Low power mode for electronic devices

A system comprising:

• a device having a low power mode and a normal power mode, wherein:
• the normal power mode drives one or more sensors for monitoring,
• the low power mode provides reduced power consumption relative to the normal power mode, the low power mode including a sensing circuit that uses at least one of the one or more sensors for monitoring, wherein the at least one of the one or more sensors is coupled to the device in two parallel circuits including a first parallel circuit for the low power mode and a second parallel circuit for the normal power mode, and
• the device is configured to transition from the low power mode to the normal power mode in response to a signal;
• a waking module configured to detect a condition for transitioning from the low power mode to the normal power mode and, in response to detecting the condition, to provide the signal to the device for transitioning from the low power mode to the normal power mode;
• and
• a transition module configured to respond to the signal by transitioning to the normal power mode and permanently disabling the low power mode on the device.

A method comprising:

• providing a device,
• the device including a Hall effect sensor, a processor, and a memory, the processor configured by computer executable code stored in the memory to operate the device in a low power mode and a normal power mode,
• the normal power mode driving one or more sensors for monitoring,
• the low power mode including a sensing circuit that uses at least one of the one or more sensors for monitoring, wherein the at least one of the one or more sensors is coupled to the device in two parallel circuits including a first parallel circuit for the low power mode and a second parallel circuit for the normal power mode, and
• the processor configured to transition from the low power mode to the normal power mode in response to a signal from the Hall effect sensor;
• and
• placing the device in packaging, wherein:
• the packaging includes a magnet positioned as a sensor trigger to generate the signal with the Hall effect sensor when the device is removed from the packaging,
• the device is placed in the packaging in the low power mode, and
• the device is configured, responsive to entering the normal power mode, to disable the low power mode by deleting executable code for the low power mode from the memory of the device.
