Abstract:
The present disclosure is generally directed to a strain sensor, system and method of fabrication and use that includes an optical fiber, an optical signal generator that transmits an optical signal through the optical fiber, at least two photonic crystal slabs within the optical fiber separated by a first segment of optical fiber, a photo-detector that detects a reflected optical signal from the at least two photonic crystal slabs, and a processor that computes a mechanical strain over the first segment of optical fiber based on the reflected optical signal detected by the photo-detector.
Abstract:
A system may include a spherical retroreflector that reflects incident light back in substantially the same direction as a light source; and a surface of the spherical retroreflector including a light modulator that modulates incident light from the light source in response to a stimulus and reflects a modulated light, wherein the light modulator is a variably reflecting backing of the spherical retroreflector.
Abstract:
A cable connector assembly includes a module retainer and a set of two or more cable insert modules sized and shaped for removable retention within two or more module slots of the module retainer. A cable insert module of the set of two or more cable insert modules includes a cable insertion recess sized and shaped for insertion of a cable wire of a cable, a connectivity interface on an opposing face of the cable insert module, and a transmission path between the cable insertion recess and the connectivity interface.
Abstract:
A ventilation assembly comprises a number of fan systems configured to purify air and a number of air distribution assemblies. Each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of a passenger seat. Each air distribution assembly of the number of air distribution assemblies comprises a pair of air distribution vents, ductwork configured to receive air from at least one fan system of the number of fan systems and direct air to the pair of air distribution vents, and a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback for providing purified air to a seated passenger.
Abstract:
An electrical contact system includes a contact having a barrel with a wire entry portion having a first diameter, a clip portion having a second diameter, and a cam portion having a second diameter at a first end that tapers to a third diameter at a second end near the wire entry portion. The system also includes a clip positioned in the clip portion of the barrel, wherein ends of inwardly directed tines of the clip are configured to engage the conductor to enable the clip to be drawn onto the cam portion in response to a user pulling the wire after insertion of the conductor through the clip.
Abstract:
A retaining fixture for attachment to a wire-harness board comprises a base, a first arm, a second arm, a first gripping member, and a second gripping member. The first arm extends from the base. The second arm extends from the base. The first gripping member is coupled to the first arm and comprises a first-gripping-member surface that is convex toward the second arm. The second gripping member is coupled to the second arm and comprises a second-gripping-member surface that is convex toward the first arm. The first gripping member and the second gripping member are resiliently deformable.
Abstract:
A method and system are provided to position and drill an opening for a fastener through one or more workpieces. In the context of a method, a peen mark is formed on a workpiece at a location at which the opening is to be drilled. The method also includes utilizing a robotic vision system to identify the peen mark on the workpiece and thereafter drilling the opening configured to receive the fastener at the location designated by the peen mark. In the context of a system, the system includes a dot peen marking system configured to form a peen mark on a workpiece at a location at which the opening is to be drilled. The system also includes a robot comprising a vision system configured to identify the peen mark on the workpiece and a drilling machine configured to drill the opening at the location designated by the peen mark.
