Abstract: Systems and techniques for removing a sound recording from an audio recording (e.g., an audio recording embedded in a media file) are presented. The system can include an identification component, a first subtraction component and a second subtraction component. The identification component identifies a sound recording in a mixed audio recording. The first subtraction component determines a local linear transformation of the sound recording and subtracts the local linear transformation of the sound recording from the mixed audio recording to generate a new mixed audio recording. The second subtraction component compares one or more segments of the sound recording with one or more corresponding segments of the new mixed audio recording and reduces a power level of the new mixed audio recording based at least in part on correlation of the one or more corresponding segments with the one or more segments.

The system determines the wind drag and/or parasitic energy loss for each of plural, different locations along the one or more routes, visually presents the wind drag and/or parasitic energy loss for each of the different groups of vehicles, and/or determines the selected group of the one or more vehicles from the different groups of vehicles for travel along the one or more routes to achieve the desired outcome based on the wind drag and/or parasitic energy loss that is determined.

Abstract: A method and system of a machine learning architecture for predictive and preventive maintenance of vacuum pumps. The method includes receiving one of a motor sensor data and a blower sensor data over a communications network. The motor sensor data is classified into one of a vacuum state sensor data and break state sensor data. The vacuum state sensor data is analyzed to detect an operating vacuum level and an alarm is raised when the vacuum state sensor data exceeds a pre-defined safety range. Vacuum break data is classified into one of a clean filter category and clogged filter category and an alarm is raised if an entry under the clogged filter category is detected. The blower sensor data in association with the motor sensor data is analyzed based on machine learning to detect one of a deficient oil level and a deficient oil structure.

Abstract: The disclosed technology includes a system and method for selecting highlight media clips and posting the highlight media clips to social media platforms. In one implementation, a method includes receiving, during a live event, a selection of a point of interest (POI) in a media stream of the live event, the POI corresponding to a reference time during the live event, inserting into the media stream POI timing metadata indicating the reference time of the POI, and transcoding the media stream into data segments responsive to inserting the media stream POI timing metadata, each data segment corresponding to a presentation time stamp (PTS). The method may include selecting a data segment of the transcoded data segments, the selected data segment corresponding to a PTS mapped to the reference time and generating a media clip containing the selected data segment for presentation over a communications network during the live event.

The surgical implant includes a hemispherical cup with a plurality of equidistant apertures extending through the cup, and a ribbed, elongated stress-diffusion element, i.e., a stem, extending from the cup. The stem is formed to extend from and be oriented with respect to the cup based on whether the surgical implant is to be used on a left side of the patient, i.e., a left acetabulum, or a right side of the patient, i.e., a right acetabulum, for reconstruction of the segmental acetabular defect.

Abstract: The present disclosure relates generally to systems and methods for recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A system includes a reactor that receives and mixes a lead-beating material waste, a carboxylate source, and a recycled liquid component to form a leaching mixture yielding a lead carboxylate precipitate. The system also includes a phase separation device coupled to the reactor, wherein the phase separation device isolates the lead carboxylate precipitate from a liquid component of the leaching mixture. The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling, system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component.

Abstract: In an electrified transmission, motor leads are electrically connected to inverter leads by being squeezed between a compressible limiter on a terminal base and a prong of a cover plate. Several such connection are accomplished by installation of the cover to an inverter housing. This method reduces the number of assembly steps and is more robust to variations in the positions of the leads. The terminal base may be part of an inverter module within the inverter housing.

Abstract: Systems, devices, and methods for eyebox expansion in wearable heads-up displays (WHUD) are described. A WHUD includes a support structure, a scanning laser projector (SLP), a split mirror, an optical splitter, and a holographic combiner. When the WHUD is worn on the head of a user the holographic combiner is positioned in a field of view of the user. The SLP scans light signals onto the split mirror which reflects the light signals onto the optical splitter. The optical splitter redirects the light signals towards the holographic combiner such that subsets of the light signals originate from spatially-separated virtual positions. The holographic combiner redirects the light to the eye resulting in spatially-separated exit pupils. The spatial separation of the exit pupils results in an expanded eyebox. The indirect path of light from SLP to optical splitter enables a smaller and therefore more aesthetically desirable design for the WHUD.
