Abstract: A method of depolymerizing a polymer by combining together the polymer with an enzyme (a hydrolytic enzyme capable of catalyzing cleavage of said (CO)—O bond of an ester or carbonate linkage of the polymer) and an aqueous liquid to provide a reaction mixture. The polymer comprises a (CO)—O bond of an ester or carbonate linkage. The reaction mixture defines a ratio eta (?) of liquid volume, in ?L, to total solids, in mg, that is less than 2 ?L/mg. Then, allowing an enzyme-catalyzed reaction of the enzyme with the polymer to take place thereby forming a reaction product.

Abstract: In some implementations, an insect trap includes a plurality of individual cells, with each of the cells being configured to trap very few, and in some instances a single flying insect. Each cell defines a cavity and may be provided with an independently operable door to selectively close the cavity. One or more sensors may sense the presence of an insect to be trapped.

Abstract: A disposable modular patella protector and clamp is disclosed, providing the ability for a surgeon to shift the procedure sequence of the implantation of the patella from the end of a total knee replacement procedure to anytime during the procedure by providing a modular clamp that holds and protects the patella prosthesis and prepared patella. The clamp may be positioned in a manner in which it does not obstruct the patella or the prosthesis, allowing the surgeon to attend to other elements of the procedure while the bone cement is allowed to cure.

Abstract: The physical 3D renderer described herein renders one or more captured depth images as a physical 3D rendering. The physical 3D renderer can render physical 3D surfaces and structures in real time. In one embodiment the 3D renderer creates a physical three dimensional (3D) topological surface from captured images. To this end, a depth image of a surface or structure to be replicated is received (for example from a depth camera or depth sensor). Depth information is determined at a dense distribution of points corresponding to points in the depth image. In one embodiment the depth information corresponding to the depth image is fed to actuators on sliding shafts in an array. Each sliding shaft is adjusted to the depth in the depth image to create a physical 3D topological surface like the surface or structure to be replicated.

Abstract: A patella protector may be positioned in a manner in which it does not obstruct a patella or a prosthesis, while providing protection for the patella from accidental damage during a surgical procedure, such as a knee replacement. The patella protector may be a clamp with two contact surfaces connected by a stainless steel connecting element providing an inward bias to hold the contact surfaces against the patella.

Abstract: A “Mixed-Reality Headset” include an attachment mechanism for a smartphone or other portable computing device. A combination of the smartphone display with various internal headset optics present both augmented reality (AR) and virtual reality (VR). The Mixed-Reality Headset provides low cost, high performance, easy to use AR and VR experiences with unmodified smartphone hardware, thereby improving user experience and interaction with smartphones. In various implementations, applications associated with the Mixed-Reality Headset consider user movement and tracking (e.g., head, eye, hands, body) and real-world environmental mapping when rendering AR and VR content. The Mixed-Reality Headset easily and quickly transitions between AR and VR scenarios by causing transparent optical members to either pass light or block light, thereby either showing or hiding views of the real world.

Abstract: Embodiments relating to a multi-mode display device are disclosed. For example in one disclosed embodiment a multimode display device includes a principal and a secondary image display mounted in a common housing configure to alternately emit light through a common transparent region in the viewing surface. The multimode display device is configured to display a first image on the principal image display at a first resolution or display a second image on the secondary image display of higher resolution than the first image and on a virtual plane behind the viewing surface of the display device. The multi-mode display device is configured to compare the a detected eye relief distance to a predetermined threshold and display the image on the appropriate image display and set the other image display to a non-display state.

Abstract: Embodiments relating to a wearable multi-mode display system actuatable by a wrist or hand are disclosed. For example, in one disclosed embodiment a first compact image is displayed in a first display mode via a display device, with the first compact image having a display resolution corresponding to a first application. While in the first display mode, a principal user input is received from the user's wrist or hand. In response, a second, different compact image is displayed. When the device is less than a predetermined distance from the user, an application image is displayed in a second display mode, with the application image having a greater display resolution. While in the second display mode, a secondary user input is received from the user's wrist or hand. In response, a graphical user interface element is controlled within the application image.
