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 chimney cleaner of universal application and especially suitable for cleaning heavy wood resin residue is disclosed. An A-frame assembly capable of expansion and contraction to accommodate various chimney sizes is held together by pivot connections. The manual reciprocation of the cleaner by a user through a rod which forms the cross bar of the A-frame produces a longitudinal reciprocation of the A-frame. A right angled brush may be removably mounted on the A-frame along its top and fits into a chimney outwardly from a corner. The legs of the A-frame end in wheels which ride up and down the chimney corner opposite the brush. The chimney cleaner's overall dimensions may be increased or decreased by applying a torque to the rod which, through a threaded connection with a leg, will cause the legs to spread or contract.
