Abstract: An antenna comprising the primary and secondary radiation structures and impedance-matching circuit are disposed in a collinear configuration with single port. The impedance-matching circuit can expand the antenna bandwidth in plural frequency bands with low VSWR. The transmission line between the RF connector and radiation structures are frictional wrapped by ferrite toroid cores, which improves the antenna in term of electrical stability. This also decreases the antenna sensitivity to the ground plane.

Abstract: A portable blowing device includes a body and fans arranged in the body. Air channels are arranged in the body and extend in the length direction of the body to allow airflow to pass through. Wind shields are arranged in the air channels, and a periphery of the wind shield is closely connected with a side wall of the air channel so that a sub-air channel is formed between the wind shield and the side wall of the air channel. Air outlets are formed in the side wall for communicating with outside and the sub-air channel, and airflow generated by the fan can enter the sub-air channel and then exits the air outlets. Because of the reduced volume of the sub-air channel, the airflow is concentrated after entering the sub-air channel, and airflow exiting the air outlets is strengthened, so that the cooling effect and the user experience are improved.

Abstract: The present disclosure discloses a control method for medical probe, an imaging method, and an ultrasound system. The control method includes: determining, for one emission, a delay correspondence matching a deflection angle; triggering the transducer to emit scanning line beams with the deflection angle according to the delay correspondence, so that scanning line beams emitted by array elements included in the transducer are focused on one focus in one emission, where scanning line beams with the same deflection angle are emitted based on the same delay correspondence. In the present disclosure, the transducer is triggered to emit scanning line beams with a deflection angle by sharing a delay correspondence, which can reduce a number of delay correspondences stored and save storage space, and there is no need to re-calculate an emission delay time of each array element based on the focus positions, which can improve the emission efficiency.

Abstract: An active GNSS splitter module is integrated into a GNSS and WIFI combination antenna to provide four equal GNSS outputs. Different components of this antenna have been optimally placed in the limited available space under a low-profile radome to minimize the mutual effects on the radiation pattern of the antennas. The special compact design of the splitter board allows it to be effectively shielded to mitigate the unintended couplings between the GNSS antenna and the splitter itself. The splitter has an internal amplifier to compensate for the loss of split and output cables. All GNSS output ports are DC pass and therefore the required DC power for the GNSS antenna can be supplied through any of these ports. The splitter is equipped with a DC select circuit which monitors all DC inputs and selects one of them to power the GNSS antenna and splitter itself.

Abstract: In one embodiment, an ultrasound imaging system is configured to receive a set of ultrasound images of a target anatomical region. The set of ultrasound images is combined to create a composite tissue frame. The ultrasound imaging system determines whether an interventional instrument is present within the ultrasound images based on a set of trained classification algorithms based on the set of ultrasound images and the composite tissue frame. If an interventional instrument is detected, the ultrasound imaging system further determines whether an additional ultrasound frame should be captured to image the interventional instrument, and the steer angle to be used for the additional ultrasound image. The ultrasound imaging system determines a linear structure corresponding to the interventional instrument, and creates a blended image showing the interventional instrument and the composite tissue frame.
