  • Hydrogen generation from water split reaction
    Patent number: 6582676
    Abstract: A method of producing Hydrogen by reacting a metal selected from the group consisting of Aluminum (Al), Magnesium (Mg), Silicon (Si) and Zinc (Zn) with water in the presence of an effective amount of a catalyst at a pH of between 4 and 10 to produce Hydrogen. The catalyst or other additive is selected to prevent or slow down deposition of the reaction products on the (impair reactions with the) metal that tend to passivate the metal and thereby facilitates the production of said Hydrogen.

  • Vehicle weight and cargo load determination using tire pressure
    Patent number: 6449582
    Abstract: A method for measuring the weight of a vehicle and/or of its load comprising measuring the temperature and pressure of at least a significant number of tires of said vehicle, a temperature standardized pressure based on a selected standardization temperature, summing the standardized pressures and determining weight of the vehicle and/or its load based on the sum of the temperature compensated pressures and a conversion factor.

  • Tire pressure sensor
    Patent number: 5675314
    Abstract: A pressure sensing system is formed by a sensor mounted one to rotate with each tire and adapted to sense the pressure in the tire and generate a signal corresponding to the tire pressure, a movable contact system is moved into an operative position only when the vehicle is stopped and provides power (if required) to the sensor and contacts to deliver the electrical signals indicative of the tire air pressure to the vehicle body where it may be displayed for the operator's convenience.
