  • Publication number: 20190375573
    Abstract: A container and cap assembly has a container and a cap. The cap covers the container, and has an inner cover, a piston, a slider, and an outer cover. The piston is disposed in the inner cover, and is axially movable therein. The slider is mounted on the piston, and is radially movable to move the piston. The outer cover receives the inner cover, the piston, and the slider. The outer cover is rotated in a first direction to close the container, and is continuously rotated in the first direction to move the slider radially and reciprocatingly so as to move the piston axially and reciprocatingly. The piston is moved to exhaust air from the container to produce a vacuum or approximate vacuum in the container. Therefore, contents in the container are protected from moisture without a desiccant material.

  • Publication number: 20190319747
    Abstract: A multi-member Bluetooth device includes: a main Bluetooth circuit capable of bidirectionally communicating with a remote Bluetooth device through a first Bluetooth communication circuit; and an auxiliary Bluetooth circuit capable of communicating with the main Bluetooth circuit through a data transmission circuit. While the main Bluetooth circuit utilizes the first Bluetooth communication circuit to communicate with the remote Bluetooth device, the auxiliary Bluetooth circuit utilizes a second Bluetooth communication circuit to sniff packets transmitted from the remote Bluetooth device. When detected that the auxiliary Bluetooth circuit has missed packets transmitted from the remote Bluetooth device, the main Bluetooth circuit transmits missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.
