Sense: Acceleration: is the change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, i.e. a line, acceleration is the rate at which something speeds up or slows down. Accelerometer: is a device that measures proper acceleration, the acceleration experienced relative to freefall. ■Accelerometers can be used to measure vibration on cars, machines, buildings, process control systems and safety installations. Within the last several years, Nike, Polar and other companies have produced and marketed sports watches for runners that include footpods, containing accelerometers to help determine the speed and distance for the runner wearing the unit. Accelerometers are increasingly being incorporated into personal electronic devices. Some smartphones, Digital audio players and personal digital assistants contain accelerometers for user interface control. Prominent examples include the Apple iPhone, Apple iPod touch. Accelerometers also used in Wii Rotate, laptop, camcorders, etc. ■Piezo is derived from the Greek word piezein, meaning to press tight or squeeze. Piezo Film elements are offered in four variations:

Silver ink screen printed electrodes Lamination for higher voltage output when bending Flexible leads Shielded sensors

Piezo film design kits are a good starting point to learn more about Piezo film sensors and their applications. Electromagnetic: ■Ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. It uses a galvanometer to measure the electric current through the resistance. The scale of the galvanometer was marked in ohms, because the fixed voltage from the battery assured that as resistance is decreased, the current through the meter would increase. ■Multimeter is an electronic measuring instrument that combines several measurement functions in one unit. ■Radar is an object detection system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. The first use of radar was for military purposes; to locate air, ground and sea targets. This has evolved in the civilian field into applications for aircraft, ships and roads. Process: Arduino is a tool for the design and development of embedded computer systems. consisting of a simple open hardware design for a single-board microcontroller, with embedded I/O (input/output )support and a standard programming language. The Arduino platform consist hardware and software. An important aspect of the Arduino is the standard way that connectors are exposed allowing the CPU board to be connected to a variety of interchangeable add-on modules (known as shields). The Arduino IDE(integrated development environment) is a cross-platform application written in Java which is derived from the IDE made for the Processing programming language and the Wiring project. Transform/output: The display of an image by devices such as: Movie projector／Video projector／Overhead projector／Slide projector／Camera obscura／Map projection／Graphical projection This is a class of projections for mapping a portion of the surface of a sphere to a flat image, typically a camera’s film or detector plane. In a fisheye projection the distance from the centre of the image to a point is close to proportional to the true angle of separation． Linelight Tadao Ando expresses in this work is the dual nature of existence. The space of the chapel is defined by light, the strong contrast between light and solid. Profilit:
