The power saving method of a touch screen for a mobile terminal includes determining whether a touch panel is contacted by controlling light emitting elements to emit light with a first scan speed and detecting whether light is received by light receiving elements; and decreasing, if the touch panel is determined not to be contacted for a predetermined time duration, a scan speed from the first scan speed to a second scan speed after lapse of the predetermined time duration. Therefore, if a contact occurs within the predetermined time duration, the contact is detected by executing the scan with the first scan speed, and if no contact is detected before lapse of the predetermined time duration, the scan speed is decreased, whereby electric current waste due to the scan can be minimized.

Abstract: The invention provides a snap down lock and a release valve control mechanism for a vacuum food container. The vacuum food container includes a cover and a base in tight connection with the cover to form a box for storing food. A snap down lock is provided between the cover and the base. The snap down lock depresses a plug and a spring inside a U-shaped recess on the base using a corner of its square block, blocking its vent. At the same time, the snap down lock depresses a retractable spring switch provided on the base, starting a motor vacuum pump to draw out the air inside the box. Once the square block corner of the snap down lock departs from its depressing position and releases its depression on the plug and the spring, the restoring force of the spring pushes the plug out of the sealing position on the vent. The box is then in connection with the atmosphere via the vent.
