Abstract: Portable, low cost, high speed surface and subsurface vehicles for aquatic data collection, payload delivery, or water quality monitoring. The vehicles can be deployed in pods enable rapid large scale data collection across a wide area. The vehicles are capable of transiting the water surface at speeds of over ten knots, and can also be propelled under the water surface and dive vertically to the floor of the water body. A passive, non-powered internal weight transfer system enhances the vehicle's performance in each of its transit modes. The vehicles can have one or more of the following features: high speed stabilizing wings, a tool-less assembly system, sacrificial standoffs for vertical dives, sacrificial protectors for the control surfaces, and/or a universal mounting system for attaching payloads such as sensors.

Abstract: A scent dispenser/absorber includes a container, an invertible lid reversibly attached to an open end of the container, a vented cage, and a scent cartridge housed within the cage. In an “off” condition or state, the scent cartridge/cage combination is received in an interior chamber of the container, where the scent cartridge is out of communication with the surrounding environment and therefore incapable of performing scent dispensing or absorbing functions. The scent dispenser/absorber can be switched to an “on” condition or state by manually inverting the lid and, in some cases, the associated cage/scent cartridge combination, such that the scent cartridge can be positioned externally of the container, where it can communicate with the surrounding environment to perform a desired scent dispensing or absorbing function. In an “on” condition, scent molecules originating from an odorant contained in the scent cartridge are diffused into the surrounding environment.

Abstract: A device may obtain data associated with an event and process the data via an evacuation prediction and management engine to obtain an evacuation prediction. When the evacuation prediction indicates that an evacuation order is likely to be issued within a period of time based on the event occurring, the device transmits, via the evacuation prediction and management engine, an evacuation service offering to a user device. Upon a user of the user device confirming acceptance of the evacuation service offering, the device receives a payment for the user for the evacuation service offering. When the event or evacuation order occurs and based on the payment for the evacuation service offering, the device automatically initiates a payment to a user account.
