Abstract: A micro-viscosity sensor for measuring the viscosity of a lubricant. The micro-viscosity sensor including at least one finger-like element or an array of finger-like elements vertically extending from the surface of a semiconductor base, the at least one finger-like element being oscillated at a desired frequency. The power required to oscillate the at least one-finger-like element is monitored because the power required is a function of the viscosity of the lubricant. The sensor also includes a temperature detector, wherein the thermal conductivity of the temperature detector varies in correspondence with the temperature of the lubricant. A first set of electrical contacts provides for electrical connection to the at least one finger-like element; and a second set of electrical contacts provides for electrical connection to the temperature detector.

Abstract: A system for training a neural network to synthesize vibration data relating to the operation of a machine. The system includes a first sensor operatively coupleable to the machine, the first sensor adapted to obtain at least one vibration signal relating to the operation of the machine. The system further includes a second sensor operatively coupleable to a power lead of the machine, the second sensor adapted to obtain at least one current signal relating to the operation of a machine. Additionally, the system includes a neural network operatively coupleable to the second sensor, the neural network being trainable to generate at least one synthesized vibration signal from the current signal, wherein the synthesized vibration signal is substantially equivalent to the vibration signal obtained from the first sensor.
