    摘要： Methods and apparatus are provided for measuring multiple operating parameters of a rotating shaft with a sensor. One embodiment of the apparatus comprises a sensor in close proximity to a matched pair of thumbnail depressions on the surface of a rotating shaft body. The thumbnail depressions enable the sensor to detect axial displacement and rotational speed of the shaft in addition to detecting radial displacement of the shaft body. Signal processing circuitry analyzes the sensor output data and computes separate values for the axial displacement, speed and radial displacement parameters. Additional filtering and signal processing techniques can be used to ascertain peak axial displacement, to reduce noise, and to compute other parameters, such as acceleration and power spectral density.

    摘要： An optical power converting apparatus is provided that may be used with remote sensors. A plurality of remote sensors may be coupled to a backbone optical fiber with each sensor having an optical power converter that receives an optical signal from a head end of that fiber. The optical power converters may store electrical energy derived from that optical signal and use that energy to power the remote sensors. The head end's optical signal may also include a clock signal, and each remote sensor may be set to sense a measurable parameter after a given number of clock cycles have been counted. In a further example, each of the optical sensors may be synchronized before counting these clock signals via a synchronization signal from the optical power converter. The remote sensors may individually and separately uplink their sensed data to the head end on the optical fiber. The apparatus may be implemented in a vehicle health management system, for example.

    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.
