2results about How to "Less hardware" patented technology

The application relates to the technical field of battery detection, and discloses a battery pack charging and discharging state detection method. Since a current sensor is not additionally arranged to detect the current of the battery pack, only the voltage signal of the battery pack needs to be detected, and then the charging and discharging state of the battery pack can be analyzed through an algorithm. The method reduces additional hardware, simplifies circuit design, and reduces cost and complexity.

This invention relates to the field of orthodontic appliance manufacturing technology, and discloses a cutting path compensation method, system, and cutting system for orthodontic appliances. The cutting path compensation method includes: acquiring a module to be cut, the module including a carrier, a dental model fixed on the carrier, and a shell-shaped orthodontic appliance to be cut formed by hot pressing a diaphragm onto the dental model, the dental model including a positioning block protruding inwards from the dental arch, the dental model being fixed to the carrier by the positioning block; detecting the spatial pose of a detection surface and a reference surface based on a distance detection device; wherein the detection surface is the upper surface of the positioning block, and the reference surface is the bearing surface of the carrier; calculating the difference between the spatial pose of the bearing surface and the spatial pose of the detection surface, and compensating the initial digital cutting path corresponding to the dental model based on the difference to obtain a new digital cutting path.
