  • Patent number: 11967343
    Abstract: A method of generating a modified video file using one or more processors is disclosed. The method comprises detecting at least one object represented in the original video file using a computer vision object detection technique. A frequency of motion of the at least one detected object is determined. A playback speed of the original video file or a playback speed of an audio track is adjusted, such that the frequency of motion of the at least one detected object corresponds to a characteristic frequency of the audio track. The audio track and the original video file are combined such that motion of the at least one detected object is synchronized with the audio track.

  • Publication number: 20240094156
    Abstract: Methods and devices useful for determining the analyte concentration of a sample using output currents obtained from an input potential in the kinetic potential region of a redox mediator are disclosed. Preferably, the input potential used to generate the output currents from the kinetic potential region of the redox mediator is continually increasing with time after initiating the analysis. A method of selecting an initial input potential within the kinetic potential region of a redox mediator based on the sensitivity of an individual or batch of subcutaneously insertable test sensors also is described. A method of selecting an analysis input potential within the kinetic potential region of redox mediator based on the sensitivity of an individual subcutaneously inserted test sensor also is described where the analysis input potential is increased with insertion time.

  • Patent number: 11918803
    Abstract: Disclosed herein are systems and methods for nerve conduction block. The systems and methods can utilize at least one renewable electrode. The methods can include delivering a first direct current with a first polarity to an electrode proximate nervous tissue sufficient to block conduction in the nervous tissue. Delivering the first direct current can place the nervous tissue in a hypersuppressed state at least partially preventing conduction of the nervous tissue after cessation of delivering of the first direct current. The nervous tissue can be maintained in the hypersuppressed state for a desired period, such as at least about 1 minute.

  • Patent number: 11446184
    Abstract: Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing.

  • Patent number: 11027050
    Abstract: Disclosed herein are devices and methods for reduced pressure tissue therapy. Some variations of suction devices for reduced pressure tissue therapy comprise a housing, a suction force generating mechanism located within the housing, and a storage module configured to retain tissue exudates. In some variations, the storage module includes a sleeve configured to collect tissue exudates. The sleeve may include a support element to help maintain the lateral structural integrity of the sleeve and/or retain the cross-sectional geometry of the sleeve under negative pressure. In use, the storage module may reduce sanitary and/or biohazard risks by preventing the exudates from contacting the housing and/or suction force generating mechanism. The storage module is configured to be replaced so that the housing and suction force generating mechanism can be used for more than one session.

  • Patent number: 10792404
    Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure, or space between it and the surface of a patient, by forming an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.

  • Publication number: 20200237565
    Abstract: Disclosed herein are devices, systems and methods for delivering reduced pressure to a load-bearing wound site. The device can include a distal port configured to connect to a wound dressing positioned over the wound site; a proximal port located a distance from the distal port and configured to connect to a reduced pressure source, and a conduit body having an inner channel extending between the distal port and the proximal port. When the distal port is applied to the wound dressing positioned over the wound site the proximal port is positioned at a non-load bearing location remote from the wound dressing. The inner channel has a non-circular profile having a width larger than a height of the conduit body.
