Abstract

An accessory for processor-based mobile devices is selectively securely attachable to the mobile device and at least partially wraps around at least one edge of the mobile device, so that a photo-reflective dipolar electronic display incorporated into the outer shell of the accessory can provide a visual platform for sustained image retention with negligible power consumption. Content (e.g., image data) is transmitted wirelessly from the mobile device to the accessory. Electronic and/or electrical components for receiving, directing, decrypting, and displaying images can be incorporated into a resilient sleeve, integrated into a hard shell case, or a combination of the two. Content can originate in the mobile device, or at a remote content server, to periodically update an image on the accessory.

Claims

1. An accessory for processor-based mobile devices, the accessory comprising:

a body that is selectively securely attachable to a processor-based mobile device;

a photo-reflective dipolar electronic display carried by the body and which in use at least partially wraps about at least one edge of the processor-based mobile device;

a wireless receiver and at least one antenna carried by the body, the wireless receiver operable to at least receive wireless communications from the processor-based mobile device at least when the body is securely attached to the processor-based mobile device, the wireless communications including image data for display via the photo-reflective dipolar electronic display;

a drive circuit communicatively coupled between the wireless receiver and the photo-reflective dipolar electronic display to at least drive the photo-reflective dipolar electronic display in response to received image data; and

a power transducer carried by the body and electrically coupled to supply power to at least one of the drive circuit or the photo-reflective dipolar electronic display and which receives power from a source external from the accessory.

2. The accessory of claim 1 wherein the body is a resilient silicone sleeve.

3. The accessory of claim 2 wherein at least the wireless receiver and the drive circuit are encapsulated in the resilient silicone sleeve.

4. The accessory of claim 2, further comprising:

a hard shell case that is received about a portion of the resilient silicone sleeve and the processor-based mobile device.

5. The accessory of claim 1 wherein the body is a hard shell case having a base and a number of resilient portions extending from the base.

6. The accessory of claim 5 wherein at least the wireless receiver and the drive circuit are encapsulated in the hard shell case.

7. The accessory of claim 5, further comprising:

a resilient silicone sleeve that is resiliently secured to about a portion of the processor-based mobile device, and about which the hard shell case is at least partially received.

8. The accessory of claim 1 wherein the power transducer includes at least one photovoltaic cell to harvest energy from light in an ambient environment.

9. The accessory of claim 8 wherein the body has a base and a number of sides extending at least approximately from the base which deliminate an interior of the body, and the at least one photovoltaic cell is positioned in the interior of the body.

10. The accessory of claim 1 wherein the power transducer includes a rectifier circuit and a capacitor, coupled to the antenna to harvest energy from the wireless communications transmitted via the processor-based mobile device.

11. The accessory of claim 1 wherein the power transducer includes an inductive coil to inductively receive power from the processor-based mobile device.

12. The accessory of claim 1 wherein the photo-reflective dipolar electronic display is an e-paper display which retains an image for an extended period of time without drawing electrical power.

13. The accessory of claim 2, further comprising

a decryption integrated circuit communicatively coupled to the wireless receiver to decrypt the signals received via the wireless receiver.

14. A method of adjusting an external appearance of a processor-based mobile device, the method comprising:

partially wrapping around at least one edge of the processor-based mobile device, and including a power transducer, a drive circuit, a wireless receiver, and an antenna;

receiving power from a source external to the accessory, via the power transducer;

receiving image data from the mobile device via the antenna and wireless receiver;

displaying the received image data on an array of photo-reflective dipolar electronic elements carried by the accessory, in response to signals from the drive circuit, when power is applied to the array by the power transducer; and

sustaining the image data on the array of photo-reflective dipolar electronic elements after power is removed from the array.

15. The method of claim 14 wherein the receiving includes receiving encrypted image data from the mobile device via the antenna and wireless receiver, and further comprising decrypting the image data via an integrated circuit of the accessory.

16. The method of claim 14 wherein the receiving image data from the mobile device includes receiving personalized image data provided by a user.

17. The method of claim 14 wherein the receiving image data includes receiving image data captured using a camera of the mobile device.

18. The method of claim 14 wherein the receiving image data includes receiving image data via an application executing on the mobile device.

19. The method of claim 14 wherein the receiving image data includes receiving advertising image data pushed to the mobile device.

20. The method of claim 14 wherein the receiving image data includes receiving advertising image data pulled to the mobile device.
