Abstract: A wall-mountable perch includes: a frame including: first horizontal side members; a first cross member connected to each of the first horizontal side members proximate to a respective distal end of each of the first horizontal side members; second horizontal side members connected to the first horizontal side members; a platform connected to the second horizontal side members; a plurality of support arms each having a proximal end connected proximate to a proximal end of the frame, each support arm extending vertically upward from the frame; tension arms each connected to a respective horizontal side member; and adjusting means for producing tension in the tension arms and for causing a second cross member of the wall-mountable perch to move closer to the platform.

Abstract: The invention relates to the synthetic functionalization of an anthraquinone molecule that is substituted with at least one hydroxyl or amino group. In some aspects of the invention a mixture containing said anthraquinone starting material, an aldehyde, a base, an optional solvent, and an optional catalyst is reacted with hydrogen and then with an oxidant. In other aspects of the invention the synthetic functionalization of the anthraquinone molecule takes place electrochemically rather than chemically, through the use of a divided electrolytic cell.

Abstract: A mixed reality (MR) system that implements methods to allow two or more users to collaboratively access and interact with 3D models in MR environments. The collaboration includes a registration process allowing users to each register their MR system to their present space with 1-click registration. The presenter performs the registration and co-located users can utilize an image of what the presenter was viewing (a registration “photo”) to register to the space using the 1-click registration process. Remote collaborators register to a different space using the 1-click registration process. With the collaboration methods, a presenter controls whether or not the collaborators can roam freely from the presenter's current location or are only able to move a predefined amount so as share a view of the 3D model-based MR environment as the presenter. Collaborators are shown lines of sight of the other users and avatars of those that are physically remote.

Abstract: A mixed reality (MR) system that implements navigation methods for 3D models in MR environments. The navigation methods allow a user to navigate themselves about a 3D model (such as an MR environment including one or more buildings/structures) while in an MR environment. The navigation methods include an elevator feature or navigation mode that allows the user to move accurately between “floors” of the 3D model used to provide the MR environment (move to a next upper or lower floor from their present position). The navigation techniques include a jump feature or navigation mode. The jump feature allows the user to move to any point in an MR environment created using a 3D model that they can presently see in the display of the MR environment or a location that may be partially obscured from the user's view.

Abstract: A solid state nanopore device including two or more materials and a method for fabricating the same. The device includes a solid state insulating membrane having an exposed surface, a conductive material disposed on at least a portion of the exposed surface of the solid state membrane, and a nanopore penetrating an area of the conductive material and at least a portion of the solid state membrane. During fabrication a conductive material is applied on a portion of a solid state membrane surface, and a nanopore of a first diameter is formed. When the surface is exposed to an ion beam, material from the membrane and conductive material flows to reduce the diameter of the nanopore. A method for evaluating a polymer molecule using the solid state nanopore device is also described. The device is contacted with the polymer molecule and the molecule is passed through the nanopore, allowing each monomer of the polymer molecule to be monitored.
