Latest Patents

One of Raposa's latest patents is titled "Control circuitry for high speed video camera operation." This invention is designed to control a video camera specifically for underwater high-speed photography. The device includes a series of spaced break screen or sense coil members, a projectile that is launched through these members, and a video camera that operates at a predetermined timing upon the release of the projectile. Additionally, a source of illumination is incorporated to enhance the video photography. The control circuitry utilizes a time delay programmed into a Programmable Array Logic (PAL) to receive trigger information and generate a timed signal for the camera's operation. Another significant patent is the "Device for sensing projectile velocity in an underwater environment." This device features multiple evenly spaced voltage coil members positioned in the projectile's path. Each coil member is equipped with a support frame and a magnetic coil, along with a sensing member that outputs a signal in response to the projectile's passage. The logic arrangement determines the velocity of the projectile by calculating the time difference between its passage through adjacent voltage coil members.
