  • Publication number: 20240139262
    Abstract: The present disclosure relates to a complex probiotic composition and a method for improving exercise performance of a subject with low intrinsic aerobic exercise capacity. The complex probiotic composition, which includes Lactobacillus rhamnosus GKLC1, Bifidobacterium lactis GKK24 and Clostridium butyricum GKB7, administered to the subject with the low intrinsic aerobic exercise capacity in a continuation period, can effectively reduce serum lactic acid and serum urea nitrogen after aerobic exercise, reduce proportion of offal fat and/or increase liver and muscle glycogen contents, thereby being as an effective ingredient for preparation of various compositions.

  • Patent number: 11258360
    Abstract: A switched-capacitor power converting apparatus and an operating method thereof are disclosed. The switched-capacitor power converting apparatus includes an output stage, a determination circuit, a switch control circuit and a voltage regulation circuit. The output stage has an output terminal. The determination circuit is coupled to the output terminal, and generates a mode switching signal according to an output voltage of the output terminal and a reference voltage. The switch control circuit is coupled to the output stage and the determination circuit and controls the output stage to operate in a default voltage mode or an operation mode according to the mode switching signal. The voltage regulation circuit is coupled to the output terminal and the determination circuit and maintains the output voltage of the output terminal at a default value in the default voltage mode.

  • Patent number: 10601321
    Abstract: A DC-DC converting controller, coupled to an output stage including a phase node and an operation switch coupled between the phase node and a ground voltage, includes a pulse-width modulation (PWM) unit, a zero-level comparator and a threshold voltage generation unit. The PWM unit, coupled to the output stage, provides the PWM signal to the output stage for controlling the operation switch. The zero-level comparator has a first input terminal, a second input terminal and an output terminal. The first input terminal is coupled to the phase node. The output terminal, coupled to the PWM unit, provides a zero-current voltage to adjust the PWM signal. The threshold voltage generation unit, coupled to the phase node and zero-level comparator, provides the threshold voltage to the second input terminal. The threshold voltage generation unit dynamically adjusts threshold voltage according to a default voltage and the phase voltage on the phase node.

  • Patent number: 5969278
    Abstract: A beverage cup includes a cup body, a base located on the cup body and having a circuit board and a speaker, and a cap closing on the base. The cap has a short straw portion protruding out and connected to an upper connect post aligned with a lower connect post in the base and connected to a long tube in the cup body. The circuit board is connected to two lead wires extending into the upper connect post and having their ends that are spaced apart a little in the passageway of the upper connect post. The two ends are connected electrically and power the circuit board to operate the speaker to when drink in the cup body is sucked out through the short straw portion.
