Abstract: Thin, flexible antenna arrangements for use in communication devices, such as mobile communications devices, and methods of making and using the antenna arrangements are provided. The methods used to make the antenna arrangements are print-based and provide a simplified procedure, with a reduced number of process steps, the use of fewer materials and the production of less material waste than conventional methods based on etching and die cutting.

Abstract: A motor vehicle has a video system that analyzes images of the interior of the vehicle to detect certain characteristics for controlling functions of the vehicle, such as detecting the presence of a person on the seat to control deployment of air bags in the event of a crash. The system employs infrared light to illuminate the vehicle interior without affecting the driver's ability to see the highway. In order to distinguish different objects in the image which have similar colors, such as a person dressed in black sitting on a black seat, a selected object, such as the seat, are coated with a substance that alters the object's reflectivity to infrared light, while not changing the reflectivity to visible light. Thus analysis of the infrared image can distinguish between the objects without affecting the appearance of the vehicle interior to a human user.
