  • Patent number: 11965795
    Abstract: One variation of a method includes, during a first time period: detecting a direction of motion of a trailer; detecting a first force applied to a kingpin; detecting an incline angle of the trailer; calculating a first target preload force opposite the direction of motion and inversely proportional to the incline angle; and in response to the first force falling below the first target preload force, triggering a motor to increase torque output opposite the direction of motion. The method further includes, during a second time period: detecting a second force applied to the kingpin; detecting a decline angle of the trailer; calculating a second target preload force opposite the direction of motion and inversely proportional to the decline angle; and in response to the second force falling below the second target preload force, triggering the motor to increase torque output opposite the direction of motion.

    Abstract: One variation of a system includes a kingpin: arranged on a proximal end of the trailer; includes a sensor configured to output a signal representing lateral forces and longitudinal forces applied to the kingpin; and configured to couple to a tow vehicle. The system further includes an interface including a joystick and a kingpin interface configured to transfer forces, applied to the joystick, into the kingpin. The system also includes a controller configured to: access the signal from the sensor; based on the signal, calculate a magnitude of a force applied to the kingpin; calculate a first target speed of a first wheel of the trailer proportional to the magnitude; calculate a second target speed of a second wheel of the trailer proportional to the magnitude; and serve the first target speed and the second target speed to a drive system arranged on a distal end of the trailer.

  • Publication number: 20230249184
    Abstract: Fluidic modules configured for flowing fluid through membranes and associated methods are generally provided. In some embodiments, a fluidic module comprises two channels between which a membrane is positioned. The two channels may have geometries such that the pressure drop experienced by a fluid flowing from the first channel, through the membrane, and into the second channel is substantially independent of the location along the channel at which it flows through the membrane. In other words, the pressure drop may be substantially constant over the membrane area.

  • Patent number: 11497883
    Abstract: The present disclosure pertains to a system and method for automatically detecting rapid eye movement (REM) sleep and delivering sensory stimulation to prolong REM duration, without disturbing sleep. The sensory stimulation may be auditory or other stimulation. The system and method ensure timely delivery of the stimulation and automatically adjust the amount, intensity, and/or timing of stimulation as necessary. REM sleep is detected based on brain activity, cardiac activity and/or other information. REM sleep may be detected and/or predicted by a trained neural network. The amount, timing, and/or intensity of the sensory stimulation may be determined and/or modulated to enhance REM sleep in a subject based on one or more values of one or more intermediate layers of the neural network and one or more brain activity and/or cardiac activity parameters.

  • Patent number: 9982779
    Abstract: A hydraulic control system provides lubrication fluid to a gearbox via two flow paths in parallel. One of the flow paths includes a passive thermal valve in series with a heat exchanger. When the fluid temperature is elevated, the thermal valve opens such that fluid flows through the heat exchanger for cooling. The thermal valve restricts flow to the heat exchanger when transmission fluid is in a normal operating temperature range, reducing flow demands. When the flow demands are reduced, a variable displacement pump requires less torque improving fuel economy. The thermal valve may also open when the fluid is below the normal operating temperature such that the heat exchanger heats the fluid. The parallel path may include a regulator valve. When the pressure of fluid in the lubrication circuit is elevated, the regulator valve reduces flow through the parallel path and may also divert flow to a sump.
