Abstract: A strain wave gear includes a wave generator configured to contact a spline, the wave generator being rotatable. The strain wave gear also includes a coupler configured to couple a driver shaft to the wave generator. The coupler permits displacement of the driver shaft relative to the strain wave generator.

Abstract: A system and method for authorization policy evaluation. Authorization policies are authored in a general-purpose authorization language. An evaluation engine is used in a provider network by application developers to manage access within their applications based on fine-grained permissions. The policy language combines elements of role-based and attributed-based access control within an intuitive syntax and efficient evaluation strategy. The policy syntax separates role-based expressions of a policy from attribute-based expressions of the policy.

Abstract: A system and method for authorization policy validation. A validator takes as input an authorization policy to be analyzed and a schema that specifies entity types and their attributes, types of entity parents in an entity hierarchy, and which entity types can be used with which actions. The validator checks that the policy conforms to the schema. If the check passes, then the policy is guaranteed to be free of both type errors and attribute access errors for any input that conforms to the schema.

Abstract: A drive system for an actuator comprises first and second motors, and first and second input shafts connected to be driven by the respective first and second motors. Each of the first and second input shafts comprises a first overrunning clutch configured to rotate with the input shaft in a first direction, and a second overrunning clutch configured to rotate with the input shaft in a second direction. A first drive gear is configured to be driven by either one of the first overrunning clutches, and a second drive gear is configured to be driven by either one of the second overrunning clutches, and an output clutch and an output shaft are arranged to be driven by the first drive gear in a first mode of operation of the drive system and be driven by the second drive gear in a second mode of operation of the drive system.

Abstract: A graph structure provides a representation of source code and includes a plurality of nodes to represent a plurality of pointers within the source code, a plurality of type edges connecting nodes in the plurality of nodes within the graph structure (to identify a flow of a program to be implemented using the source code), and a plurality of checked edges based on respective usage of pointers in the plurality of pointers. A system determines, from the graph structure, whether one or more of the plurality of pointers comprise wild pointers based on one or more of the plurality of checked edges, and further determines, from the graph structure, pointer types for at least a portion of the plurality of pointers based on one or more of the plurality of type edges.

Abstract: A lock arrangement comprises a first jaw component (28) pivotally moveable about a pivot axis (12), a second jaw component (30) releasably securable to the first jaw component (28) to form a pivotable jaw assembly (10), and an actuator arrangement operable to drive the jaw assembly from a locked position to a released position.

Abstract: An optical fiber cable management panel is provided with slideable drawers and structure within the drawers for cable management and/or connection to other devices. Tray inserts drop into the drawers to provide the appropriate management and connection devices. A movable take-up mechanism manages the cable entering and exiting the drawers at side openings. Stackable pivoting storage trays on the tray insert include a detent arrangement for holding each tray in a pivoted access position. The tray inserts further include a front key, and a back tab mounting arrangement for mounting the tray inserts to the drawers, and side radius limiters including notches for extending over raised portions of the drawer. The take-up mechanism includes a U-shaped trough section and cable retention tabs. A control mechanism is provided for controlling movement of the take-up mechanism relative to the drawer.

Abstract: A cable clip includes a housing defining an open space and outer grooves about the housing for mounting the cable clip into a mounting opening, the inner edge of the housing including trumpet flares around the edges of the ends and side to provide bend radius protection for cables passing through the clip and a gate closing off the open sided space. The gate may be attached to the housing by a living hinge.

Abstract: In an improved approach to mounting optical elements in a fiber optic device, the positioning and orientation of the element are more accurate and the temperature dependent variations of the position and orientation are reduced. The mount has a protruding tip contact region on a mounting surface. Adhesive is supplied between the optical element and the mounting surface, and the optical element is pressed into contact with the protruding contact tip region, substantially expelling the adhesive from between the optical element and the protruding contact tip region. The adhesive is cured at a temperature exceeding the predetermined temperature range. This permits the adhesive to pull the element on to the contact tip region throughout the operating temperature range. This also permits the optical element to contact the mounting surface so that the optical element's surface is oriented parallel to the mounting plane.
