Mobile device and method of determining a state transition of a mobile device

摘要

A mobile device comprises one or more sensors; a plurality of additional sensors; and logic configured to: obtain one or more first data outputs from the one or more sensors in a first state; obtain one or more second data outputs from the one or more sensors; determine whether there has been a transition from the first state to a second state, based on a difference between the one or more first data outputs and the one or more second data outputs; obtain one or more third data outputs from the plurality of additional sensors if there has been a transition from the first state to the second state; and compare the one or more third data outputs with stored data outputs obtained using the plurality of additional sensors in a third state, thereby determining whether the mobile device is in the third state.

1. A mobile device comprising:
a first set of sensors that includes one or more physical, hardware sensors configured to sense physical characteristics including at least one of acceleration, location, temperature and ambient noise; a second set of sensors that includes a plurality of additional physical, hardware sensors, wherein the number of sensors that are part of the second set of sensors varies according to the size of the difference in values between one or more first data outputs and one or more second data outputs; and logic configured to:
obtain the one or more first data outputs from the first set of sensors when the mobile device is in a first known state;obtain the one or more second data outputs from the first set of sensors;determine whether there has been a transition from the first state to a second, unknown state, based on a difference between the one or more first data outputs and the one or more second data outputs, wherein the mobile device stays in the second unknown state until the mobile device has received sensor inputs from a minimum threshold number of sensors in the second set of sensors;obtain one or more third data outputs from the second set of sensors if there has been a transition from the first state to the second state; andcompare the one or more third data outputs with stored data outputs previously obtained using the second set of sensors when the mobile device was in a third state, the third state being a state prior to the first state, thereby determining whether the mobile device is in the third state.
