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 household item (12), such as a microwave oven, can be moved from a lowered storage position to a raised usable position. In the storage position the moving surface lid (14) is flat with the surrounding work surface (10) having been lowered by a manual force and held in place by a suitable catch or latching mechanism. The household item can be raised by pushing the housing slightly downwards, thus releasing the housing from its anchored position. A counterweight (15) greater than the weight of the household item is suspended by way of a wire and pulley system (1a, 1b, 1c) that in turn powers the platform and displaces the lid, on which the household item is located, upwardly.

Abstract: An anti-asphyxia valve includes at least one flap having a first portion adapted for mounting to the housing and a second portion adapted to flex between a first open position allowing gas to pass from the patient side to the housing interior through the at least one port, and from the blower side through the at least one port, to atmosphere when a difference in gas pressure in the housing interior and atmosphere is below a predetermined operating threshold, and a second forcibly closed position substantially occluding the at least one port when the difference in gas pressure between the housing interior and atmosphere is substantially equal to or above the operating threshold.

Abstract: An anti-asphyxia valve is adapted to, in use, be disposed between a patient and structure to deliver a breathable gas to the patient. The valve includes a housing having an interior, at least one port to provide fluid communication between the housing interior and atmosphere and at least one flap including a first portion and a second portion. The first portion is adapted for mounting to the housing. The second portion is adapted to flex between a first biased open position allowing gas to pass from the housing interior through the at least one port to atmosphere when a difference in gas pressure in the housing interior and atmosphere is below a predetermined operating threshold and a second forced closed position substantially occluding the at least one port when the difference in gas pressure between the housing interior and atmosphere is substantially equal to or above the operating threshold.

Abstract: A dilatation catheter includes an inflation balloon having a variable diameter inflation profile. The balloon has a first inflation profile, in which it exhibits a substantially cylindrical central working profile. The first inflation profile of the balloon is achieved by inflating the balloon to a first inflation pressure. The balloon has a second inflation profile which is achieved by increasing the inflation pressure to a second, higher pressure. In the second inflation profile, a proximal segment and a distal segment of the balloon have a first inflated diameter and a central focal segment, separating the proximal and distal segments, has a second inflated diameter, such that the second inflated diameter is greater than the first inflated diameter. Methods of using the catheter are also disclosed.
