Abstract: This document describes techniques and apparatuses for a plastic air-waveguide antenna with conductive particles. The described antenna includes an antenna body made from a resin embedded with conductive particles, a surface of the antenna body that includes a resin layer with no or fewer conductive particles, and a waveguide structure. The waveguide structure can be made from a portion of the surface on which the embedded conductive particles are exposed. The waveguide structure can be molded as part of the antenna body or cut into the antenna body using a laser, which also exposes the conductive particles. If the waveguide is molded as part of the antenna body, the conductive particles can be exposed by an etching process or by using the laser. In this way, the described apparatuses and techniques can reduce weight, improve gain and phase control, improve high-temperature performance, and avoid at least some vapor-deposition plating operations.

Abstract: A method of detecting occupants within a vehicle includes receiving camera data, thermal data and radar data with respect to the vehicle. The received data is stored to at least a first buffer and a second buffer, wherein the first buffer has a length associated with a first duration of time and the second buffer has a length associated with a second duration of time greater than the first duration of time. The camera data, thermal data, and radar data stored in the respective first and second buffers is analyzed to detect and track camera-based objects, radar-based objects, and thermal-based objects, which are utilized to generate an output indicating whether an occupant was detected.

Abstract: A head-up display system having a diffusing image plane or diffuser. The light output of a relatively small image source is imaged on the diffuser by way of imaging optics. A mirror is used to image light from the diffuser onto a windshield and correct for distortion caused by the windshield. The diffuser is advantageously used when a large field-of-view is desired, or sun load characteristics need to be addressed. The diffuser may be flat or curved in order to optimize the system for different applications. The magnification of the mirror may be made relatively low, and the solar emergency density that is made incident on the image source is reduced, providing for a low cost, high performance, color head-up display system. A drive mechanism allows selective operator controlled repositioning of the image source and imaging optics with respect to diffuser to vary image size, position and/or intensity.
