Patent number: 10032102Abstract: Excess radio-frequency (RF) power storage in RF identification (RFID) tags, and related systems and methods are disclosed. The RFID tag is configured to operate with RF power received in wireless RF signals from a RFID tag antenna if received RF power meets or exceeds an operational threshold power for the RFID tag. The RFID tag is also configured to store excess energy derived from excess received RF power in an energy storage device if the received RF power exceeds the operational threshold power for the RFID tag. Thus, when RF power received by the RFID tag is not sufficient for operation, the RFID tag can operate from power provided by previously stored excess energy in the energy storage device.Type: GrantFiled: March 15, 2013Date of Patent: July 24, 2018Assignee: Fiber Mountain, Inc.Inventors: John David Downie, Leo Nederlof, James Scott Sutherland, Mark Peter Taylor, Richard Edward Wagner, Matthew Scott Whiting

Patent number: 9841555Abstract: Optical transmission systems and methods are disclosed that utilize a QSM optical fiber with a large effective area and that supports only two modes, namely the fundamental mode and one higher-order mode. The optical transmission system includes a transmitter and a receiver optically coupled by an optical fiber link that includes at least one section of the QSM optical fiber. Transmission over optical fiber link gives rise to MPI, which is mitigated using a digital signal processor. The QSM optical fiber is designed to have an amount of DMA that allows for the digital signal processor to have reduced complexity as reflected by a reduced number of filter taps as compared to if the DMA were zero.Type: GrantFiled: September 23, 2015Date of Patent: December 12, 2017Assignee: Corning IncorporatedInventors: John David Downie, Ming-Jun Li, Michal Mlejnek, Ioannis Georgios Roudas, William Allen Wood, Aramais Robert Zakharian
