Referring now to FIGS. 1-3, one illustrative embodiment of an adapter 10 for transferring electric signals to and/or from a pneumatic tool 12 is shown. The adapter 10 includes a tool interface 20 and a charger interface 22. In the illustrative embodiment, the tool interface 20 of the adapter 10 is configured to receive a portion of the pneumatic tool 12, as shown in FIG. 2. It is contemplated that, in other embodiments, the adapter 10 may be used with any type of non-electrically powered tool. The charger interface 22 of the adapter 10 is configured to be received by a charger unit 14, as shown in FIG. 2. The charger unit 14 may be any device that is designed for charging a battery (e.g., a battery that is used to energize an electric motor of an electrically powered tool). By way of example, the charger unit 14 may be illustratively embodied as an Ingersoll-Rand IQV20 Series Lithium-Ion Battery Charger, commercially available from Ingersoll-Rand Company of Davidson, N.C. It will be appreciated that the adapter 10 may be configured to be used with any suitable charger unit 14.
The pneumatic tool 12 includes a pneumatic motor (not shown) that is energized by a pressurized fluid (e.g., by connecting the pneumatic tool to a source of compressed air via a hose). Additionally, the pneumatic tool 12 includes electronics 16 for enhancing the performance of the pneumatic tool 12. By way of example, the electronics 16 may control an output speed or an output torque of the pneumatic tool 12. In the illustrative embodiment, the electronics 16 monitor usage (e.g., output speed, output torque, operating time, and the like) of the pneumatic tool 12.
In the illustrative embodiment, the electronics 16 of the pneumatic tool 12 include a monitoring circuit 17 and a rechargeable power storage 18. The monitoring circuit 17 may include one or more sensors that monitor one or more components of the pneumatic tool 12. The monitoring circuit 17 may also include a processor and/or a memory device for analyzing and/or storing data relating to usage of the pneumatic tool 12 (e.g., information from the one or more sensors of the monitoring circuit 17). The rechargeable power storage 18 of the electronics 16 supplies power to the monitoring circuit 17. The rechargeable power storage 18 may be embodied as a battery, a capacitor, or any other type of power storage device.

As the motor of pneumatic tool 12 is energized by a pressurized fluid and not by electricity, the pneumatic tool 12 does not have a battery or a direction connection to mains electricity (like an electrically powered tool) that might also be used for charging the rechargeable power storage 18. Instead, the adapter 10 supplies a power signal to the electronics 16 that is used to charge the rechargeable power storage 18. As described further below, the adapter 10 receives a power signal from the charger unit 14 and (after manipulation, in some embodiments) supplies the power signal to the electronics 16 of the pneumatic tool 12. Depending on the electronics 16 of the pneumatic tool 12, the power signal supplied by the adapter may be an alternating current (AC) power signal or a direct current (DC) power signal.
In some embodiments, the adapter 10 may also receive data signals from the electronics 16 of the pneumatic tool 12 (e.g., from the monitoring circuit 17). By way of example, these data signals may contain data associated with the usage of the pneumatic tool 12. For instance, the data signals may contain data relating to at least one of an operating time the pneumatic tool 12, an output speed of the pneumatic tool 12, and an output torque of the pneumatic tool 12. The data signals may contain data related to a single usage session of the pneumatic tool 12, usage of the pneumatic tool 12 over a specific time period, or usage over the entire life of the pneumatic tool 12.
In some embodiments, the adapter 10 may also transmit data signals to the electronics 16 of the pneumatic tool 12 (e.g., to the monitoring circuit 17). By way of example, these data signals may contain data relating to software and/or firmware used by the electronics 16 of the pneumatic tool 12. For instance, the data signals may include a software or firmware update for the electronics 16 included in pneumatic tool 12.
As shown in FIG. 3, the adapter 10 includes a tool connector 34, a charger connector 36, and an adapter circuit 38. The tool connector 34 is configured to interface with the electronics 16 of the pneumatic tool 12 and to communicate electric signals between the electronics 16 of the pneumatic tool 12 and the adapter circuit 38. The charger connector 36 is configured to interface with the charger unit 14 and communicate electric signals between the charger unit 14 and the adapter circuit 38. The adapter circuit 38 is coupled to both the tool connector 34 and the charger connector 36.
In the illustrative embodiment, a housing 32 encloses the tool connector 34, charger connector 36, and adapter circuit 38. The housing 32 may be made from a variety of materials. In the illustrative embodiment, the housing 32 is made from plastic. As mentioned above, the housing 32 generally includes the tool interface 20 and the charger interface 22. In the illustrative embodiment, the tool interface 20 and the charger interface 22 are located on opposite sides of the housing 32. It will be appreciated that, in other embodiments, other configurations for the tool interface 20 and the charger interface 22 are possible.
In the illustrative embodiment, the tool interface 20 is formed to receive a portion of the pneumatic tool 12. In particular, a tool-receiving cavity 48 that is sized to receive an end portion of the pneumatic tool 12 is defined in the tool interface 20. The tool-receiving cavity 48 may be sized to receive a portion of a specific pneumatic tool, a specific category of pneumatic tools, or a variety of pneumatic tools. In some embodiments, the tool interface 20 may be configured to be removably coupled to the pneumatic tool 12.
The charger interface 22 is formed to be received by the charger unit 14. In some embodiments, the charger interface 22 is configured to be removably coupled to the charger unit 14. The charger interface 22 may be formed to be received by a specific charger unit 14, a specific category of charger units 14, or a variety of charger units 14. In the illustrative embodiment, the charger interface 22 includes a battery-terminal rail 50 sized to be received by a battery-terminal slot 52 of the charger unit 14.
In some embodiments, such as that shown in FIGS. 1-3, the housing 32 includes a charger unit lock 54. The charger unit lock 54 includes a latch 56 and a release 58.

