    Abstract: A permanent magnet harmonic motor comprises: a rotor mechanism (1) with several permanent magnets (2) disposed thereon, a stator mechanism (3) fitted with the rotor mechanism (1), and a support mechanism (8) with a bearing assembly (10) disposed thereon. The rotor mechanism (1) is connected to the support mechanism (8) through the bearing assembly (10); magnetic regulating teeth (4) are circumferentially formed at a part of the stator mechanism (3) close to the rotor mechanism (1), and distributed windings (6) are arranged on the magnetic regulating teeth (4). The number of parts in the permanent magnet harmonic motor is reduced; the permanent magnet harmonic motor has a simpler structure, and an assembly process is simple. In addition, the weight of the whole motor is reduced, and the size of the motor is reduced, which facilitate the reduction in the unsprung mass of an electric vehicle, thereby improving the stability and riding comfort of the vehicle.

    Abstract: An ultrasonic imaging system for measuring elasticity of biological tissues, including a probe (10), an ultrasonic imaging device (310), a controlling and processing device (330), and a display device (350). The probe(10) includes a low frequency oscillating device (110) and an ultrasonic array transducer (130). The low frequency oscillating device (110) is configured for generating oscillation and forming shear waves propagating from a body surface to the biological tissues. The ultrasonic array transducer (130) is configured for emitting ultrasonic signals to the biological tissues and receiving ultrasonic echo signals reflected from the biological tissues. The ultrasonic imaging device (310), according to loaded imaging parameters, drives the ultrasonic array transducer (130) to emit the ultrasonic signal to the biological tissues, and receives and processes the ultrasonic echo signals from the ultrasonic array transducer (130). The controlling and processing device (330) controls the low frequency oscillating device (110) and the ultrasonic imaging device (310) to obtain a 2D ultrasonic image and elasticity information of the biological tissues. The display device (350) displays the 2D ultrasonic image and the elasticity information of the biological tissues. The 2D ultrasonic image and elasticity information of the biological tissues can be obtained at the same time, such that accuracy of clinical diagnosing is promoted. The low frequency oscillating device (110) and the ultrasonic array transducer (130) are independent, so the ultrasonic array transducer (130) will not move with the low frequency oscillating device (110), and there is no need to considerate displacement compensation. The probe (10) can locate accurately with the aid of the 2D ultrasonic image, such that convenience and accuracy is promoted in measuring elastic modulus and process difficulty is decreased.

The plurality of grooves serve as focal electrodes distributed uniformly, with smaller electrode sites and more recording points. The modified platinum dendrite structures increase the surface area, electrical performance, biocompatibility and service life of the microelectrode. Besides, creating virtual electrodes by current steering technique increases the number of stimuli received by microelectrode during use, and improves its resolution in applications.
