  • Patent number: 12394995
    Abstract: The disclosure provides an Internet of things device and a battery power supply circuit thereof. A voltage of a battery is compared with a predetermined over-discharge voltage to generate a comparison signal. A battery protection circuit serves as a power supply path from the battery to a load and determines whether to cut off the power supply path according to the comparison signal. The battery protection circuit cuts off the power supply path when the voltage of the battery decreases from a value greater than the predetermined over-discharge voltage to a value less than the predetermined over-discharge voltage, but does not turn on the power supply path when the voltage of the battery increases from a value less than the predetermined over-discharge voltage to a value greater than the predetermined over-discharge voltage.

  • Patent number: 12046127
    Abstract: A video doorbell and an automatic setting method thereof are provided. The video doorbell includes a bridge rectifying unit, a switch unit, and a processing unit. The bridge rectifying unit is configured to output a DC voltage when receiving an AC power from a transformer. During a chime type detection mode, the switch unit is configured to switch a path of the AC power for generating a short-circuit current to trigger a chime. After the short-circuit current is kept for a detection time, the short-circuit current is terminated. During the chime type detection mode, when the short-circuit current is terminated, the processing unit detects a rising time of the DC voltage rising from a first level to a second level, and determine whether the chime is an analog chime or a digital chime according to the rising time.
