An underwater vehicle includes a modular battery system. The modular battery system includes at least one removable battery tray. The modular battery system further includes a battery tray system configured to hold at least one removable battery tray. The modular battery system further includes a controller coupled to the at least one removable battery tray that is configured to detect the battery chemistry of the at least one removable battery tray.

A quick release bow clamp comprising a hinged circular body having a vehicle mating flange and a nose cone mating flange configured to selectively attach to an access plate on the bow of an underwater vehicle and a nose cone for the same, respectively. The flanges of the bow clamp and the corresponding flanges of the access plate and nose cone may include an intermittent pattern of open and solid portions for weight reduction. The bow clamp may also include a quick release clamp having an adjustable draw latch configured to attach to a clip on the body of the bow clamp and a safety latch configured to prevent the draw latch from inadvertently disengaging with the clip.

A tool-less joiner clamp includes a hinged circular body having a forward mating flange and an aft mating flange configured to selectively attach to a forward section flange and an aft section flange of an underwater vehicle, respectively. The forward mating flange has a threaded inner diameter configured to integrate with a threaded outer diameter of the forward section flange, such that rotating the joiner clamp about the forward section flange causes the clamp to move in an axial direction. Also included is a cam lock for selectively closing and tightening the tool-less joiner clamp onto the forward and aft section flanges of the vehicle and may include a quick release mechanism for opening the cam lock. The clamp may also include collapsible handles, and multiple buttons configured to press against a flat surface of the aft mating flange when the joiner clamp is rotated about the forward section flange.

An unmanned undersea vehicle includes one or more vehicle sections. The sections include a vehicle hull. The vehicle includes a data crypt configured to be selectively removable from the vehicle through the hull of the vehicle. The data crypt includes a persistent storage device configured to operate using SATA protocols and one or more electrical connectors configured to selectively connect the data crypt to electrical equipment in the vehicle, wherein the connectors are impedance matched to mating connectors in the vehicle.

An underwater vehicle system includes a data security system. The data security system includes a data pod including persistent storage. The persistent storage stores encrypted data. The security system includes a watchdog. The watchdog includes at least one processor. The security system includes a watchdog key. The watchdog key is stored in volatile storage. The watchdog key is configured to be used to decrypt the encrypted data. The data security system is configured to remove the watchdog key from the underwater vehicle system, thereby preventing access to the encrypted data on the data pod.

Data storage device

An acoustic Doppler system comprising a plurality of acoustic transceivers, an acoustic subsystem controller and a main processing unit operatively connected to the acoustic subsystem controller. A first of the plurality of acoustic transceivers operates at a first acoustic frequency and is operatively connected to a first group of transducers producing an acoustic signal. A second of the plurality of acoustic transceivers operates at a second acoustic frequency and is operatively connected to a second group of transducers producing an acoustic signal. The first and second acoustic transceivers are adapted to operate concurrently at the first and second acoustic frequencies. The acoustic subsystem controller is operatively connected to the first and second acoustic transceivers and controls the acoustic signals produced by the first and second group of transducers. The main processing unit is adapted to execute instructions to the first and second group of transducers to produce acoustic signals having at least two frequencies and is adapted to run at least two processing methods concurrently. The main processing unit analyzes data received by the first and second group of transducers, automatically adjusts the acoustic frequencies of the acoustic signals produced by the first and second group of transducers, and automatically selects a method of processing the data received by the first and second group of transducers.

Multi-frequency, multi-beam acoustic doppler system with concurrent processing

An acoustic Doppler system including an acoustic subsystem controller operatively connected to a plurality of acoustic transceivers, with a first of the plurality of acoustic transceivers, operating at a first acoustic frequency, operatively connected to a first group of at least one transducer, and a second of the plurality of acoustic transceivers, operating at a second acoustic frequency, operatively connected to a second group of at least one transducer, where the acoustic subsystem controller includes a digital circuit configured to sample analog signals received from the first and second groups of transducer in pairs having a pair-wise sampling frequency that is four times the operating frequency of associated acoustic transceiver. Also presented is a method of sampling acoustic Doppler signals received from such devices, with samples comprising a pair of values taken with a pair-wise sampling frequency that is four times the operating frequency of associated acoustic transceivers, and the resulting pairs of values being further processed as representative values of the cosine and sine components of a Doppler-shift signal.

Multi-frequency, multi-beam acoustic doppler system

An underwater sensor device comprises a submersible housing including one or more housing components, one or more sensors for monitoring and collecting water characteristics, a controller for controlling operations of the one or more sensors and an graphical user interface mounted to the housing that displays the water environmental data. The housing defines a channel that extends through one of the housing components, and at least one of the sensors is mounted to the housing and extends into the channel. The controller is disposed within the housing and is operatively connected to the one or more sensors.
