  • Laser football down marker system and method
    Patent number: 11395952
    Abstract: A football down marker system, including a first pole bearing a first laser, a first multilayer reflector, a first level and a first processor. The system also includes a second pole bearing a second laser, a second multilayer reflector, a second level and a second processor, wherein the first laser is complementary to the second multilayer reflector and the second laser is complementary to the first multilayer reflector, and wherein each processor calculates an average distance between a respective laser and its complementary multilayer reflector, and wherein each processor calculates a difference between a laser incidence on a first layer versus incidence on a second layer of the multilayer reflectors to determine a line of sight by a coincidence of the incidence.
