Abstract: A method for flow correction includes, when an RFF flow modulator in a calibration flow condition, directing initial switching flow into the RFF flow modulator in a first direction to an exhaust with pressure regulation and reducing the initial switching flow to a minimum switching flow where a pressure satisfies a regulation condition. The calibration flow condition includes a primary column flow into the RFF flow modulator from a primary column and a secondary column flow from the RFF flow modulator to a secondary column. The operations include determining an adjusted switching flow for the calibration flow condition and determining a switching flow profile based on the adjusted switching flow. When the RFF flow modulator in an operating flow condition different from the calibration flow condition, the operations include directing an operating switching flow determined based on the switching flow profile in the first direction to the exhaust.

Abstract: A multi-dimensional gas chromatograph for analyzing compounds in a sample during a single run is disclosed. The multi-dimensional gas chromatograph includes a first column, a second column, and a modulator disposed between the first column and the second column. The modulator modulates at (i) a first modulation period over a first time period during the run and (ii) a second modulation period over a second time period during the run later than the first time, the second modulation period being different than the first modulation period.

Abstract: An analytical instrument assembly includes a gas chromatograph, a first detector, a second detector, and a pneumatic control module. The gas chromatograph includes a flow splitter configured to receive a sample. The first detector is coupled to the flow splitter. The second detector is coupled to the flow splitter. The pneumatic control module is coupled to the flow splitter and configured to deliver a carrier gas to the flow splitter. The flow splitter is configured to split the sample and deliver at least a first portion of the sample to the first detector and at least a second portion of the sample to the second detector at a first split ratio.

Abstract: A method and system to identify a suggested location for storing a data entry in a database including a plurality of divisions is provided. The method includes receiving entry criteria associated with the data entry, and searching the database using the entry criteria to locate similar stored data entries. At least one division for data entries is identified wherein the stored data entries are located. The at least one division is then presented to a user as the suggested location. The method and system may be applied in a network-based auction facility and the data entry may then be a user listing. The method may thus include identifying at least one potentially relevant category for the user listing as the suggested location.

Abstract: A gas turbine engine system comprises a rotor wheel, a plurality of blades, a lockwire and a locking key. The rotor wheel comprises a plurality of axial grooves extending through a periphery of the rotor wheel, and a plurality of posts formed between adjacent slots, each post having a circumferential slot. The blades are mounted in the axial grooves of the rotor wheel, each blade having a circumferential slot circumferentially aligned with the circumferential slots of the posts. The lockwire extends across the plurality of axial grooves of the rotor wheel within each of the circumferential slots of the posts and the blades from a first end to a second end to inhibit axial displacement of the blades within the grooves. The locking key is disposed between the first and second ends of the lockwire and provides support to at least one of the ends of the lockwire to prevent radially inward displacement.

Abstract: A head-mountable viewer with adjustable lenses is disclosed herein. The head-mountable viewer may include a frame with a first and second bore therein, each bore receives a first and second lens, respectively. The frame may further include a first and second side arms that each have a first and second tab, respectively. The first and second tabs are operatively connected to or attached to the first and second lenses, such that movement or adjustment of the first or second tabs corresponds to movement or adjustment of the first or second lenses, respectively. In this regard, the adjustability of the first and second lenses provides a single head-mountable viewer to be universally used, that is, any user may use the same head-mountable viewer by being able to adjust the lenses to best suit his or her comfort.

Abstract: Disclosed herein is a head-mountable viewer that includes a strap and tab that are positioned on the head-mountable viewer to provide a more reliable method of securing computing device within a cavity of the head-mountable viewer. In addition, the head-mountable viewer is manufactured to include various creases throughout, which thereby allows the head-mountable viewer to be manufactured in a way to reduce costs, such as by being able to manufacture the head-mountable viewer in a packaging form. The user is then able to easily follow simple instructions to change the head-mountable viewer from its packaging form to a usable form. In addition, the various creases of the head-mountable viewer provides a unique method to block sunlight and external noise from the eyes of the user via extension pieces.
