Data collection apparatus and method
First Claim
1. A lawnmower comprising:
- a frame;
an engine supported by the frame;
a mower deck supported by the frame;
a cutting implement disposed below the mower deck and rotationally driven by the engine;
a self-contained modular monitoring system for recording operational data of the lawnmower, the monitoring system including;
a microprocessor;
a memory;
an accelerometer for measuring impact force data of the lawnmower;
a signal conditioning circuit connecting the accelerometer to the microprocessor for transferring the impact force data, the signal conditioning circuit filtering the impact force data and providing filtered impact data that is scaled to parameters of the lawnmower, the filtered impact data being saved in the memory; and
a GPS receiver for collecting position data of the lawnmower, the GPS receiver being connected to the microprocessor and the position data being saved in the memory.

Abstract
A monitoring system for an outdoor power implement. The monitoring system comprises an accelerometer, a GPS receiver, a processing module, and a storage device. The accelerometer collects impact force data of the outdoor power implement. The GPS receiver collects position data of the outdoor power implement. The processing module is coupled to the accelerometer and the GPS receiver and has a filter module operable to receive the impact force data from the accelerometer, filter the impact data, and provide filtered impact data. The filter module comprises a resistor capacitor filter circuit having a cutoff frequency at 50 Hz. The processing module also has a data extraction module operable to receive the positioning data from the GPS receiver. The storage device is coupled to the processing module and is operable to record the filtered impact data and the positioning data. The outdoor power implement may include a lawnmower.
