摘要： Disclosed are a droplet ejection device and method using an electrostatic field. The droplet ejection method includes: setting a separate electric field direction in each of a plurality of nozzles; supplying one of ink and ink containing particles to each nozzle; and forming and ejecting a plurality of separate ink droplets. The droplet ejection device includes a deposition part having electrode layers and insulating layers deposited toward a nozzle. Therefore, it is possible to readily perform droplet ejection without a heater or diaphragm vibration device. In addition, it is possible to reduce impact applied to the ink and obtain good print quality, since the ink is ejected using the electrostatic field.

摘要： A 3D depth imaging method and system are disclosed. The 3D depth imaging method involves radiating light at a measurement target object using a projection means and imaging the light using an image receiving means, and includes the steps of assigning a unique transmitting side address to a signal corresponding to each pixel of the projection means to encode the signal; projecting multiple light patterns at the projection means to transmit the signal; receiving the encoded signal at the image receiving means; separating the received signal to restore the address; and determining a pixel position of the object using the transmitting side address and the restored address. With the 3D depth imaging method and system, it is possible to exactly separate signals received by the image receiving means even when the signals are overlap and the geometrical structure of the object varies, and it is also possible to obtain a depth image that is robust against ambient environmental noise.

摘要： Disclosed is a technique for obtaining an estimate and variance of each variable based on a constraint manifold. Particles (or samples) are sampled in order to filter and fuse ambiguous data or information on at least one state variable of a system using the particles. The sampling is carried out in consideration of an influence which non-linearity of the constraint manifold of a system model, an observation model or another system model exerts on a probability distribution of the state variable. With this construction, it is possible to reduce decrease of fusion and filtering performance, decrease a Gaussian approximation error, and detect mismatched information.
