Abstract: A housing containing a rotatable cage for rotatably supporting a spherical flow control valve having a vertically orientated open or filled conduit and an internal bottom weight mass centered on the vertical conduit. If the rotatable cage is tilted, the gravity-responsive bottom weight mass rotatably maintains the control valve conduit in a vertical orientation. If the cage is walled, the rotating cage wall will travel over the ends of an open conduit to form a seal, which effectively occludes any gas, liquid or electromagnetic beam flowing through the conduit. If the cage is open and rotatably supports the valve via annular supports, the rotating cage will interrupt an electromagnetic beam or electric current flow through the control valve conduit. The flow control valve may also have an extended open or filled conduit which may be provided with an additional weight mass, or a magnetic mass associated with a locking ring.

Abstract: A multimodal pointer method, comprising an elongated, graspable, control shell (301) which has a rotatable, multi-axis control ball encoder (302) positioned so that it may be used in multiple modes, with a minimum of two function keys (307, 308) that can be used in all modes. The device may either be used at various orientations in-air, or be used in-air against a surface, or may be used downward on a side on a surface and used as a mouse, or be alternately used upward on a side as a trackball, and, in a preferred embodiment, may be used upright on its base (335), or on a cooperative static or dynamic, surface or suspension base stand (339, 338) which introduces other cooperative features.

Abstract: A small-scale portable recyclable fluid flushing method used for flushing irritants or inflammatory agents from the skin or eyes, or for flushing infectious debris from wounds. The invention is either made reusable or disposable, and typically comprises: a. a single or plurally chambered container with at least one flushing fluid chamber filled with an uncontaminated flushing fluid appropriate for the intended flushing procedure; b. a first outflow fluid conduit, e.g., a channel or tube, which transports uncontaminated fluid from the container flushing fluid chamber to a pump or impeller housing; c. a manual or electrically operated pump or impeller for transporting uncontaminated fluid through to a second outflow fluid conduit to a dispersal outlet or nozzle; d. a fluid runoff collector surrounding the dispersal outlet, or a catch basin situated below the dispersal outlet, either of which acts as a sump to capture the contaminated runoff fluid from the flushing procedure; e. a first drain fluid conduit; f.
