Abstract: Various methods, apparatuses/systems, and media for automatically protecting sensitive information data entering application logs, events, metrics, traces, or other outputs are disclosed. A processor receives source code associated with an application being developed; parses the source code and identifies variables or fields in the source code that include sensitive information data; applies artificial intelligence or machine learning algorithm to the source code to automatically identify variables that contain the sensitive information data based on the identified variables or fields and annotating accordingly. Each annotation is a hint that data associated with corresponding annotation is confidential and sensitive information that should not be published, logged, or printed.

Abstract: In a computer system having multiple servers, services are coordinated among nodes as a result of each node tracking the node state of each other node (such as the services it currently performs) and performing coordinator functions (such as controlling which servers provide which services) only if it determines itself to be a coordinator node and only if all nodes are in agreement as to the node state of every node. Each node communicates, to each of the other nodes, its node state, a coordinator node identifier indicating which node it has determined to be the coordinator node, and a global state of all nodes it determines based on the node states and coordinator nodes of all the nodes. A node performs coordinator functions only if it is a coordinator node and only if all nodes have the same global state.

Abstract: Systems and methods for efficiently operating a gas discharge excimer laser are disclosed. The excimer laser may include a chamber containing laser gases, first and second electrodes within the chamber, and a plurality of reflective elements defining an optical resonant cavity. The method may include setting the laser gases to a first pressure; after setting the gases to the first pressure, applying a first voltage to the electrodes, thereby propagating a laser beam in the optical resonant cavity; measuring energy of the beam; adjusting the first voltage until the energy of the beam is substantially equal to a target pulse energy; operating the laser for an amount of time; after the amount of time, measuring energy of the beam; and changing the pressure of the gases to a second pressure different from the first pressure.

Abstract: A method and apparatus for laser cutting a target material is disclosed. The method includes the steps of generating laser pulses from a laser system and applying the laser pulses to the target material so that the laser pulses cut through the material. The laser pulses have an approximately ellipse shaped spot, have a temporal pulse width shorter than about 100 nanoseconds, and have an energy density from about 2 to about 20 times the ablation threshold energy of the target material. The laser pulses are applied to the material such that the major axis of the ellipse shaped spot moves parallel to the cutting direction. The spot has a leading edge and a trailing edge on the major axis, and the energy density of each laser pulse increases from zero to a maximum along the leading edge and decreases back to zero along the trailing edge.

Abstract: A shaped plasma discharge system is provided in which a shaped radiation source emits radiation at a desired frequency and in a desired shape. In one embodiment, a laser source provides an output beam at a desired intensity level to shaping optics. The shaping optics alters the output beam into a desired shaped illumination field. In an alternate embodiment, plural laser sources provide plural output beams and the shaping optics can produce a compound illumination field. The illumination field strikes a target material forming a plasma of the desired shape that emits radiation with a desired spatial distribution, at a desired wavelength, preferably in the x-ray, soft x-ray, extreme ultraviolet or ultraviolet spectra. In another embodiment an electric discharge generates the required shaped radiation field. The shaped emitted radiation proceeds through an optical system to a photoresist coated wafer, imprinting a pattern on the wafer.

Abstract: A portable laser device for obtaining blood samples through the skin of humans or animals. A laser crystal is optically pumped to produce a short high power laser pulse which vaporizes a small hole in the skin. The pulse is shaped to produce a pulse cross section at a sampling location which has a long dimension and a short dimension similar to a blade cut.
