  • Patent number: 12203129
    Abstract: The present disclosure provides methods and compositions for the multiplexed detection of multiple analytes from a sample. Analytes may be nucleic acid analytes. Detection of analytes may comprise contacting one or more sample subsets with hybridization probes, thereby generating one or more cumulative signal measurements capable of detecting the presence of absence of a plurality of analytes.

  • Patent number: 12168797
    Abstract: This disclosure provides methods, systems, compositions, and kits for the multiplexed detection of a plurality of analytes in a sample. In some examples, this disclosure provides methods, systems, compositions, and kits wherein multiple analytes may be detected in a single sample volume by acquiring a cumulative measurement or measurements of at least one quantifiable component of a signal. In some cases, additional components of a signal, or additional signals (or components thereof) are also quantified. Each signal or component of a signal may be used to construct a coding scheme which can then be used to determine the presence or absence of any analyte.

    Abstract: An ultrasound measurement device includes: a processing device and multiple ultrasound sensors that capture tomographic information of a physiological structure. The ultrasound sensors include a first ultrasound sensor including a first transducer having a first frequency response with a first resonant frequency, and a second ultrasound sensor including a second transducer having a second frequency response with a second resonant frequency different from the first resonant frequency. The first frequency response partially overlaps with the second frequency response.

    Abstract: A measurement device includes: a processing device and multiple sensors that capture tomographic information of a physiological structure. The sensors include a first sensor including a first transducer having a first frequency response with a first resonant frequency, and a second sensor including a second transducer having a second frequency response with a second resonant frequency different from the first resonant frequency. The first frequency response partially overlaps with the second frequency response. The second transducer transmits a signal that is reflected by the physiological structure to create a reflected signal, the first transducer generates a first received signal from the reflected signal, the second transducer generates a second received signal from the reflected signal, and the processing device normalizes the first received signal with the second received signal or the second received signal with the first received signal.

  • Patent number: 11998383
    Abstract: An enhanced stethoscope device and method for operating the enhanced stethoscope are provided. The enhanced stethoscope device generally operates by providing stethoscope sensors, ultrasonic sensors, and other sensors to obtain a series of measurements about a subject. The series of measurements may be correlated, such as by machine learning, to extract clinically relevant information. Also described are systems and methods for ultrasonic beamsteering by interference of an audio signal with an ultrasonic signal.

  • Patent number: 11950887
    Abstract: Some implementations of the disclosure describe a blood pressure measurement apparatus and method that enable continuous, non-invasive blood pressure measurement using sound and ultrasound transducers. In one implementation, a blood pressure measurement device includes: a first transducer configured to emit multiple soundwaves having multiple frequencies, the soundwaves configured to cause a blood vessel of a subject to vibrate; a second transducer configured to capture one or more ultrasound images of the blood vessel; and a processing device configured to: determine, based on the one or more ultrasound images, a wall thickness, a radius, and a resonant frequency of the blood vessel; and calculate, based on the wall thickness, the radius, and the resonant frequency, a blood pressure of the subject.

  • Patent number: 11879162
    Abstract: A non-transitory computer-readable storage medium storing executable instructions to cause a system to detect a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a measured change in signal generated by the fluorophore and quencher, when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher, when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.
