In all of Europe and especially in Germany, there has been an increase in need for health care professionals as the average age of people is increasing due to better healthcare conditions. Most caregivers are illprepared for their role and provide care with little or no support, yet more than onethird of caregivers continue to provide intense care to others while suffering from poor health themselves. The problem is not limited to informal caregivers only but trained health professionals also experience fatigue related problems. This gives rise to the need that caregivers don’t stress themselves out physically. This internship is a part of such project that aims to tackle fatigue and stress related problems for the health care professionals. Care should be taken that nurses, caregivers or any such people who are looking after someone in their homes or hospitals maintain good health and back posture. The project intends to make a wearable device that measures and informs the person wearing the shirt/device if they are exhausting themselves. The internship specifically deals with the back posture of the person wearing the smart shirt. Bad posture can lead to lower back pain and not enough importance is given to back pain. The prevalence of low back pain is reported as over 70% in industrialized countries. Peak prevalence occurs between ages 35 and 55. Risk factors for low back pain are poorly understood. The most frequently reported are heavy physical work, frequent bending, twisting, lifting, pulling and pushing, repetitive work, static postures and vibrations. Psychosocial risk factors include stress, distress, anxiety, depression, cognitive dysfunction, pain behavior, job dissatisfaction, and mental stress at work. All of these red flags are very common in informal caregivers. The aim of the project was to design and manufacture a low cost wearable prototype that will be able to measure these things and report it to the wearer via a mobile app. The project was carried out by Mr. Halim Ibrahim Baqapuri as his Master’s thesis and I aided him in the project as my internship.

Wearable technology defines a new class of smart devices that are accessories or clothing equipped with computational power and sensors, like GoogleGlass. In this work, we propose a novel concept for supporting everyday clinical pathways with wearable technology. Our system supports clinical staff as a documenting observer, intervening adequately if problems are detected. Using the example of medication preparation and administration, a task known to be prone to errors[1], we demonstrate the full potential of the new devices. Medication identifiers are captured with the builtin camera, and the information is send to a transaction server. The server analyses new medication for possible sideeffects and interactions with already administered drugs. The result is sent to the device and the user sees all administered drugs with icons for possible drug interactions and food restrictions. Server can reduce documentation efforts and reports in realtime on possible problems during medication preparation or administration. In conclusion, we designed a secure system around three basic principles with many applications in everyday clinical work: • Interaction and distraction is kept as low as possible, user does not have to touch any buttons on device. • No patient data is displayed or being saved (images are stored only temporary). • Device is a pure observer with only small changes in existing workflow.

Bundle Adjustment is an important optimization technique in computer vision. It is a key part of Structure of Motion (SfM) computation. In this project, we are developing a system for guiding virtually impaired people with the help of smartphones and image processing techniques. Using Structure of Motion (SfM), large 3D reconstructons are created from images and videos in the form of points in the 3D cloud. Here we analyze the problem of bundle adjustment and present the state of art on this topic. We work on the existing methods and address their drawbacks; propose new methods with improvement in the direction of precision, robustness and scalability.

Indoor and outdoor navigation are challenging tasks for the visually impaired, as they cannot always depend on others for assistance. They also suffer from loss of independence and privacy. This can be avoided with the help of a mobile phone equipped with camera. The photograph of the surrounding, is captured by the phone, and sent to a centralized host. The approximate knowledge of the present location is obtained through GPS. The query image is compared with reference images (in the surroundings), stored in the database, using an image matching technique. This technique is robust to scale, lighting and rotation. This approach gives significant improvement, compared to the presently used GPS. The orientation of the camera can be determined as well. The information about the directions in which he/she can walk, will be provided through the speaker/vibration of the phone.

Since the invention of Electrocardiography by Willem Einthoven, ECG plays an important role in diagnosis of cardiac diseases. Although the importance of the deflections in ECG and their correspondence to cardiac problems were also described by Einthoven, even in today’s advanced medical practice there are application for ECG discovered each day. The growing burden of chronic kidney diseases (CKD) is another fact of today’s medical practice. The growing number of kidney patients followed by a constant number of kidney donors is a disastrous combination challenging doctors to use other methods to treat CKD patients. While advanced dialysis processes extend the life expectancy of CKD patients drastically, at the same time the high mortality rate of dialysis patients is an alarming new phenomenon. So all these new situation resulted into a foul predicament for doctors: Long transplant waiting list forces doctors to put patients under dialysis for a long time though they know how dangerous and lethal it could be. There are lots of researches happening right now with the goal of having an alternative treatment for CKD comparable with kidney transplantation (Bioartificial kidney is a good example [1]), But their goals are far from reach at least in the next ten years. For the time being, the only possible solution is to reduce the risk of dialysis as much as possible which requires an in depth of the effects of dialysis on each part of body.
