SYSTEM AND METHOD FOR SELF-CALIBRATING, SELF-ORGANIZING AND LOCALIZING SENSORS IN WIRELESS SENSOR NETWORKS

Simon Fraser University

A method of self-organizing sensor nodes in a wireless sensor network (WSN); a method of localizing mobile nodes in a WSN; and a method of self-calibrating a WSN are disclosed. The method of self-organizing sensor nodes in a WSN includes configuring sensor nodes to in turn broadcast consecutive messages at a plurality of pre-defined and incrementally increasing power levels; detecting receipt of the broadcasted messages at each of the sensor nodes and notifying a master node as to the...

RAPID MICROWAVE PHASE DETECTION WITH A SOLID STATE DEVICE

University of Manitoba

A solid state sensor may be used to down-convert microwave signal into a low- frequency voltage or current signal, where its phase still carries the information of a measured continuous wave (CW) microwave phase. Two CW microwaves may be mixed and a solid state sensor used to rectify the mixed microwave into a direct voltage or current signal. The measurement system may include an input node for receiving a microwave signal from a source from which the output microwave is coherently split...

METHOD AND APPARATUS FOR SIGNAL ACQUISITION IN OFDM RECEIVERS

Laval University

A method and apparatus for signal acquisition in an OFDM receiver relies on a preamble training sequence to synchronize the receiver in time (e.g. determining the start of a frame) and in frequency (carrier frequency offset compensation). The preamble training sequence has a periodic structure and the method and apparatus perform a cross- correlation technique using a matched filter to achieve time synchronization and / or frequency synchronization and / or channel estimation, the latter...

SECURE LINKAGE OF DATABASES

Privacy Analytics, University of Ottawa

A secure linkage between databases allows records of an individual in a first database to be linked to records of the same individual in a second database without disclosing or providing personal information outside of either database or system responsible for controlling access to the respective databases As such, records of individuals may be securely linked together without compromising privacy or security of the databases.

DEVICE AND METHOD FOR PREDICTION OF ACUTE HEART FAILURE MORTALITY

SUNNYBROOK RESEARCH INSTITUTE, University Health Network

Various embodiments are described herein for a device and a method that can be used to determine a Heart Failure (HF) risk score for an individual with a risk of acute heart failure. The technique comprises employing a HF risk model that uses demographic, transportation, vital signs, blood test, medication and pre-existing co-morbid information to determine the HF risk score for the individual.

COMPUTER-AIDED LOCALIZATION OF SITE OF ORIGIN OF CARDIAC ACTIVATION

Dalhousie University

A method for quantifying, during pacemapping, a comparison of a BSPM of interest to a pace site BSPM. The method may include receiving at a computing device a plurality of ECG signals from an acquisition system. The pace site BSPM may be calculated using the plurality of ECG signals. The BSPM of interest may be compared to the pace site BSPM, by: retrieving the BSPM of interest from memory accessible by the computing device; and, calculating one or more comparison metrics for the BSPM of...

The method may include receiving at a computing device a plurality of ECG signals from an acquisition system. The pace site BSPM may be calculated using the plurality of ECG signals. The BSPM of interest may be compared to the pace site BSPM, by: retrieving the BSPM of interest from memory accessible by the computing device; and, calculating one or more comparison metrics for the BSPM of...

METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR UTLIZING BRAIN STRUCTURAL CHARACTERISTICS FOR PREDICTING A DIAGNOSIS OF A NEUROBEHAVIORAL DISORDER

COLLEGE OF CHARLESTON, McGill University, University of North Carolina at Chapel Hill

Methods, systems, and computer readable media for utilizing brain structural characteristics for predicting a diagnosis of a neurobehavioral disorder are disclosed. One method for utilizing brain structural characteristics for predicting a diagnosis of a neurobehavioral disorder includes receiving brain imaging data for a human subject of at least one first age. The method also includes determining, from the brain imaging data, measurements of brain structural characteristics of the human...

DEVICES AND METHODS FOR QUANTIFICATION OF MALE FERTILITY

University of Toronto

Disclosed herein is a low cost and rapid microfluidic based method and test device for quantifying male fertility potential. The device can simultaneously measure three critical semen parameters rapidly, namely live sperm concentration, motile sperm concentration, and sperm motility. The device includes a transparent substrate and a top sheet with two holes therethrough and an intermediate sheet sandwiched between the substrate and the top sheet. The wells formed by holes form a...

SYSTEM AND METHOD FOR MULTIPLEXING OF VARIABLE BIT-RATE VIDEO STREAMS IN MOBILE VIDEO SYSTEMS

Simon Fraser University

A method of transmitting a live video stream and a pre-recorded video stream over a wireless network to a mobile device, the method including: receiving the live video stream and the pre-recorded video stream for a current scheduling window; dividing the live video stream and the pre-recorded video stream into segments in the current scheduling window, each segment including an aggregate data amount, a transmission start time and a transmission end time; determining a transmission schedule...
