Patent number: 11982442Abstract: Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow.Type: GrantFiled: March 9, 2021Date of Patent: May 14, 2024Assignee: Morgan State UniversityInventors: Seong W.

Patent number: 11953334Abstract: A system and method for automated routing of people and materials from one location to another based on automated vehicle technology are applied to bus transit, ridesharing and car sharing, and on multiple modes of delivery, including rail, water, road and air. An optimal transit algorithm uses Degree of Circuity (DOC) and Maximum Degree of Circuity (Max DOC) to refine transit network design and scheduling. Max DOC and computed shortest travel times are used to define the maximum acceptable travel time for each passenger or package. Using those maximum acceptable travel times for passengers and/or packages as constraints, optimal routings are developed for each primary transport hub, using a Simulated Annealing (SA) algorithm. The SA algorithm may be used as a basis for optimal flexible feeder bus routing, which considers relocation of buses for multiple primary transport hubs and multiple primary transport vehicles.Type: GrantFiled: September 10, 2020Date of Patent: April 9, 2024Assignee: Morgan State UniversityInventors: Young-Jae Lee, Amirreza Nickkar

Patent number: 11867457Abstract: A hybrid shellfish cooling system employs DC and AC cooling units using both solar power and AC electrical supply as energy sources. As temperature control and uniform temperature distribution in the cooling system are critical factors in reducing vibrio growth on raw oysters and reducing energy consumption, the system is equipped with a divider that optimizes airflow through the cooling system interior cabinet to achieve uniform temperature distribution in six individual internal compartments. Tests indicated that an average of 130 min. cooling was required to reach the suggested oyster temperatures of 7.2° C. and meet the cooling time requirement (i.e., 10 h or less). Airflow is further optimized via fan location and airflow direction, whereby configuration of a circulation fan on a lower part of the 12-volt DC section with an air supply from the 12-volt DC section to the 110-volt AC section achieves relatively uniform temperature distribution.Type: GrantFiled: June 13, 2022Date of Patent: January 9, 2024Assignee: Morgan State UniversityInventors: Seong W.

Patent number: 11824700Abstract: Systems and methods are provided for reducing peak-to-average power ratio (“PAPR”) in an orthogonal frequency division multiplexing (“OFDM”) signal having reference tones by introducing modified pilot tones to cancel peaks in OFDM symbols in the OFDM signal array. The modified pilot tones are added to the original OFDM signal, which in turn conditions the OFDM symbols of the signal to effectively reduce the PAPR. Such systems and methods provide PAPR reduction for OFDM signals generated by an OFDM Signal Processor through the addition of tone reservation PAPR reduction methods, which use reserved tones such as pilot tones to improve PAPR. Such methods offer an advantage of improving the PAPR without introducing distortion to the signal.Type: GrantFiled: November 5, 2021Date of Patent: November 21, 2023Assignee: Morgan State UniversityInventor: Richard Dean

Patent number: 11766031Abstract: A curtain enclosure formed from a flexible, non-permeable membrane is positioned adjacent to a section of riprap or similarly configured structure that has been installed along a shoreline. The curtain is stretched around rigid elongate posts and extends outward into the water from the edge of the riprap to create an enclosed containment area formed between the interior of the curtain and the edge of the riprap. The bottom of the curtain is weighted to sit along the bed of the water body and resist movement in that position. Once the curtain enclosure has been formed, larval bivalve organisms, such as oyster larvae, are poured into the curtain enclosure, and thereafter the curtain enclosure is maintained in that position for a period sufficient to promote attachment and growth of the larvae on the riprap.Type: GrantFiled: September 28, 2021Date of Patent: September 26, 2023Assignee: Morgan State UniversityInventors: Thomas F.

Patent number: 11716236Abstract: Systems and methods are provided for transmitting OFDM signals through a communication channel exhibiting frequency selective fading, such as an aeronautical 2-ray channel, using a signal modulation scheme at the transmitter that is selected based on a measurement of signal to distortion ratio (SDR) at the receiver. The SDR measurement at the receiver is used to generate an estimated best modulation scheme based on the real-time detection and measurement of SDR at the receiver, and provide feedback to the transmitter through a feedback channel of the newly selected modulation scheme. In certain configurations, the selected modulation scheme is one of multiple possible quadrature amplitude modulation (QAM) schemes, which enables adaptation of the transmitted OFDM signal to optimize throughput based on distortion of individual tones of the OFDM signal received at the receiver.Type: GrantFiled: November 15, 2021Date of Patent: August 1, 2023Assignee: Morgan State UniversityInventors: Richard Dean, Tasmeer Alam

Patent number: 11595434Abstract: Disclosed herein are methods and systems that apply a multi-layer Hidden Markov Model (HMM) for intrusion detection. The methods and systems employ a dimension reduction technique to extract only important features from network packet data and apply a decomposition algorithm to lower levels of data to construct lower level HMMs (representing partial solutions), which lower level HMMs are then combined to form a final, global solution. The multi-layer approach can be expanded beyond the exemplary case of 2 layers in order to capture multi-phase attacks over longer spans of time. A pyramid of HMMs can resolve disparate digital events and signatures across protocols and platforms to actionable information where lower layers identify discrete events (such as network scan) and higher layers identify new states which are the result of multi-phase events of the lower layers.Type: GrantFiled: May 29, 2020Date of Patent: February 28, 2023Assignee: Morgan State UniversityInventors: Wondimu K.
