Soaps Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Types of Soap: The type of fatty acid and length of the carbon chain determines the unique properties of various soaps.
However, in order to gain acceptance as a method of stress. management in the workplace, wearable sensors must be. minimally obtrusive, so that workers can perform their tasks. with complete freedom, and inconspicuous, to avoid. anxieties associated with wearing medical devices in public.
Two Types of Sensor. There are 2 types of each of these sensors. The most common is what I'll call a voltage type MAP or MAF. The voltage type communicates to the ECU by giving it a voltage, and this voltage tells the ECU what the MAP's current pressure reading is, or the MAF's current volume of air flow. The ECU gives a control voltage to the sensor of 5 volts.
