Stimulation control apparatus for an ink jet recorder
TL;DR: In this paper, a drive circuit for a stimulation transducer suppresses generation of satellite drops in an ink jet recorder, which is an oscillator which tracks the resonant frequency of the stimulation transducers.
Patent
High speed frequency shift keyed transmission system
TL;DR: In this paper, a frequency shift keyed data transmission (FSK) system was proposed, which utilizes a transmitter comprising an oscillator for producing output voltage pulses whose repetition rate is governed by the time constant of an associated RC circuit, a key switch for altering the resistance of the associated circuit-thereby altering the pulse repetition rate-and a conversion circuit for converting the pulses into sinusoidal output waves having a frequency proportional to the pulse rate.
Patent
Temperature to frequency converter
TL;DR: A temperature to frequency converter as discussed by the authors consists of two temperature detectors having an electrical characteristic, such as resistance, that varies proportionally with sensed temperature, connected into an oscillator circuit that provides an electrical signal output having a frequency inversely proportional to sensed temperature.
Patent
Apparatus for temperature measurement
TL;DR: In this article, an improved apparatus for temperature measurement which minimizes sensing element self-heating error and instrument ambient heating error when used as an oceanographic thermometer includes a frequency-selective network having a thermistor as a temperature sensing element thereof.
Patent
AM Radio receiver
TL;DR: In this paper, the output of the harmonic oscillation circuit is utilized for the AM demodulation of the received signal, whereby image-frequency components as in the superheterodyne system are not detected and only the tuned-frequency component is detected, thus preventing the occurrence of radio interference.
