  • Patent number: 11599851
    Abstract: A method is performed by using a master smart scale with a master-slave mode, a remote communication device and a slave smart scale to manage multiple chemicals from a remote place. The master smart scale performs an initialization procedure to obtain an initial weight of one chemical; generate an identification information by reading a radio frequency tag of the chemical; use the identification information to inform the remote communication device to open an input page for users to input a basic information into the master smart scale; and mark the basic information and the initial weight with the identification information. In the master-slave mode, the master smart scale allows receiving the information of the chemical from its slave smart scale. For inquiry, a specific page is opened with the remote communication device to receive and display a statistical data generated from the master smart scale.

  • Patent number: 10523057
    Abstract: The present application provides a wireless charging module and a modularized sensing device therewith. A first charging unit is disposed around the inside of the wireless charging module for wirelessly charging a sensing module. Without introducing a transmission line as an electricity transmitting medium, the sensing module can be directly disposed inside and charged by the wireless charging module, which improves flexibility of implementation. Further, since the first charging unit is configured to surround the inside of the wireless charging module shaped as a bowl structure, the sensing module can be simply disposed into the bowl structure and wirelessly charged by the surrounding first charging units, which saves the inconvenience of setting the sensing module to a specific location or area for stable wireless charging and increases effective charging angles.
