Abstract: An autonomous underwater vehicle (AUV) may include a fuel cell charging system including a power generation subsystem having an air breathing subsystem taking intake air from the external atmosphere, a supply of compressed hydrogen in onboard storage tanks, an air-breathing PEMFC receiving the intake air and hydrogen, the PEMFC operable to produce electric energy and generating waste water, a water removal system for discharging the waste water offboard, and the fuel cell charging system having a power storage subsystem including a chargeable battery subsystem to receive electric energy to charge the chargeable battery subsystem. A system manager of an onboard data processing system may be configured to control the fuel cell charging system.

Abstract: A system to perform marine surveying may include a pair of identical design autonomous marine survey vehicles configured for coordinated operations. The vehicles may navigate and transit from a launch location to a geographically distant designated survey location, continuously survey and transit to a designated recovery location. A pair of vehicles may operate interchangeably at the sea surface, semi-submerged and underwater. Each may generate energy when operating at the surface and store energy in a rechargeable battery to power vehicle operation. The payload may include a sensor system to acquire seabed sensor data. A data storage system may store the sensor data. An on-board payload quality control system may analyze data validity. Positioning when the vehicle is collecting seabed sensor data may be determined with high precision, to provide survey data of high precision.

Abstract: An acoustic system is disclosed. The acoustic system includes a sound absorptive substrate, and a rigid polyester shell configured to be positioned over the sound absorptive substrate. The rigid polyester shell is configured to be mounted on an interior surface of a building such that at least some sound waves pass through the rigid polyester shell. The shell is configured to provide aesthetic features to the acoustic system.

Abstract: An example extraction system includes a main body having a collar coupler for coupling to a pierceable portion of a container such that the first channel is in fluid communication with the pierceable portion when the container is coupled to the coupler, where the second body end defines a second channel extending such that the second channel is in fluid communication with the first channel; and a piston defining a piston channel extending from the first piston end to the second piston end, the piston including a hollow needle fluid communication with the piston channel, where the piston is slidably disposable within the second channel such that the hollow needle of the piston can extend through the first channel to pierce the pierceable portion of the container such that the container is in fluid communication through the hollow needle, the piston channel, and the second channel.

Abstract: A method for delivering messages from customers to bots that includes providing a bot gateway and, pursuant to a process, formatting and sending the messages. The bot gateway includes bot schemas that each defines a data field arrangement for sending requests to a particular bot. The process includes receiving a first message and determining therefrom a first customer, a first tenant, a first bot, and a text message from the first customer to the first bot. The process includes: providing a bot configuration data set; selecting a first bot schema pertaining to the first bot; creating a formatted request via mapping the text message and the data values defined in the bot configuration data set to corresponding data fields defined within the data field arrangement; and sending the formatted request to the first bot.
