Abstract: Systems for maintaining light sources for semiconductor photolithography in which a module making up part of the light source is evaluated at various pulse counts to produce a binary prediction as to whether the module is sufficiently likely to operate without failure in an ensuing sequence of pulses. The binary prediction may be made by a machine learning model trained on metrics extracted from measurements taken on deinstalled modules. A group of models, each trained differently, can be made available according to a selection made by the user or according to the maintenance objectives of the user.

Abstract: A subject support (14) is configured to dock with a medical imaging device (50) with a fixed spatial relationship between the docked subject support and the medical imaging device. A patient positioning device includes a range camera (10) that acquires a two-dimensional (2D) range image of a human imaging subject (12) disposed on a subject support (14). The range image has pixel values corresponding to distances from the range camera. An electronic processor (16) is programmed to perform a positioning method to determine a reference point on or in the human subject in a frame of reference (FS) of the subject support from the 2D range image. This reference point is translated to a frame of reference (FD) of the imaging device based on a priori known spatial relationship of the medical imaging device and the docked subject support. Using 3D models, the loading process may be simulated.

Abstract: According to an example of the present disclosure, a system is disclosed. The system comprises at least one sensing unit and a robotics engine in communication with the at least one sensing unit. The at least one sensing unit detects stock information associated with an item. The robotics engine performs a trend analysis based on the stock information collected over a predefined duration of time, and determines a threshold value based on the trend analysis. Furthermore, the robotics engine generates an alert when the stock information is below the threshold value, and selects a vendor based on one or more predefined parameters. The robotics engine also generates an instruction to obtain the replacement item from the selected vendor for replenishing the item in an inventory.

Abstract: Methods and systems for determining overlay error between different patterned features of a design printed on a wafer in a multi-patterning step process are provided. For multi-patterning step designs, the design for a first patterning step is used as a reference and designs for each of the remaining patterning steps are synthetically shifted until the synthetically shifted designs have the best global alignment with the entire image based on global image-to-design alignment. The final synthetic shift of each design for each patterning step relative to the design for the first patterning step provides a measurement of relative overlay error between any two features printed on the wafer using multi-patterning technology.

Abstract: A system which enables an administrator to conveniently specify statements of a web page description which may require additional processing. The administrator may select from a list of statement types, and a language grammar corresponding to the selected statement type is displayed. The administrator may provide variable data associated with the fields of the displayed language grammar, and a rule instance is created from the language grammar and the variable data. An intermediate server may determine whether each statement of a web page description matches any of the rule instances. If a match is detected, the corresponding statement is determined to potentially require additional processing (such as modification of a URL in a reverse proxy server).

Abstract: An approach which enables the overhead of performing a task associated with performing a procedure (function) call to be shifted to clients from a reverse proxy server when the reverse proxy server forwards web pages, the content of which may be dynamically created on the clients according to a description (e.g., using Java Script Language). The reverse proxy server may include instructions associated with the description to re-define the procedure call such that the task (in addition to the logic of the pre-defined procedure call) is performed on the clients. For example, with reference to a procedure call containing a URL accessible only within an intranet, the reverse proxy server may insert instructions which cause each client to insert the URL of the reverse proxy server such that any requests for a resource (corresponding to the URL) are passed through the reverse proxy server.
