Abstract:
A power system includes a power conversion circuit, a DC converter and an inverter. The power conversion circuit is coupled to a AC supply line and a DC supply line to convert voltage between the AC supply line and the DC supply line. The DC converter is coupled to the DC supply line and a charging device. The inverter is coupled to the AC supply line and the charging device. When the charging device provides a supply power to the inverter, the inverter is configured to convert the supply power into a recovered power and transmit the recovered power to the power conversion circuit.
Abstract:
A gas exhaust control method applied to a respiratory assistance apparatus includes the following steps of: applying gas to a face mask of the respiratory assistance apparatus; detecting a pressure in the face mask; when the pressure in the face mask is lower than a preset pressure range, shrinking a perforation size of an exhaust structure of the face mask by a driving unit of the respiratory assistance apparatus; and when the pressure in the face mask is higher than the preset pressure range, expanding the perforation size of the exhaust structure of the face mask by the driving unit. A respiratory assistance apparatus applied with the gas exhaust control method is also disclosed.
Abstract:
A self-diagnosing system including a communication diagnosing model, a device communication-status identification model, a communication-line identification model, and a graphic updating model is disclosed. The communication diagnosing model determines whether device data of each peripheral device is received. The device communication-status identification model identifies the communication-line of the peripheral device to be normal when the device data is received and determines whether a connection status of the peripheral device is a first category or a second category based on a target data. The communication-line identification model identifies the peripheral device to be offline when the device data is not received and inspects the communication-line of the peripheral device to determine whether the connection status of the peripheral device is the second category or a third category. The graphic updating model updates a displaying icon of each peripheral device based on the connection status of each peripheral device.
