TOOL LOCK
First Claim
1. A method in a power tool for enabling unlocking and locking of a power tool for prevention of unauthorized use, the method comprising:
- receiving a message to a control unit, the message including an instruction to unlock the power tool,unlocking the power tool according to the instruction by the control unit via an actuator unit, thereby enabling prevention of unauthorized use of the power tool by remote unlocking,counting an authorization time period from a reception of the first unlock message to the control unit by a counter,when a second unlock message is received before the predetermined threshold of an authorization time period is reached the counter is restarted, such that the power tool remains unlocked,a position message including an alert signal is received by the control unit, the position message including an instruction to repeatedly transmit a response signal as a response to the alert signal, thereby enabling positioning of the tool, andwhen the predetermined threshold of the counted authorization time period is reached, locking the power tool according to the instruction by the control unit via the actuator unit.
