Abstract

A power tool includes a motor and a controller in a power tool housing. A battery pack interface is defined on and/or in the power tool housing. A receptacle is defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing. At least one communication terminal is disposed within the receptacle and is electrically connectable to the wireless communication adapter. The controller outputs to the at least one communication terminal a signal indicating a charge level of a battery pack attached to the battery pack interface, a number of hours of operation of the power tool, a power tool overheated alert, and/or a battery pack overloaded alert.

First claim

The invention claimed is:

1. A power tool comprising:
a motor;
a controller;
a power tool housing accommodating the motor and the controller,
a battery pack interface defined on and/or in the power tool housing and electrically connected to the motor and the controller;
a receptacle defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing, and
at least one communication terminal disposed within the receptacle and configured to be electrically connected to at least one communication terminal on the wireless communication adapter to establish a data communication path with the controller so that the wireless communication adapter accesses data stored in the controller,
wherein the controller is configured to output to the at least one communication terminal disposed within the receptacle at least one signal selected from the group consisting of:
a charge level of a battery pack attached to the battery pack interface,
a number of hours of operation of the power tool,
a power tool overheated alert, and/or
a battery pack overloaded alert.

2. The power tool according to claim 1 , wherein the controller is configured to change an operating parameter of the power tool in response to receiving an operating parameter signal via the at least one communication terminal.

3. The power tool according to claim 1 , wherein the controller is configured to output a serial number of the power tool to the at least one communication terminal.

4. The power tool according to claim 1 , further comprising means for detachably connecting the wireless communication adapter to the power tool housing.

5. The power tool according to claim 4 , wherein the means for detachably connecting the wireless communication adapter to the power tool housing includes one of a rib that engages in a slot defined in the receptacle or one or more slide rails.

6. The power tool according to claim 1 , wherein the controller is configured to output to the at least one communication terminal disposed within the receptacle all of the following signals:
a charge level of a battery pack attached to the battery pack interface,
a number of hours of operation of the power tool,
a power tool overheated alert, and
a battery pack overloaded alert.

7. The power tool according to claim 6 , wherein the controller is configured to change an operating parameter of the power tool in response to receiving an operating parameter signal via the at least one communication terminal.

8. The power tool according to claim 7 , wherein the controller is configured to output a serial number of the power tool to the at least one communication terminal.

9. The power tool according to claim 8 , further comprising means for detachably connecting the wireless communication adapter to the power tool housing.

10. The power tool according to claim 9 , wherein the means for detachably connecting the wireless communication adapter to the power tool housing includes one of a rib that engages in a slot defined in the receptacle or one or more slide rails.

11. The power tool according to claim 1 , wherein a slot is defined in the receptacle and is configured to receive a rib formed on the wireless communication adapter.

12. The power tool according to claim 1 , further comprising:
at least one power terminal disposed within the receptable and configured to conduct current from the battery pack interface to at least one power terminal on the wireless communication adapter.

13. The power tool according to claim 1 , wherein the receptacle is configured to receive the wireless communication adapter, which has a self-contained power supply.

14. The power tool according to claim 13 , wherein the self-contained power supply is a battery disposed in the wireless communication adapter.

15. The power tool according to claim 14 , further comprising:
at least one power terminal disposed within the receptable and configured to conduct current from the battery pack interface to at least one power terminal on the wireless communication adapter.

16. The power tool according to claim 1 , further comprising the wireless communication adapter, wherein the wireless communication adapter has a self-contained power supply.

17. The power tool according to claim 16 , wherein the self-contained power supply is a battery disposed within the wireless communication adapter.

18. The power tool according to claim 17 , wherein the controller is configured to output the charge level of the battery pack attached to the battery pack interface to the at least one communication terminal disposed within the receptacle.

19. The power tool according to claim 18 , wherein the controller is configured to output the power tool overheated alert and the battery pack overloaded alert to the at least one communication terminal disposed within the receptacle.

20. The power tool according to claim 19 , further comprising:
at least one power terminal disposed within the receptable and configured to conduct current from the battery pack interface to at least one power terminal on the wireless communication adapter.
