Abstract: A system of power transmission to a contact lens comprises a contact lens and a magnetic component. The contact lens comprises at least a physiological signal sensing component, an induction coil, and an energy storage component. When the magnetic component has a motion relative to the induction coil, an induced voltage is produced in the induction coil for charging the energy storage component.

Abstract: An impedance-to-digital converter is provided. A sensible impedance range of the impedance-to-digital converter is adjustable by changing magnitudes of signals inputted thereto.

Abstract: A water ball decoration includes a plug, which has an annular outer wall fitted into a lower end neck-shaped opening of a water-containing ball-shaped part, and an annular inner wall within the outer wall; a bottom is connected to the lower end of the inner wall to define a containing room. The annular inner wall is provided with corrugated surfaces on both the inner and the outer sides which will reduce the effect of the pressure of the inside of the ball part on the outer wall of the plug provided for tight connection with the opening. A hollow cone-shaped part is fitted into the containing room with an upper wider portion thereof being connected to the upper end of the inner wall; a space is provided between the narrower end opening and the bottom of the plug; thus air bubbles can be confined in a space between the outer side of the cone-shaped part and the inner side of the inner wall by means of turning the ball decoration upside down slowly and moving same back to the original position.

Abstract: A water globe arrangement includes a fluid pump immersed in a fluid within the fluid-containing glass dome, the fluid pump drawing fluid in through a fluid inlet and expelling the fluid through a fluid outlet, thereby circulating the fluid and creating a visual movement effect within the glass dome. In one aspect of the invention, a glass dome is filled with water and contains a number of small free particles having a specific gravity greater than that of the water. Upon activation of the fluid pump, a continuous flow of circulating fluid keeps the free particles in constant motion within the glass dome. In another embodiment of the invention, the fluid pump forces fluid within the glass dome along an elongated passageway coupled to the pump fluid outlet for directing the flow of fluid to a location remote from the fluid outlet.

Abstract: A watertight revolving device for rotating an ornamental object within a water globe that includes a base and a glass dome. The ornamental object has a vertical shaft extending down through a sealing gasket, through a rubber plug, and bent into a notch in a first coupling member. The first coupling member has holes for receiving upright bars of a second coupling member to fit therein. The first coupling member is attached to the rotatable ornamental object, and the second coupling member is attached to a revolving musical movement. The rubber plug has its annular wall provided with an annular projection, or rib, to engage the inner surface of a glass dome projection. The sealing gasket and rubber plug ensure a secure structure for preventing water from leaking out of the glass dome. One or more annular hard plastic members may be provided to reduce rotational sliding friction between the revolving and stationary components.

Abstract: A leakage preventing structure for water ball decorations includes an reinforcing ring fitting and rotated to fix in an anti-leak rubber plug combined in a lower portion of a glass dome filled with a liquid and a decorative figure placed in the glass dome of the water ball decoration. Then the reinforcing ring properly ring properly expands and forces the anti-leak rubber plug contact tightly the glass dome so as to strengthen preventing function of liquid leakage from the glass dome.
