  • Method and apparatus for secure traffic light interruption
    Patent number: 7248183
    Abstract: This invention relates to a method and apparatus for secure traffic light interruption. A purpose of this invention is to allow for the use of a secure system to allow the interruption of the traffic light signals by emergency (and other authorized) vehicles. An objective of this invention is to allow for the use of a more secure system than the currently installed strobe only traffic light interruption (changing) systems. This invention integrates additional wireless technologies to assure that only authorized users trigger the traffic light changes that typically make it safer for emergency vehicles when they approach a traffic light.

  • Frequency-dependent phase pre-distortion for reducing spurious emissions in communication networks
    Patent number: 7248642
    Abstract: A frequency-dependent phase pre-distortion technique is applied to an input signal in order to reduce spurious emissions resulting from subsequent amplification of the signal. In preferred embodiments, the frequency-dependent phase pre-distortion of the present invention is implemented in combination with the (frequency-independent) magnitude and phase pre-distortion technique described in U.S. patent application Ser. No. 09/395,490 (“the '490 application”), where one or more frequency-dependent phase pre-distortion signals are either advanced or delayed relative to the main pre-distorted signal generated in accordance with the '490 application. Each frequency-dependent phase pre-distortion signal is preferably based on a 180° phase difference between a pair of (critical) frequencies located outside (e.g., one on each side) of the signal channel.

  • Wall plate adapter for coupling home network control signals to AC power wiring
    Patent number: 7247793
    Abstract: A wall plate adapter for coupling home network control signals to AC power wiring, where the wall plate adapter includes built-in signaling circuitry. The wall plate adapter includes a plate with a receptacle face with slots that are aligned with slots of an underlying AC receptacle. When prongs of a plug are inserted into the slots of the wall plate adapter, they touch contacts that are located in the slots of the receptacle face. The contacts are, in turn, coupled to the signaling circuitry, which may be located in an enlarged region of the wall plate. The signaling circuitry is only coupled to the AC power when a plug is inserted. The plug may be coupled to a transformer and a network device.
