Abstract

An example electronic device includes a display device, and a sensor to detect position data of a user of the electronic device. The position data indicates a position and orientation of the user relative to the display device. In addition, the electronic device includes a controller coupled to the sensor and the display device. The controller is to: receive the position data from the sensor; use a machine learning model and the position data to classify an interaction of the user with the electronic device in a first ergonomic category or a second ergonomic category; and adjust an angular position of a display device or an output from the display device responsive to a classification of the interaction in the first ergonomic category.

Abstract

An image acquisition device may include a processor and a memory including a shadow correction module. The shadow correction module may receive an input image having a shadow and convert the input image into a grayscale image. Further, the shadow correction module may determine a foreground element on the grayscale image having a maximum height. Furthermore, the shadow correction module may generate the shadow map by performing a morphological closing operation on the grayscale image using a structural element having a dimension corresponding to the maximum height. Further, the shadow correction module may generate an output image by compensating for the shadow in the input image using the shadow map.

Abstract

A method comprises determining a target CMYK value in a CMYK space by representing the CMYK space as a 1D K subspace, and a 3D CMY subspace indexed with: a depth parameter that can take a plurality of values, each constraining values of C, M and Y with respect to one another to define a respective surface in the CMY subspace; and a 2D coordinate that can take a plurality of coordinate values. Each coordinate value corresponds with a position in the surface defined by a depth parameter value. A first depth parameter value and a first K value are determined which satisfy a first criterion constraining one with respect to the other; and a first coordinate value is determined which, with the first depth parameter value and the first K value, corresponds to a first CMYK value satisfying a second criterion and which is identified as the target value.

Abstract

Examples include a method for mitigating decap in a printing system that comprises nozzles, in which printing data associated to a graphical representation and that comprise pixel data points are received. Some data points are associated with a corresponding nozzle and a corresponding direction of movement and at least one specific data point is associated with a specific direction of movement and a specific nozzle which has a decap time below a first predetermined threshold. The received printing data is modified by displacing the printing data of the specific data point in a direction opposite to the specific direction of movement in order to compensate for the decap time.

The present disclosure relates to a method of 3D printing a 3D printed object. The 5 method comprises printing a layer of a build material composition comprising a solution of a metal salt and a liquid carrier. An interconnected metal network is formed by reducing the metal salt in the printed build material composition. A further layer of the build material composition is printed over the interconnected metal network, and the metal salt in the further layer is reduced to form a further 10 interconnected metal network over the underlying interconnected metal network to provide a porous structure to the 3D printed object. By layering and joining interconnected metal networks one on top of another, porous regions may be constructed within the 3D printed part.

Disclosed is a sensor arrangement. The sensor arrangement comprises an electromagnetic radiation source to emit electromagnetic radiation, a photodetector to receive the electromagnetic radiation, and an electromagnetic-radiation-permeable element. An optical path extends from the electromagnetic radiation source to the photodetector. The electromagnetic-radiation-permeable element is rotatable over more than 360 degrees between the electromagnetic radiation source and the photodetector and relative to the optical path so that, when the element is in a second rotational position relative to the optical path a greater proportion of the optical path is occupied by the element than when the element is in a first rotational position relative to the optical path.
