Abstract: A database stores a document as a plurality of encrypted records, where each record is indicative of an incremental change to the state of the document, and encrypted using a document key. The document key is stored with encryption decryptable using a group key, and the group key is stored with encryption decryptable using a first access key. In response to a request to rotate from the first access key to a second access key, the database decrypts the group key using the first access key, a stores a group key re-encrypted with the second access key.

Abstract: A system for facilitating a medical procedure includes an access device that is configured to provide distance information regarding anatomical structures as the access device is driven to a target anatomical site. For instance, the access device can have either or both of a camera and neuromonitoring electrodes. The camera can send real-time images of the anatomical structures as the access device is driven toward the target anatomical site. The electrodes can emit an electrical current to identify a distance from nerve structure. A visual display can include the anatomical structure identified to the operator to assist in guiding the access device to the target anatomical site.

Abstract: Systems and methods are described for indexing related documents to provide more robust search functionality within an index. In one aspect, a first document, such as a comment or status update associated with a second document or ticket item, may be obtained. As a result of the first document including first data that is linked to second data of the second document, an instance of the second document may be modified to include at least a portion of the first data. An index, which indexes a corpus of documents, such as ticket items, may be updated to include the modified second document, such that the first data is associated with the modified second document in the index. Responsive to a query for the first data in the index, the modified second document and any included first data may be returned.

Abstract: A method for manufacturing a botanically-derived composition includes mixing a cooling agent with a plant causing biomass particles to be removed from the plant. The method further includes creating a suspension comprising the biomass particles. The method further includes removing the biomass particles from the suspension. The method further includes drying the biomass particles to form the botanically-derived composition.

Abstract: Method and system for multi-stage well treatment wherein an isolating device is tethered with a distributed measurement cable during the treatment of one or more stages. The cable having a cable core including an optical fiber conductor.

Abstract: A method of re-treating a well with pre-existing fractures which includes: displacing a tool in a well, leaking off motive fluid to an open fracture zone passed by the tool to diminish the rate of displacement, and locating the open fracture zone above the tool.

Abstract: Method and system for multi-stage well treatment wherein an isolating device is tethered with a distributed measurement cable during the treatment of one or more stages. The cable having a cable core including an optical fiber conductor.

Abstract: A turbine blade assembly that is able to be driven by the wind, the turbine blade assembly comprising a hub, a multiplicity of hub blades attached to and extending outwardly from the hub, a first cowl attached to an end of the hub blades, wherein the first cowl is at an angle of between 9 and 15 degrees with respect to a central axis of rotation of the hub.

Abstract: A shower drain compression ring nut tightening tool includes two vertical legs for engagement into the grooves of the internal brass compression ring nut over the drain pipe inside the no-caulk shower drain body. The tool also includes a T handle connected to the body and legs to rotate the tool and tighten the ring nut in a no-caulk shower drain, even when the drain pipe is high or crooked.

Abstract: Electronic information management includes techniques for developing and applying database security. In certain implementations, database access statements issued for applications in use are analyzed. Analyzing issued database access statements may include capturing the database access statements, normalizing the database access statements, and eliminating redundancies from the database access statements. A standardized set of issued database access statements may result from the analysis procedure. From the analyzed database access statements, the items accessed and types of access may be determined for an application, and a set of permissions may be determined from the determined items accessed and types of access for the application. A role associated with the application may be developed based on the permissions for the application. The role may be used to allow a user database access when associated with the application.

Abstract: A component shim 310 is used with printed circuit boards 306 and heat spreaders 314, for example, where each of the printed circuit board 300 and heat spreader 314 has a surface 304, 312 that are in different spaced apart planes. A component 300 has one lead attached to the surface 304 of the printed circuit board 306. The component shim 310 has a conductive section 320 with an upper attachment layer 326 and a lower attachment layer 332 secured to opposed sides 322, 324 of the conductive section 320. The upper attachment layer 326 is secured to a bottom 308 of the component 300 and the lower attachment layer 332 is secured to a surface 312 of the heat spreader 314. The total thickness of the conductive section 320 and upper and lower attachment layers 326, 332 of the component shim 310 is substantially equal to a distance from the bottom 308 of the component 300 to the surface 312 of the heat spreader 314.
