Patent number: 7132833Abstract: 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.Type: GrantFiled: March 29, 2001Date of Patent: November 7, 2006Assignee: Powerware CorporationInventors: David Layden, Craig Edevold, Cary Winch, Donald Zahrte, Sr.

Patent number: 6418024Abstract: 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.Type: GrantFiled: March 23, 2001Date of Patent: July 9, 2002Assignee: Powerware CorporationInventors: Craig Edevold, Cary Winch

Patent number: 6391489Abstract: 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.Type: GrantFiled: March 29, 2000Date of Patent: May 21, 2002Assignee: Powerware CorporationInventors: Cary Winch, Craig Edevold, Gregory Mears

Patent number: 6374460Abstract: 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.Type: GrantFiled: March 29, 2000Date of Patent: April 23, 2002Assignee: Powerware CorporationInventors: Craig Edevold, Cary Winch

Patent number: 6310783Abstract: 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).Type: GrantFiled: March 29, 2000Date of Patent: October 30, 2001Assignee: Powerware CorporationInventors: Cary Winch, David Layden, Craig Edevold

Patent number: 6292379Abstract: 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.Type: GrantFiled: March 29, 2000Date of Patent: September 18, 2001Assignee: Powerware CorporationInventors: Craig Edevold, Cary Winch, Donald K.
