Abstract: In order to reduce the amount of electrical insulation needed for voltage isolation of large voltages generated by a voltage multiplier, the voltage multiplier can be shaped to smooth out electric field gradients. The voltage multiplier can comprise multiple sections, each section located in a different plane. The voltage multiplier can comprise a negative voltage multiplier and a positive voltage multiplier, each inclined at different angles with respect to each other. The voltage multiplier can include a curved shape.

Abstract: A computer system presents a virtual object on a display of the computer system which represents an action at a location in space. If a user of the computer system approaches the location, the computer system presents one or more stimuli to encourage movement away from that location. The appearance of the object may vary as the user of the computer system moves. The appearance of the object may include information and may vary with a change of state. Multiple such virtual objects may be used to indicate a path.

Abstract: A computer system provides directional guidance to a user wearing a head-mounted display (HMD). This is accomplished by obtaining a path through real-world space and presenting multiple virtual path indicators to the user on the head-mounted display. The virtual path indicators are overlaid on a view of a portion of the real-world space and direct the user to follow the path through real-world space.

Abstract: A computer system detects an object in a field-of-view (FOV) using at least one sensor coupled to the computer system and determines a shape of the object using a processor of the computer system. An overlay element having the shape and a changeable characteristic is created and a value of a parameter is obtained. A representation of the overlay element is rendered with the changeable characteristic set based on a value of the parameter and presented on a display of the computer system to at least partially occlude the object.

Abstract: A computer system detects an object in a field-of-view (FOV) using at least one sensor coupled to the computer system and determines a shape of the object using a processor of the computer system. An overlay element having the shape and a changeable characteristic is created and a series of values of a parameter over a period of time is obtained. Multiple representations of the overlay element are rendered with the changeable characteristic changed based on the series of values of the parameter and serially presented on a display of the computer system to at least partially occlude the object.

Abstract: An apparatus is provided which comprises pressure pass-thru means, which includes: an optic fiber having a first end and a second end; a first connector coupled to the first end; a second connector coupled to the second end; a housing between the first and second ends, wherein the housing covers a portion of the optic fiber, wherein a portion of the optic fiber in the housing is bare; a filing material inside the housing; and a swaged gland fitting on the housing to secure the apparatus to a pressure boundary.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

Abstract: A method for additively manufacturing a three-dimensional article includes depositing feed materials through a material feeder to a growth surface. The feed materials include at least one of a first feed material, a second feed material and a third feed material. At least one of the first feed material, the second feed material and the third feed material is different. The method also includes exposing the feed materials to electromagnetic energy to form a melt pool. The melt pool includes at least one of a molten first feed material, a molten second feed material and a molten third feed material. The method further includes solidifying the melt pool.

Abstract: Apparatuses and methods for targeted row refreshes are disclosed herein. In an example apparatus, a predecoder receives a target row address and determines whether a target row of memory associated with the target row address is a primary or a redundant row of memory. The predecoder is further configured to cause one or more rows of memory physically adjacent the primary row of memory to be refreshed if the primary row is the target row or one or more rows of memory physically adjacent the redundant row of memory to be refreshed if the redundant row of memory is the target row of memory.
