Abstract:
Various conveyor designs are disclosed, along with related link designs, suitable for conveying objects along a transport direction. The conveyor may include a plurality of connected links. Each link may have a length extending across the direction of transport and a width extending along the direction of transport. Each link may have a body, a slider, at least one gripping member, and a gear drive mechanism interconnecting the slider and gripping member. The slider is slidable along the length of the body to selectively move the gripping member between a first position and a second position via the gear drive mechanism. The gripping member when in first position is disposed in an open position, and the gripping member when in the second position is disposed in a gripping position for contacting one of the objects to hold the object during transport. The gear drive mechanism may be a rack and pinion mechanism, the gripping member may have one or more gripping arms, and the gripping arms may or may not be offset from the gear drive mechanism.
Abstract:
A system includes an interference microscope having one or more optical elements arranged to image a test object to an image plane by combining test light from the test object with reference light from a reference object to form an interference pattern at the image plane, wherein the test and reference light are derived from a common broadband light source. The system includes a scanning stage configured to scan an optical path difference (OPD) between the test and reference light, a multi-element detector positioned at the image plane and configured to record the interference pattern for each of a series of OPD increments and to generate multiple interferometry signals each having a fringe carrier frequency indicative of changes in the OPD as the OPD is scanned, where there is phase diversity among the interferometry signals, and an electronic processor coupled to the multi-element detector and scanning stage and configured to process the interference signals based on the phase diversity to determine information about the OPD increments having sensitivity to perturbations to the OPD increments at frequencies greater than the fringe carrier frequency.

The apparatus also includes an electronic processor electronically coupled to the detection system and scanning stage and configured to determine information about the OPD increments with sensitivity to perturbations to the OPD increments at frequencies greater than the frame rate.
Abstract:
An administration server in a database management system retrieves log files in a plurality of formats from a plurality of clients through helper programs running on the clients. The plurality of clients can include Web servers, application servers, and database servers. The log files can be generated by software modules on the clients. An administration engine converts log entries in the log files into a unified format for display. The converted log entries can be stored in a log database. Upon a user request, the administration server presents the log entries to the user in a log viewer. The log viewer can display log entries originated from heterogeneous software modules in a unified view.

Abstract:
An administrator can specify a script sequence including one or more system scripts and database scripts. A graphical user interface is provided to allow the administrator to specify an execution order of individual scripts in the script sequence and a timeout interval for when the script sequence will complete. Once the script sequence is specified, the script sequence can be run without further intervention by the administrator.
