Abstract: Disclosed is an apparatus and method for operating a gliding parachute/kite. The gliding parachute/kite has a wing with a flexible material, and a set of suspension lines adapted for coupling a load to the wing, such that the coupling is configurable in any one of a plurality of possible states based on relative lengths of the suspension lines. In some implementations, the possible states include a first state enabling gliding in a first direction, and a second state enabling gliding in a second direction that is opposite to the first direction. Reversing direction is possible with the first and second states. Additionally, or alternatively, the possible states include a spinning state enabling spinning of the gliding parachute/kite. Adjusting a rate of decent is possible with the spinning. Reversing direction and/or spinning operations can be used to improve control of trajectory.

Abstract: A relaxation oscillator is formed by a Schmitt trigger circuit and an operational integrator circuit interconnected to form an oscillatory feedback loop. A diode switching network is constructed to receive a plural-bit digital input signal and to modify a circuit parameter in the oscillator feedback loop to adjust the frequency of oscillation in accordance with the coding of the digital input signal. An active low-pass filter circuit is connected to the output of the operational integrator circuit and supplies a sinusoidal tone signal to an output circuit. A switching circuit is responsive to the digital input signal for disabling the output circuit except during the occurrence of predetermined digital code values.

Abstract: There is disclosed a tone detector system which is particularly useful in communications systems for detecting audio-frequency signalling tones transmitted from one station to another. The disclosed tone detector system includes an amplifier followed by a limiter. The limiter drives a pair of signal channels each of which includes a tuned amplifier followed by a tone-to-digital converter. The tuned amplifier in each channel is provided with a pair of frequency selective filters, one or the other of which is used depending on the operating mode of the communications equipment. Interlock circuitry cross couples the outputs of the two tone-to-digital converters so that a tone signal indicative digital output signal can appear at the output of only one of the tone signal channels at any given instant.
