| Number | Title | Issue Date |
| 7200502 | Dual connection power line parameter analysis method and system A method and apparatus is disclosed for determining the power line parameters of a system. Specifically, there is provided a method comprising perturbing a voltage waveform through a first connection, measuring a characteristic of the perturbation through a second c... | 04/03/2007 |
| 5661442 | Amplitude control system having parallel integrating signal paths An amplitude control system uses a pair of parallel integrators to rapidly adjust the amplitude of a test signal between two precisely determined power levels in an RF signal generator. The amplitude control system initializes a first power level by switc... | 08/26/1997 |
| 5144299 | Telemetry power carrier pulse encoder A telemetry system for use in controlling the operation of sensors configured on a rotating blade of a gas turbine engine includes an oscillator for generating a power carrier signal. A mechanism is included for providing command signals that select a mod... | 09/01/1992 |
| 5028890 | Voltage driven microwave amplitude modulation system A microwave amplitude modulation system maintains constant amplitude attenuation at very high modulation rates over a broad range of microwave frequencies in response to voltage driving signals derived from modulation signals. In the system, the video inp... | 07/02/1991 |
| 4954791 | Non-commensurate line length rf modulator In a reflective shunt-diode radio-frequency modulator the shunting diodes are spaces so that the transmission line sections between diode pairs have non-commensurate lengths. The transmission line length sections between diode pairs are selected so that a... | 09/04/1990 |
| 4870374 | Modulator producing phase modulation by combining amplitude modulated signals A system is described for using the modulation of the phase of a RF carrier as means of transmitting information. The RF input is split into four quadrature components each of which is passed through individual amplitude control attenuators and then summe... | 09/26/1989 |
| 4140982 | Transistor microstrip oscillator and diode attenuator modulator An RF oscillator and modulator especially useful for UHF applications. The oscillator may comprise a series-tuned Colpitts circuit with the tuned circuit including microstrip transmission lines as impedance elements. The modulator includes a pair of seria... | 02/20/1979 |
| 4047127 | RF oscillator and modulator having regulated low harmonic output An RF oscillator and modulator produces a stable moudlated RF signal with a varying voltage source and without the requirement for critical device selection. A bias voltage for the oscillator transistor is provided by diode means at the oscillator output,... | 09/06/1977 |
