The description for the raspberry shake says it combines “a professional-grade vertical seismometer (called a geophone) digitizer, hyper-damper and computer.” I understand the purpose of all components except the hyper-damper. A google search only returns listings for the raspberry shake, and I didn’t find anything in previous forum posts. Can anyone shed some light on the purpose of a hyper-damper, or point out some relevant literature?
Thank you!
