Patent number: 11115735Abstract: Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.Type: GrantFiled: May 30, 2018Date of Patent: September 7, 2021Assignee: COMMSCOPE TECHNOLOGIES LLCInventors: Olivier Hubert Daniel Yves Rousseaux, Joseph Christopher Coffey, David James Mather, John Charles Chamberlain, Erik J.

Patent number: 8574710Abstract: A composition includes a substrate (a) including a surface and (b) a multi-layer coating of nanowires positioned on at least a portion of the surface. The coating includes three or more laminar layers of nanowires and a bottom layer of nanowires affixed to the surface and a top-most layer of nanowires. A nanowire within a laminar layer is oriented substantially parallel to another nanowire within the same laminar layer. Nanowires within adjacent laminar layers are not substantially parallel to one another. The top-most layer of nanowires has a refractive index of about 5% to about 70% of the refractive index of the bottom layer of nanowires, and the refractive index of the three or more laminar layers of nanowires is decreases by about 10% or more per laminar layer from the bottom layer of nanowires to the top-most layer of nanowires.Type: GrantFiled: October 13, 2009Date of Patent: November 5, 2013Assignee: Nano Terra Inc.Inventors: David Christopher Coffey, Brian T.

Patent number: 7676592Abstract: A scheme by which a network device may be made to locate data signals from a plurality of potential data sources in the context of a network environment having devices that employ autonegotiation over an autonegotiation period. The scheme involves switching an input port on the network device between the various potential data sources on a one-by-one basis. If an idle signal indicating no ensuing autonegotiation period is detected, the switching action is terminated and the input port assignment is maintained for as long as the link is detected. Thereafter, the device returns to the switching state. If an idle signal indicating an ensuing autonegotiation period is detected, the switching action is stopped for a period equal to or longer than the autonegotiation period. Thereafter, if an idle signal is detected, the input port assignment is maintained for as long as the link is detected.Type: GrantFiled: September 24, 2003Date of Patent: March 9, 2010Assignee: ADC Telecommunications, Inc.Inventor: Joseph Christopher Coffey

Publication number: 20050279676Abstract: A fluid filter assembly for a water dispensing faucet includes a housing assembly that is constructed and arranged to connect to a water dispensing faucet, a cover assembly that is threadedly attachable to the housing assembly for defining an interior receiving space therebetween and a replaceable filter cartridge installed into the receiving space and being constructed and arranged for filtering a flow of water before that water is delivered to the dispensing faucet. A plurality of reed switches are utilized that are responsive to changes in magnetic flux in order to provide electronic indications of filter status. Some of these electronic indications include the filter cartridge status in terms of its useful life, when a non-approved filter cartridge is installed, when there is no filter cartridge installed, when there is a water leak within the fluid filter assembly, and when one used filter cartridge has been replaced by a new filter cartridge.Type: ApplicationFiled: June 21, 2004Publication date: December 22, 2005Inventors: Zuhair Izzy, Garry Marty, Kyle McMains, Jeffrey Moore, Christopher Coffey
