Abstract: An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.

Abstract: An alignment apparatus (the tool) of the present invention includes a pair of bracket devices for rigidly holding shafts. As the shafts are secured to the bracket devices with chains, sensors of one of the bracket devices are exposed to an extension beam of the other bracket device thereby defining gaps or distances between the extension beam and the sensors. If offset is determined between the distances because one shaft is misaligned relative the other shaft, the sensors send signal to a mobile device, thereby informing a user about misalignment between the shafts.

Abstract: A wave energy converter comprises an energy absorption unit arranged to absorb energy generated by movements of water, a power smoothing unit, a power generation unit and an energy storage device, these units being adapted to cooperate to achieve a smooth power output from the power generation unit. The power smoothing unit is arranged to accumulate energy from the energy absorption unit in the energy storage device when the energy absorption unit absorbs more power than the power generation unit generates and to release energy from the energy storage device to the power generation unit when the energy absorption unit absorbs less energy than the power generation unit generates.

Abstract: A wave energy converter (10) comprises an energy absorption unit (100) arranged to absorb energy generated by movements of water when the wave energy converter is arranged in a pool of water, an energy accumulation unit (200) connected to the energy absorption unit, and a power generation unit (300) connected to the energy absorption unit. The energy accumulation unit is arranged to accumulate energy from the energy absorption unit when the energy absorption unit absorbs more power than the power generation unit generates and to dissipate energy to the power generation unit when the energy absorption unit absorbs less power than the power generation unit generates. By providing hydraulic components in these units, an efficient and flexible wave energy converter is provided.

Abstract: A chipper knife that is adapted to be mounted in chippers which have a rotatable tool, in the form of a disc, drum or frustoconical member, on which a plurality of such chipper knives are mounted has at least a first side having a raw, unworked surface or working stripes extending in the longitudinal direction of the chipper knife, substantially parallel to the cutting edge which also has a cutting edge portion extending inwardly from the cutting edge and terminating in a shoulder extending parallel to the cutting edge to provide a clearance step on the knife behind the shoulder with respect to the adjacent knife surface, which edge portion also has working stripes formed therein transverse that cutting edge portion and at an angle to the cutting edge.

Abstract: A vehicle seat assembly includes a seat body that is configured for attachment to a floor surface of a vehicle. The seat body includes a seat back that is connected to a seat bottom. The seat back has a seat back frame and the seat bottom has a seat bottom frame. An electric component is mounted to the seat body. A first mounting member attaches the electric component to one of the seat back frame and the seat bottom frame. In this vehicle seat assembly, the first mounting member is configured to flex such that the electric component can move in a direction that is generally perpendicular to a plane of the one of the seat back frame and the seat bottom frame.

Abstract: A vehicle seat for use with a ventilation system is provided. The seat includes an air-conducting layer, which may be provided underneath a seat surface. The air-conducting layer may cooperate with intake spots in a seat portion. The intake spots may be placed on lines substantially corresponding to the position of the legs of a person sitting in the seat and/or on a line extending substantially along the spine of a person sitting in the seat.

Abstract: This invention relates to a vehicle seat assembly having a lower seat assembly and a seat back assembly, the lower seat and seat back assemblies having an exterior surface and an interior region. The vehicle seat includes a ventilation system configured to move air through body-side openings in the exterior surface, the ventilation system comprising a fan and one or more fan openings, the fan openings providing fluid communication between the fan and an exterior of the seat assembly through the exterior surface. The vehicle seat also includes a flexible noise cover, mounted on the vehicle seat assembly, defining the fan openings.

Abstract: The invention relates to a chipper knife of the type that is adapted to be mounted in chippers which have a rotatable tool, in the form of a disc, drum or frustoconical member, on which are mounted a plurality of such chipper knives to provide, during rotation of the tool and simultaneous feeding of pieces of wood to the same, material-cutting working or disintegrating of the pieces of wood into chips by means of at least one cutting edge (1, 1?). At least a first side of the chipper knife has a raw, unworked surface or working stripes in the longitudinal direction of the chipper knife, that is substantially parallel to the cutting edge. This first side also has a thickened cutting edge portion (5, 5?) in the area next to the cutting edge, which edge portion has working stripes in the transverse direction of the chipper knife, at an angle to the cutting edge. The invention also relates to a method of manufacturing such a chipper knife.

Abstract: A method of creating a user menu (AM1) in a display (2, 22) in a user unit (1, 21, 41). The user menu (AM1) denotes an accessory unit (5, 25a) connected to the user unit (1, 21, 41). Information (I1, I2) is stored in a menu storage unit (3, 23) in the user unit (1, 21). The information (I1, I2) is used to create a standard menu (SM1). The accessory unit (5, 25a) is connected to the user unit (1, 21), and a menu selection code (MCODE) is sent from the accessory unit (5, 25a) to the menu storage unit (3, 23) in the user unit (1, 21). A standard menu (SM1), which corresponds to the menu selection code (MCODE), is pointed out in the menu storage unit (3, 23). The pointed out standard menu (SM1) is adapted to a user menu (AM1) corresponding to the menu selection code (MCODE), and the user menu (AM1) is activated in the display (2, 22).
