초록

Fuel gauges for fuel supplies for fuel cells are disclosed. Each fuel gauge has a property that is readable by an electrical circuit. These properties are related to the remaining fuel in the fuel supplies. These properties include, but are not limited to, electrical capacitance, magnetic, semi-conducting resistance, bi-metal resistance, and oscillating magnetic field. These fuel gauges are functional at any fuel supply orientation.

청구항

We claim: 1. A fuel gauge adapted for use with a fuel supply and an electronic equipment powered by a fuel cell, said fuel gauge comprises: means for establishing a remaining fuel level by measuring a property between a first location movable within the fuel supply and a second location on the fuel cell or on the electronic equipment, wherein the property is readable by an electrical circuit and is related to the amount of fuel remaining in the fuel supply; and means for accounting for the effects on the property caused by at least one material disposed...
