The processor may be capable of processing the reflected signal to provide an output indicative of a speed and position of the elevator component.

  • Patent number: 8469155
    Abstract: A gate below an elevator car which prevents access to an elevator hoistway. The gate slidably mounts behind a toe guard and retracts upwardly if the bottom of the gate encounters a person, object or the floor of the elevator pit during downward travel of the elevator. The gate latches when fully retracted so that it may be out of the way during maintenance. A microswitch is wired into the emergency stop circuit that engages when the gate is latched. A trip wire defining the bottom edge of the gate is also wired into the emergency stop circuit, so that the elevator will stop its downward travel if it encounters an obstruction. Rubber bumpers on the bottom edge of the gate cushion impact to people or objects who happen to be below the elevator car and are struck by the gate during downward elevator movement.

  • Publication number: 20130015022
    Abstract: Information equipment arranged in an elevator shaft generates shaft information with respect to movement of an elevator cage in the elevator shaft, wherein a code arranged at a hanging cable and readable by means of a reader provides information for generation of the shaft information. The hanging cable conducts energy and signals to the elevator cage and signals from the elevator cage to an elevator control and at the same time serves as a carrier for the code for generation of the information.

  • Patent number: 8307953
    Abstract: Elevator cabin position detection system comprising an activation device mounted on an elevator car, a sensor stripe mounted on a sidewall of an elevator shaft and control electronics. The activation device, preferably a light emitting device, activates a portion of the sensor stripe which comprises a feed line, a resistor line and sensors positioned between these. The sensors, preferably optical sensors, when activated by the activation device, conduct electricity to create electrical connection between the feed line and resistor line and thus modify the resulting resistance between an end (A) of the resistor line and an end (B) of the feed line. The control electronics determines the exact position of the elevator cabin based on the resulting resistance between the end (A) of the resistor line and the end (B) of the feed line.
