Abstract: A charge pump voltage regulator circuit is provided. The charge pump voltage regulator circuit includes: an oscillating frequency source circuit for providing multiple oscillating frequencies; a Mux circuit for receiving the oscillating frequencies and a control signal, selecting one of the oscillating frequencies as a driving clock frequency based on a value of the control signal and outputting the driving clock frequency, wherein each oscillating frequency corresponds to a corresponding value of the control signal; a charge pump for raising an input voltage to a value corresponding to the driving clock frequency and outputting a voltage; a voltage divider circuit for dividing the voltage output from the charge pump to obtain multiple divided voltages; and a comparator circuit for comparing each divided voltage with a reference voltage to obtain multiple comparison values, which are taken as the control signal for the Mux circuit.

Abstract: An anti-fog glass includes a glass body configured as a single layer or a multilayer stack; an active anti-fog layer disposed on the glass body and heating up when being provided with power; and a passive anti-fog layer disposed on the glass body and inhibiting fog from forming on the passive anti-fog layer. The passive anti-fog layer is a super hydrophobic coating and/or hydrophilic coating. Both the active anti-fog layer and the passive anti-fog layer are simultaneously disposed on the glass body to inhibit fog from forming. In this way, in a region of the glass body not covered by the active anti-fog layer, the anti-fog function is achieved by the passive anti-fog layer to a certain degree; in addition, in a region where the passive anti-fog layer itself cannot provide a desired anti-fog level, the active anti-fog layer together with the passive anti-fog layer provide a better anti-fog effect.

Abstract: A device for preventing cables against external damage based on sound source localization comprises a power supply unit, and a sound source sensor unit, a camera unit, a signal processing unit and a wireless communication unit which are electrically connected to the power supply unit. The signal processing unit is connected to the sound source sensor unit, the camera unit and the wireless communication unit. The camera unit is associated with the sound source sensor unit. When the sound source sensor unit recognizes a target signal, the signal processing unit sends a trigger signal to the camera unit, and then the camera unit is triggered to replay a surveillance video to determine whether or not a target really exists. Compared with the prior art, the device has the advantages of being good in safety, high in reliability and the like.
