Circuit, system and method for thin-film transistor logic gates

University of Waterloo

BackgroundThin-film transistors (TFT) are widely used in large-area electronics, suchas flat-panel displays and medical imagers. Owing to being a low-cost,simpler technology, only simple circuits can be fabricated in a typical TFTprocess.Some attempts by others have been made to realize digital logic circuits ina TFT process for smart flat panel applications. However these havealways come at a great cost and substantial, wasted power consumptionthat reduces energy efficiency for portable...

LED Driver Circuit with Threshold Voltage Compensation

University of Waterloo

BackgroundThe implementation of Thin-film Transistors (TFTs) in active-matrix liquid crystal and organic light-emitting diode (AMOLED) displays has created a $100B flat-panel display market. For AMOLED, a simple 2-TFT pixel circuit does not operate with sufficient electrical stability to maintain a constant OLED drive current that results in poor pixel uniformity across the display. Various pixel circuits and driving schemes have been proposed to compensate for this electrical instability...

Visual Asset Management (VAM) Software

University of Waterloo

The VAM system offers several key novel differentiating capabilities from competitive tools. Firstly, VAM utilizes a small hand held computer tool to easily enter inspection data, including direct linking of electronic floor plans to photos taken from the site. This on-site data entry capability simplifies the data collection step and reduces the chances of data transcription errors associated with conventional paper based manual practices. The VAM system also utilizes a novel methodology to...

Visual Asset Management (VAM) Software

University of Waterloo

BackgroundThe value of large institutional assets including property, facilities, and equipment in North America is in the trillions of dollars. The effective management of the maintenance of such large capital asset platforms is very complex which makes it challenging to effectively allocate maintenance spending in an optimized way. The estimated maintenance and repair expenditure requirements in Canada are of the order of CDN$110.0 billion per year and in the U.S. such costs are of the...

Ocean Wave Harvesting by Piezoelectric Coupled Buoy

University of Manitoba

The Challenge The recent development of low powered devices and appliances, such as Light-emitting diodes (LEDs), low cost wireless sensors and wireless access points, has increased the interest in self-power techniques such as the harvesting of energy from ambient vibration. Among the available mechanic-to-electric energy conversion mechanisms, such as electromagnetic, electrostatic and piezoelectric transductions, the energy density of the piezoelectric transduction is three times higher...

High UV Efficiency Lighting

University of Waterloo

BackgroundIn conventional fluorescent lighting, electric current in the gas phase excites mercury or other ion vapor which produces a broad range of ultraviolet (UV) light, in addition to visible light. The UV light in turn causes a phosphor coating on the inside of the bulb to glow. Combination of converted and directly emitted visible light makes up the total output. Conventional fluorescent lighting systems may use multiple phosphors that coat the inside wall of a fluorescent tube....

Pure White Light Emitting Nanomaterial “NanoLite”

University of Waterloo

BackgroundConsumers and industry are seeking safe, durable, energy efficient alternatives to traditional incandescent light bulbs as this traditional form of lighting continues to be phased out (Europe started 2009, Canada in 2012). CFLs are energy efficient however they contain mercury, a toxic substance that requires special handling for disposal and in the case of bulb breakage. LEDs are a safer, longer lasting alternative to CFLs, however manufacturing White LEDs is a rather complicated...

ACCELERATOR FOR DEEP NEURAL NETWORKS

University of Toronto

A system for bit-serial computation in a neural network is described. The system may be embodied on an integrated circuit and include one or more bit-serial tiles for performing bit- serial computations in which each bit-serial tile receives input neurons and synapses, and communicates output neurons. Also included is an activation memory for storing the neurons and a dispatcher and a reducer. The dispatcher reads neurons and synapses from memory and communicates either the neurons or the...
