Publication number: 20230165478Abstract: An apparatus (10) is for use in monitoring uterine contractions. Means are provided for separately detecting (18) solid (e.g. flush) contact of at least a portion of a sensor unit (14) of the apparatus on the abdomen, and for a detecting (20) an initial starting pressure, or a baseline pressure, between the sensor unit and the abdomen. A controller (24) is arranged to first sense contact of said at least portion of the sensor unit on the abdomen, and then responsive to the contact detection, detect the starting pressure using an integrated pressure sensor. The same pressure sensor is preferably used for monitoring the uterine contractions. The starting pressure provides a direct or indirect measure or indication of the tension of a belt which is arranged in use to hold the apparatus against the abdomen of the subject.Type: ApplicationFiled: May 6, 2021Publication date: June 1, 2023Inventors: ROMAN YERMOSHKIN, MARKUS SILVESTER WOHLSCHLAGER, HANSJOERG GEYWITZ

Patent number: 11583256Abstract: The present invention is directed to a method for health monitoring using one or more sensors comprising first measuring (100) a body composition via one or more sensors. The measured body composition is then classified (102) into one of a plurality of categories. An at least one setting to be used for the health monitoring is adjusted (104) based on the classified body composition. Then, the health monitoring is performed (106) using the adjusted at least one health monitoring setting, wherein at least one of the sensors used to measure the body composition may also be used to perform the health monitoring.Type: GrantFiled: June 20, 2017Date of Patent: February 21, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Markus Wohlschlager, Hansjoerg Geywitz

Patent number: 11452004Abstract: The present disclosure relates to apparatuses and a method for wireless health monitoring comprising dynamically adjusting sound data compression level and/or transmission bandwidth of transmission between a mobile transmitter and a receiver. In some embodiments, a method for wireless health monitoring may include calculating (202) a distance between a mobile transmitter (104) and a receiver (110). A data compression (108) level for compressing a signal, e.g., a sound signal, from the transmitter may be determined out of a plurality of data compression levels based on the distance between the transmitter and the receiver. A transmission bandwidth may then be determined (208) based at least in part on the determined data compression level. The compressed signal may be transmitted (210) using the determined transmission bandwidth.Type: GrantFiled: November 1, 2017Date of Patent: September 20, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hansjoerg Geywitz, Markus Wohlschlager

Patent number: 11382598Abstract: The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal, which comprises at least two channels, including a first channel obtained for a first depth range and a second channel obtained for a second depth range. A first heart rate is determined from the first channel (51, 53, 55) and a second heart rate is determined from the second channel (52, 54, 56). External information on the fetal heart rate and/or the maternal heart rate, extracted from an independent source (60, 61, 62) such as an ECG, is used to select one of the first heart rate and the second heart rate as the fetal heart rate to be determined. A preferred embodiment provides for elimination of double counting heart rates by cutting out unwanted signal contributions. The disclosure further provides for an adaptive signal processing and data acquisition controlled by patient related data.Type: GrantFiled: September 13, 2016Date of Patent: July 12, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Markus Wohlschlager, Hansjoerg Geywitz

Publication number: 20220166529Abstract: A method and communications module for recommending in what manner or mode a sensor and communications module of a subject monitoring system should communicate. A determination is made as to whether or not more than a predetermined number of wireless channels have a noise level below a certain threshold. If a positive determination is made, a wireless communication mode is recommended. If a negative determination is made, a wireless communication mode is not recommended.Type: ApplicationFiled: March 4, 2020Publication date: May 26, 2022Inventors: Markus Silvester WOHLSCHLAGER, Hansjoerg GEYWITZ, Daniel GAL

Publication number: 20220071552Abstract: An apparatus (12) for placement on the abdomen of a subject for monitoring uterine contractions. The apparatus includes a light source (16) and a light detector (18) which communicate light via a reflection surface (22) arranged facing the light source and light detector. One of the light source and light detector is fixed in position relative to the reflection surface, while the other is arranged to be displaceable relative to the reflection surface responsive to movement of the subjects abdomen caused by contractions. The movement of the moveable component is such as to cause a variation in the light intensity received at the light detector, the variation in light intensity being representative of the uterine contractions.Type: ApplicationFiled: May 19, 2020Publication date: March 10, 2022Inventors: ROMAN YERMOSHKIN, HANSJOERG GEYWITZ, MARKUS SILVESTER WOHLSCHLAGER

Patent number: 11266375Abstract: The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal. Rather than extracting the Doppler signal from the carrier signal using synchronous demodulation, quadrature demodulation is used, which allows to distinguish between systolic and diastolic movements. This velocity direction can be used to cut out unwanted parts of the signal (systolic or diastolic heart activity), thus eliminating double counting heart rates. In particular, a binary sign signal (15?) may be used to cut out unwanted signal episodes, resulting in a processed reference signal (10?) having only the signal parts of one heart activity. Another aspect relates to determining a first and a second heart rate from at least two channels having a different depth range, and selecting one of the first and second heart rate based on external information of the fetal or maternal heart rate.Type: GrantFiled: August 30, 2016Date of Patent: March 8, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Markus Wohlschlager, Harry Beitinger, Hansjoerg Geywitz

Patent number: 11234061Abstract: The invention relates to a communication device (8) for wirelessly communicating with a sensor (4). The communication device (8) comprises a receiver for receiving signals, an amplifier for amplifying the received signals, a transmitter for transmitting signals, and a controller. The controller is operable in a first mode in which signal strength values are determined over time, which are indicative of a strength of an amplified received signal, and in a second mode in which signal transmission and reception are controlled based on the determined signal strength values. The determined signal strength values can be indicative of, for instance, a saturation of the amplifier caused by a transmission operation of another, neighboring communication device such that, by considering the determined signal strength values, the transmission carried out by the communication device (8) can be synchronized with the corresponding operation of the neighboring communication device. This can lead to reduced disturbances.Type: GrantFiled: April 30, 2019Date of Patent: January 25, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Markus Wohlschlager, Hansjoerg Geywitz, Daniel Gal, Andre Bigalke
