摘要： In an entry detection system, detection of an object that is allowed to enter the region is appropriately disabled. An entry detection system for detecting an object entering a region includes: an entry detection sensor configured to detect whether or not a part of the object is present within an entry detection plane; a muting sensor section including a first unit and a second unit; and a control unit. The control unit disables the entry detection sensor in response to at least one of a first detection state and a second detection state being established, the first detection state is a state in which the first unit provided on a passing direction-first side of the entry detection plane detects the object, and the second detection state is a state in which the second unit provided on a passing direction-second side of the entry detection plane detects the object.

摘要： The invention relates to a workpiece processing machine (1), and to a method for operation of a workpiece processing machine (1). The workpiece processing machine (1) comprises an automatically adjustable stop finger (17), and has, for monitoring adjustment movements of the stop finger (17), a monitoring device (36, 37, 38) that comprises an illuminating device (36) and at least one optical detection device (37). In operation of the workpiece processing machine (1), during an automatically controlled adjustment movement of the stop finger (17), a light beam (38) is radiated into an area ahead of the stop finger (17) in the adjustment direction. Upon detection of a first light image (43) projected onto an object surface (42) by the first light beam (38), a safety measure is triggered.

摘要： Apparatus and associated methods relate to a light curtain protection system having a passive optical module arranged to receive, from an active optical module, a light signal such that a reflector reflects, through a polarization control module, the light signal to be received by a receiver in the active optical module. In an illustrative example, the polarization control module includes a half-wave plate aligned with the reflector to impart a first predetermined polarization to the reflected light signal such that the reflected light signal corresponds to a second predetermined polarization when received by the receiver. The polarization control module includes optical elements, such as, for example, a linear polarizer, to receive the reflected light such that the optical elements polarizes the received reflected light signal to correspond to a predetermined polarization. In some examples, the light curtain protection system may advantageously require operating power only for the active optical module.

摘要： A first embodiment of the disclosure provides a system for detection of intrusion into a working space of a material testing device wherein visual user detection system uses digital image processing and filtering in order to identify user entry into the specimen test space. The visual user detection system has built-in redundancy for safety compliance and further can be used for data entry with respect to test data setup and configuration. A second embodiment of the disclosure uses a digital camera mounted on the frame of the material testing device, oriented toward a striped pattern on the top of the front base cover. The striped pattern is recognized by a vision algorithm which creates virtual boundary lines within the pattern. A detected intrusion, such as by a user body part, will be detected and the material testing machine put into a safe state.
