D1 – Explain the benefits and drawbacks of the different formats that can be used to deliver interactive media authored products.

Everytime Adobe Acrobat releases an update my computer pops up with a nessage asking if I want to update it now or later. It also gives me the option to check a box for automatic updates (updating without asking my permission). I am not required to provide a disk or file.

The ARM Cortex-M4, running at 150-MHz speed is the primary application processor catering to the high-performance needs of IoT applications; the 100-MHz ARM Cortex-M0+ processor, supports low-power operations. The PSoC 6 MCU also employs dynamic voltage and frequency scaling techniques to lower the power bar further.

Nowadays, the major limitations on computation performance are memory access latencies and power consumption. Due to memory access latency, for instance, the recently achieved CPU clock frequency of 5.7 GHz must be constraint to the maximum access speed of off-chip

When the input is positive, the digital output bit-stream contains more P bits than N bits. There can be consecutive P bits, but each N bit is separated by at least one P bit. Thus, there are no adjacent N bits when the input is positive. Similarly, when the input is negative, the output bit-stream consists of single P bits separated by one or more N bits. A Delta Sigma bit-stream toggles equally between N bits and P bits when its analog value is 0. Delta Sigma modulation is a type of Pulse Density Modulation (PDM), which means the output digital bit-stream can be converted back to an analog value using a digital moving-average filter. Therefore, in a Delta Sigma modulated bit sequence ai, which has a total of W bits, if there are n bits having the value N, and p bits having the value P, then the analog value y of this bit sequence can be written

Review literature available on popular digital logic families on the topics of ‘noise margin’ and ‘fan-out’, and write an article (of about summarizing limitations on ‘interfacing’ between two different logic families.

CMOS technology is very near to its scaling limit. Using the VLSI technology, in the recent past, researchers are facing some limitations, from practical point of view, in the approaches of CMOS technology like the short

This technological advancement facilitates the potential use of a \ac{WHTD} as a solution to relieve the burden on the health care system. The \ac{WHTD} refers to the devices which are capable of monitoring the physiological signs (e.g., heart activity, \ac{ECG}, \ac{EMG}, blood pressure, body temperature, oxygen saturation, etc.) of the human body and its surrounding environment (e.g., light, humidity, temperature, etc.) using a number of sensors located on or/and in the human body using \ac{BAN} \cite{movassaghi2014wireless,bangash2014survey,jovanov2011body}. This has been employed in various applications, such as military and sports training, \ac{HCI}, entertainment (interactive gaming), home and office automation, environmental monitoring, and \ac{VR}. It has also shown a tremendous potential as a personal healthcare system, which can provide services such as remote patient and elderly people monitoring, activity monitoring, rehabilitation, and disability assistance services as these devices can monitor health status seamlessly in real-time without disturbing users daily life. Consequently, major \ac{ICT} companies are introducing various wearable devices and services with Personalised Health Data management systems. Apple iWatch with HealthKit, Samsung Galaxy fit and Samsung Digital Health, and Google Fit are some of the

The mote’s size makes energy management a key component. The circuit will contain circuits, a temperature sensor, and A/D converter, microprocessor, SRAM, communications circuits, and power control circuits. Sensors work together with the IC, which will operate from a power source integrated with the platform.

The PI will introduce wearable sensors in undergraduate class lab sessions. Currently, an ECG recording sensor created using discrete component circuits is included as a lab session in EE380 (Electronics). The PI plans to expand this lab session, incorporating the Delta-Sigma based EEG sensor in order to show undergraduate students future trends in wearable medical devices [153,154]. The PI also plans to work with the New Mexico Project Lead the Way (PLTW) program to host workshops for K-12 teachers each year, and help them introduce wearable devices in K-12 schools (See Department

Abstract—An increase in world population along with a significant aging portion is forcing rapid rises in healthcare costs. The healthcare system is going through a transformation in which continuous monitoring of inhabitants is possible even without hospitalization. Now we are using advanced sensing systems to monitor the heart patients and provide first-aid to them in case of emergency. We now demonstrate the real time application in heart rate beat analysing by heart rate monitor and ensure proper working of heart. This paper reviews the latest

Coincident with the increase of healthcare expenditure is the technological revolution in wearable technology, bio sensors, and wireless communication. This technological advancement lead to interest in a new type of network architecture, generally known as body sensor network (BSN) or body area network (BAN), as the solution to relief the burden on the clinical system.

Many people are familiar with wearable push-button devices that can, for example, alert a caregiver in the event of a fall. But wearable technology can do much more than that. Today, healthcare providers are excited about the potential of wearable devices to monitor vital signs like blood pressure as well as early warning signs of more serious conditions like heart attack or infection.

Biomedical wearables are in a phase of accelerating development; current devices are already making strides in solving the data mystery. Current devices stress three major design elements: functionality, reliability, and convenience. (Gandhi)

Artificial pacemaker has become more and more familiar in our lives. In fact, pacemaker is a quite well-developed technology and it is widely used to treat heart issues, typically Cardiac arrhythmia which means a heart rate is too fast or too slow. In North America and Europe, Cardiac arrhythmia affects over 3% of the population [1]. 15% of total global death is caused by sudden cardiac death, and 80% of sudden cardiac death is caused by Cardiac arrhythmia [2]. Therefore, artificial pacemaker is crucial to solve this global health problem. Currently, there are over a thousand patients planted pacemaker in a million population. However, battery life has always been a problem since pacemakers were invented.
