A portable item reporting device (200) is configured to be attached to and in substantial collocation with a portable item (100), or to be integrated into a portable item (100). The device (200) includes environmental sensors (210) to monitor item location, movement, ambient light, sounds, temperature, etc. The device (200) is configured to store usage expectation data (600) indicative of historical and/or expected item usage and environments when the item (100) is in normal use/storage associated with an authorized user (AU). The device (200) monitors current environmental conditions (104) surrounding and pertaining to the item. If the current environment (104) is inconsistent with expected conditions (600), the device (200) assesses that the item (100) is displaced (503.0), meaning either that the item (100) is in abnormal use or abnormal storage, or is under the control of an unauthorized user (UU) who is other than the authorized user (AU). Based on the assessment the device initiates a signal (372) or message (374) to an authorized user (AU) of the item (100), indicating that the item (100) usage/storage is displaced (503.0) or otherwise anomalous (503.2). |
