Patent number: 10839279Abstract: Embodiments of the present invention relate to transponder fabrication. In an embodiment, a plurality of antenna elements is applied to a first substrate at a first pitch. A plurality of fully functioning first transponders is positioned on to the first substrate in a manner to each be in electrical communication with an antenna element included in the plurality of antenna elements and thereby forms a plurality of fully functioning second transponders. The plurality of fully functioning first transponders are positioned on a second substrate at a second pitch. The plurality of fully functioning first transponders have a first read range. Second transponders have an increased read range relative to second transponders. The second pitch is greater than the first pitch.Type: GrantFiled: May 6, 2016Date of Patent: November 17, 2020Inventors: Sriram Manivannan, Dan F Scheffer, Kenneth E Fritsch, Jeremy D Smith

Patent number: 9811774Abstract: A transponder comprises a first polymer layer. A radio frequency (“RF”) transponder is affixed to the first polymer layer, wherein the RF transponder includes a processor in electrical communication with a graphene-based antenna. A second polymer layer is formed on the first polymer layer and the RF transponder. The first polymer layer and second polymer layer form an encasement around the RF transponder. The encasement has a hermeticity of about 10?7 to about 10?12 atm·cc/sec. The encasement provides improved impact, temperature, vibration, chemical, and/or corrosion protection to the RF transponder.Type: GrantFiled: March 8, 2016Date of Patent: November 7, 2017Inventors: John S Lettow, Sriram Manivannan, Dan F Scheffer, Kenneth E Fritsch

Publication number: 20160295338Abstract: Embodiments of the present invention relate to graphene-based microphone diaphragms. In one embodiment, a acoustic wave sensor comprises a diaphragm comprised of a graphene-based composition, wherein the diaphragm has a first side at least partially covered with a reflective material. An emitter fiber is positioned proximate to the diaphragm, wherein the emitter fiber transmits light towards the first side. A collector fiber is positioned proximate to the diaphragm, wherein the collector fiber captures at least a portion of light reflected by the first side, wherein the collector fiber is in communication with a detector. A converter is in communication with the detector and converts a signal received by the detector to a digital signal for processing. The portion of light that is captured as a result of diaphragm distortion is different than the portion of light captured in the absence of diaphragm distortion. The graphene-based composition includes graphene sheets.Type: ApplicationFiled: March 31, 2016Publication date: October 6, 2016Applicant: VORBECK MATERIALS CORP.Inventors: JOHN S LETTOW, DAN F SCHEFFER, KENNETH E FRITSCH
