Abstract: Described is a task for an automobile interior having at least one subject that creates a video input, an audio input, and a context descriptor input. The video input relates to the at least one subject and is processed by a face detection module and a facial point registration module to produce a first output. The first output is further processed by at least one of: a facial point tracking module, a head orientation tracking module, a body tracking module, a social gaze tracking module, and an action unit intensity tracking module. The audio input relating to the at least one subject is processed by a valence and arousal affect states tracking module to produce a second output and to produce a valence and arousal scores output. A temporal behavior primitives buffer produce a temporal behavior output. Based on the foregoing, a mental state prediction module predicts the mental state of at least one subject in the automobile interior.

Abstract: Concealed fire detector suspension apparatus has a fixing collar and a plurality of radial locking tabs insertable therethrough. A removeable fixing foot is configured for engaging a stem of an upright support for a fire detector and having a peripheral outward locking formations which mechanically interlock with corresponding inward locking formations on an inner surface of the fixing collar. In use, the apparatus is configured for installing the fixing collar via a ceiling cutout, inserting the radial locking tabs through the fixing collar from the interior thereof to clamp the ceiling, inserting the upright support through the fixing collar and locking the outward locking formations of the fixing foot to the corresponding inward locking formations of the cylindrical body, thereby supporting the upright support through the ceiling.
