  • Publication number: 20200220064
    Abstract: Test structures and methods for superconducting bump bond electrical characterization are used to verify the superconductivity of bump bonds that electrically connect two superconducting integrated circuit chips fabricated using a flip-chip process, and can also ascertain the self-inductance of bump bond(s) between chips. The structures and methods leverage a behavioral property of superconducting DC SQUIDs to modulate a critical current upon injection of magnetic flux in the SQUID loop, which behavior is not present when the SQUID is not superconducting, by including bump bond(s) within the loop, which loop is split among chips. The sensitivity of the bump bond superconductivity verification is therefore effectively perfect, independent of any multi-milliohm noise floor that may exist in measurement equipment.

  • Publication number: 20200141111
    Abstract: An apparatus, system, and method is provided to connect precast concrete panels to a structural member. The connector can have a receiving member embedded in a precast concrete panel and can further have an attachment member that selectively interconnects to the receiving member. This attachment member can have a surface that is oriented substantially perpendicular to the precast concrete panel and that receives or supports a structural member such as a floor joist or a second precast concrete panel. The configuration of a protrusion of the attachment member allows for a rapid and secure interconnection with an aperture in the receiving member. A builder can use the connector system described herein to rapidly and securely assemble multiple precast concrete panels to structural members in the construction of, for example, a parking garage or other similar structure.

  • Publication number: 20200032326
    Abstract: Described herein are ultrasensitive methods to detect the presence and/or measure the levels of short target nucleic acids, such as microRNAs, in a sample. Such a method can involve the use of a capture probe and a detection probe, each of which is complementary to a segment of the short target nucleic acid. The capture probe and a detection probe may be hybridized with the target nucleic acid in the sample and the complex thus formed can be detected, for example, by a single molecular array assay.

  • Publication number: 20190219647
    Abstract: A system and method for providing virtual real-time MRI-guidance for a biopsy outside of a conventional MRI scanner is described. MR images and ultrasound images of a region of a patient's body are simultaneously acquired during a pre-biopsy procedure. Respiratory states that the patient may experience during the biopsy are then determined from the acquired ultrasound images, and each respiratory state is associated with corresponding MR images. The MR images are indexed with their corresponding respiratory state. Ultrasound images are then acquired of the patient during a biopsy procedure. The respiratory state of the patient is determined from the ultrasound images, and the corresponding indexed MR images are displayed.

  • Patent number: 10074385
    Abstract: A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.
