Abstract: A method of handling a plurality of session requests at an access manager may include assigning a rank to each of a plurality of agents. Each of the plurality of agents may forward requests for protected resources to the access manager for authentication and/or authorization, and the access manager may establish a plurality of sessions. The method may also include establishing a first session that is associated with a first agent in the plurality of agents that is assigned a first rank, a first user device, and/or a user credential. The method may additionally include receiving a request to establish a second session that is associated with a second agent in the plurality of agents that is assigned a second rank, a second user device, and/or the user credential. The method may further include determining whether the second session should be established.

Abstract: Systems and methods are disclosed for using a global unified session identifier across data centers. When a user first accesses a data center and an initial session is created for the user in the data center, a session identifier is generated for the user session. Because the initial session is the first session created for that user, the initial session identifier is designated as the global unified session identifier for all sessions that may be created for the user in other data centers within the enterprise network. Other data centers may then map the global unified session identifiers to locally generated session identifiers for the user. Using a global unified session identifier enables various user session actions to be performed globally across the data centers, including global logout, global session termination, global session updates, and/or the like.

Abstract: Systems and methods are disclosed for a single sign-on (SSO) enterprise system with multiple data centers that use a lightweight cookie on a user's client device. The lightweight cookie includes a reference to a data center in which the user is already authenticated, and a new data center contacts the old data center for creating a session for the user on the new data center. If the old data center is unavailable, then the new data center may fall back to accessing a local security store, a backup of keys, security tokens, and/or other security data, in order to create a local session for the user on the new data center.

Abstract: A method of dynamically communicating a parameter during runtime may include providing a script to a command-line scripting module that uses the parameter, where the parameter is to be provided during runtime by a user and the script is configured to generate an exception including an identifier associated with the parameter. The method may also include generating byte code based on the script, executing the byte code on a virtual machine until the exception is generated, passing the exception to the command-line scripting module, causing, by the command-line scripting module, receiving a parameter value from the user through an input device, passing the parameter value to the virtual machine, and continuing execution of the byte code on the virtual machine.

Abstract: A vehicle tire includes tread blocks positioned on the tire. One or more rotating sipes are formed in each of the tread blocks. Each rotating sipe comprises first and second walls that are substantially parallel wherein the first wall includes three points that lie in an imaginary plane and a fourth point that lies outside of the imaginary plane.

Abstract: Tire having a tread pattern with superior performance characteristics. The tread pattern includes ribs and circumferential grooves which are at least one of tapered and/or generally V-shaped. The walls of each circumferential groove have a wavy and/or sinusoidal contour extending in a generally circumferential direction.

Abstract: A tire tread has a decoupling groove (32) with walls (20, 22) that have a wavy shape in the radial direction with respect to the tire geometry, i.e. at least one axial deviation (26, 28) along the depth of the decoupling groove (18). An axial cut through the tire tread (10) divulges a wavy course of the decoupling groove (18), where the two walls (20, 22) have contours that complement each other. During a road contact of a respective tread section, the decoupling groove (18) closes, and a radially interlocking connection between the shoulder rib (12) and the decoupler rib (14) is made. Under load, the decoupler rib (14) functions like a part of the tread (10), thus protecting the shoulder rib (12) from erosion wear.

Abstract: In a tire tread with a decoupling groove (38), the edge (36) of the tread rib (32) adjoining the decoupling groove (38) has a wavy contour. The wavy edge (36) provides protection from step-off wear because erosion at one location is confined to the affected wave. The adjacent edge (44) of the decoupler rib (34) may have a complementary wavy contour. In the area of the contact patch, where the vehicle load on the tire deforms the tread, these two edges (36,44) will interlock with each other, thus protecting the outer edge (36) of the tread rib. Instead, the outer edge of the decoupler rib (34) will be subjected to erosion wear. Toward the bottom of the decoupling groove (38), the wavy contour of the edges (36,44) may taper off. The bottom of the decoupling groove (38) can be arranged in a straight circumferential line.

Abstract: A tire tread (1) includes tie bars (13,14,15,16) in its secondary grooves (9,10,11,12). These tie bars (13,14,15,16) are rounded and taper off on their sides so that the contour of such a tie bar (13,14,15,16) in cross-section along a groove (9,10,11,12) constitutes a continuous curve without edges or straight lines. The profile of the tie bar (13) is essentially a circle segment with sides leveling off toward the bottom of the groove (12). This design allows a gradual change in block stiffness unlike conventional tie bars, which only provide a sudden drop-off in block stiffness.

Abstract: A tire tread has a decoupling groove (18) with an opening angle (?) of approximately 15°. Even if gravel is moved into the groove (18) by the decoupler rib (14), it will easily fall out once the tread section loses touch with the road surface and the groove (18) expands to its relaxed shape. Additionally, the ridge (24) of the decoupler rib (14) is rounded with a radius (R2) of about 2 mm. By this means, it has a much lower tendency to pick up rocks by scooping when bending toward the shoulder rib (16). A rounded bottom of the decoupling groove (18) with a radius (R1) of approximately 1.5 mm, will prevent any rocks from wedging into the bottom of the decoupling groove (18).

Abstract: A compressed air system and method of operating the system wherein the slip between the compressor motor and its powering alternator is used as an indication of whether the compressor is running in a loaded or unloaded mode. A slip parameter such as % Slip is determined and compared to an allowable value in real time. If the compressor is determined to be erroneously in a loaded mode, a corrective action may be taken to reduce the probability that the motor is later started with the compressor still in the loaded mode.
