This alternative to time-of-flight LiDAR has unique complexities and distinct attributes. When engineers hear the phrase LiDAR, an acronym for Light Detection and Ranging, they generally think of time ...
Gearboxes are commonly used in rotary machines. Reliable fault diagnostics in gearboxes is of great importance to industries to improve production quality and reduce maintenance costs. In this paper, ...
Abstract: High-frequency voltage signal injection (HFSI) is a sensorless control strategy for internal permanent magnet synchronous motors (IPMSMs) at zero and low speeds. A reasonable demodulation ...
In this paper, we proposed a cooperative beamforming ALOHA (CBA) scheme based on linearly constrained minimum variance criterion for low Earth orbit satellite (LEO) IoT networks to solve the problem ...
Abstract: This paper investigates the performance of two novel half-switching frequency signal injection (HSFSI) demodulation algorithms for encoderless field-oriented control (FOC) of permanent ...
Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...
Brain–computer interface (BCI) technology provides a new communication channel. However, current applications have been severely limited by low communication speed. This study reports a noninvasive ...
