A gradient amplifier system is presented. As a result, the thickness of latch measured in the direction of its rotational axis is slightly larger than the thickness in the shaft region, particularly at a location in the area of transition from the latch shaft to the latch spoon. In response to the command, the system overlays a semi-transparent layer over at least a portion of a display which is generated by the application, so that the data within the display is still visible to the user. The invention results in a beneficial trade-off in which bandwidth for the multi-port bridge and latency are both increased.
