20100081373 | SATELLITE FEED ASSEMBLY WITH INTEGRATED FILTERS AND TEST COUPLERS - A dual-band feed assembly is configured to be coupled to a satellite repeater payload. The dual-band feed assembly includes a transmit filter assembly comprising a transmit pass-band filter configured to reject frequencies outside of a transmit frequency band and a low-pass and harmonic filter configured to reject receive band frequencies and harmonics of the transmit frequency band. The dual-band feed assembly further includes a receive filter assembly comprising a receive pass-band filter configured to reject frequencies outside of a receive frequency band and a high-pass filter configured to reject transmit band frequencies. A multi-port junction couples the transmit and receive waveguide assemblies to a dual-band horn. The dual-band feed assembly also may include receive and transmit test couplers. | 04-01-2010 |

20090140906 | GENERIC PICK-UP HORN FOR HIGH POWER THERMAL VACUUM TESTING OF SATELLITE PAYLOADS AT MULTIPLE FREQUENCY BANDS AND AT MULTIPLE POLARIZATIONS - Methods, systems, and apparatus are disclosed for high power thermal vacuum testing of satellite payloads using pick-up horns. Such pick-up horns can include at least one outer metal wall forming a metal body and at least one interior surface disposed in the metal body, forming at least one chamber in the metal body. The pick-up horn further includes a front metal surface disposed at a front end of the metal body, having at least one opening corresponding to the at least one chamber, and at least one high-power absorbing load disposed within the at least one chamber and in contact with the at least one interior surface. A pick-up horn may further include a serpentine coolant path disposed within the metal body between an outer surface of the at least one outer metal wall and the at least one high-power absorbing load. Related systems and methods are described. | 06-04-2009 |

20160091510 | CARTRIDGE DEVICE WITH FLUIDIC JUNCTIONS FOR COAGULATION ASSAYS IN FLUID SAMPLES - The present invention relates to analytical testing devices comprising fluidic junctions and methods for assaying coagulation in a fluid sample received within the fluidic junctions. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber, a first conduit comprising a first junction configured to split a biological sample into at least first and second segments, a second conduit comprising a first reagent, a first sensor region, and a first fluidic lock valve, and a third conduit comprising a second reagent, a second sensor region, and a second fluidic lock valve. The sample analysis cartridge further includes a pump configured to push the first segment over the first sensor region to the first fluidic lock valve, and push the second segment over the second sensor region to the second fluidic lock valve. | 03-31-2016 |
20160091511 | SINGLE CHANNEL CARTRIDGE DEVICE FOR COAGULATION ASSAYS IN FLUID SAMPLES - The present invention relates to analytical testing devices comprising a single channel with micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, to performing coagulation assays using a single channel with micro-environment sensors in a point of care test cartridge. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber configured to receive a biological sample and a conduit fluidically connected to the inlet chamber. The conduit includes a sensor chip including a first micro-environment sensor and a second microenvironment sensor, and a fluid lock valve. The sample analysis cartridge further includes a pump configured to push the biological sample over the first micro-environment sensor and the second microenvironment sensor to the fluidic lock valve such that the biological sample is positioned over the first micro-environment sensor and the second micro-environment sensor. | 03-31-2016 |
