Abstract: A thermal energy storage system includes fluid conduits disposed in a loose solid material. The loose solid material may be disposed inside a waterproof barrier, and the fluid conduits may be configured to define a plurality of zones having different temperatures in operation. The system may include a solar collector or other source of heated oil or other fluid that is routed to the thermal energy storage unit and/or an energy-consuming facility.

Abstract: A vehicle interior trim panel comprising a mounting opening with opposing walls for slidably engaging a component into fixed relationship with the mounting opening wherein molded features in the walls of the mounting opening engage the component to align and fixedly retain the component in the mounting opening. In addition, a locking system for preventing theft is disclosed.

Abstract: A measuring gage for determining the thickness of a non-metallic material utilizes an inductive sensor positioned on one side of the material to be measured and a metallic object placed on the opposite side. The output of the sensor is used to determine the distance between the sensor and the metallic object, and hence the thickness of the material. The movement of the sensor and the metallic object can be computer controlled to map the thickness of the material along a predetermined path and produce a cross-sectional thickness profile. The output of the sensor can be used in conjunction with a computer controller responsible for adjusting the size of a score line to prepare an airbag deployment section in a vehicle trim panel.

Abstract: A fully distributed optical fiber strain sensor that makes use of the nonlinear Kerr effect and the photoelastic effect. The sensor includes a polarization maintaining optical fiber having a core region and a cladding region where the fiber is embedded within or adhered to a structural element that is to be monitored for strain. Counterpropagating optical pulses interact within the fiber such that the change in refractive index caused by the Kerr effect causes a portion of the pulse intensities to be emitted from the fiber. A strain on the fiber will cause the index of refraction of the core region to change such that a different pulse intensity is emitted from the core region. This change in the loss of pulse intensity can be used to determine the amount of strain on the structure at the interaction region. By taking a strain measurement along two polarization directions and at two different wavelengths, the direction of the strain can also be determined.
