Patent number: 11890568Abstract: An air purifier filter system comprises an air purifier filter unit and a machine readable identifier which provides information concerning the filter unit type and performance information specific to a target pollutant to be filtered by said air purifier filter unit from a plurality of different pollutants that can be filtered by that filter unit type. This information can be used to provide an end of life prediction for the filter unit or provide advice that the filter should be changed for other reasons. This enables the user to be given advance warning, and to be given instructions when it is time to change the filter unit. The instructions to change the filter unit may be more accurate than a simple timer as they can take account of the type of filter unit and the performance information. In some examples the use history of the filter unit may also be used to predict the time when it should be changed.Type: GrantFiled: December 15, 2015Date of Patent: February 6, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hendrik Richard Jousma, Declan Patrick Kelly, Einte Holwerda, Jean-Paul Jacobs, Cornelis Reinder Ronda, Jean Bart Bleeker, Koray Karakaya

Patent number: 11555626Abstract: A ventilation unit is for ventilating an indoor space, and incorporates an air cleaning device and mechanical restrictor for controlling a restriction to a flow resulting from a pressure differential across the unit. There is determination of the inside and outside air pressures in the vicinity of the unit and of air quality parameters inside and outside. The air cleaning device and the mechanical restrictor are controlled in dependence on the determined air pressures and air quality parameters. This provides a fan-less, and hence low-power ventilation unit, which relies on throttling the natural air flow across the unit to provide flow control, and hence enable control of air quality. The air cleaning device may be operated only when the flow is into the inside space, saving power.Type: GrantFiled: August 1, 2018Date of Patent: January 17, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Johannes Marra, Achim Gerhard Rolf Koerber, Cornelis Reinder Ronda

Publication number: 20220322954Abstract: An optical analysis of saliva or a fluid-saliva mixture is performed in order to check whether the saliva or fluid-saliva mixture contains blood, which allows for determining whether or not a person may suffer from gingivitis or another condition affecting gum health. Light received from a representative volume of fluid (23) containing saliva is detected and analyzed. The analysis involves determination of at least one measurement value of light received by a light-receiving unit (25) for only a single wavelength of the light, particularly a wavelength that is associated with high absorption by a constituent of blood. It this respect, it is practical if the light-receiving unit (25) is configured to receive reflected light back from the volume of fluid (23). The optical analysis may be performed real-time during an action in a person's mouth involving a gum agitation effect, or after such action has taken place, for example.Type: ApplicationFiled: August 14, 2020Publication date: October 13, 2022Inventors: Cornelis Reinder RONDA, Olaf Thomas Johan Antonie VERMEULEN, Lucas Petrus Henricus SCHEFFERS

Patent number: 11413628Abstract: An electrostatic air cleaning device comprises a particle charging section, a particle precipitation section, a current sensor for measuring an electric current flowing through electrode plates of the precipitation section and a relative humidity sensor. The voltage applied to the electrode plates and the air flow through the device are controlled in dependence on the measured current flowing through the electrode plates. In this way, control is provided to prevent excessive electric leakage currents inside the precipitation section, that may lead to a hazard, and to optimize the energy efficiency of the cleaning device in relation to its cleaning performance. The relative humidity information also enables diagnosis of the cause of the high leakage current and the status of the precipitation section concerning the amount of precipitated particles therein.Type: GrantFiled: December 1, 2017Date of Patent: August 16, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Johannes Marra, Achim Gerhard Rolf Koerber, Cornelis Reinder Ronda
