Abstract: A method and apparatus for transmitting acknowledgements in response to data packets in wireless communication are disclosed. A recipient may receive a plurality of data packets from a plurality of stations and transmit acknowledgements for the data packets to the originating stations in a single transmission. The acknowledgements may be transmitted using multi-user multiple-input multiple-output (MU-MIMO). Alternatively, the acknowledgements may be aggregated and transmitted in the single transmission. A short acknowledgement (ACK) frame may be sent in response to a received frame. The short ACK frame may include an ACK sequence corresponding to a sequence identity (ID) included in the received frame. The short ACK frame may include a short training field (STF) and the ACK sequence. The short ACK frame may be transmitted with a short ACK indication. The short ACK frame may be sent in response to an indication included in the received frame.

Abstract: Methods and systems are provided for creation and implementation of firewall policies. According to one embodiment, a firewall maintains a log of observed network traffic flows. An administrator may request the firewall to generate a customized report based on the logged network traffic by extracting information from the log based on specified report parameters. The report includes aggregated network traffic items and one or more corresponding action objects. Responsive to receipt of a directive to implement an appropriate firewall policy for one or more network traffic items based on interaction with one or more action objects by the administrator, the firewall then automatically defines and establishes an appropriate firewall policy.

Abstract: Methods and apparatus, including computer program products, related to relationship-based authorization. In general, data characterizing a request for authorization to a computer-based resource is received, and the authorization may be provided based on one or more relationships of a requesting principal. A determination may be made as to whether a requesting principal is authorized, which may include determining whether the requesting user has a relationship with a principal that has management rights of the computer-based resource and determining whether the relationship allows for an access, such as a use of the computer-based resource, if the requesting principal has a relationship with the other principal. If there is no such relationship, a determination may be made as to whether an organization of the requesting principal has a relationship with the other principal that allows for the access.

Abstract: Techniques for facilitating and accelerating log data processing are disclosed herein. The front-end clusters generate a large amount of log data in real time and transfer the log data to an aggregating cluster. When the aggregating cluster is not available, the front-clusters write the log data to local filers and send the data when the aggregating cluster recovers. The aggregating cluster is designed to aggregate incoming log data streams from different front-end servers and clusters. The aggregating cluster further sends the aggregated log data stream to centralized NFS filers or a data warehouse cluster. The local filers and the aggregating cluster stage the log data for access by applications, so that the applications do not wait until the data reach the centralized NFS filers or data warehouse cluster.

Abstract: A system and method for setting agent cross skill enablement levels in a contact center. In one embodiment, a series of simulations is performed to determine optimum cross skill enablement levels for various circumstances, e.g., the number of agents, the proficiency of each agent at each of a number of skills, and the rates of incoming interaction requests requiring each of various skills. A lookup table is created which is subsequently used, during configuration of the contact center prior to operation, or in real time during operation, to adjust agent cross skill enablement levels.

Abstract: A system for programming integrated circuit (IC) dies formed on a wafer includes an optical transmitter that outputs a digital test program as an optical signal. At least one optical sensor (e.g., photodiode) is formed with the IC dies on the wafer. The optical sensor detects and receives the optical signal.

Abstract: A snubber apparatus comprises a casing defining an inner cavity. A shaft passes through the inner cavity and rotates about its longitudinal axis. The shaft has one or two ends laterally projecting out of the casing and being connected to a moving part of a tool to dampen given motions thereof. A wiper arm is on the shaft so as to rotate therewith the shaft, with a free end in close proximity to the surface portions of the inner cavity. The free end has an arcuate contour complementarily corresponding to a circumferential surface portion. A dam extends from the circumferential surface portion into close proximity to the wiper arm, to divide the inner cavity in two chambers, with movements of the wiper arm changing the volume of the chambers. A hydraulic circuit controls a flow of fluid between chambers to oppose a force to rotation of the shaft.

Abstract: A media restraint for a removable media tray and slidably operable without the use of a pinching force. The media restraint slidably positionable on a track in a removable media tray and is operable without pinching. A pair of latching cams are used to engage the media restraint to the track and have serrated portions pivotally mounted to a bottom of the media restraint. The media restraint is operable by a finger of the user applying a downward force to the media restraint allowing a rack and pinion to horizontally translate a rack portion of the pair of latching cams away from the track and pivot the serrated portions away from the track and allowing the media restraint to be moved along the track. Upon removal of the downward force, a biasing member translates the latching cams back to reengage with the track.
