Abstract: Various embodiments of the present disclosure are directed towards a camera module comprising flat lenses. Flat lenses have reduced thicknesses compared to other types of lenses, whereby the camera module may have a small size and camera bumps may be omitted or reduced in size on cell phones and the like incorporating the camera module. The flat lenses are configured to focus visible light into a beam of white light, split the beam into sub-beams of red, green, and blue light, and guide the sub-beams respectively to separate image sensors for red, green, and blue light. The image sensors generate images for corresponding colors and the images are combined into a full-color image. Optically splitting the beam into the sub-beams and using separate image sensors for the sub-beams allows color filters to be omitted and smaller pixel sensors. This, in turn, allows higher quality imaging.

Abstract: The mutually supporting hydropower systems includes a first hydropower system, a second hydropower system, and a third hydropower system. Each hydropower system includes a hydropower unit, a number of waterwheels, a number of hoist devices, and a number of motors respectively connected to the hoist devices. Each waterwheel engages a hoist device. The motors are electrically connected to a hydropower unit. The waterwheels and the hoist devices are driven by the impact of seawater which is also used by each hydropower unit to produce electricity. 40% of the power from the first hydropower system is used to drive its motors. 30% of the power from the second and third hydropower systems are also used to drive the motors of the first hydropower system. The motors are therefore sufficiently powered to discharge seawater.

Abstract: The power generation device includes a fourth tube having an input end below sea level, a third hydro power module having an input end connected to an output end of the fourth tube, a fifth tube having an input end connected to an output end of the third hydro power module, an output end disposed above ground to expel seawater, and a number of step sections connected in between, and a number of flow guiding modules including first waterwheels, second waterwheels, hoist devices, motors, and transmission elements. The first waterwheels are configured along the fourth tube, the second waterwheels and the hoist devices are configured along the step sections, the motors are electrically connected to an external power source, and are connected to the hoist devices. The third hydro power module produces electricity as seawater flow through to power an external equipment or to be stored in a battery.

Abstract: A method for manufacturing food container includes the following steps: the husks of rice, oat, corn, soya bean, wheat or the mixture thereof are used as raw material to make food containers; an eatable adhesive is added in order to bind the husks; the bound husks is rolled into a sheet; after sterilizing the sheet with UV light; the sheet is shaped into a container of a desired shape, such as a bowl or a tray; a water-resistant is coated on the surface of the container.
