Abstract: A monitor stand comprising a base, a bracket, and an arm assembly, is discussed. The arm assembly is movably coupled to the base and movably coupled to the bracket. The bracket is configured to support a monitor. The arm assembly is configured such that an action to rotate the arm assembly relative to the base is coupled and operable to proportionally rotate the bracket relative to the arm assembly.

Abstract: A printed circuit assembly carrier comprises a carrier frame configured to hold a selected printed circuit assembly of at least two different printed circuit assemblies in at least two different orientations, a first toolless retention feature coupled to a first surface of the carrier frame and configured to retain the selected printed circuit assembly, and a second toolless retention feature coupled to a second surface of the carrier frame and configured to secure the carrier frame in at least one of the orientations.

Abstract: The sender of a multicast in a computer network attaches an official release time to the message being multicast, asking every receiver to process the message at or after the official release time. A receiver may receive a cancellation notice after receiving the multicast message but before its official release time. The official release time is chosen so that the multicast can succeed or be cancelled by the official release time with the probability at or above a user selected level under reasonably bounded numbers of occurrences of permanent and temporary faults and reasonably bounded durations of temporary faults. This multicast protocol is formulated to suit the environment where it is not worth it for a node to wait for a reply from another node beyond a certain time-period, called the timeout period.

Abstract: Systems for mounting electronic components are provided. An exemplary system includes a module that is configured to mount to a chassis at a first pitch. The module incorporates a housing, which is adapted to at least partially encase an electronic component, and spring fingers that are arranged at least partially about an exterior of the housing. The spring fingers are configured to deflect in response to a displacement force so that the module can be mounted to a chassis. The module can be mounted to a first chassis that accommodates a predetermined pitch of modules. In some embodiments, the module also can be mounted at a different pitch. Other systems also are provided.

Abstract: This invention relates to an improvement in a method for manufacturing dipeptides by coupling N-blocked aspartic acid and a phenylalanine lower alkyl ester in a medium containing a water-miscible organic solvent mixture in the presence of an immobilized metallo-protease so that a continuous reaction is established with stable enzyme activity.
