Abstract: A system for silently communicating a horn-signal between vehicles is provided. The system includes a sending-vehicle equipped with a horn-button operable by a horn-operator, a transmitter configured to transmit, using electromagnetic-energy, a horn-signal in response to the horn-operator operating the horn-button, and a first location-device configured to determine a send-location of the sending-vehicle. The transmitter is configured to incorporate the send-location into the horn-signal. The system may also include a receiving-vehicle different from the sending-vehicle. The receiving-vehicle is equipped with a receiver configured to detect the horn-signal, and a second location-device configured to determine, based on the horn-signal, a relative-location of the sending-vehicle relative to the receiving-vehicle.

Abstract: A touch-sensitive display system includes a display, a contact detection means, and a hover detection means. The display is configured to display an image toward a surface of the display. The contact detection means is configured to determine a contact location on the surface indicative of where a finger contacts the surface. The user input is determined based on content of the image at the contact location. The hover detection means is configured to determine a hover location of the finger relative to the surface when the finger is within a hover distance of the surface. The system is further configured to magnify a selected portion of the image that corresponds to the hover location.
