Patent number: 11867771Abstract: Methods and devices for detecting electrical arcs are provided. A first wavelet transformation with a first mother wavelet is applied to a chronological sequence of current measurements (80) of a current through a lead, to obtain first wavelet coefficients. In addition, a second wavelet transformation with a second mother wavelet different from the first mother wavelet is applied to the chronological sequence in order to obtain second wavelet coefficients. On the basis of the first wavelet coefficients and the second wavelet coefficients, it is then determined whether an arc (10; 11; 24) is present.Type: GrantFiled: January 31, 2022Date of Patent: January 9, 2024Assignee: Infineon Technologies AGInventors: Felix Kaiser, Christoph Grund, Goran Keser, Christopher Roemmelmayer

Patent number: 10714795Abstract: Techniques for monitoring an internal pressure of a battery cell, whereby a membrane that is part of an outer shell of the battery cell is used as an element of capacitive-based or inductive-based sensor circuitry in order to measure a change of capacitance or inductance under deformation of the membrane from the internal pressure of the battery cell. The change of capacitance or inductance may in turn be used to derive a value for the internal pressure of the battery cell.Type: GrantFiled: May 1, 2017Date of Patent: July 14, 2020Assignee: Infineon Technologies AGInventors: Guenter Schwarzberger, Jens Barrenscheen, Goran Keser, Christopher Roemmelmayer

Patent number: 10313131Abstract: An intermediate servant device connected in a daisy chain configuration with a set of devices is described. The intermediate servant device may be configured to receive, from a previous servant device of the set of servant devices, a request for data, a first response to the request for data, and authentication information for the first response to the request for data. The intermediate servant device may be further configured to generate a second response to the request for data and determine authentication information for the second response based on the authentication information for the first response, the second response, and a key assigned to the intermediate servant device. The intermediate servant device may be further configured to output at least the authentication information for the second response, the first response, and the second response.Type: GrantFiled: January 26, 2017Date of Patent: June 4, 2019Assignee: Infineon Technologies AGInventors: Goran Keser, Phillip Gesien, Guenter Hofer, Marcus Janke
