Microsystem Bart

According to Frias, Escobar, and Mendez, (2003) taken levels of human development Bronfenbrenner ecological theory are: the micro-system, which relates the level more next in which develops the individual (blood family or guardians); the meso-system, which comprises more than two environments, these include a set of micro-systems such as family or contact next of nature utilitarian and neighbouring or close relatives of the family; the exo-system includes environments that do not include the individual directly but which affect their behavior, these environments are: open relationships, friends, groups, etc. Finally found the interrelate, which comprises the systems already referred to, which are integrated or configured as culture or subculture in which the individual develops. Since taking the main conceptions of the ecological theory of human development, a development approach will be of Bart j. Simpson through the systems proposed by Bronfenbrenner: Microsystem Bart lives with his family, what sets this group as the closest to its development level, consists of Homer, Marge, Lisa and Maggie Simpson, they are structural componetess, as I mentioned earlier in the ideal model of the family. According to Frias, Escobar, and Mendez, (2003) this system can function as a trainer scope and promote optimal a development, but it can also create in individual misconduct for the rest of the systems. This is reflected in the picaresque behavior of Bart in which many of his antics are approved by his father but not by other systems. Marge represents the woman’s role centered and aware of the damage that can cause Bart, so it tries to correct the inadequate behaviors even against her husband, Lisa for his part in the majority of cases in which Bart has inappropriate behaviors can do nothing to avoid becoming a victim of their mischief, but sometimes it becomes a kind of awareness for Bart, she possesses a logical intelligence and a pre-operational thought concrete more defined than Bart which tends to disprove many of the behaviors of his brother, finally Maggie composed this first level or micro Bart system although there is no evidence a close contact to him, as he has with Lisa.


System to protect the field and its properties, SPA is the first system of security to work in weather you don’t need power. It uses sensors and sensores-trampa to detect people and situations of risk for agricultural exploitation. It is a wireless installation, does not require works or pipes. The set consists of an electronic unit, various sensors and sensores-trampa of three types and an actuator that is optional if it is necessary to activate an alarm sound or light, deterrent. Together they can become 50 per each installation.

The radius of coverage that spans can reach 150 meters. between each sensor and electronic unit. Remote communication via the mobile phone with the use of a SIM card from any telephone operator, which is inserted into the electronic unit from the outside and allows alarm programmed phones notices. Its energy management makes possible daily alarms a year. Without power, he works outdoors and flame by phone most of conventional security systems consume much power and are not prepared for the weather. More evolved need quite a few milliamps to operate, but the technology of the SPA (agricultural protection system), which is unique in the world, allows to work with very few microamps.

Sensores-trampa for detection of people SPA works in open field. Get detected and surprising a person anywhere to air free using logic: If you intend to steal must pass through a road; approaching a machine, System pivot or transformer; Enter an enclosure, shed or warehouse; Open a door, etc. Sensors for situations of risk alerts when an animal comes out a fencing, when water level is low or too high, when a place is flooded, failure of the electric current, if stop pumps, if the sprinkler system is for, or in any other application without the need for electrical power. The different elements can be hidden by a thicket, a tree, embedded in a post, on a machine or system Pivot, within an electrical box, next to a wall, buried, etc., in many different ways, that gives a high degree of effectiveness.
