Abstract: A system and method for monitoring biological parameters in freely moving animals that, in the illustrative embodiment, comprises a two-color optical measurement/recording system that is combined with a fluorescent protein reporter of cellular membrane potentials and a fluorescent protein that is insensitive to such cellular membrane potentials. The two wavelengths are used to un-mix physiological artifacts in recordings that occur in freely moving animals.

Abstract: An anti-rotation system for an elevator system that includes an elevator shaft, elevator suspension cables, and a mechanical room includes a hitch plate disposed on a floor of the mechanical room and at a top of the elevator shaft, a plurality of cable shackles, each cable shackle including a cable locking mechanism on a first end thereof configured to lock one of the elevator suspension cables and a threaded rod on a second end thereof configured to extend through the hitch plate from the elevator shaft to the mechanical room, and a plurality of anti-rotation devices, each anti-rotation device being fixed to the threaded rod of one of the plurality of cable shackles in the mechanical room, and each anti-rotation device being connected to at least one other anti-rotation device, whereby rotation of cable shackles is prevented.
