Granular replication of volume subsets
Data is replicated on a backup node, where the granularity of the replication can be less than a full volume. A data consistency group comprising a subset of data for a volume is defined for a primary node. A set of differences for the data consistency group is sent to a backup node. The backup node creates change logs in response to receiving the set of differences. In response to receiving a request to access a file having data in the data consistency group, the backup node creates a clone of the file. The backup node determines whether an update to a data block of the file exists in the change logs. In response to determining that the update to the data block exists in the change logs, the backup node updates a copy of the data block for the cloned file with data in the change logs. |

This may be advantageous because storing the data in shared cache can reduce or avoid having multiple copies in different private caches and can reduce the cache coherency overhead involved to keep copies in the private caches in sync. |

Time-to-digital converter using voltage as a representation of time offset
A time-to-digital converter (TDC) uses voltage as a representation of time offset. A voltage change is induced over a time period from a start signal to a stop signal. The final voltage is then measured, and the voltage measurement is mapped to a time value representing the time between the start signal and the stop signal. The voltage change can be increasing or decreasing, e.g., by charging or discharging a capacitive circuit between the start signal and the stop signal. The voltage can be measured using an analog-to-digital converter (ADC) or other voltage measurement circuit. The voltage measurement can be mapped to the time value in any manner, such as, for example, using a transfer function or using a mapping table that provides a time value for each possible voltage measurement value. |

Thermal cracker for combustible and flammable liquids for engines
The present invention relates to a combination of components suitable to break down liquid fuels into short chain molecules and gaseous states of matter by heating and pressurizing the combustible/flammable liquids to the point where they phase change into a supercritical fluid, then releasing some fluid as needed into a vapor accumulation tank that has a lower pressure. This subsequent drop in pressure phase changes the fluid from a supercritical state into a consistent and safe gaseous state. From there, the fuel can be delivered to the engine via direct injectors, gaseous fuel carburetors, or a regulating valve such as a needle valve. Because gaseous fuels readily homogenize with intake air and oxidizers, the present invention allows any engine to cleanly, reliably, and consistent use any fuel without adjustment.
