摘要： A hot swappable device includes a port, a firmware module, and an interrupt masking module. The port includes a Peripheral Component Interface express Physical Layer, and the Peripheral Component Interface express Physical Layer includes multiple lanes lanes. The Peripheral Component Interface express Physical Layer detects an analog signal in each of the multiple lanes, when it is detected that an amplitude of an analog signal in one of the multiple lanes is less than a preset threshold, generates an ALOS signal corresponding to the lane, and transmits the ALOS signal to the interrupt masking module. The interrupt masking module generates an ALOS interrupt signal corresponding to the lane and sends the ALOS interrupt signal to the firmware module. If the firmware module receives, in a preset time period, an ALOS interrupt signal corresponding to each lane, the firmware module resets the port.

摘要： A wireless charging device is disclosed, which includes: a charging pad and a first controller. The charging pad includes a plurality of charging units, the plurality of charging units include a first charging unit and a second charging unit. When a first electromagnetic coupling strength between the first charging unit and the to-be-charged device is greater than or equal to a first threshold, the first controller is configured to control the first charging unit to separately charge the to-be-charged device. When both the second electromagnetic coupling strength between the second charging unit and the to-be-charged device and the first electromagnetic coupling strength are less than a first threshold, and are greater than or equal to a second threshold, the first controller is configured to control the first charging unit and the second charging unit to jointly charge the target to-be-charged device.
