Abstract: Systems and methods for automatically assessing and monitoring information security effectiveness using collected indicia of sensitive content and indicia of security measure information for a plurality of networked organizational assets/systems to provide respective asset/system value at risk ratings. Elements of the system include automated asset discovery, automated hosting provider and location discovery, collection of information harvested from public sources and, optionally non-public sources, analysis of the collected information against public, non-public, and proprietary sources, and/or mathematical models used to infer broader security program conclusions and to rank asset/system values at risk. Estimates of values at risk are used to prioritize allocation of security measures.

Abstract: The present invention provides a position sensor which is suitable for use in a piston and cylinder assembly. The position sensor includes a movable field modifying member which is operable to vary the inductance of a sensor winding, whereby the position of the field modifying member relative to the sensor winding can be determined by monitoring the inductance of the sensor winding. The position sensor also includes a compensation winding which is arranged to have a common coupling with the field modifying member whereby a signal output from the compensation winding can be used to compensate for variations in the signal level output by the sensor winding caused by, for example, temperature variations of the system.

Abstract: A linear position sensor is provided which employs phase quadrature sensor windings, an excitation winding and a resonator. When an excitation current is applied to the excitation winding, it causes the resonator to resonate which in turn induces signals in the sensor windings. The sensor windings are spatially arranged so that the electromagnetic coupling between them and the resonator varies with the position of the resonator. The excitation windings, phase quadrature windings and resonant circuit are arranged so that the magnetic fields involved in the operation of the position sensor are substantially parallel to each other and the direction of movement of the resonator. Consequently, the effect of rotation of the resonator or lateral movement of it relative to the excitation and phase quadrature windings is alleviated.
