Abstract: A system and method for locating objects using radio frequency identifiers is provided. Each object to be located by the user has an object unit attached thereto with a RFID transponder. The user carries a proximity unit with a RFID transponder and warning devices. The method comprises: -a controller receives the instruction to locate a specific object; the controller obtains RFID readings, from the main intermediate units associated with location areas, with information about the object units detected; -determining the location area of the object to be located; -sending information to the user about the location area; -detecting the presence of the proximity unit carried by the user when it is within the location area; -repeatedly obtaining, using readings of the RFID signal strength, information about the distance between the proximity unit and the object unit, reporting it to the user using warning devices.

Abstract: System and method for locating objects using radio frequency identifiers. Each object to be located by the user (5) has an object unit (4) attached thereto with a RFID transponder (61). The user (5) carries a proximity unit (3) with a RFID transponder (51) and warning means (52, 54, 55). The method comprises: —a controller (1) receives the instruction to locate a specific object; —said controller (1) obtains RFID readings, from the main intermediate units (2) associated with location areas, with information about the object units (4) detected; —determining the location area of the object to be located; —sending information to the user (5) about said location area; —detecting the presence of the proximity unit (3) carried by the user (5) when it is within said location area; —repeatedly obtaining, using readings of the RFID signal strength, information about the distance between the proximity unit (3) and the object unit (4), reporting it to the user (5) using warning means (52, 54, 55).

Abstract: The present invention describes an ocular device comprising a magnetic eye implant and a ferrofluid. The products of the invention solve the problems of the patients' position and contribute to the increase in the success rate of the surgical procedure for correcting retinal detachment, problems of severe proliferative diabetic retinopathy in those incapable of maintaining posture, of infectious retinitis, problems resulting from traumatisms and endophthalmitis. It is also possible to use the device as an auxiliary surgical element, e.g., for extracting subretinal fluid.
