  • Publication number: 20240059986
    Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a specific type of zeolite based catalyst which has been found to provide high conversion with minimal iso-paraffin products. In one embodiment, the zeolite is of the framework PWO. The reaction conducted in the presence of the zeolite based catalyst produces an n-paraffin rich product that needs no separation step before being fed to a steam cracker to produce lower olefins.

  • Patent number: 11875681
    Abstract: Drive envelope determination is described. In an example, a vehicle can capture sensor data while traversing an environment and can provide the sensor data to computing system(s). The sensor data can indicate agent(s) in the environment and the computing system(s) can determine, based on the sensor data, a planned path through the environment relative to the agent(s). The computing system(s) can also determine lateral distance(s) to the agent(s) from the planned path. In an example, the computing system(s) can determine modified distance(s) based at least in part on the lateral distance(s) and information about the agents. The computing system can determine a drive envelope based on the modified distance(s) and can determine a trajectory in the drive envelope.

  • Patent number: 11809178
    Abstract: A method for autonomously operating a driverless vehicle along a path between a first geographic location and a destination may include receiving communication signals from the driverless vehicle. The communication signals may include sensor data from the driverless vehicle and data indicating occurrence of an event associated with the path. The communication signals may also include data indicating that a confidence level associated with the path is less than a threshold confidence level due to the event. The method may also include determining, via a teleoperations system, a level of guidance to provide the driverless vehicle based on data associated with the communication signals, and transmitting teleoperations signals to the driverless vehicle. The teleoperations signals may include guidance to operate the driverless vehicle according to the determined level of guidance, so that a vehicle controller maneuvers the driverless vehicle to avoid, travel around, or pass through the event.

  • Patent number: 11783916
    Abstract: In acquisition of spatial transcriptomic information, a plurality of images representing a common field of view of a sample are obtained and registered. Each pixel of the registered images is decoded by identifying a code word from a plurality of code words in a code book that provides a best match to data values in the plurality of registered images for the pixel. For each code word identified as a best match and each pixel, whether a bit ratio for an image word for the pixel meets a threshold for the code word is determined. The image word is formed from the data values in the plurality of registered images for the pixel. For at least one pixel that is determined to meet the threshold, a gene associated with the code word is determined. Pixels for which the bit ratio does not meet the threshold are screened.
