Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A valve mechanism is used in combination with a fluid treatment device of the type having a tank defining a treatment bed, particulate treatment material contained within the treatment bed, and a central distribution tube mounted in the bed and terminating in a plurality of distributors which provide fluid communication between the bed and the distribution tube. The valve mechanism consists of a plurality of ball valves, each connected to a different one of the distributors and having unidirectional flow restriction assemblies such that fluid flow in a first direction from the bed to the distributor tube is relatively unrestricted, and fluid flow in a second direction from the distribution tube to the treatment bed is relatively restricted.

Abstract: A mixed bed deionizer unit which provides in situ regeneration through the use of two compact multi-valve assemblies and an intermediate manifold which are automatically controlled to supply backwash water, chemical draw for cleansing both cation and anion resins simultaneously and rinsing water in a sequentially controlled manner. An internal water and chemical distribution system in the mixed bed tank is provided which has both input distribution and output drainage capabilities.
