Abstract: An electrochemical gas sensor including a substrate defining an opening therethrough, a sensing electrode connected to a first surface of the substrate and adjacent a first end of the opening, a diffusion barrier connected to the sensing electrode, a counter electrode adjacent a second end of the opening, and an electrolyte located in the opening between the sensing electrode and the counter electrode.

Abstract: The present invention is directed to an electrochemical gas sensor network. The network includes a gas sensor for receiving a gas and for generating a target gas concentration signal. The gas sensor has an output terminal for providing an output signal that is a product of the target gas concentration signal and a first transfer function. The network also includes a compensation circuit having an input terminal connected to the output terminal of the gas sensor. The compensation circuit also has an output terminal which provides an output signal that is a product of the output signal from the gas sensor and a second transfer function. The second transfer function is approximately an inverse of the first transfer function. The present invention also contemplates a method of compensating for the attenuation of a high frequency component of an output signal of a gas sensor.

Abstract: A saturable inductor switch. The switch includes a number of spaced cores disposed adjacent one another with each core being made of ferromagnetic material. An insulative layer is disposed about each core and each core has an electrical winding about the insulative layer for that core. Each winding has a first end and a second end and is electrically connected to its respective core intermediate the ends. The windings are connected in series. All the cores have substantially the same size and shape, and all windings have substantially the same number of turns.
