Abstract

The present invention relates to a device for recharging a battery of a portable ionizing-radiation sensor resting on a recharging base. The sensor includes, on one or more accessible faces, a plurality of electrical-contact areas connected to the battery that powers the sensor. The recharging base comprises a device for mobilizing one or more mobile contacts. The mobile contacts are connected to a power source. The mobile contacts mechanically enter the body (i.e., housing) of the recharging base and mechanically protrude from the body of the recharging base through one or more openings made in the body of the recharging base. The mobile contacts are electrically in contact with the plurality of electrical-contact areas of the sensor if one or more of the plurality of electrical-contact areas are positioned facing the openings when the mobile contacts protrude from the recharging base. An embodiment of the invention may be used for X-ray or Gamma-ray medical imaging.

Claims

1. A device for recharging a battery of a battery-powered portable ionizing-radiation sensor having a sensor and a recharging base to recharge the sensor, the sensor being rested on the recharging base, wherein:

the sensor comprises;

one or more accessible faces;

a plurality of electrical-contact areas on the one or more accessible faces, the plurality of electrical-contact areas connected to the battery that powers the sensor; and

the recharging base comprises;

a housing having one or more openings; and

one or more mobile contacts connected to a power source, wherein the one or more mobile contacts protrude from the housing through at least one of the one or more openings in the housing,

wherein the one or more mobile contacts are electrically in contact with at least a portion of the plurality of electrical-contact areas of the sensor if one or more of the plurality of electrical-contact areas are positioned facing the one or more openings of the housing when the mobile contacts protrude from the recharging base.

2. The device according to claim 1, wherein the plurality of electrical-contact areas contact the mobile contacts of the recharging base when the one or more accessible faces of the sensor are positioned facing the recharging base in one or more predefined positions.

3. The device according to claim 1, wherein the recharging base comprises a door, the door configurable into a closed position that closes the one or more openings, and the door further configurable into an open position that uncovers the one or more openings.

4. The device according to claim 3, wherein the door is in the open position when the mobile contacts protrude from the body and the door is in the closed position when the mobile contacts are retracted inside the housing by use of a mechanism that moves both the door and the mobile contacts.

5. The device according to claim 1, wherein each electrical-contact area has a polarity that is dependent on its position on the one or more accessible faces of the sensor, the polarity of each electrical-contact area corresponding to the polarity of a mobile contact that lies opposite said electrical-contact area when the sensor is positioned in predetermined position.

6. The device according to claim 1, wherein the plurality of electrical-contact areas are affixed to a removable electrical-contact-area plate, and the removable electrical-contact-area plate is affixed to the sensor.

7. The device according to claim 1, wherein at least one of said one or more mobile contacts of the recharging base is removable.

8. The device according to claim 1, wherein at least one of said one or more mobile contacts comprises a spring.

9. The device according to claim 1, wherein the sensor is placed on a support to which the recharging base is affixed, the one or more openings in the recharging base facing one or more openings in the support.

10. The device according to claim 1, further comprising a switch for selectively applying power to the mobile contacts.

11. A recharging base for recharging a battery of a portable device when the portable device is resting on the recharging base, wherein the recharging base comprises:

a housing having one or more openings; and

one or more mobile contacts connected to a power source, wherein the one or more mobile contacts protrude from the housing through at least one of the one or more openings in the housing,

wherein the one or more mobile contacts are electrically in contact with at least a portion of a plurality of electrical-contact areas of the portable device if one or more of the plurality of electrical-contact areas are positioned facing the one or more openings of the housing when the mobile contacts protrude from the recharging base.

12. The device according to claim 11, wherein a plurality of electrical-contact areas of the portable device contact the mobile contacts of the recharging base when the plurality of electrical-contact areas of the portable device face the recharging base in one or more predefined positions.

13. The device according to claim 11, wherein the recharging base comprises a door, the door configurable into a closed position that closes the one or more openings, and the door further configurable into an open position that uncovers the one or more openings.

14. The device according to claim 13, wherein the door is in the open position when the mobile contacts protrude from the body and the door is in the closed position when the mobile contacts are retracted inside the housing by use of a mechanism that moves both the door and the mobile contacts.

15. The device according to claim 11, wherein at least one of said one or more mobile contacts of the recharging base is removable.

16. The device according to claim 11, wherein at least one of said one or more mobile contacts comprises a spring.

17. The device according to claim 11, further comprising a support to which the recharging base is affixed, the one or more openings in the recharging base facing one or more openings in the support, wherein the portable device is placed on the support.

18. The device according to claim 11, further comprising a switch for selectively applying power to the mobile contacts.
