To control the pan/tilt unit, the security operator uses a lever switch, joystick, or thumb trackball at the control console.
All task parameter sets are described as follows: active/inactive lever switch schedule, active lever response schedule, OLP response schedule (observing light duration), i.e., for the final training session, S30, the schedule was FT90s, VR10-20, OLP FR1 (15s).–20, OLP FR1 (15s).
"So we reasoned, if we can do that with a computer, could another brain do that?" The researchers first trained pairs of rats to solve a simple problem - pressing the correct lever when an indicator light above the lever switched on, to obtain a water sip.
The chain reaction begins when a ball rolls across a table and hits a lever, switching on a fan.
If the active lever switched location during the observing period, the light position switched correspondingly.
The active lever switched sides under an FT90s schedule [increased from FT60s in order to accommodate higher ratios of responding].
Only functional OLPs were sensitive to uncertain active lever switching, so uncertainty in this form may serve only to reset functional checking to a higher level, rather than promote non-functional checking.
First experimental results show that such bi-stable toggle-lever switches can be utilized for direct multimode fibre switching where a stroke of about 100 μm is needed.
The Console which contains a large number of buttons, joysticks, knobs, levers, switches, pedals, and patch-cords, each labelled with medical silliness (such as "Biological Clock" or "Yakovlevian Forcer").
These silicon chip-like devices, fabricated with the help of etching and vapour deposition techniques borrowed from the semiconductor industry, combine a variety of sensing functions with the ability to activate microscopic levers, switches, valves and pumps carved into their innards.
Overall, at higher VRmax, addition of lever-switch uncertainty significantly increased OLPs (Fig. 7a,b, FT vs. VT at VR 10 70, F 1,20) = 20.39, p < 0.001).
