Abstract: Gas sensors are disclosed having an on-board, low-power data processor that uses multivariable gas classification and/or gas quantitation models to perform on-board data processing to resolve two or more gases in a fluid sample. To reduce computational complexity, the gas sensor utilizes low-power-consumption multivariable data analysis algorithms, inputs from available on-board sensors of ambient conditions, inputs representing contextual data, and/or excitation responses of a gas sensing material to select suitable gas classification and/or gas quantitation models. The data processor can then utilize these gas classification and quantitation models, in combination with measured dielectric responses of a gas sensing material of the gas sensor, to determine classifications and/or concentrations of two or more gases in a fluid sample, while consuming substantially less power than would be consumed if a global comprehensive model were used instead.

Abstract: A method of filtering streaming digital data in real time. The method including: (a) initializing and storing a set of m data elements and an associated set of m pointer data from 1 to m in sequence, m an integer greater than 2; (b) receiving in real time a first or next data element of a digital data stream of sequential data elements; (c) simultaneously with (b), replacing a stored data element associated with the pointer datum m with the received data element, changing the pointer datum of m to 1, and incrementing the value of all other pointer data by 1; (d) simultaneously with (b) sorting in order from a low to high all stored data elements; (e) simultaneously with (b), maintaining the association of pointer datum and data elements; (f) simultaneously with (b), filtering all stored data elements; and (g) repeating (b) through (f) multiple times.
