Abstract

A modular fluid-dispensing system includes a master control dispenser and/or one or more satellite dispensers that communicate bi-directionally with the master control dispenser. The master control dispenser is programmable and may dispense one or more solutions. Each satellite may dispense fluid in either a stand-alone mode or under control of another fluid-dispensing-system component, such as a master control dispenser, or a grinder/polisher. A master control dispenser may store various multi-step dispensing methods and may advance a dispensing method to a next step automatically or based on a control signal received from a grinder/polisher. A master control dispenser may perform a fluid-dispensing method that is synchronized with a corresponding grinder/polisher method performed by a grinder/polisher that is coupled to the master control dispenser.

Claims

wherein the first satellite dispenser receives a query from a master control dispenser based on the master control dispenser automatically detecting that the first satellite dispenser has transitioned from being uncoupled from the master control dispenser to being coupled to the master control dispenser, and wherein the first satellite dispenser sends to the master control dispenser a response to the query thereby confirming that the first satellite dispenser has transitioned from being uncoupled from the master control dispenser to being coupled to the master control dispenser; and

wherein the first satellite dispenser can operate in both a stand-alone mode of operation and under control of the separate fluid-dispensing-system component.

2. The fluid-dispensing system of claim 1, further comprising:

an external power supply that supplies electrical power to the first satellite dispenser.

8. The fluid-dispensing system of claim 1, further comprising:

a second satellite dispenser having a second coupling port; and

a coupling that couples the first satellite dispenser to the second satellite dispenser through the first and second coupling ports.

9. The fluid-dispensing system of claim 8, wherein the first satellite dispenser provides, through the coupling, a signal selected from the group consisting of:

electrical power from a power supply, a fluid-dispensing cycle-start signal, and a fluid-dispensing cycle stop signal.

10. The fluid-dispensing system of claim 9, wherein the fluid-dispensing cycle-start signal causes the second satellite dispenser to start a second fluid-dispensing cycle at a second-fluid-dispensing-cycle-start time that is substantially the same as a first-fluid-dispensing-cycle-start time when the first satellite dispenser starts a first fluid-dispensing cycle.

11. The fluid-dispensing system of claim 10, wherein the first fluid-dispensing cycle and the second fluid-dispensing cycle can be programmed to end at different times.

12. The fluid-dispensing system of claim 10, wherein the first fluid-dispensing cycle and the second fluid-dispensing cycle can be programmed to dispense different amounts of fluid.

13. The fluid-dispensing system of claim 1, further comprising a grinder/polisher coupled to the first satellite dispenser by a grinder/polisher-to-satellite coupling.

14. The fluid-dispensing system of claim 13, wherein the grinder/polisher provides to the first satellite dispenser, through the grinder/polisher-to-satellite coupling, a signal selected from the group consisting of:

electrical power from a power supply, a fluid-dispensing cycle-start-signal, and a fluid-dispensing cycle-stop signal.

15. The fluid-dispensing system of claim 14, wherein the first satellite dispenser provides to a second satellite dispenser, through a satellite-to-satellite coupling, at east one of the signals recited in claim 14.

16. The fluid-dispensing system of claim 15, wherein the fluid-dispensing cycle-start signal causes the second satellite dispenser to start a second fluid-dispensing cycle at a second-fluid-dispensing-cycle-start time that is substantially the same as a first-fluid-dispensing-cycle-start time when the first satellite dispenser starts a first fluid-dispensing cycle.

17. The fluid-dispensing system of claim 15, wherein the first fluid-dispensing cycle and the second fluid-dispensing cycle can be programmed to end at different times.

18. The fluid-dispensing system of claim 15, wherein the first fluid-dispensing cycle and the second fluid-dispensing cycle can be programmed to dispense different amounts of fluid.

19. A fluid-dispensing method executed in a first fluid dispenser that can be configured to operate in a stand-alone mode and that can be configured to operate under control of a separate fluid-dispensing system component, the method comprising:

when the first fluid dispenser is configured to operate in a stand-alone mode,

configuring the first fluid dispenser based on at least one configuration parameter input through the first fluid dispenser'"'"'s user interface, and
