Abstract
The present disclosure is directed to a device configured to detect whether the device is in a bag or outside of the bag. The device determines whether the device is in or outside of the bag based on distance measurements generated by at least one proximity sensor and motion measurements generated by at least one motion sensor. By using both distance measurements and motion measurements, the device is able to detect whether the device is in the bag or outside of the bag with high accuracy and robustness.
Claims21
A device, comprising:
- a motion sensor configured to generate motion measurements;
- a plurality of proximity sensors configured to generate distance measurements, the plurality of proximity sensor being positioned on different sides of the device;
- and
- a controller configured to:
- determine a motion state of the device based on the motion measurements, the motion state indicating the device is being inserted into a bag or taken out of the bag;
- determine whether the device is in a covered state or a non-covered state based on the distance measurements, the covered state indicating the device is covered by an object, the non-covered state indicating the device is not covered by the object;
- determine the device is in a state selected from an in-bag state and an out-of-bag state, the in-bag state indicating the device is in the bag, the out-of-bag state indicating the device is outside of the bag, the device being determined to be in the in-bag state in case the motion state indicates the device is being inserted into the bag and the device is in the covered state, the device being determined to be in the out-of-bag state in case the motion state indicates the device is being taken out of the bag or the device is not in the non-covered state;
- and
- adjust a power state of the device based on whether the device is in the in-bag state or the out-of-bag state.

A device, comprising:
- a motion sensor configured to generate motion measurements;
- a plurality of proximity sensors configured to generate distance measurements, each of the plurality of proximity sensors positioned at a respective side of the device;
- and
- a controller configured to:
- determine a motion state of the device based on the motion measurements, the motion state indicating that the device is being inserted into a bag;
- determine a covered state of the device based on the distance measurements, the covered state indicating the device is covered by an object;
- determine, in response to the motion state and the covered state being determined, the device is in an in-bag state indicating the device is in the bag;
- and
- adjust a power state of the device based on the determined state of the device.
