  • Publication number: 20250024179
    Abstract: An image sensing device and an image sensing method are provided. The image sensing device includes a pixel array, first row-selecting lines, second row-selecting lines and a control circuit. Pixels in the pixel array are arranged to form a plurality of rows and a plurality of columns. A first set of the pixels of each row is electrically connected to the corresponding first row-selecting line, and a second set of the pixels of each row is electrically connected to the corresponding second row-selecting line. The control circuit performs an HFR readout process to obtain an image frame. The rows are divided into a selectable portion and an unselectable portion. In each of HFR readout periods, the first set of an unselected first row and the second set of an unselected second row are selected from the selectable portion of the rows.

  • Publication number: 20230049005
    Abstract: The present invention concerns a method of treating peanut allergy in a subject, or a population of subjects, the method comprising administering to said subject or population of subjects a peanut allergen by an oral immunotherapy (OIT) regimen comprising a dose escalation phase in which the peanut allergen is administered in a dose which is increased in increments from an initial dose of the allergen equivalent of 5 mg peanut protein or less to a dose of the allergen equivalent of 200 mg peanut protein or more within 4 to 9 weeks from the administration of the initial dose. The treatment reduces the length of the build-up phase in peanut OIT methods and improves the likelihood or odds of the subject achieving sustained unresponsiveness.

  • Patent number: 11355054
    Abstract: The LED display system includes an array of LEDs and a driver circuit. The driver circuit has a PWM engine, an adder, an accumulator, a multiplier, and a frame butter. The multiplier multiplies an image data of a first bit depth (PWM) with a multiple (M) to produce an input data (PWM_M) having a second bit depth. The multiple has an integer section (MI) of one or more bit in length and a fraction section (MF) of one or more bit in length. The input data has an integer section (PWM_MI) and a fraction section (PWM_MF). The adder adds a value of PWM_MF of a current input data with a value of a remainder in an accumulator. The PWM engine receives PWM data from the frame buffer and generates PWM pulses to drive the LED array.
