Abstract
In one embodiment, a stylus includes one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device. The stylus also includes inductive-charging components in or on the stylus for charging or powering the stylus with electromagnetic radiation from inductive-charging components in or on the device. The inductive-charging components in or on the stylus may also charge or power the device by transmitting electromagnetic radiation to the inductive-charging components in or on the device.
Claims20
A stylus comprising:
- one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device;
- and
- a first inductive-charging component in or on the stylus for:
- charging or powering the stylus with electromagnetic radiation from a second inductive-charging component in or on the device, the second inductive-charging component comprising at least one or more drive or sense lines of the touch sensor of the device;
- or
- charging or powering the device with electromagnetic radiation from the first inductive-charging component to the second inductive-charging component.
A device comprising:
- a touch sensor;
- one or more computer-readable non-transitory storage media embodying logic for controlling the touch sensor and processing signals transmitted wirelessly by a stylus to the device through the touch sensor;
- and
- a first inductive-charging component comprising at least one or more drive or sense lines of the touch sensor of the device for:
- charging or powering the device with electromagnetic radiation from a second inductive-charging component in or on the stylus;
- or
- charging or powering the stylus with electromagnetic radiation from the first inductive-charging component to the second inductive-charging component.
A system comprising:
- a device comprising:
- a touch sensor;
- one or more first computer-readable non-transitory storage media embodying first logic for controlling the touch sensor and processing signals transmitted wirelessly by a stylus to the device through the touch sensor;
- and
- a first inductive-charging component comprising at least one or more drive or sense lines of the touch sensor of the device for:
- charging or powering the device with electromagnetic radiation from a second inductive-charging component in or on the stylus;
- or
- charging or powering the stylus with electromagnetic radiation from the first inductive-charging component to the second inductive-charging component;
- and
- the stylus, comprising:
- one or more electrodes and one or more second computer-readable non-transitory storage media embodying second logic for transmitting signals wirelessly to the device through the touch sensor of the device;
- and
- the second inductive-charging component, for:
- charging or powering the stylus with electromagnetic radiation from the first inductive-charging component;
- or
- charging or powering the device with electromagnetic radiation from the second inductive-charging components to the first inductive-charging component.
