Patent number: 10987674Abstract: An apparatus includes a substrate, a first heating element, and a second heating element. The substrate includes a first portion, a second portion, and a third portion that is between the first portion and the second portion. The first portion is characterized by a first thermal conductivity, the second portion is characterized by a second thermal conductivity, and the third portion is characterized by a third thermal conductivity. The third thermal conductivity is less than the first thermal conductivity and the second thermal conductivity. The first heating element is coupled to the first portion of the substrate, and is configured to produce a first thermal output. The second heating element is coupled to the second portion of the substrate, and configured to produce a second thermal output. The second thermal output is different from the first thermal output.Type: GrantFiled: April 21, 2017Date of Patent: April 27, 2021Assignee: Visby Medical, Inc.Inventors: Boris Andreyev, Brian Ciopyk, Victor Briones, Jonathan Hong, David Swenson, Gregory Loney, Adam De La Zerda, Steven Chu

Publication number: 20210039097Abstract: A hand-held molecular diagnostic test device includes a housing, an amplification (or PCR) module, and a detection module. The amplification module is configured to receive an input sample, and defines a reaction volume. The amplification module includes a heater such that the amplification module can perform a polymerase chain reaction (PCR) on the input sample. The detection module is configured to receive an output from the amplification module and a reagent formulated to produce a signal that indicates a presence of a target amplicon within the input sample. The amplification module and the detection module are integrated within the housing.Type: ApplicationFiled: October 14, 2020Publication date: February 11, 2021Applicant: Visby Medical, Inc.Inventors: Boris ANDREYEV, Keith E.

Patent number: 10905401Abstract: Ultrasound imaging systems and methods with frequency (spectral) compounding for speckle reduction are disclosed. In one aspect, an ultrasound imaging system includes a transducer probe with interleaved transmit and receive arrays. The system may utilize ultrasound pulses having an optimized time-bandwidth product. In one aspect, a transducer probe with separate transmit and receive elements can enable transmission and reception of multiple ultrasound pulses, each centered at a different frequency, during the time of one A-scan. Thus, such a system can capture multiple independent speckle images without reducing overall B-mode framerate. In another aspect, the system may transmit a broadband pulse and may obtain separate speckle images by filtering the received echo using multiple spectral filters. The system may compound multiple images captured at different frequencies to provide speckle reduction.Type: GrantFiled: July 6, 2018Date of Patent: February 2, 2021Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yilei Li, Steven Chu
