Abstract

A personal data storage device for storing information and a system for storing and reading such information from the storage device. A programmable memory is encapsulated in a potting compound which includes a plurality of channels enclosing leads of the memory package. The channels extend to the outside of the encapsulated memory to permit exterior contact with the memory leads. A conductive sealant placed in the channels for sealing the channels of the encapsulated flash memory makes electrical contact with the leads. A device for reading the information from the data storage device includes a PCMCIA interface which can read and write data to and from the personal data storage device and a computer. The computer further includes programming for compressing and decompressing data which is stored and read from the personal data storage device.

Claims

1. A personal data storage device carried by an individual for storing information comprising:

a memory having a plurality of extending leads and which is encapsulated by an encapsulating compound having a high flexural modulus forming an environmentally secure enclosure for said memory, said encapsulating compound including a plurality of channels for enclosing said leads and which extend to the outside of said encapsulated memory forming a contact pattern to permit exterior contact with said leads; and

a conductive sealant placed in said channels for sealing said channels of said encapsulated memory against moisture and extreme environmental conditions, forming a continuous surface with said encapsulating compound and for making electrical contact with said leads, providing external contacts for said memory which are identical with a contact pattern of an interface device with transfers data from said storage device.

2. The personal storage device of claim 1, wherein said personal data storage device includes a through hole in said encapsulating compound for securing said device.

3. The personal data storage device of claim 1, wherein said conductive sealant is a conductive epoxy resin.

4. The personal data storage device of claim 1, wherein said encapsulating compound is a urethane resin.

5. The personal data storage device of claim 1, wherein said encapsulating compound forming an enclosure for said memory includes along a peripheral edge a sealed hole for receiving a necklace worn by a user of said device.

6. A personal data storage device carried by an individual comprising:

a memory having a plurality of exterior contacts;

an encapsulating urethane resin compound having a high flexural modulus enclosing said memory forming an environmentally secure enclosure, said encapsulating compound including a plurality of channels which communicate with said exterior contacts forming a contact pattern; and

a conductive sealant filling said channels forming a sealed surface with said encapsulating compound, making an electrical connection with said contacts as well as sealing said memory and its exterior contacts against moisture and extreme environmental conditions, said conductive sealant forming external contacts identical with a contact pattern of an interface device which transfers data from said memory.

7. The personal storage device according to claim 6 wherein said conductive sealant forms with said encapsulating compound a continuous surface.

8. The personal data storage device according to claim 6 wherein said external contacts are adapted to mate with an interface which includes a plurality of spring biased contacts which connect to a computer.

9. The personal data storage device of claim 6 wherein said memory is a flash memory.
