Abstract

An autonomous watercraft with a waterproof container that houses a satellite communication terminal. The waterproof container includes a first shell mounted on a deck of the watercraft and that has a sealed first interior space that contains satellite communication circuitry of the terminal. The waterproof container also includes a second shell mounted under the deck of the watercraft and that has a sealed second interior space that contains the processing circuitry of the terminal. The first and second shells include ports configured to receive connectors for communication signaling and/or power. The first shell can also include a pressure port to pressurize the first interior space for use in leak detection. The shells can also include heat sinks to cool the satellite communication terminal.

First claim

1 . A watercraft comprising:
first circuitry and a second circuitry; a platform with a deck; a first shell mounted above the deck of the watercraft, the first shell comprising a sealed first interior space that contains the first circuitry; a second shell mounted below the deck, the second shell comprising a sealed second interior space sized to contain the second circuitry; first ports that extend through each of the first and second shells; a pressure port that extends through the first shell and is in communication with the first interior space, the pressure port comprising an opening and a seal that extends across the opening to prevent ingress of water into the first interior space and egress of gas out of the first interior space.

2 . The watercraft of claim 1 , wherein the first circuitry is satellite communication circuitry and the second circuitry is processing circuitry, with the satellite communication circuitry being connected to the processing circuitry.

3 . The watercraft of claim 1 , wherein the first shell and the second shell are separate and independent and spaced apart from each other.

4 . The watercraft of claim 1 , wherein the second shell is mounted in a compartment within an interior of the platform.

5 . The watercraft of claim 1 , wherein each of the first shell and the second shell comprise a two-piece construction with a base and a lid configured to be sealed together.

6 . The watercraft of claim 1 , further comprising an antenna positioned within the first interior space and operatively connected to the first circuitry.

7 . The watercraft of claim 1 , further comprising a control unit mounted to the platform and positioned away from each of the first shell and the second shell, the control unit being connected to the second circuitry.

8 . The watercraft of claim 1 , further comprising one or more pressure sensors within the first interior space to detect a pressure within the first interior space.

9 . The watercraft of claim 1 , wherein each of the first and second shells comprise a waterproof rating of IP-68 to protect the first circuitry and the second circuitry.

10 . The watercraft of claim 1 , further comprising communication and power cables that connect to the first ports of the first and second shells to integrate the first circuitry and the second circuitry.

11 . The watercraft of claim 1 , further comprising a router positioned within the second interior space.

12 . A watercraft comprising:
a platform; a waterproof first shell positioned on a first side of the platform, the first shell comprising:
first and second sections that are connected together to form a sealed first interior space;
first ports that extend through the first shell and are in communication with the first interior space;
a waterproof second shell positioned on a second side of the platform away from the first shell, the second shell comprising:
third and fourth sections that are connected together to form a sealed second interior space;
second ports that extend through the second shell 30 and are in communication with the second interior space;
first circuitry contained within the first interior space; second circuitry contained within the second interior space; and connectors that extend through the platform and operatively connect the first circuitry to the second circuitry.

13 . The watercraft of claim 12 , further comprising a pressure port that extends through the first shell and in communication with the first interior space and comprising a seal that extends across the pressure port to prevent ingress of water into the first interior space.

14 . The watercraft of 12 , further comprising heat sinks operatively connected respectively to the first circuitry and the second circuitry.

15 . The watercraft of claim 12 , further comprising a pressure sensor positioned within the first interior space to detect a pressure of gas in the first interior space.

16 . A method of protecting first circuitry and second circuitry for use on an autonomous watercraft, the method comprising:
sealing the first circuitry within a waterproof first interior space of a first shell; sealing the second circuitry within a waterproof second interior space of a second shell; mounting the first and second shells to a platform of the watercraft; connecting together the first and second circuitry; and inserting a gas into the first interior space and pressurizing the first interior space.

17 . The method of claim 16 , wherein mounting the first and second shells to the watercraft occurs prior to sealing the first circuitry in the first interior space and prior to sealing the second circuitry in the second interior space.

18 . The method of claim 16 , further comprising inserting the gas through a pressure port that extends through the first shell.

19 . The method of claim 16 , further comprising inserting the gas into the second interior space and pressurizing the second interior space.

20 . The method of claim 16 , further comprising extending one of more connectors through the platform and connecting the first and second circuitry.
