Abstract: An apparatus and a method for predicting a speed of a vehicle. The apparatus includes storage that stores past driving information of the vehicle. The apparatus also includes a controller that extracts feature information about a current state of the vehicle from the past driving information of the vehicle. The controller also generates a query corresponding to each target time point based on the feature information. The controller also determines forward information corresponding to each target time point by using each query. The controller also predicts the speed of the vehicle at each target time point based on the query corresponding to each target time point and the forward information corresponding to each target time point.

Abstract: An absorption type continuous neutral density filter controls an intensity distribution of a light beam from a laser to provide the intensity distribution of the light beam desired by an user. In the filter, the intensity distribution of the light beam is controlled by adjusting absorption of the light beam by the varying thickness of medium of the filter. This control of the distribution of the light intensity is accomplished by predefining the variance of thickness of the filter to a form required by the user. As a result, the continuous neutral density filter can be easily fabricated.

Abstract: An apparatus for making a high quality reflection type holographic optical element (HOE) using a single input laser beam, including a reflective mirror, a holographic photoplate having a photo emulsion layer on a surface nearest the reflective mirror, a cassette for retaining the reflective mirror and the holographic photoplate, and a refractive index matching fluid containing a light absorbent dye for absorbing an input laser beam. The cassette is immersed in the fluid so that fluid is retained between the photo emulsion layer of the holographic photoplate and a reflective surface of the reflective mirror. Parasitic interference patterns are suppressed by heating the refractive index matching fluid with the input laser beam, which causes a shift of the phase of the parasitic beams with respect to the phase of the beams responsible for recording the HOE. If the photo emulsion layer of the holographic photoplate consists of a dichromated gelatin (DCG), then a photo sensitizer agent (e.g.
