  • Small diameter radiation sensor cable
    Patent number: 8953912
    Abstract: A simple method of making robust radiation sensor cables using a special fiber cap that holds a scintillating fiber therein directly abutting an end of a fiber optic cable, thus providing a clean and protected connection therebetween.
    Type: Grant
    Filed: August 27, 2014
    Date of Patent: February 10, 2015
    Assignee: RadiaDyne, LLC
    Inventors: Steven C. Lepke, Eric Hyman, John Isham, Randy Dahl

  • Small diameter radiation sensor cable
    Patent number: 8885986
    Abstract: A duplex plastic optical fiber may be used to create a dual detector system, which allows for the detection of two distinct areas of radiation in a single sensor cable device. A fiber cap holds a scintillating fiber and slides over an exposed portion of an optical fiber adjacent to an end of the optical fiber to create a concentric connection for a radiation sensor cable used in medical radiation therapy.

  • Optical object detection system incorporating fiber optic coupling
    Patent number: 5291261
    Abstract: A system (4) for use in an automobile (2) for the detection of objects comprising: a light source (6); a plurality of spaced transmitter ports (10, 12) for respectively transmitting light to a plurality of fields of illumination (18, 20); an optical fiber coupling the light source to the transmitter ports; a plurality of receiver ports (10, 12) embracing respectively a plurality of fields of reception (34, 36) each having an area of overlap (38, 40, 42, 44) with each of the plurality of fields of illumination so as to receive light transmitted from one of the transmitter ports and reflected by an object present in an area of overlap; a receiver (22) for receiving light and for producing a signal representative thereof; an optical fiber (24) coupling the receiver ports to the receiver; and processing means (52) for sequentially activating each of the transmitter ports with each of the receiver ports, and for processing the signal produced by the receiver in response to each activation to detect the presence of
