Abstract: Configurable product return determination includes maintaining product profiles indicating updated configurations of products and their components, building and training a set of models configured to identify products that are expected returns, predict retention times for such products, and determine, based on quality indicators of the products and on requirements for reusability of components, reusable components of the products, and, using the set of models and a product profile of a product in use, determining that the product in use is expected to be returned in the future and an expected timeframe of the return of the product in use, and determining one or more components, of a set of components of the product in use, that are reusable upon return of the product in the future.

Abstract: A system for presenting audio content to a user. The system comprises one or more microphones coupled to a frame of a headset. The one or more microphones capture sound from a local area. The system further comprises an audio controller integrated into the headset and communicatively coupled to an in-ear device worn by a user. The audio controller identifies one or more sound sources in the local area based on the captured sound. The audio controller further determines a target sound source of the one or more sound sources and determines one or more filters to apply to a sound signal associated with the target sound source in the captured sound. The audio controller further generates an augmented sound signal by applying the one or more filters to the sound signal and provides the augmented sound signal to the in-ear device for presentation to a user.

Abstract: Techniques, which may be embodied herein as systems, computing devices, methods, algorithms, software, code, computer readable media, or the like, are described herein for comparing a set of metrics generated during a simulated user interaction with a website to metrics generated by observing real user interactions with the website. Simulated user interactions with a website can be used to diagnose a website's performance issues, but it can be difficult to determine whether the simulated interactions reflect the experience of real users. In addition, the simulated user interactions can be challenging to contextualize because the number of observed real user interactions may significantly outnumber the simulated interactions. A graphical user interface can help with the interpretation of these website interactions by using the real user interactions to properly contextualize the simulated results.

Abstract: A system for providing a bio-firewall for a medical device. The system includes a bio-firewall electronic processor configured to receive a processed network command from a device electronic processor. The bio-firewall electronic processor is also configured to determine whether the processed network command is associated with a cyberattack based on at least one rule. The bio-firewall electronic processor is also configured to, in response to determining that the processed network command is not associated with the cyberattack, enable transmission, via a non-networked communication interface, of the processed network command to a non-networked component. The bio-firewall electronic processor is also configured to, in response to determining that the processed network command is associated with a cyberattack, prevent transmission, via the non-networked communication interface, of the processed network command to the non-networked component.

Abstract: Techniques for determining personalized head-related transfer functions (HRTFs) using a head-mounted device and in-ear devices include: receiving, from a sensor array of the head-mounted device, a first sound signal associated with a sound from a sound source in a local environment of a user of the head-mounted device; determining that reverberation characteristics and spectral characteristics of the sound meet predetermined criteria based on the first sound signal; determining that the sound source is stationary within a time period; determining a relative location of the sound source with respect to the user; receiving, from an in-ear device in an ear of the user, a second sound signal associated with the sound from the sound source; and determining, based on at least the second sound signal, an HRTF or one or more parameters of the HRTF associated with the relative location of the sound source for the user.

Systems and methods are provided for receiving diagnostics data of a hydraulic fracturing completion of a wellbore, accessing a fracture formation model that models formation characteristics of fractures formed through the wellbore into a formation surrounding the wellbore during the hydraulic fracture completion with respect to surface variables of the hydraulic fracturing completion, selecting one or more subsurface objective functions from a plurality of subsurface objective functions for changing one or more of the formation characteristics of the fractures, and applying the fracture formation model based on the diagnostics data to determine values of the surface variables for controlling the formation characteristics of the fractures to converge on the one or more subsurface objective functions.

Abstract: A system is disclosed for using an audio time and level difference renderer (TLDR) to generate spatialized audio content for multiple channels from an audio signal received at a single channel. The system selects an audio TLDR from a set of audio TLDRs based on received input parameters. The system configures the selected audio TLDR based on received input parameters using a filter parameter model to generate a configured audio TLDR that comprises a set of configured binaural dynamic filters, and a configured delay between the multiple channel. The system applies the configured audio TLDR to an audio signal received at the single channel to generate spatialized multiple channel audio content for each channel of the multiple audio channel and presents the generated spatialized audio content at multiple channels to a user via a headset.

Abstract: Techniques are described for generating spatialized audio content based on head orientation information and torso orientation information obtained from a drift compensation system. The drift compensation system compensates for drift in measurements performed by an inertial measurement unit (IMU), based on biological constraints pertaining to a user. The head orientation information is applied to a first set of filters to generate intermediate audio content. In turn, the torso orientation information and the intermediate audio content are applied to a second set of filters to generate the spatialized audio content. The first set of filters includes one or more audio filters that receive an input audio signal corresponding to a left channel. The second set of filters includes one or more audio filters that receive an input audio signal corresponding to a right channel. The spatialized audio content includes separate output signals for the left channel and the right channel.

Abstract: A system for identifying and deleting records of hosts includes a local data manager. The local data manager identifies a discovery event associated with the host and a record type of record types, obtains, in response to identifying, all previously discovered records on the host associated with the record type from a host record repository, obtains discovered records associated with the record type and associated with the host, after obtaining all discovered records and previously discovered records, selects a previously discovered record of the previously discovered records, makes a determination that the previously discovered record does not match any discovered records of the discovered records and is not tagged with a soft delete tag or a hard delete tag, and in response to the determination, tags the previously discovered record with a soft delete tag, and notifies a data manager of modifications to the previously discovered records.

Abstract: A system can include a position sensor configured to output position data of a HWD. The system can include one or more processors configured to identify a first head angle of the HWD using the position sensor, generate an audio signal using the first head angle, identify a second head angle of the HWD using the position sensor, determine an angle error based at least on the first head angle and the second head angle, and apply at least one of a time difference or a level difference to the audio signal based at least on the angle error to adjust the audio signal. The system can include an audio output device configured to output the adjusted audio signal. By adjusting the audio signal using the angle error, the system can correct for long spatial update latencies and reduce the perceptual impact of such latencies for the user.
