Jul 21, 2003
Appl. No.:

10/624051
Inventors:

Marlin H. Mickle - Pittsburgh PA, US
Christopher C. Capelli - Kenosha WI, US
Harold Swift - Gibsonia PA, US
Assignee:

University of Pittsburgh- Of the Commonwealth System of Higher Education - Pittsburgh PA
International Classification:

H01Q001/26
US Classification:

343701, 343703
Abstract:

An inherently tuned antenna has a circuit for harvesting energy transmitted in space and includes portions that are structured to provide regenerative feedback into the antenna to produce an inherently tuned antenna which has an effective area substantially greater than its physical area. The inherently tuned antenna includes inherent distributive inductive, inherent distributive capacitive and inherent distributive resistive elements which cause the antenna to resonate responsive to receipt of energy at a particular frequency and to provide feedback to regenerate the antenna. The circuit may be provided on an integrated circuit chip. An associated method is provided.

Appl. No.:

10/652104
Inventors:

Eric J. Beckman - Aspinwall PA, US
Tody M. Chapman - Pittsburgh PA, US
Cedrick Gilbert Favero - Givors, FR
Christopher C. Capelli - Kenosha WI, US
Harold E. Swift - Gibsonia PA, US

SNF SA - Andreziux Cedex
International Classification:

C07C233/03
US Classification:

564215, 525 43, 526 72, 502402
Abstract:

A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant including at least one cyclic anhydride group to form an ester, and dissociating (or cracking) the ester to synthesize N-vinylformamide and a compound including at least one diacid group. The ester can be dissociated using heat. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, a polymer including at least one cyclic anhydride group, or a solid support to which at least one cyclic anhydride group is covalently tethered. Preferably, the cyclic anhydride is regenerated from the diacid formed in the synthesis of the ester by heating the diacid to dehydrate the diacid. The temperature required to dehydrate diacid groups is preferably higher than the temperature use to dissociate the ester.

International Classification:

C07C 233/03
US Classification:

564215, 502402
Abstract:

A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant comprising at least one cyclic anhydride group to form an ester, and dissociating the ester via heat in a thin film evaporation to synthesize N-vinylformamide and a compound comprising at least one diacid group, the N-vinylformamide separating from the diacid during the thin film evaporation. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, (2-docecen-1-yl)succinic anhydride, exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic anhydride or a polymer including at least one cyclic anhydride group. A process to produce N-vinylformamide comprises the steps of: mixing acetaldehyde, formamide and a source of anhydride in a single reaction vessel, reacting the acetaldehyde, formamide and the source of anhydride in the reaction vessel under pressure, dissociating an ester formed by a reaction between the source of anhydride and hydroxyethyl formamide formed in the reaction vessel to synthesize N-vinylformamide and a compound comprising at least one diacid group.

Appl. No.:

10/967833
Inventors:

Marlin H. Mickle - Pittsburgh PA, US
Christopher C. Capelli - Pittsburgh PA, US
Harold Swift - Gibsonia PA, US
Assignee:

University of Pittsburgh - Pittsburgh PA
International Classification:

H01M 10/44
H01Q 1/26
US Classification:

320101, 320104, 320108, 343701, 343703
Abstract:

A station having a means for receipt of ambient energy from the environment and energizing power storage devices of objects of interest comprising one or more antennae and circuitry for converting said ambient energy into DC power for energizing said power storage devices. The circuitry for converting the ambient energy into DC power may include a rectifier/charge pump. The antenna of the station is tuned to maximize DC energy at the output of the rectifier/charge pump. The station can be used to energize power storage devices including capacitors and batteries that are used in electronic devices, such as cell phones, cameras, PDAs.

US Classification:

3405722, 3405681, 340 101, 3405728, 342173, 342463
Abstract:

A method of identifying an article of interest includes providing one of a plurality of RF antennas each having a non-linear element which may be a rectifying diode and being resident at a different frequency on the article of interest. One RF antenna is interrogated with RF energy of a first frequency and converts the interrogated RF energy into a reflected energy of a different frequency. The reflected energy is sensed and on the basis of the different frequency determining if a specific antenna is present. The non-linear element may be a diode and is preferably a variable non-linear element. In another embodiment, the reflected RF energy is responsive to a change in ambient physical conditions such as pressure or temperature. Corresponding apparatus is provided.
