Abstract: An assistance device includes a body having two wheels, and a pivotal device located in the body. Two transmission units are pivotably connected to the pivotal device by two shafts. A restriction unit includes a first link, a second link and a rail which is connected to the body. The first link has the first end pivotably connected to one of the two transmission units. The second link is pivotably connected to the other one of the two transmission units. A roller is connected to the first end of the second link and movable along the rail. A leg having a top end to which the second end of the first link is pivotably connected. The second end of the second link is pivotably connected between the top end and the lower end of the leg. The leg contacts against the ground to lift the body to climb stairs.

Abstract: A jacket member for fitting on a pole of a resolver stator. Enameled wires can be wound around the jacket member to indirectly form coils on the pole of the resolver stator. The jacket member includes a hoop body for fitting on the pole of the resolver stator, whereby the enameled wires can be wound around the hoop body to form the coils. The jacket member further includes multiple projections disposed on the hoop body and projecting therefrom. After the enameled wires are wound around the hoop body, the terminals of the enameled wires can be hooked and located on the projections.

Abstract: A hiding structure for positioning signal conversion mechanism of a torque motor, which includes a stator having a curvature center line, a rotor coaxially fitted with the stator, a positioning/detecting section disposed on the stator between the stator and the rotor for detecting movements of the motor and outputting corresponding analog signals and a signal conversion section for receiving the analog signals provided by the positioning/detecting section and converting the analog signals into digital signals and outputting the digital signals. The signal conversion section is fixed on an end face of one end of the stator in an insulated state.

Abstract: A resolver unit including a first resolver and a second resolver. The first resolver includes a first rotor. A certain number of first rotor magnetic poles are annularly disposed on the first rotor at equal intervals. The second resolver includes a second rotor coaxial with the first rotor. A certain number of second rotor magnetic poles are annularly disposed on the second rotor at equal intervals. The number of the second rotor magnetic poles is different from the number of the first rotor magnetic poles.

Abstract: A multi-function printer is provided. A trigger piece is fixed to the first module and stretched into a second module. A wedging piece is disposed in the second module and protruded from the second module. An actuating piece and a join piece are disposed in the second module. The actuating piece has a first end connected to the actuating piece and a second end positioned close to the trigger piece. When the three modules are stacked together, the trigger piece goes against the wedging piece and the actuating piece goes against a third module. When the first module is rotated, the trigger piece is separated from the wedging piece such that the wedging piece can be wedge with the third module. When the second module is rotated, the actuating piece drives the joint piece to wedge with the trigger piece.

Abstract: The present invention relates to an improved structure of a treadmill, more particularly, to a frame structure of an electrical, collapsible treadmill. The frame structure includes a front frame assembly, a rear frame assembly and elevation mechanism disposed under the front frame assembly. The elevation mechanism includes a front leg assembly, a rear leg assembly and an elevation device, of which the front leg assembly and rear leg assembly are pivotally and slidably connected to each other, such that the elevation mechanism is able to support the front and rear frame assembly by means of scissors type supporting structures without the need of a base. When in use, the treadmill can be kept stable without the need of any extra fastening means; whereas when being stored, the treadmill can be folded by only flipping over the rear frame assembly upward. This design makes the convenience in storage and reduces the costs in assembling and manufacturing.

Abstract: A finger acupressure apparatus comprising a pair of upper and lower pressing plates configured with adjustable distance therebetween and at least one acupressure element on an inner side of the plates enabling for compressing against fingers or the palm muscle for physical therapy purposes.

Abstract: An exercise apparatus includes a support frame, a crank assembly, two swing units, and two pedal assemblies. The crank assembly is mounted on the rear of the support frame, and has a crankshaft and a pair of crank members. Each swing unit includes a lever mounted on the front of the support frame, and a longitudinal connecting unit connected to a respective crank member. Each pedal assembly includes a rocking arm with a pivot end mounted pivotally on the front of the support frame, and a pedal axle having a rear end making relative sliding movement with the connecting unit when the pedal axle is moved. The pedal assemblies are respectively connected to the swing units for swinging synchronously with the swing units.

Abstract: A protective ear shield releasably mounted over the top and the rear saddleback portion of an ear suitable for releasing discomfort due to compression pressure of the shield and the weight of the added body accessory. The protective ear shield comprises at least two curved sections joined with an adjustable connecting member for adjusting and fixing the distance between these two sections. The ear shield is configured to fit the contours of the top and the rear saddleback portion of the ear so as to minimize the discomfort feeling. The ear shield may comprise a hook element at each end of the two sections configured for securing the eyeglasses or sunglasses.
