  • Air-conditioned animal transporter
    Patent number: 6490995
    Abstract: An apparatus for transporting in an air-conditioned environment animals. The apparatus uses crushed ice to air-condition an insulator animal container at approximately 74 degrees Fahrenheit in ambient temperatures up to 120 degrees Fahrenheit for 12 hours on one twenty pound charge of ice. The preferred embodiment is self-contained providing storage for the animal, ice, and electric power for a ventilation fan plus food and water. The device operates on 12 volts DC and may serve to transport animals in enclosed motor vehicles and common carriers including airline. An intrinsically safety backup system will keep the animal cool, provided ice is present, upon failure of the ventilation fan. An alternate embodiment is described for use by animal handlers in mini-vans and the like.

  • Locomotive whistle controlled railroad grade crossing warning system
    Patent number: 6416021
    Abstract: A railroad grade crossing warning device designed to operate at un-guarded grade crossings without the need for expensive train detection sensors. The system utilizes the sound of an approaching locomotive horn or whistle to activate a warning at a grade crossing. The preferred device is self contained and is powered by solar panel and storage battery to provide a flashing strobe warning on the approach of a train.
