  • Patent number: 12228823
    Abstract: A light emitting substrate is provided. The light emitting substrate includes at least one light emitting controlling unit. The at least one light emitting controlling unit includes a plurality of light emitting elements arranged in M rows and N columns and grouped into (P×Q) number of sub-units, M being an integer equal to or greater than one, N being an integer equal to or greater than one, P being an integer equal to or greater than one, and Q being an integer equal to or greater than one; P groups of first voltage signal lines; and Q groups of second voltage signal lines. The (P×Q) number of sub-units are arranged in P rows and Q columns. A respective sub-unit in a p-th row and a q-th column includes K columns of light emitting elements, K being an integer equal to or greater than one.

  • Publication number: 20230147085
    Abstract: A time-of-flight sensor includes an integrated circuit chip in which a voltage regulator and a load are disposed. The load includes a grouping of pixel circuits and modulation driver that is supplied power from the voltage regulator. The grouping of pixel circuits included in a pixel array disposed in the integrated circuit trip. Each one of the pixel circuits includes a photodiode configured to photogenerate charge in response to reflected modulated light, a floating diffusion configured to store a portion of charge photogenerated in the photodiode, and transfer transistor to transfer the portion of charge from the photodiode to the floating diffusion in response to a phase modulation signal generated by the modulation driver. A feedback circuit is coupled between the load and the voltage regulator and is coupled to receive a feedback signal from the feedback circuit in response to the load.

  • Patent number: 10298382
    Abstract: A frequency divider unit has a digital frequency divider configured to divide by an odd integer, and a dual-edge-triggered one-shot coupled to double frequency of an output of the digital frequency divider. The frequency divider unit is configurable to divide an input frequency by a configurable ratio selectable from at least non-integer ratios of 1.5, 2.5, and 3.5. In embodiments, the frequency divider unit relies on circuit delays to determine an output pulsewidth, and in other embodiments the output pulsewidth is determined from a clock signal. In embodiments, the unit is configurable to divide an input frequency by a configurable ratio selectable from at least non-integer ratios of 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, and 7.5 as well as many integer ratios including 2, 4, 6, and 8. In embodiments, the digital frequency divider is configurable to provide a 50% duty cycle to the one-shot.

  • Patent number: 7678776
    Abstract: The present invention relates to the inclusion complexes of butylphthalide, which is D, L-mixed or levorotatory, with cyclodextrin or cyclodextrin derivatives, to a process for their preparation and the use thereof. In the invention, the butylphthalide is complexed with cyclodextrin or cyclodextrin derivatives, preferably with hydroxypropyl-?-cyclodextrin in order to increase the water-solubility of butylphthalide, develop clinical solid or liquid formulations and improve the therapeutic effect of butylphthalide. The inclusion complex, in which the molar ratio of butylphthalide to cyclodextrin or cyclodextrin derivatives is in the range of 1:1-10, can be used to prepare infusion, injection, injectable powder, liquids for oral administration, syrup, tablets, granules, dispersible tablets and others.
