Patent number: 11532934Abstract: Digital isolator devices, and many other devices, have a maximum device junction temperature, which, if exceeded, may cause device failure and the integrity of the isolation is no longer guaranteed. The use of an electronic fuse, eFuse, arranged in series with the digital isolator, provides a protection scheme for the digital isolator in which current is limited by the eFuse when it is determined that the supply current of the digital isolator exceeds a predetermined threshold that would the cause junction temperature to increase above an absolute maximum rating. As such, the integrity of the digital isolator is preserved in the event of a system fault.Type: GrantFiled: November 29, 2018Date of Patent: December 20, 2022Assignee: Analog Devices International Unlimited CompanyInventors: Paul O'Sullivan, Maurice O'Brien, Donal G. O'Sullivan, Stefan Hacker, Conal Watterson

Patent number: 10714923Abstract: In electronic systems, the downstream circuitry may be damaged by overcurrent and overvoltage events. Therefore, there is provided a dual protection device for protecting electrical components in electronic systems. The protection device includes a mechanical fuse in conjunction with an electronic fuse, eFuse, the two components connected in series, together protecting against overcurrent events on two levels. The mechanical fuse provides high overcurrent protection, realising fast and reliable protection at high overcurrent events, and the electronic fuse provides low overcurrent protection, realising accurate and resettable protection for low overcurrent events.Type: GrantFiled: November 29, 2018Date of Patent: July 14, 2020Assignee: Analog Devices Internatianal Unlimited CompanyInventors: Paul O'Sullivan, Maurice O'Brien, Donal G.

Publication number: 20120240497Abstract: A reinforcing structure is described for use in supporting a floor at a junction thereof with a structural column. The structure has several generally elongate, preassembled frame structures, each frame structure are disposed in rows parallel to one another. The frame structures incorporate the main top and bottom reinforcement bars for the reinforced floor with integral shear connectors forming part of the frame structures and the shear connectors tying the top and bottom reinforcement together. Transverse internal reinforcing bars are disposed parallel to one another and connected across the top or bottom reinforcing bars of each frame structure to connect the preassembled frame structures into a cagework of spaced-apart, rigidly connected frame structures.Type: ApplicationFiled: April 26, 2010Publication date: September 27, 2012Inventors: Maurice O'Brien, Anne O'Brien

Publication number: 20060055501Abstract: An electronic device is manufactured using printed circuit board manufacturing processes. In particular, a laminar device comprises a first metal layer, a second metal layer, at least one layer of device, material sandwiched between the first and second metal layers. A first layer of insulating material substantially covers the first metal layer. A third metal layer is provided on the first layer of insulating material. This third metal layer is divided to provide a first terminal and a second terminal. The first terminal is electrically connected to the first metal layer by a conductive interconnect formed through said first layer of insulating material, and the second terminal is electrically connected to said second metal layer by a conductive path comprising an insulated conductive channel which passes through and is insulated from said first metal layer and said at least one layer of device material.Type: ApplicationFiled: March 14, 2003Publication date: March 16, 2006Applicant: BOURNS., INCInventors: Ray Burke, Maurice O'Brien, Poting Lan, Stelar Chu

Publication number: 20060055500Abstract: The present invention relates to encapsulated or insulated devices. In certain environments and applications, it is necessary to protect devices from external agents. The present invention achieves this by providing a device comprising a segment of insulating material having an aperture defined therein. An element of active, for example positive temperature coefficient (PTC), material is received within the defined aperture. The element is substantially covered by a first metal layer on one side and a second metal layer on the opposing side. A first layer of insulating material substantially covers the first metal layer and a second layer of insulating material substantially covers the second layer of metal. A first terminal provides an external electrical connection to the first metal layer and a second terminal provides an external electrical connection to the second metal layer.Type: ApplicationFiled: January 24, 2003Publication date: March 16, 2006Applicant: BOURNS, INCInventors: Ray Burke, Maurice O'Brien, Brian Ahearne, John Kelly

Publication number: 20030066739Abstract: A controller that provides tactile feedback to an operator comprises a base having force-sensing elements disposed thereon, the base defining a sensing plane having first and second orthogonal axes therein, and a force-transmitting member orthogonally disposed with respect to the base, the force-transmitting member defining a third axis mutually orthogonal with the first and second axes. The force transmitting member moves at least along the third axis in response to an applied force, both to generate an electrically discernible indication and to provide tactile feedback to an operator.Type: ApplicationFiled: July 2, 2001Publication date: April 10, 2003Inventors: Roger D. Rickenbach, Cathal Sheehan, Steven Archibald, Malcolm R. Harvey, Padraig Keane, Tracy William Lay, Maurice O'Brien, Alexy Yessayan
