Abstract: A scoring system is disclosed for a shuffleboard table 2 having a sliding surface 4 on which a puck 6 can be thrown. A camera 26 is arranged to point in a direction 20 that is angled relative to the normal 30 of the sliding surface 4. A puck 6 can be thrown and a computer 32 can detect a moving object within a throwing zone 16. The computer 32 analyses whether the detected moving object corresponds to a valid puck. When all pucks are stationary on the sliding surface 4 the computer 32 can calculate a scare.

Abstract: The disclosure generally relates to a method of creating patterned metallic circuits (e.g., silver circuits) on a substrate (e.g., a ceramic substrate). A porous metal interlayer (e.g., porous nickel) is applied to the substrate to improve wetting and adhesion of the patterned metal circuit material to the substrate. The substrate is heated to a temperature sufficient to melt the patterned metal circuit material but not the porous metal interlayer. Spreading of molten metal circuit material on the substrate is controlled by the porous metal interlayer, which can itself be patterned, such as having a defined circuit pattern. Thick-film silver or other metal circuits can be custom designed in complicated shapes for high temperature/high power applications. The materials designated for the circuit design allows for a low-cost method of generating silver circuits other metal circuits on a ceramic substrate.

Abstract: A method is disclosed for automatically scoring a game of darts. The method involves obtaining an image of a dartboard (2) using three cameras (10), detecting a visual disturbance in the image, and identifying a validly thrown dart if the visual disturbance includes a moving phase with a maximum temporal duration and successive images of the dartboard which exhibit differences. The visual disturbance should also include a stationary phase when the dart has been embedded in the dartboard (2). The method also includes calculating a score for the validly thrown dart based on its stationary position relative to the dartboard. A lighting system for a dartboard is also disclosed where a LED strip light (14) is provided around a circumference of the dartboard and three spotlights (8) are provided above the dartboard.

Abstract: An adjustable field trimmer is provided, including a movable, wheeled carriage, a cutting unit pivotally mounted to the carriage and having combined drive system and a cutting head, a power head associated with the cutting unit for powering the cutting head, and a control system associated with the carriage and connected to the cutting unit so that the cutting unit is pivotable laterally relative to the carriage under operator control.

Abstract: The disclosure relates to a brazing method for joining substrates, in particular where one of the substrates is difficult to wet with molten braze material. The method includes formation of a porous metal layer on a first substrate to assist wetting of the first substrate with a molten braze metal, which in turn permits joining of the first substrate with a second substrate via a braze metal later in an assembled brazed joint. Ceramic substrates can be particularly difficult to wet with molten braze metals, and the disclosed method can be used to join a ceramic substrate to another substrate. The brazed joint can be incorporated into a solid-oxide fuel cell, for example as a stack component thereof, in particular when the first substrate is a ceramic substrate and the joined substrate is a metallic substrate.

Abstract: A trimmer head for a string trimmer mower, including a trimmer head housing having a string retention portion and a coupler portion rotatably attached to the string retention portion, the string retention portion having a first string retainer for releasably retaining a first cutting string. In addition, the string retention portion has a second string retainer for releasably retaining a second cutting string. The second string retainer is preferably circumferentially displaced on the string retention portion from the first string retainer. In a preferred embodiment, the first string retainer has a slidable clamp disposed in the interior and accessible from the exterior. The clamp is constructed and arranged for sliding relative to the base between a clamping position for selectively retaining the string in place through centrifugal force in the string retention portion, and a release position for user replacement of the first cutting string without tools.
