Abstract: An RF power combiner. A plurality of RF inputs connect to a power combiner switch assembly. RF switches connect each input to a common node. A single stub matching circuit connects between the common node and an output node such that an open-ended transmission line stub extends from the output node. An RF output connector feeds an RF output connection from the output node. The stub of the L-match circuit has fixed length or variable length configurations. As a consequence, the impedances at the common and output nodes are more closely matched.

Abstract: A power combiner circuit for RF signals includes a multi-path network for conveying a plurality of RF signals over a selected path or paths, to a common node. A switched RF impedance transformer connects between the common node and an RF load. The switched RF transformer switches between first and second transformation functions depending upon the number of network paths that are selected.

Abstract: Disclosed is a battery system in which a battery is provided with a pair of quick connect electrical contact mechanisms. A battery tray, for receiving the battery, is also provided with a pair of quick connect electrical contact mechanisms which are adapted to connect and establish electrical continuity with the battery quick connect mechanisms. The battery pin assemblies may be molded into the battery cover and may be welded to the existing positives and negative battery posts. In this manner, the provision of the pins requires no additional penetrations of the battery container, thus reducing the potential for leakage of electrolyte from the container. The pins may be nested within indentations provided in the container. In this manner, the provision of the pins adds only minimally to the overall dimensions of the battery, thus resulting in a compact design.

Abstract: Disclosed herein is a venting mechanism for a battery. The venting mechanism includes a battery vent structure which is located on the battery cover and may be integrally formed therewith. The venting mechanism includes an opening extending through the battery cover such that the opening communicates with a plurality of battery cells located within the battery case. The venting mechanism also includes a vent manifold which attaches to the battery vent structure. The vent manifold includes a first opening which communicates with the battery vent structure opening and second and third openings which allow the vent manifold to be connected to two separate conduits. In this manner, a plurality of batteries may be interconnected for venting purposes, thus eliminating the need to provide separate vent lines for each battery. The vent manifold may be attached to the battery vent structure by a spin-welding technique.

Abstract: An electrical terminal connector is disclosed for use in an electrochemical cell. The terminal connector includes a first terminal member made from metal inert to the environment within said cell and adapted for interfacing internally within the cell. The first terminal member includes a socket portion communicating with the exterior of the cell. The terminal connector also includes a second terminal member made from low electrical resistance metal and is adapted for engagement within the socket portion from the exterior of the cell.
