    • A charging circuit and method for charging a power storage device in a power over Ethernet environment are necessary to prevent unnecessary power consumption. Power sourcing equipment continuously supplies power to a connected device after determining that the device is compatible. In order to prevent supply of power after a power storage device attains full charge, a charging circuit may include an interface for supplying electric power; a sensing circuit including a switch in series with a resistor; and a voltage detection circuit. The voltage detection circuit may communicate with the sensing circuit and may output a first signal that turns the switch OFF when the voltage of the power storage device is greater than or equal to a first voltage and may output a second signal that turns the switch ON when the voltage of the power storage device is less than or equal to a second voltage.

    • In a method and module for controlling rotation of a motorized spindle driven by a driving unit, a sensing unit senses vibration of the spindle and generates a voltage signal corresponding to the vibration of the spindle. A processing unit receives the voltage signal from the sensing unit, generates an adjusting ratio equal to a reference voltage corresponding to a predetermined vibration level of the spindle by the voltage signal upon detecting that the voltage signal is greater than the reference voltage and is less than a predetermined threshold voltage that is greater than the reference voltage, and outputs a control signal corresponding to the adjusting ratio to the driving unit such that the driving unit reduces a rotation speed of the spindle by the adjusting ratio in response to the control signal from the processing unit.

    • A disposable material layer is first deposited on a graphene layer or a carbon nanotube (CNT). The disposable material layer includes a material that is less inert than graphene or CNT so that a contiguous dielectric material layer can be deposited at a target dielectric thickness without pinholes therein. A gate stack is formed by patterning the contiguous dielectric material layer and a gate conductor layer deposited thereupon. The disposable material layer shields and protects the graphene layer or the CNT during formation of the gate stack. The disposable material layer is then removed by a selective etch, releasing a free-standing gate structure. The free-standing gate structure is collapsed onto the graphene layer or the CNT below at the end of the selective etch so that the bottom surface of the contiguous dielectric material layer contacts an upper surface of the graphene layer or the CNT.
