초록 ▼

A safety apparatus for a portable tool having an internal combustion engine has at least one accelerometer providing a measurement of an acceleration of the portable tool in at least one plane or axis. An electronic controller is connected to an output of the accelerometer so as to receive analog or digital information. A generator is driven by the internal combustion engine so as to supply power to the accelerometer. A management card processes the analog or digital information so as to activate the system acting on an ignition exciter box so as to nearly instantaneously stop the internal combustion engine when the acceleration of the portable tool exceeds a predetermined level.

대표청구항 ▼

1. An apparatus comprising: a portable tool having an internal combustion engine, said portable tool having an electronic ignition exciter box;at least one electronic accelerometer providing a measurement of an acceleration of said portable tool in at least one plane or axis, the electronic accelerometer having an output, the output of the accelerometer being analog or digital electrical information;an electronic controller connected to said output of the electronic accelerometer, said electronic controller having an electronic management card; anda generator driven by said internal combustion engine, said generator supplying electrical power to the electronic accelerometer and to said electronic management card, said electronic management card processing the analog or digital electrical information so as to activate a system acting on said electronic ignitor exciter box so as to nearly instantaneously stop said internal combustion engine when the measurement of the acceleration exceeds a predetermined level. 2. The apparatus of claim 1, said system acting on a programmed spark advance of said internal combustion engine so as to cause said internal combustion engine to stop, said electronic ignition exciter box having an electronic card therein, said system communicating with said electronic card of said electronic ignition exciter box. 3. The apparatus of claim 1, the electronic accelerometer providing the measurement of acceleration in at least two axes. 4. The apparatus of claim 3, the electronic accelerometer being a three-axis accelerometer. 5. The apparatus of claim 1, the electronic accelerometer comprising: a first single-axis accelerometer; anda second single-axis accelerometer having an axis of measurement different than an axis of measurement of said first single-axis accelerometer. 6. The apparatus of claim 1, said portable tool having a center-of-gravity, the electronic accelerometer positioned adjacent said center-of-gravity. 7. The apparatus of claim 1, said portable tool selected from the group consisting of chain saws, circular cross-cut saws, drills, disc grinders, and planers.
