Abstract: A vehicle seat includes a fixed frame installed in a vehicle body, a rotating link connected to the fixed frame through a rotation shaft and rotating relative to the rotation shaft, a seat cushion frame having one side of a rear end portion hinge-connected to the rotating link at a first connection point to rotate the rotating link when rotating, and a seat back frame having one side of a lower end portion hinge-connected to the fixed frame at a second connection point and the other side of the lower end portion hinge-connected to the other side of the rear end portion of the seat cushion frame at a third connection point to rotate relative to the fixed frame when the seat cushion frame is rotated.

Abstract: Methods and systems for transmitting location updates include determining a deviation distance, based on an extrapolated travel direction and an actual travel direction from a last updated location. It is determined that the deviation distance exceeds a deviation threshold. A location update is transmitted to a tracking server, responsive to the determination that the deviation distance exceeds the deviation threshold.

Abstract: Disclosed herein is a technology for detecting the location of a mobile computing device. A method for detecting the location of a mobile computing device includes the steps of (a) obtaining time, (b) storing the time and location information including GPS information and base station information associated with the time, and (c) obtaining base station information at the present time and estimating current GPS information without using a GPS if a correlation between the stored time and base station information is a specific reference or more.
