Abstract: A data stream, such as a video stream, may comprise one or more event trigger messages indicating an upcoming event in the stream. The time (e.g., pre-roll time) between the event trigger message and its corresponding event may be modified, based on rules, to provide a network operator, service provider or downstream recipient more (or less) time to prepare for the event. This may be accomplished by moving the event trigger to an earlier (or later) location in the stream, and/or editing the event trigger to indicate the different pre-roll time.

Abstract: A method for determining a risk of decompensated heart failure in a user includes receiving a first set of data that is fixed with respect to time. A machine-learning model generates one or more initial risk factors based on the first set of data. A second set of data for the user that dynamically updates over time is received from a wearable cardiovascular physiology monitor. The machine-learning model is used to generate dynamic data classifiers based on the one or more initial risk factors. Aggregate risk scores for the user are then indicated based on an evaluation of the second set of data against the dynamic data classifiers. In this way, static electronic medical records may be combined with dynamic, real-time data from wearable cardiovascular physiology monitors to provide an accurate and continuously updating risk of decompensated heart failure for a user.

Abstract: The various implementations described herein include methods and systems for determining device leadership among voice interface devices. In one aspect, a method is performed at a first electronic device of a plurality of electronic devices, each having microphones, a speaker, processors, and memory storing programs for execution by the processors. The first device detects a voice input. It determines a device state and a relevance of the voice input. It identifies a subset of electronic devices from the plurality to which the voice input is relevant. In accordance with a determination that the subset includes the first device, the first device determines a first score of a criterion associated with the voice input and receives second scores of the criterion from other devices in the subset. In accordance with a determination that the first score is higher than the second scores, the first device responds to the detected input.

Abstract: Disclosed herein includes a system, a method, and a device for managing energy detection thresholds. A device can perform an energy detection (ED) measurement of a channel, comparing against a defined ED threshold function, so as to determine if the channel is occupied. The device can perform a measurement of a channel indicative of a power level of signals detected in the channel. The device can compare the measurement to a threshold having a value that is a continuous monotonic function having a sloped region between a first region having a first constant value and a second region having a second constant value. The sloped region can include a function of a maximum transmit power of the device and at least one of the first constant value or the second constant value. The device can determine, responsive to the comparison, whether the channel is occupied or unoccupied.

Abstract: Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for generating a three-dimensional (3D) geometry of a room from a panorama image of the room. An apparatus includes processing circuitry that determine two-dimensional (2D) positions of wall corner points of the room in the panorama image based on a user input. Each wall corner point is in one of a floor plane or a ceiling plane of the room. The processing circuitry calculates 3D positions of the wall corner points based on the 2D positions of the wall corner points, a size of the panorama image, and a distance between the floor plane and a capture position of a device capturing the panorama image, determines a room layout based on an order of the wall corner points, and generates the 3D geometry based on the room layout and the 3D positions of the wall corner points.

Abstract: A midboard cable connector assembly with a board connector and a cable connector. The board connector has terminals precisely positioned with respect to engagement features. A cable connector likewise has terminals precisely positioned with respect to complementary engagement features. When the connectors are pressed together for mating, the terminals of one or both connectors deform, generating a force that separates the connectors until the engagement features engage and block further backward motion. As the mating position is defined by the locations of the engagement features, the connectors can be designed with low over travel and a resulting short stub length, which promotes high frequency performance. High frequency performance is further promoted by a ground conductor interconnecting the beams forming mating contact portions of ground terminals, reducing the length of unconnected segments and by a cable clamp plate with complaint compression features that reduce distortion of the cables.

Abstract: A light detection and ranging (LIDAR) system includes a LIDAR measurement unit, a reference measurement unit, and a phase cancellation unit. The LIDAR measurement unit estimates a time for which a laser beam travels. The reference measurement unit determines a phase of a laser source. The phase cancellation unit identifies phase noise and cancels the phase noise from the laser beam, at least partially based on the phase of the laser source and the time for which the laser beam travels. The denoised signal is used to determine the range between a laser source and a target.

Abstract: Systems and methods for managing network devices include performing clustering operations for network devices based on attributes of the network devices. By comparing the results of subsequent clustering operations, changes in network device attributes can be readily identified and any network devices for which attributes have changed may be subject to further investigation or remedial action (e.g., blocking traffic to/from the network device). Clustering may also be used to conduct an inventory of network devices by identifying groups of network devices that have similar attributes.

Abstract: In some embodiments, a method receives a first set of probabilities mapping a behavior to a user for a set of behaviors in a video delivery system. A first part of a model is used to predict the first set of probabilities.

Abstract: Systems and methods are provided for continuously monitoring a user to determine when cardiovascular events are likely occurring and to responsively provide a prompt to a user to engage in additional physiological assessment of the putative cardiovascular event. Additional assessment can include the user engaging an additional sensor to provide signals that are more accurate, lower noise, or otherwise improved relative to a continuously-monitoring sensor used to initially detect the cardiovascular event. Detection of cardiovascular events includes using a cardiovascular classifier to determine, based on the output of such a continuously-monitoring sensor, whether the event is likely occurring. Such a classifier can be received from a cloud computing service or other remote system based on sensor outputs sent to such a system.

Abstract: Magnetic latching valves for a vehicle engine have a housing having a first port and a second port in controlled fluid communication with one another. The housing encloses a linearly translatable armature seated within a solenoid and connected to a primary poppet valve. The armature is movable between an open position and a closed position, respectively, after a pulse of voltage to the solenoid and is in an unpowered state thereafter. A permanent magnet is fixedly seated in a position to magnetically latch the armature in a fully open position. A spring is seated to bias the primary poppet valve closed when the armature is in the closed position. The spring has a spring rate that mechanically relieves pressure by opening the primary poppet valve a distance less than the fully open position when the spring force is exceeded, thereby also allowing flow in the primary flow direction.
