Abstract: A method is disclosed and includes authenticating a first stage boot loader and authenticating a second stage boot loader in response to authentication of the first stage boot loader. The method also includes executing the second stage boot loader in response to authentication of the second stage boot loader. Executing the second stage boot loader includes loading an operating system, a first set of machine-readable instructions, and first configuration information associated with the first set of machine-readable instructions onto a non-transitory computer-readable medium, wherein the first set of machine-readable instructions and the first configuration information are associated with one or more priority partitions. Executing the second stage boot loader includes authenticating the operating system and the first set of machine-readable instructions.

Abstract: The downhole torque limiter and method eliminate damage to downhole components by eliminating excessive torque transmission. The device comprises a housing, compression assemblies, and anti-rotation plates. Inner and outer assemblies of the device are permitted to slip with respect to each other after reaching a settable torque limit which is preferably below the maximum capacity of other downhole components. The device may be positioned in drill strings that comprise a downhole motor and/or drill bit as well as drill strings that do not comprise a downhole motor and/or drill bit. In drill strings comprising a downhole motor and/or drill bit, the device may be positioned below the downhole motor and above the drill bit, adjacent to and above the downhole motor, or above the downhole motor such that at least one drill string joint is positioned between the device and the downhole motor.
