Patent number: 10594409Abstract: Ultrasonic through metal communication systems are an effective solution for transmitting data across a metal barrier when the structural integrity of the barrier cannot be compromised by physically penetrating it. Substantial improvements in through metal communication systems have been made in recent years, enabling high speed communications of up to 15 Mbps, as well as power transmission up to 30 W across flat walls. A system is described that allows for ultrasonic through metal communication across the wall of a steel tube. Primary challenges of 1) transducer contact, 2) curvature effect on echoes, and 3) alignment are analyzed and addressed through the use of radial mode piezoelectric transducers, transducer “horns”, and Electromagnetic Acoustic Transducers (EMATs). The resulting system shows no significant loss due to changes in alignment, allows for the use of either piezoelectric transducers or EMATs externally, and achieves max data rates of approximately 600 kbps without echo equalization.Type: GrantFiled: December 2, 2016Date of Patent: March 17, 2020Assignee: Drexel UniversityInventors: Richard Anthony Primerano, Moshe Kam, Kapil R.

Patent number: 9853997Abstract: A malware detection system and method detects changes in host behavior indicative of malware execution. The system uses linear discriminant analysis (LDA) for feature extraction, multi-channel change-point detection algorithms to infer malware execution, and a data fusion center (DFC) to combine local decisions into a host-wide diagnosis. The malware detection system includes sensors that monitor the status of a host computer being monitored for malware, a feature extractor that extracts data from the sensors corresponding to predetermined features, local detectors that perform malware detection on each stream of feature data from the feature extractor independently, and a data fusion center that uses the decisions from the local detectors to infer whether the host computer is infected by malware.Type: GrantFiled: April 14, 2015Date of Patent: December 26, 2017Assignee: Drexel UniversityInventors: Raymond Joseph Canzanese, Jr., Spiros Mancoridis, Moshe Kam

Publication number: 20170109879Abstract: One aspect of the invention provides a computer-implemented method for tracking a plurality of spermatozoa. The method includes: identifying a coordinate for each of the plurality of spermatozoa in a plurality of video frames; and applying a nearest-neighbor joint probabilistic data association filter (NN-JPDAF) algorithm to associate the coordinates with one or a plurality of sperm tracks. Another aspect of the invention provides a non-transitory computer-readable medium containing program instructions executable by a processor. The computer-readable medium can include program instructions for performing a method as described herein. Another aspect of the invention provides a system including: a processor and a computer-readable medium including program instructions for performing a method as described herein.Type: ApplicationFiled: March 31, 2015Publication date: April 20, 2017Applicants: Drexel University, The Trustees of the University of PennsylvaniaInventors: Leonardo Urbano, Moshe Kam, Puneet Masson, Matthew Vermilyea

Publication number: 20150333943Abstract: A link adaptive orthogonal frequency-division multiplexed (OFDM) ultrasonic physical layer is provided that is capable of high data rate communication through metallic structures. The use of an adaptive OFDM subcarrier-based modulation technique mitigates the effects of severe frequency selective fading of the through-metal communication link and improves spectral efficiency by exploiting the slow-varying nature of the channel. To address the potential ill effects of peak-to-average power ratio (PAPR) and to make more efficient use of the power amplifiers in the system, the invention modifies and implements a symbol rotation and inversion-based PAPR reduction algorithm in the adaptive OFDM framework. This joint adaptive physical layer is capable of increasing data rates by roughly 220% in comparison to conventional narrowband techniques at average transmit powers of roughly 7 mW while constrained to a desired BER.Type: ApplicationFiled: December 23, 2013Publication date: November 19, 2015Applicant: DREXEL UNIVERSITYInventors: Richard Primerano, Kevin Wanuga, Magdalena Bielinski, Kapil R.

Patent number: 8010296Abstract: The present invention provides a device and method for removing non-discriminatory indices of an indexed dataset using ensemble statistics analysis. The device may include a data removal module (320) for removing non-discriminatory indices. For example, the data removal module (320) may comprise a common characteristic removal module and/or a noise removal module. In addition, the data analyzer (300) may comprise a normalization means (310) for normalizing the indexed data. The method of the present invention comprises the steps of identifying and removing portions of the set of data having insufficient discriminatory power based on ensemble statistics of the set of indexed data. For example, the method may include the steps of identifying and removing common characteristics and/or noise portions of the set of indexed data. In addition, the method may comprise the step of normalizing the indexed data either prior to or after the step of removing portions of the set of data.Type: GrantFiled: December 18, 2003Date of Patent: August 30, 2011Assignee: Drexel UniversityInventors: Lit-Hsin Loo, Leonid Hrebien, Moshe Kam

Publication number: 20050141706Abstract: A mobile agent system bridges applications and communications with next generation wireless and mobile ad hoc network infrastructures. A method utilizing middleware turns traditional applications and communications into network centric applications. Agent-based systems are used as a wrapper of existing legacy applications (or new applications that are network naive) and build methods of creating network aware agents. The network aware agents can adapt applications and communications to the changing network dynamics. An algorithmic technique divides private keys into multiple subkeys and distributes them to different nodes on a MANET using mobile agents. The mobile agents react to network dynamics to ensure that all of the requisite key components are kept within a suitable network distance from the host that owns them. Mobile agents can dynamically plan their information delivery routes to optimize any number of criteria: bandwidth impact, time, power, etc.Type: ApplicationFiled: December 29, 2004Publication date: June 30, 2005Inventors: William Regli, Moshe Kam
