Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.

A nasal dilator comprises a laminate of vertically-stacked layers that form a unitary truss. The truss features end regions that engage outer wall tissues of a user's nasal passages, joined by an interconnecting region that traverses the bridge of the nose. The dilator acts to stabilize nasal outer wall tissues and prevent them from drawing inward during breathing. Dilator components are sized and shaped to engage the nose and provide effective dilation, and to facilitate lateral and longitudinal registration during manufacture, while reducing material waste. Methods of manufacture include progressive steps to fabricate and assemble components into finished devices. Some partially-assembled embodiments include a final assembly step performed by the user to create a dilator with a customized truss length.

A knife includes a handle that includes a gripping surface; a blade slide positioned in a recess of the handle that extends from an opening of the handle through a cavity within the handle; a blade coupled to the blade slide near a proximal end of the blade and extending through the recess and into the opening when the blade slide is in the retracted position; and a guide coupled to the blade near a distal end of the blade opposite the proximal end, the guide including a contoured surface configured to engage a workpiece to extend the blade slide a distance from the retracted position to an extended position such that the blade is extended from the opening of the handle, the blade slide biased to move from the extended position to the retracted position.

An automated food processing machine receives a whole fruit or vegetable and presses it through a blade set to form slices or wedges. The machine includes a controller coupled to various components including linear motion actuators, a user interface, and sensors. One motion actuator coupled to a slitting blade. Another motion actuator is coupled to a ram. In response to an input the controller activates the motion actuators in a sequence including (1) linear motion of the slitting blade to form a slit in the whole fruit or vegetable and (2) linear motion of the ram to press the whole fruit or vegetable through a blade set to form the slices or wedges.

Tools and methods are provided for scarfing rotor blade segments. A rotor blade segment includes a pressure side and a suction side. A tool includes a first guide configured for mounting on one of the pressure side or the suction side, the first guide including a first curved rail and a second curved rail spaced from the first curved rail. The tool further includes a second guide movably coupled to the first guide at a scarf angle, the second guide including a guide rail extending between and movable along the first curved rail and the second curved rail. The tool further includes a cutting device movably coupled to the second guide, the cutting device movable along the guide rail and operable to remove material from the one of the pressure side or the suction side.

An acoustic wave device comprises a substrate and an acoustic wave element on one main surface of the substrate. Side surfaces of the substrate comprises a protruding portion which protrudes out at a side of an another main surface closer than a side with the one main surface side.

Embodiments provide a pre-cut infeed system for a machine center, such as an edger. A pre-cut infeed system may include an infeed, one or more saws arranged along the infeed, and a scanner optimizer system. The scanner optimizer system may scan a workpiece and determine whether greater value can be obtained from the workpiece by cutting the workpiece transversely into two or more pieces upstream of the machine center. If so, the workpiece may be cut transversely by the saw(s) positioned along the infeed, and the cut pieces may be fed sequentially into the machine center.

A knife includes a handle that has a surface that may be gripped by a user of the knife. The handle includes an extendable blade that has a cutting portion and a non-cutting portion. The guide is attached to the blade independent of an engaging contact between the guide and the handle. The guide exposes the cutting portion of the blade and cover at least part of the non-cutting portion of the blade.
