US Classification:

324 7623

Abstract:

A time-domain baseband measurement method measures modulated microwave signals typically used in communication systems by converting microwave signals to baseband before measurement for improved accuracy compared to direct measurement at the microwave frequency. A downconverting receiver is first characterized using a prior characterization method and then the modulated microwave signal is applied to the downconverting receiver and the response of the downconverting receiver is removed to provide an accurate characterization of the modulated microwave signal. Such an accurate measurement of the modulated microwave signal can be used for communications system performance verification as well as for characterizing communications devices and systems. One particular application is the measurement of input/output characteristics of nonlinear power amplifiers using such modulated microwave signals.

Appl. No.:

16/263780

Inventors:

- Crane IN, US
Christopher H. Clark - Norco CA, US
Gary G. Yeakley - Norco CA, US

International Classification:

G01N 21/11
B67D 7/02
B67D 7/36

Abstract:

The present invention relates to an automated liquid transmission cell system capable of transferring solvents and samples to clean and fill the transmission cells. Three valves allow a plurality of system configurations to perform a variety of flushing and filling processes by changing the position of each valve. A plurality of tubes are connected to two of the valves such that changing the valve positions will redirect fluid transmission paths.

B01L 3/00

Abstract:

The present invention relates to a chemical vapor-sensor bag with an integrated sensor array to verify the presence of specific chemical vapors inside a sealed bag. In an exemplary embodiment, a device can be sealed within a vapor-sensor bag to allow the device to be transported to and tested for contaminants at the point of use by an end user of the device. In another exemplary embodiment, a device can be coupled to a gas port on a vapor-sensor bag to allow gas within the device to be tested for contaminants. In another exemplary embodiment, gas from a device can be streamed through vapor-sensor bag by coupling the device to a first gas port on a vapor-sensor bag and allowing gas to exit the bag through a second gas port.
