Abstract: A vehicle includes a passenger compartment, a touch-screen for receiving an input signal from an occupant when the occupant touches the touch-screen, an output device, and a controller. The controller changes a characteristic of an electromagnetic wave in the form of visible light and/or an audible sound, which is transmitted into the passenger compartment via the output device in response to the input signal. The output device includes light sources, such as light-emitting diodes (LED) or electro-luminescent (EL) ribbon and a speaker. The controller presents a predetermined set of lighting and/or sound options on the touch-screen which the occupant can touch to generate the input signal, thus selectively illuminating the light sources or playing a particular sound file. The controller can also play a digital sound file whenever a corresponding vehicle condition is detected.

Abstract: A flat panel antenna array for generating multiple beams across a wide frequency band. Radiating elements and feeds are supported on radiator boards disposed in parallel planes, all perpendicular to a network board that supports a time delay structure, such as a Rotman lens, to phase the signal fed to respective radiating elements in order to form beams pointing in specified directions. Ground sheets, parallel to the network board and back structure of the antenna, interlock with a narrowed region of the radiator boards and with cross braces, providing mechanical support and overlap to reducing cross-polarized radiation otherwise coupled by slots in the ground sheets.

Abstract: A modular array antenna. The antenna has a plurality of radiating elements fed by a hybrid waveguide/stripline network that includes a waveguide power splitter for coupling power into the stripline network. Components of the array antenna may be substituted for selecting polarization and beamwidth.
