Feasibility of the novel utilization of a pressure switch mechanism for re-calibrating drifted implanted pressure sensors in-situ is demonstrated. We have designed and characterized the pressure response of a system, which can quantify the offset of a sensor after it has been implanted. The benchtop device is constructed of a 25 pm thick titanium diaphragm with 10 mm working diameter. An optimization...
Bluetooth Low Energy (BLE) is a personal area wireless network technology that is of increasing importance for emerging Internet of Things (IoT) deployments. By design, BLE supports short-range, single-hop communication between a pair of BLE devices. As such, native BLE does not allow network-based policy control or in-network functions for service enhancement. These limitations are impediments to...
Medical applications, along with Information and Communication Technology (ICT), have contributed with many solutions to support the treatment of SEPSIS. However, there are few solutions for the transport of sepsis data with Quality of Service (QoS). In this paper we propose a self-manageable architecture for the provision and delivery of sepsis data using Software-Defined Networking (SDN). To evaluate...
The paper presents the laboratory based model of an “Energy Management Unit” for the optimum use of the electricity produced from alternative sources like biogas plant and solar photovoltaic system at an agriculture farm. The electrical energy produced at the farm is distributed among the loads according to the availability and requirement. A diesel generator is used as a backup at the farm. If the...
This paper presents a low-power area-efficient instrumentation amplifier (IA) for biopotential recording. The proposed IA adopts a resistor-controlled-oscillator (RCO) to change the mid-band gain of the readout circuit for different biomedical applications. The switched-capacitor load of the IA changes with RCO's output frequency, making the gain of IA continuous tunable. Measurement results show...
In a nursing home, there is an attendant blind area at night and in bathroom, and the existence of the blind area will put the elderly at potential risk. To solve the problem above, a wireless monitoring system based on ZigBee has been developed, and the system serves the functions of night off-bed detection and bathroom monitoring. The system has the characteristics of low power and low cost, and...
Multi-display environments (MDE) are replacing single-display environments (SDE) to increase productivity of users. Although, little research of MDEs was conducted in domains of limited use of computer system. One such domain is pharmacy, in which computer systems are used by pharmacists to effect payment, search for medicines and offering services to patients. In this preliminary study we conducted...
Unobtrusive in-home monitoring systems are gaining acceptability and are being deployed to enable relatives and caregivers to remotely monitor and provide timely care to their elderly loved ones or senior clients, respectively, who are living independently. Such systems can provide information about non-movement or inactivity of the elderly resident. As prolonged inactivity could mean potential danger,...
With the growth in elderly population in Singapore, healthcare expenditure and prevalence of age-related illnesses are expected to increase. Non-adherence among the elderly is a common issue that leads to adverse health complications, particularly among those with chronic conditions. However, existing studies typically focus on identifying predictors of medication adherence, and provide neither user-friendly...
The paper describes a software application running on Android mobile devices, used to help the neuromotor disabled patients to communicate with the clinicians or caretakers. The proposed application also include a telemonitoring (remote monitoring) component used to collect and process few physiological parameters of the patient. The application is part of a more complex communication and monitoring...
Multicore systems are being increasingly used for embedded system deployments, even in safety-critical domains. Co-hosting applications of different criticality levels in the same platform requires sufficient isolation among them, which has given rise to the mixed-criticality scheduling problem and several recently proposed policies. Such policies typically employ runtime mechanisms to monitor task...
This paper describes the enhancement of ultrasonic nebulizer that is being made for monitoring asthma attacks frequency and dynamics of its treatment. The improvement is presented by intercalation of an indicator that registers time, duration of an attack and dosage of an inhaled medicament. The reason why the research is regarded to children below the age of 3 years is that nebulizer therapy is the...
The paper mainly deals with the effects produced by the electromagnetic fields on the functioning of three patient-monitors in a neonatal intensive care unit. There are investigated both low frequency electric and magnetic fields (related to the operation of an universal motor and of a laptop switching mode power supply) and the electromagnetic fields associated with the GSM 2G 1800 MHz and respective...
Caregiving a person suffering from dementia or loss of brain cognitive ability due to aging is a big physical, mental and emotional burden to family members. In this paper we present a novel system for assisting caregivers at home. The system employs heterogeneous sensing and artificial intelligence technologies to automatically and unobtrusively monitor the patient; assess possible risks that the...
There are too many problems associated with clinical alarm system in Intensive Care Unit. This study was undertaken to identify and propose rectification to these problems to optimise alarm system performance. The objective of the study is to identify the problems associated with clinical alarm system in Intensive Care Units (ICU), determine the contributing factors and propose ways to improve clinical...
In this work, we developed a dual-sensor system to monitor the symptoms in gastroesophageal reflux disease (GERD). The system consists of an implantable transponder and an external reader. The passive telemetry for signal transduction is based on an inductive link between two coil antennas. The reader supplies radio frequency power, obtains and stores the backscattered sensory data. The dual-sensor...
Due to the demographic change and increased cost pressure, contactless measurement methods such as capacitive ECG become more and more interesting in research and industry. As these electrodes shall be integrated in objects of daily life to unobtrusively monitor patients (e.g. a chair or a bed), one major problem arises: no medical expert attaches the electrodes and it is a priori not known to which...
This paper present the design and implementation of a pilot smart grid in the colombian distribution network. This smart grid consists in a low voltage system connected to the existing electricity distribution network, which consider distributed generators and control, supervision and communications systems. These elements allow to provide electric power generation under the scheme of smart grid,...
Scanning Probe Microscopes (SPMs) are well known as measurement tools of nanometer scale resolution. SPMs can be used not only for surface observation but also for local surface manipulation. The typical manipulation techniques using SPM are directly transferring or scratching some samples on surfaces with the probe. However, it is difficult to control precise positioning of the probe edge at exact...
Self-adaptive applications are capable of changing their behavior thousands of times per second to autonomically find a way to accomplish given goals despite working in an unpredictable environment whose conditions can vary continuously. In this work we propose an evolvable system that runs self-adaptive applications on top of a heterogeneous system consisting of a general purpose processor and a...
