Abstract: A device for sealing an aperture in a tissue includes: a foot including a distal portion configured to be disposed distal to the tissue when the device is implanted in a position to seal the aperture; and a flexible wing positionable against a distal surface of the tissue adjacent the aperture such that the flexible wing is disposed between the distal portion of the foot and the distal surface adjacent the aperture.

Abstract: Systems and methods are disclosed for automated lateral transfer and elevation of sortation shuttles. An example system may include a track having a first portion arranged in a first direction, a shuttle configured to move along the track, and a shuttle carriage system configured to move in a second direction transverse to the first direction, where the shuttle is configured to move from the track to the shuttle carriage system. The shuttle carriage system may include a first frame configured to support the shuttle, a first electromagnet configured to propel the first frame, and a second electromagnet coupled to the first frame, the second electromagnet configured to propel the shuttle off the first frame.

Abstract: Systems and methods are disclosed for passive braking systems for container shuttles. An example system may include a track having a first portion and a ramp portion disposed at an angle, a first electromagnet disposed along the first portion, a shuttle with a permanent magnet that is configured to interact with the first electromagnet to propel the shuttle along the track, and a first metal block disposed along the ramp portion. The shuttle may enter the ramp portion at a first speed and exit the ramp portion at a second speed due to an eddy current induced in the first metal block by the permanent magnet.

Abstract: Embodiments include an apparatus and method for building courses. For example, one embodiment of a course builder apparatus comprises: a course builder application to retrieve data from a database, the data usable for constructing one or more online courses; a graphical user interface (GUI) of the course builder application for designing an online course, the GUI comprising: a template region in which one or more published classroom activity templates and/or step templates are graphically displayed; an editing region into which a designer of a course may select and drag one or more of the published classroom activity templates or step templates, the editing region comprising one or more fields or other graphical elements to allow the designer may edit the one or more published classroom activity templates or step templates.

Abstract: A virtual conferencing system is described which tracks events during a virtual conference, provides a user interface for reviewing the events, and allows a moderator and/or other participant to provide feedback related to the events.

Abstract: A virtual conferencing system is described which implements an interactive timeline.

Abstract: A virtual conferencing system is described for implementing a speaker queue.

Abstract: A scalable virtual conferencing system which implements a hub and spoke architecture. For example, one embodiment of a scalable virtual conferencing system comprises: a participant management module to logically group each participant in the virtual conferencing system into a hub or one of a plurality of spokes; and a data flow management module to control communication of information between participants in the spokes and participants in the hub, the data flow management module to limit intercommunication from the spokes to the hub in accordance with the manual user input and/or participant management policy; wherein at least one participant in a first spoke is designated as a spoke leader for the first spoke, the spoke leader logically grouped into both the hub and the first spoke, the data flow management module to allow information generated within the first spoke to be propagated into the hub based on input from the spoke leader.

Abstract: A method is disclosed for portraying physical visual attention cues or visual cues normally present in a conventional physical world in a virtual conference or class. The visual cues can be emulated by electronic signals in a video environment through physical interactions with the computer input by the user or participant of the virtual conference or image recognition algorithms provided by the video conferencing system.

Abstract: A data collection system for surfing which includes a data collection device mounted on the upper torso of the surfer or on the surf board. The device includes a clock, GPS unit, three dimensional accelerometers, three dimensional gyroscopes, and a microprocessor and data store for processing the signals from the GPS unit, three dimensional accelerometers and three dimensional gyroscopes. The microprocessor is programmed to identify and collect signal data to derive information identifying one or more parameters including number of waves passed up, power of each wave, size and frequency of the waves, time when a wave is caught, number of paddles required to catch a wave, time between catching the wave and the surfer standing up, distance travelled and speed during ride, time when rider exits the wave, acceleration during each manoeuvre during the ride, g force and speed during turns.
