Abstract: An alignment system having long term stability in illumination center wavelength is discussed. The alignment system includes a tunable radiation source and a feedback control system. The tunable radiation source includes a light source configured to provide a broadband radiation beam and a tunable multi-passband filter configured to filter the broadband radiation beam into narrow band radiation beam having a center wavelength value. The feedback control system is configured to measure the center wavelength value of the narrow band radiation beam and compare the measured center wavelength value with a desired center wavelength value. The feedback control system is further configured to generate a control signal based on the comparison in response to a difference being present between the measured center wavelength value and the desired center wavelength value and tune the tunable filter based on the control signal to eliminate or substantially reduce the difference.

Abstract: The unique identifier (UID) boot system provides a system and method for booting a network connected processing system. Briefly described, one embodiment is a method comprising receiving a UID, the UID uniquely identifying the network connected processing system; determining a directory structure from a first portion of the UID, the directory structure identifying a memory location in a network accessible memory wherein a UID script file resides, the UID script file comprising additional script that causes the network connected processing system to retrieve at least one resource information file; and determining a file name from a second portion of the UID, the file name identifying the UID script file.

Abstract: Composition of matter useful as an active mass of positive electrodes for a lead acid storage cell has an X-ray diffraction pattern substantially as shown in the. Figure. The matter is formed from lead-cadmium deposits using a methanesulfonic acid electrolyte system and pulse current.
