Patent number: 9179203Abstract: Optical devices in optical network exchange signals at a plurality of wavelengths via a plurality of pathways. Each of the optical devices is associated with a corresponding wavelength and includes multiple optical inputs/outputs (I/Os) to exchange signals at the corresponding wavelength via the plurality of pathways. During maintenance or failure of one of the optical I/Os in an optical device associated with a wavelength, communications are maintained in the optical network by switching communications at a same wavelength to another a different pathway and/or reforming the optical network using other wavelengths. For example, an optical network unit (ONU) may identify an error in a first wavelength associated with a first optical device included in an optical line terminal (OLT) and may forward data using a second wavelength associated with the other optical device included in the OLT.Type: GrantFiled: September 30, 2013Date of Patent: November 3, 2015Assignee: VERIZON PATENT AND LICENSING INC.Inventor: Vincent O'Byrne

Publication number: 20080021534Abstract: The present invention relates to a balloon expandable stent mounted on a balloon catheter, the entire assembly being overcoated with a coherent polymer coating, which is preferably substantially continuous over the circumference and, more preferably, axial length of the stem on the balloon. The polymer coating improves retention of the stent on the balloon during delivery and does not adversely effect the deployment characteristics, nor the balloon failure characteristics. The product is made by mounting the stent on the balloon and coating the assembly with a liquid coating composition containing a suitable polymer followed by curing of the coating. The polymer is biocompatible and preferably crosslinkable in the coating composition, and crosslinked in the final product. A suitable polymer is formed from monomers including a zwitterionic, preferably a phosphoryl choline, group, and monomers including a trialkoxysilyl group.Type: ApplicationFiled: July 23, 2007Publication date: January 24, 2008Applicant: Abbott Vascular, Inc.Inventors: Peter Stratford, Alistair Taylor, Vincent O'Byrne, John Clarke, Denis Healy

Patent number: 6882846Abstract: A system increases the capacity of a CDMA network having a plurality of cell sites. The system defines a pool of frequencies available for assignment, and assigns one of the available frequencies to each of the cell sites so as to minimize the number of neighboring cell sites assigned a same one of the available frequencies. By deploying different frequencies in the cell sites, the amount of interference caused by neighboring cell sites reduces. As a result, the capacity of each of the cell sites operating at a single frequency can be increased, so long as there remains sufficient power to reach the mobile units operating within the cell site. The system attains maximum benefits when the cell sites are located close together and the propagation exponent is low (for example, 10-20 dB/decade).Type: GrantFiled: June 22, 2000Date of Patent: April 19, 2005Assignee: Verizon Laboratories Inc.Inventor: Vincent A.

Patent number: 6549781Abstract: A system (200) provides a network designer with a mechanism by which to quickly estimate the performance of a code division multiple access wireless communication network. The system (200) allows the designer to enter a group of network and sector parameters. Based on these parameters, the user can choose one of three methods depending on a desire for speed, accuracy, and generality of result. The system (200) determines the pilot strength and interference for each location in the network. The system (200) determines pilot strength to interference values for each location. The system (200) estimates the performance of the communication network using these determined values and accounting for user-defined network parameters.Type: GrantFiled: April 12, 2000Date of Patent: April 15, 2003Assignee: Verizon Laboratories Inc.Inventors: Vincent A.

Patent number: 6393302Abstract: A cellular network includes first cell sites having a first layout and second cell sites, interspersed among the first cell sites, having a second layout. The layout refers to the orientation of the antennas in the cell sites. By making the second layout different than the first layout, the amount of interference in the network reduces and, thus, the capacity of the network increases.Type: GrantFiled: March 5, 1999Date of Patent: May 21, 2002Assignee: Verizon Laboratories Inc.Inventor: Vincent A.

System and method for determining guard zone and guard bands in a digital cellular dual mode network
Patent number: 5960329Abstract: An interference analyzing system and method analyze interference in a dual mode system having a digital network overlaid on an analog network. The digital network includes portable units operating within digital cell sites; whereas, the analog network includes mobile units operating within analog cell sites. The interference analyzing system measures the amount of interference caused by and to the portable units, and the amount of interference caused by and to the digital cell sites. The system individually compares these interference amounts to a predetermined threshold. If either of the interference amounts exceeds the predetermined threshold, the system selects one of the analog cell sites for spectrum clearing and determines the amount of spectrum to be cleared from the selected analog cell site.Type: GrantFiled: September 26, 1997Date of Patent: September 28, 1999Assignee: GTE Laboratories IncorporatedInventors: Rajamani Ganesh, Vincent A.

Patent number: 5731699Abstract: Apparatus and method for measuring the radio signal (RF) transmission statistics of a communication channel. The apparatus is arranged to receive and process a wide bandwidth signal from which signal power is measured and from which fading or other such transmission problems can be measured for the wide bandwidth. In parallel with the wide bandwidth receiver there is a narrow bandwidth receiver arranged to receive the same RF signal but to process only a single tone or narrow bandwidth portion of the RF signal. From this narrow bandwidth processing the narrow bandwidth transmission statistical characteristics of the RF transmission channel can be measured simultaneously with the wide bandwidth statistical characteristics. The outputs of the spectrum analyzer are digitized and fed to a computer for storage and for other analysis.Type: GrantFiled: February 12, 1996Date of Patent: March 24, 1998Assignee: GTE Laboratories IncorporatedInventor: Vincent A.

Patent number: 5390043Abstract: In an optical heterodyne communication system for transmission of multiple optical channels at different wavelenths, the optical channels are grouped into blocks for increased utilization of the available bandwidth. The spacing between optical channels within a block is typically equal to or somewhat greater than the channel bandwidth. The spacing between blocks is such that when the optical signal is heterodyned with a local oscillator lightwave, the interference with a selected optical channel from adjacent blocks does not exceed a predetermined level.Type: GrantFiled: February 12, 1991Date of Patent: February 14, 1995Assignee: GTE Laboratories IncorporatedInventor: Vincent A.

Patent number: 5105295Abstract: Apparatus for optical transmission of first and second digital channels. Each digital channel has first and second signal levels. The appparatus has a tunable laser for emitting an optical output at optical frequencies corresponding to current levels. Current responsive to the signal levels of the two channels provides current levels to cause the laser to emit a first optical frequency when the first channel has a second signal level and the second channel has a second signal level, a second optical frequency when the first channel has a first signal level and the second channel has a second signal level, a third optical frequency when the first channel has a first signal level and the second channel has a first signal level, and a fourth optical frequency when the first channel has a second signal level and the second channel has a first signal level. An optical transmission medium is coupled to the output of the laser. A tunable optical filter is coupled to the optical transmission medium.Type: GrantFiled: January 3, 1990Date of Patent: April 14, 1992Assignee: GTE Laboratories IncorporatedInventor: Vincent A.
