Electronic device

Abstract

An electronic device comprising a support plate together with a first and a second cover is provided. One or more electrical components are mounted on the support plate. The first cover is located on and connected to a first surface of the support plate. The first cover is configured and positioned to cover and thereby define a first sealed cavity over the, or each, respective component. The second cover is located on and connected to a second, opposing, surface of the support plate. The second cover is configured to define a second sealed cavity and is positioned to, at least partially, overlap a region of the support plate covered by the first cover.

1 . A maritime unmanned vehicle, configured to operate in a surface region of a body of water, comprising:
 a support plate, upon which is mounted an electrical component;   a first cover, located on and connected to a first surface of the support plate, the first cover being configured and positioned to cover and thereby define a first sealed cavity over the, or each, respective component; and   a second cover, located on and connected to a second, opposing, surface of the support plate, the second cover being configured to define a second sealed cavity and positioned to, at least partially, overlap a region of the support plate covered by the first cover;   wherein the support surface comprises routing apertures formed therethrough within the overlap region of the covers to thereby enable passage of cables from the first sealed cavity to the second sealed cavity;   and wherein said support plate substantially provides an endoskeletal structure for said vehicle and is configurable for mounting thereon thrusters and/or actuable control surfaces.   
     
     
         2 . (canceled) 
     
     
         3 . A device according to  claim 1 , wherein the, or each, cover is a complex shape. 
     
     
         4 . A device according to  claim 1 , comprising a third cover, located on and connected to the first surface of the support plate, the third cover being configured to define a third sealed cavity and positioned to, at least partially, overlap a region of the support plate covered by the second cover. 
     
     
         5 . A device according to  claim 1 , wherein the support plate comprises a thermally conductive material upon which the, or each, component is mounted to effect cooling thereof. 
     
     
         6 . A device according to  claim 5 , wherein the support plate additionally comprises a composite material located outside a region upon which the, or each, component is mounted. 
     
     
         7 . A maritime electronic device according to  claim 1 , wherein each sealed cavity comprises a water tight seal between a respective cover and the support plate to inhibit ingress of moisture into the cavity. 
     
     
         8 . A maritime electronic device according to  claim 7 , comprising a skin, located over the, or each, cover and configured to define a “floodable” region of the device. 
     
     
         9 . A littoral unmanned underwater vehicle, comprising a device according to either of  claim 7  or  8 . 
     
     
         10 . A vehicle according to  claim 9 , configured such that it can be launched by two users.
