An embodiment of the present invention provides low latency, high capacity rings by combining a low latency memory with a higher latency memory. The conduit is bent and oriented such that the open end is tangential to the radius of crankshaft rotation and faces in the direction of rotation. The rapid cooling of the biological materials is achieved by precisely controlling and adjusting the temperature of the cryogen being introduced to the system as a function of time. Then, the movement amount for the pointer is decided in accordance with the movement amount for the knob display. The present invention also relates to a corresponding method of making a wiper system in accordance with the above description.
