Abstract: A composite headset is provided, including: two sound production modules, where the two sound production modules can be worn on both sides of the head of a user, and each of the sound production modules includes a moving-coil unit and a thin-film sound production element. The moving-coil unit is used to produce a first-frequency sound field, and the thin-film sound production element is used to produce a second-frequency sound field. The thin-film sound production element is an arc-shaped convex or concave sheet that is formed by being bent towards a sound output direction of the moving-coil unit.

Abstract: The present invention relates to a method for calculating optimal control force of an active mass damper and controlling the active mass damper, which is used for vibration control of a structure, the method comprising: (a) sensing frequency and an acceleration response generated in a structure in real time by a sensor, wherein the frequency and the acceleration response are structural responses; (b) calculating velocity and displacement of the active mass damper by integrating the acceleration response by an integral calculation module; (c) calculating the optimal control force using a weighting function and a zero point calibration signal according to the calculated velocity, the calculated displacement, and the calculated displacement, by a control force calculation module; and (d) controlling driving of an actuator according to the calculated optimal control force.

Abstract: A toilet comprises a toilet body. A water inlet end is disposed at a side of the toilet body. The water inlet end is connected to a water inlet pipe. The toilet body has a frame top, and a groove is formed downwardly along the frame top. A water outlet end is disposed on a bottom of the groove. The water outlet end is connected to a discharge pipe. A frame seat portion is formed at a top of a urinal. A flow deflector is extended downwardly from a back end of the frame seat portion. The frame seat portion is covered onto the frame top, and a front end of the frame seat portion is pivotally connected to a front end of the frame top of the toilet abody.

Abstract: An electro-heating hair curling apparatus includes a casing, a tube-shaped member, a rotatable assembly, a motor, a peripheral member, a first electro-heating device, a second electro-heating device and a control unit. The casing includes a handle part and a hair-accommodating part. The tube-shaped member and the peripheral member are disposed in the hair-accommodating part. When a length of hair passes through a breach of the hair-accommodating part to dispose in a space between the tube-shaped member and the peripheral member, the control unit selectively controls the motor to drive the rotatable assembly to engage the hair on the tube-shaped member and further to rotate and wind the hair around and onto the tube-shaped member. The control unit also controls the first electro-heating device and the second electro-heating device to heat and thus style the hair wound around the tube-shaped member.

Abstract: A mechanical, electrical and optical scanning apparatus for producing a digital image of a two-dimensional original object that can be either opaque or transparent. A platform supports a camera with precision zoom/focus control for receiving light energy from the object, and the light is converted into electrical energy in a digital format. Opaque objects are supported separately from transparent objects on a carriage, and a light source is supported pivotly for illuminating these objects during scanning in a different manner.

Abstract: A ball projecting apparatus includes a housing with a frontward opening. The interior of the housing has an elongated ball guider which extends inclinedly and longitudinally from a position near the frontward opening and which terminates at a lower position, an electrically driven rotor which is mounted below the elongated ball guider, and a torsion spring which is mounted pivotally to the housing. The torsion spring has a first end portion which engages by a stopper and a second end portion which extends into a circular path that is traveled by the rotor when the rotor is activated.

Abstract: A racket stringing apparatus includes a frame unit, a racket retaining device and a string tautening device. The string tautening device includes a string clamping unit, a swing lever and a counterweight mounted movably on the swing lever. A stringing receiving groove unit is formed in the top surface of the string clamping unit and has a non-clamping section and a clamping section. The non-clamping section has a fixed width, while the clamping section has a width which can be adjusted to clamp tightly a string therein. The string tautening device includes a limit member which has a first limit peripheral surface and a second limit peripheral surface. The swing lever has a lower end which normally abuts against the first limit peripheral surface so as to prevent the actuator end portion of the swing lever from turning toward the racket retaining device and to permit the actuator end portion to turn away from the racket retaining device until the swing lever contacts the second limit peripheral surface.
