Abstract

This invention provides a module for a handheld device. The module includes an imager with optics and image acquisition/processing processors that provide high speed acquisition and handling of acquired image data. The acquired image data is processed by the device processor using a module application that resides within the device. A removable retaining component mounts within the module'"'"'s base portion. The retaining component varies to accommodate different devices. The base portion includes appropriate ports enabling optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The base portion also houses a battery and charging assembly e.g. an inductive charging unit. The inductive charging unit can be adapted to pass data, in addition to power, between the inductive coils and the charging unit can be interconnected to a data network with attached devices that employ data from the module.

Claims

1. A handheld vision system module comprising:

a body constructed and arranged to be gripped by a hand of a user, the body having a base assembly that is adapted to removably attach a mobile device thereinto;

a processor located within the base assembly, the processor arranged to generate processed image data;

an imager located relative to the base assembly, and operatively connected with the processor circuitry, the imager being arranged to acquire images of a scene and transmit image data to the processor;

a module application running on the mobile device that allows receipt of, and manipulation of, the processed image data;

a base assembly charging circuit within the base assembly that recharges a battery within the module, the base assembly charging circuit interconnected to a base assembly induction coil to deliver power to the charging circuit from an EM power signal;

a base assembly EM signal converter, interconnected the base assembly charging circuit, that injects and extracts an EM data signal with respect to the EM power signal;

an external charging unit having a charging unit charging circuit and an associated charging unit induction coil that generates the EM power signal, wherein the charging unit interconnects via a network with other data handling devices/processors; and

a charging unit EM signal converter, interconnected to the charging unit charging circuit, that inserts and extracts the EM data signal with respect to the EM power signal.

2. The handheld vision system module as set forth in claim 1, further comprising an interface that is connected between the base assembly EM signal converter and the mobile device.

3. The handheld vision system module as set forth in claim 2, further comprising an interface that is connected between the charging unit EM signal converter and the network

4. The handheld vision system as set forth in claim 1 wherein the network interconnects to one or more external data handling devices that are adapted to receive and manipulate vision system information from the module.

5. The handheld vision system as set forth in claim 4 wherein the processor has an imager processor having an ID-decoding process, the imager processor being located in combination with an image sensor and optics in a pod within the base portion.

6. The handheld vision system as set forth in claim 4 wherein the module is arranged to transfer the vision system information between the base assembly induction coil and the charging unit induction coil when power flows therebetween.

7. The handheld vision system as set forth in claim 4 wherein the charging unit is interconnected to the network through a wired LAN.

8. The handheld vision system as set forth in claim 1, further comprising a connector, operatively connected with the processor, that attaches to a connection on the device for receiving power and data.

9. The handheld vision system as set forth in claim 8 wherein the connector defines either an Apple or USB form factor.

10. The handheld vision system as set forth in claim 1, further comprising at least one function button located on the base assembly and operatively connected to the processor, constructed and arranged to operate at least one of the imager and the mobile device.

11. The handheld vision system as set forth in claim 10 wherein the function button is arranged to trigger acquisition of an image of the scene by the imager.

12. The handheld vision system as set forth in claim 1, further comprising an indicator mounted on the base assembly and operatively connected to the processor, constructed and arranged to report a status of at least one of the imager and the mobile device.

16. The method as set forth in claim 1, further comprising operating the application on the mobile device to control at least one of the processor and the imager.

13. A method for charging a handheld vision system module comprising:

providing a body constructed and arranged to be gripped by a hand of a user, the body having (a) a base assembly and a processor located within the base assembly, the processor arranged to generate processed image data and (b) an imager located relative to the base assembly, and operatively connected with the processor;

acquiring images of a scene with the imager, image data being transmitted to the processor;

operating a module application running on the mobile device that allows receipt of, and manipulation of, the processed image data;

removably docking the base assembly with respect to an external charging unit so that a base assembly charging circuit within the base assembly recharges a battery within the module with a base assembly induction coil that delivers power to the base assembly charging circuit from an EM power signal;

providing a base assembly EM signal converter, interconnected the base assembly charging circuit, that injects and extracts an EM data signal with respect to the EM power signal;

generating the EM power signal with a charging unit charging circuit and an associated charging unit induction coil, wherein the charging unit interconnects via a network with other data handling devices/processors; and

providing a charging unit EM signal converter, interconnected to the charging unit charging circuit, that inserts and extracts the EM data signal with respect to the EM power signal.

14. The method as set forth in claim 13, wherein the step of acquiring images includes acquiring images of an ID on an object and wherein the EM data signal includes data associated with the ID.

15. The method as set forth in claim 14 wherein the external charging unit transmits data associated with the ID based upon docking with the base assembly.

17. The method as set forth in claim 13, further comprising operating a function button on the base assembly to operate at least one of the imager and the mobile device.
