Reception of Multiple Telemetry Signals via One Dish Antenna
Read More >>
Telemetry signals coming from slightly different directions can be separated.
A microwave aeronautical-telemetry receiver system includes an antenna comprising a seven-element planar array of receiving feed horns centered at the focal point of a paraboloidal dish reflector that is nominally aimed at a single aircraft or at multiple ...Read More >>
Space-Qualified Traveling-Wave Tube

TWT was developed for use as a high-power microwave amplifier for high-rate transmission of data.
The L-3 Communications Electron Technologies, Inc. Model 999HA traveling-wave tube (TWT), was developed for use as a high-power microwave amplifier for high-rate transmission of data and video signals from deep space to Earth (...Read More >>
Smart Power Supply for Battery-Powered Systems
Read More >>
This power supply can be used in remote vehicles, or for any application requiring battery power or battery charging.
A power supply for battery-powered systems has been designed with an embedded controller that is capable of monitoring and maintaining batteries, charging hardware, while maintaining output power. The power ...Read More >>
Parallel Processing of Broad-Band PPM Signals
Read More >>
Timing-error correction is independent of timing-error estimation.
A parallel-processing algorithm and a hardware architecture to implement the algorithm have been devised for timeslot synchronization in the reception of pulse-position-modulated (PPM) optical or radio signals. As in the cases of some prior algorithms and architectures for parallel, discrete-time, digital ...Read More >>
Inexpensive Implementation of Many Strain Gauges
Arrays of metal film resistors would sense strains at multiple locations.
It has been proposed to develop arrays of strain gauges as arrays of ordinary metal film resistors and associated electronic readout circuitry on printed-circuit boards or other suitable substrates. This proposal is a by-product of a ...
