Abstract: ABSTRACT OF THE DISCLOSURE         A time limited coherent frequency doppler radar system monitors a precisely bounded merchandise detection zone for motion of a transducer therein.  False alarms are reduced without limiting sensitivity by limiting the maximum radar signal propagation times to control the outer boun-daries of the detection region and by requiring a selected minimum motion within the detection zone.  An even more precisely bounded merchandise surveillance zone can be realized by using two spaced-apart radar systems having overlapping detection zones.

Abstract: ABSTRACT OF THE DISCLOSURE A verifier for use in a personal identification system of the type in which a generator receives at least a personal account number (PAN) and a secret personal identification number (PIN) and based thereon produces digits Ai's which are present in a feedback shift register (FSR) A and digits Ci's present in a feedback shift register (FSR) C respectively.  The Ai's and Ci's are mapped into Di's which represent digits of an Offset Number which together with the PAN are recorded on the magnetic stripe of a card.  To use the card, the Offset Number and the PAN are read off  therefrom and an intended user enters a secret PIN.  In the verifier, the PIN is operated upon to produce Ci's and the PAN is operated upon to produce Ai's.  The latter together with the Di's of the received Offset Number are mapped by a processor to form C?'s.  These are compared with the Ci's by a comparator to determine whether the intended card user is the rightful user.

Abstract: Abstract An electronic control system for a steering assembly having an electric motor coupled to the steering assembly for providing power assist.  The electric power assist motor is drivably connected to a steering member for assisting movement thereof in response to applied input torque to the vehicle steering wheel.  The electronic control unit monitors an output signal from a torsion sensor which measures the amount of applied input torque.          The electronic control unit generates a pulse width modulated signal having a duty cycle proportional to the measured amount of applied input torque.  Solid state switches provide connection between the vehicle battery and the motor, the connection time being controlled by the duty cycle of the pulse width modulated signal.  A speed decoder determines which of a plurality of speed ranges the vehicle is moving.  A plurality of look-up tables are provided, each table includes a value of power assist for a given amount of applied input torque.  A look-up table is selected depending upon the decoded vehicle speed.  Soft start circuitry is provided to control the maximum amount of assist that is permitted upon initial application of power to the electronic control unit.  The amount of assist permitted increases from a minimum to a maximum within a predetermined amount of time.  Temperature foldback circuitry is also provided to limit the amount of current through the electric power assit motor dependent upon sensed temperature of the solid state switches.  The amount of current permitted through the motor is also limited to an absolute maximum.  A connection cable is provided to reduce radiated electromagnetic emissions and voltage transients.
