A streaming data storage system provides for segment groups that facilitate the distribution of event traffic among storage entities.

Memory management method and apparatus for processing-in-memory
This application relates to a memory management method for maximizing processing-in-memory (PIM) performance and reducing unnecessary DRAM access time. In one aspect, when processing a PIM instruction packet, an instruction processing unit secondarily processes a request for access to a destination address at which read and write actions of an internal memory are likely to be sequentially performed. By secondarily requesting the destination address, a row address of an open page of the internal memory may match a row address to which a PIM instruction packet processing result is written back. Also, the instruction processing unit inside the PIM maintains memory write and read addresses that have previously requested. The instruction processing unit compares the address of a packet to be processed to the maintained previous memory address and informs a memory controller about the comparison result through a page closing signal. |

A nonlinear crystal comprising a first end face and an opposing second end face is described.

Vibrational circular dichroism spectroscopy
A vibrational circular dichroism (VCD) spectroscopy method and apparatus that can significantly reduce the measurement time needed to acquire a differential absorption spectrum compared to known approaches. A dual-comb is generated by superimposing the outputs from two quantum cascade laser sources, thus providing a third comb interferogram with beat frequencies higher than the polarization modulation frequency. Consequently, for each of the left and right circularly polarized light, the measurement signal measures transmission through the sample across the full wavelength range of interest during each period of the polarization modulation. A complete vibrational spectrum is thus acquired in each modulation of a polarization modulator, instead of only acquiring data for a single wavelength during each modulation of the polarization, as in dispersive or tunable laser VCD, or only a single Fourier component of the spectrum, as in Fourier transform VCD. |

A superordinate controlling device for a heat source system (1) including a plurality of heat sources, the superordinate controlling device being applied to the heat source system (1) and controlling heat-pump type chillers (2a) and (2b) and absorption-type chillers (2c) and (2d) in such a manner that a heat transfer medium leaving temperature that is the temperature of a heat transfer medium supplied to an external load (6) is equal to a setting temperature. The heat-pump type chillers (2a) and (2b) each have a higher Coefficient of Performance (COP) than that of each of the absorption-type chillers (2c) and (2d). The superordinate controlling device includes a heat transfer medium leaving temperature changing means for carrying out heat transfer medium leaving temperature control, by changing the heat transfer medium leaving temperatures of the heat-pump type chillers (2a) and (2b), when a post-change prediction value of each of the absorption-type chiller (2c) and (2d) predicted based on a supposition that the heat transfer medium leaving temperatures of the heat-pump type chillers (2a) and (2b) are changed exceeds a second underload stop threshold value at which the corresponding one of the absorption-type chiller (2c) and (2d) would have an underload stop. |

Fuel injector
A fuel injector for a gas turbine engine, the injector comprising a main fuel flow circuit and a pilot fuel flow circuit. The pilot fuel flow circuit comprises at least one convoluted pilot fuel flow passage extending continuously from a pilot fuel feed at an upstream end of the injector to a pilot fuel spray nozzle inlet. The at least one pilot fuel flow passage comprises at least two axially-extending portions extending between the upstream end of the injector towards a downstream end of the injector and joined by an elbow portion proximal the downstream end of the injector. In use, pilot fuel can flow in opposing axial directions within the at least two axially-extending portions, the axially-extending portions being in thermal communication with the main fuel flow circuit. |

Combustion analyzer with simultaneous carbon monoxide and methane measurements
A combustion analyzer configured to simultaneously detect the concentrations of oxygen, carbon monoxide and methane in a combustion process is provided. The combustion analyzer includes an oxygen sensor configured to detect the oxygen in the combustion process and generate a sensor signal indicative of the concentration of oxygen in the combustion process. The combustion analyzer further includes a dual carbon monoxide-methane sensor configured to operate at approximately 400° C. and provide a second sensor signal indicative of methane concentration and at approximately 300° C. to selectively provide a third sensor signal indicative of carbon monoxide concentration. The combustion analyzer finally includes a controller configured to receive the sensor signals, determine the concentration of oxygen, and generate a carbon monoxide concentration output and methane concentration output based on the dual carbon monoxide-methane sensor signals and the concentration of oxygen. |

Solid fuel burner and combustion device
This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle. |

Light circuit for imaging device
A medical imaging device having a bore 104 for receiving a patient during a medical imaging process and a ventilation channel 216 having an opening within the upper circumference of the bore for supplying cool air into the bore. At least one lighting circuit 210 with one or more LEDs is positioned within the ventilation channel 216 and is configured to illuminate the entire length of the bore 104. Air supplied from the ventilation channel 216 cools the lighting circuit 210 and prevents overheating effects within the lighting circuit that are caused by fields generated during the medical imaging process. The lighting circuit 210 comprises one or more filters, wherein the resonance frequency of the medical imaging device is within the stopband of the filters. |

Systems and methods for a heat sink
Embodiments disclosed herein describe systems and methods for heat sinks within light fixtures. In embodiments, the heat sink may be a passive system that creates a cross-flow thermal management system to dissipate large amounts of heat in a slim light fixture. Embodiments may utilize a series of wings assembled in a linear design that are positioned perpendicular to the length of the light fixture to preserve the cross-flow heat sink. |
