Abstract: The present invention provides an adjustable dorsal splint for resolving the shortcomings of a typical fixation splint. The invention includes a fixation splint, which contains a splint body, a first retaining portion, and a second retaining portion. A curvature adjustment portion is placed at a preset location of the splint body of the fixation splint, so as to adjust the splint body into predefined bending angle. As the fixation splint is provided with a curvature adjustment portion, it is possible to flexibly adjust the bending angle of the fixation splint to mate with the foot of the patient, thereby maintaining the position of the feet with better efficiency.

Abstract: The present invention provides a kind of high-rigidity light-weight rehabilitation walking. The boots include a foot support, two leg supports and two strengthening pieces. The foot support is made of plastics, having a bottom surface and two lateral edges. The two lateral edges are configured with slots, and there is a contact surface on top of the slots. The leg supports are made of plastics, having a stretch support, an insert and a restriction edge between the stretch support and the insert. The restriction edge can push against the contact surface on top of the slot. The strengthening pieces are buried inside the leg supports with its upper part within the range of the stretch support and its lower part within the range of the insert to strengthen the leg support structure and increase capacity of the rehabilitation walking boots to withstand side force.

Abstract: An adjustable light-modulating device includes: a light valve disposed to receive colored light provided by a color separator of a projection display apparatus, and capable of modulating the colored light; an adjusting mechanism including a fixing frame to be disposed between the light valve and the color separator, and a mounting frame coupled rotatably to the fixing frame; and a securing unit for securing the light valve to the mounting frame. The fixing frame defines a first hole, and has a first periphery surrounding the first hole. The mounting frame defines a second hole registered with the first hole, and has a second periphery surrounding the second hole. The adjusting mechanism further includes a guide projection formed on one of the first and second peripheries and projecting toward and contacting slidably the other one of the first and second peripheries.

Abstract: An adjustable light-modulating device for a projection display apparatus including a color separator capable of providing colored light includes a light valve and an adjusting mechanism. The light valve is disposed to receive the colored light provided by the color separator of the projection display apparatus, and is capable of modulating the colored light. The adjusting mechanism includes a mounting frame to be disposed between the light valve and the color separator, and a securing unit for securing the light valve to the mounting frame such that the light valve is linearly displaceable and tiltable relative to the mounting frame.

Abstract: A light processing module includes a light modulator with a liquid crystal panel, and a dust protection member. The dust protection member includes a base frame, and first and second frame elements. The base frame has a color separator mounted therein. The light modulator is mounted spacedly on a component mounting side of the base frame. The first frame element is disposed between the light modulator and the component mounting side, and has a frame opening to receive the liquid crystal panel. The second frame element is disposed between the first frame element and the component mounting side, and has a frame opening to receive a wave plate. The dust protection member permits formation of a dustproof chamber between the liquid crystal panel and the wave plate, and adjustment of the wave plate relative to the color separator.

Abstract: An engaging device for disposing a wheel to an axle of a golf cart includes a disk member fixedly connected to the wheel and having a recessed portion defined therein. An oblong hole is defined through the disk member. An actuating plate is movably received in the recessed portion and has a recess defined in a lower edge thereof. A shoulder portion extends inwardly from an inner periphery defining the recess. A lever extends laterally from a side of the actuating plate. A biasing member is disposed to the disk member and biasedly presses the lever downwardly. The axle extends through the wheel, the recess and has an annular groove defined in a periphery thereof so that the shoulder portion is disengagably received therein.
