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: A method and apparatus for recording video data in a surveillance system comprising receiving video data from a surveillance camera, recording the received video data at a first rate, and recording the received video data at a second rate with the second rate being slower than the first rate.

Abstract: The present invention provides a method and apparatus, including a processor and software incorporating a table that contains sets of pre-determined correction values that are used to supply different amounts of power to an electric stepper motor when the motor is operating at different speeds. Use of the correction values in the table allows power to be supplied to the motor in differing amounts that are approximately the same as the power actually required by the motor at different motor speeds or ranges of speeds.

Abstract: The present invention is a method and apparatus that allows the torque of an electric motor to be increased allowing the motor to be operated at higher speeds and at higher torque without raising the supply voltage, thus allowing for a wider dynamic range of speed and torque to be realized. This is accomplished by connecting one or more capacitors in series with each motor winding, and selectively activating the capacitors at higher speeds where the frequency of the motor resonates with that of the capacitor(s). Switching a capacitor into the circuit with the motor in a particular frequency range allows higher currents to flow through the motor windings resulting in higher torque.

Abstract: The present invention is a circuit for use with a video camera that extends the dynamic range of the camera allowing a limited-range output device to see brighter and darker portions of an image at the same time, and also increasing the low-light sensitivity of the camera, which is of great value in a security application. The circuit of the present invention matches the output dynamic range of a CCD imager to an ADC and subsequent DSP/ASIC by using a logarithmic function to fit a wider input dynamic range onto a narrower output dynamic range.

Abstract: A device and method is provided for reducing flicker on a video display. The device may be incorporated into a video surveillance system having a number of cameras, monitors, a keyboard controller, a switch, and a flicker reduction circuit. The flicker reduction circuit processes dual interlaced fields of video data with a field FIFO memory area, a line FIFO memory area, and a logic unit. The field memory area acts as a delay to store the field previous to the field being processed, while the line memory area stores the least recent line input from the field memory area. The logic unit computes the flicker-reduced scan line intensity for a given scan line by averaging the given scan line intensity with the resultant scan line intensity average of the two immediately adjacent scan lines in the complementary field.
