Abstract: An avionics unit assembly for an aircraft can include an avionics unit (e.g., an underwater locator device, “ULD”), and a battery to power the avionics unit. The avionics unit assembly can further include a housing that encases the avionics unit and the battery. The housing includes a vent port for exhausting an emission from the housing during a failure of the avionics unit. The avionics unit assembly can further include one or more of a suppressor that filters the emission, a shield element that is resistant to chemical and/or thermal effects of the emission, and a bracket for mounting the avionics unit to a surface. A method integrating the avionics unit assembly onto a forward aircraft bulkhead at a mount location under an aircraft radome and for manufacturing the avionics unit, and an aircraft including the avionics unit are also described.

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: An optical mount includes a mount material in a closed geometry with an outer surface sized for matching internal dimensions of an outer housing, and an inner surface including spaced apart inward extending contacting features providing contact points that collectively define an inner opening sized for securing an optical device including a crystal within. At least one feature gap or a recessed portion is between the inward extending contacting features. Edge holders are adapted for receiving corners of the optical device can be the protrusion pair or inner notches. The outer surface includes at least one outer notch between the inward extending contacting features. The edge holders and outer notch(es) are for each acting as hinge points opening or pinching depending on a direction of force on the optical mount for responding with flexure when there is a dimensional change in the crystal, mount material, or the housing.

Abstract: As one non-limiting example, a foldable mast assembly for a sailing vessel is provided. The foldable mast assembly includes a lower mast section; an intermediate mast section having a lower end foldably coupled to an upper end of the lower mast section; an upper mast section having a lower end foldably coupled to an upper end of the intermediate mast section; and a boom coupled to the lower mast section. A locking device internal the mast assembly is also provided to inhibit folding of the mast assembly.
