Abstract

A printed circuit (PC) card apparatus can, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) PC card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe PC card. The PCIe card includes a primary battery to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card. The PC card apparatus also includes a PCIe edge connector protector enclosing electrically conductive fingers of a PCIe edge card connector. The PCIe edge connector protector includes a hidden supplemental charge storage device integrated into the PCIe edge connector protector. The PCIe edge connector protector also includes electrically conductive contacts to transfer supplemental power from the supplemental charge storage device to the electronic security device.

First claim

What is claimed is:

1. A printed circuit (PC) card apparatus configured to, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe card, the PC card apparatus comprising:
the PCIe card, the PCIe card including:
a primary battery configured to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card; and
a PCIe edge card connector; and

a PCIe edge connector protector enclosing electrically conductive fingers of the PCIe edge card connector, the PCIe edge connector protector including:
a supplemental charge storage device that is hidden from view and that is integrated into the PCIe edge connector protector;
electrically conductive contacts configured to transfer supplemental power from the supplemental charge storage device to the electronic security device by completing, through contacting corresponding electrically conductive fingers of the PCIe edge connector, an electrical circuit between the supplemental charge storage device and the security device.

2. The PC card apparatus of claim 1 , wherein the supplemental charge storage device is selected from the group consisting of: a nickel metal hydride (NiMH) battery, a lithium-ion (Li-ion) battery, an alkaline battery, and a supercapacitor.

3. The PC card apparatus of claim 1 , wherein the supplemental charge storage device has a charge storage capacity of at least 1,500 mAh.

4. The PC card apparatus of claim 1 , wherein the charge storage capacity of the supplemental charge storage device, in conjunction with charge storage capacity of the primary battery, is sufficient to supply electrical power to enable operation, in the absence of externally supplied power, of the security device for a time interval of at least five years.

5. A printed circuit (PC) card apparatus configured to, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe card, the PC card apparatus comprising:
the PCIe card, the PCIe card including:
a primary battery configured to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card; and
a PCIe edge card connector; and

a motherboard connector attached to a motherboard and enclosing electrically conductive fingers of the PCIe edge card connector, the motherboard connector including:
a supplemental charge storage device that is hidden from view and that is integrated into the motherboard connector;
electrically conductive contacts configured to transfer supplemental power from the supplemental charge storage device to the electronic security device by completing, through contacting corresponding electrically conductive fingers of the PCIe edge connector, an electrical circuit between the supplemental charge storage device and the security device.

6. The PC card apparatus of claim 5 , wherein the supplemental charge storage device is selected from the group consisting of: a nickel metal hydride (NiMH) battery, a lithium-ion (Li-ion) battery, an alkaline battery, and a supercapacitor.

7. The PC card apparatus of claim 5 , wherein the supplemental charge storage device has a charge storage capacity of at least 1,500 mAh.

8. The PC card apparatus of claim 5 , wherein the charge storage capacity of the supplemental charge storage device, in conjunction with charge storage capacity of the primary battery, is sufficient to supply electrical power to enable operation, in the absence of externally supplied power, of the security device for a time interval of at least five years.

9. A printed circuit (PC) card apparatus configured to, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe card, the PC card apparatus comprising:
the PCIe card, inserted into a stacking connector, the PCIe card including:
a primary battery configured to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card; and
a PCIe edge card connector; and

the stacking connector, inserted into a motherboard connector attached to a motherboard and enclosing electrically conductive fingers of the PCIe edge card connector, the stacking connector including:
a supplemental charge storage device that is hidden from view and that is integrated into the stacking connector;
electrically conductive contacts configured to transfer supplemental power from the supplemental charge storage device to the electronic security device by completing, through contacting corresponding electrically conductive fingers of the PCIe edge connector, an electrical circuit between the supplemental charge storage device and the security device.

10. The PC card apparatus of claim 9 , wherein the supplemental charge storage device is selected from the group consisting of: a nickel metal hydride (NiMH) battery, a lithium-ion (Li-ion) battery, an alkaline battery, and a supercapacitor.

11. The PC card apparatus of claim 9 , wherein the supplemental charge storage device has a charge storage capacity of at least 1,500 mAh.

12. The PC card apparatus of claim 9 , wherein the charge storage capacity of the supplemental charge storage device, in conjunction with charge storage capacity of the primary battery, is sufficient to supply electrical power to enable operation, in the absence of externally supplied power, of the security device for a time interval of at least five years.
