203 and thermocouples 207 are thin in nature generally a few microns u03bcm the heater 206 will not block the ion jet stream 224 flow in the lateral direction at rest i e when the device 200 is neither spinning nor linearly moving the positive and negative thermocouples 208 210 should sense a same temperature thus a difference between their respective signals tcp 1 tcm 1 is zero as the ion jet stream 224 is traveling in a straight direction in this case along the x axis and impinging equally on the thermocouples thus the output signal rotation u00f8 shown in fig4 would be zero in a situation where the device 200 is rotating as shown in fig2 c i e rotating about the z axis which in fig2 c is coming up out of the drawing the ion jet stream 224 will be skewed toward either the positive thermocouple 208 or the negative thermocouple 210 as a result there will be a temperature difference between the positive and negative thermocouples 208 210 resulting in a difference between the respective output signals tcp 1 tcm 1 and the value rotation u00f8 will be greater or less than zero depending upon the direction of spin the gyroscope 200 shown in fig2 a 2c however is subject to interference in the output signal rotation u00f8 due to linear acceleration that is when the device 200 is accelerating along a direction that.
