Abstract: A control system for a conveyor system having one or more upstream and downstream conveyor zones and whose operation effectuates transportation of a series of loads via operation of motors and drive arrangements associated with the respective conveyor zones. The control system includes a Local Area Network (LAN) connection between each component of the control arrangement associated with each zone control such that status and operational information associated with the configuration or operation of each conveyor zone, including the zone motor, can be communicated to other conveyor zones so that operation of each conveyor zone can be manipulated in a controlled manner in response to changes to operation of other conveyor zones.

Abstract: A drive unit for a roller conveyor assembly having a motor and an integrated motor controller. The controller is mounted on a circuit board and connected to the rear of the motor housing. A cover for the controller substantially encloses the controller. An opening in the cover allows access to a terminal block from the controller. The terminal block receives wiring to external devices and to other zone controllers. Wiring between the circuit board for the controller and the motor is performed as a step in the assembly of the integrated motor and controller. The motor and controller are configured to be mounted below the rollers and between the side frames of a conveyor assembly. An output shaft from the motor is coupled to the rollers to power the conveyor assembly.

Abstract: A protection system has a power supply connected to lamps by a low value resistor. The resistor is part of a voltage divider system which provides input signals to a number of comparators. These comparators provide appropriate signals to a microprocessor to indicate normal operation. When a malfunction is detected, the voltage drop across the low value resistor changes and alters the output of the comparators. The microprocessor thereafter produces an appropriate warning signal. In a vehicle turn signal circuit, the present invention is incorporated to detect a burned out bulb. A warning is provided to the vehicle operator when a bulb is out. Further, pursuant to federal safety regulations, the remaining functioning bulbs, when activated, flash at a substantially slower rate.

Abstract: A turn signal control circuit has a power source, left and right turn signal inputs, a speed detection input and circuitry for conditioning the power source voltage and current as well as the input signals for proper operation. When a turn signal switch provides an input signal to a logic controller, the circuit begins flashing the respective turn signal. Upon release of the switch, a microprocessor reviews the vehicle speed by way of a speedometer input line and references a lookup table to determine the proper distance at which to turn off the signal. Generally, the faster the vehicle is travelling, the longer the turn signals are left on. Various manual cancellation options are also available to the motorcycle operator. A four-way flasher sysem is operated by simultaneously pushing the two turn signal switches, remaining on until both switches are again simultaneously pressed.
