Patent number: 7459222Abstract: A magnetoresistive medium (1) includes a substrate (2) which has been treated to provide a miscut vicinal surface (3) in the form of terraces (4) and steps (5) of atomic and nanometer scale. There are discrete separated spacer nanowires (7) provided by an intermediate partial spacer film on each terrace (4) against each step (5). A further main film (11) provides main nanowires (10(a), 10(b)). A thin protective layer (15) covers the main nanowires (10(a), 10(b)) which form two separate subsets of main nanowires with different exchange interaction with the substrate and thus a different response to an external magnetic field. In use, when an external magnetic field (H) is applied the response of the main nanowires (10(a), 10(b)) changes as the exchange coupling with the substrate (2) varies and the magnetisation on the main nanowires (10(a), 10(b)) change. This is shown by the arrows while prior to the application of the external magnetic field, they might, for example, be aligned.Type: GrantFiled: March 14, 2005Date of Patent: December 2, 2008Assignee: Provost Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth Near DublinInventors: Igor Shvets, Sunil Kumar Arora, Sumesh Sofin Ramakrishna Pilli

Patent number: 7438858Abstract: A dispensing assembly for liquid droplets that includes a dispenser connected to a liquid carrying pipe which in turn is connected to a source of pressurized liquid. The dispenser has an elongated body member having a main bore connected to the liquid carrying pipe. At the other end, the main bore has a valve seat that is connected to a nozzle having a nozzle bore terminating in a dispensing tip. An elongated valve boss of ferromagnetic material covered with a soft polymer is mounted in the main bore and has a cross-sectional area less than that of the main bore.

Publication number: 20060202292Abstract: A magnetoresistive medium (1) comprises a substrate (2) which has been treated to provide a miscut vicinal surface (3) in the form of terraces (4(a), 4(b)) and steps (5) of atomic and nanometer scale. A further upper film (11) provides upper nanowires (10(a), 10(b)). A thin protective layer (15) covers the upper nanowires (10(a), 10(b)) which form two separate subsets of upper nanowires with different exchange interaction with the substrate and thus a different response to an external magnetic field. The substrate (2) is so chosen that the width of the terraces 4(a) and 4(b) are significantly non-uniform. This leads to a different response depending on which terrace (4(a) or 4(b)) the upper film 11 overlies. It can utilise, for example, step-induced magnetic anisotropy between the upper nanowires (10(a), 10(b)) and the substrate (2).Type: ApplicationFiled: March 14, 2005Publication date: September 14, 2006Applicant: The Provost Fellows and Scholars of the College of The Holy and Undivided Trinity of Queen ElizabethInventors: Igor Shvets, Sunil Arora, Sumesh Sofin Ramakrishna Pillai

Patent number: 6940883Abstract: A laser diode (1) for outputting light of a single mode comprises a substrate layer (5), a cladding layer (6) and a compound light propagating layer (7) comprising first, second, third and fourth layers (9 to 12). A wave guiding region (15) of refractive index lower than its adjacent regions is defined by the third layer (11) by two quantum wells (16) positioned at the anti-node of light of a single mode which is propagating in the third layer (11) for propagating and amplifying the single mode light. A central ridge (17) locates the wave guiding region transversely of the direction of light propagation. The wave guiding region (15) can also be defined by shaping the top cladding layer (6) by forming an elongated central channel through the central ridge (17).Type: GrantFiled: March 28, 2001Date of Patent: September 6, 2005Assignee: The Provost, Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth, Near DublinInventors: James Christopher O'Gorman, Frederick Paul Logue

Patent number: 6805841Abstract: A liquid outlet link assembly is provided for liquid delivery output rates below 10 &mgr;l per minute so as to smooth out the flow from a positive displacement pump which has an immediate step pumping rate which is relatively substantially larger than the delivery rate required through the liquid outlet means. Essentially, this liquid link assembly has a bubble of air or some other pressure activated expansion means which initially contracts on the step pump such as a syringe pump operation and then gradually expands over time, allowing a steady output rate through the link assembly.Type: GrantFiled: May 9, 2001Date of Patent: October 19, 2004Assignee: The Provost Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth Near DublinInventors: Igor Shvets, Dmitri Kashanin, Vivienne Williams

Patent number: 6804272Abstract: A semiconductor self-pulsating laser diode (1) comprises a wave guiding layer (2) sandwiched between lower and upper cladding layers (4, 5). A current blocking layer (8) defining a slot (10) through which pumping current is directed through the laser diode between upper and lower contact plates (5, 6) defines an active wave guiding region (15). The current blocking layer (8) is shaped by the formation of longitudinally extending recesses (12) for defining the active wave guiding region (15) such that a central pulse light generating region (17) is formed surrounded by an outer light propagating region (18). As the laser diode is continuously pumped, an effective step change in refractive index between the wave guiding layer (2) and the outer light propagating region (18) is formed, and the carrier density and refractive index profiles across the active wave guiding region (15) vary as each light pulse cycle progresses.Type: GrantFiled: March 14, 2003Date of Patent: October 12, 2004Assignee: The Provost, Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth Near DublinInventors: James Christopher O'Gorman, Paul McEvoy, Stephen Anthony Lynch, Pascal Michel Landais
