Abstract: A computer-implemented and executed method of managing recorded video events is disclosed. The method collects viewer measurement data from presentation devices, the viewer measurement data indicating user viewing behavior associated with playback of recorded video events. The method continues by analyzing the collected viewer measurement data to estimate boundaries between segments of the recorded video events, which results in groups of estimated boundaries corresponding to the recorded video events. Cue files are generated for the recorded video events, the cue files indicating the estimated boundaries corresponding to the recorded video events. The cue files are maintained at a central system for access by the presentation devices.

Abstract: A rack apparatus used for retaining a workpiece having at least one threaded hole, includes a hanging frame, and at least one clamping assembly fixed on the hanging frame. Each clamping assembly includes a plurality of latching members and a plurality of connecting members detachably assembled on the latching members. Each connecting member includes a screw portion. At least one screw portion is engaged in a corresponding threaded hole of the workpiece.

Abstract: A turnover mechanism is used for turning a fixture and a workpiece positioned on the fixture, which includes a support bracket, a first turning mechanism, a movement mechanism, and a second turning mechanism. First turning mechanism includes a first rotary driver, a first clamping driver and two first clamping members oppositely positioned on the first clamping driver. The first rotary driver is positioned on the support bracket and connected to the first clamping driver. The first clamping driver drives the first clamping members to clamp the fixture and the workpiece. The first rotary driver rotate the first clamping driver and the two first clamping members to such that the fixture is driven to be rotated on a reverse side. The movement mechanism reaches the first turning mechanism to transfer the workpiece to the second turning mechanism. Second turning mechanism is mounted on the support bracket, clamping and turning the workpiece.

Abstract: A mounting apparatus for securing a data storage device (10) defining a number of fixing apertures (101) includes a bracket assembly (20), and a number of resilient gaskets (30). The bracket assembly comprises a first bracket (210), and a second bracket (220). The first bracket comprises a bottom panel (211), and a side panel (212). The second bracket includes a vertical plate (222) secured to the bottom panel of the first bracket. A number of positioning strips (204) some with a tab (206) extend perpendicularly from the bracket assembly to position the resilient gaskets respectively. The vertical plate is resiliently and outwardly moved to sandwich the data storage device in the bracket assembly. The data storage device is secured with the tabs engaging with the fixing apertures thereof.

Abstract: A computer enclosure includes a chassis (10) having bottom, side and rear panels (20, 30, 40), and first and second mounting brackets (50, 60) attached to the chassis. The bottom panel forms a rib (21). The rear panel defines a horizontal opening (42) and an engaging portion (44). Latch slots (32) are defined in the side panel. The first mounting bracket includes a vertical expansion slot (53), a bent plate (54) and a blocking tab (55). The second mounting bracket includes: a top plate (61) having latches (612) engaging in the latch slots, and catches (613) sandwiching a top edge portion of the rear panel; and a rear plate (62) having horizontal expansion slots (621), a hook (622) slidably engaging with the bent plate, a stop plate (626) abutting against the engaging portion, a stop portion (625) abutting against the rib, and a projection (624) engaging with the blocking tab.

Abstract: A disk drive mounting assembly includes a chassis (16), a first receiving cage (20), a mounting bracket (50) and a second receiving cage (60). The disk drive (10) comprises two pairs of sliding posts (12). The first cage for receiving the disk drive is generally U-shaped and has two side walls (23, 24). Each side wall defines a pair of slots (26, 32) for accommodating the sliding posts of the disk drive. The mounting bracket (50) pivotably attached to the first cage includes a pressing body (52) and a pair of fixing arms (54) depending from the pressing body. Each fixing arm defines a fixing cutout (56) for restraining the sliding posts. The second cage is attached to the chassis on the mounting bracket to prevent the disk drive from moving in vertical directions.

Abstract: A forming apparatus includes a workbench and a pivot device. The pivot device includes a pivot plate (40) and a fixed plate (60). The pivot plate is fixed below the workbench, and rotatably seated on the fixed plate. The fixed plate defines two cutouts (66) respectively in two corners thereof, to form an arched-shaped top portion (61). Three locking plates (70) are attached on side walls (42, 46) of the pivot plate. When the locking plates are oriented vertically, they can pass over the two corners corresponding to the cutouts but cannot pass over other corners of the fixed plate. When the locking plates are oriented horizontally, they can pass over every corner of the fixed plate. By adjusting orientations of the locking plates, the combined base and pivot plate can be rotated within a variety of predetermined different angles.
