  • Patent number: 10242018
    Abstract: A computer-implemented method includes monitoring page allocations in a file system that includes encrypted files, determining if a page allocation request corresponds to an encrypted file, and balancing encrypted page allocations across a plurality of virtual memory pools in response to determining that the page allocation request corresponds to an encrypted file. In some embodiments, balancing encrypted page allocations across the plurality of virtual memory pools comprises determining a virtual memory pool having a lowest encrypted page count and allocating a page from the virtual memory pool having the lowest encrypted page count. A corresponding computer program product and computer system are also disclosed herein.

  • Publication number: 20180360602
    Abstract: The invention relates to prosthetic heart valves comprising a stent frame with valve support disposed or inverted at least partially within the stent frame, wherein the valve support is at least partially within the interior of the stent frame. The inverted configuration comprises a maximum number of layers of material in cross section where the stent frame and valve support overlap. The maximum number of cross-sectional layers of material structure may be reduced to, e.g., two layers of material to reduce outer diameter during delivery by everting the valve portion to a position located outside of the stent portion, followed by inverted reconfiguration back to the inverted anchoring structure after delivery from the lumen of the delivery catheter to the heart chamber.

  • Publication number: 20180276155
    Abstract: A system and computer program product are provided for optimized timer placement. A request to apply a new timer in a computer system is received and an interrupt time for the new timer is extracted from the new timer. A timer list is accessed for each processor in the system responsive to the received request. A range for placement of the new timer is established with respect to each of the accessed timer lists. A timer expiry delay is calculated between proximal processor interrupts and the extracted interrupt time based on the established range placement. Proximity of the extracted interrupt time within the existing processor interrupts is determined and one of the processors is selected based on the calculation and the determined proximity. The new timer is placed on the selected processor.

  • Publication number: 20180256329
    Abstract: Devices and methods for supplementing and/or replacing native cardiac valve functionality, e.g., the mitral valve with a single prosthetic leaflet. An exemplary device is directed to dysfunctional mitral valves. In some cases, the entire device, including the single prosthetic leaflet, will be arranged entirely above the dysfunctional mitral valves and, therefore, disposed entirely within the left atrium. In other cases, the valve support and/or single prosthetic leaflet may extend a distance into the annulus between the left atrium and left ventricle. In some cases, the device will not physically interact with the native leaflets. In other cases, the device may physically interact with the native leaflets.

  • Publication number: 20180113645
    Abstract: A method for transferring memory pages to a first and a second page repository identifies pages in a memory sharing operation for transfer to a first page repository and pages in a memory migration operation for transfer to a second page repository. Pages in the memory migration operation may be prepared for transfer prior to transfer of the pages in the memory sharing operation. Transferring pages in the migration operation may remove the need to transfer pages in the memory sharing operation.

  • Publication number: 20180060494
    Abstract: Mechanisms are provided for implementing a patient health management system. The mechanisms analyze a patient electronic medical record (EMR) for an identified patient to identify a medical condition associated with the patient and identify, based on the results of the analysis, one or more exogenous data parameters associated with the medical condition. The exogenous data parameters are parameters specifying conditions outside the patient's body that affect the health of the patient with regard to the medical condition. The mechanisms retrieve exogenous data, corresponding to the exogenous data parameters, from one or more exogenous data sources and generate a health management plan for the patient based on the exogenous data. The health management plan comprises actions to be performed or not performed by the patient to thereby minimize effects of exogenous conditions, corresponding to the exogenous data parameters, on the health of the patient with regard to the medical condition.

  • Patent number: 9904473
    Abstract: A page type may be identified for each of a plurality of memory pages, the page type corresponding to a particular process that accesses a particular memory page of the plurality of memory pages. The plurality of memory pages may each respectively include duplicate data. The duplicate data may be a same set of data values. Each of the plurality of respective memory pages may be ranked as candidates to deduplicate the set of data values to. The ranking may be based on at least the page type. In response to identifying the first processor and identifying a first memory device, the duplicate data may be deduplicated from the plurality of memory pages to a highest ranked memory page. The deduplication may correspond to coalescing the duplicate data to the highest ranked memory page.

  • Patent number: 9886398
    Abstract: A physical address of a page may be identified. A first process that implements copy-on-read techniques for the page may be detected. A determination may be made that the first process is not expected to write to the page. In response to that determination, a different logical address may be established for the first process for the page from the logical address of a second process for the page, but the two logical addresses may be mapped to the same physical page.
