Patent CA-2081041-A1 (CA)
Inventor: BEECHER ROBERT L
IPC: H04N7/14
Filed: 1992-10-21
Abstract: A two-way video telephone station includes a television screen for displaying an image transmitted by a distant party to a telephone conversation, a video camera for electronically photographing a human subject and periodically transmitting his picture to the distant party, and position-indicating apparatus for keeping the subject within the camera's field of view.  The position-indicating apparatus includes a pair of light-emitting diodes (LEDs) - one on each side of the camera.  The LEDs are visible to the subject when he is out, or almost out, of the camera's field of view.  Because the LEDs can only be seen when the subject needs to take corrective action, they act as passive restraints that are completely unnoticed when the subject is properly positioned.  Red LEDs are used to indicate that movement should stop if the subject wishes to be centered in the picture transmitted to the distant party. In an alternate embodiment of the invention, a third LED is added which is green in color and is only visible to the subject when he is within the camera's field of view.  Advantageously, the subject sees yellow light when he is at the edge of the camera's field of view.

Patent CA-2101635-A1 (CA)
Inventor: JONES JAMES B
IPC: G01S13/78
Filed: 1992-01-21
Abstract: A digital video quantizer for use in TCAS and ATCRBS/SIF systems. A digital delay receives a digitized video signal and produces a plurality of delayed digital signals which are used throughout the quantizer. A threshold generator then produces a predetermined threshold and a dynamic threshold, and a quantized video generator compares one of the delayed digitized signals to a threshold to produce a quantized video signal. A slope quantizer detects a slope of the digitized signal which exceeds either a positive or negative threshold. In addition, a rise time detector detects an excessive rise time in the digitized video signal, and a chip amplitude comparator provides a signal which is used in detecting Mode S  data bit values. The digital video quantizer's use of digital references rather than analog references, eliminates the inaccuracies caused by a reference voltage varying over time or temperature. The digital references also facilitate modification of the reference values at a later time.

Title: Frequency-dividing transponder including amorphous magnetic alloy and tripole strip of magnetic material
Inventor: LIAN MING R
IPC: G01V3/12
Filed: 1994-05-18
Abstract: ABSTRACT OF THE DISCLOSURE A frequency-dividing transponder for detecting electromagnetic radiation of a first predetermined frequency and responding to said detection by transmitting electromagnetic radiation of a second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency, includes an active strip of amorphous magnetic material having a transverse uniaxial anisotropy defining a magnetomechanical resonant frequency in accordance with the dimensions of the strip at the second predetermined frequency when magnetically biased to be within a predetermined magnetic field intensity range so as to respond to excitation by electromagnetic radiation of the first predetermined frequency by transmitting electromagnetic radiation of the second predetermined frequency; and a tripole strip of magnetic material of such coercivity and so disposed in relation to the active strip of magnetic material as to create a magnetomechanical resonance in the active strip at the first predetermined frequency when the active strip is magnetically biased to be within the predetermined magnetic field intensity range. The transponder is used as a component of a tag that is attached to an article to be detected within a surveillance zone of a presence detection system, such as an electronic article surveillance (EAS) system utilized for theft deterrence. The presence detection system further includes a transmitter for transmitting electromagnetic radiation of a first predetermined frequency into a surveillance zone and a detection system for detecting electromagnetic radiation of the second predetermined frequency within the surveillance zone. The transponder may also include a bipolar bias strip of such coercivity and so disposed in relation to the active strip as to cause the active strip to be within the predetermined magnetic field intensity range at which the active strip has magnetomechanical resonance at the first and second predetermined frequencies. Alternatively, a magnetic field source, such as an electromagnetic bar magnet of high flux density core material that transmits electromagnetic radiation at a frequency in a range of from 1 to 100 Hertz, provides a magnetic field within the predetermined magnetic field intensity range within the surveillance zone so that when a tag including a transponder not having a bias strip is within the surveillance zone, the active strip of the transponder is within the predetermined magnetic field intensity range.
