    Abstract: Methods and systems provide for detecting tampering of a fuel dispenser. Power is applied to a valve coil of a fuel dispenser. The valve coil is part of a control valve configured to accomplish a gradated fuel flow of the fuel dispenser. Current flowing through the valve coil is measured in response to the power being applied to the valve coil. The current measurements are compared with predetermined criteria and tampering with the valve coil is determined if the current measurements are sufficiently different than expected.

    Abstract: A resonator device 10 is disclosed. The resonator device may be used in a transducer or a sensor such as a pressure, force or acceleration sensor. The resonator device comprises a resonator 20 provided on a diaphragm 30. A cap 40 is provided which may be fusion bonded to the diaphragm 30 to enclose the resonator 20 and form a hermetically sealed package 10. The resonator device is excited by applying electromagnetic stimulation, such as infra-red or optical stimulation, which may be from a laser via a fibre 50. The resonator device may be interrogated by applying an electromagnetic signal into the optical cavity formed between the resonator 20 and the inside surface of the cap 40 to derive a frequency change of the resonator. As the resonator device incorporates a hermetically sealed package and is stimulated by electromagnetic radiation, it is robust and able to operate in harsh environments.

    Abstract: A force sensor includes a pedestal member, an action member, a displacement detecting unit, a ridged member, at least three columnar elastic members, and elastic units. The action member is configured to be displaced by an exerted external force, and the displacement detecting unit detects a displacement of the action member. The rigid member is arranged so as to face the pedestal member. The columnar elastic members extend in a direction perpendicular to the pedestal member, are arranged about an axis at intervals, and connect the pedestal member and the rigid member. The elastic units are arranged about the axis at intervals and connect the action member and the rigid member. The elastic units each include a pair of beam-shaped elastic members extending in a direction parallel to a plane of the pedestal member.
