Abstract: A method of assembling a remote keyless entry transmitter (10) having a housing and at least one battery in the housing includes the steps of providing a first housing part (70) and a battery (80, 82) to be assembled with the first housing part; positioning the battery in a desired location on the first housing part; and applying a magnetic field to the battery to maintain the battery in the desired location in the housing part during further assembly of the remote keyless entry transmitter.

Abstract: A vehicular, infrared, multiplexing system controlling various vehicular or automotive electrical function loads, such as, for example, lights, window motors, seat motors, door locks, engine start and the like, wherein control and sensing signals are transmitted within the interior of the vehicle by randomly reflected, infrared radiation or similar optical energy carrying electronically intelligible information. The infrared system does not require or rely on direct, light-of-sight or controlled reflection or a continuous optical circuit, but instead relies on randomly reflected, scattered, diffused, infrared radiation reflected from various interior surfaces of the vehicle, including, for example, practically all interior surfaces, such as the windshield, side and rear windows, seats, headliner, instrument panel, rear window, door trim panels, etc.
