"Ultrasound imaging is a safe and powerful tool for providing detailed still and moving images of the human body. Most of today’s ultrasound systems are housed on a movable cart and designed for use within a clinical setting, such as in a hospital or doctor’s office. This configuration hinders its use in locations lacking controlled environments and stable power sources. Example locations include ambulances, disaster sights, war zones and rural medicine. A wearable ultrasound system, in the form of a vest worn by a sonographer, has been developed as a complete solution for performing untethered ultrasound examinations. The heart of the system is an enclosure containing an embedded computer running the Windows XP operating system, and a custom power supply. The power supply integrates a battery charger, a switching regulator, two linear regulators, a variable speed fan controller and a microcontroller providing an interface for monitoring and control to the embedded computer. Operation of the system is generally accomplished through the use of voice commands, but it may also be operated using a hand-held mouse. It is capable of operating for a full day, using two batteries contained in the vest. In addition, the system has the capability to wirelessly share live images with remote viewers in real-time, while also permitting full duplex voice communication. An integrated web-server also provides for the wireless retrieval of stored images, image loops and other information using a web-browser. "

This project takes the portrayal of memory in wearable jewellery and jewellery object making in two directions. The relationship between memory and the experiences it represents is revealed within the singular jewellery object through structural, iconographical, or material relationships among elements of the object. Reinterpretations of the original primary jewellery object result in series of jewellery objects and wearable jewellery that express ideas about the altering of memory. Jewellery objects with removable wearable jewellery components act as memory models, revealing ideas about memory processes through the relationships among their elements. The juxtaposition of soft and hard materials is used as a metaphor of memory. The result of the project is a body of work consisting of wearable jewellery and jewellery objects1 which manifest ideas about memory; specifically, the relationship between memory and the experiences it represents. The work draws on traditions in the gold- and silversmithing field of creating objects to be used as signifiers of memories3 and mnemonic devices. The primary aim of the project is not to create direct representations of personal memories or collections of found objects that represent cultural histories. Instead, the work engages in a visual and tactile exploration of memory itself: the processes of remembering experiences and the alteration of memory over time. Series of jewellery objects and wearable jewellery reveal ideas about the relationship between memory and experience both within singular objects and among altered objects in series.

Wearable antennas and electronics technology rapidly grows the last decades and leads to a future where smart textiles will be integrated into our garments. However the wearable technology research includes unsolved or of different approach challenges. This thesis deals with challenges regarding wearable antenna characterization and measurements, textile antennas feeding and textile transmission lines interconnecting. Regarding the wearable antenna characterization and measurements, a novel design of a liquid torso phantom and a new methodology for evaluating wearable antenna performance by using the cylindrical near field measurement technique are proposed. As for the textile antennas and transmission lines feeding and interconnecting, two novel methods are proposed.

Trunk-mounted monitoring equipment like GPSports SPIHPU units are designed to use global positioning (GPS), accelerometer and heart rate monitoring to evaluate the physical demands of an activity. A medical staff might also consider markers such as running symmetry in evaluation of injury occurrence and rehabilitation. A running symmetry is a ratio of the synchronization of the right and left lower limbs during the gait cycle. An asymmetry due to, a pathology or musculoskeletal injury, results in abnormal loading on the foot that may be detected by trunk-mounted accelerometry. The aim of this study is to evaluate the ability of SPIHPU units to detect running asymmetry. Subjects wore the HPISPU units (100Hz, 16g tri-axial accelerometer, 50Hz magnetometer) while engaged in various running activities. In the first study, artificially inducing a leg length discrepancy led to a difference between running symmetry scores. This discrepancy was confirmed using individual accelerometers attached to the lower leg near the foot. Next, varying running speed did not result in differences in running symmetry. However, the SPIHPU units did detect a running asymmetry between fatigued and non-fatigued conditions. Finally, two case studies showed that the units could identify asymmetry immediately after a lower leg injury and during rehabilitation of anterior cruciate ligament reconstruction surgery. The results of this study show that the HPUSPI units can be reliably used to monitor running symmetry and to detect asymmetrical gait patterns. / Master of Science
