Abstract: The present invention relates to an odor extractor apparatus to be installed in a toilet, particularly to the type of toilet assembly that has both a bowl (3) and a water tank (2). Although this invention uses a mechanical fan (9) to force the gases through an exhaust pipe (12), as other inventions do, it does it by an innovative basic architecture. In essence it comprises an exhaust system activated by the user presence, plus a water-air duct segment (1) inserted between the water tank (2) and the bowl (3). This duct segment (1) also presents an output (7) that allows the unpleasant gases but not the water, to flow into the aforementioned exhaust system. This apparatus may well be retrofit to used toilets in the field or acquired pre-installed to factory new units.

Abstract: A wheel mounted data logger has an odometer for mounting at a hub of a wheel of a vehicle and response to turning of the wheel, an hourmeter for mounting on a structure of the vehicle and response to running of an engine of the vehicle, and microcontroller for mounting on the vehicle and receiving, recording and transmitting the responses of the odometer and hourmeter. The odometer, hourmeter and microcontroller are mounted on the vehicle as a unit preferably by adhesive.
