    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： The present invention relates to circuits configured for implementation in sensors, sensors employing such circuits, and methods of operating and manufacturing such sensors and/or circuits. In at least some embodiments, the circuit includes a capacitor having a first input terminal and a first output terminal, a first amplifier having second and third input terminals and a second output terminal, and a second amplifier having fourth and fifth input terminals and a third output terminal. The first output terminal of the capacitor is coupled at least indirectly to the second input terminal, the fourth input terminal, and the third output terminal. Additionally, the second amplifier provides feedback current with respect to the capacitor depending upon signals provided to the fourth and fifth input terminals. The capacitor and each of the amplifiers can be implemented on an integrated circuit without any need for external components.

    摘要： A method of calibrating a sensor such as a photodetector, and device capable of employing that method, are disclosed. The method includes shining light upon a photosensitive device of the photodetector, receiving a first signal from an operator, and increasing a gain of the photodetector. The method also includes discontinuing the shining of the light upon the photosensitive device after the gain has been increased, receiving a second signal from an operator, and decreasing the gain so that the gain is not excessive.
