Patent number: 9768212Abstract: The subject matter disclosed herein describes an optical sensor used in a safety system. The sensor includes two pixel matrices on a single substrate. Each of the pixel matrices are arranged in a row and column format, and pixels from one matrix are interspersed with pixels from the other matrix such that alternating pixels in each row and column belong to separate matrices. Two sets of selection logic allow each matrix to be enabled separately. Additional monitoring logic is included to detect shorted pixels and/or shorted selection lines. In addition, the frames generated by each pixel array may be compared to detect variation in performance between arrays.Type: GrantFiled: October 27, 2014Date of Patent: September 19, 2017Assignee: Rockwell Automation Switzerland GmbHInventors: Anatoly G. Grinberg, Wayne R. Foster, Martin Hardegger, Derek W. Jones, Simon Eggenberger, Carl Meinherz

Patent number: 9083946Abstract: A system to test operation of an optical sensor is disclosed. The optical sensor includes one or more photosensitive devices configured to convert light to electrical signals. A test light source is included within the housing of the optical sensor. The test light source is periodically pulsed on to emit radiation at a sufficient intensity to saturate each of the photosensitive devices. Each of the photosensitive devices generates a signal corresponding to the intensity of light detected at that device. A logic circuit uses the signals corresponding to the intensity of light to identify whether each of the photosensitive devices is performing at an acceptable level.Type: GrantFiled: February 21, 2012Date of Patent: July 14, 2015Assignee: Rockwell Automation Technologies, Inc.Inventors: Anatoly G.

Patent number: 8872113Abstract: A system to test operation of an optical sensor is disclosed. The optical sensor includes one or more photosensitive devices configured to convert light to electrical signals. A test light source and a reference target are included within the housing of the optical sensor. The test light source is mounted proximate to the photosensitive devices and the reference target is positioned opposite from the test light source. The test light source is periodically pulsed on to emit light at a known wavelength. The light is reflected from the reference target back to at least a portion of the photosensitive devices. A logic circuit uses the reflected light which is received at the portion of the photosensitive devices to determine the distance between the light source and the reference target. This calculated distance is compared against the known distance to verify correct operation of the optical sensor.Type: GrantFiled: February 21, 2012Date of Patent: October 28, 2014Assignee: Rockwell Automation Technologies, Inc.Inventors: Anatoly G.
