Publication number: 20140194793Abstract: Aspects of the of the disclosure relate to a non-contact physiological motion sensor and a monitor device that can incorporate use of the Doppler effect. A continuous wave of electromagnetic radiation can be transmitted toward one or more subjects and the Doppler-shifted received signals can be digitized and/or processed subsequently to extract information related to the cardiopulmonary motion in the one or more subjects. The extracted information can be used, for example, to determine apneic events and/or snoring events and/or to provide apnea or snoring therapy to subjects when used in conjunction with an apnea or snoring therapy device. In addition, methods of use are disclosed for sway cancellation, realization of cessation of breath, integration with multi-parameter patient monitoring systems, providing positive providing patient identification, or any combination thereof.Type: ApplicationFiled: March 13, 2014Publication date: July 10, 2014Applicant: KAI MEDICAL, INC.Inventors: Robert Haruo Nakata, Isar Mostafanezhad, Scott Tadashi Miyasato, Erik Vossman

Patent number: 8454528Abstract: A radar-based physiological motion sensor is disclosed. Doppler-shifted signals can be extracted from the signals received by the sensor. The Doppler-shifted signals can be digitized and processed subsequently to extract information related to the cardiopulmonary motion in one or more subjects. The information can include respiratory rates, heart rates, waveforms due to respiratory and cardiac activity, direction of arrival, abnormal or paradoxical breathing, etc. In various embodiments, the extracted information can be displayed on a display.Type: GrantFiled: April 3, 2009Date of Patent: June 4, 2013Assignee: Kai Medical, Inc.Inventors: Andrea Yuen, Amy Droitcour, Anders Host Madsen, Byung Kwon Park, Charles El Hourani, Tommy Shing
