Abstract: The present disclosure relates to detecting the use of fake voice command to activate microphones of smart devices. In one embodiment, sound characteristics associated with an audio signal from a microphone of smart device may be compared with other microphones of the smart device in order to detect fake voice commands. In another embodiment, sound characteristics associated with the audio signal from the microphone may be compared with a threshold range of stored sound characteristics in order to detect fake voice commands. In some embodiments, a controller may triangulate a position associated with a source of a sound in order to detect a fake voice command. In a further embodiment, a controller may verify that a user or associated electronic device are near a smart device to authorize a voice command.

Abstract: A durable, modular, adaptive containment system, which has a composite composition comprised of wood fibers embedded in a polymeric matrix, the system being suitable for holding soil and plants, and which is comprised of rails, preferably of rectangular cross-section, each of said rails being joined by means of a T-shaped tenon along one of its ends and a complementary T-shaped channel on the side of the rail near its other end, or which is comprised of a connector having T-shaped channels so that when four rails, each of which has a T-shaped tenon on each end, pairs of which are of equal length, are joined by inserting the T-shaped tenons of each rail into a complementary T-shaped channel on a connector, a rectangular containment system is formed.

Abstract: A snow deflection system for a snowplow includes an arcuate foil and a preferred belt. Both the foil and the belt are attached to the moldboard of the plow so that the preferred belt keeps the plowed snow close enough to the moldboard to allow the arcuate foil to direct the flow of snow and air, which blows over the top of the moldboard, down and away from the plow vehicle.

Abstract: A carburetor includes a pendulum metering element delivering fuel to a hollow throttle shaft from a fuel metering chamber by means of a graduated depth groove in the chamber wall which is engaged by a spring urged jet member carried by the pendulum element and offering constant fluid-tight engagement with the chamber groove with minimum frictional drag. Stability of both fuel metering/vaporization throughout variations in temperature is significantly enhanced by formation of the carburetor body from a machined block of a metal selected for its ideal combined capability of heat storage and dissipation. An improved sealing assembly between a float and fuel chamber and the metering chamber coupled with a regulator device insuring a constant fuel inlet pressure enhances this stability of operation.
