One aspect of the present disclosure can include an electronic signal processing system and method used in a control system (e.g., for hour meter functionality, intelligent start/stop functionality, etc.). The system can include a rectifier component to receive a voltage input from an operation source during use. The voltage input can indicate that an engine is running. The rectifier component to convert the voltage input to a positive voltage input. The system can also include a constant current component to receive the positive voltage input from the rectifier circuit and to control a current based on the positive voltage input. The system can also include an optical component to provide an output based on the current and to communicate the output to a microcontroller during use of the operation source. For example, electronic signal processing methods and apparatuses are also described.

Universal signal processing system and method

A switch assembly and method for use with power equipment, the switch assembly comprises a housing assembly for having an actuator opening, the opening defining spaced first and second internal housing positions and a removably located actuator for selectively positioning within the opening of the housing assembly for altering the operation of power equipment. The switch assembly further includes a first switch corresponding to the first housing position to selectively provide power to one or more components of the power equipment and a second switch corresponding to the second housing position such that the second switch is spaced away from the first housing position, the second switch for detecting the presence and position of the actuator such to further alter the operation of power equipment.

Switch assembly and method of operating same

A system and method for charging a merchandise item is presented. A power supply system for charging the merchandise item includes: a power supply unit, a power cable with a cable control logic. The power supply unit includes a variable power supply and power supply control logic. The power supply can be attached at one end to a power socket of the merchandise item and at the other end to the power supply unit. The cable control logic reads a power requirement from a charge adaptor logic located near the end of the cable connected to the merchandise item and communicates it over the power cable to the power supply control logic. The power supply control logic controls the variable power supply based, at least in part, on the power requirement so that the variable power supply generates a supplied voltage onto the power cable to power the merchandise item.

System for charging displays

Apparatus, systems and methods for correcting data received from a power cable is presented. A method receives communication data from a near end of a cable that has near and far ends. The data is compared using hysteresis to a high threshold and/or a low threshold. The data is reset to produce corrected data by resetting the data to either a high value or a low value based on the comparing. For example, when the corrected data is high, the data is reset to a low value when the communication data crosses the low threshold and when the corrected data is low, the data is reset to a high value when the communication data crosses the high threshold. The corrected data can provide a power supply data needed so that it can more accurately provide a power through the cable to the far end of the cable.

Analog compensator circuit to compensate for cable loss

A setup and calibration unit for a barrier operator is operable to communicate with the operator's own controller. The calibration unit includes a control circuit connected to a visual display and to a set of switches controlled by switch actuators for placing the operator controller in a controller run mode or calibration mode, scrolling through selected actions displayed on the display in one direction or the other, a set/clear function and display backlighting for user interaction with the setup and calibration unit. The setup and calibration unit is particularly adapted for use with upward acting sectional and roll-up doors and other types of barriers movable between open and closed positions by motorized operators. The calibration unit may be operably connected to the operator controller via hard wiring, a radio frequency link or an infrared or visible light transmission link.

Calibration and setup unit for barrier operator control system

A battery operated controller for a door operator includes a keypad backlit by a light emitting diode operably connected to a microcontroller which also controls operation of the controller. The microcontroller periodically measures ambient light as sensed by the light emitting diode and when a voltage level related to a predetermined light intensity decreases below a predetermined level the light emitting diode is energized to provide backlighting for the controller keypad. The intensity of backlighting may be varied in accordance with the amount of ambient light illuminating the keypad and above a certain intensity of ambient light the light emitting diode is de-energized to conserve battery power.

Device including light emitting diode as light sensor and light source

An operator for a barrier, such as an upward acting door, includes a control unit having two optical limit switches providing output signals to a controller to effect shut-off of the operator motor when the door reaches open and closed limit positions. The limit switches preferably include LED emitter and phototransistor sensor elements and are preferably mounted on a circuit board in close proximity to a screw member which rotates in timed relation to the position of the door. Linearly movable nut members are mounted on the screw member and include or engage optical shield members which move into positions to provide respective output signals from the optical switches. The door closed optical limit switch may incorporate a pre-limit switch function to override a signal from a door bottom edge obstruction sensor.

A console or controller unit for a garage door operator includes a message recording and playback device. The console unit may be wall mounted or configured as a remote transmitter type unit and includes a molded light transmitting switch actuator part mounted on a housing part of the console unit between an outer wall and a circuit board and comprising integrally molded door operator, garage lighting and message record, playback and erase switch actuators. LED indicators provide light for illuminating the switch actuators and for indicating a message waiting and low battery power. The message recording and playback circuitry is electrically isolated from the door operator control circuitry and is battery powered. The message recording and playback device includes a programmable microcontroller for controlling a voice message recording and playback circuit.

Door operator console

A control unit for a moveable barrier, such as a garage door, includes a microcontroller connected to a motor speed detector, motor current sensor or a sensor for determining forces exerted on or by the barrier. A user interface includes user actuatable switches for setting a first maximum force value to be exerted on or by the barrier when moving in one direction and the microcontroller automatically sets the value of a second maximum force to be exerted on or by the barrier when moving in the opposite direction. The second force value may be based on the force value set by the user or the second force value may be a preset value. Both force limits may be automatically set as a function of a maximum force exerted on said barrier during movement thereof, during a force learning operation.

Barrier operator controller with user adjustable force setpoint

A console device for controlling a door operator for a motor operated door includes a housing; a transmitter unit, a door operator control circuit, a user accessible door operator switch operable to control a door, an LED driven menu operably connected to the control circuit, an alphanumeric keypad and user input push buttons. The LED driven menu provides visual programming feedback to the user. The LED driven menu may provide feedback such as a home state or ready indicator, a door selector, user code or PIN assignment designators and a programming error indicator.
