Abstract: One embodiment provides a modular green roof tray, house plant growth media and horticulture growth media, and a tree protection mat for weed and moisture control made from recycled disposable diapers. The growth medium and tree protection mat contain superabsorbent materials from diaper that can absorb waters and greatly reduce irrigation so to provide a drought resistant feature. One embodiment also provides a manufacturing process to perform 100% recycling of disposed diapers.

Abstract: A method of removing fixed pattern noise, comprising: S01: performing a single-frame segmented exposure on a pixel array; S02: reading a of the pixel array, comprising: S021: performing a soft reset, so as to set the reset signal of the pixel unit to an intermediate voltage, and reading a differential reset signal; S022: performing a hard reset so as to set the reset signal of the pixel unit to a high voltage; S023: turning on a transmission MOS transistor to enable an exposure signal of to photodiode to transmitted to the floating diffusion area, and reading a differential pixel transmission signal; S03: subtracting the differential reset signal from the differential pixel transmission signal to obtain an exposure signal with fixed pattern noise removed. Another method is removing fixed pattern noise and an image sensor are further provided.

Abstract: A full-frame image sensor system comprises at least a pair of readout circuits, at least a pair of channel selection circuits, and at least a pair of interface circuits arranged symmetrically with respect to a pixel array; the readout circuits are electrically connected to two sides of the pixel array respectively; the channel selection circuit and the readout circuit on a same side of the pixel array are electrically connected to each other. The interface circuit and the channel selection circuit on a same side of the pixel array are electrically connected to each other. As a result, the circuits on the two sides of the pixel array are substantially symmetrical, the center of the pixel array coincides with the center of the entire chip.

Abstract: A system and method for regulating transfer characteristics of an integral analog-to-digital converter are provided. The system comprises a cascade N-stage integrator structure having N integrators, the input end of the first integrator is connected to a voltage, the output end of each integrator is connected to the input end of the adjacent integrator, and the output end of the Nth integrator is connected to an output node (VRAMP). Wherein, the N is positive integer greater than or equal to 2. In the cascade multistage integrator structure, the voltage of the output node (VRAMP) is in direct proportion relation with the time to the power of N. By adopting a cascade multistage integrator according to the present disclosure, it is simple to regulate transfer characteristics of the ADC, and the cascade digital signal processing is convenient, which can reduce the ADC conversion time and improve the ADC conversion rate.
