Abstract: A density-optimized short-range wireless communications antenna system has a first radiating element, a second radiating element, and a radio frequency transmitter that generates a radio frequency signal. A power divider has an input port connected to the radio frequency transmitter, a first output port, and a second output port connected to the second radiating element, and a signal power of the radio frequency signal is split between the first output port the second output port. A phase shifter is connected to the first output port of the power divider and to the first radiating element, with a phase of the first split radio frequency signal being shifted by a prescribed degree relative to the second split radio frequency signal.

Abstract: An apparatus for combining any video and user-preferred data from the internet, a data collection processor, an on screen display generator and video mixer. The user-preferred data can be customized by the user on the apparatus or using a computer. The apparatus may be controlled by a remote control or hand or other gesture control may also used to control the apparatus. The apparatus also provides video conferencing mode. The apparatus provides speech to sign language conversion.
