Methods, systems, and apparatuses for detecting activation of an electronic device

An electronic device comprising:

• first means for sensing proximity to or contact with a body, wherein the first sensing means includes a first capacitance sensor;
• second means for sensing proximity to or contact with a body, wherein the second sensing means includes at least one of a capacitance sensor, an impedance sensor, an ohmic sensor, a mechanical switch, or any combination thereof;
• means for housing a circuit board and the first sensor;
• means for sensing detachment of a base from a housing of the circuit board and the first sensor;
• and
• means for controlling the electronic device coupled to the first sensing means and the second sensing means, wherein the controlling means is configured to:
• receive a first signal from the first sensing means;
• determine whether the electronic device is in close proximity to or in contact with the body based on the first signal;
• receive, in response to determining that the electronic device is in close proximity to or in contact with the body, a second signal from the second sensing means;
• receive a third signal indicating detachment of the base from the housing;
• and
• determine whether the electronic device is activated based on the first signal, the second signal, the third signal, or any combination thereof.

A method of an electronic device in a low-power mode for determining whether the electronic device is activated, the method comprising:

• receiving a first signal from a first sensor;
• determining whether the electronic device is in close proximity to or in contact with a body based on the first signal;
• receiving, in response to determining that the electronic device is in close proximity to or in contact with the body, a second signal from a second sensor;
• receiving a third signal from an antenna indicating whether a base has been detached from a housing of the first sensor;
• determining whether the electronic device is activated based on the first signal, the second signal, the third signal, or any combination thereof;
• and
• causing the electronic device to transition from a low-power mode to an active mode in response to determining that the electronic device is activated and the electronic device being in the low-power mode.
