Reducing power consumption in a networked battery-operated device using sensors
View Patent ↗A method and system for mobile device power consumption management decreases the instantaneous power consumption of a mobile device, increasing operational lifetime of the device. In an embodiment of the invention, the mobile device is associated with a plurality of device behavior modification techniques that can be set in response to data collected from a plurality of sensors associated with the device. In an embodiment, the sensors detect the device's motion, tilt, proximity to a user, contact with a user, and orientation with respect to a user. In a further embodiment, the sensors detect a temperature related to the device or its environment.
1. A low power wireless device comprising:
a screen for displaying information to a user;
a ringer for audibly apprising the user of an incoming communication;
a vibrator for providing the user with a tactile prompt apprising the user of an incoming communication;
a network interface for interfacing the device to a wireless transceiver; and
a sensor array comprised of a plurality of sensors for sensing a plurality of qualities of an environment of the device and for yielding an output related thereto, wherein the sensor array output is utilized to affect the operation of at least one of the screen, the ringer, the vibrator, and the network interface, wherein when the sensor array output indicates that a user is looking at the device screen, the operation of the ringer and vibrator are affected so that in response to notification of an incoming communication received at the wireless interface, the ringer provides no audible signal, and the vibrator is not activated, and the operation of the screen is affected so that it does receive power.
2. The device according to claim 1 , wherein the screen receiving power causes the screen to display a visual notification of the incoming communication.
