V2X Vehicular Communications System

University of Waterloo

BackgroundRoad accidents represent a serious social problem and a leading cause of people death and disability in many countries. More than 93 people have been killed each day on average on the U.S. roads in 2010, plus an amount of $871 Billion of economic and societal impact on U.S. citizens due to vehicle crashes. Hence, we develop novel wireless solutions to enhance road safety by reliably and timely exchanging safety messages among vehicles. Each safety message carries vehicle status...

SYSTEM AND METHODS FOR ESTIMATING RESPIRATORY AIRFLOW

University of Manitoba

A system and methods for screening patients suspected of obstructive sleep apnea. The system includes a sound detection device configured for detecting tracheal respiratory sound signals of a patient and a Sao2 detection device for detecting Sa02 signals of the patient. The system also has a head position detection device for detecting the head positions of the patient during testing, and a processing module for receiving and analyzing the tracheal respiratory sound signals to extract sound...

SYSTEM AND METHODS OF ACOUSTICAL SCREENING FOR OBSTRUCTIVE SLEEP APNEA DURING WAKEFULNESS

University of Manitoba

A system and methods using tracheal sound intensity variations to screen patients suspected of obstructive sleep apnea during wakefulness. The system includes a mechanism positioning the patient and a sound input device attached to a recording device to receive breathing sound signals. A signal conditioning component amplifies and filters the breathing sound signals, and an analog to digital component digitizes the signals. A detecting component detects onsets of respiratory phases, and a...

INDOOR LOCALIZATION USING CROWDSOURCED DATA

University of Toronto

Methods and systems for generating a map for indoor localization. Raw data traces from a plurality of mobile devices are merged to generate a single data graph. The raw data traces represent paths traversed by the mobile devices and include received signal strength (RSS) fingerprints associated with relative points along the paths. The data graph is matched with a predefined ground truth graph defining physical coordinates of traversable paths. A radio map is generated including both the...

RUBIDIUM ELUTION SYSTEM CONTROL

JUBILANT DRAXIMAGE, Ottawa Heart Institute Research

Embodiments of the present invention provide for assessing the state of an 82Rb elution system. In certain embodiments, a system begins an assessment that comprises an elution, and a metric may be measured. This metric may be a concentration of 82Rb, 82Sr, or 85Sr in a fluid that is eluted from the generator, the volume of the fluid that is eluted from the generator, or the pressure of the fluid flowing through at least one portion of the system. If the assessment is completed, an output may...

SYSTEMS AND METHODS FOR PREDICTING MISFOLDED PROTEIN EPITOPES BY COLLECTIVE COORDINATE BIASING

University of British Columbia

Methods predict candidate epitopes in a protein by: providing a conformational sampling engine; obtaining a model of a protein suitable for use with the conformational sampling engine and comprising a native structure; applying a collective coordinate bias to the protein model, the collective coordinate bias causing the conformational sampling engine to in turn force the protein model to at least partially unfold from its native structure to an updated structure, wherein the collective...

ASYMETRICAL TRANSMITTER-RECEIVER SYSTEM FOR SHORT RANGE COMMUNICATIONS

Western University

Systems, methods, and devices relating to short range wireless communications. A host device wirelessly communicates with a user device. The transceiver on the host device is of a greater complexity than the transceiver on the user device. The host device performs a number of signal processing steps on data to be exchanged with the user device such that the complexity of the processing to be done by the user device is significantly reduced. This approach thereby reduces the complexity of the...

WLAN-TO-WLAN HANDOVER METHODS AND APPARATUS USING A WLAN SUPPORT NODE HAVING A WWAN INTERFACE

McMaster University

Methods and apparatus for use in switching communication operations between a wireless local area network (WLAN) (e.g. an IEEE 802.11-based network) and a wireless wide area network (WWAN) (e.g. a cellular telecommunications network) for a mobile communication device are disclosed. A network support node which is utilized to facilitate such transitioning has a first communication interface (e.g. an Ethernet interface) for connection with a communication network which includes the WLAN and a...

The invention may be applied to various computing devices such as CPUs, GPUs, FPGAs, etc. Methods and devices for automatically determining a suitable bit-width for data types to be used in...

TREATMENT PLANNING BASED ON MULTIPLE MODALITIES

McGill University

There is described herein methods and systems for generating a treatment plan for delivery of a radiation dose to a subject based on a plurality of radiation modalities, each radiation modality having a delivery element and an associated weight associated thereto. The treatment plan is constructed iteratively by considering the different radiation modalities and different delivery elements and selecting those that meet one or more goals regarding a target dose distribution.
