  • Safety switch system with photooptical and capacitance detection
    Patent number: 5410148
    Abstract: A switch system for an industrial machine is described which combines both optical and capacitance switches in a switch assembly. A photo-optical switch is positioned in each assembly to provide an output signal upon the introduction of a human hand into an opening formed therein, and a capacitance sensitive touch plate switch is positioned within the opening to provide an output signal upon contact by a human hand. Circuitry responds to the substantially simultaneous activation of both the optical and capacitance switches within the switch assembly and produces an output signal. Typically two of such switch assemblies are used to control power to an industrial machine.

  • Control circuit for model railroads
    Patent number: 5321344
    Abstract: A control circuit for a model railroad utilizes a digital counter to control the modes of motor operation. To select a mode of operation a switch is used to repeatedly ground the base of a transistor circuit, causing pulses to be sent to a counter. By using the switch to hold the base of the transistor to ground, the counter sequencing is locked and prevented from further sequencing until the track power is turned off for a defined minimum amount of time. Release of this switched ground places the circuit under track control where short power interrupts cause the counter to sequence to the next count and therefore to sequence the modes of motor operation.

  • Obstruction position detecting system with comparison and memory means
    Patent number: 5243183
    Abstract: The present invention employs a plurality of spaced light beam sources and corresponding photodetectors to form a light screen. A programmed microprocessor and memory circuitry senses the photodetector output and stores information on the position of an allowed obstruction. During operation of the equipment, the microprocessor repeatedly senses the photodetector output to determine which channels are blocked. When dangerous changes occur in the size, position or presence of an obstruction, the system alerts the operator or stops the equipment.

  • Filter life indicator for water purification system using magnetically actuated switch
    Patent number: 5236578
    Abstract: A filter life indicator is described herein utilizing a constant flow channel and a flow actuated switch incorporating a reciprocating magnetic member to start a timer. Circuitry monitors this timer and actuates a visual or audible indicator when the filter needs to be replaced. The timer consists of a pulse generator, a scaling circuit, a counter, and a comparator. During flow pulses are counted and compared to a preset limit. And to accommodate filters having differing life expectancy, modules corresponding to each filter are installed to change the scaling circuit.
