Abstract

A system includes a barcode reader that is configured to use different types of rechargeable power sources and charging circuitry that is configured to provide a charging current and a charging voltage for a rechargeable power source that is being used by the barcode reader. The charging circuitry is configured to adjust the charging current and the charging voltage for the different types of rechargeable power sources that are used by the barcode reader.

First claim

What is claimed is:

1. A system, comprising:
a barcode reader that is configured to use different types of rechargeable power sources; and
charging circuitry that is configured to provide a charging current and a charging voltage for a rechargeable power source that is being used by the barcode reader, wherein the charging circuitry is configured to adjust the charging current and the charging voltage for the different types of rechargeable power sources that are used by the barcode reader.

2. The system of claim 1 , wherein:
the charging circuitry is configured to provide a first charging current and a first charging voltage if the rechargeable power source comprises a first type of rechargeable power source; and
the charging circuitry is configured to provide a second charging current and a second charging voltage if the rechargeable power source comprises a second type of rechargeable power source.

3. The system of claim 2 , wherein:
the first type of rechargeable power source comprises a rechargeable battery; and
the second type of rechargeable power source comprises a supercapacitor.

4. The system of claim 1 , wherein the charging circuitry is additionally configured to:
detect a type of rechargeable power source that is being used by the barcode reader; and
provide the charging current and the charging voltage that are appropriate for that type of rechargeable power source.

5. The system of claim 1 , wherein the charging circuitry is additionally configured to receive notification from the rechargeable power source about the charging current and the charging voltage that are appropriate for the rechargeable power source.

6. The system of claim 1 , wherein:
the barcode reader further comprises a first set of reader charging contacts corresponding to a first type of rechargeable power source and a second set of reader charging contacts corresponding to a second type of rechargeable power source;
the first type of rechargeable power source is positionable within the barcode reader such that first charging contacts on the first type of rechargeable power source are in physical contact with the first set of reader charging contacts; and
the second type of rechargeable power source is positionable within the barcode reader such that second charging contacts on the second type of rechargeable power source are in physical contact with the second set of reader charging contacts.

7. The system of claim 6 , wherein:
the charging circuitry is additionally configured to provide a first charging current and a first charging voltage to the first set of reader charging contacts; and
the charging circuitry is additionally configured to provide a second charging current and a second charging voltage to the second set of reader charging contacts.

8. The system of claim 7 , wherein:
the system further comprises a charging cradle for the barcode reader, wherein the charging cradle comprises a first set of cradle charging contacts corresponding to the first type of rechargeable power source and a second set of cradle charging contacts corresponding to the second type of rechargeable power source; and
the first set of reader charging contacts, the second set of reader charging contacts, the first set of cradle charging contacts, and the second set of cradle charging contacts are positioned such that when the barcode reader is placed in the charging cradle, the first set of reader charging contacts are in physical contact with the first set of cradle charging contacts and the second set of reader charging contacts are in physical contact with the second set of cradle charging contacts.

9. The system of claim 8 , wherein the charging circuitry is additionally configured to:
provide the first charging current and the first charging voltage to the first set of cradle charging contacts; and
provide the second charging current and the second charging voltage to the second set of cradle charging contacts.

10. The system of claim 1 , wherein:
the system further comprises a charging cradle for the barcode reader;
the charging circuitry further comprises a cradle charging coil within the charging cradle and a reader charging coil within the barcode reader; and
the cradle charging coil transfers energy to the reader charging coil via electromagnetic induction when the charging cradle is connected to an external power source and the barcode reader is placed in the charging cradle.

11. A system, comprising:
a charging cradle that is configured to charge a rechargeable power source; and
charging circuitry within the charging cradle, the charging circuitry being configured to:
provide a first charging current and a first charging voltage if the rechargeable power source corresponds to a first type of rechargeable power source; and
provide a second charging current and a second charging voltage if the rechargeable power source corresponds to a second type of rechargeable power source.

12. The system of claim 11 , wherein:
the first type of rechargeable power source comprises a rechargeable battery; and
the second type of rechargeable power source comprises a supercapacitor.

13. The system of claim 11 , wherein the charging circuitry is additionally configured to detect whether the rechargeable power source corresponds to the first type of rechargeable power source or the second type of rechargeable power source.

14. The system of claim 11 , wherein the charging circuitry is additionally configured to receive notification from the rechargeable power source about a charging current and a charging voltage that are appropriate for the rechargeable power source.

15. The system of claim 11 , wherein:
the charging cradle comprises a first set of cradle charging contacts corresponding to the first type of rechargeable power source and a second set of cradle charging contacts corresponding to the second type of rechargeable power source;
the first type of rechargeable power source is positionable within the charging cradle such that first charging contacts on the first type of rechargeable power source are in physical contact with the first set of cradle charging contacts; and
the second type of rechargeable power source is positionable within the charging cradle such that second charging contacts on the second type of rechargeable power source are in physical contact with the second set of cradle charging contacts.

16. The system of claim 15 , wherein the charging circuitry is additionally configured to:
provide the first charging current and the first charging voltage to the first set of cradle charging contacts; and
provide the second charging current and the second charging voltage to the second set of cradle charging contacts.

17. A system, comprising:
a barcode reader that is configured to use different types of rechargeable power sources; and
charging circuitry that is configured to:
provide a first charging current and a first charging voltage if a rechargeable power source that is being used by the barcode reader corresponds to a first type of rechargeable power source; and
provide a second charging current and a second charging voltage if the rechargeable power source that is being used by the barcode reader corresponds to a second type of rechargeable power source.

18. The system of claim 17 , wherein the charging circuitry is additionally configured to detect whether the rechargeable power source that is being used by the barcode reader corresponds to the first type of rechargeable power source or the second type of rechargeable po
