Abstract: Temperature and motion detection system (TMDS) for detecting the presence of a living being, such as a baby or animal, left in a vehicle after the engine or electric motor has been shut off to help reduce harm or deaths from extreme temperatures. The TMDS, or parts thereof, include the ability to sense and differentiate ambient vehicle passenger compartment or cabin temperature from that of the living being (body heat) and also sense the presence or the motion of the living being. Upon comparing sensor inputs, or parameters related thereto, to one or more limits programmed or set for, or by, a control unit of the TMDS, the system activates alert subsystems in the vehicle, such as the alarm, horn, lights/flashers, lowering electric windows, unlocking doors, or the like to help decrease the occurrence of deaths when temperatures approach dangerously high or low values.

Abstract: A deicing fluid recovery system for aircraft deicing apparatus includes a storage tank from which a deicing fluid/water deicing mixture is pumped through a line heater to a deicing fluid distribution and collection zone for application to the wings and fuselage of aircraft. Expended deicing fluid is collected in a drainage system incorporated into a concrete or asphalt pad and directed to a sump. Upon accumulation of a sufficient quantity, the diluted used deicing fluid is pumped to a sludge tank. Solids and free water are separated by settling and filtration processes in the sludge tank. The filtered deicing fluid mixture is heated through sequential heat exchangers and directed to a regenerator. The deicing fluid mixture is leaned by a dehydration process in the regenerator in which the mixture is heated and compressed air is injected to exhaust water from a stripping column. The lean deicing fluid flows over an overflow weir into an accumulator.
