WIRELESS-ENABLED AIR QUALITY MONITORING AND CONTROL

Kwantlen Polytechnic University

The present invention provides a wireless-enabled air quality monitoring and control system, apparatus and associated method. One or more sensor input modules provide input signals representative of one or more aspects of indoor air quality, such as CO2 level, temperature, and humidity, to be processed by a control module. The control module is configured to provide control signals based at least in part on the input signals in accordance with a control scheme. The one or more control...

MICROFLUIDIC RECONFIGURABLE DEVICE FOR MULTI-PLEXED SAMPLE ANALYSIS

Simon Fraser University

A recontigurable microfluidics multiplexing device for biological and chemical sample analysis. The device comprises a cartridge having one or more sample fluid tracks in a single plane, an array of electronically programmable valves capable of being configured to alter fluid steering in the fluid tracks, a means for interfacing the array with the fluid tracks, a means of controlling fluid flow in the fluid tracks, and a user interface to direct the control of valves via control logic within...

Operating environment analysis techniques for wireless communication systems

McMaster University

There is described a method for spectrum hole prediction, the method comprising: sensing a stimulus in an operating environment of a wireless communication device; identifying a frequency band having an interference level higher than a threshold based on an analysis of said stimulus; performing a traffic model on said frequency band based on historical traffic data; and applying a predictive model on said traffic model to predict when said frequency band will become a spectrum hole.

ADAPTIVE VOICE PACKETIZATION

McMaster University

A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality...

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...

SYSTEM AND METHOD FOR DIGITAL ENHANCEMENT OF HIPPOCAMPAL REPLAY

Governing Body of The University of Toronto, University of Toronto

There is provided a system, method, and computer program for digital enhancement of hippocampal replay. In an embodiment, the method includes: creating one or more digital memories, each digital memory created by: receiving a tag associated with the digital memory from a user; receiving a captured digital memory from the user; and associating one or more additional attributes with the digital memory; creating a replay session, the replay session comprising one or more digital memories, by:...

SYSTEM AND METHOD FOR GENERATING VISUAL IDENTITY AND CATEGORY RECONSTRUCTION FROM ELECTROENCEPHALOGRAPHY (EEG) SIGNALS

University of Toronto

There is provided a system and method for generating visual category reconstruction from electroencephalography (EEG) signals. The method includes: receiving scalp EEG signals; using a trained pattern classifier, determining pairwise discrimination of the EEG signals, the pattern classifier trained using a training set comprising EEG signals associated with a subject experiencing different known visual identities; determining discriminability estimates of the pairwise discrimination of the...

SENSOR SYSTEMS AND METHODS FOR ANALYTE DETECTION

McGill University

Systems for analyte detection are disclosed. The system includes absorption channels positioned along a surface of an object. The absorption channels are configured to trap an analyte. The system further includes a sensor embedded in the object and configured to detect the presence of the analyte. The sensor includes a light source configured to transmit light and a detector configured to detect a change in an intensity of light transmitted by the light source. The sensor further includes a...

ADAPTIVE ENERGY MANAGEMENT SYSTEM

McMaster University

Systems, methods, and devices related to a microgrid system for providing power to a facility. A self-contained power system provides power to a facility using a combination of power storage elements and renewable energy sources. A connection to an external power grid may also be provided. The system optimizes power flow to the facility using power from the storage elements and the renewable energy sources and, if necessary, the external power grid. The optimization process predicts future...

VISION STRENGTHENING METHODS AND SYSTEMS

McGill University

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and...
