Abstract: Head-mounted display systems with power saving functionality are disclosed. The systems can include a frame configured to be supported on the head of the user. The systems can also include a head-mounted display disposed on the frame, one or more sensors, and processing electronics in communication with the display and the one or more sensors. In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame is in a certain position (e.g., upside-down or on top of the head of the user). In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame has been stationary for at least a threshold period of time.

Abstract: Methods, apparatuses, and kits for detection of substances in water by forming a complex with an indicator reagent and filtering the complex on a filter or membrane are described. The concentrated indicator on the filter, membrane or other capture device provides a colorimetric readout that can determine the amount of substance present in a water sample. A computer-implemented method for determining the concentration of substances in water based on color data from the colorimetric readout is also described.

Abstract: A cutting die for cutting a plurality of parts of an article of footwear from a bulk material. The cutting die includes a first cutting member that cuts a first part of the article of footwear from the bulk material. The cutting die also includes a second cutting member that cuts a second part of the article of footwear from the bulk material. The second cutting member is fixed to the first cutting member to cut the first and second parts together with a single stroke of the cutting die relative to the bulk material. The first and second parts are separate and distinct from each other and have different shapes.

Abstract: This invention discloses a method of forming a conductor on a copper conductor on a semiconductor interconnection surface. A paste of copper material is formed over at least a portion of the semiconductor interconnection surface. A laser beam is directed against the paste. The laser beam is moved along the paste in accordance with a pattern to define the conductor. The laser beam fires and sinters the paste to form the conductor. The remaining paste which remains unfired is removed. The surface and the fired paste is then maintained in an inert atmosphere while heated to a sufficient temperature to provide a high quality copper conductor on the surface.

Abstract: A cylindrical lock on a door panel has an outside actuating lever and an outside nut. Torque from both the nut and the outside lever is transferred to a substantially planar torque plate engaging the door panel and having a central opening bounded by arcuate edge surfaces spaced away from external threads on the lock hub. The central opening is also bounded by chordal edge surfaces disposed next to chordal surfaces on the lock hub. The nut has chordal surfaces next to the chordal surfaces of the torque plate and has arcuate surfaces close to the arcuate surfaces of the torque plate, all of such surfaces being in the plane of the torque plate.

Abstract: A mortise lock having reversible features to permit accommodating both left and right hand door applications. The lock includes the novel features of a resilient fire stop, simultaneous retraction of both the dead bolt and latch bolt mechanism by operation of the interior handle, and a three-position thumb turn function which variously unlocks the lock, locks against operation of the latch bolt by the exterior handle and finally, locks the latch bolt against operation by the outside handle and deploys a secure dead bolt. Other features of the lock include clockwise and counter clockwise rotation of either handle, separate rotation of the inside and outside handle and an auxiliary latch which prevents externally induced retraction of the latch bolt when the door is closed. Features also include an auxiliary lever handle assist spring. A new slide plate and cam operated lock works are provided to accomplish the locking function of the present invention.

Abstract: A formed sheet metal rectangular-shaped frame is positioned between two sheet metal side panels which may be embossed to provide the appearance of small wood panels. The frame includes an elongated frame member for each edge of the door, and each frame member has two outwardly facing parallel spaced channel portions integrally connected by a center web portion. Extruded plastic trim members cover the top and side frame members and include longitudinally extending hook-shaped leg portions which project into the channel portions and snap-fit onto inwardly formed edge portions of the side panels. A foam insulation material is expanded between the side panels and also serves to space the side panels laterally from the frame to form a thermal barrier. The side trim members are interrupted or notched to receive the door hinges and a latch bolt housing which seat on the web portions of the corresponding frame members.

Abstract: The base section of a burial casket supports an internal latch mechanism which is effective to engage keepers projecting downwardly from a pivotally supported cover section and to draw the cover section firmly against a resilient gasket member disposed between the base and cover sections. The gasket member is molded as a one-piece rectangular frame and includes parallel spaced peripherally extending sealing portions, the inner portion having an inverted U-shaped wall configuration and the outer portion having generally a V-shaped wall configuration. The latch mechanism includes a rotary actuator having an externally threaded coupling portion projecting to a circular opening within the front wall of the base section. A resilient sealing ring or grommet is mounted within the opening, and a cap-like closure member includes a tubular coupling portion which projects through the opening and threadably engages the coupling portion of the rotary actuator.
