A cigarette device includes a housing, and a loading cavity, an airflow sensor, a circuit control unit, and a power supply are disposed in the housing. A fluid channel is located between the loading cavity and the housing, and the fluid channel is in communication with the outside of the housing and the inside of the loading cavity. An electromagnetic induction heating element surrounds the outside of the loading cavity; and the electromagnetic induction heating element is electrically connected to the power supply, and the circuit control unit is electrically connected to the airflow sensor and the electromagnetic induction heating element. When the cigarette device is used in combination with a cigarette added with a magnetic material, the cigarette can be heated uniformly and generate vapor quickly, to ensure a consistent vaping taste and improve utilization of tobacco while achieving immediate vaping and immediate stopping, which helps improve user experience.

Cigarette device

A converter system includes a switch adapted to be coupled to an inductor, and configured to switch between first and second states responsive to a loop control signal. Calibration circuitry is configured to operate in first and second control modes, provide a calibration voltage in the first control mode, and store the calibration voltage in the second control mode. In a first instance of the first control mode, the calibration voltage is based on a difference between a feedback voltage and a reference voltage. In a second instance of the first control mode, the calibration voltage is the stored calibration voltage from the second control mode. A comparator is coupled to the switch and the calibration unit, and is configured to provide the loop control signal based on a combination of at least the feedback voltage, the reference voltage, the calibration voltage, and a periodic signal.

Voltage converter with loop control

A voltage converter system includes a switch configured to operate in first and second states. Compensation circuitry is configured to provide: a certain reference voltage as a reference voltage when the switch has the second state; and a compensated reference voltage as the reference voltage when the switch has the first state. Control circuitry is configured to switch the switch between the first and second states based on the reference voltage and a feedback voltage generated based on an output voltage of the voltage converter system.

The disclosure provides an optical network system, an Optical Line Terminal (OLT), an Optical Network Unit (ONU) and an Optical Distribution Network (ODN) apparatus. The system includes: an OLT configured to modulate and encode at least one line of time-division-multiplexed downlink signals, synthesize the downlink signals encoded into one line and then output it, receive uplink signals, and decode the uplink signals received and then output them; an ODN configured to separate the downlink signals received into multiple lines and then output them, synthesize the uplink signals received into one line, and then output it to the OLT; and ONUs configured to receive the downlink signals output from the ODN, decode the downlink signals received and output them, encode one line of time-division-multiplexed uplink signals, and output the uplink signals encoded to the ODN. Decoding of the downlink signals and encoding of the uplink signals can further be implemented by the ODN. By means of the solution of the disclosure, a hybrid Passive Optical Network (PON) system based on a Time Division Multiplexing (TDM) technology and an Optical Code Division Multiple Access (OCDMA) technology.
