A sensing edge for providing a signal to a controller indicating that a forward edge of a door is obstructed during operation is provided. The sensing edge includes an elongate sheath and a first end plug assembly having a first end plug and a first end flap. The first end plug includes an engaging structure which is positioned within a first cavity of the sheath in an assembled configuration. The first end flap includes a body having a top edge and an opposing bottom edge. The top edge includes a first overhang and the bottom edge includes a second overhang. A third overhang is provided between the first and second overhangs. The first overhang is at least in partial facing engagement with an upper surface of the first end plug and the third overhang is at least in partial facing engagement with a lower surface of the first end plug.

Sensing edge

A system for detecting presence of an external obstacle combining contact and non-contact sensing in a common safety edge of a motorized closure includes a sensing edge with an elongate sheath forming a cavity in which two electrically conductive elements are physically and electrically separated. A control circuit includes an oscillator electrically connected to the conductive elements and that drives each at a drive frequency to establish an electric field. A controller is electrically connected to the first and second conductive elements and determines whether (i) the first and second conductive elements are in electrical contact with one another or (ii) a change to the drive frequency exceeds a threshold value. In response to a finding of either condition (i) or (ii), the controller outputs a signal to initiate or disrupt motion of the motorized closure. Two inductors connected to the conductive elements isolate the oscillator from the controller.

Combination contact and non-contact sensing edge

A system and method which allows automatic recognition of any of three common monitored motorized door or gate safety edges or other entrapment protection devices. The invention allows retrofitting existing motorized door operators without enough monitored input ports to allow for more monitored entrapment devices required on laterally moving motorized gates. The system interfaces with obstruction monitoring devices in normally closed, pulsed, or resistive termination operating environments found in entrapment protection systems. Firmware logically analyzes the state of each edge or entrapment protection device to select and direct an appropriate output signal for a motorized gate operator. An operational example is disclosed which provides for up to six different device inputs and two separate outputs for the motorized door operator, which can be configured through dual inline package switches allowing field configuration.

Multi-input module for motorized gate and door operators

A target is provided having a retroreflector. A body is provided having a spherical exterior portion, the body containing a cavity. The cavity is sized to hold the retroreflector, the cavity open to the exterior of the body and having at least one surface opposite the opening, the retroreflector at least partially disposed in the cavity, wherein the retroreflector and at least one surface define a space therebetween. A transmitter is configured to emit an electromagnetic signal. A first actuator is configured to initiate emission of the electromagnetic signal, wherein the transmitter and the first actuator are affixed to the body.

Measurement system having air temperature compensation between a  target and a laser tracker

Target apparatus for three-dimensional measurement system

A target includes a cube corner retroreflector including three planar reflectors, each planar reflector capable of reflecting light, each planar reflector perpendicular to the other two planar reflectors, each planar reflector intersecting the other two planar reflectors in a common vertex, and each planar reflector having two intersection junctions, each intersection junction shared with an adjacent planar reflector for a total of three intersection junctions within the cube corner retroreflector. The target further includes a non-reflecting portion of each intersection junction, wherein, for at least one intersection junction, the non-reflecting portion is wider in a first region than in a second region.

Cube corner retroreflector for measuring six degrees of freedom

A method is provided of obtaining the characteristics of a target by a device. The method includes providing the target having a target frame of reference, a retroreflector and a body. Providing a contact element rigidly fixed with respect to the body. A device is provided having a frame of reference and a light source, the device configured to measure a distance and two angles from the device to the retroreflector reference point. An identifier element located on the body. A workpiece surface is provided. The contact element contacts the workpiece surface. The retroreflector is illuminated with light from the light source and returns a reflected light. A distance and two angles are measured based at least in part on the reflected light. The first information is read with a first reader attached to the device. A three-dimensional coordinate of a point on the workpiece surface is calculated.

Target method using indentifier element to obtain sphere radius

A target includes a contact element having a region of spherical curvature, a retroreflector rigidly connected to the contact element, a transmitter configured to emit an electromagnetic signal, a temperature sensor disposed on the target, configured to measure an air temperature, and configured to send the measured air temperature to the transmitter.
