4results about How to "Lower confidence" patented technology

This invention relates to the field of electronic clock technology, specifically disclosing a method and system for calibrating the timing accuracy of electronic clocks based on data fitting. The method includes: based on the timing characteristics of the electronic clock, performing temperature difference mapping on the extreme value offset of the jitter amplitude distribution set to solve for the sensorless temperature estimate; combining the nominal period of the real-time pulse segment sequence of the electronic clock, matching and calibrating the temperature estimate to establish a temperature-offset mapping table; performing temperature difference mapping again on the current pulse segment to obtain the real-time temperature estimate, and obtaining the interval reference offset based on the interval positioning of the mapping table; configuring a compensation step size for the jitter amplitude according to the reference offset, generating a dynamic compensation step size, and adjusting the phase of the accumulated count value to obtain the single-cycle refresh value; using this as a correction reference, performing timing calibration on subsequent pulses of the electronic clock, and outputting the final working signal of the electronic clock; this invention can improve the timing accuracy and temperature tracking response capability of electronic clocks under conditions without an external temperature sensor.

A dual-engine collaborative retrieval and bidirectional real-time interaction method and system. Step one: vector retrieval generates candidate set and expands locally in graph atlas; Step two: relationship path encoding attention fusion generates reconstructed query vector; Step three: vector semantics, graph structure and cross-engine cross joint confidence iteratively propagate along the graph to convergence; Step four: cross-engine neighborhood consistency index (CECI) detects semantic drift and structural noise, and false consensus detection calculates consensus reliability index (CRI) through embedded vector attribution decomposition to identify false consensus of two engines simultaneously overestimating the same entity and decouple calibration; Step five: dynamic adjustment of dual-engine collaboration mode in interview stage; Step six: full-duplex communication protocol (WebSocket) establishes retrieval-feedback closed loop; Step seven: graph-vector mutual calibration eliminates hub bias and popularity bias. Under 2156 queries, F1 rises from 82% to 95%.

This invention discloses an acoustic imaging device and method for detecting pavement voids, belonging to the field of non-destructive testing technology for roads. The device includes an excitation module, an accelerometer, a multi-aperture reconfigurable microphone array module, a synchronous acquisition module, a sound field feature construction module, a multi-source fusion module, a geometric inversion module, and a coordinate registration and imaging output module. The excitation module applies a transient impact to the pavement under test. The accelerometer acquires the acceleration signal at the excitation point, and the multi-aperture reconfigurable microphone array module acquires multi-channel near-field sound pressure signals around the excitation point. The sound field feature construction module determines the impact initiation time and impact energy based on the acceleration signal at the excitation point, and performs time alignment, energy normalization, and feature extraction on the multi-channel near-field sound pressure signals. This invention improves the stability and quantitative characterization capability of pavement under-slab void detection, and is suitable for detecting under-slab voids in cement concrete pavements, composite pavements, and bridge deck paving.
