 The design and construction of a device prototype for a water level measurement system in a tank and controlling a number of garden light analogies has been carried-out and the prototype can be integrated into smarthome system. Three topics are discussed in this paper, including the manufacture, programming, and performance measurement of device prototypes. The formation of prototype of the device is done through wiring integration between electronic devices, in order to obtain the hardware handshacking. Programming the prototype of device is done through the creation of algorithms and preparation of syntax, in order to obtain the software handshacking. The performance of the prototype of device is measured when integrated into the Smarthome system, in order to obtain the hardware and software handshacking. The performance of prototype of the device when monitoring in the form of information about the water level in the water tank with 3 (three) conditions, namely the criteria of "empty", "medium", and "full", while the control in the form of information about the operation of ON/OFF of the LED as an analogy to the lamp garden are done for 3 (three) positions, namely position #1, #2, and #3.

Use Of Internet

This chapter introduces the use of middleware tools in applications for healthcare and social services, focusing on solutions designed for Interactive Digital Television (IDTV), and discusses its implications to modern roles for easing patient and caretaker relations. The authors explore the capacities of such solutions to assist the patients in their personal needs, optimizing the time and tasks of the caretaker. They discuss the limits of the use of Internet in satisfying the needs of communication of elderly and other patients, and then they propose new roles for caretaking based on this new reality. The authors also present an architecture that allows the remote use and control of electronic devices via IDTV set-top boxes for the middleware Ginga. They show applications based on this architecture that promote healthcare and social services, as a set of infrared lights coupled to a hat that can be used as input for impaired patients, and how an accelerometer can be used with IDTV applications for treatment and entertainment. Before concluding, the authors point out research directions on the topics discussed in this chapter.

Self-heating operation, or the use of the resistance-probing signal to warm up and control the temperature of nanowire devices, has been the subject of research for more than a decade. The state-of-the-art shows that this approach is serving to lower the power demand in temperature-activated devices, especially in conductometric gas sensors, but the simplicity of eliminating the heating element comes with the complexity of integrating 1-dimensional nanomaterials in electronic devices. The advantages of the efficient self-heating effect in nanowires have already been probed in a broad range of systems and materials. But when it comes to transfer this operating principle to new systems and materials natural doubts arise: how to do it?, how much savings in power will be achieved? We will address these questions in this review contribution.

A novel distributed control ideology and technology will be described for management of advanced crisis relief missions. The approach is based on the installation of a universal “social” module in highly portable electronic devices, like laptops and mobile phones, which can collectively interpret a spatial scenario language, exchanging high-level program code (waves), data, and control with other modules in a parallel fashion. This technology can dynamically integrate any human and technical resources that were scattered postdisaster into an operable, distributed system capable of solving—autonomously—complex survivability, relief, and reconstruction problems.

Today, there is an innumerable amount of electronic devices and computer systems that are oriented as platforms for the management of information through the network; manipulating data and at the same time, performing tasks using low voltage electronic signals. They can activate, deactivate or control a device or a system using sensors. In this context, the Raspberry Pi platform has an interface composed of a set of pins (GPIO) through which voltage signals can be accessed, and can interact with other electrical and electronic systems for data acquisition and control. This article aims to facilitate access to the Raspberry Pi platform from its installation, configuration, to its programming of the ports through examples and instructions, considering the platform as a computer system. The interest of the authors is to provide the reader with the tools, so that the programming of specific applications is the new challenge.

Defect Densities

The measurement of oxygen precipitate defect densities in Czochralski (CZ) Silicon wafers after standard heat cycles, or at strategic points in the device manufacturing process is often used as a tool to understand the oxygen precipitation behavior of the wafers on which electronic devices will be manufactured and to measure variability in the precipitation . The relevance of these measurements arises from the fact that controlled oxygen precipitation in the bulk of the wafer is used as a means to ‘getter’ unwanted impurities from the device layer of the wafer, and control of oxygen precipitation can be an important factor in device yields.Typically the density of oxygen precipitate in a given wafer and the depth profile is determined by physically counting defects on cleaved slices after preferential etch to reveal the defects . This is a fairly time-consuming and a destructive test. However in the last few years a number of companies have developed computerized, non-destructive IR laser scattering instruments which rely on the fact that silicon is transparent to IR., and a precipitate (having a different refractive index from silicon ), will scatter some of the laser beam which can be detected.
