Experiment on a test bench is one of the key points during the research and development of a transmission. This paper designs a new real-time dynamic test bench based on MATLAB/Simulink® for testing and developing a novel seamless two-speed automatic mechanical transmission (AMT) for electric vehicles (EVs). Structure of the transmission allowing seamless shifting between two gears is also proposed. According to the transmission structure and the real-time testing requirements, hardware components and software system of the test bench are designed. A real-time executable and flexible model of the EV that is more suitable for hardware-in-the-loop (HIL) simulation, is built to run on Simulink Real-Time platform. The EV model is combined with two induction motors adopting direct torque control (DTC) technique to emulate the dynamic driving conditions of the transmission on the test bench. Simulation and experimental results show that the test bench responds well to the real-time dynamic requirements and it is very useful for testing and developing the proposed transmission.

Gesture Spotting

In this paper, a real-time dynamic hand gesture recognition system with gesture spotting function is proposed. In the proposed system, input video frames are converted to feature vectors, and they are used to form a posture sequence vector that represents the input gesture. Then, gesture identification and gesture spotting are carried out in the self-organizing map (SOM)-Hebb classifier. The gesture spotting function detects the end of the gesture by using the vector distance between the posture sequence vector and the winner neuron’s weight vector. The proposed gesture recognition method was tested by simulation and real-time gesture recognition experiment. Results revealed that the system could recognize nine types of gesture with an accuracy of 96.6%, and it successfully outputted the recognition result at the end of gesture using the spotting result.

Holographic Display

In this paper, we studied the holographic properties of liquid crystal (LC) thin film doped with carbon dots (CDs) which can be used as real-time holographic display screen. The maximum value of diffraction efficiency can reach up to 30% by using a low applied electric field 0.2 V/μm. Holograms in the LC film can be dynamically formed and self-erased. The hologram build-up time and the hologram self-erasure time in the material is fast enough to realize video refresh rate. In addition, the forming process of hologram was studied. The holographic diffraction efficiency was measured depending on the intensity of recording light, applied electric field, the intensity of readout light, and readout light polarization direction. Triple enhancement of the diffraction efficiency value by the modulation of voltage under the condition of low recording energy is presented. Therefore, we develop an easy way to obtain real-time dynamic holographic red, green and blue displays with high diffraction efficiency, which allow the LC film doped with CDs to be used as a holographic 3D display screen.
