Cover accessory device for a portable electronic and/or computer apparatus, and apparatus provided with such an accessory device
First Claim
1. A device for a portable electronic user apparatus comprising:
- a foldable part in order to cover at least one part of said user apparatus when it is folded onto said user apparatus, wherein said foldable part comprises at least two layers, one of the layers configurable to act as a capacitive detection electrode and another of the layers configurable to act as a guard layer placed at a guard potential for guarding the capacitive detection electrode;
a first of said at least two layers being further configurable to perform a capacitive detection function of at least one command object located on one side of said foldable part; and
a second of said at least two layers being further configurable to perform a capacitive detection function of at least one command object located on another side of said foldable part;
in order to trigger a function in said user apparatus.

Abstract
The present invention relates to a device for a portable user apparatus, including a portion which can be folded over the user apparatus, said foldable portion including at least two detection layers, each kept at a guard potential and including at least one capacitive detection electrode: a first of said layers being arranged to carry out a function of capacitive detection of at least one control object located on one side of said foldable portion; a second of said layers being arranged so as to carry out a function of capacitive detection of at least one control object located on the other side of said foldable portion, with a view to triggering a function in the user apparatus. The invention also relates to an apparatus provided with such an accessory device.

17. A method of providing object detection for a portable electronic user apparatus, comprising:
-
covering at least a part of said user apparatus with a foldable part, wherein said foldable part comprises at least two layers, one of the layers configurable to act as a capacitive detection electrode and another of the layers configurable to act as a guard layer placed at a guard potential for guarding the capacitive detection electrode; detecting objects using a first of said at least two layers on a first side of the foldable part while guarding the first layer with a guard potential; detecting objects using a second of said at least two layers a second side of the foldable part while guarding the second layer with the guard potential; and triggering a function in said user apparatus based on the detection of the objects. - View Dependent Claims (18, 19, 20)
