Abstract: This is a security and identification system designed to obtain improved images for use by real-time facial recognition and identification systems for screening individuals passing through secure entry or checkpoints such as airport passenger terminals, government offices, and other secure locations. The system detects the presence of a subject at the checkpoint, interactively instructs the subject to stop and move into position for proper identification and recognition, analyzes the facial features of the subject as (s)he passes through the checkpoint, and compares the features of the subject with those in a database. The system then generates different signals depending upon whether or not the subject is recognized. In one aspect of the invention, different methods and apparatus are provided for compensating for low ambient light so as to improve the quality of the facial image of the subject that is obtained.

Abstract: An apparatus for and method of storing video data comprising receiving an MPEG video stream comprising I-frames and P-frames, separating the I-frames from the P-frames, storing the I-frames and the P-frames separately, and providing information so that the I-frames and the P-frames can be combined to produce a full-motion video.

Abstract: A synchronization signal generating apparatus and method in which an input circuit is inductively coupled to an alternating current signal line. The input circuit generates a rectified signal. A switch has a switch input and a switch output in which the switch input is electrically connected to the input circuit and is enabled when the voltage of the rectified signal is greater than a predetermined voltage and is disabled when the rectified signal voltage is less than the predetermined voltage. A pulse generating circuit has a pulse generating circuit input and a pulse generating circuit output. The pulse generating circuit input is electrically connected to the switch output. The pulse generating circuit generates a pulse each time the switch is enabled. The synchronization signal generating apparatus is used in a synchronized television display system to signal a video switch to switch the video signal generated by a camera to a monitor based on the occurrence of the synchronization signal.

Abstract: A system and method for setting the activation state of electronic article surveillance markers, tags, and labels being transported on a conveyor system is provided. The system includes a pair of electromagnetic transmitting coils mountable on opposite sides of a conventional conveyor section, an electronic controller, and can include a remote external controller for manual operation. The electromagnetic transmitting coils are mounted within sensor housings that include one or more sensors to automatically sense an article traveling on the conveyor system and trigger the transmission of preselected activation or deactivation electromagnetic pulses when the article is in the proper location. The system can include an inhibiting sensor input to prevent the automatic transmission of an activation/deactivation pulse for specific preselected articles. The system includes a logic scheme to preselect and shape the activation or deactivation electromagnetic pulse.
