Abstract: A system and method for managing a respiratory condition of a user is disclosed. The system includes an oxygen concentrator having a compression system configured to generate oxygen enriched air for delivery to the user. A physiological sensor is configured to collect physiological data of the user. The physiological data is of one or more data types. An operational sensor is configured to collect operational data of the oxygen concentrator during operation of the oxygen concentrator. The operational data is of one or more data types. A processor is configured to receive the collected physiological data and the operational data and compute a summary parameter for values of each data type. The processor is also configured to compute a health score from the summary parameter values.

Abstract: A method and system of responding to adverse environmental conditions local to a user of an oxygen concentrator is disclosed. Physiological data of the user is collected. Operational data of the oxygen concentrator is collected during operation of the oxygen concentrator. Environment data local to the oxygen concentrator is collected. Based on the collected environmental data, it is determined whether adverse environmental conditions exist local to the oxygen concentrator. The collected physiological, operational, and environmental data are analyzed to determine a responsive action to the determined adverse environmental conditions. The responsive action is communicated to the user.

Abstract: A user-replaceable receptacle for an oxygen concentrator includes a containment structure and a desiccant disposed within the containment structure. An inlet end of the containment structure allows feed gas to be introduced into the desiccant. An outlet end of the containment structure allows the feed gas to exit the containment structure. A connection mechanism couples the outlet end of the containment structure to a gas separation adsorbent. The connection mechanism is operable between an unconnected position and a connection position. The desiccant in the user-replaceable receptacle removes water moisture from the feed gas prior to exiting the outlet end of the containment structure, thereby reducing exposure of the gas separation adsorbent to water.

Abstract: Various embodiments are configured to detect a foreign object that has been implanted into or onto a device, such as a secure POS terminal. The implanted object can be a device that is designed to skim data (such as account information from a transaction card or other transaction device) and transmit the skimmed data to a nearby receiver using an RF transmission, such as Bluetooth or WIFI. The RF transmission can be detected by a RF detector in the POS terminal, the detected signal is converted to a voltage signal, and is input to the ADC port of a microprocessor where it is subsequently analyzed to determine if the RF transmission is from a foreign object. The POS terminal may forward collected data on the RF transmission to a cloud/backend server. Further analysis may occur at the cloud/backend server.

Abstract: In an embodiment, a hearing aid is provided. The hearing aid may include a behind-the-ear component, a sound tube coupled with the behind-the-ear component at its one end, and a loudspeaker coupled with the sound tube at the other end of the sound tube opposite to the behind-the-ear component. The hearing aid may further include a joint connected between the loud-speaker and the sound tube, wherein the joint is moveable or flexible such that a degree of freedom in movement is provided in a direction substantially perpendicular to an insertion direction of the loudspeaker into an ear canal.

Abstract: The wearing comfort of a hearing device designed as a mass-produced product, in particular a hearing aid, is improved. The hearing device is provided to be carried in an auricle. It comprises a housing which houses a sound signal processing device. A conductor conducts an acoustic or electric signal from the housing into an auditory canal of the user. A mold, which is individually fitted to a portion of the auricle of the user and provided with the housing in the form of a two-part design, is attached to the housing. The mold evenly distributes the pressure which the hearing aid exerts on adjacent sections of the auricle.
