摘要:
An all-weather housing for outdoor microwave radio nodes arranged in a network, each node capable of directing or receiving a beam of microwave energy in a selected direction, the housing including a shroud enclosing a transceiver, antenna, switches, and utilities. Each shroud has a radome projecting from the shroud in line of sight relation to other radomes in the network. A microwave radio transceiver is disposed within the shroud, operating on a scheduled transmission and reception basis in accordance with a schedule provided in a control channel amidst data. A ball-shaped microwave refractive lens is located adjacent to the radome, inside of the shroud, with a curved array of feed ports and switches, with the feed ports communicating microwave energy between the transceiver and the radome through the lens in multiple selected directions.

Embodiments of luer-type needle-free valve devices are disclosed. One of the novel aspects of the invention is its ability to transform from an open state to a closed state. The open position eliminates the potential for a differential pressure to exist between the volume connected to the inlet and outlet of the valve fitting. The closed position enables the device to maintain a differential pressure between the volume connected to the inlet and outlet of the valve fitting. The invention is useful in manufacturing sterile medical devices by allowing all surfaces to communicate with the sterilizing agent when the valve is in an open configuration when it is in a closed position.

The junction box of the present invention allows a user to couple multiple electronic devices to a primary electronic device. The junction box includes a housing assembly made up of an upper housing and a lower housing. The upper housing fits over the lower housing so as to form an enclosure. A seal assembly forms a seal between the upper housing and the lower housing. The upper housing extends outward on one side so as to form an overhanging portion and an opening. The overhanging portion, along with the seal assembly prevents fluids, dust and foreign particles from entering the enclosure. A circuit board is disposed in the enclosure that is coupled to a primary electrical cable. The primary electrical cable connects to the back of a primary electronic device. Electronic devices that are to be coupled to the primary electronic device are coupled to the junction box via cables that connect to each electrical device and connect to the circuit board. These electrical cables extend through the opening and under the overhanging portion of the upper housing.
