Indeed, there is no "sport" button on the centre console, and no tachometer amid the gauge cluster (counting revolutions per minute is so… mechanical).
At 10 p.m., they rode back and forth along the same stretch to calibrate the measuring devices on their bikes, which count revolutions of the wheel.
At eight weeks of age, four C57L/J and four C3H/HeJ mice (Jackson Labs, Bar Harbor, ME) were housed individually in cages with a 450 mm circumference solid surface running wheel (Ware Manufacturing, Phoenix, AZ) interfaced with a magnetic sensor and computer odometer (Sigma Sport BC600, St. Charles, IL) that counted revolutions of the running wheel and total time the mouse ran.
Even the thought of counting the revolutions of a spinning top is enough to leave one's head, well, spinning.
Animals in the voluntary exercise group were housed individually in a cage with a running wheel assembly (Respironics) connected to a switch that counted each revolution of the wheel and were recorded daily for 3 weeks.
Mouse running wheels were monitored with magnetic switches, a computer data acquisition system, and software to continuously count wheel revolutions occurring during 1-minute intervals.
This implies very long inter-orbital maneuvers counting many hundreds of revolutions.
But they have been rare enough for today's upsurge to count as a revolution in thinking about development.
The government held about $30 billion before the January revolution, counted about $22 billion in October and projects $15 billion by the end of next month.
In such a notoriously inert organisation, this counts as revolution.
In this way, each axis was equipped with an E5 optical rotary encoder (US Digital, Vancouver, Washington) allowing for a resolution of 1000 counts per revolution.
