    • Rocker buttons for devices such as automotive audio systems are mounted in escutcheons of the audio systems by using rocker frame members. Light dams, unitary with the rocker frame members shield LEDs used to illuminate indicia in the rocker buttons so that the light is not transmitted through gaps between the rocker buttons and the edges of openings through the escutcheons which receive the rocker buttons. Trunions extend laterally from the rocker buttons and are received within bearings formed by grooves in the escutcheons. In accordance with one embodiment of the invention, the rocker frames retain trunions in the bearings and in accordance with another embodiment of the invention peripheral display lenses overlie the trunions to hold the trunions in the bearings.

    • A modular test chassis for use in testing wireless devices includes a backplane and a channel emulation module coupled to the backplane. The channel emulation module comprises circuitry for emulating the effects of a dynamic physical environment (including air, interfering signals, interfering structures, movement, etc.) on signals in the transmission channel shared by the first and second device. Different channel emulation modules may be included in the test system depending upon the protocol, network topology or capability under test. A test module may be provided to generate traffic at multiple interfaces of SISO or MIMO DUTs to enable thorough testing of device and system behavior in the presence of emulated network traffic and fault conditions. A latency measurement system and method applies timestamps frames as they are transmit and received at the test module for improved latency measurement accuracy.
