Abstract: In indoor acoustic localization, mobile devices must preprocess audio signals with a filter. Traditional filters, such as FIR and IIR filters, designed for fixed frequency ranges, struggle ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

As an important part of active sonar, transmitted signals have a great influence on the performance of ocean exploration, however, in the actual environment, due to the existence of the Doppler ...

In this manuscript, the authors used in vivo long-term tip recordings of the long trichoid sensilla of male hawkmoths to analyze spontaneous spiking activity indicative of the ORNs' endogenous ...

Wi-Fi is no longer just for internet access. A new system named WhoFi uses how the human body alters radio waves to identify a person with up to 95.5 percent rank 1 accuracy, according to a new study.
