Abstract: A computer-implemented method for building a diagnostic module for a physical system includes obtaining simulated healthy measurements by a physics-based simulation model of the physical system from measured input excitations to the physical system. The method includes training a generator model to generate realistic healthy measurements from the simulated healthy measurements and the measured input excitations, the training involving tuning the generator model based on an error between a generated realistic healthy measurement and a corresponding real measurement obtained from the physical system in response to each input excitation. The trained generator model is used to generate realistic faulty measurement data from simulated faulty measurements obtained by the physics-based simulation model.

Abstract: A Bluetooth sensing method for unlocking a door, applied to a system including an electronic device, an electronic door lock, and an authenticator connected to the electronic door lock. The method includes: the electronic device detecting that the distance between the electronic device and the authenticator is smaller than a pre-defined value, the electronic device setting up a Bluetooth communication connection to the authenticator; the processor initiates a mutual authentication process to the controller when the distance is smaller than a pre-defined value; the electronic device automatically transmitting an unlocking instruction to the authenticator; and the authenticator unlocking the electronic door lock according to the unlocking instruction.

Abstract: A portable electronic device includes a base material, a fixing-cover and conductive terminals. The base material has first contact-pads and second contact-pads. The fixing-cover is disposed on a first surface and exposes the first contact-pads. The fixing-cover has a clamp portion. The terminals are disposed on the second contact-pads, wherein a first end of each the terminal extends out of the fixing-cover. A second end leans against the fixing-cover. A central portion is located between the two ends, wherein the bottom of the central portion bulges and contacts the corresponding second contact-pad, and the two ends can swing relatively to the base material around the bottom of the central portion as the pivot. The central portion has a positioning portion formed in direction facing the opening and the positioning portion is embedded in the opening.
