Systems and methods for real-time signal validation are disclosed. The device can be a ventilator or a neuroelectrical stimulation device. This invention makes use of an inner can top composed essentially of niobium, which, under the compression pressure of an ultra high pressure press, bonds to a molybdenum disk, thereby providing improved tensile strength, abrasion resistance, bonding strength, as well as improved control over the cutting surface flatness. The SIC may be disabled when the output power of the transmitter is at a level below a predetermined threshold.
