It is now widely recognized that reported energy intakes in dietary surveys underestimate usual energy intake (Black et al., 1993). During this study specific subject characteristics contributing to underreporting and the possible association between the metabolic syndrome and underreporting were investigated. A multi-disciplinary cross-sectional case-control study was carried out with 115 apparently healthy Caucasian women. The POWIRS II (Profiles of Obese Women Suffering from the Insulin Resistance Syndrome) study was performed in the Metabolic Unit of the North-West University, Potchefstroom, South Africa. Here, dietary intake was measured using the quantitative food frequency questionnaire (QFFQ). The ratio of energy intake (EI) to basal metabolic rate (BMR) was calculated from the reported EI and BMR estimated using equations. Underreporters (URs) were identified using the Goldberg equation, which compares EI with energy expenditure (EE), both expressed as multiples of the BMR. URs had reported EI 1.27 x BMR, non-URs 1.27 x BMR. Total energy expenditure (TEE) was calculated (n=115) and measured in a subgroup (n=63) by using the Actical accelerometer.

Human machine interface with dedicated software using sensors for energy harvesting. Nowadays Human-machine interfacing (HMI) motivated many studies to develop systems and devices that were able to transfer analog commands from the user's body to machines through movements. Natural evolution provided human beings with one of the most efficient mechanical interfaces with the outer environment through hands. People use their hands to interact with tools and other people every day. People in nowadays use finger movement in hand to generate energy. In this model to harvest the energy through finger movements with the support of microcontroller, piezoelectric sensor, 3-axis accelerometer.

The basic idea of the projects is to build a human machine interface which can be used to control mouse using head-tilt and eye-blink. This mouse-emulating device can be found to be most useful by physically handicapped people who can no longer control the computers using their hands. Since the device relies on user s head and eye movement, it can be used even by patient who are paralyzed from shoulder downward. Simple head movement doesn t require too much energy and neither does eye blinking. Therefore user won t get tired from using this device. In this device or goggle we are using 2D-accelerometer for detecting the movement of the head according to this, the movement of the cursor has been done. A photo sensor detects eye blinking. The Infrared transceiver consists of a 935nm IR transmitter and a phototransistor mounted on the same unit. This detects a strong increase in the reflected signal upon intentional long blink as compared to normal eye blink.

The increase in prevalence of overweight and obesity is a rapidly growing threat to the health of populations, with it affecting individuals of all ages, including preschool children. Obesity arises from an imbalance of energy intake and energy expenditure, which are influenced by many facts at many levels. Preschool children spend most of their time within the home. This study sought to measure the physical and nutritional characteristics of the home environments of preschool children, through the administration of two newly devised inventories, the Physical Activity and Nutrition Inventories, and explore the relationships between these characteristics and children's body mass index (BMI) z-score. These two inventories were then correlated with determinants of behaviour, by a food frequency questionnaire and a CSA accelerometer.

Microcontrollers are embedded into larger systems to provide benefits such as better performance, more features, better efficiency, lower costs and better dependability. This textbook introduces students to creating microcontroller-based embedded systems featuring an ARM Cortex-M CPU core. Chapter 1 introduces students to the concepts of MCU-based embedded systems, and how they differ from general-purpose computers. It then introduces the ARM Cortex-M0+ CPU, the Kinetis KL25Z MCU, and the low cost FRDM-KL25Z MCU development board. Chapter 2 presents the general purpose I/O peripheral to provide an early, hands-on experience with reading switches and lighting LEDs using C code. It also introduces the CMSIS hardware abstraction layer, which simplifies software access to peripherals. Chapter 3 introduces multitasking on the CPU, with the goals of improving responsiveness and software modularity while reducing CPU overhead. The interplay of interrupts, peripherals and schedulers (both cooperative and preemptive) is examined. Chapter 4 presents the ARM Cortex-M0+ processor core, including organization, registers, memory, and instruction set. It then discusses interrupts and exceptions, including CPU response and hardware configuration. Designing software for a system with interrupts is discussed, including program design (including partitioning work), interrupt configuration, writing handlers in C, and sharing data safely given preemption. Chapter 5 first gives an overview of tool-chain which translates a program from C source code to executable object code. It then shows side-by-side the source code and the object code the tool-chain has generated to implement it. Topics covered include functions, arguments, return values, activation records, exception handlers, control flow constructs for loops and selection, memory allocation and use, and accessing data in memory. Chapter 6 presents analog interfacing, starting with theory and ending with practical implementations. Quantization and sampling are presented as a foundation for digital to analog conversion, and analog to digital conversion. The DAC, ADC and analog comparator peripherals are presented and used. Chapter 7 presents timer peripherals and their use for generating a periodic interrupt or a pulse-width modulated signal, or for measuring elapsed time or a signal's frequency. Watchdog timers, used to detect and reset an out-of-control program, are also discussed. The SysTick, PIT, TPM and COP timers are examined. Chapter 8 discusses serial communications, starting with the fundamentals of data serialization, framing, error detection, media access control and addressing. Software queues are introduced to show how to buffer data between communication ISRs and other parts of the program. Three protocols and their supporting peripherals are investigated next: SPI, asynchronous serial (UART) and I2C. UART communication is demonstrated using the FRDM-KL25Z's debug MCU as a serial port bridge over USB to the PC. I2C communication is demonstrated using the FRDM-KL25Z's built-in 3 axis accelerometer with I2C interface. Chapter 9 introduces the direct memory access peripheral and its ability to transfer data autonomously, offloading work from the CPU and offering dramatically improved performance. Examples include using DMA for bulk data copying, and for DAC-based analog waveform generation with precise timing. An appendix covers how to measure the power and energy use on the FRDM-KL25Z board, including disconnecting the debug MCU to reduce power. Energy measurement using an ultracapacitor is also presented. For use in ECE, EE, and CS departments.
