STAPLE CARTRIDGE

A surgical stapling apparatus is disclosed which comprises a tissue stop configured to inhibit tissue from flowing out of the distal end of the stapling instrument as the tissue is being stapled and/or incised. Also disclosed is a surgical stapling apparatus comprising one or more interruptions, or absent staple cavities, in the rows of staple cavities defined therein. Also disclosed is a surgical stapling apparatus comprising a channel configured to receive tissue and/or another surgical instrument therein. In at least one instance, such a stapling apparatus could comprise staple cavities on one side of a longitudinal knife slot and no staple cavities on the other side of the knife slot. Further disclosed are methods for using the surgical stapling devices disclosed herein.

Tiered storage optimization and migration

Systems, methods, and computer program products for automating the management of a tiered storage system, which improves the service life and costs of the flash-based storage devices that comprise the storage system. The systems, methods and program products utilize time series learning models to predict the write frequency of each data block for the next cycle of time. Using the write frequency predictions, management of the tiered flash-based storage system can automatically organize and migrate stored data based on storage costs, migration costs and frequency in which the data is accessed. Data that is more frequently accessed and updated is migrated to high-end flash-based storage devices, which are able to endure a greater number of program/erase cycles, while less frequently accessed data is migrated to less expensive, low-end flash-based storage devices, that have a lower maximum number program/erase cycles.

HYDRAULIC FRACTURING PUMP SYSTEM

A system for fracturing a subsurface formation may comprise a transport unit with hydraulic legs, an electric motor mounted on the transport unit, a fracking pump mounted on the transport unit and configured to be powered by the electric motor, and an oil tank mounted on the transport unit such that the motor and the fracking pump are above the oil tank.

The bonded structure can include a protective element directly bonded to the semiconductor element without an adhesive along a bonding interface. The protective element can include an obstructive material disposed over the active circuitry and a second bonding layer on the obstructive material. The second bonding layer can be directly bonded to the first bonding layer without an adhesive. The obstructive material can be configured to obstruct external access to the active circuitry.

Computer-implemented privacy engineering system and method

A system allows the identification and protection of sensitive data in a multiple ways, which can be combined for different workflows, data situations or use cases. The system scans datasets to identify sensitive data or identifying datasets, and to enable the anonymisation of sensitive or identifying datasets by processing that data to produce a safe copy. Furthermore, the system prevents access to a raw dataset. The system enables privacy preserving aggregate queries and computations. The system uses differentially private algorithms to reduce or prevent the risk of identification or disclosure of sensitive information. The system scales to big data and is implemented in a way that supports parallel execution on a distributed compute cluster.
