An apparatus is provided for analysis of a repair for a structure by identifying component parts of the structure that have common material properties and geometric constraints, and based thereon determining a generic repair component for the component parts that also have the common material properties and the geometric constraints. A set of loads are extracted from a loads model of the undamaged structure and redistributed in a loads redistribution model at a damaged or defective portion of the component part. The set of redistributed loads indicate loading incurred by the generic repair component under an external load. The apparatus then uses the redistributed loads to perform an analysis to determine a margin of safety of the generic repair component and, in instances in which the margin of safety is positive, outputs the material properties and geometric constraints of the generic repair component to a fabrication system for production thereof.

If a margin of safety corresponding to a difference between n and N reaches a minimum acceptable level, then action is taken to increase the margin of safety.

An omnidirectionally illuminated helmet emits light along a substantial portion of the helmet surface. An interior cushion is provided for comfort and safety of the wearer's head, while an outer shell is provided for protection from impacts. This outer shell includes a plurality of transparent displays intermingled with opaque sections or regions throughout the entire surface. An electroluminescent light source substantially covers the interior cushion. The outer shell is then placed upon the electroluminescent light source in a manner that aligns the plurality of transparent displays with the light source so that the transparent displays emit light therefrom. Transparent displays are located on the entire hemispherical constructs of the outer shell, including the sides, back, front, and top, so that light is emitted from virtually the entire helmet and can be seen from any vantage point. The margin of safety provided during dusk or night-time hours when vehicles may be approaching is substantially increased by illuminating the wearer's head from all angles.

Smart instrumentation and monitoring provide primary engine instrumentation for an aircraft. The instrumentation generates real time engine power available data for the entire power regime and flight envelope of the aircraft while engine monitoring functions track, record and output performance usage data, trend data, and flight profile data. Generated data is provided to an aircraft flight manual and mission management module that automatically calculates and generates aircraft operational and performance data needed to safely operate the aircraft. The generated data is selectively displayed on flat-panel cockpit displays and / or electronic kneeboard displays in a graphical format that enhances aircrew situational awareness and permits aircrew members to operate the aircraft with its intended margin of safety.

A performance control technique for a processing system that includes one or more adaptively-clocked processor cores provides improved performance / power characteristics. An outer feedback loop adjusts the power supply voltage(s) provided to the power supply voltage domain(s) powering the core(s), which may be on a per-core basis or include multiple cores per voltage domain. The outer feedback loop operates to ensure that each core is meeting specified performance, while the cores also include an inner feedback loop that adjusts their processor clock or other performance control mechanism to maximize performance under present operating conditions and within a margin of safety. The performance of each core is measured and compared to a target performance. If the target performance is not met for each core in a voltage domain, the voltage is raised for the voltage domain until all cores meet the target performance.

The invention provides a preparation method of a resin composition for a thermosetting aramid bulletproof composite material, and relates to the field of resin modification. The resin composition comprises 25-50% of phenolic resin, 30-60% of polyvinyl butyral solution, 10-25% of a flexibilizer and 8-12% of a reinforcer. In addition, a silicane coupling agent with an addition rate of 2-5% is adopted to improve the compatibility of the resin and fabrics, and improve the adhesion between the resin and the fabrics. Phosphoric acid is used as a thermal stabilizer to improve the weathering resistance of the resin, and is added at an amount of 1-5%. The components are mixed proportionally to prepare a modified phenolic resin system. The modified phenolic resin thus prepared has the advantages of high toughness, moderate bonding strength, excellent anti-aging property and good stability. According to shooting tests, the aramid bulletproof composite material prepared from the resin composition has the characteristics of high bulletproof performance and large margin of safety, and can significantly improve the safety and reliability of fighters.

The present disclosure is concerned with the reduction of an operational security margin of a power system without jeopardizing the safety of the power system or incurring heavy investments. According to the disclosure, a check for basic accuracy or correctness of a conventional State Estimation (SE) procedure allows to increase a level of confidence in the results of the procedure. To this end, an accuracy of the estimated states is verified by comparing the latter with the results (y, y′) of independent phasor measurements performed at selected locations of the power system. Unless a discrepancy is reported by this comparison, the results of the SE can be assumed to be sufficiently accurate, and any conservative or additional security margin intended to compensate for SE uncertainty can be relaxed. Hence, established trustworthiness in the estimated states allows increasing the transmitted power where the estimated states do indicate such a possibility, i.e. in particular in fringe areas and / or transmission corridors between countries, and especially under stressed network conditions.

A nylon or polypropylene cylindrical central braided rope core is wound with an electroluminescent wire to form a pet leash. The electroluminescent wire is powered by a portable power supply attached to the handle of the pet leash causing illumination of the electroluminescent wire continuously or intermittently at a selected blink rate. Alternatively, the wound electroluminescent wire surrounds a cylindrical braided reflective sleeve that covers the central braided rope. The cylindrical braided reflective sleeve reflects incident light back to its source while the electroluminescent illumination is provided. Reflection and illumination of light are omnidirectional. The braided construction of the central core and reflective sleeve, together with the configuration of the electroluminescent wire, resist tensile, twist and torsional forces, enabling reliable emission of omnidirectional illumination and reflectivity. In combination, the omnidirectional illumination and reflectivity, strength and flexibility provide a higher margin of safety for pets and their owners while walking in dimly lit environments where vehicles are encountered.

A compact, substantially planar needlestick prevention safety device has a discoid shield-like portion, divided into an upper and lower half via a living hinge, and a pair of squeezable handles extending laterally therefrom. A central beveled aperture with outwardly extending radial slits accommodates within it a wide range of needle cap sizes. When the handles are squeezed by hand, the upper and lower halves of the disc fold toward each other along the living hinge and impart a variable and easily controllable amount of clamping force at the central aperture, thereby securely gripping the needle cap for uncapping or recapping purposes. The device provides a very high margin of safety during recapping, fits easily in the coat pocket for ease of accessibility, and is reusable and sterilizable by any sterilization method.
