    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： Technologies are generally described for techniques useful in an interferometer system. In some examples, a system may include a first waveguide effective to propagate a first wave in a first mode. In some examples, the system may include a second waveguide effective to, in response to the first wave, propagate second and third waves in second and third modes, respectively. In some examples, the second waveguide may be effective to reflect the second and third waves off a reflection surface to produce first, second, third and fourth reflected waves. In some examples, the second waveguide may be effective to propagate the first and third reflected waves in the second mode and propagate the second and fourth reflected waves in the third mode.

    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： A video communication system that replaces actual live images of the participating users with animated avatars. The system allows generation, rendering and animation of a two-dimensional (2-D) avatar of a user's face. The 2-D avatar represents a user's basic face shape and key facial characteristics, including, but not limited to, position and shape of the eyes, nose, mouth, and face contour. The system further allows adaptive rendering for displaying allow different scales of the 2-D avatar to be displayed on associated different sized displays of user devices.
