Currently, gesture recognition based on electric-field detection technology has received extensive attention, which is mostly used to recognize the position and the movement of the hand, and rarely used for identification of specific gestures. A non-contact gesture-recognition technology based on the alternating electric-field detection scheme is proposed, which can recognize static gestures in different states and dynamic gestures. The influence of the hand on the detection system is analyzed from the principle of electric-field detection. A simulation model of the system is established to investigate the charge density on the hand surface and the potential change of the sensing electrodes. According to the simulation results, the system structure is improved, and the signal-processing circuit is designed to collect the signal of sensing electrodes. By collecting a large amount of data from different operators, the tree-model recognition algorithm is designed and a gesture-recognition experiment is implemented. The results show that the gesture-recognition correct rate is over 90%. With advantages of high response speed, low cost, small volume, and immunity to the surrounding environment, the system could be assembled on a robot that communicates with operators.

Traditional tapered waveguide devices are limited by their power efficiency and produce unstable plasmas and small reaction zones. To overcome these drawbacks, a multi-ridge field compressed reactor operating at a frequency of 2.45 GHz is designed in this paper. The finite element method is applied to numerically compute its properties. A coupling model for the multiple physical fields is introduced to simulate the transient processes of a microwave argon plasma. Experiments with different flow rates and power settings are performed. This novel device can both sustain a long-length plasma and increase the power transfer efficiency from microwave to air and to the argon plasma, respectively, to 97.4% and 95.2%. Moreover, both devices are used to process the degradation of ethanol and benzene. The removal efficiencies are increased by 38.8% and 73.8% for ethanol and benzene, respectively, in the novel waveguide compared with the tapered waveguide.
