Abstract
A handheld power tool (100) comprising at least one orientation sensor (150) is provided. The handheld power tool (100) is operatively connected to a controller (160; 210) and said controller (160; 210) is configured to receive orientation data from the at least one orientation sensor (150), wherein the orientation data comprises information associated with an orientation of at least a portion of the handheld power tool (100) and to determine operational data based on the orientation data, said operational data representing work performed using the handheld power tool (100). The operational data is determined by determining the orientation of the power tool based on the received orientation data from the at least one orientation sensor (150).
Claims18
A handheld power tool comprising:
- an orientation sensor;
- a power unit sensor configured to generate power data indicative of a power being output by the handheld power tool;
- and
- a time measurement system configured to generate time data;
- wherein the handheld power tool is configured to be operatively connected to a controller and a position determining device, wherein the controller is configured to:
- receive orientation data from the orientation sensor, wherein the orientation data comprises information indicative of an angle of operation of a portion of the handheld power tool;
- receive position data from the position determining device, the position data indicating a position of the handheld power tool;
- receive the time data generated by the time measurement system;
- determine a duration of time that the handheld power tool operated above a power threshold during performance of an operation based on the time data at a location indicated by the position data and the power data;
- and
- determine, based on at least the orientation data, the position data, and the duration of time that the handheld power tool operated above the power threshold, that an operation has been performed to fell a tree, a tree location for the tree, and a thickness of the tree that has been felled.
A method for a controller operatively connected to a handheld power tool, the handheld power tool comprising an orientation sensor and a power unit sensor, the method comprising:
- receiving power data indicative of a power being output by the handheld power tool;
- receiving orientation data from the orientation sensor, wherein the orientation data comprises information indicative of an angle of operation of a portion of the handheld power tool;
- receiving position data from a position determining device, the position data indicating a position of the handheld power tool;
- receiving time data from a time measurement system;
- determining a duration of time that the handheld power tool operated above a power threshold during performance of an operation based on the time data at a location indicated by the position data and the power data;
- and
- determining, based on at least the orientation data, the position data, and the duration of time that the handheld power tool operated above the power threshold, that an operation has been performed to fell a tree, a tree location for the tree, and a thickness of the tree that has been felled.
A handheld power tool comprising:
- an orientation sensor;
- and
- a power unit sensor configured to generate power data indicating a number of revolutions of a working assembly of the handheld power tool;
- a time measurement system configured to generate time data;
- wherein the handheld power tool is configured to be operatively connected to a controller and a position determining device, wherein the controller is configured to:
- receive orientation data from the orientation sensor, wherein the orientation data comprises information indicative of an angle of operation of a working assembly of the handheld power tool;
- receive position data from the position determining device, the position data indicating a position of the handheld power tool;
- receive the time data generated by the time measurement system;
- receive the power unit sensor data and determine a relationship of the power data to a revolutions per minute (RPM) threshold profile during performance of an operation based on the time data at a location indicated by the position data and the power data;
- and
- determine, based on at least the orientation data, the position data, and the relationship of the power data to the RPM threshold profile, that an operation has been performed to fell a tree, a tree location for the tree, and a thickness of the tree that has been felled.
