Abstract
Techniques are disclosed for providing anti-theft protection for power tools. In one example of the techniques of the disclosure, at least one processor of a power tool receives, from an operator, a command to operate the power tool. In response to receiving the command, the at least one processor determines whether at least one of a value of a master authentication counter of the power tool and a value of a user authentication counter of the power tool has reached a predetermined threshold. In response to determining that the at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold, the at least one processor disables the power tool.
Claims20
A method, comprising:
- receiving, by at least one processor of a power tool and from an operator, a command to operate the power tool;
- in response to receiving the command, determining, by the at least one processor, whether at least one of a value of a master authentication counter of the power tool and a value of a user authentication counter of the power tool has reached a predetermined threshold;
- and
- in response to determining that the at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold, disabling, by the at least one processor, the power tool.
A power tool, comprising:
- a memory, configured to store a value of a master authentication counter and a value of a user authentication counter;
- and
- at least one processor configured to:
- receive, from an operator, a command to operate the power tool;
- in response to receiving the command, determine whether at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold;
- and
- in response to determining that the at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold, disable the power tool.
A system, comprising:
- a power tool, comprising:
- a memory, configured to store a value of a master authentication counter and a value of a user authentication counter;
- and
- at least one processor configured to:
- receive, from an operator, a command to operate the power tool;
- in response to receiving the command, determine whether at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold;
- and
- in response to determining that the at least one of the value of the master authentication counter and the value of the user authentication counter has reached a predetermined threshold, disable the power tool;
- a first external device configured to:
- store a master software key in a first memory;
- and
- transmit the master software key to the power tool;
- wherein the at least one processor of the power tool is further configured to:
- receive the master software key;
- validate the master software key;
- and
- in response to validating the master software key, reset the value of the master authentication counter and the value of the user authentication counter;
- and
- a second external device configured to:
- store a user software key in a second memory;
- and
- transmit the user software key to the power tool;
- wherein the at least one processor of the power tool is further configured to:
- receive the user software key;
- validate the user software key;
- and
- in response to validating the user software key, reset the value of the user authentication counter but not the value of the master authentication counter.
