Abstract: A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing, the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.

Abstract: A variable rate controlled delivery drive mechanism includes a drive mechanism housing, at least partially within which initially resides a biasing member positioned in an initially energized state within an inner cavity of a piston. The drive mechanism may include a gear drive having one or more screws and one or more corresponding nuts. The piston contacts a plunger seal and is configured to axially translate the plunger seal, by force asserted upon it from the biasing member, from a first position to a second position within a drug container for drug delivery. The biasing member is metered from free expansion from its energized state by the gear drive and a gear assembly mechanism having a motor. A drug delivery pump utilizes such variable rate controlled delivery mechanisms. A status reader configured to recognize one or more corresponding status triggers is utilized to provide feedback to a user.

Abstract: Systems, methods, and computer program products are provided for a financial health indicator. The financial health indicator provides a dynamic indication of a user's financial health in terms of their current credit and their current ability to save in relation to a budget. The systems, methods, and computer program products also provide for user-configured spending guardrails in a budget tracking system. The use of spending guardrails is instrumental in insuring that the user of the budget tracking system adheres to their assigned budget. By providing for dynamically configurable spending thresholds the user may define, change, suspend, or the like spending guardrails as dictated by current circumstances. The configurable nature of the guardrails insures that guardrails are tailored to the needs of the individual user.
