Abstract: An assembly, system and method for compensating a crane position offset error based on wheel float by viewing, with an optical sensor located on a trolley on the crane, a target or target shape adjacent a storage rack containing a vertically stored mill roll and determining a positional compensation signal based on a separation or offset of a center of a field of view of the sensor from a center of the target shape. The assembly, system or method compensates for the crane position offset error by moving the crane, as instructed by the positional compensation signal, a distance equal to the separation or offset of the center of the field of view of the sensor from the center of the target.

Abstract: A method for providing thermal protection to a pre-charge unit (PRC) of an electric power conversion system, such as a medium-voltage adjustable-speed drive, with a step-up transformer and a DC link includes the steps of executing a parameter identification block identifying the electrical and thermal parameters of the PRC; of an electric power conversion system executing a current estimation block estimating the current flowing though the PRC's step-up transformer based on a voltage input; executing a thermal level estimation block estimating a thermal level at the PRC's step-up transformer based on the estimated current flowing though the PRC's step-up transformer; executing a protection logic block comparing the estimated thermal level to a pre-determined trip threshold to determine whether a thermal overload has occurred; and outputting a trip signal if the trip threshold has been exceeded.

Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: A system and method enable an external user interface (UI) control for interacting with content in an iFrame web page to be invoked from within the iFrame and displayed outside the iFrame. The iFrame web page detects a predefined user interaction with a UI element in the iFrame web page and sends a UI request message to the host application using cross-domain communication. The host application activates the external UI control in response to receiving the UI request message and displays the external UI control outside of the iFrame element. User input is received with the external UI control and communicated from the host application to the iFrame web page and applied to the UI element.

Abstract: Dynamically overriding a function based on a capability set. A computer system reads a portion of an executable image file. The portion includes a first memory address corresponding to a first callee function implementation. The first memory address was inserted into the portion by a compiler toolchain. Based on extensible metadata included in the executable image file, and based on a capability set that is specific to the computer system, the computer system determines a second memory address corresponding to a second callee function implementation. Before execution of the portion, the computer system modifies the portion to replace the first memory address with the second memory address.

Abstract: Enforcing shadow stack violations at module granularity, rather than at thread or process granularity. An exception is processed during execution of a thread based on code of an application binary, which is enabled for shadow stack enforcement, that calls an external module. The exception results from a mismatch between a return address popped from the thread's call stack and a return address popped from the thread's shadow stack. Processing the exception includes determining that the exception resulted from execution of an instruction in the external module, and determining whether or not the external module is enabled for shadow stack enforcement. Based at least on these determinations, execution of the thread is terminated when the external module is enabled for shadow stack enforcement, or the thread is permitted to continue executing when the external module is not enabled for shadow stack enforcement.

Abstract: A device, system, and method for testing and measuring the grip strength of tongs for a crane system is provided. The device may include a frame body carrying a testing assembly configured to measure the tong grip strength. The system may include the grip strength tester used in conjunction with a crane including an operator tower and a pulley assembly operatively connected to the tongs. The method of use associated with the tong grip strength tester may include the steps of expanding a distance between teeth on the tongs and positioning the teeth adjacent sides of the testing assembly, then closing the tongs thereby clamping teeth to the sides of the testing assembly. Then, the testing assembly measures the compressive force associated with the tongs and registers the compressive force in a computer system to determine whether the grip strength is sufficient to lift a weighted slab of material.

Abstract: Use of pyrolysis oil (commonly referred to as bio-oil, bio-crude or tire oil) in combination with naphtha or liquified petroleum gas (LPG) can be utilized to reduce viscosity, increase API gravity and/or liquify paraffin and/or asphaltene in heavy crude oil at a reduced, overall percentage of naphtha. Terpene, citrus isolates and/or non-ionic surfactants can be added to pyrolysis oil to form an additive. The additive can be combined with naphtha or LPG and added to heavy crude oil to reduce viscosity, increase API gravity, and/or liquify paraffin and/or asphaltene at a reduced, overall percentage of naphtha.
