  • Patent number: 11948497
    Abstract: A display device includes a plurality of sub-pixels. The sub-pixels include a first sub-pixel and a second sub-pixel. The first sub-pixel includes a first light emitting element and a first control circuit. The first control circuit is configured to provide a first driving current to the first light emitting element. The second sub-pixel includes a second light emitting element and a second control circuit. The second control circuit is configured to provide a second driving current to the second light emitting element. The first control circuit and the second control circuit are configured to differently control pulse amplitude of the first driving current and pulse amplitude of the second driving current, such that both of the first light emitting element and the second light emitting element emit at a target wavelength or a color point range (e.g. +/?1.5˜2 nm).

  • Patent number: 11937932
    Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

  • Patent number: 11863071
    Abstract: A power converter having a smooth transition control mechanism is provided. An oscillator circuit outputs a clock signal. A control circuit receives the clock signal from the oscillator circuit and outputs a control signal based on the clock signal. A driver circuit outputs a high-side conduction signal and a low-side conduction signal according to the control signal. A high-side switch is turned on or off according to the high-side conduction signal from the driver circuit. A low-side switch is turned on or off according to the low-side conduction signal from the driver circuit. The oscillator circuit receives the high-side conduction signal from the driver circuit. The oscillator circuit, according to the high-side conduction signal, determines whether or not the clock signal outputted to the control circuit needs to be adjusted.

  • Patent number: 11349325
    Abstract: A pulse controlled charging method for higher temperature charging in addition to the current-reducing operation at ambient temperature. A specific software control strategy for these purposes is proposed, which can be divided into two parts, (a) two-stage charging current control at ambient temperature, which sets different current-limiting transient points for chargers with different outputs; (b) high-temperature pulse charging, which utilizes an internal NTC (Negative temperature coefficient) thermistor inside the charger to detect the internal temperature of the charger, if the temperature exceeds a pre-determined value, the charging process will be stopped for a period of time to avoid the temperature of the charger becoming too high.

  • Publication number: 20220092332
    Abstract: Systems, methods, and non-transitory computer-readable media can provide at least one frame of a content item to a saliency prediction model, the saliency prediction model being trained to identify salient points of interest that appear in content items. Information describing at least a first salient point of interest that appears in the at least one frame can be obtained from the saliency prediction model. The first salient point of interest can be predicted to be of interest to users accessing the content item. A view-based projection can be applied to a region corresponding to the first salient point of interest, wherein the view-based projection enhances a quality in which the region is presented.
