Publication number: 20250000703Abstract: An ophthalmic device comprises an ophthalmic mask having a first side for application or support on the eyeball, and a second side facing away from the first side, a plurality of positioning markers for positioning a light guide on the positioning marker, the mask body being opaque in a planar central area for a light used to treat the eye, an area size of the central area being adapted to an area size of the pupil and iris of an eye to be treated. The positioning markers are formed on the mask body as indentations on the face-sided edge extending from the second side into the mask body. The mask body is transparent to the light in the area of the indentations. A dimension of the indentations is adapted to a dimension of a light guide provided for the punctual application of light.Type: ApplicationFiled: November 18, 2022Publication date: January 2, 2025Inventors: Reinhardt THYZEL, Colin Francis THYZEL

Publication number: 20150381737Abstract: A gateway device is disclosed for use in an internet-of-things environment. The gateway device comprises a sensor interface for interfacing with a plurality of sensors. A first memory unit is provided for storing sensed data received from the sensors. A second memory unit is provided for storing template data associated with the sensors which is generated by the sensor interface. A processing module is configured for generating encoded messages associated with the respective sensors containing the sensed data and the template data. A communication module is operable for communicating the encoded messages to a central server for decoding.Type: ApplicationFiled: June 30, 2014Publication date: December 31, 2015Applicant: DAVRA NETWORKS LIMITEDInventors: Joseph Anthony Quinn, Colin Francis Ryan, Brian Michael McGlynn

Publication number: 20110315251Abstract: An electronically controlled valve includes a travelling member with a sealing member and operable between a closed position in which the sealing member forms a seal with a valve seat, and an open position. The valve further has a decelerating mechanism operable to slow the movement of the armature during closure of the valve. The sealing member and armature are decoupled and thereby moveable relative to each other such that the armature can continue to move and decelerate due to the action of the damping mechanism after the sealing member has impacted the valve seat. The peak deceleration force on the armature is thereby reduced, increasing the lifetime of the valve or the maximum rate at which it can be closed without damage.Type: ApplicationFiled: March 16, 2010Publication date: December 29, 2011Applicant: ARTEMIS INTELLIGENT POWER LIMITEDInventors: William Hugh Salvin Rampen, Uwe Bernhard Pascal Stein, Fergus Robert Mcintyre, Gordon Paul Voller, Colin Francis Souza

Patent number: 7416582Abstract: A cyclic process for the removal of NOx from a NOx containing feed gas, and optionally removal mercury vapour and/or sulfur dioxide is provided. A process is also provided by which an iron chelate absorbent may be thermally regenerated.Type: GrantFiled: August 22, 2005Date of Patent: August 26, 2008Assignee: Cansolv Technologies Inc.Inventors: Leo E. Hakka, Michel A. Ouimet, John Nicolas Sarlis, Colin Francis Ryan

Publication number: 20060127188Abstract: A pier (10) to be driven into a ground surface includes an auger member (11) having a shaft (12) that is rotated in a first direction to drive the auger member into the ground surface, and a compaction member (16) having a sleeve (17) surrounding a portion of the shaft. The compaction member (16) includes a compaction part (18) attached to and extending laterally outwardly of the sleeve (17). A threaded rod (23) engages the shaft (12) and is rotated to cause the compaction member (16) to move down the shaft (12) and compact the soil around the shaft.Type: ApplicationFiled: September 2, 2003Publication date: June 15, 2006Inventor: Colin Francis

Patent number: 6554188Abstract: This invention is for a reader/writer device (terminal) for accessing item-related data in rewritable tags of the “RF-ID” type wherein each tag includes non-volatile memory. In a farm animal application each animal is implanted with an identified tag. From time to time, the terminal can be given a selected security level by reading password-like and individual identity data from a special tag held by an individual. As a result the individual can gain “read” and/or “write” to selected fields in the data record held within the tag. Further information may be added from time to time by empowered individuals. Schemes are enabled for the enhanced management of animals having such tags include accurate descriptors, proving ownership, showing compliance with disease control programmes and withholding periods after possible treatments, traceability of meat products from the shop to the farm, breeding schemes and performance recording.Type: GrantFiled: October 15, 2001Date of Patent: April 29, 2003Assignee: Electronic Data Holdings LimitedInventors: Colin Francis Johnson, Owen Richard St George, Murray Greenman, Gordon Douglas Irving, Christopher Lee Sommerville

Patent number: 6424314Abstract: A support for a deployable reflector for use on a modular satellite antenna assembly is constructed of an elongated boom supported at both ends by a pair of two axis actuators. The boom is attached at its inboard end to the satellite structure in close proximity to the point of attachment of the associated signal feed assembly to minimize the differential thermal stress throughout the antenna assembly.Type: GrantFiled: May 16, 2001Date of Patent: July 23, 2002Assignee: Space Systems/Loral, Inc.Inventors: Varouj G. Baghdasarian, Colin Francis

Patent number: 6080927Abstract: A solar concentrator for producing usable power as heat and/or electricity uses a self-steering heliostat 1502 to concentrate solar radiation 1509 onto an absorbing surface such as, or including, a solar cell array 1511 capable of absorbing power from the radiation, meanwhile removing heat (such as from long-wave infra-red radiation or resistive losses) from the surface with fluid heat transfer means 1503, 1504, then making effective use of that low-grade heat. Thus the solar cell array is kept relatively cool and a larger proportion of the solar energy incident on the reflector unit is used. The invention uses electricity 1506 from the solar cells to move a transporting fluid through a heat exchanger 1504. Excess electricity may be available for local storage or use 1510, or feeding 1512 to the power distribution grid. Applications include warming swimming pools 1501, heating hot-water supplies using excess electricity, or warming, lighting and ventilating open spaces.Type: GrantFiled: February 28, 1997Date of Patent: June 27, 2000Inventor: Colin Francis Johnson
