Abstract: A method comprising: providing an autonomous vehicle (AV) with a first estimated position of a target; directing the AV to travel toward the first estimated position at a constant velocity; receiving echo signals of transmitted sonar signals, the echo signals indicating a range and an azimuth of the target; determining a depth difference of the AV and the target based on the received echo signals, the depth difference being determined based on changes to the range and azimuth of the target over time; and in response to a depth difference existing, re-directing the AV toward a second estimated position of the target generated from the depth difference.

Abstract: A transparency having a bus bar system includes a non-conductive substrate having a major surface. At least one conductive coating is located over at least a portion of the major surface. An electrically conductive adhesive, such as an isotropically conductive tape or film, is located over at least a portion of the conductive coating. A metallic member, such as a metallic foil or metallic braid, is located over the isotropically conductive adhesive.

Abstract: A laminated transparency includes a first ply having a No. 1 surface and a No. 2 surface. A second ply is spaced from the first ply and has a No. 3 surface and a No. 4 surface, with the No. 2 surface facing the No. 3 surface. A polymeric interlayer is positioned between the first and second plies. At least one failure strip is incorporated into the interlayer to provide a predetermined failure orientation for the transparency.

Abstract: A method, composition, and article are disclosed relating to the formation of a hump seal on an aircraft transparency. The method includes applying to the aircraft transparency an adhesive composition having a Part A and a Part B. Part A includes a plasticizer, a cross-linking agent, and an adhesion promoter. Part B includes a moisture resister and an abrasion resister, with the adhesive composition being substantially sulfide free. In one example, the moisture resister includes polybutadiene. In another example, the adhesion promoter includes an epoxy silane.

Abstract: A submergible towed body system carries an acoustic transmission/reception evice under the surface of the water and relays signals between the acoustic transmission/reception device and a surface platform. An elongated support frame has upper and lower horizontal frame sections maintained in a parallel spaced apart relationship by a plurality of vertical frame supports. A float is attached on top of the upper horizontal frame section and a tow point depends from the upper horizontal frame section. Attached to the upper and lower horizontal frame sections is a combination tilt and pan mechanism that allows the acoustic transmission/reception device to pan through a prescribed horizontal angle and tilt through a prescribed vertical angle. Circuitry is mounted between the upper and lower horizontal frame sections and aft of the tilt and pan mechanism for electrically connecting the surface platform to the acoustic transmission/reception device.
