  • Patent number: 11208980
    Abstract: A closed dual-bladder wave energy system that is capable of capturing a continuous supply of energy derived from wave movements for nearshore implementations. Rather than employing an onshore bladder in communication with an offshore bladder, and rather than focusing on capturing more incremental potential energy derived from tidal movement, the system accomplishes continuous captures potential energy from waves via a dual-bladder system employed offshore. Fluid within the system translates between a first offshore bladder and a second offshore bladder based on a pressure differential between a crest and a trough of a wave external to the system. By utilizing compliant bladders, the system is capable of capturing energy even during inclement weather conditions without the risk of faults resulting from strong waves. As such, the system provides for the efficient and effective capture of potential energy from waves in any weather condition and in any water environment that experiences waves.

  • Patent number: 11174831
    Abstract: A wave energy collection and conversion system that uses a compliant capture mechanism to enable the collection of wave energy over extensive distances without introducing damaging forces onto the collection structure. The system includes a flexible membrane in contact with or submerged under water, a plurality of power generation devices positioned on a sea floor, and lines that connect the flexible membrane to the power generation devices. The power generation devices each include a self-reeling mechanism and a turbine. As wave energy pushes the flexible membrane, the lines are reeled into and out of the corresponding power generation device(s). Rotation of the shaft, in turn, rotates a gear and rotator of the turbine, thus harnessing energy derived from the wave motion.

  • Patent number: 11034069
    Abstract: A problem exists of prohibitively high costs associated with molds for small run, legacy, or prototype injection molded parts. Further, the lead time on molds is currently on the order of about two weeks. A mold is provided that is formed from three-dimensional printing. The mold includes a series of air and/or water cooling channels to limit thermal stresses to the mold. Additionally, a series of coatings is added to the surface of a 3D printed mold to extend the lifetime of the mold and increase the performance of the mold. The coatings perform a function other than to define a shape of an injection cavity, such as improving thermal conductivity, providing a thermal barrier between the injection material and the mold body, or improving the detachment of the final mold product from the mold body.

  • Patent number: 10801466
    Abstract: A closed system that captures energy derived from the head differential rather than open-water flows velocities while reducing potential environmental damages and costly maintenance due to bio-fouling. The continuously derived energy system utilizes an offshore bladder in communication with both a primary onshore bladder and a supplemental onshore bladder. Tidal energy is captured by turbines as fluid is transferred between the bladders. In addition, the system continuously extracts energy by diverting fluid to and from the supplemental onshore bladder during periods of near-high-ride and near-low-tide, during which the pressure differential between the offshore bladder and the primary onshore bladder becomes inefficient for energy production.

  • Patent number: 10767619
    Abstract: A closed system that captures energy derived from the head differential rather than open-water flows velocities while reducing potential environmental damages and costly maintenance due to bio-fouling. This energy density available in a tidal range is increased substantially via convergent “nozzles” to produce an optimal speed for power generations with the turbine sections, thereby significantly increasing the tidal energy captured by this system, even at sites where tidal energy is low (e.g., small to medium tide ranges, such as found along the East and Gulf Coasts of the United States).

  • Publication number: 20170291448
    Abstract: A sprag one-way clutch (OWC) used within a cassette driver of the rear hub assembly of a bicycle. The new cassette driver delivers improved performance the reduction of rotation of the crank arm required before engagement within the cassette driver when the cyclist applies force to the pedals. Additionally, the sprag clutch smooth engagement minimizes friction loss during free-wheeling, therefore increasing drivetrain efficiency. These enhancements provide both safety and performance benefits by giving the cyclist greater control in moving between pedaling and free-wheeling. The current cassette driver design utilizes a sprag OWC for engagement without any modifications to current bicycle designs. A sprag cage may be used to provide a framework to support and properly position the sprags.
