  • Patent number: 12104994
    Abstract: At least some embodiments of the technology are directed to an automated slide processing apparatus configured to apply at least one reagent to a specimen carried by a microscope slide. The slide processing station can include a support element with a support surface, at least one vacuum port, and a sealing member having a non-round shape. In an uncompressed state, the scaling member can extend upwardly beyond the support surface. In a compressed state, the scaling member can be configured to maintain an airtight seal with a backside of the microscope slide as the microscope slide is pulled against the support surface by a vacuum drawn via the at least one vacuum port.

  • Publication number: 20240077261
    Abstract: A thermal storage system includes a container, a thermal exchange device, a first thermal storage material, and a second thermal storage material. The first thermal exchange device is disposed in the container. The first thermal storage material is disposed in the container and is spaced apart from the thermal exchange device. The second thermal storage material is also disposed in the container in contact with the thermal exchange device. The first and second thermal storage materials are immiscible. The second thermal storage material is less reactive with the construction material of the thermal exchange device as compared to the first thermal storage material. Optionally, a second thermal exchange device can be submerged in the second thermal storage material. The first thermal exchange device is configured to supply heat to the second thermal storage material and the second thermal exchange device facilitates extraction of heat from the second thermal storage material.

    Abstract: A method and a system for modeling a three-dimensional geological structure. A method may comprise selecting input data from well measurement systems, seismic surveys or other sources, inputting the input data into an information handling system, building a quotient space, projecting constraints to the quotient space, constructing depth functions on the quotient space, trimming against a fault network, and producing a three-dimensional model of horizons. A system may comprise a downhole tool. The downhole tool may comprise at least one receiver and at least one transmitter. The system may further comprise a conveyance and an information handling system. The information handling system may be configured to select an input data, build a quotient space, project constraints to the quotient space, construct depth functions on the quotient space, trim against a fault network, and produce a three-dimensional model of a geological structure.

  • Publication number: 20180182361
    Abstract: Musical instruments have been covered in ornamentation since the beginning of time. Often, the designs shown on an instrument are an integral part of the performance. However, playing the instrument creates wear. Some wear on the instrument may he desirable, to authenticate that the instrument was used during a performance. However, wear on the back of the instrument may interfere with the functionality of the instrument. For example, wear on the front of a guitar from picking shows authenticity, but scratches on the hack of the guitar may interfere with the resonance chamber. This problem of balancing wear and preservation is a difficult balance to strike. What is needed is a protective attachment that preserves the functionality of the instrument, but allows it to age and demonstrate authenticity.

  • Publication number: 20170287455
    Abstract: An apparatus for covering a musical instrument such as a guitar. The system comprises a back section and a front section with each of the back and front sections being affixed along a lateral edge to a side section. The cover is formed with an interior area into which the musical instrument is inserted. The musical instrument is protected from damage in the event the instrument is mishandled, dropped or knocked into another object. Cut-outs in the sections provide access to the components of the instrument for a musician to access such components while playing the instrument with the cover system in place.
