    摘要: System(s) and method(s) that facilitate utilizing biometric sensors (e.g., fingerprint, hand scan, voice recognition . . . ) in manufacturing systems in order to maintain accurate safety audit trails. A safety audit system, utilizing a biometric sensing device, facilitates determining if a user is allowed to access and change the configuration of the manufacturing system. Once a user is allowed to change the configuration (e.g., programmable electronics, tooling changes, software updates, etc.) the changes are automatically recorded in a safety audit database. Automatic storage of configuration changes mitigates manual recording of changes thereby enhancing the safety audit data often necessary to meet safety standards for manufacturing systems.

    摘要: 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.
