摘要： A method of friction-stir welding, FSW, ajoint J, for example a T joint and/or a lap joint, between a first workpiece W1 and a second workpiece W2, is described. The method comprises: performing a first pass P1 of FSW of the joint J by moving therealong a first tool (10), comprising a first probe (100) rotating in a first rotational direction RD1, in a first movement direction MD1 defining a first line L1, on a first side S1 of the joint J, comprising: inserting the first probe (100) to a first depth D1, thereby providing a first welded region WR1; withdrawing at least partially the first probe (100), thereby providing a first partially welded and/or unwelded region PWUR1; and fully withdrawing the first probe (100), thereby resulting in a first exit hole EXH1; performing a second pass P2 of FSW of the joint J by moving therealong a second tool (20), comprising a second probe (200) rotating in a second rotational direction RD2, in a second movement direction MD2 defining a second line L2, on the first side S1 of the joint J, comprising: inserting the second probe (200) to a second depth D2, thereby providing a second welded region WR2; optionally withdrawing at least partially the second probe (200); and fully withdrawing the second probe 200, thereby resulting in a second exit hole EXH2; wherein the second welded region WR2 includes the first exit hole EXH1; and wherein the second exit hole EXH2 is included in the first welded region WR1.

摘要： An equipment enclosure (1) for electromagnetically isolating an electronic device, the equipment enclosure 1 comprising a conductive housing (3) and a plurality of conductive sheets (5). Each sheet (5) includes an aperture (7). The sheets (5) are stacked in a spaced-apart relationship within the housing (3) thereby defining a plurality of electromagnetically-isolated cavities (9) each within a respective Faraday cage formed by the conductive housing (3) and the conductive sheets (5). The apertures (7) form a channel (11) that extends through the enclosure (1) providing a route for connections between the cavities (9).

摘要： When the tension across the cord's 24 length reaches a predetermined threshold, an activation mechanism within the payload 16 and coupled to one of the cord's 24 ends is actuated in order to activate the payload 16. Activating the payload 16 may include deactivating a SAFU, activating a motor 32 disposed within the housing, or causing flight controls to extend from a housed position. Here, “within the payload 16” may mean part of the activation mechanism is disposed on the outer surface or housing of the payload 16.

摘要： Methods and apparatus for detecting a modulating element of an object in a scene are described in which an element in a scene is illuminated with a modulated light source. A signal is obtained from an optical detector based on light received from the illuminated element. An intermediate frequency signal is detected from the signal obtained from the optical detector, the intermediate frequency signal being related to a frequency of the modulated light source and a frequency of modulation of the element within the scene. The modulating element is detected based on the intermediate frequency signal.
