Abstract: The present invention discloses a liquid crystal lens and a manufacturing method thereof. At least one first electrode is disposed on a first substrate, a first alignment layer is disposed on the first electrode, a liquid crystal layer is disposed on the first alignment layer, a second alignment layer is disposed on the liquid crystal layer, an electric field uniformization layer is disposed on the second alignment layer, at least one second electrode and at least one third electrode are disposed on the electric field uniformization layer, and the second electrode is arranged around the third electrode. A second substrate is disposed on the second electrode and the third electrode. The third electrode which matches up with the second electrode produces an electric field gradient and the liquid crystal layer is affected uniformly by the electric field uniformization layer so as to achieve rapid focus purpose by the liquid crystal.

Abstract: This invention relates to a method and apparatus for image processing, and more particularly, this invention relates to a method and apparatus for processing image data generated by bioanalytical devices, such as DNA sequencers. An object of the present invention is to remove artifacts such as noise, blur, background, non-uniform illumination, lack of registration, and extract pixel signals back to DNA-beads in a way that de-mixes pixels that contain contributions from nearby beads.

Abstract: A timing device includes a timer and a flow meter mounted on the timer. The timer has a water inlet port and a water outlet port. The flow meter includes a first guide pipe mounted on the water outlet port and provided with a mounting chamber, a detector mounted on the first guide pipe, a rotation ring rotatably mounted in the mounting chamber, a magnetic member mounted on the rotation ring and movable to pass the detector, and a second guide pipe mounted on the first guide pipe. Thus, the water flow rate in the flow meter is calculated according to the times of the magnetic member passing the detector so that when the flow rate of the water passing through the flow meter reaches a preset value, the timer stops operating so as to control the water flow exactly.

Abstract: A shower head includes a nozzle unit, a quick connector mounted on the nozzle unit, and a bushing mounted in the quick connector. Thus, when the water flows through the shower head, the ambient air is introduced through the air conducting holes of the quick connector and the air conducting apertures of the bushing into the flow conduit of the bushing to break the vacuum state in the shower head and to perturb the water flow in the shower head so as to produce a turbulent flow in the shower head so that the water flow injected from the nozzle unit is divided into multiple straight water beams and multiple irregular water bubbles so as to increase the flushing angle and area of the shower head.
