  • Patent number: 12497140
    Abstract: A component that can be detachably fitted to a watercraft to shift the center of buoyancy of the watercraft and render the watercraft self-righting. The component uses quick release attachment and detachment fixtures so that a person can easily remove the component and thereby free-up space for passengers on the watercraft. The component includes a non-inflatable buoyant structure made of a buoyant material or materials arranged into a buoyant configuration. A watercraft with the detachable component is also disclosed, as is a method for converting a non-self-righting watercraft into a self-righting watercraft.

  • Patent number: 12397888
    Abstract: An aquatic rescue vehicle formed by adding directional and speed controls to a watercraft along with an autonomous control system to guide the vehicle to specified waypoints is disclosed. The rescue vehicle includes search devices such as a radio direction finder (RDF) and an infrared sensor (or camera) to be used to narrow the search for an isolated person (IP). The rescue vehicle may be discharged from a larger watercraft or an airplane and autonomously set out on its rescue mission. The vehicle may first navigate to a designated waypoint near an IP, and then use signals gathered from the RDF and infrared sensor to finally locate, assist, and retrieve the IP. The vehicle also includes a self-righting mechanism so that the vehicle can complete its mission even under the most adverse conditions.

  • Patent number: 12284465
    Abstract: An automated camera system and method are provided that are configured to search for an object emitting or reflecting a certain wavelength of light. The camera can be infrared, electro-optical, or otherwise. Image processing software is configured to isolate pixel groups in each image, wherein those pixel groups fit a wavelength or color patterns of an object being searched. The system also includes processing methods for determining the relative location of the object (GPS or other) based upon the location of the camera and the field of view of the camera. Materials can also be used to tag the object so that the object is easier to find in adverse lighting conditions. Alternatively, the tag can be a wavelength that only one group of searchers knows about, and hence the object can remain relatively hidden from others. The system can be readily mounted in an aircraft or other vehicle so that large areas can be scanned and searched.

  • Patent number: 12221192
    Abstract: A buoy, and systems and methods for rescuing people isolated on large bodies of water are disclosed. The buoy includes a remotely activatable device that is activatable when a signal is received from a remote source. The activatable device may be a signaling device, or an assistance device that is deployable by the buoy to assist in rescuing a person. A marine communication system formed by a number of spaced apart rescue buoys is also provided. A message or key other information can be transmitted to every buoy in the network via communication with just one buoy. The methods for rescuing people isolated on large bodies of water involve providing the network of communication buoys that can receive communications from the isolated person's personal communication device, and then transmit a signal to remotely activate an activatable device in a buoy to assist in the rescue of the person.

  • Patent number: 11967104
    Abstract: A method of determining the location of an object in a camera field of view is disclosed. The method may utilize a camera system that includes a digital video camera and a computer that runs image analysis software for analyzing images received from the camera. The image analysis software is configured to isolate pixel groups in each image. The method includes the steps of locating an object in the camera's field of view in which the object is represented by a set of pixels; identifying the centroid of the set of pixels representing the object; and calculating the location of the object relative to the camera based upon known parameters including the focal plane and camera lens location.

  • Publication number: 20170286965
    Abstract: A protection system for tracking and securing the purchase and sale of a controlled substance. The system includes a network and a database that stores information of a plurality of customers. The information regarding each customer is stored in an individual account, and the database further stores the information regarding government regulations on purchase and sale of the controlled substance. Also, the system includes a plurality of end user terminals to record transactions of the controlled substance. There is a server in communication with the database and the end user terminals over the network. The server includes a compliance reporting system. The compliance reporting system executes instructions to compare, in real time, information about one customer and the transaction to information stored in the database regarding the government regulations and the customer. In one embodiment, the system prevents the purchase of the controlled substance based on the comparison.

  • Publication number: 20080027851
    Abstract: A computer network and method for electronically trading derivatives. The system includes networks and methods where a control or network managing station in the network acts as a facilitator for the market makers and subscribers to make a trade at an Exchange. In another embodiment the network managing station consummates the trade between a market maker and a subscriber by matching binding quotes and orders and clears the trade at an Exchange. The computer network for electronically trading derivative comprises: (a) network managing station; (b) one or more market maker stations; (c) one or more subscriber stations; (d) one or more Exchanges. The network managing station connects market makers and subscribers for making real time indicative quotes, issuing requests for quotes, obtaining binding quotes and wherein the market maker and subscriber are in communication with an Exchange for sending binding quotes and orders to the Exchange for clearing and confirming transactions.

  • Publication number: 20070118462
    Abstract: A computer network and method for electronically trading derivatives. One preferred method of trading includes providing indicative quotes to market participants (which typically includes subscribers, but may also include market makers) to provide a non-binding indication of how the market makers are likely to price the particular derivative. A participant may then submit an RFQ, which is a request for a binding quote for the derivative. The RFQ preferably causes the current order book to be displayed on all subscribers' terminals, typically in the form of a row indicating the derivative of interest along with the current binding bid and binding ask prices. The indicative bid and ask prices may also be displayed, as well as the quantity (if any) requested in the RFQ. Market participants may then elect to submit an order for the corresponding derivative. Typically, the market participants will await an indication that a market maker has submitted a binding quote.
