摘要： A magnetic levitation imitation flame device includes a mounting base, a flame member, a positioning bracket, a first magnet, and a second magnet. The positioning bracket is fixed in the mounting base. The first magnet is disposed on the flame member. The flame member is disposed on the positioning bracket and protrudes outwards from the mounting base. The second magnet is fixed at a lower end of the positioning bracket. The first magnet and the second magnet are arranged up and down. Magnetic poles thereof facing each other have same polarity so that the flame member is levitated relative to the positioning bracket under a repulsive force of the first magnet and the second magnet. Thus, the flame member swings with big angle, naturally and realistically, and saves electric energy. In addition, an imitation flame lamp is also provided.

摘要： Technologies are generally described for systems and methods effective to implement particle removal. In one example, a method for at least partially removing particles from a region is generally described. In some examples, the method includes applying an electric field to a material to produce an acoustic wave from the material. The material may have a periodic piezoelectric coefficient. The method may include applying the acoustic wave to the region to produce an agglomeration. The agglomeration may include at least two of the particles. The method may further include at least partially removing the agglomeration from the region.

摘要： Avatars are animated using predetermined avatar images that are selected based on facial features of a user extracted from video of the user. A user's facial features are tracked in a live video, facial feature parameters are determined from the tracked features, and avatar images are selected based on the facial feature parameters. The selected images are then displayed are sent to another device for display. Selecting and displaying different avatar images as a user's facial movements change animates the avatar. An avatar image can be selected from a series of avatar images representing a particular facial movement, such as blinking. An avatar image can also be generated from multiple avatar feature images selected from multiple avatar feature image series associated with different regions of a user's face (eyes, mouth, nose, eyebrows), which allows different regions of the avatar to be animated independently.

摘要： A bootup device and method for an application program on a mobile equipment to improve the bootup speed of the application program on the mobile equipment. The bootup device has an application management module, that boots up a virtual machine module based on the application program to be run. A virtual machine module, loads codes of the application program and Just in Time (JIT) compilation results of a bootup process of the application program into a memory, search, in the JIT compilation results, for local JIT compiled codes corresponding to the bootup process code segment to be executed, and executes the found local JIT compiled codes when executing each bootup process code segment of the application program. A storage management module, store and reads the codes of the application program and the JIT compilation results obtained from the JIT compilation of the bootup process of the application program.
