Abstract: A method for localizing an RFID tag in a monitored zone comprises: emitting a reference signal from a reference RFID tag at a predefined reference position within the monitored zone, the reference signal including reference information; at a plurality of receivers, receiving the reference signal as a plurality of received reference signals; calculating a position of the reference RFID tag as a function of the received reference signals; comparing the calculated position of the reference RFID tag with the predetermined reference position for obtaining a test result; emitting an operation signal from the RFID tag, the operation signal including operation information associated with the RFID tag; at the plurality of receivers, receiving the operation signal as a plurality of received operation signals, comparing the received operation information with predetermined validation information associated with the RFID tag for obtaining a validation result; as a function of the test result and/or validation result, cal

Abstract: Various embodiments of a laser scanner apparatus and a method of operating a laser scanner apparatus, as disclosed herein, include the use of a variably blocked aperture or a controlled defocusing in relation to receiving backscattered light. One or more embodiments combine both variable blocking and defocusing and may use a lens design that complements the blocking and defocusing. Among the various advantages offered by one or more embodiments disclosed herein is a laser scanner apparatus that exhibits a flatter response curve to backscattered light over a defined range of distances. That is, among other advantages of the configurations and operating methods disclosed herein, a laser scanner apparatus experiences less variation in the optical power delivered to its photodetector arrangement, in relation to detecting an object at different distances within a defined range.

Abstract: A monitoring device for monitoring a boundary section of a safety zone for detecting an object at least partially entering or leaving the safety zone through the boundary section is provided. The monitoring device comprises: a light curtain device for detecting an object touching the boundary section; at least one radar device for detecting a movement direction of the object relative to the boundary section and/or a material property of the object; and an evaluation device for emitting an evaluation result based on a radar device signal from the radar device and optionally based on a light curtain device signal from the light curtain device.

Abstract: A method for operating a light curtain arrangement for monitoring a safety area is provided. The light curtain arrangement includes a plurality of first light emitter elements placed at an emitter side of the safety area, and a plurality of second light receiver elements placed at a receiver side of the safety area. The method includes the steps of: assigning a plurality of dedicated light emitter elements to a respective one light receiver element, wherein the assigned light emitter elements form an array; and activating the dedicated light emitter elements of a respective array to contemporaneously emit light, and at the same time, receiving the emitted light from the activated light emitter elements by the respective light receiver element.
