Abstract: Embodiments include but are not limited to apparatuses and systems including a field-effect transistor switch. A field-effect transistor switch may include a first field plate coupled with a gate electrode, the first field plate disposed substantially equidistant from a source electrode and a drain electrode. The field-effect transistor switch may also include a second field plate proximately disposed to the first field plate and disposed substantially equidistant from the source electrode and the drain electrode. The first and second field plates may be configured to reduce an electric field between the source electrode and the gate electrode and between the drain electrode and the gate electrode.

Abstract: Simple compact apparatus for artificial resuscitation which avoids mouth-to-mouth contact. The apparatus enables a person to force exhaled air from his lungs into the lungs of a victim without mouth-to-mouth contact, the air flow being controlled by a flutter valve, so that air flows only from the person to the patient, with any fluid exhaled by the patient being by-passed around the valve and through appropriate outlets to the atmosphere.

Abstract: Generally, and in one form of the invention, a method is disclosed for terminating third harmonic frequency of a transistor amplifier comprising: determining the magnitude of the susceptance at the third harmonic frequency of initial circuitry, 41, 43, and 45, attached to the output of a transistor 39, wherein the initial circuitry has no third harmonic termination; determining whether the susceptance of the circuitry presented to the output of the transistor 39 is capacitive or inductive at the third harmonic frequency; and adding a compensating parallel susceptance 60 to the output of the transistor 39 that is substantially equal in magnitude to the susceptance of the circuitry attached to the output of the transistor 39, but capacitive if the susceptance of the circuitry presented to the output of the transistor 39 is inductive, or inductive if the susceptance presented to the output of the transistor 39 is capacitive, whereby the imaginary part of the susceptance of the total circuitry attached to the out

Abstract: Generally, and in one form of the invention, a bias circuit for a transistor amplifier comprising a nonlinear element which limits current flow in a transistor, whereby the output-signal amplitude of the transistor is limited and the transistor is protected from exceeding a maximum current level, is disclosed. In another form of the invention, a bias circuit for a transistor amplifier comprising a nonlinear element 44 which limits current flow through a base terminal of a bipolar transistor 48, whereby the output-signal amplitude of the bipolar transistor 48 is limited and current flow through a collector or an emitter terminal of the transistor 48 is prevented from exceeding a maximum safe level, is disclosed.
