Abstract: A cable backplane system includes a backplane having board areas surrounding a connector opening with holes in the board areas along the connector opening. Stiffeners are coupled to corresponding board areas along a front of the backplane. The stiffeners have bores aligned with corresponding holes in the backplane. A cable rack is coupled to the rear of the backplane. The cable rack has a tray with a frame surrounding a raceway and spacers coupled to the tray that hold corresponding cable connectors. The spacers have guide pins extending therefrom that pass through the holes in the backplane into corresponding bores in the stiffeners to position the spacers relative to the stiffeners and the backplane. The cable connectors are received in the connector opening in the backplane and held in position relative to the backplane by the spacers and stiffeners.

Abstract: A cable backplane system includes a backplane and a cable rack coupled to the backplane. The cable rack includes first and second trays having first and second frames. A plurality of cable connector assemblies are held by the cable rack each having a plurality of cables extending between a first cable connector and a second cable connector. The first cable connector is coupled to the first frame and the second cable connector is coupled to the second frame with the cables routed in first and second raceways of the first and second trays. Float mechanisms are connected between the first and second frames that allow limited movement between the first and second trays. The float mechanisms allow alignment of the cable connectors with corresponding openings in the backplane.

Abstract: An electrical connector system includes a panel having a plurality of connector openings and a plurality of vent openings interspersed among the connector openings. Cable connectors are coupled to the panel and extend at least partially into the connector openings. The cable connectors have mating interfaces presented at the front for mating with mating connectors and the cable connectors have cables extending from cable ends of the cable connectors and located rearward of a rear of the panel. Air funnels are coupled to the panel at corresponding vent openings. The air funnels extend rearward of the rear of the panel. The air funnels route the cables clear of the space rearward of the vent openings to define an unimpeded flow path through the vent openings.

The plates each include a hem folded over at a rear of the plate. The hem has an edge positioned rearward of the cable connectors and supporting the cable connectors from retreating from the openings in the backplane.

Abstract: A cable backplane system includes a backplane having a plurality of openings therethrough. A cable rack is coupled to a rear of the backplane, which includes a tray and spacers coupled to the tray that have guide pins. Cable connector assemblies are held by the tray. Removable dust caps are coupled to corresponding cable connectors each having a distal end and guide walls extending therefrom that guide mating of the cable rack with the backplane. The distal end of each dust cap is received in a corresponding opening in the backplane. The guide walls guide the cable rack relative to the backplane such that the guide pins of the spacers are aligned with guide holes of the backplane and such that the cable connectors are aligned with the openings of the backplane. The removable dust caps are removed after the cable rack is coupled to the backplane.

Abstract: An energy storage system having one or more battery packs and a system controller for controlling the battery packs. Each battery pack has rechargeable storage cells and a battery pack controller in communication with the system controller. Through the operation of the system controller, battery packs with different initial charge states can be operated in parallel during a charge process and a discharge process. Discharging multiple battery packs in parallel offers not only a higher capacity and a longer run time than is available from a single battery pack, but also offers higher peak currents than available from a single battery pack, which are important in motor control applications. A battery pack design including a battery pack connector with both power and control contacts supporting user replacement of the battery packs.

Abstract: A cable backplane system includes a backplane having a plurality of openings extending between a front and a rear of the backplane. The backplane has mounting locations proximate the openings. Mounting blocks are coupled to the front of the backplane at corresponding mounting locations. The mounting blocks are secured to the backplane by fasteners. A cable rack is coupled to the rear of the backplane and has a tray with a frame surrounding a raceway and spacers coupled to the tray. The spacers hold corresponding cable connectors and are secured to corresponding mounting blocks to position the spacers and cable connector assemblies relative to the backplane. The cable connectors are received in corresponding openings in the backplane and are held in position relative to the backplane by the spacers and mounting blocks.

Abstract: Improved protection for a rechargeable battery from damage by being discharged below a cut-off voltage is provided. The measured voltage of a battery under load is lower than the measured voltage of the battery under no load. As the cut-off voltage for the battery is specified as a no load voltage, comparing the measured voltage of the battery under load to the cut-off voltage would result in stopping use of the battery with useable charge remaining. Through testing, a set of relationships for estimating the no load voltage of a battery under load has been determined. Using this set of relationships with battery measurements, an estimated no load voltage for the battery is determined. This estimated no load voltage is compared to the cut-off voltage. This allows for full use of the battery while stopping use of the battery when its voltage reaches the cut-off, thereby preventing damage.

Abstract: The present invention optimizes storage of stream file by dynamically adjusting the size of new extents. In one embodiment, a file system manager collects usage statistics for a plurality of files in a file system. The file system manager uses the usage statistics to create larger extents for frequently used files than for infrequently used files.
