A scene switching method includes: determining whether a user moves from a first scene to a second scene or not; if yes, acquiring voiceprint information of the user in the second scene; determining each device to be switched in the first scene according to the voiceprint information, and obtaining an operation state of the device to be switched; and determining an operation state of each target device in the second scene.

Scene switching

An earbud assembly includes a charging case and at least one wireless earbud suitable to be stowed in the charging case. The charging case includes a battery, a charger electrically connected to the battery, a sensor configured to detect the opening and closing operations of the charging case, a battery status indicator that has a first state when the battery of the charging case is in a normal working condition and a second state when the battery of the charging case is exhausted. The earbud includes a processor and a status detector for detecting the state of the battery status indicator when the earbud is stowed in the charging case. The processor of the earbud is configured to power off the earbud when the status detector detects that the battery status indicator is in the second state.

Wireless earbud assembly

Provided is a micro- and nano-fluidic chip, including at least one nanochannel array layer and at least one microchannel array layer that are alternately stacked. The at least one nanochannel array layer includes nanochannels, the at least one microchannel array layer includes input units and/or output units. The input unit includes inlet microchannel arrays and inlets, and the output unit includes outlet microchannel arrays and outlets. The inlet microchannel array includes inlet microchannels, the outlet microchannel array includes outlet microchannels, and the inlet microchannels and the outlet microchannels are connected through the nanochannels.

A dual active bridge circuit includes a primary side circuit including first high-side transistor and a first low-side transistor electrically coupled at a first node, and an energy transfer inductor coupled to the first node and configured to provide an inductor current based on a voltage differential across the energy transfer inductor. A secondary side circuit includes a second high-side transistor and a second low-side transistor electrically coupled at a second node. A transformer is configured to transfer energy from the primary side circuit to the secondary side circuit based on the inductor current. A controller is configured to drive each of the transistors between respective switching states with a same duty cycle to control the voltage differential across the energy transfer inductor. The same duty cycle is less than 50% such that all of the transistors are simultaneously off for a predetermined interval.
