  • Publication number: 20190079764
    Abstract: A computer comprising one or more processors offering vector instructions may implement a direct convolution on a source data set. The source data set may be one-dimensional or multi-dimensional. For a given vector width, w, of the vector instructions, w consecutive data elements of the output data set are computed in parallel using vector instructions. For multi-dimensional data sets, multiple vectors of the output data set are computed for a single load of a set of vectors from the source data set. New vector instructions are disclosed to improve the performance of the convolution and to enable full utilization of the arithmetic logic units within the one or more processors.

  • Publication number: 20190003419
    Abstract: An engine waste heat recovery (WHR) system includes a turbocharger WHR portion, an exhaust WHR portion, an expander in the exhaust WHR portion, a condenser, valves, and a controller. The expander receives a working fluid in a superheated form and converts thermal energy in the working fluid into mechanical energy or electrical energy. The condenser condenses the working fluid for recirculation through the engine WHR system. The recuperator is fluidly coupled between the expander and the condenser to allow the working fluid to flow from the expander to the condenser. The recuperator transfers thermal energy to a flow of the working fluid from the turbocharger WHR portion. Each valve is fluidly coupled to one of the turbocharger WHR portion and the exhaust WHR portion. The controller is electrically coupled to the valves, and the controller selectively controls the valves to selectively circulate the working fluid through the engine WHR system.

  • Patent number: 10040439
    Abstract: A powertrain system employing multiple propulsion torque actuators is described. A method for controlling the powertrain system includes interpreting a driver request, including determining a driver torque request and a regenerative braking request based upon driver inputs to an accelerator pedal and a brake pedal. A desired request is determined based upon the driver torque request and the regenerative braking request. Torque limits for the powertrain system are coordinated based upon the desired request, the driver torque request, and a previous driver torque request to determine upper and lower output torque limits, and the upper and lower output torque limits are combined with system constraints to generate a final torque request. The final torque request is employed to determine torque commands for the propulsion torque actuators, and the propulsion torque actuators are controlled based upon the torque commands for the propulsion torque actuators.

  • Patent number: 9990307
    Abstract: Packet information is stored in split fashion such that a first part is stored in a first device and a second part is stored in a second device. A split packet transmission DMA engine receives an egress packet descriptor. The descriptor does not indicate where the second part is stored but contains information about the first part. Using this information, the DMA engine causes a part of the first part to be transferred from the first device to the DMA engine. Address information in the first part indicates where the second part is stored. The DMA engine uses the address information to cause the second part to be transferred from the second device to the DMA engine. When both the part of the first part and the second part are stored in the DMA engine, then the entire packet is transferred in ordered fashion to an egress device.

  • Patent number: 9975451
    Abstract: A powertrain system including an internal combustion engine, a transmission and an electric machine is described, and includes the electric machine rotatably coupled to a crankshaft of the internal combustion engine. The transmission is coupled to a driveline to transfer tractive torque and braking torque thereto. A method for controlling the electric machine includes determining a short-term axle torque capacity, a long-term axle torque capacity and a maximum regenerative braking stall torque capacity, and determining an operator request for braking. A preferred regenerative braking capacity is determined based upon the short-term axle torque capacity, the long-term regenerative braking capacity, the engine stall regenerative braking capacity and the operator request for braking. Torque output from the electric machine is controlled based upon the preferred regenerative braking capacity.

  • Patent number: 9960723
    Abstract: Disclosed examples include power conversion systems, computer readable mediums and methods for mitigating input filter resonance, in which a controller operates an active front end (AFE) rectifier in a first mode to turn a single rectifier switching device on and off and measures a filter voltage or current signal while all of the rectifier switches are off. The controller determines a resonant frequency based on a transient response of the measured voltage or current signal, and selectively adjusts a rectifier control parameter to mitigate filter resonance based on the resonant frequency.

  • Patent number: 9912577
    Abstract: In one embodiment, a controller device in a computer network domain learns border gateway protocol (BGP) egress peering segments from one or more border routers of the domain, and determines a selected flow to segment route via a particular egress peering segment, the selected flow from a given routing device within the domain to a given destination of a remote domain. As such, the controller device may then instruct the given routing device to segment route the selected flow via the particular egress peering segment. In another embodiment, an egress border router shares its BGP egress peering segments, and receives a flow to segment route. The egress border router may determine, from a segment route contained within the flow, to which particular egress peering segment of the border router to segment route the flow, and forwards the flow out of the domain via the particular egress peering segment.

  • Publication number: 20180015135
    Abstract: A composition includes a target pharmaceutical or biological agent, a solution containing the target pharmaceutical or biological agent, and substrate that is soluble in the solution. The substrate is capable of being solidified via a solidification process and the solidification process causes the substrate to become physically or chemically cross-linked, vitrified, or crystallized. As a result of the solidification process, particles are formed. The target pharmaceutical or biological agent within the solution retains proper conformation to ultimately produce a desired effect.
