An apparatus is provided that is configured as or otherwise includes an axial flux electric machine. This axial flux electric machine includes a plurality of rotors, a plurality of stators and a shaft rotatable about an axis. The rotors are disposed axially along the axis and are mounted to the shaft. Each of the rotors includes a plurality of rotor magnets. The stators are axially interspersed with the rotors along the axis. Each of the stators includes a plurality of stator magnets. The stator magnets of a first of the stators are arranged asymmetrically about the axis.

A medical fluid probe includes a heat spreader structure that defines therein a fluid chamber that is in fluid communication with an external environment around the probe, and a thermal energy source in thermal communication with the heat spreader structure. The heat spreader structure functions as both temperature-control elements and structural elements. A variety of separate structure elements, such as the heat pipes, may combine to form the heat spreader structure. The thermal energy source may be used to maintain the temperature of the heat spreader structure, such as by heating and/or cooling the heater spreader structure.

Medical fluid probe with heat spreader structure and thermal energy source

A fluid probe includes a heat spreader structure that defines therein a fluid chamber that is in fluid communication with an external environment of the probe, and a thermal energy source in thermal communication with the heat spreader structure. The heat spreader structure may be made from heat pipes, which function as both temperature-control elements and structural elements. The thermal coupling of the heat spreader structure and the thermal energy source may be used to transfer heat between the two, heating, cooling, and/or maintaining temperature of the heat spreader structure. The fluid probe may have any of a variety of uses, for example being a pitot tube for an aircraft, a fluid sampling device, a medical device, or a device for injecting a fluid.
