Benefits of technology

The present invention aims to address issues and disadvantages by providing a mobile device with a sensor hub that controls sensors and adjusts sensor sampling periods based on the device's state. This helps to reduce power consumption and increase use convenience.

Problems solved by technology

This, however, increases the load of the main processors and thus deteriorates the control performance for the sensors.
This, however, increases the total overhead of the system.
If the main processor of a mobile device is set to have a relatively short wake-up period to rapidly measure the state values of the mobile device via sensors, power consumption increases.
On the other hand, if the main processor of a mobile device is set to have a relatively long wake-up period in order to reduce power consumption, the main processor cannot acquire proper state values of the mobile device via sensors.

Abstract

A mobile device with a sensor hub and sensors and a method for controlling the mobile device are provided. The method includes receiving state information regarding the mobile device, setting a sensor sampling period based on the received state information, and receiving measured values from one or more sensors according to the set, sensor sampling period. The sensor hub receives the state information regarding the mobile device, sets a sensor sampling period based on the received state information, and receives measured values from one or more sensors according to the set sensor sampling periods. The mobile device controls the sensors via the sensor hub irrespective of the operations of the main processor. The sensor hub sets a sensor sampling period based on the received state values of a mobile device.

Description

PRIORITY[0001]This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Jul. 18, 2012 in the Korean Intellectual Property Office and assigned Serial No. 10-2012-0078303, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a mobile device with a sensor hub for controlling sensors and a method for controlling the mobile device. More particularly, the present invention relates to a technology for setting a sensor sampling period based on state information regarding a mobile device via a sensor hub.[0004]2. Description of the Related Art[0005]Mobile devices with sensors according to the related are typically do not include separate processors for controlling the sensors. Accordingly, when the mobile devices enter sleep mode, a main processor must control the sensors. This, however, increases the load of the main processors and thus det...
