Abstract: A portable inhalator device includes a housing with a mouthpiece for a user; a gas conduit coupled to the mouthpiece and configured to guide inhaling and exhaling gas flow within the device; a pressure sensor configured to monitor the gas flow in the gas conduit and to provide pressure differential signal for indicating direction of the gas flow through the gas conduit; a detection sensor configured to monitor the gas flow in the gas conduit and to provide characteristics signal for indicating composition of the gas flow through the gas conduit; and a dispenser configured to dispense a drug to the gas conduit.

Abstract: A diver's computer including detectors for measurement and determination of diving parameters, a processor for processing the measured and determined data concerning the diving parameters, and a display for displaying the parameters processed by the processor. The display of the diver's computer includes at least one display part which can be pre-programmed by the operator to display the diving parameter/parameters chosen by the operator. Further, the display includes at least one display part which has been programmed to display the desired parameter/parameters permanently. The display part that can be pre-programmed by the operator can be switched, during diving, momentarily to show other diving parameters as selected by the operator.
