摘要： Disclosed in the present invention are a balanced radio frequency power amplifier, a chip and a communication terminal. The radio frequency power amplifier divides, by means of a 90-degree power splitter unit, a radio frequency input signal into two equal-amplitude signals having a phase difference of 90 degrees, the two radio frequency input signals are amplified and then inputted into an adjustable 90 -degree power combiner, and the values of a adjustable capacitor and an adjustable resistor in the adjustable 90-degree power combiner are controlled by means of a control unit, so as to synthesize the two radio frequency input signals into one radio frequency input signal when the phase difference and amplitude difference of the two signals at different frequencies are the smallest, and to input the radio frequency input signal into a circuit of the next stage by means of a specific radio frequency transmission path.

摘要： Systems and methods obtain functional connectivity data in the whole brain to detect and predict brain disorders. This whole brain data is regionalized and then manipulated to derive functional connectivity data sets that can be used to show measured functional connectivity changes. This whole brain data may also be analyzed to determine changes in functional activity in both increased and decreased neural network connectivity. By identifying and then quantifying the functional connectivity differences between healthy and diseased subjects, a classification for individual subjects can be made.

摘要： A solid-state circuit breaker and breaking method are disclosed. In an embodiment, the solid-state circuit breaker includes a semiconductor switch; a controller, connected to the semiconductor switch; and an energy absorber, connected in parallel with the semiconductor switch. The controller is configured to obtain an equivalent inductance of a circuit of the solid-state circuit breaker upon a fault occurring in a line. Further, upon the equivalent inductance being greater than an inductance estimated value, the controller is configured to set a second current fault threshold. Finally, upon a fault current of the line reaching the second current fault threshold, the semiconductor switch is controlled to execute a closing operation.

摘要： Techniques for real-time virtual sensing of an axle assembly temperature include determining, at a controller of a vehicle, an initial temperature of an axle assembly of the vehicle based on an ambient temperature and a fluid temperature of a transmission. The techniques include determining, at the controller, an operating mode of the vehicle, the operating mode of the vehicle being one of moving and non-moving. The techniques also include estimating, at the controller, a temperature of the axle assembly based on the initial axle assembly temperature and the vehicle operating mode using an axle temperature model.

摘要： A method and a system for notifying an attribute of an Internet Protocol (IP) address and a Serving Gateway (SGW) are disclosed. When an SGW is taken as a User Equipment's (UE's) SGW, the new SGW can be notified of an attribute of the UE's IP address. The technology of notifying an attribute of an IP address in the disclosure can ensure that the new SGW can learn the attribute of the UE's IP address in time when the new SGW is taken as the UE's SGW. Therefore, a charging gateway function entity connected with the new SGW can accurately charge the UE according to the attribute of the IP address.

摘要： Disclosed is a miniature moving-coil speaker comprising a magnetic circuit system, a vibration system, and an auxiliary system for fixing the magnetic circuit system and the vibration system. The vibration system comprises a diaphragm and a voice coil integrated with the diaphragm. The auxiliary system comprises a plastic enclosure. The diaphragm is installed correspondingly at one end face of the enclosure, while the magnetic circuit system is installed at the other end face of the enclosure opposite the diaphragm; also: a flexible circuit board is arranged on the end face of the enclosure where the magnetic circuit system is installed, and the voice coil is electrically connected to the flexible circuit board. The design reduces product installation height, while at the same time facilitates wire-leading and wire-combing for the miniature moving-coil speaker, and simplifies product design.
