A wall control unit for a movable barrier operator sends baseband signals over a wire connection to a head unit of a movable barrier operator to command the movable barrier to perform barrier operator functions. The wall control unit has a wall control unit port for connection to the wire connection. A first switch sends a barrier command signal to the head unit commanding the head unit to open or close a movable barrier. A second switch commands the head unit to provide energization to a light source. An infrared detector causes a command signal to be sent to the head unit to control the illumination state of the light source.

A power factor controller for an AC induction motor which controls the input power to the motor commensurate with the loading on the motor so as to improve efficiency. The circuit provides a signal representative of the phase difference between the current through the motor and the voltage across it. The phase difference varies with motor loading and accordingly is utilized to control the input power to the motor. The improvement in efficiency is displayed in terms of the percent savings provided by the controller. The circuit provides an immediate response to initial energization of the motor to enable the motor to reach full speed in minimum time.

A shell-form transformer for charging an energy storage device contained in a battery powered impact device. The primary and secondary windings of the transformer are wound in a predetermined manner around the center leg of a core which has an air gap therein. The gap increases the reluctance of the center leg which decreases the flow of magnetic flux through the core which, in turn, enables the current applied to the transformer primary to be increased without causing the core to be saturated. As a result, the current applied to the transformer primary can be increased, thereby increasing the output voltage supplied from the transformer secondary which, in turn, enables rapid charging of the energy storage device.

A remote control system for a video computer game having a portable controller unit with transmitter circuits responsive to manipulation of a joy stick for generating RF signals indicative of such manipulations. A reset switch and a game select switch is also provided for generating signals which are also sent as RF signals. A central receiver receives the RF signals from the portable controller unit and converts the manipulation signals into signals applicable to control the video game. The reset signal and the game select signal are sent to an actuator unit which is physically mounted onto the master control center and includes mechanical actuator mechanisms to mechanically engage the reset and game selector buttons on the master control center. The central receiver also includes detection elements to prevent random signals from disturbing the game during such time periods when it is not receiving signals from the transmitter controllers.

318729

A power factor controller for AC induction motors having a control triac connected in series with the motor for controlling the voltage applied across the motor to reduce the power to the motor commensurate to motor loading. A sensing circuit produces square wave pulses representative of the phase difference between the current through the motor and line voltage across the motor. A reference circuit provides a reference signal representative of the full cycle of the pulse. A comparison circuit compares the output of the sensing circuit with the reference circuit and produces the phase lag signal for the control circuit. In a digital embodiment the sensing means and reference means each respectively control gated clocks whereby the count is representative of the duration of the pulse. In an analog version there is included an integration circuit which produces an output voltage level proportional to motor loading. A regenerative feedback circuit is coupled across the integration circuit and responds to turn on of the motor as well as application of sudden loads to the motor to provide full voltage to the motor.

A device for remotely controlling call forwarding for a given telephone line. The device includes a detection circuit for detecting an incoming call to the given telephone line. If it detects only one or two signals indicating a previous call forwarding initiate setting, it automatically terminates call forwarding and awaits input of a new call forwarding telephone number followed by a security code. If it detects more than four rings, it knows that the call forwarding was not enabled and it is ready to accept the new call forwarding number remotely input along with the security code. After receiving successfully the remotely inserted call forwarding number and security code, it proceeds to reprogram the system with the new call forwarding number. Should any unauthorized user be using the system, it will reprogram with the previously stored call forwarding number.

Solid state control circuitry for driving an electromagnetic armature of a battery operated electric stapler. The armature is activated by a trigger signal generated by a trigger switch which discharges an energy storage device through the armature. Energy is rapidly replenished in the energy storage device following its discharge; but if a subsequent trigger signal is not forthcoming, the control circuit reverts to a quiescent state, thereby reducing power consumption.
