate the sacrificial layer. A piezoelectric layer is deposited on the lower electrode layer. An upper electrode layer is formed on the piezoelectric layer. At least a portion of the sacrificial layer is removed to define a cavity such that at least a portion of the lower electrode layer is spaced apart from the insulating substrate.

A tool support adjusts the level of, for example, a tool mounted behind the work surface of a plate so as to vary how far the tool working implement extends through and beyond the work surface. The tool support includes a plurality of threaded rods fixed at one end to the plate, a carriage mounted to the threaded rods and holding the tool, a drive rod and a gear train. Rotation of the drive rod effects, through the gear train, translation of the carriage along the threaded rods, thus advancing or withdrawing the tool working implement through an aperture in the plate. A distance gauge informs an operator how far beyond the work surface the working implement protrudes or how far the carriage has traveled. Other embodiments include a drive motor, various gear train configurations involving posts and gear racks, and translating the carriage within a cylinder.
