    摘要： A power monitoring and correction to a desired power level of a laser or group of lasers utilizes two photodetectors which are employed to accurately determine the amount of output power from the front end or “customer” end of a laser or a plurality of such lasers. During power detection, which may be accomplished intermittently or continuously, the laser is modulated with a tone of low frequency modulation. One photodetector at the rear of the laser is employed to detect the DC value of the frequency tone, i.e., a value or number representative of the AC peak-to-peak swing, amplitude or modulation depth of the tone. Also, the rear photodetector may be employed to determine the optical modulation index (OMI). In either case, these values may be employed in a closed loop feedback system to adjust or otherwise calibrate the value of the low tone frequency relative to the total desired bias current applied to the laser. A front photodetector is employed to receive a portion of the total output of the laser, or of each laser, and the average output power of the laser, or of each laser, is determined from already knowing the optical modulation index (OMI) via the rear photodetector. Thus, by measuring and/or calibrating the laser OMI with the use of a rear photodetector, the average output power from the front end output can be unambiguously determined from detection of the AC peak-to-peak swing or amplitude of the low frequency tone received via the front photodetector.

    摘要： Systems and methods of centralized product production, comprising a job initiation component that receives a job request from a user; a resource management component that delegates tasks to one or more modules to produce a product to meet the job request. The modules can comprise an automated computing system or a practice group, and can report back to the resource management component. An assembly component can receive information, documents, and objects from the resource management component and assemble the items to form a product. An interface component allows a user to view progress of the product, and to receive status updates.

    摘要： An apparatus for monitoring whether a cable is coupled to a port of a computer network. A free-running oscillator is initially set to a base frequency when a cable is not coupled to the port. If a cable is subsequently coupled to that port, the inherent capacitance of that cable loads one of the nodes associated with the oscillator. The result of this capacitance is that the oscillator is now running at a lower frequency. A frequency counter and threshold comparator are used to detect whether the oscillator frequency has fallen below a pre-determined frequency threshold. If the oscillator frequency has not fallen below this threshold, the port is not included in the network path. However, if the oscillator frequency has fallen below the threshold, this indicates that a cable has been coupled to the port. Consequently, the trunk port is inserted into the computer network's path.
