The calculation method includes: step 1: establishing a deterministic model for an external substructure reinforcement system, and generating seismic ground motion samples and structural samples by random sampling; establishing a probabilistic hazard model based on the seismic ground motion samples; generating a probabilistic vulnerability model based on interfacial shear stresses; establishing a total probabilistic loss expectation model by different seismic ground motion intensity levels; and using the total probabilistic loss expectation model to obtain an annual average probabilistic seismic loss of the external substructure reinforcement system based on the interfacial shear stresses. The calculation method can realize classified calculations of the seismic loss of the external substructure reinforcement system. Compared with the traditional seismic loss calculation method, the calculation method is more efficient in calculation.
Disclosed is a wearable haptic feedback device for human-robot formation control, including an interactive interface module and a main control module, wherein the interactive interface module includes an input module and a wearable haptics feedback module; the wearable haptics feedback module includes an extrusion force feedback module, a shear force feedback module, and a vibration feedback module, and the main control module controls each module and receives operation instructions. The device can be wirelessly deployed on an arm of a user, and provide feedback on the formation change, motion guidance, and obstacle detection of the human-robot formation by generating three haptic feedback signals: extrusion, shearing, and vibration. A haptic channel is more advantageous in providing feedback to the user on understanding capability and task situation of external limbs, which can play a unique role in reducing the difficulty of human-robot interaction and creating highly immersive operation experience for the user.
The present application relates to a pixel driving circuit and a pixel driving system. The circuit receives input signals, which comprise a slope signal, a grayscale voltage, a sampling signal and a reference signal. The circuit comprises: a first switch unit, which is configured to sample a grayscale voltage according to a sampling signal, and store the sampled grayscale voltage in a capacitor component; the capacitor component, which is configured to store the sampled grayscale voltage sampled by the first switch unit; a comparison component, which is configured to compare a slope signal with the sampled grayscale voltage, and generate a pulse width modulation signal according to a comparison result; and a display component, which adjusts light emission brightness on the basis of the pulse width modulation signal. Thus, the strict frequency and time sequence requirements of a control signal in a digital driving mode can be avoided, and the phenomena of pitting and non-uniformity in an analog driving mode can be solved.
