Abstract: A method is provided for predicting occurrence of a temperature rise event caused by a fire within an environment. The method comprises receiving temperature data captured by at least one temperature sensor 6, 8 for sensing an ambient temperature in the environment, processing the temperature data captured by the at least one temperature sensor in a previous window of time using a trained machine learning model 16 to determine a risk indication indicating risk of the temperature rise event occurring in a future window of time, and outputting a warning indication in dependence on the risk indication determined using the machine learning model. This is useful for providing firefighters with advance warning of dangerous temperature rises such as flashover events.

Abstract: Techniques are disclosed relating to authorizing varying levels of access to computer resources. In one embodiment, consider an authorization server, a resource server that includes a resource (for example, a data item), and an application server operable to incorporate the resource into its own functionality. The authorization server may receive information indicative of a grant of access privileges by a user, authorizing the application server to access the resource. The authorization server may be configured to provide the application server with varying levels of access to the resources of the resource server. For example, the authorization server may provision a plurality of access tokens corresponding to the grant of access privileges to the application server. The plurality of access tokens may each be associated with a scope of access and a duration. In various embodiments, the duration of an access token may be based on its corresponding scope of access.
