Advances in networking, sensors, and embedded devices have made it feasible to monitor and provide medical and other assistance to people in their homes. Aging populations will benefit from reduced costs and improved healthcare through assisted living based on these technologies. However, these systems challenge current state-of-the-art techniques for usability, reliability, and security. In this paper we present the PAS open architecture for assisted living, which allows independently developed third party components to collaborate. We discuss key technological issues in assisted living systems, such as tracking, fall detection, security and privacy; and results from our pilot study in a real assisted living facility are presented.

Technological advances and critical needs have led to medication administration devices and tools designed to prevent and reduce medication errors. They include smart medication carts, robots and dispensers for professionals and smart dispensers for naive users. This paper describes architectures and interfaces of these devices. It also discusses support environment that is needed to increase their effectiveness and missing standards that will enable their integration into medication process tool chain.

Falls are increasingly among the leading causes of elderly injuries and deaths each year. Several of these victims depend on a walking stick or cane for support while walking. Rendering aid more quickly to those who fall may decrease the severity of injury in several cases. In this paper, we propose a dynamic fall detection system embedded into walking sticks and canes. By using a gyroscope chip to measure angular velocity of the stick, we can detect when a user may have fallen. Also monitored by the detection system is the user's walking pace, such that the user will be warned when traveling at paces above his or her normal speed. With different polling frequency levels to preserve energy, we present a low-power device that can potentially improve safety among the elderly.

In this position paper, we propose an analysis, architecture and design approach to specify and enforce certifiable behavior as a means for meaningful and economically feasible certification argument construction in the context of distributed, adaptable safety-critical software systems. The main components of our approach are: 1.) methods to identify and separate uncertifiable behavior based on system observables. 2.) Extending interface standards to complement certification activities. 3.) Methods for regulating component interaction. 4.) Methods to dynamically, constrain behavior into localized, certifiable operating regions.

The use of medications is ubiquitous in terms of location and time. Medication-use system includes the prescription entry sub-system in hospitals and clinics, prescription refill subsystems in pharmacies, and medication dispensing subsystems for medication users. Fortunately, many of the medication-use injuries are preventable. Integrating medication sub-systems and automating the medication process enhance the medication compliance and prevent the medication errors, caused by communication mistakes between care-takers and medical institutes. There are many attempts to integrate medication-use sub-systems to help the patient in hospital or outpatient settings to comply with medication directions. Many of them are designed and implemented with typical medication-use process and most of the systems are implemented as a tightly-coupled close system.

A clinical work flow is comprised of the sequential events that occur during a specific patient/clinician interaction. Clinical workflows track the human interactions involving equipment, staff, patients, supplies and other elements of the day-to-day environment. Understanding how these interactions work and translating this understanding into well-designed medical technology are vital to patient safety. The healthcare environment is more difficult to understand due to the increased number of unpredictable human interactions in the system. This is often related to culturally-inherited deviations from administrative standard procedures (work-arounds) with technology or processes. These workarounds are often unidentified, misunderstood or ignored during new product development, as the traditional input specifications are derived from widespread market research or limited input from the product's sales or technical support teams. A well-designed integrated system incorporates a thorough understanding of these workarounds, based on analyzing the relevant clinical workflows and using these workflows to inform a system's use-case development. This approach can result in comprehensive design input specifications for use in building the technology.

To allow for an efficient usage of a device in pervasive computing environments when a user intends to selectively utilize multiple devices within his/her vicinity, reliable and yet convenient authentication is an important requirement. The problem becomes more complex when the accessed device is shared by the public with many different individuals. This paper first illustrates the issues of establishing sessions to such devices (logging in, maintaining a session, and logging out), and then identifies the common pitfall of access-control contexts. We propose an improved context-aware solution that supports a secure, selective, and identifiable user access of public shared devices with high usability.

MD-adapt is an architecture for shamble common interfaces for medical devices in support of the goals of MDPnP. This paper proposes an architecture for enabling an open source, community-based effort to create a pool of reusable device interface implementations. The MD-adapt architecture consists of a standardized API (application programming interface) and a device metadata format, and supports building modular and portable medical device communications software adapters that run on a variety of relevant OS platforms.

Low-cost sensors and wireless systems can now create a constantly vigilant and pervasive monitoring capability at home, at work, and in conventional point-of-care environments. While progress in this area is underway in sensor technology, mobile computing platforms, and data transport, barriers to large scale application remain ahead, particularly in the area of patient disease diagnosis, which generally requires a diverse set of sensors and instruments that are applied at proper times in response to patient state/behavior. As these sensors may be numerous, and may not be worn comfortably and practicably at all times, a solution is required for the systematic selection of sensors at the point of use. We describe the Incremental Diagnosis Method (IDM) system, an embedded decision support system based on Bayesian statistics and decision analysis theory developed to select or deselect available sensors so that the diagnostic certainty of patient condition best improved while the set of sensors used on the patient body is minimized. IDM has been evaluated in a testbed, the Medical Embedded Device for Individualized Care (MEDIC) system, based on standard, ubiquitous wireless platforms. MEDIC supports local sensing and signal processing, autonomous decision support, and remote reconfiguration and control of wearable components. A detailed evaluation of IDM operation and performance for patient gait analysis is also given in this paper. Finally, we also discuss the many new opportunities provided by IDM and the related future research introduced by this capability.

MediCANTM represents a network architecture that was designed as a vendor-independent technology for interfacing bedside medical instrumentation. It is compatible with almost all medical instrument technologies and data communications protocols. In contrast to IEEE X73, MediCANTM sought to integrate the most suitable off-the-shelf technologies that were already proven and up-to-date with cost-effective availability. MediCANTM is highly scalable in regards to interfacing with instruments on the lowest end of complexity level (i.e., thermometer) to pulse oximeter or higher complexity. In addition, a simple interface is going to connect a fiber-optic sensor to provide heart and body motion data for continuous monitoring of patients. MediCANTM has been designed to utilize internet tools to track operations related to healthcare administration to decrease costs.
