Publication number: 20190125268Abstract: A method for suppressing sensor noise in a spatially oversampled sensor array includes receiving spatially oversampled multi-channel sensor data from a region of interest and building a spatial model from the data for essential spatial degrees of freedom. The method further includes decomposing the data into the underlying spatial model to obtain associated amplitude components containing a mixture of original temporal waveforms of the data and, for each channel of the multi-channel sensor, estimating time-domain amplitude components using cross-validation. Next, for each channel, based on the estimated time-domain amplitude components, sensor noise and/or artifacts for that channel are identified. Finally, for each channel, the identified sensor noise and/or artifacts can be suppressed from the data.Type: ApplicationFiled: May 26, 2017Publication date: May 2, 2019Inventors: Samu Taulu, Eric D.

Publication number: 20190125313Abstract: Described herein are chargers for wirelessly charging an ultrasound imaging device. The charger may include a base member, a transmitter coil coupled to the base member, and a cradle extending from the top surface of the base member and including a surface configured to receive the ultrasound imaging device, where the first surface is disposed a vertical distance above the top surface of the base member. The cradle may be configured such that no portion of the ultrasound imaging device contacts the top surface of the base member when the cradle holds the ultrasound imaging device. The cradle may be configured to hold the ultrasound imaging device so as to substantially maintain alignment of a receiver coil of the ultrasound imaging device with the transmitter coil.Type: ApplicationFiled: October 26, 2018Publication date: May 2, 2019Applicant: Butterfly Network, Inc.Inventors: Dominick Mastri, Matthew de Jonge, Stephen Christopher, Paul Maxted, Matthew R.

Publication number: 20190125314Abstract: The liquid sample capture apparatus captures a sample of a liquid and holds the sample for optical analysis. The apparatus may include a mount which is traversed by a sample conduit. The mount may have an elongated shape and two ferrules may be placed within the mount along the longitudinal axis of the mount. An end of each of the ferrules may extend into the sample conduit forming a narrowing of the sample conduit which holds the liquid and prevents it from escaping prior to analysis. The opposite ends of the ferrules may each be connected to an optical cable. The optical cables may be connected to an analytical device, for example, a spectrometer. The apparatus may be mounted within a toilet bowl where it may capture and analyze a urine sample.Type: ApplicationFiled: December 27, 2018Publication date: May 2, 2019Inventors: David R. Hall, Joshua Larsen, Jared Reynolds

Publication number: 20190125315Abstract: An apparatus includes a transfer adapter, a puncture member, a disinfection member, and a fluid reservoir. The transfer adapter has a proximal end portion and a distal end portion, and defines an inner volume configured to receive the puncture member. The transfer adapter is coupled to the disinfection member. The distal end portion of the transfer adapter includes a port fluidically coupled to the puncture member and configured to be placed in fluid communication with a bodily-fluid of a patient. The proximal end portion is configured to receive a portion of the fluid reservoir to allow the fluid reservoir to be moved within the inner volume between a first position, in which a surface of the fluid reservoir is placed in contact with the disinfection member, and a second position, in which the puncture member punctures the surface to place the puncture member in fluid communication with the fluid reservoir.Type: ApplicationFiled: September 28, 2018Publication date: May 2, 2019Applicant: Magnolia Medical Technologies, Inc.Inventors: Gregory J. BULLINGTON, Richard G. PATTON, Shan E. GAW

Publication number: 20190125317Abstract: A biopsy device includes a hollow needle, and a sample-receiving device that is movable in the hollow needle. A power-driven element having a motor is provided. A transport device is drivably coupled to the motor. The transport device includes a toothed flexible member drivably engaged with a drive gear. The toothed flexible member has a distal portion coupled to the sample-receiving device. The toothed flexible member is configured to move the sample-receiving device in the hollow needle between an extended position and a retracted position. The toothed flexible member has a proximal portion that extends proximal to the proximal end of the hollow needle. A housing element has a helical coiling-up groove configured to accommodate the proximal portion of the toothed flexible member when the sample-receiving device is retracted to the retracted position.Type: ApplicationFiled: December 27, 2018Publication date: May 2, 2019Inventors: Karsten Videbaek, Martin B.
