Patent number: 11398648Abstract: The system (4) is provided for managing at least one sub-assembly (2) of an electric battery. Each sub-assembly comprises a plurality of power storage cells (12). The system includes, for each power storage cell, a circuit (14) for managing the state of the cell and a communication circuit (16), which is configured such that it receives and transmits data relative to the cell. The communication circuit is configured such that it transposes, over a carrier frequency, the data to be received and transmitted, the value of said carrier frequency being greater than or equal to 1 GHz. The management system further includes, for each sub-assembly, a loss cable (18) connecting the power storage cells of said sub-assembly. The loss cable acts as a waveguide and is coupled by capacitive coupling to the communication circuit of each power storage cell.Type: GrantFiled: September 24, 2019Date of Patent: July 26, 2022Assignee: EM Microelectronic-Marin SAInventors: Thierry Scordilis, Jerome Saby, Arnaud Casagrande, Luca De Rosa

Patent number: 8624774Abstract: The invention concerns a method and system of locating objects by means of UWB signals, the system including a search device (D1), incorporated in a portable apparatus (11) and provided with a pair of antennae (A1, A2), and at least one target device (D2) attached to an object sought (12). The target device (D2) includes, in addition to the transceiver (34, 35), a very low power consumption wake up receiver (46) which, when the target device is in a standby state, can receive a UWB wake up signal to switch on said device. This target device is arranged for measuring a time difference (tdiff) between the respective receptions of two locating signals respectively emitted by the two antennae (A1, A2) of the search device and for transmitting said time difference in a return signal that further contains, in a preferred variant, a signal processing time (trproc). Thus, it is not necessary for the two devices to be synchronized.Type: GrantFiled: March 17, 2011Date of Patent: January 7, 2014Assignee: The Swatch Group Research and Development LtdInventor: Luca De Rosa
