Abstract: A control apparatus for controlling one or more functions of a controlled device includes a movement sensor operable to detect both a direction of movement and an amount of movement of the control apparatus, a microcontroller for receiving a signal corresponding to the direction and amount of movement and generating one or more corresponding control signals for controlling the controlled device, and a transmitter for transmitting the control signals to the controlled device. The control apparatus may include a position selectable control and a sensor coupled to the control to sense a position thereof. According to some implementations, the movement sensor may be used to control a direction of the controlled device, and the position selectable control may be used to control a speed of the controlled device.

Abstract: The invention relates to propellant compositions comprising a solid inorganic perchlorate oxidizing agent, a nitrogen-containing fuel, and a burn rate catalyst. Such compositions may be used as a propellant material, (e.g., in rocketry), a pyrotechnic material, an explosive material, a light generating material, a heat generating material, or a sound generating material.
