| 发明名称 | RFID presence detection device | ||
| 摘要 | A presence detection device (10) for detecting the presence of an object (24) in a determined detection area, comprising at least one RFID tag (12A, 12B) that emits an identification signal at a determined RFID frequency; an RFID interrogator (16) receptive of the identification signal via at least one antenna (18); and an insulating plate (20) electromagnetically shielding the antenna from a direct emission of the identification signal,;wherein the presence of the object in a determined detection area results from the reception by the RFID interrogator after being reflected by the object of the identification signal emitted by the corresponding RFID tag. | ||

| 主权项 | 1. A presence detection device (10) for detecting the presence of an object (24) in a determined detection area (22A, 22B; 30A, 30B), comprising: at least one RFID tag (12A, 12B; 12) that emits an identification signal at a determined RFID frequency; at least one antenna (18; 18A, 18B); an RFID interrogator (16) receptive of the identification signal via said at least one antenna (18; 18A, 18B); and an insulating plate (20) electromagnetically shielding said at least one antenna from a direct emission of the identification signal of said at least one RFID tag, wherein the presence of the object in a determined detection area results from the reception by the RFID interrogator of the identification signal emitted by one of said at least one RFID tag after being reflected by the object. | ||
