Abstract: Systems and methods for smart communication for providing communication between users showing availability of users via an augmented reality avatar is provided. The system may determine availability by detection of motion and location of a user relative to a device. The system may also determine privacy video calling availability utilizing augmented reality avatars with facial expression tracking. The system may be directed to video communication devices configured for various actions such as, for example, video calling, streaming, gaming, and augmented reality.

Abstract: In some implementations, a method may include obtaining target fault data indicating a preselected fault for a vehicle having a hydrogen source. In addition, the method may include obtaining vehicle fault data indicating a fault of the vehicle. The method may include identifying a match between the fault and the preselected fault. Moreover, the method may include purging, in response to the identifying the match, hydrogen from the hydrogen source so as to reduce consequences of a battery thermal event by reducing the likelihood of a hydrogen-fueled fire.

Abstract: A photoresin formulation for volumetric additive manufacturing contains a photo-curable mixture of: a monomer (e.g., an acrylate-based monomer); a photoinitiator; a polymerization inhibitor (e.g., molecular oxygen (O2)); and, a reducing agent reactive with a free radical species (e.g., a peroxyl radical) formed from the polymerization inhibitor. The reducing agent permits faster printing of objects from the photoresin formulation in a volumetric additive manufacturing process to produce 3D objects of high fidelity.

Abstract: A technique for improving the retention force between a connector (10, 11, 12, 13, 14, 15, 16, 17, 100, 101) and a spacer (1) for insulating glass units is disclosed.

Abstract: A spacer for retaining a cladding element on a building element in a spaced apart relationship has a constant cross-section in its longitudinal direction. The spacer is an at least substantially hollow structure having at least one external wall enclosing an interior space. At least one fastener insertion path extends through the interior space. The fastener insertion path is capable of holding a fastener disposed therein prior to mounting the spacer and cladding element on the building element. The spacer preferably comprises planar surfaces on opposite sides thereof that are configured to abut the cladding element and the building element, respectively.

Abstract: The invention relates to a method for filtering measurement signals by way of wavelet filtering, wherein the signals are first transferred to the wavelet domain by way of a wavelet transform, are subjected to threshold analysis, and the threshold values can then be varied in the wavelet domain commensurate with the respective measurement situation. The measurement signals are filtered by a plurality of filters arranged in segmentation levels and a statistical parameter is calculated based on an adjustable number of already calculated wavelet coefficients of a segmentation level and is then multiplied with a value that can be adjusted.

Abstract: A method for nondestructive testing of the pipes for detecting surface flaws using magnetic leakage flux is disclosed. With of the method, flaws can be detected and analyzed in near-real-time while the pipe is produced. The data obtained with inductive coils, Hall sensors or GMR sensors are digitized, the digital data are buffered in a first memory, and a subset of the digital data are copied into a second memory. The copied data are transformed with a wavelet transformation and the resulting wavelet coefficients are filtered and/or modified. In an alternative embodiment, the digital data can be continuously supplied to a routine for wavelet transformation, which is performed using cascaded digital signal processing routines. The evaluated variable is compared with a reference value, wherein a determined flaw-based signal can be unambiguously associated with the position of the flaw.

Abstract: A method for nondestructive testing of the pipes for detecting surface flaws is disclosed. With of the method, flaws can be detected and analyzed in near-real-time while the pipe is produced. The data obtained by ultrasound sensors are digitized in a time window following a trigger pulse, and the digitized data are processed in a digital processor, for example a DSP, using wavelet transforms. The evaluated quantity is compared with a reference value, wherein a determined flaw-based signal can be uniquely associated with the flaw located on the pipe surface.

Abstract: The present invention pertains to a method for the nondestructive testing of pipes made of ferromagnetic steel by means of a stray flux, in which the pipe, which is moving in the longitudinal direction and alternatively additionally rotating, is magnetized by a constant field, and the generated magnetic flux is transmitted into the pipe in a contactless manner, and the flaws that are located in the near-surface area of the outer or inner surface of the pipe bring about magnetic stray fluxes, which emerge from the pipe surface and are detected by means of sensors. The amplitudes, preferably of the horizontal field component of the magnetic stray flux, which vary in the vertical direction, are detected, on the one hand, at a near-surface distance from the pipe outer surface, and, on the other hand, at a distance lying further remotely therefrom, and the detected signals are related to one another.
