| 20120169502 | ELECTRONIC BABY MONITORING DEVICE - An electronic baby monitoring device includes a sensor monitor and a motion sensor. The motion sensor communicates with the sensor monitor and includes an accelerometer, a control module, an emitting module, a power source, and a switch. The accelerometer senses the acceleration value of the motion sensor. When the control module determines that at least two acceleration values sensed continuously by the accelerometer respectively reach or exceed a predetermined value, the control module turns on the switch to control the power source to provide power to the emitting module, generates control signals, and controls the emitting module to emit the control signals to the sensor monitor to direct the sensor monitor to take action. | 07-05-2012 |
| 20120173886 | ELECTRONIC DEVICE WITH A FILE AUTHORIZATION MANAGEMENT FUNCTION AND METHOD THEREOF - An electronic device for managing file authorization is provided. The electronic device stores encrypted files. Each encrypted file presets a predetermined password. When receiving an operation signal of one of the encrypted file, the electronic device determines whether the operation signal matches the predetermined password of the selected file. The electronic device processes the file in response to the operation signal if the input matches the predetermined password of the selected file, and does not respond to the operation of the selected file if the input does not match the predetermined password of the selected file. | 07-05-2012 |
