Abstract: Described herein is a composition for producing a thiol-ene covalent adaptable network (CAN) polymer. The composition includes a first monomer including at least one thiol group; and a second monomer including at least one anhydride functional group and at least one alkene functional group. Also described herein are a polymer produced from the composition, a method of producing the polymer using the composition, a method of fabricating a polymer article using the composition, as well as a method of degrading the polymer.

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 system for generating fire-fighting foam whereby a foam-forming chemical is mixed with water and air to form foam. The foam is pressurized preferably by the provision of pressurized air to force the foam out of a duct within which the foam is formed and to direct the foam at the seat of the fire or to the site to be protected against fire. A metal mesh is rotatable and preferably helical with respect to the direction of travel of the foam which acts as a catalytic agent and helps to clear foam from the duct within which the foam forms.

Abstract: A plastic band is secured around the outside of a prosthetic heart valve adjacent the sewing cushion to protect the valve leaflet material against inadvertent needle punctures and tears while sutures are being placed through the sewing cushion. The band is held in place by a single retention suture which passes through the band and sewing cushion of the valve and extends across the valve orifice. The protector is especially desirable for use with pericardial tissue valves having the tissue mounted on the outside of the valve stent where the tissue is particularly exposed and susceptible to needle damage.
