Abstract: A voltage-multiplier can be more compact by arrangement in a stack of separate voltage-multiplier-stages. Each of the voltage-multiplier-stages can include electronic-components on a planar-face of a circuit-board. The planar-face of each circuit-board can be parallel with respect to other circuit-boards in the stack. The electronic-components on each voltage-multiplier-stage can be configured to multiply an input-voltage to provide an output-voltage with a higher voltage than the input-voltage. Each voltage-multiplier-stage in the stack can be electrically coupled to two adjacent voltage-multiplier-stages, except that two outermost voltage-multiplier-stages of the stack can be electrically coupled to only one adjacent voltage-multiplier-stage of the stack.

Abstract: A power tool includes a primary housing, and a motor situated within the primary housing. The power tool also includes a circuit board located within the primary housing, and a light source mounted to the circuit board. The power tool also includes an optical fiber including a first end and a second end. The first end may be coupled to the light source and may be configured to receive light generated by the light source. The second end may be configured to emit the light to an outside of the primary housing to provide a status indication to a user and/or to illuminate a work area.

Abstract: A computer system enhances guidance information on a display, allowing a user position and orientation in 3D space to be achieved. In some embodiments, the guidance is visual, for example the blurring of display objects not at the desired position. In some embodiments, the guidance is aural, for example placing a sound moving to the desired position. In some embodiments, the guidance is tactile, for example using haptic pads attached to a head-mounted display to push the user in a specified direction. The system may be used to guide the user spatially for the performing of a task, to help the user avoid sensitive components, or to guide the user to position a sensor, such as a camera, in an optimal direction for taking measurements. The system includes head positioning, hand positioning and gaze positioning techniques.

Abstract: A method of forming a configurable substrate includes depositing a volume of trans-cyclooctene on a configurable substrate of a fluidic device, and forming a bioorthogonal tethered protein on the configurable substrate. The bioorthogonal tethered protein may be formed by attaching a tetrazine-modified protein or tetrazine-modified functional protein fragment to the trans-cyclooctene, wherein the tetrazine-modified protein or tetrazine-modified functional protein fragment is configured to bind to a target analyte.

Abstract: A blank forms a dispenser carton. The dispenser carton receives a rolled sheet to form a dispenser carton assembly. The dispenser carton has a top panel. A dispensing state of the dispenser carton the top panel includes a pair of locking tabs with notches received by a pair of flaps of side panels of the dispenser carton. The pair of flaps each have flap notches. The flap notches provide a gap between a top panel flange and a front panel of the dispenser carton. The pair of locking tabs are received into flap apertures of the pair of flaps. A pair of triangular gaps separate a portion of a back panel of the dispenser carton from left and right side panels to bias the pair of locking tabs against stops of the pair of flaps. A bottom panel of the dispenser carton includes a bottom aperture.

Abstract: A raster scanning x-ray source can be light and small, and can have high resolution. A raster-assembly can be attached directly to and can encircle an x-ray tube. The raster-assembly can adjoin or can be very close to the x-ray tube, resulting in a small and lightweight scanning x-ray source. X-rays can backscatter back into the x-ray tube instead of into a detector, thus improving resolution of the resulting image. A voltage-multiplier, which can be used with the x-ray source, can include separate voltage-multiplier-stages in a stack.

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.

A viewport is established anchored to a first location on the first real-world object and a first image showing a first virtual view of the hidden portion of the occluded object as it would be seen from the first position of the DHR through the viewport is presented on the DHR overlaid on a first view of the first real-world object.
