Abstract: The video surveillance device with infrared LEDs has a casing and utilizes a partition element within the casing to place a camera assembly behind the partition element and the infrared LEDs in indentations on a front side of the partition element. A protective lens is interfaced directly with a washer on the front side of the partition element. As such, the light interference by the lens is effectively improved, while the external impact is buffered and absorbed largely by the washer, not directly on the camera assembly. In addition, the camera assembly is mounted on a downwardly concaved platform so that the camera assembly is able to slide along the curvature of the platform to aim at a specific direction. On the other hand, the LEDs are mounted on slant aluminum bases so that they could be aimed at different directions from that of the camera assembly.

Therefore, this invention has the advantages of high working efficiency, low energy-consumption, and is expected to produce minimum environmental pollution.

Abstract: Disclosed is a physiological approach of a penile venous stripping surgical procedure for patients with erectile dysfunction (ED), which mainly contains a revolutionary surgical solution of treating leakage veins for restoring erectile function based on a template of penile tunical and venous anatomy. The method entails a thorough penile venous stripping and then being ligated of one deep dorsal vein and a pair of cavernosal veins whereas two pairs of para-arterial veins are rendered for segmental ligation rather than being stripped closest to the tunica albuginea by using a set of specific instruments under an acupuncture-aided local anesthesia on an ambulatory basis. Although the techniques for handling venous tissues with stripping and then ligation is extraordinarily challenging, this innovative method turns the venous treatment for ED from one that has been abandoned to a curable option.

Abstract: Disclosed is a method for making a bicycle pedal, comprising the following steps: (A) cutting, in which an elongate metal plate is formed by pressing and two coupling holes are formed through the plate; (B) bending, in which the metal plate is bent to have the opposite ends jointed to each other, forming a circumferentially enclosed hollow pedal frame with the two coupling holes concentrically located and spaced from and opposing each other; and (C) welding, in which a collar is mounted outside the pedal frame concentric with respect to each of the coupling holes through welding to provide a sufficient contact area for rotatably receiving and supporting a spindle therein, whereby the pedal frame is rotatable about the spindle for pedaling operation of a bicycle. This method overcomes the various drawbacks occurring in metal-cast or plastic injection-molded bicycle pedals, providing economic advantages for high-mix low-volume productions.
