The present invention relates to an optics assembly having a platform and removable and interchangeable modules, and in particular to an optics assembly for a Kalashnikov style firearm. In one embodiment, the assembly has two ends with a longitudinal axis there between. The base replaces the rear sight tower of the Kalashnikov style firearm. The base has a platform with edges overhanging relieved areas or slots. The base has a head with holes there through. Modules can be removably received upon the base. Each module has at least one mount for supporting an optic. Each module has ears that straddle the base head. The ears have holes that are alignable with the head holes for receiving a pin. The modules have ribs that are received within slots in the base as the module is slid along the longitudinal axis relative the base.

An electrical cabinet for an uninterruptibe power supply (UPS) system includes universal slots that can receive power modules, battery packs, or chargers. The back plane of the slot has connector terminals for battery packs and power modules. The cabinet can be easily reconfigured as desired by changing the number of power modules chargers or battery packs installed. Circuitry is provided that indicates the capacity and operational readiness of the cabinet. This circuitry monitors the battery packs in each slot, and isolates any detected fault to a particular pack.

A heat sink apparatus for drawing heat from one or more devices and a method of attaching such a heat sink to one or more devices is provided. The heat sink includes a mounting surface, which draws heat into the heat sink where it is dissipated by fins. The heat sink can be mounted next to the device to be cooled with minimum insertion force since the weight of the heat sink is borne by the printed circuit board upon which the electronic device is installed. A rotatable cam is turned by the user, which engages a pivot arm. The pivot arm rotates a number of spring clips against the device thereby holding it in place. Onceina fully closed position, the cam locks into place to prevent the pivot arm and spring clips from rotating back to an open position. The spring clips affix the heat sink and maintains contact between the mounting surface and the device being cooled. The individually articulated spring clips allow the heat sink to be mounted over multiple devices of various dimensions and locations along the heat sink.

A battery terminal jumper clip is presented that is capable of providing series battery connection between adjacent batteries in a battery stack useful for an uninterruptible power supply. The battery terminal jumper clip accommodates tab type terminal connectors and utilizes a single piece unitary construction. Once inserted to provide series coupling between adjacent batteries, the battery terminal jumper clip prevents inadvertent removal by providing a snap-on locking surface for the tab terminal connectors. Lateral removal is also inhibited via axial retention surfaces on either side of the battery terminal jumper clip. A bus surface provides a current path between adjacent tab connectors in the series coupling, and mechanical connection is insured through the provision of at least tab retention clip. Relative vertical movement between adjacent batteries is accommodated by providing two tab retention clips, one for each tab terminal connector, and may be enhanced by providing multiple constituent retention clip segments for each tab terminal connector. A auxiliary connection terminal may be included to provide easy access for diagnostic equipment. This auxiliary connection terminal may be integrally formed in a top bus surface, or may alternatively be formed on an edge.

Provided is a multi-function, single-piece handle and modular electronic component incorporating same, and a method of inserting and removing the handle from the modular electronic component. The unitary structure of the handle includes insertion and extraction claws that aid in the insertion and extraction of the modular component from a rack mount upon rotation of the handle to an upward, and vertically extended position respectively. The handle also includes a stowage locking mechanism that maintains the handle in a stowed position on the front of the modular component. A rack locking mechanism is also provided integral with the handle to secure the modular component in its rack mount position. Affirmative user actuation is then required to allow the modular component to be removed therefrom. Outrigging mounting and support legs are also included to add rigidity and strength to the handle to allow it to be used to carry the modular component. By design, the handle may be inserted and removed from the modular component without the use of any tools, and is secured in place without the requirement of any additional hardware.

An electrical cabinet or chassis for an uninterruptible power system (UPS system) includes universal bays or slots that can receive either power modules or battery backs. The back plane of the slot has separate connector terminals for battery packs and power modules. The slots may also receive battery chargers if so desired. All of the slots of a chassis can be utilized to full capacity before another cabinet needs to be employed. The cabinet is also readily adaptable and can be easily reconfigured as desired without particular concern as to the number of power modules or battery packs that are being used. Sensors are provided which indicate the capacity of the cabinet that has been used (e.g. the number of slots still open and not used by a power module or a battery pack). The sensors also indicate whether a battery pack, power module or other device is inserted into the slot, and whether it is properly inserted, thereby providing an indication of the specifications of the UPS system as presently configured to the user.

Modular method and apparatus for building an uninterruptible power system (UPS)

A modular uninterruptible power supply is presented having multiple power modules installed therein. Each of the individual power modules contains an internal bypass circuit sized for its particular power module. Preferably internal bypass circuitry is sized to carry two per unit load. The system and method of the invention also includes internal control circuitry for each of the modular power modules that control transitions between the inverter and bypass modes of operation. This transition control is coordinated with the other controllers for the other modular power modules installed in the uninterruptible power supply. Both the high speed communication bus and a high level interrupt line are utilized to minimize the transfer break time between different modes of operation while ensuring that the inverter is never paralleled with the utility line voltage. To further minimize this transfer time, a solid state switching circuit is utilized to provide the initialization between operational modes. To maximize the efficiency during the bypass mode of operation, and electromechanical relay is utilized in coordinated operation with the solid state switching device to provide long-term power requirements during the bypass mode.
