Abstract: An ultrasonic system and an ultrasonic method with adaptive overflow and gain control are provided. The present disclosure uses two-stage gain controls to improve the signal-to-noise ratio (SNR) and to achieve the correct analysis of results. The first stage adopts an analog gain, and monitors whether the signal may overflow or its signal strength is too weak, and adjusts the gain value as large as possible, without causing overflow in order to improve the SNR. The second stage adopts a digital gain. In the second stage, all the amplified gain-containing data adjusted in the first stage are received, and an amplified gain-containing data segment is sequentially retrieved in chronological order, and the amplified gain-containing data segment is converted into a same-gain data segment having the same gain. Finally, the same-gain data segment is provided to a Doppler signal analyzer for analysis.

Abstract: An antenna apparatus and a method for controlling an antenna array are provided. The method includes the following steps. A plurality of selectable antenna configurations is provided for a directional service. One of the antenna configurations is selected for an antenna element of the antenna array according to a service criterion. The antenna apparatus includes an antenna array, a controller, and a switching unit. The antenna array includes a plurality of antenna elements. The controller is adapted to generate a control signal based on selecting one of a plurality of antenna configurations according to a service criterion for an antenna element to provide a directional service. The switching unit is adapted to configure each of the antenna elements according to the control signal.
