Abstract: The invention discloses an integrated detection method of electromagnetic searching, locating and tracking for subsea cables. After being launched into water, the cable-tracking AUV carries out primary Z-shaped reciprocating sailing to search the electromagnetic signal of the target subsea cable, when the electromagnetic signal reaches a preset threshold value, the AUV executes the cable-tracking detection. In the tracking process, if the target electromagnetic signal intensity is lower than the preset threshold, it is determined that subsea cable tracking is lost. At this time, the secondary Z-shaped cable-researching route planning and tracking are performed based on the lost point. In the process that the AUV autonomously tracks and detects the subsea cable, relative locating between AUV and subsea cable is performed based on the electromagnetic signal radiated by the subsea cable, and autonomous tracking control under the guidance of the electromagnetic locating signal is performed.

Abstract: Technologies for a flexible three-dimensional power plane in a chassis are disclosed. In one embodiment, a flexible ribbon cable is laid along a circuit board tray. The flexible ribbon cable is secured to the tray using power bosses. The power bosses connect to one or more conductors on the ribbon cable. When the circuit board is mounted on the circuit board tray, the power bosses extend through holes in the circuit board and mate with power clips on the surface of the circuit board tray. The ribbon cable, power bosses, and power clips can distribute power to various locations on the circuit board, without requiring large traces that take up space on the circuit board.

Abstract: A graph refactorization method is provided, and relate to the field of communication technologies, to implement parallel graph processing with load balancing, low communication costs, and short execution time. The method includes: A first machine selects a first vertex from a local vertex set of a subgraph (S801).

If the degree of the first vertex is greater than or equal to a second preset threshold, the first machine copies the first vertex to obtain N sub-vertices, and divides edges of the first vertex in the subgraph of the first machine into N parts to respectively connect to the N sub-vertices (S803).

Abstract: Described herein is a lower parasitic multi-turn MRI phased array coil wherein the geometry is substantially identical between the coil turns. The potential of every corresponding point between the turns of the coil is also substantially equal, for example by using capacitors of substantially equal value and/or using substantially equal lengths of copper trace between breaks. As a result of this arrangement, the potential between coil turns is substantially equal, for example, with substantially equal capacitor value and substantially equal break point on conductor trace. This in turn reduces parasitics between turns because the geometry of each turn of the coil is substantially identical. The lower parasitic multi-turn MRI phased array coil is suitable for use with wired or wireless phased array coils, and is particularly well suited for use with lower field MRI systems.
