Maryland Patent of the Month – September 2022

Continuous monitoring of respiration and heart rate is essential for early detection of potentially fatal diseases. Typically, devices used to monitor these functions involve wires attached to the body or wearing bands containing sensors, which can be uncomfortable. Wireless devices used to detect human vital signs often have WiFi technology with a low carrier frequency, which makes it difficult to detect changes in the breathing of an individual in large areas. In addition, WiFi signals are often scattered by other individuals, devices, and objects in the environment, making it difficult to estimate the individual’s heart rate due to the low signal-to-noise ratio obtained.  

Origin Wireless, Inc. aims to provide an accessible solution to users who may live alone, and may need additional respiratory or heart rate monitoring without compromising mobility or comfortability. The company makes use of artificial intelligence software and WiFi technology to sense changes in breathing patterns and heart rate before alerting a specified list of people, such as close family members of these changes.

Their wireless monitoring system consists of a transmitter, receiver, and processor. The transmitter emits a wireless signal while the receiver extracts a time series of information, or a sequence of data. This data provides information in regards to the location of the individual, changes in movement, and contraction or compression of the body. The processor detects irregular changes in breathing and heart rate patterns even in large spaces, and presents this information in the form of a visual, audio, or text representation. This innovative WiFi sensing technology allows caregivers to monitor their patients without wearable devices, cameras or other devices, maintaining the individual’s privacy and peace of mind.
