The addition of sensors to wearable computers allows them to adapt their functions to more suit the activities and situation of their wearers. Here a wearable sensor badge is described constructed from (hard) electronic components, which can sense perambulatory activities for context-awareness. A wearable sensor jacket is described that uses advanced(More)
OBJECTIVES Around 1% of patients who have a hip replacement have deep prosthetic joint infection (PJI) afterwards. PJI is often treated with antibiotics plus a single revision operation (1-stage revision), or antibiotics plus a 2-stage revision process involving more than 1 operation. This study aimed to characterise the impact and experience of PJI and(More)
BACKGROUND Hip and knee arthroplasty are common interventions for the treatment of joint conditions, most notably osteoarthritis. Although many patients benefit from surgery, approximately 1% of patients develop infection afterwards known as deep prosthetic joint infection (PJI), which often requires further major surgery. OBJECTIVE To assess support(More)
We describe and characterize an experimental system to perform shape measurements on deformable objects using high-speed close-range photogrammetry. The eventual application is to extract the kinematics of several marked points on an insect wing during tethered and hovering flight. We investigate the performance of the system with a small number of views(More)
There is considerable controversy as to whether or not the trade in analog intellectual properties (IP) will ever represent a viable business opportunity. One school of thought suggests that analog design will always be too specialized to constitute a major market; another school of thought says this will be big business if certain nagging technical(More)
