    摘要： There is disclosed an inductive power transfer system including a primary unit and a secondary device separable from the primary unit, the primary unit may include a power transfer surface and more than two field generators each operable to generate an electromagnetic field. The field generators may be located at different positions relative to the power transfer surface. The secondary device may include a power receiver having a secondary coil. In one embodiment, the system may determine at least one of the position and the orientation of the power receiver relative to the power transfer surface, and control the field generators such that at least one first field generator and at least one second field generators, selected in dependence upon such determination, are active in a substantially opposite sense to one another so as to direct magnetic flux through the secondary coil thereby supplying power to the secondary device, and further such that a third one of the field generators is inactive so that fewer than all of the field generators are active simultaneously.

    摘要： A flow measurement device 100 is provided that includes an electrode terminal chamber 102 with an inlet 104 in communication with a flow channel 108 for receiving fluid and viscoelastic material aspirated from a surgical site, and an outlet 106 that tapers into a flow channel 108. The outlet 108 has a taper angle that is sufficient to smooth flow and cause viscoelastic material entering the electrode terminal chamber 102 to flow substantially within a center portion of the chamber and through the outlet 106. The electrode terminal chamber 102 further includes first and second electrode terminals 130 and 140 disposed on generally opposite sides of the electrode terminal chamber 102 in a spaced-apart manner. The first and second electrode terminals 130 and 140 are positioned a distance from the center of the chamber 102 that is sufficient to substantially avoid contact between the terminals and viscoelastic materials flowing through the chamber 102.
