摘要： A lens module includes a lens barrel, and a lens group received by the lens barrel. The lens barrel includes an first supporter, a second supporter extending vertically from the first supporter, and a receiving space formed by those supporters, the first supporter having a light aperture, the second supporter having an inner surface facing the receiving space. The lens group includes a first lens abutting against the inner surface of the second supporter, a second lens stacked on the first lens and abutting against the inner surface of the second supporter, a third lens stacked on the second lens and abutting against the inner surface of the second supporter, and a fourth lens stacked on the third lens and abutting against the inner surface of the second supporter, for ensuring the concentricity among the lenses and keeping the lens group coaxial with the lens barrel.

摘要： Disclosed is lens module. The lens module includes a barrel and a lens group disposed in the barrel. The lens group includes a first lens element connecting with the barrel and a second lens element connecting with the first lens element. The first lens element connecting with the barrel makes the lens module have a first matching precision. The first matching precision makes the barrel and the lens group be concentric. The first lens element has a first arc surface and the second lens element has a second arc surface engaging with the first arc surface which makes the lens module have a second matching precision. The second matching precision makes the first lens element and the second lens element be concentric.

摘要： The present invention discloses a pseudo-random bit sequence (PRBS) generator which outputs the entire datapath, or entire pseudo-random bit sequence, over one single clock cycle. This is accomplished by removing redundancy, or any redundant exclusive-or gates from linear feedback shift registers; using logic to identify the critical path and optimal shift for the critical path; and dividing the datapath into several pipeline stages to increase the clock rate (i.e., transmission speed).

摘要： The present disclosure discloses a lens module. The lens module includes a lens barrel and a lens group. The lens group is installed inside the lens barrel. The lens barrel includes a first barrel wall extended horizontally and a second barrel wall bended and extended from the first barrel wall. The lens module also includes a stop and a press ring. The stop is fixed on the first barrel wall. The press ring is located on the stop and presses on the stop. The stop and the lens group are lined up in turn from object side to image side. The length of the lens barrel is reduced due to the stop and the press ring, when shaping of lens barrel is being done, production difficulty of shaping is decreased, and the yield of qualified lens barrel is increased.

摘要： A lens module includes a lens supporter, and a lens group received by the lens supporter. The lens supporter includes an aperture plate, a main body extending downwardly from the aperture plate and a receiving space formed by the aperture plate and the main body, the aperture plate having a light aperture, the main body having an internal surface facing the receiving space. The lens group includes a first lens abutting against the aperture plate for forming a first alignment accuracy, a second lens stacked on the first lens and keeping a distance from the internal surface of the main body, a third lens stacked on the second lens and keeping a distance from the internal surface of the main body, and a fourth lens stacked on the third lens and abutting against the internal surface of the main body.
