Abstract:
A compact lens module includes a lens seat, a lens group, a first and a second circuit boards. The lens seat includes a top surface, a bottom surface opposite to the top surface, and a first side surface connecting the top surface to the bottom surface. The lens seat defines a receiving space extending through the top surface and the bottom surface, and a receiving groove on the first side wall. The lens group is received in the receiving space. The first circuit board is mounted on the bottom surface of the lens seat, and holds an image sensor aligned with the lens group. The second circuit board is received in the receiving groove. The second circuit board holds a lens drive circuit and electrically connected with the lens group and the first circuit board.
Abstract:
A walker with armrests has a pedestal including a first side frame, a second side frame and two bridging rods connecting between the first and second side frames to form a stable structure to the walker. The two side frames each has two foot rods and a top lateral rod extending between the two foot rods. Two armrests are mounted on the top lateral rods of the first and second side frames, respectively. Thereby, a physiotherapy patient may rest his armpits on the armrests to avoid leaning forward when holding the top lateral rods of the walker.
Abstract:
A crutch has a pad, two bow rods connected to the pad downward, a handpiece connected to the bow rods transversely, a bolt and a butterfly nut fastening the handpiece and the bow rods together, a spring having two ends inserted through the bow rods, a sleeve having a through hole receiving lower portions of the bow rods, a pipe receiving the lower portions of the bow rods, the pipe having a taper end and a plurality of through apertures, and a tip cushion receiving the taper end of the pipe.
Abstract:
A lens module includes a lens holder, a liquid crystal lens, wires, and a driving unit. The holder includes an outer surface, a first end portion adjacent to an object side, and a second end portion adjacent to an image side. The first end portion and the second end portion are at opposite sides of the holder. The outer surface connects the first end portion to the second end portion. The holder defines wire grooves in the first end portion and the outer surface. The liquid crystal lens is received in the first end portion. The wires are formed on the first end portion and the outer surface in the grooves. The wires are electrically connected to the liquid crystal lens. The driving unit is electrically connected to the wires and drives the liquid crystal lens to zoom.
