Abstract: A method of controlling the temperature of a liquid held within a reaction container in a chamber of a thermal cycling apparatus, the method including determining a sensed chamber temperature from a temperature sensor in the chamber, determining an air temperature using the sensed chamber temperature, determining a liquid temperature using the air temperature and selectively heating or cooling air in the chamber in accordance with the liquid temperature.

Abstract: A memory management method (44) for a memory having program contexts including an active program context in an active region and inactive program contexts in an inactive region. Each program context has a first and a second part. Second parts of the active program context are separated by a contiguous memory space comprising a free memory block and a common data parameter store. In operation, the method swaps (50) a location of the second part of the active program context with the contiguous memory. A swapping step (54) is then effected to swap a location of a the inactive program context with the active program context and any program context therebetween. Another swapping step (56) is then effected to swap a location of a second part of the inactive program context with the contiguous memory space, after which the inactive program context becomes currently active.
