  • Patent number: 10971786
    Abstract: A cell stack includes adjacent first and second battery cells respectively having a positive cell tab, a negative cell tab, and an outer surface. The outer surfaces are flush. The positive cell tab of the first battery cell protrudes from the outer surface of the first battery cell, and the negative cell tab of the second battery cell protrudes from the outer surface of the second battery cell. An isolative shield is positioned adjacent to the outer surfaces, and defines through-slots receiving therein a respective one of the cell tabs. A method includes providing the cell stack, inserting the cell tabs into the pair of through-slots of the isolative shield, positioning a primary surface of the isolative shield adjacent to the outer surfaces of the adjacent battery cells after inserting the cell tabs, and affixing the primary surface of the isolative shield to the cell stack.

  • Patent number: 9050898
    Abstract: A battery module includes two or more battery cells and a continuous wave fin disposed between the battery cells. The construction of the wave fin is generally one-piece such that fewer parts are needed to form the battery module. In a preferred form, the wave fin is made from a high thermal conductivity material to promote removal of heat generated by the batteries during their operation. Portions of the wave fin not in direct contact with the battery cells may be placed in direct contact with a heat sink to help remove excess heat from the module. Expansion units or related additional structure may be placed, along with the various battery cells, between the generally serpentine-shaped wave fin to provide uniformity in cell spacing. A method of making one or more battery modules is also described.

  • Patent number: 7209964
    Abstract: In a telecommunications switching network having a resource complex including network switches, an intelligent service platform for providing intelligent call processing and service execution for call events received at the switches and requiring call processing services. A centralized administration system is provided that comprises a system for storing one or more reusable business objects that each encapsulate a distinct call-processing function, and any associated data required by the business object; a system for distributing selected business objects and associated data to selected nodes in the switching network based on pre-determined node configuration criteria; and, a system for activating the business objects in preparation for real-time use. A computing platform is provided within each node for executing those business objects required to perform a service in accordance with an event received at the network switch.

  • Patent number: 6788649
    Abstract: An intelligent network implementing processes and apparatus for supporting ATM/Vnet services. The intelligent network comprises the ability to receive an ATM VNET call at an ATM switch associated with a service node of the intelligent network, translate the dialed VNET number and then extend the call to a correct termination. Prior to the outdial, source address and subscription validation, destination address screening, source address screening and VNET number translation are performed. In one embodiment, assuming that the VNET call is an ATM to ATM call, no number translation is required. In placing Vnet/ATM calls, the network does all resource allocation, e.g., bandwidth reservation and allocation. The resource specification in the ATM setup message (e.g., bandwidth) is validated against the customer's subscription versus the current network utilization.

  • Patent number: 6393481
    Abstract: System and methodology for providing real-time call processing services received at a switch in an intelligent network having one or more service nodes having originating switches for receiving a call event. The system includes a platform-independent communication system for enabling communication between object instances executing at service nodes in the intelligent network. An operating system agent object instance executing in an execution environment associated with an originating switch communicates call origination information corresponding to a call event received at the switch to one or more object instances executing in an execution environment provided at a service node in the network; the object instances including a line object instance for maintaining the state of a communications line associated with a call origination, and, a service object implementing methods for performing a service according to a customer request.
