Abstract: A computer-implemented method of predicting an external actor trajectory comprises receiving, at a computer, sensor inputs for detecting and tracking an external actor; applying object tracking to the sensor inputs, in order track the external actor, and thereby determine an observed trace of the external actor over a time interval; determining a set of available goals for the external actor; for each of the available goals, determining an expected trajectory model; and comparing the observed trace of the external actor with the expected trajectory model for each of the available goals, to determine a likelihood of that goal.

Abstract: One aspect herein provides a method of analysing driving behaviour in a data processing computer system, the method comprising: receiving at the data processing computer system driving behaviour data to be analysed, wherein the driving behaviour data records vehicle movements within a monitored driving area; analysing the driving behaviour data to determine a normal driving behaviour model for the monitored driving area; using object tracking to determine driving trajectories of vehicles driving in the monitored driving area; comparing the driving trajectories with the normal driving behaviour model to identify at least one abnormal driving trajectory; and extracting a portion of the driving behaviour data corresponding to a time interval associated with the abnormal driving trajectory.

Abstract: An intravenous catheter securement device includes a holder for placement on a bodily appendage near an intravenous insertion site on the bodily appendage, a strap for securing the holder to the bodily appendage, and at least one securement feature formed on the holder and configured to secure at least a portion of an intravenous catheter. The holder is shaped to surround at least a portion of the bodily appendage. The at least one securement feature is a slot formed on the holder. The holder includes a tray having an interior cavity and a tearable lid covering the interior cavity.

Abstract: An autonomous vehicle (AV) planning method comprises: receiving sensor inputs pertaining to an AV; processing the AV sensor inputs to determine an encountered driving scenario; in an AV planner, executing a tree search algorithm to determine a sequence of AV manoeuvres corresponding to a path through a constructed game tree; and generating AV control signals for executing the determined sequence of AV manoeuvres; wherein the game tree has a plurality of nodes representing anticipated states of the encountered driving scenario, and the anticipated driving scenario state of each child node is determined by updating the driving scenario state of its parent node based on (i) a candidate AV manoeuvre and (ii) an anticipated behaviour of at least one external agent in the encountered driving scenario.

Abstract: Abstract: A driving scenario is extracted from real-world driving data captured within a road layout. A simulation is run based on the extracted driving scenario, in which an ego agent and a simulated non-ego agent each exhibit closed-loop behaviour. The closed-loop behaviour of the ego agent is determined by autonomous decisions taken in an AV stack under testing in response to simulated inputs, reactive to the simulated agent. The closed-loop behaviour of the non-ego agent is determined by implementing an inferred goal or behaviour, reactive to the ego agent. The goal or behaviour is inferred from an observed trace of a real-world agent extracted from the real-world driving data.

Abstract: Ego actions for a mobile robot in the presence of at least one agent are autonomously planned. In a sampling phase, a goal for an agent is sampled from a set of available goals based on a probabilistic goal distribution, as determined using an observed trajectory of the agent. An agent trajectory is sampled, from a set of possible trajectories associated with the sampled goal, based on a probabilistic trajectory distribution, each trajectory of the set of possible trajectories reaching a location of the associated goal. In a simulation phase, an ego action is selected from a set of available ego actions and based on the selected ego action, the sampled agent trajectory, and a current state of the mobile robot, (i) behaviour of the mobile robot, and (ii) simultaneous behaviour of the agent are simulated, in order to assess the viability of the selected ego action.
