Abstract: Described herein is a technique for surfacing content for users of a connection network application. The technique involves performing a first query to fetch recently-impressed items viewed by a user of the connection network application and, concurrently with the first query, performing a second query of search nodes to generate a set of search node results. The technique allows for filtering the recently-impressed items from the set of search node results to generate a candidate set and applying a freshness factor to the candidate set. Updates are provided to a user display, based on results of applying the freshness factor to the candidate set.

Abstract: A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

Abstract: A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller, with a motor geared to the drive roller. An automatic separator device is provided, wherein the drive roller conveys a leading lottery ticket to a separation position such that a line between the leading ticket and an adjacent ticket is presented to the separator device. The separator device includes a shuttle that travels in a linear path along the line, the shuttle having a head that engages and separates the leading ticket from the adjacent ticket along the line. A bi-directional drive mechanism moves the shuttle back and forth along the linear path.

Abstract: A failure of a head is detected, the head reading from and writing to an affected surface of a disk of a disk drive. The failure prevents the head from writing to the affected surface but does not prevent the head from reading from the affected surface. In response to detecting the failure, a remediation is performed. The remediation involves determining spare capacity blocks on other surfaces of the disk drive different than the affected surface, and copying data from the affected surface to the spare capacity blocks via an internal copy function within the disk drive. The spare capacity blocks in place of the affected surface for data storage and retrieval subsequent to the failure.

The inner cylinder being arranged to move along a longitudinal axis of the bore between a first condition and a second condition and is biased by a spring force to assume the second condition. A mechanical outstop is arranged to engage an abutment surface of the inner cylinder to limit extension of the shock absorber strut; and a rotatable member drives the out stop axially to move the inner cylinder from the second condition towards the first condition. The rotatable member is arranged such that the spring force cannot rotate the rotatable member to allow the shock absorber strut to extend.
