  • Patent number: 10871694
    Abstract: A bistable cholesteric liquid crystal switchable window has two stable states in the absence of an applied voltage. A first stable state is a planar state which is transparent or reflective for visible light. A second stable state is a focal conic state which is opaque for visible light. The window can be switched from the first stable state to the second stable state via a first voltage pulse and from the second stable state to the first stable state via a second voltage pulse. The first voltage pulse and the second voltage pulse may have the same frequency.

  • Patent number: 10642334
    Abstract: A computer device includes a microprocessor, a voltage converter circuit converting a first voltage of a system power into a second voltage, a control circuit controlling supply of the second voltage and a detection circuit detecting whether power abnormality at the peripheral device has occurred. When confirming that the system power is being supplied normally, the microprocessor generates a first enable signal to enable the voltage converter circuit. When confirming that the voltage converter circuit functions normally, the microprocessor generates a second enable signal to enable the detection circuit. The detection circuit generates a first detection signal according to detection result for the microprocessor to determine whether to supply the second voltage to the peripheral device. When the first detection signal indicates that power abnormality has not occurred, the microprocessor generates a third enable signal to enable the control circuit to supply the second voltage to the peripheral device.
