  • Publication number: 20200337711
    Abstract: A surgical saw blade cartridge includes a bar, a blade and a drive link. The bar includes a first plate and an opposed second plate defining a space therebetween, and an opening in at least one of the plates for releasable connection to a saw. The blade includes a base moveably disposed in the space between the plates and a head integral with the base located outside of the bar. The head has teeth at least as wide as a portion of the bar adjacent the head. The drive link extends through the bar and is moveable therein with a proximal end configured for attachment to a drive component of the saw and a distal end connected to either the base of the blade or a pivot link. The bar includes a structural member adjacent the head that extends forward of the head.

  • Patent number: 10796492
    Abstract: A system for providing a configurable virtual reality environment model includes a plurality of wall panels that are removeably interconnectable with each other without a need for tools. A plurality of floor sections are removeably interconnectable without a need for tools and include a connection interface for removeably connecting the wall panels to the plurality of floor sections. The plurality of wall panels are configured to place physical walls in a location that corresponds to a virtual wall located within a virtual reality world such that when a virtual reality display shows the user touching a wall in the virtual reality world, the user feels the physical wall placed in the configurable virtual reality environment. At least one network accessible component associated with a portion of the plurality of wall panels provides tactile feedback to a user responsive to the user coming within a predetermined distance of a wall panel.

  • Patent number: 10716578
    Abstract: A blade cartridge for use with a surgical saw includes a bar and a rack. The bar includes a first holding feature for removably holding the bar static to the saw. The rack includes a base moveably disposed in the bar and has cutting teeth defining extending beyond the bar. A drive link extends from the base, providing a second holding feature for releasably engaging a reciprocating drive integral with the saw. One of the base and the bar includes a guide slot. The other of the base and the bar includes a static member extending into the guide slot. The guide slot and the static member allow the rack to reciprocally move from proximal to distal to proximal along a longitudinal axis of the bar. The bar includes two plates and a spacer between the plates. The base is located between the plates.

  • Patent number: 10255729
    Abstract: A system for providing a virtual reality experience includes a display associated with a field of view of a user. A virtual reality system renders a virtual realty world responsive to a movement of the user and displays the rendered virtual reality world to a user through the display. A configurable virtual reality environment model may be configured to place physical walls in a location that corresponds to a virtual wall located within with virtual realty world such that when the display shows the user touching a wall in the virtual reality world, the user feels the physical wall placed in the configurable virtual reality environment.

  • Patent number: 10208489
    Abstract: A system and method of removably attaching a flooring surface material to a subfloor. The subfloor may include a modular raised flooring system comprising a plurality of raised floor panels, and comprising a magnetic body, surface or underlayment material. The flooring surface material includes a magnetic attachment surface that holds the flooring surface material in place on the subfloor by magnetic attraction, but that allows removal for disassembly and/or replacement.
