Abstract: Systems and methods for managing task-driven field-based workers are described. In an embodiment, a distributed system comprises a component running on a mobile device which displays an activity-based workflow to a user. At transition points in the workflow, one or more activity transactions are transmitted from the mobile device to an Activity Processing Engine. A transaction may comprise: a start time, a start location, an end time, an end location and an activity code, although for a ‘start activity’ transaction, the fields relating to the end of the activity will be null/absent. The Activity Processing Engine analyses the data to generate task-based milestones and behavioural scores for the field-based worker, which may be aggregated over multiple shifts. The detailed information about the activities on shift and the behavioural scores are presented in a graphical user interface which provides objective data about how a worker goes about completing their tasks.

Abstract: A release mechanism is located within a vehicle trunk for releasing the trunk lid. The mechanism includes a handle coated with a phosphorescent material to allow the handle to be viewed within a darkened trunk. The phosphorescent material is excited or made to glow by external light conducted through light-conducting means. The light-conducting means extends between a location external to the vehicle and a point adjacent the handle. The handle glows for a period of time following the exposure to the external light entering the conducting means to allow visibility of the handle within a darkened trunk.
