Abstract: A control system and method which automatically responds to a stalling motor due to a brush head binding or hanging event, and which automatically prevents backlash damage to the electronics when the brush head is freed from it's constraints.

Abstract: A method for improved controlling of a thermic infusion system having a one tubal segment and a thermal element to heat an infusion fluid carried within the tubal segment, and having at least one sensor positioned within the thermic infusion system comprising regulating energy provided to the sensor for a first period of time to sense a self-heating effect of the at least one sensor due to a dry tube; responsive to detecting a dry tube, preventing energizing the thermal element; responsive to detecting a non-dry tube, regulating energy provided to the sensor for a second period of time to sense a temperature of an infusion fluid carried within the at least one tubal segment.

Abstract: A method for determining spin of a projectile comprising generating an electromagnetic radar signal and transmitting the electromagnetic radar signal towards a projectile. Receiving a reflected electromagnetic radar signal from the projectile. Identifying a component of the reflected electromagnetic radar signal, and performing an autocorrelation process on the reflected electromagnetic radar signal using the component to generate an estimate of a spin of the projectile as a function of the autocorrelation process.

Abstract: A method for determining spin of a projectile is disclosed that includes generating an electromagnetic radar signal and transmitting the electromagnetic radar signal towards a projectile, receiving a reflected electromagnetic radar signal from the projectile and transforming the reflected electromagnetic radar signal from a time domain to a frequency domain to generate a frequency domain signal. A peak frequency component of the frequency domain signal is identified, shoulder frequencies adjacent to the peak frequency component in the frequency domain signal are identified, and an estimate of the spin of the projectile as a function of the shoulder frequencies is generated.
