Abstract: Non-visible objects which differ in their physical properties from their surroundings by association with a variable strength magnetic field may be detected by a suitable array of sensors which can be moved relative to the object in question. By analyzing the signals from the plurality of the sensors in the array, the position of the object can be deduced relative to the array and the array moved to enable a machining guide thereon to be aligned with the non-visible object. The system is of particular value in locating apertures in wing spars when attempting to fix the skin of the wing on to them where it is important to be able to locate the correct point at which to drill a hole through the skin to coincide with the hole in the spar. By defining a magnetic field in the vicinity of the hole to identify the hole magnetically and using an array of magnetic field sensors in a base with an aperture, it is possible to shift the array so that the aperture is precisely aligned with the non-visible hole.

Abstract: A system and method can identify manufactured parts. A user can select a particular manufactured part, which can be out-of-specification. The system can retrieve test data for the selected part and for other manufactured parts. The system can normalize the retrieved test data against historical means and historical standard deviations to form normalized test data. The system can correlate the normalized test data for the selected part against normalized test data for each of the other manufactured parts to form correlation values. The system can display the correlation values with identifiers corresponding to the manufactured parts. Each correlation value can represent a degree of similarity between the selected part and a respective manufactured part. The manufactured parts with the highest correlation values can have the same failure mechanism as the selected part, which can help diagnose why the selected part can be out-of-specification.

The matrix may be about 100 parts by weight of a low viscosity cycloaliphatic epoxy resin with an anhydride curing agent. The thickener may be about 10-20 parts by weight of an additive comprising a clay. The strengthener may be about 5-10 parts by weight of a glass. The soluble medium may be about 20-30 parts by weight of a water-soluble fiber.

Abstract: Disclosed are implementation for revoking and updating a compromised root-of-trust (ROT), including a method comprising determining whether a current validation value, representative of an expected value resulting from application of a validation function to a current certificate, is to be replaced, with the current validation value being stored in a write-restricted non-volatile memory unit of the device. The method also comprises determining at boot time whether a physical presence indicator, configured to be non-actuatable from non-proximate locations, is set to a value indicating that an actuation mechanism (for actuating the physical presence indicator so as to cause content change for the write-restricted memory), has established physical presence with the device, and providing a new validation value in response to determining that the current validation value is to be replaced and that the physical presence indicator indicates that physical presence has been established.

Abstract: An efficient low flow, low head, undershot double acute angle turbine where the flow strikes the blades at 90° without the Betz limit. Blades are set at an acute angle to the axle and the turbine is positioned in the flow at the compliment of the blade angle. There is no lag on downstream blades. There is no turbulence when the idle blade enters the flow. Active blades exhaust to the next blade to extract more energy. Simple adjustments set the flow to the blade tip that will produce the highest rotational speed. It is portable. It can be scaled up for larger applications by adding blades to the axle or using longer blades. It can be made from repurposed materials using hand tools. Hydro installations include in a sluice and on a floating barge. It has been tested successfully in flowing water and wind.
