Abstract

A personal digital assistant (PDA) having a multi-positional handset is disclosed. A PDA has a base with a recessed handset cradle and a handset with a shape complementary to the configuration of the cradle. A power storage device is included within the handset and a power supply device is included within the base. For on-the-road use, the handset is configured to be removably secured within the cradle in a substantially flush configuration with the base. For office use, the handset is configured to be removably secured to the base in a substantially non-flush configuration that is easy for a user to grasp. The power storage device can receive power from the power supply device when the handset is in either a flush or non-flush configuration.

Claims

1. A personal digital assistant comprising:

a base having a recessed handset cradle and power supply means therewithin;

a handset having a configuration complementary to said cradle and configured to be removably secured within said cradle in a substantially flush configuration with said base, said handset having power storage means therewithin;

a first electrical connector within said cradle electrically connected to said power supply means;

a second electrical connector on said handset electrically connected to said power storage means, wherein said second electrical connector is configured to make electrical contact with said first electrical connector when said handset is in a substantially flush configuration;

an adapter having opposite first and second ends, said first end configured to be removably secured to said base overlying said first electrical connector, said second end configured to removably receive said handset therein; and

second means for electrically connecting said power storage means to said power supply means when said handset is removably secured to said base in a substantially non-flush configuration.

2. A personal digital assistant according to claim 1, wherein said first means for electrically connecting said power storage means to said power supply means when said handset is in a substantially flush configuration comprises:

a first electrical connector within said cradle electrically connected to said power supply means; and

a second electrical connector on said handset electrically connected to said power storage means, wherein said second electrical connector is configured to make electrical contact with said first electrical connector when said handset is in a substantially flush configuration.

3. A personal digital assistant according to claim 1, wherein said first electrical connector is integral with said base.

4. A personal digital assistant according to claim 1, wherein said second electrical connector is integral with said handset.

5. A personal digital assistant according to claim 1, wherein said second means for electrically connecting said power storage means with said power supply means when said handset is in a substantially non-flush configuration comprises means within said adapter for electrically connecting said first and second electrical connectors.

6. A personal digital assistant according to claim 5, wherein said means for electrically connecting said first and second electrical connectors comprises a plurality of conductive traces extending between said adapter first and second ends.

7. A personal digital assistant according to claim 1, further comprising:

a central processing unit within said base;

a display screen in communication with said central processing unit; and

means for providing user input to said central processing unit via said display screen.

8. A personal digital assistant comprising:

a base having a recessed handset cradle, said cradle having a first electrical connector electrically connected to a power supply;

a handset having a configuration complementary to said cradle and configured to be removably secured therewithin in a substantially flush configuration with said base, said handset comprising;

a medial portion having a second electrical connector electrically connected to a power storage device within said handset, said second electrical connector configured to engage said first electrical connector when said handset is in a substantially flush configuration to thereby electrically connect said power storage device with said power supply; and

an adapter configured to be removably secured to said base overlying said first electrical connector, said adapter having means for removably receiving an end portion of said handset such that said handset is in a substantially non-flush configuration with said base, and such that said second electrical connector is in electrical contact with said first connector.

9. A personal digital assistant according to claim 8, wherein said recessed handset cradle comprises a pair of opposing lip portions formed in opposing edge portions of said recessed handset cradle with said first electrical connector positioned therebetween.

10. A personal digital assistant according to claim 9, wherein said adapter comprises a pair of spaced apart biasing tabs extending outwardly therefrom, each tab configured to cooperate with a respective lip portion and thereby removably secure said adapter to said base.

11. A personal digital assistant according to claim 9, further comprising:

a central processing unit within said base;

a display screen in communication with said central processing unit; and

means for providing user input to said central processing unit via said display screen.

12. A personal digital assistant according to claim 9, wherein said adapter is formed from a thermoplastic material.

13. A personal digital assistant according to claim 12, wherein said thermoplastic material is polycarbonate.
