This invention provides an apparatus for detecting a touching position on a flat panel display, including a display panel for displaying text and picture information, an electrically-controlled swing element with the angle of swing thereof being controlled by an electrically-driven actuator, a light source with a light beam thereof being reflected onto a display plane of the display panel or an upper or lower plane proximate to the display plane by the electrically-controlled swing element, an optical system with the optical axis thereof being parallel to the display plane, and a photo-sensing element disposed at an image plane of the optical system. A one-dimensional position of a touching point on the display panel is obtained from the photo-sensing element. Another one-dimensional position of the touching point is obtained from the said one-dimensional position and the angle of swing of the electrically-controlled swing element.

Apparatus for detecting a touching position on a flat panel display and a method thereof

This invention provides a photographing module with optical zoom, which at least includes a focusing lens assembly, a zoom lens assembly, a focusing lens actuator, a zoom lens actuator, a photo sensor and a vibration sensor. The focusing lens actuator at least includes a first movable member, a first fixed member and a first electric unit, wherein the first electric unit can drive the first movable member to proceed axial displacement and incline at an angle with respect to at least one axis. The zoom lens actuator at least includes a second movable member, a second fixed member and a second electric unit, wherein the second electric unit can drive the second movable member to proceed axial displacement. Alternatively, the axial inclination driven by the first electric unit of the focusing lens actuator may be driven by the second electric unit of the zoom lens actuator.

This invention provides a photographing module at least including: an electric drive assembly comprising a movable member, a holder, a magnetic circuit system and an elastic member, wherein the magnetic circuit system comprises at least three magnets and at least three coils so as to drive the movable member to perform a linear movement with respect to the optical axis and an angle of inclination with respect to at least an axis, and a magnetic pole direction of each magnet is perpendicular to the optical axis, an axis with respect to the coil winding axis of each coil is perpendicular to the optical axis; a photo sensor positioned on an image side of the photographing module and connected to the holder of the electric drive assembly; and a vibration sensor at a proper position of the photographing module capable of detecting directions and magnitude of a vibration.

Photographing module

A driving circuit for a photographing module includes a load comprising three coils and four signal input ends; a power source configured to drive the coils and capable of providing an intermediate level between a supply voltage level and a ground level; and a set of electronic switch elements. The driving circuit controls the magnitudes and directions of the electric currents flowing through the coils by switching the set of electronic switch elements, thereby enabling the photographing module to perform auto-focusing and compensate for an angle of inclination.

A foot-immersing massaging machine includes a body and an immersing vessel combined on the body. The body has a housing, a motor, a switch, a power cord, and a vibrator. The vibrator is fixed on an upper end of the shaft of the motor, and produces vibration when rotated by the motor. The immersing vessel has a vessel body and a soft massage cushion. The vessel body has a through hole in the bottom center for an upper portion of the vibrator to extend through upward, and the massage cushion is placed on the bottom of the vessel body and closes up the through hole, covering the vibrator with a gap between itself and the vibrator. Then a user can put the feet in the immersing vessel and receive massage performed by the vibrator at the same time.

A cooking device having an outer pot and an inner pot removally suspended in the outer pot is proposed for better and easier cooking of foodstuff. The inner pot is made of thermally conductive, metallic material and is adapted for initially cooking foodstuff with a separate heater for a short period of time. The outer pot is made into a thermally insulated construction and adapted to house the inner pot containing the semi-cooked foodstuff in the outer pot in a thermally insulated manner, so as to allow the semi-cooked foodstuff to complete the cooking by its own latent heat without a further heating by an external heat supply means.

High temperature adiabatic cooking device

A speed adjusting mechanism for adjusting the speed of an endless belt of a treadmill includes a speed variable V-belt drive mechanism which has two pairs of cone-shaped discs mounted coaxially on a transmission shaft disposed between an output shaft of a motor and a driven shaft of the treadmill belt. Each pair of discs includes a fixed disc and a slideable disc adjacent to the slideable disc of the other pair of discs, and the slideable discs slide mutually upon lateral displacement of the transmission shaft. The transmission shaft is displaced laterally by a reversible motor through a crank mechanism and a gear mechanism including a sector gear. The slope of the belt is adjusted by another reversible motor through a gear mechanism including a sector gear.
