In another aspect, the stored cold temperature storage medium is mixed with the ambient fluid prior to heat rejection from the thermodynamic cycle to the ambient fluid.

the ambient fluid (air) flowing along the machine".

According to the inventive method, the ambient fluid (4) including the biological particle (5) is introduced into the receiving compartment so that a surface section of the electrode (1a) is brought into contact with the ambient fluid (4).

the ambient fluid (air) flowing along the machine".

An inner layer (22) of the co-layered cover member (18) is permeable to the ambient fluid.

the ambient fluid (air) flowing along the machine".

The system and method also effectively reduce errors induced by temperature and humidity drifts in the ambient, and the sampled, fluid.

The jet (44) is guided by the wall and the exterior side of the jet interacts with ambient fluid.

In operation, the fluid flow of this embodiment of the cooling module comprises a synthetic jet stream and ambient fluid entrained into the channel by the synthetic jet stream.

Also, a lamp comprising means (74) for creating flow of ambient fluid.

A flow channel for ambient fluid, which channel is sealed from the internally circulating fluid, may be provided for removing heat from a cooling unit of the ECU.

Systems and methods configured to control ambient fluid flow for increased energy extraction using a turbine are disclosed.

For the flow of the ambient fluid, which only feels this skin, the result is the same.

The invention is also applicable to the detection of other characteristics of ambient fluid, such as temperature or the presence of a particular gas or vapour.

Sensing means for sensing speed and direction of movement of a body (10) movable in an ambient fluid in a direction transverse to the longitudinal axis (11).
