  • Network architecture, methods, and devices for a wireless communications network
    Patent number: 11381445
    Abstract: Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

  • Smart waste collection system rerouting collection based on waste container accessibility
    Patent number: 11074556
    Abstract: A waste collection system includes waste containers for receiving waste, sensors associated with the waste containers, a server system for receiving signals from the sensors. The server system determines that a waste container needs to be collected, determines a location of the waste container and whether the waste container is in a waste collection vehicle accessible location. A notification is sent to an operator of the waste container if the waste container is not in a waste collection vehicle accessible location. When the waste container is moved to a waste collection vehicle accessible location, an optimal waste collection strategy for a waste collection vehicle to collect waste from the waste container at the waste collection vehicle accessible location is determined and the waste collection vehicle is routed to the location of the waste container.

  • Systems And Methods For Detecting And Dynamically Mitigating Driver Fatigue
    Publication number: 20210001864
    Abstract: This technology relates to dynamically detecting, managing and mitigating driver fatigue in autonomous systems. For instance, interactions of a driver in a vehicle may be monitored to determine a distance or time when primary tasks associated with operation of the vehicle or secondary tasks issued by the vehicle computing were last performed. If primary tasks or secondary tasks are not performed within given distance thresholds or time limits, then one or more secondary tasks are initiated by the computing device of the vehicle. In another instance, potential driver fatigue, driver distraction or overreliance on an automated driving system is detected based on gaze direction or pattern of a driver. For example, a detected gaze direction or pattern may be compared to an expected gaze direction or pattern given the surrounding environment in a vicinity of the vehicle.

  • Method and arrangement for generating steam at a digester plant of a chemical pulp mill
    Patent number: 10329713
    Abstract: The present invention relates to a method of producing steam at a digester plant of a chemical pulp mill. Black liquor is discharged from the digester at a first temperature and pressure. The black liquor is treated in a flash tank for generating flashed black liquor and flash steam at a second temperature and a second pressure, which are lower than the first temperature and pressure. The flashed black liquor is taken for further treatment to the evaporation plant. The flash steam is led to an indirect heat exchange contact with clean liquid in the reboiler for boiling the liquid and for generating steam. The steam is led from the reboiler into a fan or compressor for increasing the steam pressure to a third pressure, which is higher than the second pressure and for adjusting the pressure of the steam in the flash tank. Steam at a third pressure is used for pretreating comminuted cellulosic fiber material, such as chips, prior to cooking.
