  • Patent number: 11945744
    Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

  • Patent number: 10890733
    Abstract: The present disclosure describes image sensor modules that can include auto focus control. The modules also include features that can help reduce or eliminate tilt of the module's optical sub-assembly with respect to the plane of the image sensor. In some instances, the modules include features to facilitate highly precise positioning of the optical sub-assembly, and also can result in modules having a very small z height.

  • Patent number: 10714638
    Abstract: Optoelectronic modules, such as imaging cameras, proximity sensors, range cameras, structured-light/pattern generators, and image projectors, and methods for their manufacture, are disclosed. The optoelectronic modules exhibit particularly small dimensions. The optoelectronic modules include an optical assembly, an intermediate substrate, and a base substrate. The optical assembly includes a flange portion. An adhesive layer between the flange portion and the intermediate substrate, and an additional adhesive layer between the intermediate substrate and the base can be substantially non-transmissive to light and can resist dimensional changes dues to moisture absorption, for example.

  • Patent number: 10498943
    Abstract: Optoelectronic modules include overmolds that support an optical assembly and, in some case, protect wiring providing electrical connections between an image sensor and a printed circuit board (PCB) or other substrate. The disclosure also describes wafer-level fabrication methods for making the modules.

  • Patent number: 10475830
    Abstract: An optical module comprising: a plurality of active optoelectronic components each one mounted on a respective printed circuit board (PCB), wherein each active optoelectronic component is associated with a respective different optical channel; a plurality of optical assemblies, each one is substantially aligned over a different respective optical channel; and a spacer separating the active optoelectronic components and PCBs from the optical assemblies, wherein the optical assemblies are attached by adhesive directly to an optical assembly-side surface of the spacer. A first active optoelectronic component is separated, by the spacer, from a first optical assembly by a first distance and a second active optoelectronic component is separated, by the spacer, from a second optical assembly by a different second distance.
