運輸 Transport
This application provides a wall-climbing robot, relating to the field of robotics technology, which includes a rectangular frame, multiple driving components, and multiple swing arms. The multiple driving components are arranged circumferentially along the rectangular frame and are respectively fixedly connected to it. The multiple swing arms are drivingly connected to the multiple driving components in a one-to-one correspondence. The driving components are used to adjust the rotation angle of the swing arms relative to the rectangular frame, and the end of each swing arm furthest from the driving component is rotatably connected to a magnetic wheel. Each driving component individually controls its corresponding swing arm, thereby changing the spatial position and posture of the magnetic wheel at the end of the swing arm. Because each magnetic wheel is always independently adjusted to a posture that conforms to the local wall surface, the contact area is maintained at the designed fitting area. This minimizes the attenuation of the adsorption force, thereby reducing the risk of the wall-climbing robot falling off the surface.

基本通訊流程、電腦技術 Basic communication processes, Computer technology
This application provides an amplifier and a qubit measurement and control system, relating to the field of amplifier technology. The amplifier comprises an input matching circuit, a low-noise input stage module, and a gain stage module. The low-noise input stage module includes a first amplification unit and a first power supply unit, and the gain stage module includes a second amplification unit, a second power supply unit, an inter-stage matching circuit, and an output matching circuit. The first power supply unit is configured to supply power to the first amplification unit, and the second power supply unit is configured to supply power to the second amplification unit. By adopting a tightly coupled, integrated architecture of power supply and amplification units, each amplification unit in the amplifier is integrated with its corresponding power supply unit, allowing each power supply unit to directly supply power to its associated amplification unit. When scaling up the number of amplification units to accommodate the readout requirements of large-scale qubit arrays, only the number of parallel, integrated power-amplification units needs to be increased, eliminating the need for additional power interconnects routed across cryogenic stages.

Technology Field(s):
控制技術 Control
The present invention belongs to the field of integrated circuits and discloses a low-dropout regulator (LDO) that balances high full-band power supply rejection ratio (PSRR) with fast transient response. The LDO comprises a bandgap reference source and a first-stage feedforward ripple cancellation (FFRC) LDO. The reference voltage of the first-stage FFRC LDO is provided by the bandgap reference source, and an off-chip power supply is directly connected to the input node of the on-chip first-stage FFRC LDO via bonding wires. The clean voltage source output from the first-stage FFRC LDO is directly supplied to the input node of a second-stage flipped voltage follower (FVF) LDO, and the second-stage FVF LDO directly outputs a clean, fast-responding on-chip reference voltage. In this two-stage cascaded architecture, the first stage provides high PSRR and primary voltage regulation, while the second stage handles heavy-load driving and fast transient response, thereby achieving complementary performance. By utilizing feedforward ripple cancellation, the full-band PSRR is substantially enhanced—reaching peak values near -110 dB—without sacrificing bandwidth. Furthermore, by maximizing the quiescent current of the FVF LDO within the allowable load current range of the first-stage LDO, the output impedance of the FVF LDO can be reduced to below 10 Ω.

The present application discloses a piezoelectric energy harvesting interface based on excitation identification and maximum power point tracking. The interface includes a piezoelectric transducer, a reconfigurable power stage, an analog conversion module, a storage-and-matching module, a feature extraction engine, a detection module, and a controller. A positive-and-negative polarity vibration voltage is generated by the piezoelectric transducer and converted by the analog conversion module to obtain an input vibration waveform. The controller extracts features from the input vibration waveform via the feature extraction engine to obtain mapped features, which are then matched against the storage-and-matching module. Based on the matching result and a detection signal from the detection module sensing the piezoelectric transducer, the controller generates a control signal. The reconfigurable power stage determines a target topology mode according to the control signal and operates under the target topology mode to perform corresponding energy operations on the piezoelectric transducer. Embodiments of the present application can improve scenario adaptability and energy extraction efficiency, and can be widely applied in the technical field of piezoelectric energy harvesting.
