Abstract:
An apparatus for cutting a cutting a payload strap includes a cutting assembly with an aperture to enclose a payload strap and a cutting element to sever the payload strap, a non-explosive energy source to store cutting energy, a control component coupled to the energy source to release the cutting energy, and a controller coupled to the control component to time and control the delivery of the cutting energy to the cutting element.
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 method for automated cable wire processing includes receiving a set of two or more cable wires, including at least a first cable wire positioned at a selection position, and a second cable wire positioned away from the selection position. A cable selection tool is automatically moved to contact the set of two or more cable wires, such that contact between the cable selection tool and the first cable wire causes a tip portion of the first cable wire to extend into a working region, and contact between the cable selection tool and the second cable wire moves a tip portion of the second cable wire outside of the working region. One or more tip processing operations are applied to the tip portion of the first cable wire within the working region.
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.
Abstract:
A thermal management system includes a first hydraulic system for circulating a first hydraulic fluid at a first temperature and a second hydraulic system for circulating a second hydraulic fluid at a second temperature that is higher than the first temperature. The thermal management system also includes a sealed heat transfer device coupled between the first hydraulic system and the second hydraulic system. The sealed heat transfer device is not in flow communication with either of the first hydraulic system and the second hydraulic system. The sealed heat transfer device is configured to transfer heat from the second hydraulic fluid to the first hydraulic fluid.
