Abstract: A breathing apparatus includes a source of compressed air and a lung demand valve that receives compressed air from the source. A pneumatic valve assembly is connected between the source and the lung demand valve. The pneumatic valve assembly is moveable between a first closed position that prevents a flow of compressed air to the lung demand valve and a second open position that provides a path for compressed air to flow to the lung demand valve. A mask receives the lung demand valve therein. The mask provides the compressed air to a user and having a first operational mode providing filtered ambient air to the user and a second operational mode providing compressed air to the user. A control device is coupled to the pneumatic valve assembly. The control device detects a condition in the air surrounding the apparatus and controlling the pneumatic valve assembly to move between the first closed and second open position and the mask to operate in a respective one of the first and second operational modes.

Abstract: An apparatus and method is provided that identifies the presence or absence of a P-wave within a set of ECG data. A computation processor identifies the R-wave and then analyses a section of the waveform within a predetermined time window preceding the detected R-wave peak. The waveform within the window is analysed to identify a candidate P-wave, and in response to identifying the candidate P-wave a first and second feature associated therewith is measured. A composite feature value is calculated from the first and second measures, and compared to a classification threshold value. In an exemplary embodiment, the first feature represents a height between a highest peak of the candidate P-wave and a trough of the Q-wave, and the second feature represents a time between the peak of the candidate P-wave and a peak of the R-wave.

The display forms part of a medical data display system utilizing data from at least one sensor monitoring one or more physiological parameters of a patient. The graphical user interface separately displays at least two waveforms derived from the at least one sensor. Thereafter, user-generated input is received via the touchscreen interface of the display that includes at least one gesture selecting a waveform at a first location and terminating at a second location within the graphical user interface. Subsequently, the selected waveform is moved from the first location to the second location within the graphical user interface based on the at least one gesture. Related apparatus, systems, techniques and articles are also described pertaining to the movement of components in a graphical user interface of a medical data display system.

Abstract: A first wireless connection is initiated between a station and a first access point (410). During this first wireless connection, data packet traffic is monitored from other access points (420). It is repeatedly determined (430), by the station using the monitored data packet traffic and during the first wireless connection, which of the other access points provides a best data transmission profile. Thereafter, the station automatically transitions (440) from the first wireless connection to a second wireless connection with the access point having the most recently determined best data transmission profile upon occurrence of a trigger event or a termination of the first wireless connection. Related apparatus, systems, methods and articles are also described.
