Patent number: 10352880Abstract: This disclosure presents systems for x-ray microscopy using an array of micro-beams having a micro- or nano-scale beam intensity profile to provide selective illumination of micro- or nano-scale regions of an object. An array detector is positioned such that each pixel of the detector only detects x-rays corresponding to a single micro- or nano-beam. This allows the signal arising from each x-ray detector pixel to be identified with the specific, limited micro- or nano-scale region illuminated, allowing sampled transmission image of the object at a micro- or nano-scale to be generated while using a detector with pixels having a larger size and scale. Detectors with higher quantum efficiency may therefore be used, since the lateral resolution is provided solely by the dimensions of the micro- or nano-beams. The micro- or nano-scale beams may be generated using an arrayed x-ray source or a set of Talbot interference fringes.Type: GrantFiled: May 26, 2017Date of Patent: July 16, 2019Assignee: Sigray, Inc.Inventors: Wenbing Yun, Sylvia Jia Yun Lewis, Janos Kirz, Srivatsan Seshadri, Alan Francis Lyon, David Vine

Publication number: 20070142526Abstract: Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance and corrosion protection strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. The rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.Type: ApplicationFiled: March 1, 2007Publication date: June 21, 2007Applicant: THE P.

Publication number: 20070087116Abstract: Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance, corrosion protection and bond strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. Resulting formulations benefit from the fact anti-settling agents need not be incorporated into the resin to keep the inorganic material suspended. Also, the rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.Type: ApplicationFiled: October 18, 2005Publication date: April 19, 2007Inventors: Ronald Goetter, David Vines

Publication number: 20060136394Abstract: Disclosed is a method, apparatus and computer program for producing input to a transformation engine. A request is received to transform some data. It is determined whether the data is stored in a form permitting said data to be lazily constructed into a graph structure upon request by a client. If the data is stored is such a form, then it is determined whether to convert the stored data into a graph structure from which structure input to the transformation engine can be produced. In the affirmative the data is converted and input to the transformation engine is produced from this graph structure. Otherwise input to the transformation engine can be produced directly from the stored data.Type: ApplicationFiled: October 24, 2005Publication date: June 22, 2006Inventors: Kelvin Goodson, David Vines

Publication number: 20060126657Abstract: Provided are a method, system, and program for generating asynchronous interfaces and methods from synchronous interfaces and methods receiving a synchronous interface to a target component having a synchronous method used by a client component to synchronously invoke the target component. An asynchronous interface is generated for the synchronous interface of the target component. An asynchronous method is generated for the generated asynchronous interface having arguments to invoke the target component, wherein the client calls the generated asynchronous method to cause an asynchronous execution of the synchronous method.Type: ApplicationFiled: December 15, 2004Publication date: June 15, 2006Inventors: Michael Beisiegel, Jean-Sebastien Delfino, Martin Nally, Peter Niblett, David Vines

Publication number: 20050222946Abstract: A data processing method, apparatus, computer program product, and service for assuring timely execution of compensation for non-transactional work which is carried out in a transaction under which a data item is processed. A lock is taken before the data item is processed and, in the event the transaction fails, the same lock is also obtained before the data item is re-processed. As a result, re-processing of the data item is held until the lock obtained by the failed transaction is released and this is only done once compensation of non-transactional work is complete. Thus, compensation completes before the message is re-processed.Type: ApplicationFiled: April 5, 2005Publication date: October 6, 2005Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Alexandra Mulholland, Ian Robinson, David Vines

Patent number: 4901275Abstract: A unit for providing an interface between analog input signals and a digital data processing system bus includes a plurality of analog input channels, sample-and-hold circuits, and an analog-to-digital converter. An optical isolation circuit couples the output of the analog-to-digital converter to a dual-port RAM. The gain of each analog input channel is programmable, as is the address of each input channel in the RAM. Thus the channels can be read in any desired order, and different input voltage ranges can be programmed for each channel. The RAM can be read by an external data processing system via a digital system bus.Type: GrantFiled: September 4, 1987Date of Patent: February 13, 1990Assignee: Burr-Brown LimitedInventors: Ian Hardie, David Vine
