Latest Patents

Dart's latest patents include a method and apparatus enabling archery practice. One embodiment of his invention features an archery practice device that projects a moving hunt scene on a screen. This device utilizes a continuous plane of infrared (IR) light positioned before the screen. When an arrow carrying a reflector penetrates this light plane, it is detected, and IR illumination is reflected back toward the archer and a full-screen radiation detector. The detector generates a full-screen signal indicating the point of arrow impact on the screen. Upon detecting the arrow, the moving scene is frozen, and a hit zone image is projected to indicate the arrow impact point relative to the frozen scene. Importantly, the arrow does not penetrate the screen but drops vertically downward adjacent to the bottom of the screen.

Another embodiment of his invention simulates dynamic targets, such as those encountered during an animal hunt. This device employs a video disk containing multiple hunting scenes projected via a video projector onto a vertical screen. The screen's size simulates the area typically viewed by an archer during a hunt. A light source emitting a spectrum outside the humanly visible range is provided adjacent to the screen. When arrows penetrate this light field, they reflect light to a detector sensitive to that spectrum. The detector generates a full-screen signal indicating the pixel areas where light reflection occurs. Upon detecting such reflection, the scene frame is frozen, and a hit zone image is projected to indicate the arrow impact point relative to the frame image.
