According to one aspect, embodiments of the invention provide a power circuit comprising an input to receive input AC power from an AC source, an auxiliary charger configured to convert the input AC power from the input into DC power, a differential amplifier configured to be powered by the DC power from the auxiliary charger, to monitor the input AC voltage level of the input AC power, and to generate a sense signal based on a status of the input AC voltage level, and a processor coupled to the auxiliary charger and the differential amplifier, the processor configured to be coupled to an LPS, to be powered into a low power mode by the DC power from the auxiliary charger, and to analyze the sense signal from the differential amplifier in the low power mode of operation. According to one embodiment, the auxiliary charger is an offline DC-DC converter.

AC-OK detection circuit and method

A data transmission system includes a device and a base. The base includes a near field communication (NFC) module and a processing module configured to determine whether a wireless network exits. The NFC module includes a determining unit configured to determine whether the NFC module writes a predetermined tag after the processing module determines the wireless network exits and configured to determine whether the predetermined tag is an authorization code, a sending unit configured to send a service set identifier (SSID) and a password to the device after the predetermined tag is the authorization code, and a control unit configured to switch an input mode of the base to a wireless network mode after the SSID and the password are sent to the device. The device is configured to be connected to the wireless network after receiving the SSID and the password. A communication method is also provided.
