  • Publication number: 20180130650
    Abstract: Methods, systems and devices that generate differential axial transport in a fluidic device having at least one fluidic sample separation flow channel and at least one ESI emitter in communication with the at least one sample separation flow channel. In response to the generated differential axial transport, the at least one target analyte contained in a sample reservoir in communication with the sample separation channel is selectively transported to the at least one ESI emitter while inhibiting transport of contaminant materials contained in the sample reservoir toward the at least one ESI emitter thereby preferentially directing analyte molecules out of the at least one ESI emitter. The methods, systems and devices are particularly suitable for use with a mass spectrometer.

  • Patent number: 9910103
    Abstract: A power supply unit (PSU) performs a PSU fault diagnosis using a PSU fault detection module. The PSU fault detection module detects a diagnostic trigger event and initiates a series of checks of selected sub-systems. The PSU fault detection module determines whether the trigger event occurred while the PSU was connected within an information handling system (IHS) or physically removed from the IHS. If the trigger event occurred while the PSU was connected within an information handling system (IHS), the PSU fault detection module electrically isolates the PSU from the IHS using an ORing device, which blocks current flowing into the PSU. The PSU fault detection module determines whether a short circuit exists within the electrically isolated PSU. If a short circuit is identified, the PSU fault detection module determines that the PSU is not functioning properly and provides a notification of a malfunction of the PSU.

  • Patent number: 9887856
    Abstract: A method may include, receiving, by a controller integral to a chassis, a user request to apply a switch configuration. The method may also include communicating from the controller to a remote access controller (RAC) integral to at least one module disposed in a plurality of slots of the chassis an indication that a user has requested application of a switch configuration. The method may further include receiving at the controller, in response to the indication, a request to download a switch configuration file from the controller to the RAC. The method may additionally include transferring from the controller, in response to the request to download the switch configuration file, the switch configuration file to the RAC such that the RAC applies parameters set forth in the switch configuration file in order to configure an in-band switch associated with the module comprising the RAC.

  • Publication number: 20170322180
    Abstract: Methods that allow independently applied pressures to a BGE reservoir and a sample reservoir for pressure-driven injection that can inject a discrete sample plug into a separation channel that does not require voltage applied to the sample reservoir and can allow for in-channel focusing methods to be used. The methods are particularly suitable for use with a mass spectrometer.

  • Publication number: 20170301527
    Abstract: Methods, systems and devices that provide fluid devices with at least one SPE bed adjacent (upstream of) a separation channel which may be in communication with an inlet of a Mass Spectrometer. The fluid device can be configured to operate using independently applied pressures to a BGE reservoir and a sample reservoir for pressure-driven injection that can inject a discrete sample plug into a separation channel that does not require voltage applied to the sample reservoir and can allow for in-channel focusing methods to be used. The methods, systems and devices are particularly suitable for use with a mass spectrometer but optical or other electronic detectors may also be used with the fluidic devices.

  • Publication number: 20170263432
    Abstract: A miniature electrode apparatus is disclosed for trapping charged particles, the apparatus including, along a longitudinal direction: a first end cap electrode; a central electrode having an aperture; and a second end cap electrode. The aperture is elongated in the lateral plane and extends through the central electrode along the longitudinal direction and the central electrode surrounds the aperture in a lateral plane perpendicular to the longitudinal direction to define a transverse cavity for trapping charged particles.

  • Publication number: 20170175181
    Abstract: Devices and methods generate an ordered restriction map of genomic DNA extracted from whole cells. The devices have a fluidic microchannel that merges into a reaction nanochannel that merges into a detection nanochannel at an interface where the nanochannel diameter decreases in size by between 50% to 99%. Intact molecules of DNA are transported to the reaction nanochannel and then fragmented in the reaction nanochannel using restriction endonuclease enzymes. The reaction nanochannel is sized and configured so that the fragments stay in an original order until they are injected into the detection nanochannel. Signal at one or more locations along the detection nanochannel is detected to map fragments in the order they occur along a long DNA molecule.

  • Publication number: 20170154063
    Abstract: Techniques for providing feed-based case management on an online social network. A user interface that includes a publisher and an information feed is provided. Information associated with a record is received and the record is updated in a database system. A feed item associated with the database system update is generated and provided in the information feed. The feed item includes one or more actionable selections providing a reference to the publisher. Selection of one of the one or more actionable selections causes the publisher to be operable to receive further information associated with the record. The record is capable of being updated based on the further information. In some implementations, the record is a case and the user interface serves as a single interface for all interactions required in solving the case.
