An Underground Pumped Hydro Storage system may comprise a substrate, a large water-fillable bag, and an overburden causing pressure in the bag. The overburden may have nonuniformities of composition or dimension. Such nonuniformities may locally make overburden more flowable or gentle to the bag, at regions of relatively high shape change or flow during a cycle. Such nonuniformities may help prevent the overburden from freezing up in cold weather, or may enable a controlled progression of bag shapes. The overburden may have an irrigation hose buried in it. The bag edge joint may have any of various features that provide for a transition of local bending and load distribution near the joint between the bag upper and lower layers. An antechamber may be provided for access to the bag interior for robotic inspection or maintenance. The system may be deployed near a dam on a river.

An electronic accelerometer is used to generate an acceleration signal for a passenger restraint system in a motor vehicle. The electrical signal is processed by emulating an electromechanical sensor to detect crashes. The electrical signal may also be differentiated to obtain a jerk signal also used to detect abnormal accelerations.
