  • Publication number: 20150002658
    Abstract: A liquid level measuring device includes a container and a digital electronic device. The container is located at a detection region. The container has an opening, so that a liquid is permitted to flow into the container through the opening. The digital electronic device is combined with the container. The digital electronic device includes a lens, and an optical axis of the lens is directed to and perpendicular to a detection plane. A light source illuminates the detection plane. The lens is operated in a fixed-focus mode to shoot the detection plane to acquire an image stream. Each image frame of the image stream contains a corresponding liquid surface image. After an image analyzing operation is performed on the corresponding liquid surface image to calculate the corresponding liquid surface image, a liquid level of the liquid is realized.

  • Patent number: 8891178
    Abstract: This invention provides an optical lens system in order from an object side to an image side comprising: a first lens element having a convex object-side surface; a negative second lens element having a concave object-side surface and a convex image-side surface; a positive third lens element having a convex object-side surface and a convex image-side surface; a plastic negative fourth lens element having a concave object-side surface and a convex image-side surface, with both the object-side and image-side surfaces thereof being aspheric. By such arrangement, the incident angle of off-axis light projected onto the sensor can be suppressed for improving the sensitivity of the sensor effectively. Also, a sufficient back focal length can be retained for disposing other optical elements (e.g., an IR-pass filter), and thereby the system can be more suitable for the infrared aspect of optical imaging systems.
