Abstract

A medical monitor is disclosed for implantation in a human body for monitoring biological activity and states as detected by implanted sensors. The medical monitor includes a primary disk drive and a secondary disk drive, where the secondary disk drive mirrors the primary disk drive. An enclosure surrounds at least one of the primary and secondary drives. A transmitter and receiver for produces and transmits signals. The medical monitor is in communication with the sensors, by which information on biological activity and states is stored on the primary disk drive, and the secondary disk drive.

Claims

1. A medical monitor for implantation in the user'"'"'s body for monitoring data on biological activity and states gathered from sensors implanted in the user'"'"'s body, said medical monitor comprising:

a primary disk drive and a secondary disk drive, wherein said secondary disk drive mirrors said primary disk drive;

an enclosure surrounding at least one of said primary and said secondary drives; and

a transmitter and receiver for producing and transmitting signals, said medical monitor being in communication with said sensors, by which information on biological activity and states is stored on said primary and secondary disk drives.

2. The medical monitor of claim 1, wherein:

both said primary drive and said secondary drive are located within said enclosure which is implanted with the body of a user.

3. The medical monitor of claim 1, wherein:

said primary drive is located within said enclosure which is implanted with the body of a user and said secondary drive is located outside of the body of the user, wherein said primary and secondary drives are in radio contact so that said secondary drive mirrors said primary drive.

4. The medical monitor of claim 3, further comprising:

an alert mechanism which signals the user that a back-up to the secondary hard disk drive is scheduled to be performed.

5. The medical monitor of claim 4, wherein:

said alert mechanism includes a piezo micro-speaker.

6. The medical monitor of claim 4, wherein:

said alert mechanism includes a vibration motor.

7. The medical monitor of claim 4, wherein:

said alert mechanism is a local alert.

8. The medical monitor of claim 4, wherein:

said alert mechanism is a remote alert.

9. The medical monitor of claim 1, wherein:

said primary drive and a secondary drive are in communication with each other, to provide disk drive data redundancy and data backup; and

said disk drive data redundancy and data backup is accomplished by an operating configuration chosen from the group consisting of RAID 0, RAID 1, or RAID 0+1 techniques.

10. The medical monitor of claim 1, further comprising:

a recharging system including at least one rechargeable battery and an induction electronics interface.

11. The medical monitor of claim 1, wherein:

transmissions are encrypted as encrypted information for security of the user.

12. The medical monitor of claim 1, wherein:

said enclosure includes sound-proofing materials.

13. The medical monitor of claim 1, further comprising:

a GPS transmitter and a receiver for producing and receiving transmission signals in the radio frequency range, said a GPS transmitter for sending satellite communication signals via the public GPS frequencies and protocol.

14. The medical monitor of claim 1, wherein:

said enclosure includes a shock-proofing system.

15. The medical monitor of claim 1, further comprising:

an electrical grounding structure which diverts high voltage or current spikes from said at least one disk drive.

16. The medical monitor of claim 1, further comprising:

an alert mechanism which is used to signal the user of medical and maintenance conditions.

17. A system for monitoring biological activity and states in the body of a user, comprising:

a medical HDD monitor, including a primary drive and a secondary drive, wherein said secondary drive mirrors said primary drive, and a transmitter and a receiver for producing and transmitting signals in the radio frequency range;

at least one sensor for communicating data from at least one site in said body of said user to said medical HDD monitor; and

an external programming interface which communicates with said medical HDD monitor by radio frequency transmission, in order to set performance parameters of said medical HDD monitor.

18. The system claim 17, further comprising:

an external programming device which is in radio frequency communication with said medical HDD monitor.

19. The system of claim 18, wherein:

said external programming device is chosen from a group consisting of hand-held computers and laptop computers.

20. The system of claim 17, wherein:

said at least one hard disk drive includes two disk drives, which are in communication with each other, to provide disk drive data redundancy and data backup; and

said disk drive data redundancy and data backup is accomplished by an operating configuration chosen from the group consisting of RAID 0, RAID 1, or RAID 0+1 techniques.
