Abstract

A sleeve or case for a mobile device, such as a smartphone or tablet or other types of hand-held device or mobile smart device, has a sleeve part for at least partially enclosing the mobile device and an input device arranged in the sleeve part for controlling the mobile device which can be received in the sleeve part. The input device includes a movable control element and a magnetorheological brake. Any movement of the control element can be selectively damped by way of the magnetorheological brake.

First claim

The invention claimed is:

1 . A sleeve apparatus for a mobile device, the sleeve apparatus comprising:
a sleeve part for at least partially encasing the mobile device; and an input apparatus mounted to said sleeve part, said input apparatus being configured to activate the mobile device held in said sleeve part; said input apparatus including at least one movable operating element and at least one braking apparatus, said braking apparatus being configured to damp a movement of said operating element in a targeted fashion; and a sensor configured to detect an actuating position of said operating element, and a control apparatus configured to actuate said braking apparatus depending on the actuating position of said operating element.

2 . The sleeve apparatus according to claim 1 , wherein said braking apparatus is a magnetorheological brake.

3 . The sleeve apparatus according to claim 2 , wherein said braking apparatus comprises a magnetorheological medium and a field-generating apparatus for generating and controlling a magnetic and/or electrical field strength, and wherein said field-generating apparatus is configured to influence said medium in order to set a torque for a rotatability of said operating element.

4 . The sleeve apparatus according to claim 1 , wherein a damping of said operating element is set depending on an angle of rotation, detected by said sensor, and adapted in a targeted fashion.

5 . A sleeve apparatus for a mobile device, the sleeve apparatus comprising:
a sleeve part for at least partially encasing the mobile device; and an input apparatus mounted to said sleeve part, said input apparatus being configured to activate the mobile device held in said sleeve part; said input apparatus including at least one movable operating element and at least one braking apparatus, said braking apparatus being configured to damp a movement of said operating element in a targeted fashion; and a control apparatus configured for activating said braking apparatus in dependence on at least one control command and for converting the control command into a haptic signal that is perceptible at said operating element, to provide a user with haptic feedback as a consequence of an input by the user through said operating element.

6 . The sleeve apparatus according to claim 5 , wherein the control command is issued by the mobile device, by an application installed on the mobile device, or by said control apparatus.

7 . The sleeve apparatus according to claim 1 , wherein said input apparatus is configured to be coupled to the mobile device wirelessly or by a wired connection, enabling the mobile device held in the sleeve part to be operated by said input apparatus and/or enabling the mobile device to transmit signals to said input apparatus.

8 . The sleeve apparatus according to claim 1 , further comprising an electrical energy storage device for supplying said input apparatus with electrical energy or wherein said input apparatus is supplied with energy from an energy store of the mobile device.

9 . A sleeve apparatus for a mobile device, the sleeve apparatus comprising:
a sleeve part for at least partially encasing the mobile device; and an input apparatus mounted to said sleeve part, said input apparatus being configured to activate the mobile device held in said sleeve part; said input apparatus including at least one movable operating element and at least one braking apparatus, said braking apparatus being configured to damp a movement of said operating element in a targeted fashion; and said sleeve part and said input apparatus being optimized for operation by a right-handed user or said sleeve part and said input apparatus being optimized for operation by a left-handed user.

10 . The sleeve apparatus according to claim 1 , wherein said sleeve part comprises two holding cases each for holding one input apparatus, and wherein said input apparatus is selectively inserted into one of said holding cases.

11 . The sleeve apparatus according to claim 1 , wherein said operating element comprises at least two actuating zones, and wherein a movement of said operating element can be damped in a targeted fashion depending on the actuating zone at which said operating element is actuated (e.g., touched).

12 . The sleeve apparatus according to claim 11 , wherein the actuating zones are haptically distinguishable by way of a feature selected from the group consisting of a different surface, a different surface structure, a different size, a different geometry, a different color, and a different material, and wherein the haptic feedback takes place depending on the actuating zone in which the operating element is actuated (e.g. touched).

13 . The sleeve apparatus according to claim 11 , wherein the actuating zones are configured for operating in each case at least one specific function of the mobile device such that a different function of the mobile device can be activated depending on which of the actuating zones is actuated.

14 . The sleeve apparatus according to claim 11 , wherein an actuation of a respective actuating zone is detected via sensors by at least one monitoring apparatus.

15 . The sleeve apparatus according to claim 1 , wherein a first input is executed by a first movement of the operating element, and wherein at least one further input is executed by moving the operating element further, and wherein a different damping is provided for the first movement than for the further movement, and wherein a targeted increase in a retarding torque takes place after the first movement such that additional force needs to be expended for the further movement.

16 . The sleeve apparatus according to claim 15 , wherein at least one function is started by the first movement of the operating element, and wherein an adaptation of the function takes place by the further movement of the operating element.

17 . The sleeve apparatus according to claim 1 , wherein the control apparatus is configured for supplying a haptic signal which is perceptible at the operating element and which serves as an aid for a user having an impairment.

18 . The sleeve apparatus according to claim 1 , wherein a movement of said operating element executes at least one action selected from the group consisting of zooming, scrolling, selecting a camera, controlling a call, and selecting a menu.

19 . The sleeve apparatus according to claim 1 , wherein said operating element is configured to move a highlight of a display region by at least one movement of said operating element, and to activate a highlighted operation by pushing or rotating of said operating element.

20 . A sleeve apparatus for a mobile device, the sleeve apparatus comprising:
a sleeve part for at least partially encasing the mobile device; and an input apparatus mounted to said sleeve part, said input apparatus being configured to activate the mobile device held in said sleeve part; said input apparatus including at least one movable operating element and at least one braking apparatus, said braking apparatus being configured to damp a movement of said operating element in a targeted fashion; said sleeve part being a foldable structure and having at least two sleeve sections which are movably connected by at least one hinge, and said input apparatus being integrated into said hinge apparatus.
