Abstract: A medical delivery system comprising a container and a coupling mechanism movable between a coupling position wherein distal movement of a drive mechanism is transferred to an actuator, and a non-coupling position wherein distal movement is not transferred to the actuator. Moreover the present invention relates to a dosing assembly for use in the medical delivery system and a container for use in the medical delivery system. Finally, the present invention relates to medical delivery system comprising a dosing assembly having means for preventing a drive stem of the dosing assembly from being moved in a distal direction.

Abstract: A switching system and method are provided to facilitate use of videoconference facilities over a plurality of security levels. The system includes a switch coupled to a plurality of codecs and communication networks. Audio/Visual peripheral components are connected to the switch. The switch couples control and data signals between the Audio/Visual peripheral components and one but nor both of the plurality of codecs. The switch additionally couples communication networks of the appropriate security level to each of the codecs. In this manner, a videoconferencing facility is provided for use on both secure and non-secure networks.

Abstract: A transilluminator having a housing having therein a window, a first light source supported within the housing for transmitting light through the window and illuminating a sample adjacent the window, and a second light source which is mounted outside the housing and which is movable between a first position wherein the second light source is removed from the window, and a second position wherein the second light source is over the window for transmitting light onto a sample adjacent the second light source.
