  • Publication number: 20250140377
    Abstract: The present application provides a nutrient pump control method, apparatus, device and storage medium. The method includes: obtaining a feeding scheme for a target object in response to a feeding instruction of the target object, wherein the feeding scheme comprises a plurality of feeding phases, and at least one feeding parameter is different in different feeding phases; and controlling the nutrient pump to output nutrients according to the feeding scheme. The method of the present application improves the accuracy and timeliness of the feeding via the nutrient infusion.

  • Publication number: 20250126341
    Abstract: A camera includes an image sensor package, a lens assembly, and an adhesive or dam compound. The image sensor package includes an image pixel array and support circuitry disposed around the image pixel array. The lens assembly includes a lens barrel disposed around lens elements configured to focus image light to the image pixel array. The adhesive or dam compound adheres the lens barrel to the support circuitry in an inactive area of the image sensor package.

  • Publication number: 20240298097
    Abstract: One example apparatus for providing a dual pixel array includes an array of pixels, each pixel comprising a plurality of photodiodes, each photodiode configured to generate a charge in response to incoming light and connected to at least one charge storage device. The plurality of photodiodes comprises one or more color photodiodes each including a chromatic filter, a color-select switch, and having at least one associated monochrome photodiode with a monochrome filter and a monochrome-select switch. The dual pixel array further comprises one or more analog-to-digital converters (“ADC”), each ADC connected to at least one of the charge storage devices of the photodiodes via the respective select switch, configured to selectively convert one or more stored voltages into a pixel value in response to a control signal. The color photodiodes and the monochrome photodiodes are arranged according to an arrangement.

  • Publication number: 20070139653
    Abstract: A method of generating surface plasmon resonance using excitation light directed at a thin metal film by a micromirror is described. A method that uses excitation light directed at a thin metal film by a micromirror scanner device is also described. A surface plasmon resonance imager is described comprising a micromirror that directs light to the surface of a thin metal film. Another method is described, comprising: a) directing light toward a thin metal film using a micromirror and b) detecting dynamic chemical events at or near the surface of the thin metal film. The dynamic events may be, for example, a fluidic change or a binding event.

  • Patent number: 5923466
    Abstract: The confocal imaging system and method involve the imaging of a specimen under observation by projecting a light pattern of illumination spots simultaneously on the specimen. This is accomplished by a pattern array unit which transforms light from a light source into a desired pattern of illumination spots, and reflects or rejects light outside the pattern. Light detected from the specimen is confined to a pattern conforming to the pattern of the illumination spots by the same pattern array unit which rejects light beyond the pattern, and rejected light from the pattern array unit is transmitted back to the light source. Image signals are created from the received light and stored, and the stored image signals are combined to form a complete image frame.

  • Patent number: 5363186
    Abstract: A five step method is used to produce an optical wave. The first step is to pick the desired far field pattern of the diffractive optical wave. The second step entails transforming the desired far field pattern to the desired source using a fast fourier transform (FFT). In the third step we use the formula exp[j.phi..sub.i (.sigma..sub.i)]=A.sub.i exp(j.phi..sub.i) to find the standard deviation .sigma..sub.i for each pixel i that produces the desired/average amplitude. Next, we use a pseudo-random number generator to select phases .phi..sub.i from distributions of standard deviation .sigma..sub.i for each pixel. Finally, we check the solution with the FFT and our analyses of performance.
