Abstract: Techniques are disclosed for systems and methods to provide a staggered multichannel transducer in a ranging system configured to perform remote sensing. The staggered multichannel transducer may extend in a first direction and one or more transducer elements of the array may offset from the other transducer elements in a second direction perpendicular to the first direction. The staggered arrangement of the transducer elements may improve remote sensing performance to produce accurate remote sensing data and/or imagery. The staggered arrangement also may reduce a number of transducer elements used in the transducer array which reduce the cost and complexity of the transducer array. Further, the staggered arrangement in a linear transducer array also allows for two-dimensional beam forming.

Subsequent user input and/or the sensor data may be used to adjust operational modes and/or systems of the remote sensing system.

Abstract: A three-dimensional integrated structure is fabricated by assembling at least two parts together, wherein each part contains at least one metallic line covered with a covering region and having a free side. A cavity is formed in the covering region of each part, that cavity opening onto the metallic line. The two parts are joined together with the free sides facing each other and the cavities in each covering region aligned with each other. The metallic lines are then electrically joined to each other through an electromigration of the metal within at least one of the metallic lines, the electromigrated material filling the aligned cavities.
