Sample Collection, Annotation, Archiving, Analysis and Distribution System (SCAAAD)
BackgroundCurrent data collection and archiving methods are time-consuming and error-prone. Field scientists and technicians must carry a wide variety of sampling devices that inherently lack the ability to communicate with each other - often relying on a pen-and-paper system of recording and annotation. Further, when they exit the field and return...
Force space navigation for robotics
This system is designed to provide spatial movement tracking and robotic end-effector positioning guidance without a secondary tracking system.Background:Computerized surgical navigation is increasing. Currently, joint replacement and neurosurgery are experiencing rapid growth in the development and clinical use of such systems, which provide impro...
Touch Point Finger Pad Digitizer
BackgroundSignificant advancements have been made in non-clinical surgical training simulations - virtual reality, robotics and computer simulations have enabled a wide range of skills to be practiced and tested. However, there is still significant interest in finding ways to monitor learning progress and confirm proficiency.A surgical trainee has ...
An Asymmetrical Wireless Communication Transceiver
BackgroundExisting solutions for short range wireless communications between a host device and a number of user devices (or sensor nodes) are characterized by the symmetrical designs of their transceiver capabilities. The digital signal processing (DSP) algorithms necessary for channel equalization, compensation and synchronization require a substa...
Integrated Wireless System with Concurrent Locationing, Tracking and Communication for Location Based Applications
BackgroundPosition location technology has become increasingly important to a very broad spectrum of industry sectors, from transportation to healthcare, where accurate position location is desired under diverse circumstances. GPS is effective and accurate outdoors but works very poorly, if at all, indoors and in complex urban environments due to s...
An Adaptive Wireless Transmission Protocol to Maximize Allocation of the Radio Spectrum
BackgroundToday's prevalence of multimedia communication devices places a high demand on wired and wireless communication systems. The wide range of user applications and requirements, coupled with the fast variation of wireless channels, places added pressure on the already overcrowded and inefficiently allocated conventional radio spectrum. User ...
A Retrofit Wireless Sensor System for Industrial Plants
Background:In safety-critical industrial facilities such as oil and gas refineries, chemical processing and power generation plants, the requirements on the reliability of critical sensors are extremely high. Such sensors are typically wired and are used for emergency shutdown decision-making, process control or monitoring. Since these sensors usua...
An Embeddable Security Protocol to Address Vulnerabilities Inherent in Wireless Networks
Background:Wireless communication networks are now facing various risks of intrusion and attacks due to their lack of a physical association between the transmitter and legitimate receiver. The traditional methods to address these security issues are to use the higher layers of the OSI model which include conventional authentication and cryptograph...
Super-Hydrophobic and Super-Oleophobic Barrier Coating for Electronic Devices
Background:The electronics industry aims to deliver flexible, lightweight and inexpensive electronic products to consumers. The absence of effective barrier technologies meeting the water permeability demands is the single largest technical hurdle preventing the widespread commercialization of products such as organic solar cells (OPV), disposable ...
A Magneto-Rheological-Based Actuation System
Background:With current means of actuation, very few options exist that provide multiple degrees of freedom (DOF) and move independently without the addition of multiple motors. For instance, conventional means of safely actuating robotic devices involve the use of specially modified servo motors at each joint to control motion. In most application...
