Abstract: Apparatus and methods for effecting therapy on a body using an electric/magnetic or an electromagnetic field is disclosed herein generally having a housing defining a reservoir for receiving a portion of the body at least partially within an electrically conductive medium. A portion of the reservoir contains at least one positively charged electrode and at least one negative charged electrode secured to the housing by a retaining member. The apparatus may also comprise of a magnet in proximity to the electrodes. The electrodes induce a static or a fluctuating electric field which is regulated by a controller unit such that the electric field is perpendicular to the magnetic field to impart a resulting force which may act upon the user's body to effect therapy. The electric current may be further regulated by measuring a physiological parameter and correlating the electric and/or magnetic field strength according to the measured physiological parameter.

Abstract: A brilliance control apparatus of light source in an optical scanner particularly contemplating for a transparency scanner includes a generally rectangular lamp stand and a lamp shade which has an asymmetrical curvature surface and has a black reflector with a curved surface disposed therein. And is capable of performing filtering and darkening processes at the same time.

Abstract: A switching device for a multi-lens optical scanner, which comprises a body casing, a sliding lens seat and a driving mechanism; the feature of the switching device is that the power of a scanning device is used for driving a guide rod of the switching device so as to set the mechanism at a given position automatically, and provide an optical scanner with various resolving powers desired.

Abstract: An improved transmission system for a document feeder, in which a constant one-way-rotating gear train is mounted in an output zone so as to cause a transmission shaft in the output zone to rotate in one direction only to send out a sheet of document no matter the driving gear rotates clockwise or counter-clockwise; therefore, as soon as a first sheet of document moves out of the scanning line without moving out of the output zone, the driving gear will change its rotation clockwise so as to have a next sheet of document fed into the scanning zone; therefore, the feeding distance between two sheets of document will be reduced, and consequently the whole feeding time for a document will be reduced, too.

Abstract: An improvement of brightness compensation for a lamp shade in an optical scanner includes a plurality of projections to make a reflector in the lamp shade to form a greater curvature on its lateral sides, thus increase the light-condensing capability of the reflector, and thereby improve brilliance uniformity of a lamp tube.

Abstract: A lamp shade moving mechanism for transparency scanning includes a guiding rack, a sliding block, a driving motor and a belt. Grooves are formed on inside wall of two lateral sides of guiding rack to hold and lead sliding block. Driving motor and belt move sliding block to make a linear to-and-fro movement along guiding rack. A lamp shade is disposed on the sliding block, characterized by having simple components and capable of performing high speed scanning.
