  • Publication number: 20220089325
    Abstract: A modularized large-sized carrier includes at least two body modules, at least one hermetic seal component and a back board. The body modules are connected to each other peripherally and arranged in a depth direction. The hermetic seal component surrounds junctions of the body modules. The back board is disposed behind the last one of the body modules. The modularized large-sized carrier overcomes existing carrier size limitations otherwise caused by injection molding machines and continuously expands in the depth direction to thereby enlarge the airtight storage space of the carrier.

  • Publication number: 20210173053
    Abstract: A distance measuring device includes a pulsed laser source, a light receiving unit and a computing module. The pulsed laser source emits a laser pulse to a target in accordance with a predetermined period. The light receiving unit has a photon receiving type of light receiving element that receives incident light and outputs a binary pulse, and the binary pulse is used to indicate whether a photon receiving event occurs. The computing module is configured to receive the binary pulse and determine whether an inter-period coincidence event occurs, and the inter-period coincidence event is defined by detecting a plurality of photon receiving events exceeding a predetermined count, on relative positions in a predetermined period number of the predetermined periods. If the calculation module determines that the inter-period coincidence event occurs, a distance of the target is calculated according to time information related to the inter-period coincidence event.
