Publication number: 20230310779Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.Type: ApplicationFiled: April 6, 2023Publication date: October 5, 2023Inventors: Po-Yen Liu, Ivan Chih-Fan Teng, Peter Alan Seekup, Daniel John Smith, Ho Shing Lo

Publication number: 20230016953Abstract: The present disclosure provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two-step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.Type: ApplicationFiled: July 28, 2022Publication date: January 19, 2023Inventors: Po-Yen LIU, Ivan Chih-Fan TENG, Stefan Leo VAN WORKUM, Oliver Samuel STEINER, Anthony James NEWLAND

Publication number: 20200031277Abstract: A method for issuing warnings to a driver as to the presence of objects in the path of his vehicle which are possibly dangerous includes steps of obtaining an image of eyes of a driver and an image of scene in front of the vehicle and detecting coordinate of pupils of the driver's eyes. The pupils coordinate is converted into coordinate of parts or points of the view in front of the vehicle. Any object within a preset distance in front of the vehicle is searched for and if found the method determines whether the pupils coordinate is within or outside a safety range around the object. A warning signal is output when the view coordinate is outside the safety range around the object in the front scene image. An electronic device is also provided.Type: ApplicationFiled: July 25, 2019Publication date: January 30, 2020Inventor: PO-YEN LIU
