  • Patent number: 11779266
    Abstract: A portable polysomnography apparatus comprises a unitary flexible structured pillow that is embedded with one or more sensors for data collection. The one or more sensors can comprise a tilt sensor that is configured to generate respiratory effort signals based on tilting of the head of the subject on the pillow. The one or more sensors can further be configured to generate ballistocardiogram signals from movement of the head of the subject caused by beating of the heart of the subject. The polysomnography apparatus can be advantageously sized and shaped to cause the sleeping subject to properly orient her head with respect to the sensors for optimal data collection while the subject is asleep.

  • Patent number: 10856800
    Abstract: A portable polysomnography apparatus comprises a unitary flexible structured pillow that is embedded with accelerometers for data collection. The polysomnography apparatus is advantageously sized and shaped to cause the sleeping subject to properly orient the embedded accelerometers for optimal data collection while the subject is asleep. A portable polysomnography system comprises a structured pillow with embedded sensors that are in wireless communication with a companion data collection device that records data from the embedded sensors. In an alternative embodiment, a system may include a structured pillow with an internal pocket into which a single device including embedded sensors and data recording capabilities is inserted.

  • Patent number: 6485441
    Abstract: A mattress device provides a high information variety from a low number of sensors configured and placed in correspondence with a mattress core layer and a mattress top layer of the mattress device in order to monitor a patient's sleep behavior. Mattress core and top layers provide a static position transmission characteristic and a dynamic impulse transmission characteristic enabling the sensors to recognize body imprint position and body impulses induced by the sleeping patient with a broad bandwidth. In an alternate embodiment, the mattress device may be combined with a signal coder capable of receiving signals or signal components from the sensors and transform them in an analog signal that can be received and processed by a conventional sound card of a computer. A decoding program installed on the computer decodes the alphanumeric information processed from the analog signal by the sound card and makes it available for further interpretation.
