  • Publication number: 20210326539
    Abstract: A multiplier has a MOSFET in a common source configuration. A MOSFET current source is coupled to a drain terminal of the MOSFET, An inverter has an input coupled to the drain terminal of the MOSFET. An output of the inverter gates two currents whose current magnitudes are proportional. A first capacitor has a first terminal coupled to a first of the two currents and a gate of the MOSFET and a second terminal grounded. A second capacitor has a first terminal coupled to a second of the two currents and a second terminal coupled to the first of the two currents. The multiplier is first reset by discharging a gate capacitance of the MOSFET and then allowing it to be recharged to a Vt comparator threshold after which a charge is removed from the gate terminal of the MOSFET reducing a voltage on the gate terminal below the Vt comparator threshold, causing the two currents to be enabled until the Vt comparator threshold reaches a previous Vt comparator threshold and the inverter turns off the two currents.

  • Publication number: 20210327284
    Abstract: Methods, apparatus, and articles of manufacture to provide improved engine load models are disclosed. An example apparatus includes a model generator to generate an engine load model for an engine using flight information, weather information, and manifest information to predict a load on the engine from an engine subsystem utilization modeled for a flight. The example model generator is to incorporate the engine load model into an engine model, the engine model representing engine behavior for the flight. The example model generator is to determine a first measure of thrust from the engine and a second measure of fuel flow to the engine using the engine model with the engine load model, the engine load model to modify engine behavior by the predicted load on the engine from the engine subsystem utilization.

  • Publication number: 20210326455
    Abstract: A virtual environment system for validating executable data using authorized hash outputs is provided. In particular, the system may generate a virtual environment using a virtual environment device, where the virtual environment is logically and/or physically separated from other devices and/or environments within the network. The system may then open a specified set of executable data within the virtual environment and perform a set of commands or processes with respect to the executable data. If the system determines that the executable data is unsafe to run, the system may generate a hash output of the executable data and store the hash output in a database of unauthorized executable data. In this way, the system may securely generate a repository of authorized and unauthorized hashes such that the system may ensure that unsafe executable data is blocked from being processed within a network environment.

  • Publication number: 20210325892
    Abstract: In various examples, a current claimed set of points representative of a volume in an environment occupied by a vehicle at a time may be determined. A vehicle-occupied trajectory and at least one object-occupied trajectory may be generated at the time. An intersection between the vehicle-occupied trajectory and an object-occupied trajectory may be determined based at least in part on comparing the vehicle-occupied trajectory to the object-occupied trajectory. Based on the intersection, the vehicle may then execute the first safety procedure or an alternative procedure that, when implemented by the vehicle when the object implements the second safety procedure, is determined to have a lesser likelihood of incurring a collision between the vehicle and the object than the first safety procedure.

  • Publication number: 20210327118
    Abstract: A system and a method are disclosed for ray tracing in a pipeline of a graphic processing unit (GPU). It is determined whether a ray bounce of a first ray intersects a first primitive that is the closest primitive intersected by the ray bounce. The first ray is part of a first group of rays being processed by a first single-instruction-multiple-data (SIMD) process. The first ray is assigned by a sorting or binning unit to a second group of rays based on the intersection of the first primitive. The second group of rays is processed by a second SIMD process. The first ray is assigned to the second group of rays based on a material identification of the first primitive, an identification of the first primitive intersected by the ray bound of the first ray, a pixel location, and a bounce number of the ray bounce intersecting the first primitive.

  • Publication number: 20210327429
    Abstract: Methods, systems, and related products that provide emotion-sensitive responses to user's commands and other utterances received at an utterance-based user interface. Acknowledgements of user's utterances are adapted to the user and/or the user device, and emotions detected in the user's utterance that have been mapped from one or more emotion features extracted from the utterance. In some examples, extraction of a user's changing emotion during a sequence of interactions is used to generate a response to a user's uttered command. In some examples, emotion processing and command processing of natural utterances are performed asynchronously.
