Abstract: Techniques for establishing connections between user devices and headless devices attempting to connect to networks. A headless device may attempt to connect to an access point that requires interaction with a captive portal webpage for access to a network. However, the headless device my lack a display to present the captive portal webpage. The headless device may establish a connection with a user device using a PAN protocol. The headless device may then receive the captive portal webpage received from the access point, and relay the webpage to the user device using the PAN protocol. A user may use the user device to interact with the captive portal webpage, and the user device may then relay interaction data back to the headless device using the PAN protocol. The headless device may then provide that interaction data to the access point to be provided access to the network.

Abstract: A modular AC/DC power conversion module for power sources and loads and a method of driving the same is provided. When an AC/DC converter is electrically coupled to an external power source, a microprocessor is electrically energized by a buck auxiliary circuit, under control of the microprocessor, a DC/DC converter is activated for a certain time period, and then, the AC/DC converter is activated. Thereafter, an output voltage of the AC/DC converter is boosted, and an output voltage of the DC/DC converter is boosted accordingly. Power elements in the downstream side DC/DC converter are activated first, and then power elements in the upstream side AC/DC converter are activated, thereby an inrush current is suppressed. Once the external power source is connected, the buck auxiliary circuit will automatically reduce a voltage of the power input to activate the module. It realizes that the module will autonomously operate after being electrically energized.
