July 30, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors LEE, Kiwon (Seoul, KR); LEE, Suyoung (Seoul, KR); KA, Hokyuong (Seoul, KR); KIM, Youngwoo (Seoul, KR), filed on March 10, 2014, was made available online on July 17, 2014.

The patent's assignee is Lg Electronics Inc.

News editors obtained the following quote from the background information supplied by the inventors: "The disclosure relates to a portable device, and more particularly, to a method for providing a voice recognition service by switching a portable device from standby mode to voice recognition service mode using a sensor.

"Along with the miniaturization of chip sets and the development of network technology, portable devices have ever increasing performance and diversified functions. Recently, the portable devices have evolved from traditional communication equipment to smart devices capable of providing various services to users. A portable device can even play the role of a personal assistant and this function is often called as an intelligent agent. Further, the portable device can provide optimized functions according to a user context using various sensors equipped in it."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "As portable devices get smaller, the battery capacity of the portable devices is limited in view of their sizes. In this context, power management is a very significant issue to the portable devices. Accordingly, there exists a need for minimizing power consumption according to a service provided by a portable device. In addition, it is necessary for the portable device to provide various services more readily according to a user's intention by means of sensors.

"Additional advantages, objects, and features of the disclosure will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the disclosure. The objectives and other advantages of the disclosure may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

"To achieve these objects and other advantages and in accordance with the purpose of the disclosure, as embodied and broadly described herein, a portable device includes a mechanical vibration sensor configured to sense vibrations having a magnitude equal to or larger than a threshold and generate an electrical signal, a motion sensor configured to sense a motion of the portable device, an audio sensor configured to receive a voice command, a sensor hub configured to control a plurality of sensors including the motion sensor and the audio sensor, and a main processor configured to execute an application and control the portable device. When the portable device is placed in standby mode, upon receipt of the electrical signal from the mechanical vibration sensor, the sensor hub is configured to switch from inactive state to active state and activate the motion sensor, and if a gesture pattern sensed through the motion sensor corresponds to a voice recognition service triggering gesture, the sensor hub is configured to switch the portable device to voice recognition service mode by activating the main processor.

"In another aspect of the disclosure, a method for providing a voice recognition service in a portable device includes activating a sensor hub by transmitting an electrical signal to the sensor hub, upon sensing vibrations having a magnitude equal to or larger than a threshold by a mechanical vibration sensor, activating a motion sensor connected to the sensor hub by the sensor hub, activating a main processor by the sensor hub, if a gesture pattern sensed by the motion sensor matches a voice recognition service triggering gesture, and switching the portable device from standby mode to voice recognition service mode by the main processor.

"It is to be understood that both the foregoing general description and the following detailed description of the disclosure are exemplary and explanatory and are intended to provide further explanation of the disclosure as claimed.
