  • Optical communication interface system
    Patent number: 11750294
    Abstract: Systems and methods for optical communication are provided. For instance, a method for optical communication can include receiving, by a first coupling module, a power-on signal from a first electronic device coupled to the first coupling module. The method can also include relaying, by the first coupling module, a first optical signal to a second coupling module coupled to a second electronic device. The method can also include relaying, by the second coupling module, in response to receipt of the first optical signal, a second optical signal to the first coupling module. The method can also include activating, by the first coupling module, in response to receipt of the second optical signal, a data transfer circuit for relaying data via an optical communication interface between the first coupling module and the second coupling module.

  • Power switching apparatus
    Patent number: 11038491
    Abstract: In a power switching apparatus, a first switch includes a first end coupled to a first input terminal, a second end coupled to an output terminal, and a control end coupled to a second input terminal and coupled to a ground via a first resistor. A second resistor is coupled between the output terminal and the ground. A second switch includes a first end coupled to the second input terminal, a second end coupled to the output terminal and a control end coupled to the ground via a third resistor. A third switch includes a first end coupled to the control end of the second switch and the first end of the third resistor, a second end coupled to the first input terminal and a control end coupled to the second input terminal and coupled to the ground via the first resistor.
