摘要： An ultrasonic imaging system and method for imaging human or animal tissue having a surface and including a probe including a platen for supporting the human or animal tissue for imaging the same, a transducer positioned closely adjacent the supporting means for providing an output ultrasonic beam directed on the surface so that the size of the beam at its focal point is as small as possible to maximize the resolution of the system and a mechanism for moving the transducer in two directions so as to provide a two dimensional scan of the surface by the ultrasonic beam. There is also provided a scan controller operatively connected to the probe for controlling the mechanism to provide the scan of the surface and a signal processor operatively connected to the probe for receiving signals produced in response to the scan of the surface and for processing the signals. In a form of mechanism wherein an oscillatory motor moves the transducer to direct the ultrasonic beam along an arcuate path, there is provided an encoder operatively associated with the motor for providing information on the amount of angular rotation provided by the motor. There is also provided an oscillatory flexible liquid impervious seal between the motor shaft and a liquid filled region containing the transducer in a manner causing minimal drag on the motor. The system and method can be employed in fingerprint scanning and processing, and in biometric identification and verification systems wherein the imaging system is utilized in combination with a record member containing a recorded biometric image and a processor for performing comparisons.

摘要： A system and method for controlling an appliance, such as an indoor ceiling fan, including a controller operatively connected to the appliance motor for controlling its speed and direction of rotation in response to command signals, a control switch adapted to be located remote from the appliance such as a on a wall to provide command signals in response to manual inputs, and a communication link such as the existing a.c. power line, for transmitting command signals from the control switch to the appliance controller. The control switch is characterized by a plurality of operator members such as a keypad each providing no more than one distinct primary function command when manually operated and a processor for converting function commands provided by the operator members into speed and direction command signals for use by the appliance controller. The appliance controller comprises a processor for converting command signals received by the controller into signals for controlling the supply of motor current. The command signals transmitted from the control switch to the appliance controller over the a.c. power lines are digital signals generated by a pulse code modulation method. The appliance can have a lamp associated therewith and means for controlling the brightness thereof in response to commands from the control switch. The system can include a plurality of appliances and associated controllers whereupon the control switch provides address information for selecting particular ones or groups of the appliance controllers.

摘要： A circuit providing a ramp signal having dual slopes of increasing and decreasing magnitude is controlled to provide one of its ramp portions with a slope which varies in accordance with a signal perturbing effect and the other of which is constant. The dual slope ramp duration is modified in proportion to the perturbing effect and is used to compensate therefor.
