Abstract: An optical module including a light source and an optical sensor is provided. The optical sensor includes a pixel matrix and an opaque layer. The pixel matrix includes a plurality of unblocked pixels, a plurality of first pixels and a plurality of second pixels. The opaque layer covers upon a first region, which is a part of each first pixel, and upon a second region, which is a part of each second pixel, but does not cover upon the unblocked pixels, wherein the first region and the second region are symmetrically arranged in a first direction, and uncovered regions of the first pixels and the second pixels are arranged to be larger at a pixel edge than at a pixel center.

Abstract: A touch sensor, a touch pad, a method for identifying an inadvertent touch event and a computer device are provided. A control circuit of the touch sensor identifies whether there is the inadvertent touch event in response to the touch signals that indicates at least one touch event applied to the touch pad having the touch sensor. In the method, the touch signals are discarded if the inadvertent touch event is identified when a touch position corresponding to the touch signals is within an object detection area defined for the touch pad, or the touch positions in response to the touch signals are reported to the computer device if a multi-touch event is identified when the touch positions are within a touch detection area defined for the touch pad.

Abstract: A sprayer includes: a container; a passage including a transparent window, a first opening, a second opening and a resonator, wherein when liquid in the container is passed through the resonator via the first opening, the liquid is emitted as a gas via the second opening; and a removable detection unit disposed outside of the passage. The removable detection unit includes: a light source for illuminating the gas in the passage; an optical sensor disposed to detect a parameter of light reflected by the gas; and a processor coupled to the optical sensor for stopping the resonator from generating the gas when the parameter is below a threshold. The passage further includes a cavity disposed on a bottom surface of the passage in front of the optical sensor, wherein when the gas in the passage contacts the bottom surface, resultant water vapour will enter the cavity.

Abstract: There is provided a barcode detection device including an image sensor and a processor. The image sensor captures an image frame of a color barcode. The processor sequentially processes every row of the image frame to find at least one color segment in each row of the image frame, categorizes color segments of a same color in one cluster according to a position relationship and a color similarity of the color segments in the image frame, and averages color parameters of pixels in one cluster to accordingly recognize a color of the pixels in said one cluster.
