Abstract: A water sensing electrode circuit comprises a voltage source; first electrode; second electrode; first resistor; second resistor; and an inverting comparator with an internal reference voltage, Vc; wherein: said voltage source, first electrode, second electrode, first resistor and second resistor are connected in series; and the negative input of said voltage comparator is attached to the junction of said first and second resistor.

Abstract: A safety flag includes reflective material, a light source and a controller. The safety flag meets legal requirements when used for extended loads in vehicles in day and night use.

Abstract: Electronic Tags are mounted on swimmers to reduce their risk of drowning by identifying when their heads are underwater for periods of time which may indicate a dangerous submersion situation, and for triggering corresponding alerts and alarms. In this method, each monitored person is equipped with a lightweight electronic Tag worn on the body that communicates with monitors that issue the alerts and alarms, including audible and visible distress signals. The monitors, in turn, communicate the alarms to receivers used by supervisory personnel, such as lifeguards or parents. The invention may be used in aquatic environments, such as public recreation facilities, pools, waterfronts, and water parks, as well as in more private settings, such as homes, apartment buildings or hotels.

Abstract: An apparatus for securing construction structure loads to a trailer for transportation which employs adjustable tubes, tie down chains, chain binders, load pads and protective flanges. The load pads being the apparatus for transferring the tie down forces to the construction structure load and trailer bed without damaging the load. The protective flanges being the apparatus for preventing the load chains from damaging the edges of the construction structure load when the load is secured. The apparatus is placed on the top of a load with the load chains secured to the trailer at a vertical angle. The chain binders being the apparatus to tighten down on the load creating greater clamping force between the load and the trailer bed.
