| 发明名称 | Detecting physical separation of portable devices | ||
| 摘要 | A method for detecting physical separation between a first device and a second device includes identifying a moving state of the first device. A first set of motion data is collected for the first device responsive to identifying the moving state. A second set of motion data is received from a second device. The first and second sets of motion data are compared to determine a motion consistency metric. An alert signal is generated responsive to the motion consistency metric being less than a predetermined threshold. | ||

| 主权项 | 1. A method for detecting physical separation between a first device and a second device, comprising: identifying a moving state of the first device; collecting a first set of motion data for the first device responsive to identifying the moving state; sending a motion signal to the second device responsive to identifying the moving state of the first device receiving a second set of motion data from a second device responsive to identifying the moving state and responsive to the moving signal; comparing the first and second sets of motion data to determine a motion consistency metric; and generating an alert signal responsive to the motion consistency metric being less than a predetermined threshold. | ||
