Abstract: One embodiment is a dispensing apparatus including a dispensing head for a fluid, wherein the dispensing head comprises an actuator, a pump mechanism and a locking member. The actuator is movable relative to the pump mechanism from a lock position to a first pump position and moveable relative to the pump mechanism between a first pump position and a second pump position for actuating said pump mechanism. The dispensing apparatus is configurable into a locked configuration, in which the actuator is in the lock position and in which the locking member is braced between the actuator and the pump mechanism to prevent movement of the actuator from the lock position, and an unlocked configuration in which the locking member allows movement of the actuator from the lock position, and wherein the dispensing head is adapted to revert from the unlocked configuration when the actuator is returned to the lock position.

Abstract: A method of varying the content of a physical display at a broadcast event between a direct viewer and a broadcast viewer, wherein the display comprises a direct viewer display image and a broadcast viewer display image, wherein the display displays one or more temporally interleaved data content instances, and wherein the display image for a broadcast viewer is synchronised to show one of said data content instances.
