Abstract: The disclosure provides systems and methods for conducting and managing integrated laboratory experiments. The system includes a variety of laboratory instruments that are connected to conduct a large number of different types of experiments, and an interface for a user to design experiments and adjust parameters for the experiments. Given the integration, the system can further take data from related samples and instruments for determining or adjusting certain experimental parameters for optimized experimental efficiency and results.

Abstract: A speedometer capable of providing real-time speed signals, that can be combined with different functional devices and speed control units, to facilitate the automatic recording and controlling of the speed, thereby forming a multifunctional automatic monitoring and controlling device for vehicles. Photoelectric sensors are disposed in the conventional mechanical magnet-type speedometer, and a LED is mounted on the speed indicating needle shaft. The ON and OFF states of the LED can be controlled by a signal from within or from external of the vehicle. The output of the photosensors are connected to a multichannel photoelectric converter.
