Patent number: 6662007Abstract: A system for communicating information from a television viewer to a central site includes a remote control unit for sending command signals from the viewer to a television or video cassette recorder (VCR). Circuitry integral with the television or VCR accepts the command signals from the remote control unit and interprets the signals to form a viewer command, such as a purchase command, to be communicated to the central site. The circuitry automatically sends dual-tone multifrequency (DTMF) tone signals representing the command over a radio frequency (RF) link to a cordless telephone base unit, which is connected to the central site by a public switched telephone network. The cordless telephone base unit initiates a telephone call to the central site and communicates the DTMF tone signals received from the DTMF circuitry in the television or VCR to the central site.Type: GrantFiled: February 10, 1999Date of Patent: December 9, 2003Assignee: E-Guide, Inc.Inventor: Henry C.

Patent number: 6655214Abstract: An externally-powerable sensor is described for detecting ultrasonic energy and for providing an accurate indication of the level of such energy to an external monitoring device over a wide dynamic range. A first electrical signal proportional to the detected ultrasonic energy is chopped by the output of a free-running multivibrator to generate a signal having a frequency differing from the frequency of the first signal by an amount within the audio frequency range. Such difference signal is selectively amplified to concentrate the spectral energy of the difference component in a lower portion of the audio range. A low pass filter extracts, from the so-concentrated difference signal, a modified audio signal whose frequency content is at the lower end, illustratively 0-6 KHz, of the spectrum of the concentrated difference signal. The output of the low pass filter is processed to generate a DC output current that is proportional to the detected ultrasonic energy level.Type: GrantFiled: November 12, 2001Date of Patent: December 2, 2003Assignee: U-E Systems, Inc.Inventors: Mark A. Goodman, William Bishop
