  • Patent number: 10401336
    Abstract: A sample analysis method includes directing a sample that contains one or more SVOC components to a GC column to temporally separate components present in the sample. Output gas from the GC column is expanded into a sample cell. The sample cell is held at a temperature and pressure that are lower than the temperature and pressure at an outlet of the GC column. The volume of the sample cell is sufficiently large for maintaining the one or more SVOC components in a gaseous phase. Infrared spectra of the components in the sample cell are obtained using a Fourier transform infrared spectrometry system.

  • Patent number: 10386342
    Abstract: A sample injection method for liquid chromatography is performed with an injection valve having a waste port, two sample loop ports, and two high-pressure ports. One high-pressure port can be connected to a pump and the other high-pressure port can be connected to a chromatography column. A sample loop is connected to one of the sample loop ports on one end and to a pump volume of a sample conveying device on the other end. A section of the sample loop can be separated to facilitate receiving a sample fluid in the sample loop. A control unit controls the injection valve and the sample conveying device. The sample injector allows a sample to be loaded into the sample loop and then pressurized to an operating pressure prior to injecting the sample into the chromatography column. The sample loop may also be isolated from the operating pressure for facilitating depressurization of the loop.

  • Patent number: 10378935
    Abstract: A facade gantry allows for close inspection of a facade using remotely operated cameras, probes, and/or sampling devices. These devices are located in a housing that is positioned in front of a facade by a system of cables, from which it is suspended, that allow for movement in any direction in a plane. Two cables are attached to the housing containing the sensors and tools and are wound onto two separate spools located on the roof at the vertical boundaries of the inspection area. By winding and unwinding these spools, the housing can be raised, lowered, and moved from side to side. The invention further has an optional “shed” located on the ground that protects pedestrians in the case of a suspension system failure. The shed moves to maintain a position directly under the housing. The gantry optionally allows for repair of the facade by using remotely operated repair tools.

  • Patent number: 10377189
    Abstract: A preliminary positioning method for a TPMS uses a receiver to receive a tire pressure signal, then obtains the ID code contained in the obtained tire pressure signal, then compares the ID code with the corresponding ID codes stored in the database, and defines the ID code as a known ID code, when the ID code is found to match with one of the corresponding ID codes prestored in the database. Repeating the above steps until the ID codes of all received tire pressure signals all have been compared. If the number of the known ID codes is equal to the number of the sensors, the known ID codes are designated as specific tires according to an indication of the respective tire pressure signals, so that the positioning function can be achieved in a short period of time.

  • Patent number: 10352806
    Abstract: A pressure sensor device which uses appropriate passivation materials/patterns to make the device more robust and resistant to a hot and humid environment. The pressure sensor device uses moisture resistant passivation material(s) covering exposed glass areas, including sidewalls, and bonding interfaces to avoid the glass and bonding interfaces absorbing and reacting with moisture, thus maintaining the integrity of the device output after exposure in a humid/hot environment. These passivation materials/patterns used for the MEMS devices described may be applied to any MEMS based sensors and actuators using glass as one type of material for fabrication. The pressure sensor devices may be front side absolute pressure sensors, differential pressure sensors, or back side absolute pressure sensors.
