  • Patent number: 11963047
    Abstract: Decision-making equipment (22) is configured for link change decision-making using reinforcement learning. The decision-making equipment (22) is configured to track rewards (30-1, . . . 30-M) earned for, and outcomes (28-1, . . . 28-M) of, respective link change decisions (26-1, . . . 26-M). In some embodiments, possible outcomes of a link change decision to change a serving link of a wireless device to a target link include at least: a change of the serving link of the wireless device from the target link to another link; and a network-initiated disconnect of the wireless device from the target link. Regardless, the decision-making equipment (22) is also configured to make a link change decision (28-(M+1)) based on the tracked rewards (30-1, . . . 30-M) and outcomes (28-1, . . . 28-M).

  • Publication number: 20230381539
    Abstract: A method (100) for generating a treatment plan specifying an irradiation of a patient, the method comprising: a dose inference stage (112), including using a model to infer a spatial dose from patient data; a dose mimicking stage (116), including executing a robust optimization process to generate a deliverable treatment plan which is consistent with the inferred spatial dose, wherein the robust optimization considers a plurality of scenarios relating to patient data uncertainty.

  • Publication number: 20220413652
    Abstract: A touch sensing apparatus is disclosed for detecting touch pressure, comprising a panel that defines a touch surface, the panel having a perimeter, a plurality of emitters arranged along the perimeter, wherein the emitters emit light across the panel, a plurality of detectors arranged along the perimeter, whereby the detectors are arranged to receive at least part of said light as detection light, wherein the touch sensing apparatus is configured to determine, as a touch object deflects the panel along a normal of the touch surface, a difference in the received detection light between deflection of the panel from a first position (p1) to a second position (p2) along the normal, and determine a pressure of the touch object against the touch surface based on said difference.

  • Patent number: 11175756
    Abstract: A touch sensing apparatus is disclosed comprising a touch surface, and a touch sensor configured to determine a first set of coordinates on the touch surface of an object in contact with the touch surface. The touch sensing apparatus is configured to determine a virtual brush angle associated with the object, determine a movement of the object to a second set of coordinates determine an updated virtual brush angle for the object in dependence on a position of the second set of coordinates relative to the first set of coordinates, and output the second set of coordinates and the updated virtual brush angle. An associated method is also disclosed.

  • Patent number: 11106312
    Abstract: A method of predicting the behaviour of one or more objects on a touch surface of a touch-sensitive apparatus comprises outputting an object position value of a first time series describing a position of the one or more objects on the touch surface. The method further comprises outputting an object position value of a second time series describing a position of the one or more objects on the touch surface. The object position value of the second time series is outputted before the corresponding object position value of the first time series. The method yet further comprises predicting the behaviour of the one or more objects based at least on the object position values of the second time series.
