Abstract: The invention provides a sensor for determining when a latch for securing an engine cowl on an aircraft is secured by detecting the proximity of a latch hook and a latch pin. The sensor includes a resonant circuit configured and adapted to transmit a status signal when the latch is in a secured state. The sensor also includes a means for conveying status information of the latch to a location remote from the latch based on the status signal, the conveying means being operably connected to the resonant circuit. The invention also provides a method of determining when a latch is open or secured by detecting the proximity of a latch hook and a latch pin.

Abstract: A strain sensor device for measuring loads on aircraft landing gear. This is done by measuring strains in the lower end of the strut, by which we infer the loading in the entire landing gear structure. These strains can be very large (as high as 10,000 microstrain) and can be imposed in numerous random directions and levels. The present invention includes a removable sensor assembly. An electromechanical means is presented that can accommodate large strains, be firmly attached to the strut, and provide good accuracy and resolution.

Abstract: A Coriolis effect device includes a housing defining an interior chamber having a central axis, an inlet, an outlet, a leading disc and a trailing disc. Each disc is supported for oscillatory movement within the interior chamber of the housing. The leading disc defines a leading flow path in fluid communication with the inlet and interior chamber, wherein a portion of the leading flow path extends radially with respect to the central axis. The trailing disc is axially spaced from the leading disc. The trailing disc defines a trailing flow path in fluid communication with the interior chamber and the outlet, wherein a portion of the trailing flow path extends radially with respect to the central axis. A phase difference between leading and trailing oscillating signals picked up from the disc movement can be used to determine a mass flow rate of fluid passing from the inlet to the outlet.

Abstract: A microelectromechanical (MEMS) apparatus has a base and a flap with a portion coupled to the base so that the flap may move out of the plane of the base between first and second position. The base may have a cavity with largely vertical sidewalls that contact a portion of the flap when the flap is in the second position Electrodes may be placed on the vertical sidewalls and electrically isolated from the base to provide electrostatic clamping of the flap to the sidewall. The base may be made from a substrate portion of a silicon-on-insulator (SOI) wafer and the flap defined from a device layer of the SOI wafer. The flap may be connected to the base by one or more flexures such as torsional beams. An array of one or more of such structures may be used to form an optical switch.
