Patent number: 11963047Abstract: 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).Type: GrantFiled: October 18, 2018Date of Patent: April 16, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Athanasios Karapantelakis, Elena Fersman, Rafia Inam, Markus Andersson, David Lindero

Patent number: 11106312Abstract: 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.Type: GrantFiled: March 6, 2019Date of Patent: August 31, 2021Assignee: FlatFrog Laboratories ABInventors: Tomas Christiansson, Orjan Friberg, David Andersson
