Domain assist processor-peer for coherent acceleration
Examples herein describe a peripheral I/O device with a domain assist processor (DAP) and a domain specific accelerator (DSA) that are in the same coherent domain as CPUs and memory in a host computing system. Peripheral I/O devices were previously unable to participate in a cache-coherent shared-memory multiprocessor paradigm with hardware resources in the host computing system. As a result, domain assist processing for lightweight processor functions (e.g., open source functions such as gzip, open source crypto libraries, open source network switches, etc.) either are performed using CPUs resources in the host or by provisioning a special processing system in the peripheral I/O device (e.g., using programmable logic in a FPGA). The embodiments herein use a DAP in the peripheral I/O device to perform the lightweight processor functions that would otherwise be performed by hardware resources in the host or by a special processing system in the peripheral I/O device. |

Managing shared resources in a distributed computing system
A distributed computing system includes several partitions that each contain a separate copy of shared resources that receive modifications via behaviors and transactions specified by a user.

If a behavior or transaction fails while modifying a copy of a shared resource, the transaction manager prevents the behavior or transaction from modifying the remaining copies and preempts results from the failed behavior or transaction. The transaction manager reestablishes a consistent state across shared resources by rolling back the failed behavior or transaction, reverting each copy of the shared resources to its state prior to executing the behavior or transaction. |

Scanning probe microscope
When trace image data is obtained while a probe is used to scan a region on a sample in a forward direction and retrace image data is obtained while the same region is scanned in the reverse direction, a deviation information storage unit stores deviation detected by a deviation detection unit. This deviation is an indication of the difference between the distance between the probe and the sample and a target value for the distance at a given point in time. An image data selection unit compares the deviation during forward scanning and the deviation during reverse scanning for each measurement point, selects the image data obtained during scanning that has the smaller deviation, and stores the same to a storage region of an image data storage unit as selected image data. |

Hyperbaric power plant
The hyperbaric load control for a power plant is an energy storage device used to regulate the tangent velocity of a gas turbine. Specifically, the hyperbaric load control for a power plant: a) releases previously stored energy in the form of supplemental electrical energy to compensate for an energy deficit created by an operating condition where the electrical energy demanded by the electric load is greater than the energy provided by the gas turbine; and, b) absorbs and stores the excess energy created by an operating condition where the energy transferred to the electric generator from the gas turbine is greater than the electric energy demanded by the electric load. The hyperbaric load control for a power plant comprises an electric motor, a compressor, a high pressure gas tank, a supplemental turbine, a supplemental electric generator, and a control system. |

Rotary engine with axially directly connected compression and power cylinders
A rotary engine with axially directly connected compression and power cylinders is disclosed, which includes a compression cylinder, a power cylinder, an intermediate cylinder wall located between the compression and the power cylinder to serve as a common inner-end wall of the two cylinders, and a combustion chamber unit fixed to a circumferential surface of the intermediate cylinder wall, so that the rotary engine has axially directly connected compression and power cylinders. A compression-side and a power-side rotational valve are separately fitted in two recessed end surfaces of the intermediate cylinder wall. The compression-side and the power-side rotational valve are provided with three L-shaped first and second openings, respectively. Compressed air-fuel mixture in the compression cylinder flows through the L-shaped first openings into the combustion chamber, and high temperature high pressure gas generated after explosion in the combustion chamber unit flows through the L-shaped second openings into the power cylinder. |

Supercharged internal combustion engine
An internal combustion engine is described. The internal combustion engine comprises a valve control which is configured to close inlet valves of the internal combustion engine at Miller or Atkinson closing times. An electrified exhaust-gas turbocharger of the internal combustion engine comprises an electric machine which is operable selectively as a motor or generator. A control unit operates the electric machine of the electrified exhaust-gas turbocharger as a motor in a first load range of the internal combustion engine and as a generator in a second load range which corresponds to greater loads of the internal combustion engine than the first load range. |

Apparatus for controlling the temperature of a vehicle component using an anti-icing unblocking unit
An apparatus for controlling the temperature of a vehicle component, in particular of an internal combustion engine, by way of a cooling apparatus of the vehicle using at least one moving air guide which controls a cooling air stream. The apparatus has an anti-icing unblocking unit which is designed in such a way that it can release the air guide which has been blocked by ice and/or snow, so that the slats or the like which serve as the air guide are fully operational again. To this end, the anti-icing unblocking unit is designed to melt the ice and/or the snow. |
