Patent number: 11740278Abstract: An electronic test equipment apparatus includes a power terminal configured to receive power, an interface for a device under test (DUT), at least one power transistor connected in series between the power terminal and the interface for the DUT, and a protection circuit. The protection circuit is configured to: switch on the at least one power transistor, to electrically connect the power terminal to the DUT through the interface as part of a test routine; and subsequently automatically switch off the at least one power transistor after a predetermined delay, to electrically disconnect the power terminal from the DUT regardless of whether the DUT passes or fails the test routine. A voltage clamp circuit for electronic test equipment and corresponding methods of testing devices using such electronic test equipment are also described.Type: GrantFiled: August 2, 2019Date of Patent: August 29, 2023Assignee: Infineon Technologies AGInventors: Kevin Roche, Alfonso Diy, Emanuel-Petre Eni, Josef Niedermeyr, Efren Tarlac

Publication number: 20220170163Abstract: A metal surface treatment method wherein the surface (10) is simultaneously bombarded with a mixture of abrasive particles (4) and dopant particles (6) which are delivered at a velocity in the range of 50-250 m/sec, and thereby depositing the dopant material on the surface. Also provided is an article (8) having a surface treated by such a method.Type: ApplicationFiled: July 9, 2021Publication date: June 2, 2022Applicant: ENBIO LIMITEDInventors: Barry TWOMEY, John O'DONOGHUE, Kevin ROCHE, Liam O'NEILL, Paolo Vincenzo Ercole FIORINI

Publication number: 20170144270Abstract: A method of treating a substrate, the method comprising: delivering substantially simultaneously a first set of particles comprising a dopant and a second set of particles comprising an abrasive from at least one fluid jet to a surface of the substrate, to impregnate the surface of the substrate with the dopant; wherein the dopant comprises a corrosion-inhibiting or adhesion-promoting species, such as to form a corrosion-inhibiting or adhesion-promoting coating at or on the surface of the substrate. Also provided is an article comprising a substrate having a corrosion-inhibiting or adhesion-promoting coating, the said coating comprising particles of a corrosion-inhibiting or adhesion-promoting species that impregnate the surface of the substrate (e.g. as produced by the above method).Type: ApplicationFiled: March 20, 2015Publication date: May 25, 2017Inventors: Barry TWOMEY, Kenneth STANTON, John O'DONOGHUE, Kevin ROCHE, Joseph MOHAN

Publication number: 20100151136Abstract: A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.Type: ApplicationFiled: February 23, 2010Publication date: June 17, 2010Applicant: Z CorporationInventors: Thomas Davidson, Robert A. Philips, Andres T. Hernandes, David B. Russell, Kevin Roche, Walter H. Zengerle, III, Andrew Berlin, Joshua P. Kinsley, Benjamin Daniel Sweet-Block, Darul Kisai
