Patents by Inventor Michael Purcell

Michael Purcell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11072406
    Abstract: The present invention involves a system for the release of low relief, self-orienting deployable payloads from a platform such as a submersible vehicle and a mechanism of passive buoyancy compensation of the vehicle. The system secures one or more payloads by a vacuum force without an additional mechanical restraining mechanism and deployment of a payload is accomplished by disengaging the vacuum hold to release the payload for its intended function. Once deployed, the payload may reorient itself to a functional orientation without additional assistance.
    Type: Grant
    Filed: September 19, 2018
    Date of Patent: July 27, 2021

  • Patent number: 10174984
    Abstract: An ice making apparatus includes an ice machine for making ice with internal surfaces that come in contact with water and ice during normal operation. A cleaning container provides receiving cleaning solution to clean and disinfect the internal surfaces of the ice machine. A programmable control system controls the cleaning operation.

  • Patent number: 10112686
    Abstract: The present invention involves a system for the release of low relief, self-orienting deployable payloads from a platform such as an underwater vehicle and a mechanism of passive buoyancy compensation of the vehicle. The system secures one or more payloads by a vacuum force without an additional mechanical restraining mechanism and deployment of a payload is accomplished by disengaging the vacuum hold to release the payload for its intended function. Once deployed, the payload may reorient itself to a functional orientation without additional assistance.

  • Patent number: 9873499
    Abstract: An asymmetric propulsion mechanism capable of providing both axial thrust as well as lateral maneuverability from a single axis of rotation is described. The mechanism may be used on aquatic vehicles to minimize cost and maximize reliability and endurance. The mechanism comprises one or more propeller blades disposed asymmetrically around a rotating hub under the guidance of a control system including a motor capable of driving the propeller at various radial speeds throughout the course of a single revolution.
