摘要:
A presence sensor system includes at least one resilient extending member defining an enclosed sensing volume. The sensing volume includes a fluid therein. A pressure within the sensing volume changes upon application of force to the extending member. The presence sensor system further includes a pressure sensor in fluid connection with the sensing volume, a processor system in communicative connection with the pressure sensor and a communication system in communicative connection with the processor system. In a number of embodiments, the presence sensor system is adapted to determine a pressure threshold associated with onset of presence after being placed in use.

A system for monitoring wellness of a person, includes a local system in the vicinity of the person. The local system includes a plurality of sensor systems. Each of the plurality of sensor systems is associated with at least one monitored system to monitor changes in state of the monitored systems caused by activity or lack of activity of the person. The local system further includes a local data communication device in communicative connection with each of the plurality of sensor system to receive data from each of the plurality of sensor systems. The system further includes a remote system in communication with the local data communication device. The remote system includes a processing system to process data from the plurality of sensor system based upon predetermined rules. The local data communication device is programmed to transmit data to the remote system. The data transmitted to the remote system includes information on state history of the monitored systems. The data on state history may, for example, include at least a time of a change in from a first state to a second and data related to duration of the second state.

A self-regulating valve device adapted for use with respiratory equipment of a type which produces a pressurized flow of breathing gas. The valve device affords automatic access to the ambient atmosphere in the event of respiratory equipment malfunction and includes a primary inlet, a secondary inlet and an outlet. The primary inlet is adapted for connection to a ported exhalation valve which, in turn, is connected to one end of an elongated flexible tube, the opposite end of which is connected to a gas flow generator. The outlet, in turn, is connected to the inlet of an oral, nasal or oral/nasal respiratory mask respectively adapted to cover the patient's mouth, nose or mouth and nose. The valve device further comprises a pressure-responsive valve element for regulating gas flow into the inlet of the respiratory mask. In accordance with a further aspect of the invention, there is additionally provided a diffuser element positioned generally at the valve outlet/mask inlet junction. The diffuser element diffuses or disperses the flow of incoming gas (pressurized or ambient) to the mask, whereby the patient's comfort is enhanced while undergoing treatment for sleep apnea, or other respiratory treatment.

A method of managing sleep therapy includes inputting characterization data associated with each of a plurality of patients into a database system stored in a memory system and inputting outcome data associated with each of the plurality of patients resulting from use of one of a plurality of interface systems in sleep therapy. The method further includes determining a management option for sleep therapy for a person via execution of the algorithm based at least in part upon an optimization of at least one outcome parameter for the person predicted by at least one model of the algorithm based at least in part upon characterization data of the person input into the database system.
摘要:
A method of monitoring a space to determine at least one change in state related to at least one activity includes analyzing an amount of water vapor in the air over time and relating a change in the amount of water vapor in the air over time to the at least one change in state. In a number of embodiments, the at least one change in state is related to a kitchen activity which causes a change in the amount of water vapor in the air. Changes in dew point over time may, for example, are determined. In a number of embodiments, changes in dew point over time are determined by measuring temperature and relative humidity over time and determining dew point from measured temperature and measured relative humidity. Changes in dew point over time may, for example, used to identify or distinguish the activity from a plurality of possible activities associated with the change in state. At least one of change in dew point, change in relative humidity and change in temperature over time may be used (either alone or in any combination thereof) to identify the activity associated with the change in state.
