Abstract: A system for a real time programming of a battery agnostic Battery Management System (BMS) including a processor of a BMS programming server node connected to a controller over a network and configured to host a machine learning (ML) module and a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to: receive sensory data from a sensor array attached to a battery module having a BMS coupled to the controller; parse the sensory data to derive a plurality of features; query a local BMS database to retrieve local historical BMS data collected from the battery module; generate a feature vector based on the plurality of features and the historical BMS data; and provide the feature vector to the ML module for generating a predictive model configured to output a BMS programming parameter for re-programming of the BMS.

Abstract: A focal-length measuring apparatus for a sub-wavelength optical imaging device includes a laser, a beam-expanding and collimating system, a sub-wavelength optical imaging device, and a nanoscale stepped height standard sample block. The nanoscale stepped height standard sample block is connected to a power device, and the power device is connected to a computer control system. The nanoscale stepped height standard sample block is coated with a photoresist and includes a plurality of steps arranged at equal intervals Among all the steps, the heights of the steps gradually increase from a middle step to an upper side, and the values of the corresponding focal lengths decrease. While, the heights of the steps gradually decrease from the middle step to a lower side, and values of corresponding focal lengths increase. A wavelength of the laser is equal to a designed wavelength of an input light source of the sub-wavelength optical imaging device.
