Abstract: A radiant compensated thermometer, which uses a pair of parabolic-shaped radiation shields that are spaced-apart from one another. An upper shield is positioned to intercept the sunlight from impacting on a lower shield; both shields have an outer substantially reflective surface and an inner substantially non-reflective surface. A temperature sensor is positioned in a “dead space” near the inner surface of the lower shield, which is cooler than the other areas of the device.

Abstract: An air heater is provided for use in buildings or other structures. The air heater uses infrared lamps to generate a temperature rise in a forced air chamber that contains several infrared lamps, in which two ends of the chamber act as an inlet and an outlet, and in which the chamber has a highly reflective interior surface that reflects the light being emitted by the lamps to multiply the thermal effect of the infrared light sources. An alternative embodiment uses a closed chamber, in which the temperature rise causes the unit to act as a detonator.

Abstract: An antenna mast adapter is provided capable of holding several different antennas in place that mounts onto a vertical antenna mast. A crossarm that runs perpendicular to the mast is a main member of the antenna mast adapter and provides at least two mounting plates to which individual antennas are mounted, either using mechanical mounting means or magnetic mounting means. The crossarm is generally designed to provide these mounting plates at the extreme ends of the crossarm, thereby providing an air gap between the antennas and the mast. The crossarm can be constructed from different shaped materials, and in one preferred embodiment, the crossarm includes openings to reduce the wind resistance of the crossarm. The antenna mast adapter provides mounting points for several different antennas, each of which is connected to an individual radio via a waveguide.

Abstract: A temperature monitor comprising two circular metallic plates which are disposed in the horizontal plane in a spaced-apart configuration, the upper plate having a mirrored top surface and a black bottom surface, the lower plate having a black top surface and a mirrored bottom surface, and a temperature sensor mounted in the space between the two plates. The plates are fastened in the spaced-apart configurataion by use of nylon bolts, and the temperature sensor is mounted using nylon or other electrically insulating washers. The entire apparatus is mounted on wood or PVC supports. A thin layer of temperature-stabilized air is traped in between the two plates, allowing the temperataure sensor to achieve great accuracy.
