Abstract: A method of transferring ownership of item(s) includes securely identifying the item(s) by attaching a security tag to the item(s). The security tag has a monitoring system for monitoring a tag status, the tag status indicating whether the security tag and/or the item(s) have been tampered with. The method includes detecting remotely a condition of the monitoring system and causing a remote host to register a change in ownership of the item(s) when the monitoring system does not indicate a tampered condition.

Abstract: A security tag for securely identifying items comprises a housing (1); a securing mechanism (6) for securing the housing to the item; a monitoring system (20, 24) for monitoring a tag status, the tag status indicating at least whether the housing (1) and the securing mechanism (6) have been tampered with; a store (22) for storing item data identifying the item; and a communication system (21) for communicating tag status and item data to a remote host.

Abstract: A video camera or equivalent sensor is mounted on a vehicle and used to detect the lane markings on the road (usually the white painted lines). An associated signal processor (11) estimates the vehicle's lateral position in relation to the lane markings. An electric motor (4) coupled to the steering mechanism (1) is used to provide a torque input to the steering which may either assist or oppose the steering torque from the driver. The processor (11) is designed to assist the driver to maintain the vehicle's lane position by holding the vehicle at a set-point using a biasing torque. This simulates the effect of the lane being cambered upwards towards the lane edges. However the driver is able to override or cancel the effect if the driver applied steering torque exceeds a prescribed torque threshold.
