  • Publication number: 20240094527
    Abstract: A defog lens for vehicles includes a lens barrel, a lens, and a hydrophilic layer. The lens barrel has an opening toward an object side. The lens is disposed in the lens barrel and is located at the opening. The hydrophilic layer covers a surface of the lens and includes silicone compounds. Water droplets condensed on the lens could form a sheet film sticking to the surface of the lens and hard to form spherical water droplets, thereby improving the problem that the field of view of the conventional lens is blocked by spherical water droplets, effectively improving the clarity of the image captured by the defog lens, and therefore the defog lens could be applied to various environments.

  • Publication number: 20230020200
    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.
