Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

G02B 6/26

US Classification:

385 15, 385 12

Abstract:

A safety light curtain comprises a light emitter and a first micro-machined electromechanical system (MEMS), wherein the first MEMS receives light emitted by the emitter and sequentially reflects the received light to a first plurality of light wave guides. A detector receives an optical signal relating to light from at least one of the first plurality of light wave guides, the optical signal received by the detector employed to control operation of a machine associated with the safety light curtain.

International Classification:

H01H 27/00

US Classification:

200 4304, 200 4307, 200334

Abstract:

A safety switch that includes a body, a number of contacts, a movable plunger, a signal emitter, and a signal detector. The signal emitter and signal detector are positioned proximate the plunger and configured to assess the operability of the safety switch. The plunger is configured to selectively allow or prevent passage of a signal emitted from the signal emitter toward the signal detector depending on a position of the plunger. Control circuitry in connection with the signal detector is arranged to generate a control signal based on the detection of the emitted signal and configured to control operation of the safety switch independent of the relative position of the number of contacts.

International Classification:

H01J 40/14

US Classification:

2502221, 250221, 340556

Abstract:

Systems and methods are disclosed that facilitate increasing a coverage area for an emitter-receiver pair in a light curtain by generating multiple light beams from a single emitter and aggregating the light beams at a corresponding receiver. A plurality of light beams can be generated by reflection off of a MEMS mirror associated with the emitter, which can then be reflected from receiver-side mirrors along generally parallel paths, to corresponding emitter-side mirrors, which in turn reflect the light beams back to a MEMS mirror associated with the receiver. The receiver-side MEMS mirror can aggregate the reflected light beams for detection thereof by the receiver. According to a related aspect, transmissive LCD arrays can be employed at both the emitter and receiver to generate and recombine a plurality of light beams, respectively.

G02F 1/1345

US Classification:

356399, 356121, 356138, 356432, 349139

Abstract:

Systems and methods are disclosed that facilitate tolerating and/or correcting light beam misalignment in a light-emitting device, such as a light curtain. Attributes of the light beam can be assessed and compared to predetermined threshold values to evaluate whether the light beam is misaligned, and corrective feedback can be generated to adjust the position of one or more transmissive apertures generated on an LCD, through which light is permitted to pass, in order to re-align the light beam.
