Claim:
1. A system for on-body fluid delivery comprising: a primary user interface device comprising a display and a primary user interface real-time clock; a primary patch pump comprising a pump mechanism and a primary patch pump real time clock, the primary patch pump adapted to attach a first infusion cannula to a user, the primary patch pump further adapted to perform a plurality of primary patch pump functions; and a secondary patch pump comprising a secondary patch pump real time clock, the secondary patch pump adapted to attach a second infusion cannula to a user, the secondary patch pump further adapted to perform a plurality of secondary patch pump functions substantially similar to the plurality of primary patch pump functions if an error condition associated with the primary patch pump is determined; wherein the primary user interface device, the primary patch pump, and the secondary patch pump are each adapted to enter SLEEP, WAKE, and SNIFF modes in synchronicity with one another based on said real time clocks; wherein less power is consumed by said display of said primary user interface device and said pump mechanism of said primary patch pump during said SLEEP mode than during said WAKE mode, and wherein communication between devices is checked during SNIFF mode; and wherein at least one of a SLEEP cycle, a WAKE cycle and a SNIFF cycle of the primary user interface device is synchronized with at least one of a SLEEP cycle, a WAKE cycle and a SNIFF cycle of a primary patch pump to save energy, using the primary user interface real-time clock and the primary patch pump real-time clock.
