The embodiments described herein relate generally to medical devices that measure vital signs, and more particularly to wearable wireless devices that collect multiple simultaneous vital signs, and systems and methods for compressing the sensor data into a matrix representation to facilitate collecting, transmitting, processing, and displaying vital sign data.

A system and associated methods use an animal harness attached to an animal to improve security at a location (e.g., a home, office, warehouse, etc.). The animal harness collects health status data of the animal, and the health status data is processed using one or more algorithms that detect changes in one or more of excitement, agitation, stress, and/or anxiety in the animal. These changes are interpreted, using a behavioral model of the animal, to determine whether the animal is witnessing a security event at the location, and when the health status data indicates the security event, the system may generate an alert. The behavioral model may be updated over time to improve performance of the algorithms to detect security events.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

A system and method are provided for diagnosis of animal respiratory diseases using auscultation techniques. Animal lung sounds are recorded and digitized. Lung sounds are obtained by an electronic digital stethoscope or a wireless audio digital recording unit. The sounds are stored as digital data, and one or more algorithms are applied to the data for producing an output to the user indicative of the health of the animal. The acoustic characteristics of the sound are compared with baseline data in the algorithms. One embodiment includes a digital stethoscope with an integral display. Another embodiment provides a system for gathering information about an animal to include not only auscultation data, but also information from other field devices such as temperature probes or weigh scales. The combined information can be analyzed by system software to generate detailed information to a user to include a diagnosis and recommended treatment options.

A system for monitoring the cardiopulmonary functioning of a person includes a remote terminal and a sensor module configured to be worn by the person. The sensor module includes at least one physiological sensor configured to sense the following types of physiological information generated by the person: pulse rate, blood flow, and blood pressure; at least one signal processor configured to process signals generated by the at least one physiological sensor; and at least one transmitter responsive to the at least one signal processor that is configured to transmit at least one signal to the at least one remote terminal. The at least one signal processor is configured to focus processing resources on one of the types of physiological information in response to a specified preference by the person.

A sensor, sensor pad and sensor array for detecting infrasonic signals in a living organism are provided. The sensor, sensor pad and/or array can be utilized for detecting, determining and/or diagnosing level of stenosis, occlusion, or aneurysm in arteries, or other similar diagnosis. The sensor can include unique circuitry in the form of a piezoelectric plate or element sandwiched between two conductive O-rings.
