  • Publication number: 20250143374
    Abstract: An apparatus is arranged to heat smokable material to volatilize at least one component of the smokable material. In one exemplary embodiment, the apparatus has a housing and a plurality of heater segments longitudinally arranged within the housing for heating smokable material contained within the apparatus. At least one heater segment is arranged so as to heat smokable material contained within the at least one heater segment more quickly than at least one other heater segment heats smokable material contained within the at least one other heater segment.

  • Patent number: 12294127
    Abstract: A stack current controller may be configured to request a current magnitude from a fuel cell. The current magnitude requested is based at least on a battery state of charge and is performed in a stepwise manner among a plurality of current magnitude steps, where each current magnitude step includes a debounce range with respect to at least one other current magnitude step. The stack current controller may be configured to control the fuel cell to output the requested current magnitude, determine an average current output by the fuel cell over a time period, and modify a current magnitude associated with one of the current magnitude steps based on the average current.

  • Patent number: 11990656
    Abstract: A stack current controller may be configured to determine a stack current request based on a state of charge of a battery, an error based on a difference between an actual coolant temperature and a coolant temperature setpoint, or both. A plurality of stack current levels may be implemented corresponding to different battery state-of-charge thresholds. The determined stack current magnitude may be the lowest current magnitude that provides sufficient heat to maintain a coolant temperature at the coolant temperature setpoint or within the coolant temperature threshold. The determined stack current magnitude may be the highest current magnitude that provides sufficient power while maintaining a coolant temperature at the coolant temperature setpoint or within the coolant temperature threshold.

  • Patent number: 6162162
    Abstract: A process for extracting a component from liquids using dense phase gases or supercritical fluids (dense phase solvent). The process contacts a liquid and the dense phase solvent in a rotating mixer to dissolve a desired fraction into the dense phase solvent to form a loaded solvent. Furthermore, the mixer separates the loaded solvent from the remaining raffinate. Then the rotating mixer discharges the loaded solvent and raffinate. Decreasing pressure on the loaded solvent converts the loaded solvent into a gas and the desired fraction to liberate the desired fraction from the gas.
