Abstract

A hand-holdable docking station is adapted for mechanical and electrical connection with a palmtop computer. The docking station comprises a housing and means for securely affixing a palmtop computer to the housing. A deployable light source is housed/stored in a receptacle provided in the housing. The light source is deployable to a position such that the illumination footprint illuminates the screen of an attached palmtop computer but does not obscure viewing of the screen. The docking station includes a rechargeable battery pack for providing power to the deployable light source and the attached palmtop computer. Grasping means are included for ergonomic positioning of a human hand to allow substantially fatigue free handling of the docking station and for positioning a grasping hand such that the hand does not obscure viewing of the attached palmtop computer screen. The docking station also includes an electronic function board further including a facsimile/modem, a microprocessor and memory, and a pager connected to the microprocessor for receiving alpha/numeric page signals in excess of 55 characters per alpha page session.

Claims

1. A hand-holdable docking station adapted for mechanical and electrical connection with a palmtop computer, the docking station comprising:

a housing having a top, a bottom, a left side, a right side, and front and back faces, the housing for enclosing and defining an interior volume;

means for securely affixing a palmtop computer to the docking station;

a deployable light source, housed/stored in a receptacle, provided in the housing, when the light source is in an undeployed position, the light source being deployable to a position such that the illumination footprint illuminates the screen of an attached palmtop computer, wherein the light source is positioned such that it does not obscure the screen;

a rechargeable battery pack disposed within the housing, the battery pack for providing power to the deployable light source and the attached palmtop computer;

coupling means connected between the docking station and the palmtop computer for effecting electrical communication therebetween; and

at least one grip formed in the back face of the housing, the at least one grip including a recess in the back face of the housing into which the fingers of a human hand may be inserted, the recess spaced away from the sides of the housing a sufficient distance to form a griping surface having the shape of a cupped human hand when viewed in cross-section.

2. The docking station of claim 1, wherein coupling means comprises:

a power cable, the cable coupled between the rechargeable battery pack and the attached palmtop computer; and

an RS-232 communication cable.

3. The docking station of claim 2, further comprising:

a function board provided within the housing, the function board including electronic communication circuitry operatively responsive to signals communicated between the docking station and an attached palmtop computer over the RS-232 communication cable; and

an RJ-11 phone jack provided on the top of the housing, the phone jack in electrical communication with the function board.

4. The docking station of claim 3, wherein the RS-232 communication cable comprises a dual-in-line 8-pin serial connector, the serial connector configured to mate with a serial port provided on an attached palmtop computer.

5. The docking station of claim 4, wherein the function board includes a facsimile/modem circuit.

6. The docking station of claim 4, the function board further comprising:

a microprocessor;

a memory coupled to the microprocessor;

pager subsystem circuitry connected to the microprocessor for receiving alpha/numeric page signals, the pager circuitry including means for signaling the microprocessor that a page is incoming, the microprocessor receiving the page signals from the pager circuitry and storing the page signals in the memory such that alpha/numeric pages in excess of 55 characters are received by the pager subsystem circuitry during a single alpha page session; and

means for alerting a user that a page has been received.

7. The docking station of claim 6, the pager subsystem circuitry configured to receive page signals in the about 150 to about 450megahertz frequency bands.

8. The docking station of claim 6, wherein the pager subsystem circuitry includes means for receiving page signals in the 900 megahertz frequency band.

9. A hand-holdable docking station adapted for mechanical and electrical connection with a palmtop computer, the docking station comprising:

a housing having a top, a bottom, a left side, a right side, and front and back faces, the housing for enclosing and defining an interior volume;

means for securely affixing a palmtop computer to the docking station;

means for illuminating the screen of an attached palmtop computer, the illumination means disposed such that the entire screen is unobstructed when viewed from a position normal to the screen, the illumination means further having an illumination footprint substantially equal to the plane dimensions of the computer screen;

a rechargeable battery pack disposed within the housing, the battery pack providing power to the illumination means and the attached palmtop computer;

coupling means connected between the docking station and the palmtop computer for effecting electrical communication therebetween; and

grasping means formed in the back face of the housing, the grasping means including a recess disposed in the back face of the housing into which the fingers of a human hand may be inserted, the grasping means positioned such that when grasped, no part of a human hand obscures the screen of an attached palmtop computer.

10. The docking station of claim 9, the illumination means comprising a deployable light source, the light source disposed in a receptacle provided in the housing when the light source is in an undeployed position, the light source being deployable to a position such that the illumination footprint illuminates the screen of an attached palmtop computer.

11. The docking station of claim 10, the deployable light source further comprising:

a U-shaped support arm rotatably connected to the housing at a leg of the U; and

a light fixture housing, disposed at the distal end of the support arm, the light fixture housing including a light bulb and a cylindrical hood disposed to cover the bulb, the hood having a slit formed along a major surface thereof, the slit directing light from the bulb in a substantially wedge-shaped beam, the support arm positioning the light fixture housing such that the beam has a footprint substantially equal to the screen of an attached palmtop computer.

12. The docking station of claim 11, wherein the cylindrical hood is rotatable.

13. A hand-holdable docking station adapted for mechanical and electrical connection with a palmtop computer, the docking station comprising:

a housing;

means for securely affixing a palmtop computer to the housing;

a deployable light source, housed/stored in a receptacle, provided in the housing, when the light source is in an undeployed position, the light source being deployable to a position such that the illumination footprint illuminates the screen of an attached palmtop computer, wherein the light source is positioned such that it does not obscure the screen;

a rechargeable battery pack disposed within the housing, the battery pack for providing power to the deployable light source and the attached palmtop computer;

coupling means connected between the docking station and the palmtop computer for effecting electrical communication therebetween; and

means for grasping the housing, the grasping means providing for ergonomic positioning of a human hand to allow substantially fatigue free handling of the docking station, the grasping means further for positioning a grasping hand such that the hand does not obscure viewing of the attached palmtop computer screen.

14. The docking station of claim 13, the grasping means comprising at least one grip formed in the housing, the at least one grip including a recess formed in a back face of the housing into which the fingers of a human hand may be inserted, the recess spaced away from the sides of the housing a sufficient distance to form a griping surface having the shape of a cupped human hand when viewed in cross-section.
