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 strut assembly includes an axially elastically extensible tube having attachment means at each end and an axially extensible actuator attached within the tube and between its ends so that reciprocal axial extensions of the actuator cause elastic longitudinal displacements of the strut assembly. Such a strut assembly is particularly useful for transmitting operational loads between parts of a structure and for inputting periodic loads into one of the parts as part of an active vibration control system.

Abstract: A method for detecting a crack in the main load bearing spar of a hilicopter rotor blade consists of attaching a capillary tube along an external surface of the spar and connecting the interior of the tube to a supply of colored liquid contained in a reservoir at a root end of the blade, whereby a crack in the spar causes a corresponding crack in the capillary tube resulting in visible leakage of the colored liquid.
