Abstract: According to an aspect of the present invention, there is provided an electrical connector socket comprising a housing having a front face configured to mate with a corresponding face of a corresponding plug; at least one electrical connector pin mounted on a mounting assembly inside the housing, the mounting assembly being movable in a direction substantially perpendicular to the front face; wherein: the mounting assembly includes a magnetic member configured to interact with a corresponding plug-side magnetic member of the plug to establish a magnetic attraction force, to urge the movable mounting assembly towards the front face to a coupling position in which the at least one connector pin protrudes through a corresponding at least one opening in the front face; the mounting assembly further including a resilient member configured to exert a restoring force on the mounting assembly, to urge the mounting assembly towards a rest position in which the at least one connector pin does not protrude from the

Abstract: Active noise cancellation may be provided by a variety of systems, methods and techniques. General aspects, for example, include an active noise cancellation system, a controller for an active noise cancellation system, and/or a method of generating an anti-noise signal. In one example aspect, an active noise cancellation system for an aircraft In-flight entertainment system may include at least one input device, a processing means, and an output. The input device may be associated with a seat on the aircraft and adapted to receive an input representative of an ambient noise in the vicinity of the seat. The processing means may be adapted to process the input to produce an output signal adapted to reduce the ambient noise in volume associated with the seat. The output may be adapted to transmit an output signal to at least one driver, which is adapted to transmit the output signal to a user.
