Abstract: A method to measure sound-producing behaviors of a subject with a power- and bandwidth-limited electronic device that includes a processor includes measuring, by a microphone communicatively coupled to the processor, sound in a vicinity of the subject to generate an audio data signal that represents the sound. The method also includes measuring, by at least one second sensor communicatively coupled to the processor, at least one parameter other than sound to generate at least a second data signal that represents the at least one parameter other than sound. The method also includes detecting one or more sound-producing behaviors of the subject based on: both the audio data signal and the second data signal; or information derived from both the audio data signal and the second data signal.

Abstract: An adjustable stand includes a leg, a first member secured to the leg, a second member adjustably secured to said first member, and a support member for holding items on the stand, the support member is secured to the second member. A first adjustment mechanism is coupled between the first member and the second member. Movement of the first adjustment mechanism shifts the position of said second member relative to said first member thereby raising or lowering said support member. A retention member is secured between the first member and the second member, the retention member securing the first member to the second member, while allowing at least limited relative movement relative to the first member. A first adjustment mechanism includes a nut threaded on a shaft, bearing against the first tubular member and an anti-rotation lock secured to the shaft and coupled to the first tubular member.

Abstract: There is disclosed an internal combustion (V-8) engine having an improved form of cylinder head and intake manifold for augmented combustion air flow and improved fuel mixing wherein the intake chamber immediately upstream of the intake valve is provided with two inlet ducts rather than the usual one inlet duct. The primary inlet duct may be conventional; the secondary inlet duct branches off in a direction more nearly parallel to the central axis of the cylinder and preferably connects to an inlet pipe which draws air through an independent air filter. The secondary inlet duct is provided with its own butterfly valve which can be independently controlled either automatically or manually and may be provided with a fuel injector. Secondary inlet ducts of the system can be attached on the outside to the inlet stacks (for injected engines), to an air breather base (on carburated engines), or to draw filtered air from the atmosphere directly into the system.
