TL;DR: In this paper, the authors describe a musical instrument consisting of a portable transmitter unit, a receiver unit, and a standard or modified piano, electronic organ, or other keyboard musical device.
Abstract: A musical instrument which comprises (i) a portable transmitter unit, (ii) a receiver unit, and (iii) a standard or modified piano, electronic organ, or other keyboard musical device. The transmitter unit has sixty keys, each of which corresponds to a key of the remote piano, organ, or other keyboard musical device, and also has eight auxiliary switches for controlling the receiver and auxiliary functions of the musical device to be remotely played. The transmitter includes electronic circuitry which scans the keys and auxiliary switches, and transmits an FM signal modulated by a serial digital pulse train identifying the transmitter keys which are depressed and the auxiliary switches which have been actuated. The receiver unit decodes the transmitted pulse train, eliminates erroneous data, and generates output signals to control the corresponding keys and auxiliary functions. The transmitter circuitry contains means for incorporating features in the digital code utilized which provide increased noise immunity and alleviate the need for the receiver to handle very low frequencies of the demodulated signal.

TL;DR: In this paper, a T.V. remote control system includes a wireless hand control and a control unit easily and quickly coupled to any television, which contains a varactor tunable frequency converter to convert selected signals to an unused channel.
Abstract: A T.V. remote control system includes a wireless hand control and a control unit easily and quickly coupled to any television. The control unit contains a varactor tunable frequency converter to convert selected signals to an unused channel responsive to the application of respective tuning voltages. Channel sequencing is possible directly or by remote control in addition to skipping of unused channels.

TL;DR: In this paper, the emergency electric current generator is used for small aircraft, driven by the air flow which drives a bladed wheel coupled to a generator, which provides power for the instruments on board the aircraft, and can be used in gliders as a constant power supply for wireless apparatus.
Abstract: The emergency electric current generator is used for small aircraft. The emergency generator is driven by the air flow which drives a bladed wheel coupled to a generator. In normal conditions this generator is covered with a streamlined cover, and provides power for the instruments on board the aircraft. It can be used in gliders as a constant power supply for wireless apparatus. The bladed wheel (5) can be driven from its rest position within the aircraft skin (19) into the operating position outside this skin. The channel is normally closed by the plate (18) which is moved out together with the bladed wheel rotor.
