Patent number: 10682083Abstract: A sensor system comprises first and second PPG sensors. A monitoring system monitors detection by at least one of the first and second detectors an optical calibration signals, for performing time calibration between the first and second PPG sensors. This system makes use of two PPG sensors. To enable these sensors to be independent units, rather than being fully integrated into a combined system, a calibration system is provided. Based on detected optical signals, the behavior over time of each PPG sensor can be monitored and thus calibration can take place.Type: GrantFiled: June 22, 2016Date of Patent: June 16, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Sam Martin Jelfs, Jozef Hubertus Gelissen, Reinder Haakma, Laurentia Johanna Huijbregts, Adrianus Petrus Johanna Maria Rommers

Patent number: 10090884Abstract: A power transmitter for transferring power to a power receiver using a wireless inductive power signal includes a power source provides a power source signal which may have level variations. A power signal generator generates a drive signal from the power source signal by a frequency converter which increases the frequency of the drive signal relative to the power source signal. A limiter restricts the power of the drive signal fed to the inductor to be below a threshold in repeating time intervals. A synchronizer synchronizes the repeating time intervals to the power source signal. In the power receiver, an inductor receives a power signal from the power transmitter, a load coupler decouples the power load from the inductor during the repeating time intervals and a synchronizer synchronizes the repeating time intervals of the receiver to the power signal. Communication units exchange data during the repeating time intervals.Type: GrantFiled: December 30, 2013Date of Patent: October 2, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Wilhelmus Gerardus Maria Ettes, Klaas Jacob Lulofs, Adrianus Petrus Johanna Maria Rommers, Neil Francis Joye, Andries Van Wageningen

Publication number: 20150341085Abstract: A power transmitter (501) transfers power to a power receiver (505) using a wireless inductive power signal between inductors of the devices. In the power transmitter (501) a power source (601) provides a power source signal which may have level variations. A power signal generator (603) generates a drive signal from the power source signal by means of a frequency converter (605) which increases the frequency of the drive signal relative to the power source signal. A limiter (607) for restricts the power of the drive signal fed to the inductor (503) to be below a threshold in repeating time intervals. A synchronizer (611) synchronizes the repeating time intervals to the power source signal. In the power receiver(505) a load coupler (1001) decouples the power load (1003) from the inductor (507) during the repeating time intervals and a synchronizer (1005) synchronizes the repeating time intervals of the receiver to the power signal.Type: ApplicationFiled: December 30, 2013Publication date: November 26, 2015Inventors: Wilhelmus Gerardus Maria ETTES, Klaas Jacob LULOFS, Adrianus Petrus Johanna Maria ROMMERS, Neil Francis JOYE, Andries VAN WAGENINGEN

Patent number: 8723532Abstract: A capacitive proximity device for sensing a presence and/or absence of an object in the proximity of an electronic device includes an emission electrode capacitively coupled to a receiver electrode, an oscillator for generating an emission-signal being an alternating electric field between the emission electrode and the receiving electrode, and a sensing circuit connected to the receiving electrode. The sensing circuit receives a measured-signal from the receiver electrode and includes a first synchronous detection circuit together with a low-pass filter for generating an output-signal being proportional to a distance between the object and the electronic device. The sensing circuit further includes a noise-suppresser for reducing noise from the measured-signal before entering the first synchronous detection circuit.Type: GrantFiled: June 10, 2009Date of Patent: May 13, 2014Assignee: Koninklijke Philips N.V.Inventors: Ronald Jan Asjes, Adrianus Petrus Johanna Maria Rommers, Henricus Antonius Verspaget, Cristian Presura, Antonius Hermanus Maria Blom
