A current sensor comprises a first component comprising plural coils. Each coil comprises one or more turns printed on at least one planar surface of a respective substrate, and the planes of the coils are parallel to one another and are perpendicular to a longitudinal axis of the first component. A second component comprises soft magnetic material and has first and second planar faces that are at opposite ends of the first component and are arranged perpendicularly to and are intersected by the longitudinal axis of the first component.

Sensors

A sensor for use in detecting a time-varying current in a conductor () comprises plural sets of two oppositely-configured sensor elements (--) arranged around a sensing volume having a central axis, the sensor elements (-A,-B) of each set being provided substantially in a common plane that does not intersect the central axis, and each set having a different common plane, the sensor elements of each set being arranged such that a normal (N) of their common plane at a point between central parts of sensor elements lies on a plane (P) that is radial to the central axis of the sensing volume.

Current sensor

A current sensor arrangement comprises plural sensor elements arranged around a center point, each of the sensor elements having a plane of zero sensitivity to uniform magnetic fields. A first one () of the sensor elements has a first angular separation (X) relative to the center point from a second, adjacent sensor element () and a second angular separation (X) relative to the center point from a third, adjacent sensor element (). The first angular separation is less than the second angular separation. An intercept (I) of the planes of the first and third sensor elements is located outside a triangle formed by the center point and the first and third sensor elements and an intercept (I) of the planes of the first and second sensor elements is located inside a triangle formed by the center point and the first and second sensor elements.

Current sensor arrangement

According to an embodiment of the invention, there is disclosed a method of operating a wireless mesh network. The method comprises: seeding the network from a first node; allocating a network address to each member node of the network to form a tree-like structure of the nodes, such that the network address is reversibly derived from the network address of the member node from which it is derived in the tree-like structure; and mapping out cross-branch network connections between nodes that are determined not to be immediate neighbour nodes according to the addresses of the tree-like structure. Further related system embodiments are also disclosed.