When the charger unit lock 54 is moved to the unlocked position, the latch 56 uncouples from the charger unit 14 and the adapter 10 may be removed from the charger unit 14. In the illustrative embodiment, the charger unit lock 54 automatically assumes the locked position when the adapter 10 is removably coupled to the charger unit 14. The charger unit lock 54 is moved to the unlocked position when a sufficient force is applied to the release 58.
Referring now to FIGS. 3 and 4, the tool connector 34 may be any device(s) capable of communicating a power signal and/or a data signal between the electronics 16 of the pneumatic tool 12 and the adapter circuit 38. In the illustrative embodiment, the tool connector 34 is a Universal Serial Bus (USB) connector configured to communicate both a power signal and a data signal between the electronics 16 of the pneumatic tool 12 and the adapter circuit 38. In other embodiments, the tool connector 34 may communicate only a power signal or only a data signal between the electronics 16 of the pneumatic tool 12 and the adapter circuit 38. In the illustrative embodiment, the tool connector 34 is disposed at the tool interface 20.
The charger connector 36 may be any device(s) capable of communicating a power signal between the charger unit 14 and the adapter circuit 38. In the illustrative embodiment, the charger connector 36 is formed by battery terminals 40.

The charger unit 14 is configured to receive power from an external source (e.g., mains electricity). The charger unit 14 produces a power signal from the power received from the external source. When the adapter 10 is removably coupled to the charger unit 14, this power signal is transferred through the charger unit terminals 42 to the adapter circuit 38 via the battery terminals 40.
In some embodiments, the adapter 10 may also include a data connector 60, as shown in FIG. 4. The data connector 60 may be coupled to the adapter circuit 38 and configured to communicate the data signals between the adapter circuit 38 and one or more computing devices. By way of example, the data connector 60 may be a USB connector. It will be appreciated that the data connector 60 may be any device(s) capable of communicating a data signal between the adapter circuit 38 and a computing device.
In the illustrative embodiment, the adapter circuit 38 includes a data transfer circuit 66 and a charge transfer circuit 68, as shown in FIG. 4.

The charge transfer circuit 68 is configured to communicate power signals between the charger unit 14 and the electronics 16 of the pneumatic tool 12 (via the tool connector 34 and the charger connector 36).
In some embodiments, the data transfer circuit 66 may include a memory device 70. The memory device 70 may be configured to store data associated with the data signals received from the electronics 16 of the pneumatic tool 12 and/or from a computing device. The data stored in the memory device 70 may be communicated to the electronics 16 of the pneumatic tool 12 via the tool connector 34 (in the form of one or more data signals). In some embodiments, the data stored by the memory device 70 may be communicated to one or more computing devices via the data connector 60 (in the form of one or more data signals).
In some embodiments, the data transfer circuit 66 may include a wireless network interface 72. The wireless network interface 72 may be configured to communicate data signals between the adapter 10 (specifically, the adapter circuit 38) and one or more computing devices via a wireless data link. In the illustrative embodiment, data signals produced by the electronics 16 of the pneumatic tool 12 are communicated to the data transfer circuit 66 via the tool connector 34. These data signals are then communicated to one or more computing devices via the wireless network interface 72. Likewise, data signals produced by one or more computing devices are communicated to the data transfer circuit 66 via the wireless network interface 72 and are then communicated to the electronics 16 of the pneumatic tool 12 via the tool connector 34. It is contemplated that, in some embodiments, the wireless network interface 72 may also be used to communicate data signals between the adapter 10 and the electronics 16 of the pneumatic tool 12 (rather than the tool connector 34).
In some embodiments, the charge transfer circuit 68 may include an inverter 74 that is configured to convert a DC power signal received from the charger unit 14 into an AC power signal to be supplied to the electronics 16 of the pneumatic tool 12. The inverter 74 may be any device(s) capable of converting a DC power signal into an AC power signal. It is also contemplated that, in other embodiments, the charge transfer circuit 68 may include a rectifier that is configured to convert an AC power signal received from the charger unit 14 into a DC power signal to be supplied to the electronics 16 of the pneumatic tool 12.
In some embodiments, the charge transfer circuit 68 may include a transformer 76 that is configured to change the magnitude, or amplitude, of a power signal. By way of example, where the power signal received from the charger unit 14 is larger in magnitude than the power signal to be supplied to the electronics 16 of the pneumatic tool 12 (e.g., to the rechargeable power storage 18), the transformer 76 may receive change the magnitude of the power signal. The transformer 76 may be any device(s) capable of changing the magnitude of a power signal.
In some embodiments, the adapter 10 may include an indicator 92 that represents a status of the rechargeable power storage 18 included in the electronics 16 of the pneumatic tool 12. In such embodiments, the charge transfer circuit 68 may be configured to detect the status (e.g., the charge level) of the rechargeable power storage 18 via the tool connector 34. The charge transfer circuit 68 may then communicate the status of the rechargeable power storage 18 via the indicator 92. In some embodiments, the indicator 92 may also be configured to indicate when the rechargeable power storage 18 is non-functional.
In the illustrative embodiment shown in FIGS. 1-3, the indicator 92 is a visual indicator 92 including a number of lights.
