  • Publication number: 20240137153
    Abstract: A device may receive a PDCCH signal, may decode encoded bits of the PDCCH signal to generate coded bits, may reencode the coded bits, and may calculate a detection error probability of each coded bit at an output of soft demodulation. The device may calculate a channel decoding error probability that cyclic redundancy check bits are still attached to the coded bits, and may calculate an error probability of channel reencoding, of each coded bit, due to error propagation of polar decoding and reencoding. The device may calculate a probability density of a BMR associated with the coded bits, and may calculate a threshold based on the detection error probability, the channel decoding error probability, the error probability of channel reencoding, and the probability density of a BMR. The device may determine that the PDCCH signal is invalid based on the BMR being greater than the threshold.

  • Patent number: 11968595
    Abstract: A method of determining a physical location for an address. The method includes receiving from a first global positioning system on a vehicle a first set of global positioning data indicative of a vehicle location. The method may also receive from a second global positioning system on a portable electronic device a second set of global positioning data indicative of a portable electronic device location. The method may also receive a set of location metadata associated with a picture. The method determines a residence location from the first set of global positioning data, the second set of global positioning data, or the set of location metadata. The method then associates the physical location to the address.

  • Publication number: 20240124791
    Abstract: The invention relates to renewable hydrocarbons, and more particularly to biomass-based diesel fuel produced in a process including hydrodeoxygenation (HDO) of phenolic lipids. The process may generally include combining a phenolic lipid and a hydrocarbon diluent to provide a hydrocarbon-diluted phenolic lipid then subjecting the hydrocarbon-diluted phenolic lipid to hydrodeoxygenation in a reactor to provide a reactor effluent including a hydrodeoxygenated phenolic lipid. The hydrodeoxygenated phenolic lipid is separated from the reactor effluent.

  • Publication number: 20240124785
    Abstract: An improved method for removal of contaminants from low-value and waste fats and oils for the purpose of hydrodeoxygenation into diesel boiling range hydrocarbons. The method includes removing organically bound contaminants from fats, oils, and greases (FOG) by adding water to a contaminated FOG stream, subjecting the mixture to heat, and mixing to promote reaction between the water and the FOG. Then, separating a reacted FOG from the contaminants. The reacted FOG will result in reduced organically bound chlorine contaminants.
