Abstract: An object stage bearing system can include an object stage, a hollow shaft coupled to the object stage, and an in-vacuum gas bearing assembly coupled to the hollow shaft and the object stage. The in-vacuum gas bearing assembly can include a gas bearing, a scavenging groove, and a vacuum groove. The gas bearing is disposed along an inner wall of the in-vacuum gas bearing assembly and along an external wall of the hollow shaft. The scavenging groove is disposed along the inner wall such that the scavenging groove is isolated from the gas bearing. The vacuum groove is disposed along the inner wall such that the vacuum groove is isolated from the scavenging groove and the gas bearing.

Abstract: The present invention provides a tubular linear actuator, comprising: a tubular coil assembly comprising multiple tubular coils arranged next to each other in longitudinal direction of the tubular linear actuator and concentric with respect to a longitudinal axis of the tubular linear actuator, and a magnet assembly comprising a series of permanent magnets with alternating polarization direction extending in the longitudinal direction, wherein the magnet assembly is at least partially arranged in the coil assembly and movably with respect to the coil assembly, wherein the tubular coils comprise edge windings.

Abstract: In an embodiment, an apparatus comprises one or more processors and a computer-readable storage medium storing one or more sequences of instructions which, when executed by the processors, cause the processors to perform generating relationship information based on relationships between one or more events that are generated by one or more managed systems. The computer-readable storage medium further comprises instructions which, when executed, cause sending the relationship information to the managed systems, wherein the relationship information allows the managed systems to determine whether reporting of the events, by the managed systems, should be suppressed; and receiving, from one or more managed systems, a report about an event when reporting of the event cannot be suppressed.

Abstract: A computer configured to serve data services in a one-way cable plant having telco-retum for upstream data resources to requesting computers in a networked environment is disclosed. The computer includes a subscriber edge services manager server and a radius proxy server, the radius proxy configured to classify received radius requests into a plurality of types and handle requests classified as a first type from requests classified as non-first types. The computer also includes an access point, the access point providing communication connection to at least one computing device. The subscriber edge services manager server and radius proxy server are configured to communicate with the access point to acquire information from the access point, and user location information is configured on the access point in a vendor-specific attribute.
