Abstract: A buffer assisted data storage method and system has built-in fingerprint recognition function. Recognized data is provided with a high hit-rate in a short time with the assistanace of a buffer, when a user processes his/her identity recognition through the built-in fingerprint recognition module of the data storage device. As a result, the entire identification and verification process is faster and more efficient. In addition, with the aim of enhancing flexibility of usage, an operation setup interface is introduced to optimize the overall performance of the buffer.

Abstract: A hinge structure for use in an electronic device such as a digital camera for connecting two elements and making the two elements turn against each other. A gear unit is provided, which has two gears engaging with each other and turning in opposite directions. The two gears connect respectively with the two elements. When one element is turned in one direction, through the transmission of the gear unit, another element will be driven to turn in the opposite direction, to thereby change the angle between the two elements and enhance picture taking flexibility.

Abstract: A digital camera with rotatable components is disclosed. In the front of camera there is provided a lens, a flash, and a viewfinder, while in the rear thereof there is provided a liquid crystal display (LCD) corresponding to lens, a control button, and the rear of viewfinder. Control button is operable to press for rotating lens, flash, viewfinder, and LCD in the same direction and into a desired angle with respect to an object. Next a shutter button on the camera is operable to press for taking a picture. This camera has the benefits of ergonomic, precise picture taking, and full covering of the object by flash.
