Abstract: The present invention discloses a power source transfer circuit for switching among a plurality of power sources to supply power to a load. The power source transfer circuit includes a first switch, a second switch and a bypass switch, wherein one of the plurality of power sources supplies power to the load via the first switch and the second switch, and wherein the bypass switch is connected in parallel to the second switch on a neutral line and is configured to control neutral overlapping duration during switching among the plurality of power sources. The power source transfer circuit including a bypass switch provided by the present disclosure can reduce the neutral overlapping duration to microseconds during power source transfer, so as to realize fast and reliable response.

Abstract: An RRC connection method and device, and a readable storage medium, and pertain to the field of communications technology. The method includes: in a case that a Relay UE is in RRC_IDLE or RRC_INACTIVE, determining, by the Relay UE, whether a first condition is satisfied; and triggering, by the Relay UE, an RRC connection establishment or RRC connection recovery procedure in a case that the Relay UE satisfies the first condition; where the first condition includes one or more of the following: the Relay UE determines to provide a relay service for one or more remote terminals Remote UEs; and the Relay UE receives one or more first messages from one or more Remote UEs, where each of the first messages carries a first cause value cause value of each of the Remote UEs for requesting RRC connection recovery or RRC connection establishment.

Abstract: A device for detecting a slot wedge, an air gap and a broken rotor bar is provided, where a sequential circuit generates double concurrent pulses; the sequential circuit is connected to driving power modules; the driving power modules are connected to front-end interface circuits; the front-end interface circuits convert the double concurrent pulses into corresponding magnetic-field pulses; the magnetic-field pulses are transmitted to power supply terminals on adjacent phases of stator windings through impedance matching pins and coupled at a corresponding coil, air gap and squirrel cage rotor to generate single groups of cyclic rotating magnetic potentials; single rotating magnetic potentials are sequentially generated in adjacent slots on each of the phases of the stator windings; rotating electric potentials in magnetic circuits with two symmetrical phases are magnetically coupled to form distributed coupling magnetic field reflected full-cycle waves for reflecting a difference of a corresponding slot wedg

Abstract: An in vitro analysis diagnostic instrument, and a microfluidic chip and method for sorting and enriching circulating tumor cells. The microfluidic chip includes a functional board. A first side face of the functional board is provided with a primary sorting channel in communication with a sample inlet and a fine screening channel in communication with the primary sorting channel, and a deepened channel is dug on the side of the fine screening channel away from the aggregation of circulating tumor cells. The deepened channel is arranged in an extension direction of the fine screening channel, and the deepened channel has a depth greater than that of the fine screening channel.
