Abstract: An wireless audio transceiver housing comprising an air inlet, an intake manifold, one or more fans, directing vanes, and an exhaust port, wherein the geometry of the intake manifold, the directing vanes, and the exhaust port are configured to enhance airflow from the one or more fans through the housing, over a heatsink, and out the exhaust port towards the rear of the housing by minimizing the pressure drop for the one or more fans and maximizing the potential for airflow through the unit.

Abstract: A weatherproofed interconnection junction includes: a first cable having a first connector at one end; a second connector; a sealing cylinder with an internal cavity, wherein the first connector and second connector are joined and reside within the cavity; and an elastomeric sealing boot having a cable section and a connector section. The first cable is conformably received in the cable section and the sealing cylinder is conformably received in the connector section.

Abstract: An assembly includes: a hybrid power/fiber optic cable comprising pluralities of power conductors and optical fibers, the plurality of power conductors and the plurality of optical fibers contained within a common jacket; a first breakout canister; and a second breakout canister. The hybrid power/fiber optic cable enters the first breakout canister and a plurality of power cords exit the first breakout canister, the power conductors of the hybrid power/fiber optic cable and the power cords being electrically connected within the first breakout canister, a respective one of a plurality of first conduits protecting each of the plurality of power cords. The plurality of optical fibers enters the first breakout canister and exits the first breakout canister, the exiting plurality of optical fibers being protected by a second conduit attached to the first breakout canister. The plurality of optical fibers enters the second breakout canister and exits the second breakout canister.

Abstract: A dual function heating and toasting apparatus is provided for radiantly heating or surface toasting bread-type food products. The apparatus includes a housing defining a heating/toasting chamber. A generally vertically oriented, center fixed heating platen is disposed in the chamber. A pair of generally vertically oriented, movable heating platens are disposed on opposite sides of the center fixed platen. A gate is movably mounted on the housing near the bottoms of the platens for movement between a closed position to hold a product between the platens and an open position allowing a finished product to exit the chamber. A product such as a bagel can be placed into the chamber onto the gate between one of the movable platens and the fixed platen and spaced therefrom to heat the bagel by radiant heat. Alternatively, a product such as a bun can be placed in the chamber onto the gate and the movable platen moved to bias the bun against the fixed platen to surface toast the bun.

Abstract: An improved antenna system for transmitting and receiving electromagnetic signals comprising a backplane having a length and a vertical axis along the length. A plurality of dipole radiating elements project outwardly from a surface of the backplane. Each of the elements includes a balanced orthogonal pair of dipoles aligned at first and second predetermined angles with respect to the vertical axis, forming crossed dipole pairs. An unbalanced feed network extends along the backplane and connected to the radiating elements. A printed circuit board balun is attached to each of the dipoles. The antenna can also include a parasitic element positioned along the vertical axis such that primary electromagnetic fields induce currents on the parasitic element, these induced currents re-radiate secondary electromagnetic fields which cancel portions of the primary electromagnetic fields, thereby improving isolation.

Abstract: A spark-protected alternator has an external cavity on an end plate of the alternator housing with commutating (slip) rings on an alternator shaft extension and mating metal brushes positioned within the external cavity. The external cavity is effectively sealed from ambient atmosphere surrounding the alternator, to provide protection from sparks generated between the brushes and commutating rings wherein a minimum area of the housing end plate is utilized. Integral extensions of the end plate form side walls of the external cavity that partially radially surround the shaft extension and commutating rings. A brush holder in which the brushes are attached has projections which mate with slots in the side walls to radially close the external cavity, and an end cap (including a gasket) closes an open end of the external cavity, while the end plate effectively closes the other end of the external cavity.
