  • Patent number: 11878717
    Abstract: In an approach to mirage detection by autonomous vehicles, one or more computer processors monitor road conditions of a road on which an autonomous vehicle is traveling. One or more computer processors detect a visual indication of a water accumulation on the road. One or more computer processors determine whether one or more other vehicles are detected on the road ahead of the autonomous vehicle. Responsive to determining the one or more other vehicles are detected, one or more computer processors request information associated with road conditions of the road ahead of the autonomous vehicle from the one or more other vehicles. Based on a response to the request from the one or more other vehicles, one or more computer processors determine the one or more other vehicles did not detect the water accumulation. One or more computer processors determine the visual indication of the water accumulation is a mirage.

  • Patent number: 11733354
    Abstract: A LIDAR sensor assembly includes a laser light source to emit laser light, and a light sensor to produce a light signal in response to sensing reflections of the laser light emitted by the laser light source from a reference surface that is fixed in relation to the LIDAR sensor assembly. A controller of the LIDAR sensor assembly can process a plurality of samples of reflected light signals, process the samples to remove erroneous readings, and then provide accurate distance measurement. The system can use low-pass filters, or other components, to filter the plurality of samples to enable the “actual,” or primary, reflected light signal (i.e., light signal reflected off of a surface in an environment external to the sensor assembly, as opposed to extraneous, internal reflections off of lenses or other components or noise) to be identified and an accurate time of flight to be calculated.

  • Patent number: 11681029
    Abstract: A time delay of arrival (TDOA) between a time that a light pulse was emitted to a time that a pulse reflected off an object was received at a light sensor may be determined for saturated signals by using an edge of the saturated signal, rather than a peak of the signal, for the TDOA calculation. The edge of the saturated signal may be accurately estimated by fitting a first polynomial curve to data points of the saturated signal, defining an intermediate magnitude threshold based on the polynomial curve, fitting a second polynomial curve to data points near an intersection of the first polynomial curve and the intermediate threshold, and identifying an intersection of the second polynomial curve and the intermediate threshold as the rising edge of the saturated signal.

  • Publication number: 20220355250
    Abstract: Systems and methods for separating a liquid mixture are disclosed. A membrane is first soaked by the liquid mixture via dynamic soaking to reach steady state. During the soaking process, the flow rate of the liquid mixture is increased at a flow rate ramp, the temperature is increased at a temperature ramp, and the pressure drop is increased at a pressure drop ramp. After the soaking process, the liquid mixture is separated by the membrane under optimized conditions to produce a permeate and a retentate.

  • Patent number: 11470515
    Abstract: A mechanism is provided to ensure the same user plane anchor point is selected as a User Equipment (UE) moves across multiple access networks. The selected User Plane Function (UPF) identifier information, such as a Fully Qualified Domain Name (FQDN) is passed to the UE anchor points. This will allow the UE anchor points to exchange the already selected user plane information so that the new UE anchor point can choose the same UPF.

  • Patent number: 11425262
    Abstract: A network element configured to support charging for a service in a network accesses policy rules defining a rating group to be used for offline charging. While a protocol data unit (PDU) session for user equipment is being established in the network, the network element sends, to a charging function configured to send charging data records related to service usage to a billing domain, a charging data request that establishes offline charging for the PDU session and indicates the rating group. The network element also receives, from the charging function, a charging data response including one or more triggers and thresholds for the rating group for the offline charging.
