Abstract

A computer card data receiver (10) includes a housing (14) having a top planar surface (16) and a bottom planar surface (18) and a thin profile suited to fit within a recessed data interface port (32) of an external computer (30). An antenna (12) is coupled to the top planar surface (16) of the housing (14) for intercepting transmitted selective call address signals and data associated therewith. The antenna (12) is rotatable between a first antenna position (12A) and a second antenna position (12B), the first antenna position (12A) being selected when the housing (14) is removed from the recessed data interface port (32), and the second antenna position (12B) being selected when the housing (14) is inserted into the recessed data interface port (32). A receiver (40) is enclosed within the housing (14) and receives and detects the intercepted selective call address signals and data associated therewith.

Claims

1. A computer card data receiver, comprising:

a housing having a top planar surface and a bottom planar surface and a thin profile suited to fit within a recessed data interface port of an external computer;

an antenna for intercepting transmitted selective call address signals and data associated therewith, said antenna being enclosed within a hinged planar housing member which is coupled to said top surface of said housing and which is selectably rotatable between a first position to provide a first operative orientation of said antenna and a second position to provide a second operative orientation of said antenna, said first position being selected when said housing is removed from said recessed data interface port, and said second position being selected when said housing is inserted into said recessed data interface port; and

receiver means, enclosed within said housing and coupled to said antenna, for receiving and detecting the intercepted selective call address signals and data associated therewith.

2. The computer card data receiver according to claim 1, wherein said first position orients said antenna parallel to the plane of said top planar surface when said antenna is removed from said recessed data interface port.

3. The computer card data receiver according to claim 1, wherein said second position orients said antenna perpendicular to the plane of said top planar surface when said antenna is inserted into said recessed data interface port.

4. The computer card data receiver according to claim 1, further comprising:

processing means, coupled to said receiver means, for processing the detected selective call address signals to enable receiving the data associated therewith; and

data interface means, coupled to said recessed data interface port and responsive to said processing means, for transferring the received data to said external computer through said recessed data interface port.

5. The computer card data receiver according to claim 4, wherein said data interface means includes connector means for providing connection between said processing means and said external computer through said recessed data interface port.

6. The computer card data receiver according to claim 5, wherein said connector means provides a data port constructed and operated in accordance with the Personal Computer Memory Card International Association (PCMCIA) standard.

7. The computer card data receiver according to claim 1, wherein said antenna comprises

a magnetic loop antenna coupled to said receiver means.

8. The computer card data receiver according to claim 1, wherein said antenna comprises

an electric dipole antenna coupled to said receiver means.

9. The computer card data receiver according to claim 1, wherein said external computer is a portable laptop computer.

10. A computer card data receiver comprising:

a housing, having a first housing portion having a top planar surface and a bottom planar surface and a thin profile suited to fit within a recessed data interface port of an external computer, and a second housing portion remaining external to said recessed data interface port, said second housing portion having a top planar surface, and a bottom planar surface contiguous with said bottom planar surface of said first housing portion;

an antenna for intercepting transmitted selective call address signals and data associated therewith, said antenna being enclosed within a hinged planar housing member which is couple to said top surface of said second housing portion and which is rotatable between a first position to provide a first operative orientation of said antenna and a second position to provide a second operative orientation of said antenna, said first position being selected when said housing is removed form said recessed data interface port, and said second position being selected when said housing is inserted into said recessed data interface port;

a printed circuit board;

receiver means, supported on said printed circuit board and enclosed within said first housing portion, for receiving and detecting the intercepted selective call address signals and data associated therewith; and

a battery, enclosed within said second housing portion, for supplying power to said receiver means.

11. The computer card data receiver according to claim 10, wherein said first position orients said antenna means parallel to the plane of said top planar surface of said second housing portion when said antenna is removed from said recessed data interface port.

12. The computer card data receiver according to claim 11, wherein said top planar surface of said second housing portion includes a recess for enclosing said antenna when said antenna is placed in said first position.

13. The computer card data receiver according to claim 10, wherein said second position orients said antenna perpendicular to the plane of said top planar surface of said second housing portion when said antenna is inserted into said recessed data interface port.

14. The computer card data receiver according to claim 10, further comprising:

processing means, supported on said printed circuit board, for processing the detected selective call address signals to enable receiving the data associated therewith; and

data interface means, supported on said printed circuit board and coupled to said recessed data interface port and responsive to said processing means, for transferring the received data to said external computer through said recessed data interface port.

15. The computer card data receiver according to claim 14, wherein said data interface means includes connector means, supported by said printed circuit board, for providing connection between said processing means and said external computer through said recessed data interface port.

16. The computer card data receiver according to claim 15, wherein said connector means provides a data port constructed and operated in accordance with the Personal Computer Memory Card International Association (PCMCIA) standard.

17. The computer card data receiver according to claim 10, wherein said antenna comprises

a magnetic loop antenna coupled to said receiver means.

18. The computer card data receiver according to claim 10, wherein said antenna comprises

an electric dipole antenna coupled to said receiver means.

19. The computer card data receiver according to claim 10 further comprising means for latching said hinged planar housing member into said first position.

20. The computer card data receiver according to claim 10, wherein said external computer is a portable laptop computer.
