Abstract

A reconfigurable sled for a mobile device with camera is provided. The reconfigurable sled may be moved into different configurations in order to facilitate either normal or specialized use. For example, in a first configuration, the mobile device'"'"'s camera is unobstructed and imaging may proceed normally. In a second configuration, on the other hand, the camera'"'"'s imaging direction may be repositioned by a reflective element in the camera'"'"'s optical path. The reflective element provides feedback to the mobile device via visible markings that may be imaged by the camera and detected by the mobile device. If the mobile device determines that the mirror is in the optical path, then the mobile device may respond to accommodate the mirror and enable a function, like reading an indicium.

Claims

1. A reconfigurable sled for a mobile device with a camera, the sled comprising:

a frame for holding the mobile device, the frame configured with guides running along two sides; and

a cover comprising a plurality of hinged panels engaged with the guides so that the panels are slideable along the guides and folded into different configurations, wherein

at least one of the hinged panels is attached to the frame at one end,

in a first configuration the hinged panels lie flat over the mobile device'"'"'s back surface and permit the camera an unobstructed view, and

in a second configuration two of the hinged panels are folded to form a peak over the mobile device'"'"'s back surface and redirect the camera'"'"'s field-of-view using a reflective element affixed to one of the folded hinged panels, the reflective element comprising a mirror with visible markings for indicating that the mirror is in the camera'"'"'s field-of-view.

2. The reconfigurable sled for a mobile device with a camera according to claim 1, wherein the camera comprises an illuminator and light from the illuminator is redirected by the reflective element in the second configuration.

3. The reconfigurable sled for a mobile device with a camera according to claim 1,

wherein the hinged panels comprise:

a window panel having an aperture for the camera to image through, the window panel hingedly attached to the frame along the window panel'"'"'s top edge;

a mirror panel configured with a reflective element for folding the camera'"'"'s imaging direction, the mirror panel hingedly attached to the window panel'"'"'s bottom edge; and

a slider panel for repositioning the window panel and the mirror panel, the slider panel hingedly attached to the mirror panel'"'"'s bottom edge and engaged on the slider panel'"'"'s sides by the frame'"'"'s guides so that (i) the slider panel is free to slide within the guides and (ii) the slider panel holds the mobile device in the frame.

4. The reconfigurable sled for a mobile device with a camera according to claim 1, wherein an application running on the mobile device senses the visible markings and configures the mobile device for indicia reading.

5. A reconfigurable sled for a mobile device with a camera,

the sled comprising:

a frame for holding the mobile device, the frame configured with guides running along two sides; and

a cover comprising a plurality of hinged panels engaged with the guides so that the panels may be slid along the guides and folded into different configurations, wherein

at least one of the hinged panels is attached to the frame at one end,

in a first configuration the hinged panels lie flat over the mobile device'"'"'s back surface and permit the camera an unobstructed view, and

in a second configuration two of the hinged panels are folded to form a peak over the mobile device'"'"'s back surface and redirect the camera'"'"'s field-of-view using a reflective element affixed to one of the folded hinged panels; and

wherein the hinged panels comprise;

a window panel having an aperture for the camera to image through, the window panel hingedly attached to the frame along the window panel'"'"'s top edge;

a mirror panel configured with a reflective element for folding the camera'"'"'s imaging direction, the mirror panel hingedly attached to the window panel'"'"'s bottom edge; and

a slider panel for repositioning the window panel and the mirror panel, the slider panel hingedly attached to the mirror panel'"'"'s bottom edge and engaged on the slider panel'"'"'s sides by the frame'"'"'s guides so that (i) the slider panel is free to slide within the guides and (ii) the slider panel holds the mobile device in the frame.

6. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein mirror panel comprises a lens to reduce the minimum focus distance of the camera.

7. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein the second configuration comprises the window panel folded 90 degrees with respect to the mobile device'"'"'s back surface and the mirror panel is folded 45 degrees with respect to the back surface so that camera'"'"'s field-of-view is redirected by the reflective element 90 degrees through the window panel aperture.

8. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein the slider panel and guides are configured with a locking mechanism to lock the cover into either the first configuration or the second configuration.

9. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein the cover may be moved into the first configuration or the second configuration by pressing a button located on the sled.

10. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein the window panel comprises a transparent window covering the aperture.

11. The reconfigurable sled for a mobile device with a camera according to claim 5, wherein the reflective element comprises a mirror with visible markings for indicating that the mirror is in the camera'"'"'s field-of-view.

12. An indicia reading system comprising:

a mobile device comprising a camera, an illuminator, and a processor configured for running applications;

a reconfigurable sled for holding the mobile device and enabled to change imaging characteristics of the mobile device, the reconfigurable sled comprising a mirror to redirect an imaging direction of the camera when the mirror is moved into a field-of-view of the camera, the mirror having visible markings that appear in images of the field-of-view reflected from the mirror; and

an indicia reading application running on the mobile device, the indicia reading application configuring the mobile device to (i) acquire images, (ii) analyze the acquired images for the visible markings, and (iii) adjust the mobile device for indicia reading if the visible markings are detected.

13. The indicia reading system according to claim 12, comprising a lens integrated with the reconfigurable sled for adjusting the focus of the camera when the mirror is moved into the camera'"'"'s field-of-view.

14. The indicia reading system according to claim 12, comprising a motion control subsystem for moving the mirror, the motion control subsystem electrically coupled to the mobile device and controllable by the indicia reading application.

15. The indicia reading system according to claim 14, comprising a battery for powering the motion control subsystem.

16. The indicia reading system according to claim 12, comprising an aimer subsystem for projecting an aiming pattern into the camera'"'"'s field-of-view to help a user align an indicium for reading.

17. The indicia reading system according to claim 16, wherein the aimer subsystem comprises an (i) aimer light source for generating light, (ii) an aimer aperture covering the aimer light source for shaping the light from the aimer light source into an aiming pattern corresponding to the orientation and extent of the camera'"'"'s field-of-view, and (iii) an aimer lens for projecting the illuminated aimer aperture onto a target.

18. The indicia reading system according to claim 17, wherein the aimer light source is the mobile device'"'"'s illuminator.
