China's Mars probe including an orbiter and a landing rover will be launched by 2020. A subsurface penetrating radar (SPR) instrument has been selected to be a part of the payload on the rover. The main scientific objective of the SPR is to characterize the thickness and sub-layer distribution of the Martian soil. The SPR consists of two channels. The low frequency channel of the SPR will provide...
An acceleration latching switch with integrated normally Open/Close paths is presented in this paper. Two arch trusses used as fracture parts of the normally-close path are connected in series to form the normally close path, which will be broken and latched by the latching mechanism to reach the open state once the input acceleration beyond threshold. Moreover, the normally-open path is consisted...
Unipolar switching scheme (USS) and bipolar switching scheme (BSS) are popular choices of switching techniques for most inverter applications. Ideally, the output waveform with USS has lower switching loss and harmonic distortion than that with BSS. However, due to the narrow pulses generated around the zero-crossing region, the practical output waveform with USS exhibits pulse-dropping phenomenon...
