Abstract: In various embodiments of the present invention, a virtual monitor can arrange to properly emulate execution of a cover instruction by operating-system code, or other code assuming to run at highest privilege level, by monitoring a window of instruction execution in which a cover instruction may be executed. Upon occurrence of an interruption, the virtual monitor may configure performance monitoring by the IA-64 processor to count the number of times a cover instruction is executed.

Abstract: Embodiments of the present invention provide full benefit of the cover instruction provided by the Intel IA-64 architecture to code running at less than highest privilege level. In one embodiment of the present invention, prior to execution of a cover instruction by non-privileged code, the code obtains and stores the contents of the current-frame-marker register in memory. Then, the code executes a cover instruction to obtain a new, empty register stack frame and to relegate the registers of previously allocated stack frames to the dirty-register status. Subsequently, the processor state represented by the register values of the stack frame that was current when the cover instruction was executed can be recovered by first executing another cover instruction, computing a previous-frame-marker-register value and placing the computed value into the previous-frame-marker register, executing a first branch (br.

Abstract: In various embodiments of the present invention, debugging and program-behavior-analysis software can reconstruct register-based processor states for nested routine calls from the backing-store memory employed by a modern processor, and by processors of similar architectures, to automatically spill and restore register values via a register stack engine. Sufficient information resides in the backing-store memory to reconstruct the stack frames for all nested routines. However, reconstructing the stack frames from the backing-store memory depends on identifying stored register vales in the backing-store memory containing saved values of the previous-frame-marker application register. Various embodiments of the present invention employ a set of heuristic tests to evaluate stored values in the backing-store memory in order to identify those values corresponding to the stored contents of the previous-frame-marker application register.

Abstract: An ammunition cartridge includes: a basewad disposed within a tube proximate the aft end of the tube; a projectile wad disposed within the tube proximate a fore end of the tube; a propellant charge disposed within a chamber formed between the projectile wad and the basewad; and a projectile disposed within the tube between a forward facing surface of the projectile wad and the fore end of the tube. The aft end of the projectile wad has a powder cup skirt formed thereon, and a chamfer is formed around an outer perimeter of a lip of the powder cup skirt. The chamfer allows the powder cup skirt to be slidably received within a skirt of the basewad to form the chamber. The chamfer provides a clearance at the powder cup skirt lip, which helps to insure undisturbed entry into the mouth of the basewad skirt.

Abstract: A plastic, cup-shaped, multi-petal sabot housing a sub-caliber projectile for use such as in shotgun cartridges. The sabot engages the rifling of the shotgun barrel and transfers the spin to the projectile. A reinforcement disk is advantageously at least partially embedded in a sabot base and has a central aperture and a plurality of additional apertures. Sabot base material extends through the additional apertures. Advantageously, in its relaxed condition, each sabot petal includes a protrusion from its inboard surface for engaging a projectile ogive. The protrusion and its contact area with the projectile are fractions of the local petal width.

Abstract: A device representing a simple means of multiplying the functionality of wiring in point to point control circuits such that fault tolerant, fault reporting circuits can be constructed with less wire. The circuit can employ the wiring on a continuous basis by the use of AC and a series arrangement that may combine sensors and command loads on the same single wire loop. A bi-directional current detector with switchable impedance over each polarity can form the device. The detector may be equipped with an electrically isolated man-machine interface that communicates with light to achieve input-output functions. Command functions may be issued by changing the current level within the circuit over each polarity of current flow to series mounted remote loads that are polarized with diodes. The whole circuit can be in triplicate for high reliability and fault tolerance and use a common return wire.

Abstract: In various embodiments of the present invention, execution-state transitions occur in a first portion of a system, and a cumulative execution state for each process is maintained by a second portion of the system so that, when a second-portion routine is called, the second-portion routine can determine whether or not the current execution state is suitable for execution of the second-portion routine. In various embodiments, a callpoint log, allocated and maintained for each process, stores the cumulative execution state for the process. In one embodiment, the first portion is an operating system, and the second portion is a secure kernel, with the cumulative execution state used by the secure kernel to prevent unauthorized access by erroneously or maliciously invoked operating-system routines to secure kernel routines. In another embodiment, the cumulative execution state is used as a debugging tool by the second-portion routines to catch errors in the implementation of the first-portion routines.

Abstract: A network operational parameter as experienced by network operational traffic is measured by selecting a packet traversing a first monitoring point in a network in accordance with capability in a data structure definition of the packet for having additional information incorporated in the packet. Predetermined information for measuring at least one network operational parameter is incorporated in the selected packet in accordance with its data structure definition, and the packet is forwarded towards its destination in accordance with addressing information in the packet. The packet is again selected while traversing a second monitoring point in the network in accordance with presence of the predetermined information, which is observed and used to implement a measurement of the network operational parameter in accordance with the observed information. The invention may be implemented by using extension headers in networks conforming to IPv6.

Abstract: A controller (10) senses via one or more sensors (12) parameters that correspond to likely cognitive loading for the driver of a vehicle. Based upon a sense of this cognitive loading, the controller (10) selects a particular user interface mode from amongst a plurality of user interface modes when receiving a message via a wireless unit (11) intended for the driver of the vehicle. In general, the selected user interface will present a corresponding cognitive challenge that is reasonable in view of the present cognitive load being experienced by the driver. In one embodiment, the sensor information can be used to also estimate the likely duration of present cognitive loading. This window-of-opportunity information is then additionally used to select a particular user interface option.
