  • Publication number: 20180262699
    Abstract: An apparatus and method for generating images of specimens is disclosed. The apparatus includes an imaging system, controller, and user interface. The imaging system generates a plurality of component images of a specimen, each component image corresponding to a different viewing condition. Each image is represented by an intensity as a function of location on the specimen. The controller stores the component images and generates a compound image from a plurality of the component images. The compound image includes a weighted sum of first and second ones of the component images, the controller displaying the compound image on a display controlled by the controller. The user interface is adapted to control a weighting factor used in generating the weighted sum in response to user input. The controller redisplays the compound image after the weighting factor is changed in response to user input.

  • Patent number: 10072261
    Abstract: Aspects of the present disclosure include methods for double coupling a nucleoside phosphoramidite during synthesis of an oligonucleotide. The method can include coupling a free hydroxyl group of a nucleoside residue with a first sample of a protected nucleoside phosphoramidite via an internucleoside P(III) linkage, followed by exposure to an oxidizing agent prior to a second coupling step with a second sample of the protected nucleoside phosphoramidite, and further exposure to an oxidizing agent. The method finds use in synthesizing an oligonucleotide on a solid phase support, such as a planar surface. The double coupling method can be utilized at one or more nucleotide positions during oligonucleotide synthesis thereby reducing single base deletion rates. Oligonucleotide containing compositions synthesized according to the disclosed methods are also provided.

  • Patent number: 10010884
    Abstract: A droplet-based microfluidic device having a first confining plate, a second confining plate, and an actuator. Each confining plate includes a respective substrate and hydrophobic layer having a planar major surface. The first confining plate additionally includes a common electrode between its hydrophobic layer and substrate. The second confining plate includes an electrode array between its hydrophobic layer and substrate. The confining plates are disposed opposite one another with their major surfaces separated from one another by a gap. The actuator is to impart oscillatory sliding motion between the confining plates in a direction principally parallel to the major surfaces. The oscillatory sliding motion effectively allows voltages applied between the common electrode and the electrodes of the electrode array to move a microfluidic droplet located in the gap across the major surfaces without sticking.

  • Patent number: 9995421
    Abstract: In a vibration damper of a turbomolecular vacuum pump, a vacuum tightness function and a vibration damping function are both performed by one ore more toroidal rings made of an elastic material. The elastic rings assume a resting configuration while the vacuum pump is not operating and the damper is at atmospheric pressure, and they assume a compressed configuration while the vacuum pump is operating and the damper is under vacuum conditions. In the compressed configuration, the elastic rings are deformed due to a compression force. This deformation of the elastic rings prevents metal-to-metal contact between the vacuum pump and a vacuum chamber to which the pump is connected through the damper.

  • Patent number: 9972480
    Abstract: An ion guide generates a radio frequency (RF) field to radially confine ions to an ion beam along a guide axis as the ions are transmitted through the ion guide. The effective potential of the RF field includes an alternating series of barriers and wells. Ions may be trapped in individual wells in mass-dependent order, with larger masses trapped closer to a guide exit than smaller masses. The RF field may be scanned so as to release the ions from the ion guide in mass-dependent order, with larger masses released before smaller masses. The operating conditions may be set such that ions over the entire mass range arrive at a desired downstream focal point simultaneously, for example at an accelerator of a time-of-flight analyzer.
