Method of accepting a phone call based on motion properties of the phone and related device
View Patent ↗A method of accepting a phone call comprises applying a force to the phone when receiving an incoming phone call on the phone to effect motion properties on the phone, detecting the motion properties of the phone, and deciding whether to accept the incoming phone call according to the motion properties.
1. A phone answering system, comprising:
a gyroscope for detecting a rotational velocity at which a phone is rotated when the phone is receiving an incoming phone call, the rotational velocity having a magnitude; and
a switch coupling to the gyroscope to receive the magnitude of the rotational velocity, the switch controlling the phone to answer the incoming phone call according to the magnitude of the rotational velocity.
2. The system of claim 1 , further comprising a comparator connecting with the gyroscope and the switch, wherein the comparator compares the magnitude of the rotational velocity with a predetermined rotational velocity value and provides a comparison result to the switch.
3. The system of claim 2 , wherein the comparator comprises a fixed voltage circuit for outputting a first voltage value if the magnitude of the rotational velocity is less than or equal to the predetermined rotational velocity value, and for outputting a second voltage value if the magnitude of the rotational velocity is greater than the predetermined rotational velocity value.
4. The system of claim 3 , wherein the fixed voltage circuit further comprises an amplifier circuit for amplifying the first voltage value or the second voltage value output by the fixed voltage circuit to create an amplified voltage value, and for outputting the amplified voltage value to the switch to control the switch.
5. The system of claim 1 , wherein the gyroscope is a micro-gyroscope.
6. The system of claim 1 , wherein the phone is a mobile phone.
