Abstract: An intraocular pressure inspection device includes an intraocular pressure detection unit, a high-precision positioning system and a wide-area positioning system, wherein according to the position of the intraocular pressure detection unit, a set of high-precision coordinates output by the high-precision positioning system and a set of wide-area coordinates output by the wide-area positioning system are integrated in appropriate weights to obtain a set of more precise integrated coordinate. The above-mentioned intraocular pressure inspection device can prevent the intraocular pressure detection unit from failing to operate once it is not in the working area of the high-precision positioning system.

Abstract: An auxiliary operation device for a droplet dispenser includes a droplet sensor, an imaging device and a processor. The droplet sensor has a detected area located between a droplet dispenser and a target area, wherein the droplet sensor detects a droplet output from the droplet dispenser, and outputs a corresponding droplet detection signal. The imaging device captures an image of the target area. The processor obtains a dripping time point at which the droplet passes through the detected area according to the droplet detection signal, and determines whether the target area is shielded within a first time range according to the image, so as to evaluate whether the droplet has successfully dropped into the target area. The above-mentioned auxiliary operating device of the droplet dispenser can objectively determine whether the droplets successfully drops into the target area, and improve the accuracy of judgment.

Abstract: An overflow valve cover includes a planar surface having a first surface and an opposing second surface. The planar surface includes a plurality of openings spaced apart along on the planar surface. An angled slat is positioned within each of the plurality of openings. A top edge of a collar is affixed to the circumference of the planar surface. A connector is positioned on the inner surface of the planar surface and extending away from the second surface.

Abstract: A positioning structure for assembly of the water faucet plaquette has a plaquette having front face, a depressed back and a through-hole. The depressed back of the plaquette has a bent positioning claw. A wall permanent seat has a plaquette assembly surface, an abutting surface and a fixed portion. The fixed portion is positioned fixedly onto the wall. The plaquette assembly surface of the wall permanent seat is fitted with limit surfaces, which are aligned transversely with the positioning claw. A soft liner ring is fitted with at least two slots that are fitted onto the positioning claws. The limit surface has a pair of tabs and a vertical lug engaged with the position claw.
