Philippe Held has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9704092
    Abstract: The invention concerns a security sealing device including a sealing element, an integrated circuit and an antenna connected to the integrated circuit, the integrated circuit and the antenna forming a RFID circuit. The security sealing device is characterized by the fact that said sealing element is conductive and is forming a part of said antenna.

  • Publication number: 20070290859
    Abstract: A support (1) has at a least one accommodation position (3) for removably accommodating an article (2) marked with a transponder (12) comprising a transponder chip (13) and an antenna (14) electrically connected to the chip. Each accommodation position comprises an inductive coupling unit (5) with a primary antenna (6) and a secondary antenna (7) connected in series and wherein the secondary antenna (7) is configured such that, when the accommodation position is accommodated with an article, the secondary antenna (7) is inductively coupled with the antenna (14) of the transponder.

  • Patent number: 6848621
    Abstract: A transponder unit which can be integrated in a transport unit or a card or the like. The transponder unit includes, in addition to an encapsulated transponder of an integrated circuit, an aerial winding having a resistance RA and a capacitor parallel thereto and having a capacitance CA. A closed coupling circuit of secondary winding is coupled with the aerial winding by a mutual inductance MSA and a substantially larger primary winding in series with the secondary winding and having fewer turns, for example only one turn. To achieve almost optimum energy transfer between a reading device and the transponder and to increase the permissible reading distance, the mutual inductance MSA is adjusted to comply with the relationship MSA=?{square root over ( )}[RA/?) (LP+LS+2MPS)], where ?2=1/(LACA) is true for the receiving frequency ? of the transponder and Lp and LS are the inductances of the primary winding and of the secondary winding and MPS is their mutual inductance.
