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—such as IDs. The acquired image data is processed by the device processor using a module application that resides within the device. The module includes indicators and/or alarms that can indicate success in reading an ID. A subframe removably mounts within the module'"'"'s main body/frame and carries the device. The subframe can vary to accommodate different devices within a single main body/frame geometry. The main body/frame includes appropriate structures (ports) to enable optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The main body/frame can also house a battery and charging assembly that supplies power to the device and allows charging through-for example and inductive charging unit.

Claims

1. A handheld vision system module comprising:

a main body having a main body inner edge that defines, at least in part, a main body top recess;

a subframe having a subframe outer perimeter and a subframe inner perimeter that defines, at least in part, a subframe top recess, the subframe being removably receivable within the main body inner edge and main body top recess, the subframe being adapted to receive and retain within the subframe top recess a handheld mobile device having a first device form factor;

processor circuitry located within the main body, the processor arranged to generate processed image data;

a battery, operatively connected with the processor circuitry, located within the main body; and

an imager module located on the main body and operatively connected with the processor circuitry arranged to acquire images of a scene and transmit image data to the processor circuitry, the imager module including a semi-cylindrical shell allowing for rotation of an optical axis of the imager module with respect to a longitudinal axis of the main body.

2. The handheld vision system as set forth in claim 1 wherein the battery is rechargeable and further comprising a charging circuit that recharges the battery from an external power source, and wherein the charging circuit is operatively connected to at least one of (a) an induction coil mounted on the main body, wherein an external charger includes an induction coil that selectively transmits energy to the induction coil mounted on the main body and (b) a connector mounted on the main body, wherein the external charger includes a connector that removably docks with the connector on the main body to transmit power therebetween.

3. The handheld vision system as set forth in claim 1 wherein the processor circuitry includes an imager processor having an ID decoding process, the imager processor being located in a module with an image sensor and optics.

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

5. The handheld vision system as set forth in claim 4 wherein the connector defines a USB form factor.

6. The handheld vision system as set forth in claim 5 wherein the connector is attached to a cable residing a receiving area.

7. The handheld vision system as set forth in claim 1 wherein the subframe outer perimeter engages the inner perimeter of the main body top recess with a friction fit.

8. The handheld vision system as set forth in claim 1 wherein the device includes a touch screen facing the user and that is covered with a sheet of transparent material providing a sealing layer against moisture, the sheet engaging an edge of the subframe to provide a seal therebetween.

9. The handheld vision system as set forth in claim 1 further comprising a switch button located on the main body and operatively connected to the processor circuitry, constructed and arranged to operate at least one of the imager and the mobile device.

10. The handheld vision system as set forth in claim 9 wherein the switch button is arranged to trigger acquisition of an image of the scene by the imager.

11. The handheld vision system as set forth in claim 1 further comprising an indicator located on the main body and operatively connected to the processor circuitry, constructed and arranged to report a status of at least one of the imager and the mobile device.

12. The handheld vision system as set forth in claim 11 wherein the status includes at least one of a successful decoding of an ID in the imaged scene and unsuccessful decoding of the ID in the imaged scene.

13. The handheld vision system as set forth in claim 1 wherein the imaged scene includes at least one ID and at least one of the processor circuitry and the mobile device module application is constructed and arranged to decode the ID and generate information related thereto.

14. The handheld vision system as set forth in claim 1 further comprising a second subframe, the second subframe including a second inner edge adapted to receive and retain a second handheld mobile device having a second device form factor, and a second module application running on the second mobile device having the second device form factor that allows receipt of, and manipulation of, image data provided by the circuitry acquired from the imager.

15. The handheld vision system as set forth in claim 1 further comprising a module application is arranged to transmit information related to the image data over a wireless link using a transceiver located in the mobile device.

16. The handheld device as set forth in claim 15 wherein the information comprises decoded ID information.

17. The handheld device as set forth in claim 1 wherein the imager is mounted in an imager module that includes an integral optics and illumination assembly, the illumination assembly including at least one of a scene illuminator and an aimer assembly.

18. The handheld device as set forth in claim 17 wherein the imager and illumination assembly are mounted in a module shell, the shell being constructed and arranged to rotate about at least one axis with respect to the main body.

19. The handheld device as set forth in claim 1 wherein the mobile device includes a native camera assembly on a side thereof opposite a side facing the user and wherein the main body includes a slot constructed and arranged to provide an optical path for the native camera assembly.

20. The handheld device as set forth in claim 1 where the subframe contains at least one of an authentication processor and interface conversion circuitry interconnecting the mobile device and the processor circuitry.

21. The handheld device as set forth in claim 1 wherein the processing circuitry and the battery are distinct and separate from the handheld mobile device.
