Sep 30, 2010: Passive Wireless Nodes for Transparent eHome Services
It is envisioned that the future smart home will have many 10’s or 100’s of wireless devices. Many of these devices will be low power, low complexity nodes to monitor security or environmental parameters. Changing the batteries in these devices or replacing them will be tedious and inconvenient. One solution is to use passive nodes, powered using energy scavenged from the wireless signal they receive from an access point designed to query the passive nodes. TRLabs has developed a passive node prototype for home security applications employing smart antenna beam-forming techniques.
Sep 15, 2010: GIS and Multi-Touch Surfaces
Most GIS applications used by utility companies are single user and runs on a regular PC. This makes paper based maps still a convenient alternative owing to its large size and ease of use in team collaboration scenarios. With the advent of Surface Computing technologies, the GIS data can now be viewed on a multi-touch surface. Multi-touch surfaces facilitates multi-user interaction and thus combines the benefits of GIS systems and paper maps. TRLabs has innovated a surface computing platform that is built on top of ArcGIS and Microsoft Silverlight/WPF with concurrency and convenience of use in mind.
Real-time video segmentation of foreground and background images is possible through the use of infrared (IR) images in conjunction with standard multi-spectral color images. To acquire IR images, a novel color field array (CFA) that incorporates IR filters and sensors is proposed. To separate foreground and background images, the IR images are used to create a mask that predicts the threshold between the foreground and background images. TRLabs has two patent applications for the technology in question: Auto Real-Time Bi-Layer Segmentation using Color and Infrared Images, and Multi-Spectral Color and IR Camera Based on Multi-Filter Array.
May 28, 2010: Agent-Based Modeling for Type-II Diabetes
TRLabs has recently completed a study that modeled the inter-actions between Type-II diabetic patients and their physicians using software agent technology. This study will provide healthcare professionals with the tools to evaluate the short and long term effects of various medical interventions, lifestyles, and frequency of blood sugar testing on the health of patients. Furthermore, this study will allow healthcare professionals to predict the financial cost of the various interventions. With a better understand-ing of the cost and effectiveness of interventions, it is anticipated that healthcare practitioners will be able to reduce cost and improve quality of diabetic treatments.
Dec 15, 2009: Fault Tolerant Schemes for Cryptography
Nowadays, cryptography involves a large a m o u n t o f d a t a computations and these computation intensive tasks require a high level of accuracy. There are two potential risks in the conventional cryptosystem which are unreliable computations and active attackers along the communication channel. Because of these risks, efficient and light-weight fault tolerant schemes for error detection and correction are crucial and indispensible. The Algorithm Based Fault Tolerant (ABFT) technique has been applied to computation intensive tasks in a variety of fields for several years. This project applies the ABFT concept to cryptosystems so the cryptographic ABFT are capable of using the existing arithemetic logic units (ALUs) embedded in the original algorithms and can be performed concurrently with the cryptographic process without exerting much influence on the original performances. Due to this superiority over the other cryptographic fault tolerant strategies, overhead can be significantly reduced.
Dec 15, 2009: Wimax for Telemedicine and Mobile Health Service
In an emergency in an emergency situation situation, how quickly a patient reaches a medical professional can determine the well being of the patient. In some cases, just an assessment of the situation by a medical professional could greatly improve the well being of the patient. Having a way for a patient to be in contact with their doctor over long distances, with the inclusion of all the medical information of the patient available to the doctor in real time could greatly improve medical practice. To solve the problem of the disconnect between doctors and patients in certain situations, TRLabs researchers have introduced the idea of using Wimax to keep patients in touch with their doctors. The proposed idea would keep ambulances, and rural medical offices connected to a central hospital in a metropolitan area. Medical information, and patient contact could all be done using IEEE 802.16-based technology. This would greatly improve the survival rate of a patient in an emergency situation.
Jul 31, 2009: Archive Planning for a Distributed PACS
In the health industry, digital imaging data are stored and processed by a system called Picture Archive and Communication System (PACS). There are two types of architectures that can be chosen to implement a PACS: centralized and distributed. The centralized system is the most common today. Our challenge is to create an architecture that uses the distributed design that is more efficient for new and current PACS.
Jul 27, 2009: An Efficient Wireless Receiver Design
The employment of transmit diversity schemes has great significance in the context of future wideband wireless communication systems since they enhance transmission reliability with no additional power bandwidth requirements. In broadband data transmissions, however, the channel fades are frequency-selective in nature, which in turn, cause severe inter-symbol interference (ISI) at the receiver. The challenge is to apply space-time block codes (STBC) in the situation where the channel is experiencing doubly dispersive fading.
