Abstract: A conformal tattoo biosensor device includes a pattern of sensor regions formed of a conductive polymer. In embodiments, the conductive polymer may have up to six sensor regions. The pattern is electrically connected to a contact region which is electrically connectable to a wearable signal monitor. The monitor is suitable for transmitting ECG, EEG, or EMG signals. In a monitoring system, the monitor wirelessly transmits signals to a mobile communication device for processing. The mobile communication device transmits signals to a monitor network which may include medical personnel and caregivers. A network module may allow automatic medical alerts, monitoring, and further signal processing.

Abstract: A tight control device (1) for the transmission of a rotary motion from a primary shaft (3) to a secondary shaft (5), allowing the volume (P) housing the primary shaft (3) to be separated in a tightly manner from the volume (S) housing the secondary shaft (5), said device comprising a couple of sloped parallel rotating plates (7, 11), each one being fixed to a corresponding one of said shafts (3, 5), interconnected by means of oscillating parallel rods (9), articulated to corresponding C-shaped cages (13, 21) arranged around said plates (7, 11), in order to allow said plates (7, 11) to rotate therein.

Abstract: The present invention relates to a stuffing comprising a case (3a) provided with an axial hole (3afor the passage of a stem (103) being mobile with respect to said case (3); a gasket or packing (5) arranged in a seat (3b) formed within said hole (3a) between said case and said stem; and a stuffing box (7) for compressing said packing (5) between said case (3) and said stem (103), wherein releasable means (11) are provided to perform an axial thrust on said stuffing box (7), so as to cause a compression of said packing (5) between said case and said stem.

Abstract: A method for producing multilayer seals and multilayer seals thereby obtained, wherein the pressure in the volume between the layers is brought to a preset value, at least one of the faces between the layers being provided with channels (3), said method comprising forming at least one channel (3) on at least one face of said layers by which the seal is subsequently made.
