A data management method for a USB device includes the steps of: sampling an analog input signal, and generating digital sample data corresponding to samples of the analog input signal; monitoring the number of the digital sample data generated within a predefined time interval; if the number of the digital sample data generated at the end of the predefined time interval matches a predetermined value, providing the digital sample data to a USB host; and if the number of the digital sample data generated at the end of the predefined time interval does not match the predetermined value, processing the digital sample data such that the number of the processed digital sample data matches the predetermined value, and providing the processed digital sample data to the USB host. A USB device including a data management module for implementing the data management method is also disclosed.

This invention relates to a container with a self-contained evacuation lid. The container is provided for preserving food and is closed on the top by the evacuation lid. The lid includes a piston rod to be reciprorated up and down such that air inside the container is pumped out. An elastic element is fitted under the piston rod to bias a depressed part of the lid upward for an upward stroke when the depressed part is released after the downward movement. A valve rod is pulled to release the vacuum of the container for removal of the lid.

An apparatus includes an electronic device and an adapter. The electronic device includes an electrical connector, and a processor having a detecting pin coupling to the electrical connector. The processor is operable so as to communicate through the electrical connector using a first signaling protocol when the detecting pin has a first state, and using a second signaling protocol when the detecting pin has a second state. The adapter includes first and second adapter connectors serves to change the detecting pin of the processor of the electronic device from the first state to the second state.

The welding filter device includes a light sensor, a microprocessor, a liquid crystal display, and a user interface. The light sensor senses light to generate a welding signal and a light source intensity signal. The microprocessor comprises a determining module, a control module, a regulating module, and a storage module. The determining module receives the welding signal and determines whether to activate a welding mechanism. The control module receives the light source intensity signal and outputs a control signal. The liquid crystal display presents a first display status according to the control signal. The user interface is used to generate a setting signal; wherein when the liquid crystal display presents the first display status, the regulating module receives the setting signal to regulate the settings so that the liquid crystal display presents a second display status. Furthermore, a method for controlling the welding filter device is also disclosed herein.
