Abstract: A tire pressure monitoring apparatus (10) includes a pressure transducer (14) and a valve stem (12). A support bracket (50) connects the valve stem (12) to the pressure transducer (14) and facilitates pivotal movement between the valve stem and the pressure transducer. The support bracket (50) includes a valve stem biasing member (80) that exerts a spring bias on the valve stem (12) to help maintain a selected angular position of the valve stem relative to the pressure transducer (14).

Abstract: A tire pressure mounting apparatus is provided including a pressure sensor for sensing the pressure in a tire. The pressure sensor has a housing. A threaded fastener is secured to the housing and forms a first valve portion. A tire valve stem projects through a first opening in a rim for holding the tire. The tire valve stem carries a second valve portion therein. The first valve portion and the second valve portion form a valve when screwed together.

Abstract: An apparatus (10) includes a battery (12) that has a positive terminal (50) and a negative terminal (52). At least one layer of electrical insulating material (60) is disposed on one of the positive terminal (50) and the negative terminal (52). At least one electrically conductive circuit layer (62) is disposed on the at least one layer of electrical insulating material (60).

Abstract: A system and method for aligning video images with an underlying visual field are provided. A video camera is coupled with a heads up display, and a computer positions images from the video camera on the heads up display based on the relative orientations of the camera and the display. As the video camera moves with respect to the display, the images are repositioned within the heads up display. The video image, which may, for example, come from a weapon sight, is aligned within the heads up display so that an observer can easily view the camera image without having to shift focus from the larger scene.

Abstract: An earth retaining wall having at least a pair of tiers of side-by-side blocks which define a receiving channel for a connector bar with spaced-apart keys that engage apertures in a lattice-like grid extending laterally from the tiers, the grid being covered by backfill for interlocking the backfill with the retaining wall, the keys distributing the load of the backfill evenly across the wall.
