Abstract: The present invention is a system and method for a UAV flight highway and management thereof, comprising: a ground control station, a server (for example a cloud server), a geographic locator communication device, a communication transmitter, and one or more UAVs. The present invention is operable to identify ground level topography and air space objects (e.g., buildings) within a region, as well as other restrictions to UAV flights (e.g., restricted flight zones), and generates within such region a UAV flight highway, that may be multi-lane and multi-layer, based upon specific latitudinal and longitudinal points. The present invention is operable to control the flight of one or more UAVs along such flight highway, along multiple-lanes thereof, wherein the UAVs may travel at different speeds in different lanes and different layers along the UAV flight highway.

Abstract: An actuator arrangement for an electromagnetically operated fuel injector includes a pole member having a first end face and defining an aperture extending from the first end face and an actuator core received within the aperture. The actuator core carries at least one contact member having a contact face that is exposed through the aperture. An encapsulating member is received within the aperture and surrounds the at least one contact member. The first end face of the pole member, the contact face and the encapsulating member are arranged to provide the actuator arrangement with a substantially planar surface for mating with an adjacent component, in use.

Abstract: An actuator arrangement for an electromagnetically operated fuel injector includes a generally cylindrical actuator core having a longitudinal axis and defining an inner pole face of the actuator arrangement. The actuator core is formed of a bespoke magnetic material. A wire coil is disposed around the actuator core arranged to be connected to a power source to generate a magnetic field around the coil. A pole member is formed of a high strength material and defines an aperture for receiving the actuator core. The pole member defines an outer pole face of the actuator arrangement substantially co-planar with the inner pole face. An armature is movable in a direction parallel to the longitudinal axis in response to the magnetic field. The magnetic field passes into the armature in the region of the inner pole face and into the armature in the region of the outer pole face.
