Abstract

A dual mode cradle, base station having a re-charging mode and a transmitting mode for wireless communication with a remote device and recharging a handheld scanning device is provided. The dual mode cradle, base station includes a transmitting subunit for wirelessly transmitting data originating from the handheld scanning device to a remote device; a re-charging subsystem disposed to be coupled to an electric power source for charging a battery within the handheld scanning device; and a scanning subsystem. The scanning subsystem includes the handheld scanning device; a polygon mirror adapted to rotably reflect a light path originating from the handheld scanning device, the light path disperse into a pattern for scanning a symbol.

Claims

1. A dual mode cradle, base station for a handheld scanning device, having a re-charging mode and a transmitting mode for wireless communication with a remote device and recharging the handheld scanning device, said dual mode cradle, base station comprising:

a transmitting subunit for wirelessly transmitting data originating from said handheld scanning device to a remote device;

a re-charging subsystem disposed to be coupled to an electric power source for charging a battery within said handheld scanning device; and

a scanning subsystem comprising;

a mechanical and electrical connection for said handheld scanning device; and

a rotatable polygon mirror positioned and constructed to reflect a light originating from said handheld scanning device when received in said connection, so that said light is dispersed into a pattern for scanning a symbol, the polygon mirror being selectively actuable to operate in conjunction with said, handheld device when received in said connection.

2. The dual mode cradle, base station of claim 1, further comprising a switch for switching between said re-charging mode and said transmitting mode;

whereby said handheld device is positioned at a single operable position for both said re-charging mode and said transmitting mode.

3. The dual mode cradle, base station of claim 1, wherein the reflected light of said polygon mirror is directed to and reflected from said symbol and is further processed by said handheld scanning device.

4. The dual mode cradle, base station of claim 1, wherein said light comprises laser light.

5. The dual mode cradle, base station of claim 1, wherein said symbol comprises barcode.

6. A dual mode scanning system comprising:

a handheld scanning device;

a dual mode cradle, base station disposed to receive said handheld scanning device for both recharging and using said handheld scanning device for fixed position scanning, said dual mode cradle, comprising;

a transmitting subunit for wirelessly transmitting data originating from said handheld scanning device to a remote device;

a re-charging subsystem disposed to be coupled to an electric power source for charging a battery within said handheld scanning device; and

a scanning subsystem comprising;

said handheld scanning device being mounted in the cradle; and

a polygon mirror mounted rotatably within the cradle and positioned so as to reflect a light path originating from said handheld scanning device, said light path being dispersed into a pattern for scanning a symbol;

said polygon mirror being selectively actuable to reflect said light path.

7. The system of claim 6, further comprising a switch for switching between said re-charging mode and said transmitting mode;

whereby said handheld device is positioned at a single operable position for both said re-charging mode and said transmitting mode.

8. The system of claim 6, wherein the reflected light of said light path from said symbol is further processed by said handheld scanning device.

9. The system of claim 6, wherein said light path comprises laser light path.

10. The system of claim 6, wherein said symbol comprises barcode.

11. A base station for holding a handheld scanner, said base station including an omnidirectional scanning mirror, charging means, a mechanical interface for holding said hand held scanner, and control means for selectively operating the base station as scanner using either the omnidirectional scanning mirror in combination with the hand held scanner or the hand held scanner alone, or as a charging station for the hand held scanner.

12. The base station of claim 11 further comprising a subsystem enabling the base station to communicate with a remote device.

13. The base station of claim 11 wherein the scanning mirror comprises a rotatable polygon mirror positioned in a light path from said handheld scanner.

14. The base station of claim 13 further comprising a multi-angle mirror in said light path cooperating with said polygon mirror to provide a two-dimensional scan pattern of light.

15. The base station of claim 11 wherein the scanning mirror comprises a multi-angle mirror positioned in a light path from said handheld scanner.
