Abstract: A decorative free-standing illumination tower for outdoor and aquatic environments is capable of being deployed in outdoors and aquatic environments without the need of an external support. The tower includes an elongated tube, a plurality of lighting fixtures, a light controller, a power source, a first endcap, and a second endcap. The plurality of lighting fixtures is mounted in a helical fashion around the elongated tube. Consequently, the plurality of lighting fixtures is positioned along a longitudinal axis and radially mounted around the elongated tube. The first endcap and the second endcap connect at opposite ends of the elongated tube. The light controller is an electronic device that controls the actuation of the plurality of lighting fixtures. Accordingly, the plurality of lighting fixtures can be made to display various patterns, images, and colors. Finally, the power source provides electrical power to the plurality of lighting fixtures and the light controller.

Abstract: A door check assembly comprises a guide block and a one-piece or multi-piece elongate linkage having a range of travel back-and-forth through the guide block between a first position and a second position corresponding to open and closed positions, respectively, of a door assembly incorporating the door check assembly. A locking pin or other check-lock member is mounted in the guide block for movement between a locking position and an unlocking position. A check-lock actuator, e.g., hand-operated, electric, etc., is operatively connected via linkage directly or indirectly (i.e., alone or in combination with other link members) connecting the check-lock actuator to the check-lock member. The check-lock actuator is mounted in a door at a position, e.g., remote from the check-lock in order to be more convenient for the user. The check-lock actuator is operative via the linkage member to move the check-lock member between the locking position and the unlocking position.

Abstract: Logic unit cells are disclosed, consisting of an array of high speed logic gates, the outputs of which are wired together and coupled to a low power driver. High speed and switching rates are achieved by using very fast logic gates which have no gain and make use of a wired logic function in order to effect two levels of logic without adding the propagation delay through another logic gate. These arrays of logic gates are coupled to drivers which restore logic levels and provide the necessary power for driving interconnect capacitances while consuming and dissipating a minimum of power in the process. Another logic circuit discloses an array of logic gates as inputs to another logic gate, the individual gates consisting of gallium arsenide components and having drivers built into the output stage of each gate.
