Abstract
A cutoff system for a power tool or other device includes a receiver and a transmitter, the receiver being configured to electrically couple to a power source and to a power tool or other device, the transmitter is configured to transmit a communication signal to the receiver, and the receiver is further configured to transmit electrical power from the power source to the power tool or other device only when the receiver receives the communication signal from the transmitter.
Claims14
A detachable adapter configured to automatically cut off power to an electrical power tool, the detachable adapter having a first location to selectively attach to the electrical power tool and a second location to selectively attach to a removable battery, the detachable adapter comprising:
- a receiver mounted within the adapter configured to:
- (i) receive a first communication signal broadcast by a transmitter;
- (ii) to command the detachable adapter to transmit electrical current from the battery to the electrical power tool when the receiver detects the first communication signal;
- and (iii) to interrupt electrical current from the battery to the electrical power tool when the receiver does not detect the first communication signal,
- wherein the transmitter comprises a body and an arm, a first electrical contact located on the arm, and a second electrical contact located on the body of the transmitter, wherein the transmitter is configured to broadcast the first communication signal only when the first and second electrical contacts are not engaged with one another.
A detachable adapter configured to automatically cut off power to an electrically operated device, the detachable adapter having a first location to selectively attach to the electrically operated device and a second location to selectively attach to a removable battery, the detachable adapter comprising:
- a receiver mounted within the adapter configured to:
- (i) receive a first communication signal broadcast by a transmitter;
- (ii) to command the detachable adapter to transmit electrical current from the battery to the electrically operated device when the receiver detects the first communication signal;
- and (iii) to interrupt electrical current from the battery to the electrically operated device when the receiver does not detect the first communication signal,
- wherein the transmitter comprises a body and an arm, a first electrical contact located on the arm, and a second electrical contact located on the body of the transmitter, wherein the transmitter is configured to broadcast the first communication signal only when the first and second electrical contacts are not engaged with one another.
