Abstract: A speech valve for placing and fitting on a tracheostomy cannula, having a throughflow body enclosing a throughflow channel which on one side at one end has a connection for joining to a proximal end of the tracheostomy cannula, a one-way valve located at an end of the throughflow body opposite the connection, and, at a distance along the throughflow channel between the connection and the one-way valve, a valve opening is located which is closable by an overpressure valve. The overpressure valve arrangement has at least one elastically deformable valve flap which, in a first state covers the valve opening provided between the connection structure and the one-way valve on the throughflow body and, at a predefinable overpressure occurring inside the throughflow channel converts, by an overpressure-driven elastic deformation of the valve flap, to a second state, in which it at least partially exposes the valve opening.

Abstract: High-bit depth sensors often capture more information then can be displayed on a commercially available display. Due to this, image processing systems and methods are disclosed to ensure that as much information as possible is presented to a user in a meaningful and statistically significant manner. The image processing systems and methods disclosed herein allow a user to view and process data that would otherwise be invisible to the user.
