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 barge cover is wound on a roller, mounted on a trolley which may be moved from one end to the other end of a barge hold, deploying or taking up the cover as it moves. The cover may then be sealed around the barge coaming in a weather proof manner. The roller is mounted on trolleys so that two men may deploy or take up the cover with only their muscle power, without requiring either special docking facilities or an independent power source.
