Abstract

A method of controlling a power system includes receiving a signal indicative of user interaction with a handle of a removable battery, and switching a power interface of the power system from a first power sourcing mode receiving power from the removable battery to a second power sourcing mode receiving power from a back-up battery. An electronic control unit for the power system includes a memory storing computer executable instructions for controlling power sourcing in the power control system, a detector interface configured to receive a signal indicative of user interaction with a removable battery of the mobile workstation and a microprocessor configured by way of executing the computer executable instructions to switch a power interface of the power control system from a first power sourcing mode to a second power sourcing mode.

Claims

1. A method of controlling a power system of a mobile workstation comprising the steps of:

receiving a signal indicative of user interaction with a first one of two batteries coupled with the power system, the first one of the two batteries including a removable battery supplying power to a computerized device of the mobile workstation;

switching a power interface of the power system from a first power sourcing mode receiving power from the removable battery to a second power sourcing mode receiving power from a second battery resident on the mobile workstation, responsive to the signal, and such that the second battery supplies power to the computerized device when the removable battery is decoupled from the power system by way of the user interaction; and

operating the power interface in a third mode in which the second battery is charged via a replacement battery coupled with the power system in place of the removable battery;

wherein the switching step includes switching the power interface while the removable battery is electrically connected with the power interface; and

wherein the receiving step includes receiving the signal from a sensor resident on a battery assembly which includes the removable battery such that upon decoupling the removable battery the sensor is decoupled from the mobile workstation.

2. The method of claim 1 wherein the receiving step comprises receiving a user proximity signal from a proximity sensor.

3. The method of claim 1 further comprising a step of switching the power interface from the second power sourcing mode back to the first power sourcing mode in response to electrically connecting the replacement battery with the power interface in place of the removable battery.

4. The method of claim 1 further comprising a step of activating a countdown timer in response to switching the power interface from the first power sourcing mode to the second power sourcing mode.

5. The method of claim 4 further comprising a step of outputting a shutdown signal to the power system in response to expiration of the countdown timer.

6. A power control system for a mobile workstation comprising:

a power interface having a first input interface configured to connect with a first battery, a second input interface configured to connect with a second battery and an output interface configured to receive power from either of the first and second input interfaces for powering a computerized device of the mobile workstation;

a detector interface configured to receive a user interaction signal indicative of expected decoupling of the first battery from the power interface; and

a microprocessor coupled with the detector interface and in control communication with the power interface, the microprocessor being configured to switch the power interface from a first power sourcing mode receiving power via the first input interface to a second power sourcing mode receiving power via the second input interface, responsive to the user interaction signal;

the microprocessor being further configured to operate the power interface in a third mode in which the second battery is charged via a third battery swapped with the first battery.

7. The power control system of claim 6 wherein the detector interface comprises a sensor interface configured to receive a user interaction signal from a sensor resident on a battery assembly which includes the first battery.

8. The power control system of claim 7 wherein the second power sourcing mode comprises a back-up mode, and wherein the microprocessor is configured to switch the power interface to the back-up mode to receive power via the second input interface from a back-up battery, responsive to the user interaction signal.

9. The power control system of claim 8 wherein the power interface comprises a solid state electronic switch having a first state corresponding to the first power sourcing mode and electrically connecting the output interface with the first input interface but not the second input interface, and a second state corresponding to the second power sourcing mode.

10. The power control system of claim 8 further comprising a display controllably coupled with the microprocessor and having a plurality of display states which are based at least in part on the power sourcing mode of the power interface.

11. The power control system of claim 9 wherein the first input interface is electrically connected with the second input interface in the third mode.

12. The power control system of claim 9 further comprising a countdown timer coupled with the microprocessor, wherein the microprocessor is configured to output a start signal to activate the countdown timer in response to the user interaction signal.

13. The power control system of claim 12 wherein the microprocessor is further configured to output a shutdown signal to the power system in response to expiration of the countdown timer.

14. The power control system of claim 7 further comprising a rewritable memory storing computer executable instructions for controlling power sourcing in the power control system, a programming interface and a memory writing device configured to overwrite the computer executable instructions based on inputs from the programming interface.

15. An electronic control module for a power control system of a mobile workstation comprising:

a computer readable memory storing computer executable instructions for controlling power sourcing in the power control system;

a detector interface configured to receive a user interaction signal indicative of expected decoupling of a first one of two batteries from the mobile workstation; and

a microprocessor coupled with the computer readable memory and with the detector interface, the microprocessor being configured by way of executing the computer executable instructions to switch a power interface of the power control system from a first power sourcing mode receiving power from the first one of the two batteries via a first input interface to a second power sourcing mode receiving power from a second one of the two batteries via a second input interface, responsive to the signal, and while the first one of the batteries is coupled with the mobile workstation;

the microprocessor being further configured by way of executing the computer executable instructions to operate the power interface in a third mode in which the second battery is charged via a third battery swapped with the first battery.

16. The electronic control module of claim 15 wherein the microprocessor is configured to switch the power system from the first power sourcing mode receiving power from the removable battery to the second power sourcing mode receiving power from a back-up battery resident on the mobile workstation, in response to the signal.

17. The electronic control module of claim 16 wherein the computer readable memory comprises a computer rewritable memory.
