Abstract: A wrist-worn bracelet displaying health indicators constructed to ensure correct and optimal fitting on a wrist of user for the effective detection of functioning of human body. The wrist-worn bracelet includes a first wristband portion and a second wristband portion connected to the first wristband portion to form a closed loop. The second wristband portion includes at least one inwardly-bent portion. A contour of the at least one inwardly-bent portion is capable of being changed by heating and bending the inwardly-bent portion so that an inner diameter of the closed loop is adjustable.

Abstract: A method for unlocking an electronic device stores a user fingerprint in a storage device and presets account information corresponding to each application for each of the user fingerprints. The method further receives fingerprint data input from the electronic device. When the received fingerprint data matches one of the user fingerprints, the account information corresponding to the matched fingerprint for each of the plurality of applications is confirmed. The method further replaces a default account information of each of the plurality of applications stored in the storage device by the confirmed account information corresponding to the matched fingerprint for each of the applications, and the electronic device is unlocked.

Abstract: A bracelet includes a first wristband portion having a first connecting end and a first lock end opposite to the first connecting end, a second wristband portion having a second connecting end and a second lock end opposite to the second connecting end, and a lock mechanism. The seconded connecting end is rotatably connected to the first connecting end. The first lock end is connected to the second lock end, thereby locking the first wristband portion and the second wristband portion together to surrounding a receiving space for receiving a user's wrist.

Abstract: A method for logging in to an application program of an electronic device presets a plurality groups of account information of the application program, and presets fingerprints corresponding the plurality of groups of account information in a storage device. When the application program is executed and a user interface of the application program is displayed, the method receives fingerprint data input. When the received fingerprint data matches one of the fingerprints, the method further confirms a group of account information corresponding to the matched fingerprint, and logs in to the application program using the confirmed account information.

Abstract: In a method for projecting pictures onto a projection using a projector device, the method triggers a camera of the projector device to capture an image of the projection screen displaying a first picture, and obtains the image of the projection screen from the camera. The method obtains a position, a size and a slant degree of the second picture, and notifies the second electronic device to send the second picture to the projector device. The method processes the second picture according to the obtained position and size and slant degree, and integrates the first picture and the second picture by processing the second picture sent from the electronic device according to the obtained position, size and slant degree, and triggers the first projecting unit to project the integrated picture onto the projection screen.

Abstract: In a method for controlling a projection screen using a projector device, the method builds a datasheet comprising a relationship between a mouse icon and a mouse operation, and triggers a camera to capture an image of the projection screen comprising a user interface projected from the electronic device onto the projection screen, and obtains the image of the projection screen from the camera. The image of the projection screen is used to obtain a position of the mouse icon in the image of the projection screen, and a mouse operation corresponding to the mouse icon is queried. The queried mouse operation is performed on the projector device according to the obtained position of the mouse icon, and an image of the queried mouse operation is projected from the projector device onto the projection screen.
