Abstract: Wear sensors are provided on a drill bit or other rotary cutting tool which is for operation in a subterranean borehole and has a plurality of separate cutters protruding from a support structure towards the material to be cut by the tool. The electrically operated sensing means are located at or coupled to a sensing point within a protrusion from the support structure. This sensing point is located within a protrusion such that attrition of at least one cutter to a partially worn state brings the protrusion into abrasive contact with the material being cut and attrition of the protrusion then exposes the sensing point to the material which is being cut by the tool and thereby brings about a detectable change, which may include damage to the sensor at the sensing point, indicative of wear. The tool includes means to communicate data from the sensing means to the surface.

Abstract: Methods and systems relating to a file distribution scheme in a computer network are disclosed that distributes files in an efficient manner that reduces, among other things, network traffic. In an embodiment of the invention, a method for updating a file is disclosed. In such a method, unique chunks in a first version of a digital file are identified. For a second version of the digital file, chunks that are the same as in the first version are identified. Recompilation information is generated and stored for these identified chunks. Also, for the second version of the digital file, chunks in the second version that are different from chunks in the first version are identified. Recompilation information is generated and stored for these identified chunks. With this information, the second version of the digital file is completely defined and can be efficiently stored.

Abstract: Requests of a computing system may be monitored. A request associated with the application of a policy may be identified and a policy verification routine may be invoked. The policy verification routine may detect whether the policy of the request is more permissive than a reference policy and perform a mitigation routine in response to determining that the policy of the request is more permissive than the reference policy. Propositional logics may be utilized in the evaluation of policies.

Abstract: Security policies may be utilized to grant or deny permissions related to the access of computing resources. Two or more security policies may be compared to determine whether the policies are equivalent, whether one security is more permissive than another, and more. In some cases, it may be possible to identify whether there exists a security permission that is sufficient to determine two security policies lack equivalency. Propositional logics may be utilized in the evaluation of security policies.
