Abstract: A method includes receiving, with a processor in communication with a first exercise machine, a first request for an exercise class, the first request being provided by a first user of the first exercise machine. The method also includes providing a video file associated with the exercise class to the first exercise machine, providing a notification to a second user indicating that the first user has chosen to participate in the exercise class, and receiving a second request for the exercise class provided by the second user. The method further includes providing the video file to a second exercise machine of the second user via the network. In such a method, display of the video file via a display of the second exercise machine is synchronized with display of the video file via a display of the first exercise machine.

Abstract: An apparatus for sensing cavitation in liquid flowing through a conduit in a housing includes an ultrasonic transducer system having one or more ultrasonic transducers attached to the housing and arranged in acoustic communication with the liquid, and control electronics connected to the ultrasonic transducer system. The control electronics is configured to drive the transducer system to send an ultrasonic signal through the flowing liquid, wherein the transducer system receives the ultrasonic signal and generates an electronic cavitation detection signal representing a strength of the received ultrasonic signal.

Abstract: A catheter includes a catheter body and a distal tip section that includes an elongated member that extends along a longitudinal axis. An anchor mechanism can be disposed along an outer surface of the elongated member and/or within the elongated member in a first configuration. In a second configuration, the anchor mechanism can be configured to extend radially outward with respect to the longitudinal axis to surround at least a portion of the distal tip section.

Abstract: Disclosed herein are surgical staple line reinforcement materials and methods of production and use thereof.

Abstract: A head utility system (20) comprising: a headset (22) comprising: a first power or data connector (28) for connecting to an off-headset power or data system (30); and a second power or data connector (38); the head utility system further comprising: headwear (24) for wearing over the headset, the headwear comprising: a headwear power or data connector (44) for connecting to the second power or data connector; wherein the second connector and the headwear connector are arranged to be releasably connected when the headwear is worn over the headset, such that power or data can be transferred between the headset and the headwear.

Abstract: An exercise machine includes a processor, a first display, a deck, and a belt rotatable about the deck. The machine also includes a sensor operably connected to the processor and configured to detect a first performance parameter of a first user running on the belt of the exercise machine. The processor is configured to receive information indicative of a second performance parameter of a second user, the second performance parameter being detected at an additional exercise machine during display of the at least part of the exercise class on a display associated with the additional exercise machine. The processor is also configured to cause the second performance parameter to be displayed on the first display together with the first performance parameter.

Abstract: A composition for reducing or preventing development of one or more symptoms of alcohol consumption includes at least prickly pear extract, reduced L-Glutathione, N-Acetyl-L-Cysteine (NAC), licorice root extract, and milk thistle, which are present in the composition in effective amounts sufficient in combination to reduce or prevent development of one or more detrimental symptoms of alcohol consumption. Also disclosed are methods of reducing or prevent the development of detrimental symptoms of alcohol consumption using the compositions.

Abstract: A method includes receiving a video input, receiving an indication of a first segment type corresponding to a first workout activity being performed in the video input, and generating a segmented timeline with the processor, the segmented timeline including a plurality of segments, and at least one segment of the plurality of segments corresponding to the first workout activity. The method further includes generating a user interface with the processor, the user interface including the segmented timeline displayed together with at least part of the video input. The method also includes providing the user interface to a plurality of exercise machines via a network.
