Abstract: A battery pack includes an outer housing having an open top, an outer housing lid applicable to the open top to define a closed outer hold within the outer housing, and a power port carried on the outer housing. The battery pack includes an inner housing within the outer hold of the outer housing, which inner housing includes a basin and an inner housing lid applicable to the basin to define a closed inner hold within the inner housing. A plurality of battery cells are disposed entirely within the inner hold, wherein the battery cells are electrically coupled to the power port to provide power to the power port.

Abstract: A standby solution for extended run time power systems for a load at a telecom site with backup power includes an interface distribution module including a battery bus, a lithium battery electrically connected to the battery bus, a charging rectifier electrically connected to the interface distribution module. The standby solution has a line mode, wherein the charging rectifier maintains a constant maximum voltage level of the lithium battery, a discharge mode, wherein the interface distribution module engages a discharge bias to enable discharge of the lithium battery to the load, and a charge mode, wherein the interface distribution module disengages the discharge bias to disable discharge of the lithium battery.

Abstract: A battery pack including a rectangular prismatic outer housing including a front and a back, opposed sides, a bottom and an open top, and a lid applied to the open top to define a closed outer hold within the outer housing. The battery pack further includes a power switch, a power port, an input/output, and a display all carried in the front of the outer housing. An inner housing is within the outer hold of the outer housing and includes a basin and a lid applied to the basin to define a closed inner hold within the inner housing. A plurality of battery cells are disposed entirely within the inner hold, and the battery cells are electrically coupled to the power port to provide power to the power port.

Abstract: A gasket for concrete structures such as tunnel segments includes a gasket body having a bottom face configured to be positioned against a surface of an associated tunnel segment. The bottom face may include a set of spaced indentations. First and second anchor members protrude from opposed side edges of the gasket adjacent the bottom face of the gasket. The anchor members are configured to attach the gasket to the tunnel segment during casting of a precast concrete member. The gasket body forms a groove in the concrete member and the anchor members form side channels in the groove. A respective fin can be provided on opposed side faces of the gasket. Should a defect be found in the original gasket, the gasket body can be removed from the groove of the concrete member relatively easily, even in the field, and a replacement gasket having corresponding anchor members, fins and indentations, can be snapped into the groove.

Abstract: A cast-in-place gasket construction for concrete structures such as tunnel segments includes a gasket body having a bottom face configured to be positioned against a surface of an associated tunnel segment. First and second gasket portions of the construction extend in different directions and are connected to each other at a first joint. The gasket portions are made of an elastomeric material having a first durometer on the Shore A hardness scale. The joint comprises an elastomeric material having a second and lesser durometer on the Shore A hardness scale. A method for replacing a damaged frame-like gasket construction is also disclosed.
