Devices, systems, and methods for training baseball and softball batters, to identify types of pitched balls (fast ball, curve ball, slider and changeup) and locations (strike or non-strike zone) of pitched balls in order to increase hitting accuracy A motion sensor can be triggered by the leading foot of a pitcher. The motion sensor can use cone or fan shaped sensor to detect the passage of a pitched ball from the pitcher. When the motion sensor is triggered, a signal can be sent to a black out lens that blocks the vision of a hitter being trained to identify the types and locations of the pitched balls. The training includes changing the lens from transparent to opaque at selected distances between the hitter and the pitcher. Batters can be trained to keep their eyes on the pitched balls until the ball reaches the batter. Golfers can be trained to not have to look up when their club hits the ball, where the black out lens are go opaque when the golf swing passes into the motion sensor.

A method for manufacturing a liquid crystal aligning film includes preparing a multilayer structure in which a substrate, a conductive layer, a liquid crystal alignment layer, and a passivation film are sequentially provided, etching one area of the liquid crystal alignment layer by irradiating a pulse laser to the multilayer structure, and exposing one area of the conductive layer by removing the passivation film, wherein the pulse laser is irradiated to the liquid crystal alignment layer from the passivation film. The method is compatible with a continuous process.

A double-sided image sensor can capture images from two different perspectives during two different time intervals. For example, during a first time period, the image sensor captures the view relative to a first side of an electronic device containing the image sensor, but during a second time period, captures the view relative to a second side of the electronic device. To capture images from multiple views, the double-sided image sensor contains a layer of photodiodes which captures measurements from multiple directions. Moreover, the image sensor includes selectable attenuators (e.g., mechanical shutters or TN attenuators) which control what view the photodiodes are currently capturing. For example, when capturing an image from the backside of the electronic device, one of the selectable attenuators blocks light from striking the photodiodes from the front side, and as such, only the light entering at the backside strikes the photodiodes.
