摘要:
A vehicle platoon system comprises a trajectory module, an operation module and a control module. The trajectory module obtains and records a first data from a driving condition of the leading vehicle to establish a movement trajectory. The operation module obtains a second data and receives the first data to enable the following vehicle to move along or on the movement trajectory and carry out the driving condition of the leading vehicle. The control module measures an interval distance between the leading vehicle and the following vehicle to adjust a speed of at least one of the leading vehicle and the following vehicle so as to maintain the interval distance within a predetermined range. A vehicle platooning method is also provided.

A monitor and a method of displaying a plurality of pixels on a displaying device are disclosed. The monitor includes a displaying device including a controlling module and a displaying panel electrically connected to the controlling module. The controlling module displaying the plurality of pixels on the displaying device partially according to a brightness adjustment relation and partially according to an original gray level-brightness relation. Therefore, the invention can adjust input images only in partial gray levels, not all gray levels, by a user's request, for example making dark portions become bright or making bright portions become dark, especially for games.

A variable-delay-time control system for a motor is provided. The system includes a control unit, a driving unit, and a motor. The control unit is used to output at least one control signal according to at least one predetermined signal, and the control signal has a variable delay time. The driving unit is connected to the control unit, and is used to receive the control signal and generate a driving signal. The motor is connected to the driving unit, and conduction time of the motor is controlled according to the driving signal and the variable delay time. With the variable-delay-time control system of the present invention, the delay time of the control signal is variable, so the motor can operate at a high efficiency (for example, at a reduced current). Moreover, as the variable-delay time can be adjusted according to the predetermined signal, the motor can operate at a high efficiency in different operating states, thus improving the overall efficiency of the motor.

A positioning method for obtaining position where a light pen is in contact with a display device at a to-be-positioned spot is provided. The display device includes display areas, corresponding with positioning coding patterns of a built-in positioning frame. The positioning method includes the following steps. Firstly, a positive positioning frame and a negative positioning frame are obtained according to the built-in positioning frame. Next, the positive and the negative positioning frames are respectively added on first original video frames to respectively generate first frame displayed in first frame time and second frame displayed in second frame time. Then the light pen obtains first selected image and second selected image from the first and the second frames respectively. After that, a to-be-positioned pattern is obtained by subtracting the second selected image from the first selected image and a coordinate position of the to-be-positioned spot is obtained.

A signal transfer system. A first device operates with a first voltage and outputs a first signal and a second signal. A protection circuit receives the first and second signals and outputs the first and second signals when the first voltage is greater than or equal to a predetermined voltage, and provides a third signal and a fourth signal when the first voltage is smaller than the predetermined voltage. A delay circuit delays the second and fourth signals to generate a first delay signal and a second delay signal, respectively. A second device operates with the first signal and the first delay signal when the first voltage is greater than or equal to the predetermined voltage, and operates with the third signal and the second delay signal when the first voltage is smaller than the predetermined voltage.
