Abstract: A method and system for community-based social connectivity. In one implementation, the method can include establishing a group from a plurality of members of a predetermined organization, and storing in memory personal information about the members. In some embodiments, the method can include adding members to the group, and associating at least some members with at least one subgroup at least partially based on the personal information. The method can provide associating the members with a personal communication board and a community communication board and receiving communications from one or more members. The method can include displaying communications created by the members on the personal communication and community communication boards.

Abstract: The present invention provides systems and methods of dispensing liquids. In one embodiment, the system includes a pump with a removable pump module with at least one displacement piston and at least one piston valve. A motor and base assembly provide the supporting components of the pump which can be used in environments where precise small volumes of ultra-pure liquids must be transferred from a reservoir to a point of use. The preferred embodiment of the system prevents contaminants and air bubbles from being introduced into the liquid to be dispensed by placing a filter across the discharge line downstream from the pump, and providing a separate drawback line for performing the drawback of the liquid in the dispensing nozzle.
