A system and related techniques to collect and manage a set of incoming message notification objects, such as instant message notifications, email notifications, download notifications, transaction notifications and others and present those objects to the user an icon, tile or other representation on a dynamically scaled timeline. According to embodiments, the dynamically scaled timeline may present the most recently received object farthest to the right on a notifications bar or facility, and slide objects to the left to represent that passage of time as those objects age. Instead of presenting those objects on a linear scale, according to the invention the time intervals in which the objects may be presented may be scaled to cause the oldest message objects to be presented on a relatively compressed dimension. The most recently received messages in contrast may be presented on wider intervals, to permit the user to perceive the differences in arrival of those items more clearly. According to embodiments, when more than one message object slides to an overlapping point with another, those objects may be stacked into a cascading message stack. When two or more stacks touch, they may be merged into a single stack. According to embodiments of the invention in another regard, when the user hovers over a given message object a popup box may appear which displays attributes of that object, such as message or other notification type, the date and time which the object was received, the source of the underlying message or other data. In further embodiments, one or more of the message notification objects may be clickable or otherwise reactivatable to reveal actions, dialogs, inputs or other interactions which were presented at the time the message was originally received, such as a query box to input a password or a selection for an email address.

An absolute pressure sensor includes a sense die with a reference chamber on a top side thereof. The reference chamber comprises a precisely fabricated beam that limits the travel of a diaphragm. The beam can be positioned in a cap or cover member of the sense die, thereby allowing the sense die diaphragm to move freely for a particular distance. Over this distance, the sense die will have one sensitivity. When the sense die is pressurized to a certain point, the diaphragm moves until it contacts the beam member in the cap or cover. When the diaphragm hits the beam, the sensitivity of the sense die changes, thereby allowing a smaller voltage out for the greater pressure in. Such an arrangement permits the sensor to provide a function that accurately measures low pressure and measures a higher pressure without utilizing a linear scale.
