The present disclosure provides a device and method for powder distribution and an additive manufacturing method, wherein different size or kind of powders could be chosen to be accommodated within a receptacle. The receptacle can uniformly mix the powder by a rotation movement, pour out the powders by the rotation movement and distribute the powders for forming a layer by a translation movement. In another embodiment, the receptacle further comprises a heating element for preheating the powders. Not only can the present disclosure uniformly mix the powders so as to reduce the thermal deformation and distribute the powder layer compactly, but also can the present disclosure distribute different kinds of powder in different layer so as to increase the diversity in additive manufacturing.

A limb prosthesis including a palm, a forearm, an upper arm, an elbow joint and a wrist joint is provided. The palm has a first pivot and a first lock set. The upper arm has a socket. The elbow joint connects the forearm to the upper arm. The wrist joint includes a first connecting rod connected to the forearm. The first pivot rotatably penetrates through the first connecting rod. The first lock set is locked to the first pivot. A first wedge surface of the first lock set contacts a second wedge surface of the first connecting rod. By adjusting a distance between the first lock set and the first pivot, a magnitude of a forward force between the first wedge surface and the second wedge surface is adjusted, such that the palm is fixed relative to the first connecting rod or rotatable around an axial direction perpendicular to an extending direction of the forearm.

An implant device for osseous integration includes a plurality of connection bars and at least one frame bar. These connection bars are connected with each other to form a three-dimensional (3D) grid structure. The frame bar is connected with at least two of the connection bars to define at least one edge of the 3D grid structure. Wherein, the frame bar has a diameter substantially greater than that of these connection bars.

An electromagnetic transmission device. A guide bar connects to a fixed base and includes magnetic-permeable material and a first central height plane. A coil connects to the fixed base. A support base movably fits on the guide bar. An annular magnetic member connects to the support base and is surrounded by the coil. A magnetization direction of the annular magnetic member is perpendicular to a moving direction of the support base and annular magnetic member. The annular magnetic member includes a second central height plane. The coil interacts with the annular magnetic member to generate a first force. When moving to separate the second central height plane from the first central height plane, the annular magnetic member interacts with the guide bar to generate a second force, driving the support base and annular magnetic member to move along a direction perpendicular to the magnetization direction of the annular magnetic member.

An apparatus and a method are proposed for measuring displacement, surface profile and roughness of a moving object or an inner radius of a hollow cylinder. The apparatus includes a light emitting unit, a light dispersing unit for receiving light from the light emitting unit and focusing rays with different wavelengths into different focal points with different intervals, and a wavelength measuring unit for measuring wavelengths of the rays. When the moving object is moving within a dispersing range of the focal points, the rays with different wavelengths are reflected or scattered, and the displacement of the moving object is learned from variation of the wavelengths being measured by the wavelength measuring unit. Given that a reflecting component is disposed in the centre of an inner circle of the hollow cylinder, the inner radius of the hollow cylinder can be measured by the principle of the apparatus for measuring displacement.

A voice coil motor. A guide bar connects to a fixed base. A coil connects to the fixed base and includes a first winding portion and a second winding portion. A current direction in the first winding portion is opposite that in the second winding portion. A support base movably fits on the guide bar.

A high power LED has at least a porous material layer, a thermal conductive layer and a chip. The thermal conductive layer is disposed on the surface of the porous material layer and the chip is disposed on the thermal conductive layer. Heat generated by the chip is conducted from the thermal conductive layer to the porous material layer, and convected outside via the porous material layer. Thereby, surface area in contact with the air is increased and high thermal conductivity and high heat convection are also achieved.
