Abstract: A method includes selecting an entigen group from a knowledge database. The entigen group is a most likely meaning of a phrase of a string of words. An entigen of the entigen group corresponds to a selected identigen from a set of identigens regarding a word of the string of words. The set of identigens represent different meanings of the word. The method further includes identifying other entigen groups of alternate phrases having a similar most likely meaning from the knowledge database. The alternate phrases are different permutations of the string of words. The method further includes determining a dominant sentiment the other entigen groups and generating an updated clarifying entigen group based on the sentiment.

Abstract: A diffractive optical element (10) for a test interferometer (100) measures a shape of an optical surface (102). Diffractive shape measuring structures (16) are arranged on a used surface (14) of the element and generate a test wave (122) irradiating the surface when the element is arranged in the interferometer. At least one test field (18) several profile properties of test structures contained in the test field. The profile properties characterize a profile line of the test structures extending transversely with respect to the used surface and include a flank angle of the profile line, a profile depth and a depth of a microtrench in a bottom region of a trench-shaped profile of the test structures. The test field is arranged at one location of the used surface instead of the diffractive shape measuring structures such that the test field is surrounded by several diffractive shape measuring structures.

Abstract: The present invention relates to latency compensation for image processing devices. In order to assign overlay data to frames of a raw image stream (210), past frames within a selection of frames of the raw image stream are considered, which past frames already underwent image processing. A current frame of the raw image stream (210) is compared to the past frames contained in the selection of frames, and that one of the past frames is identified that is most similar to the current frame. Overlay data from the identified past frame are chosen and assigned to the current frame. Thus, the current frame can be presented together with the assigned overlay data chosen from the most similar past frame and without the need to wait for the result of a computationally expensive and time-consuming image processing of the current frame.

Abstract: The disclosure describes an improved drop-on-demand, controlled volume technique for dispensing resist onto a substrate, which is then imprinted to create a patterned optical device suitable for use in optical applications such as augmented reality and/or mixed reality systems. The technique enables the dispensation of drops of resist at precise locations on the substrate, with precisely controlled drop volume corresponding to an imprint template having different zones associated with different total resist volumes. Controlled drop size and placement also provides for substantially less variation in residual layer thickness across the surface of the substrate after imprinting, compared to previously available techniques. The technique employs resist having a refractive index closer to that of the substrate index, reducing optical artifacts in the device.

Additionally or alternatively, agents for raising the pH value of the pore solution of the cement stone can be added to the MgO- and/or olivine-based binder of the cement stone.

Abstract: The invention relates to a system and computer-implemented method for enabling correction of a segmentation of an anatomical structure in 3D image data. The segmentation may be provided by a mesh which is applied to the 3D image data to segment the anatomical structure. The correction may for example involve a user directly or indirectly selecting a mesh part, such as a mesh point, that needs to be corrected. The behaviour of the correction, e.g., in terms of direction, radius/neighbourhood or strength, may then be dependent on the mesh normal direction, and in some embodiments, on a difference between the mesh normal direction and the orientation of the viewing plane.

A second field of view is then established based on the anatomical model and the first field of view, wherein the first field of view functions as a reference field of view. The field of view is then switched from the first field of view to the second field of view.
