Latest Patents

Holt holds a patent for a "Method and apparatus for optically measuring crimp frequency." This invention allows for the optical measurement of the primary crimp frequency of crimped materials by utilizing the pattern of light reflections produced by the waviness of the material. The method involves illuminating the material from one end at a shallow angle, creating a pattern of bright and shadowed areas. A reticon camera scans this light pattern, generating an amplitude-modulated output signal that corresponds to the light pattern. The frequency of this output signal is then measured to indicate the crimp frequency.
