Patent number: 10918329Abstract: Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14, 16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.Type: GrantFiled: September 5, 2017Date of Patent: February 16, 2021Inventors: David John Bassin, John David Oates, Ronald James Huby, Benriah Goeldi

Patent number: 10873271Abstract: A multiple output rectifier achieving effective supply of power to a plurality of loads. The multiple output rectifier converts an AC input signal into a first rectified output signal and a second rectified output signal, wherein the AC input signal has a fundamental period dividing into a first partial period where an AC current flows in a first direction and a second partial period where the AC current flows in a second direction being a reverse direction to the first direction. The multiple output rectifier includes a first input terminal and a second input terminal different from the first input terminal for input of the AC input signal. The multiple output rectifier further includes a common output terminal, a first output terminal, and a second output terminal. The common output terminal, the first output terminal, and the second output terminal are decoupled from each other for operation in a multiple output operative mode.Type: GrantFiled: February 28, 2017Date of Patent: December 22, 2020Assignee: Wiferion GmbHInventors: Johannes Tritschler, Benriah Goeldi

Patent number: 10763701Abstract: A more efficient solution for a detection of operating conditions in an inductive power transfer system and for improved control of the inductive power transfer system. An operating condition at a secondary side of an inductive power transfer system is detected by measuring at least one electric variable at a primary side of the inductive power transfer system which is dynamically coupled to the operating condition at the secondary side of the inductive power transfer system. Then follows an analysis of the at least one electric variable over time at the primary side of the inductive power transfer system. This allows to detect a change of the operating condition at the secondary side of the inductive power transfer system. Also provided is a control method and related controller apparatus using the detection method.Type: GrantFiled: March 10, 2017Date of Patent: September 1, 2020Assignee: Wiferion GmbHInventors: Benriah Goeldi, Johannes Tritschler

Patent number: 10651762Abstract: An efficient solution to the problem of converting alternating signals into a plurality of signals having different signal characteristics in observation of different application requirements. This is achieved by a multiple input multiple output converter operated at a secondary side of an inductive power transfer system for converting at least one alternating input signal into a rectified alternating input signal and a further signal derived by averaging a switched voltage generated during rectification of the alternating input signal. The multiple input multiple output converter comprises at least one rectifier circuit adapted to rectify the alternating input signal and at least one averaging circuit adapted to average the switched voltage which is generated during rectification operation of the eat least one alternating input signal.Type: GrantFiled: April 7, 2017Date of Patent: May 12, 2020Assignee: Blue Inductive GmbHInventors: Johannes Tritschler, Benriah Goeldi
