Summary This paper introduces an electronic circuit capable of generating a set of functions, some of them known in digital systems as the logical operators AND, OR, XOR, and so on. Using two inputs, u1 and u2, the circuit provides 16 possible output combinations. The main idea of the electronic design is based on an RC network, operational amplifiers, and voltage comparators. On the other hand, mathematically, the stable system response is used as a surface where u1 and u2 are coordinate axes forming a plane, which intersects this surface, and the output y can be seen as a circle surrounding some fixed points over this plane. The mathematical approach on this paper is intended as a groundwork for a multiple input reconfigurable logic gate that could be embedded in more complex systems. The procedure to obtain an XOR gate, represented by the ffalse(6false) function, is explained to illustrate the circuit behavior. Results of the 16 implemented functions are shown in Appendices B and C.

Resumen (español):La anemia de Fanconi (FA) es una enfermedad autosómica recesiva que se caracteriza por presentar anemia aplásica, además de malformaciones congénitas renales, cardíacas, esqueléticas, dermatológicas, y aumento en la incidencia de neoplasias malignas. Los pacientes con FA son más susceptibles de presentar sangrado e infecciones, síntomas relacionados con trombocitopenia y neutropenia. El propósito del presente reporte es describir el manejo estomatológico proporcionado a un niño de 9 años y 9 meses de edad con diagnóstico de Anemia de Fanconi, en la Clínica del Posgrado en Estomatología Pediátrica. [ABSTRACT FROM AUTHOR] Abstract Fanconi Anemia (FA) is an autosomal recessive disorder, characterized by aplastic anemia, congenital malformations in kidney, heart, skeletal and skin structures, and with increased incidence to malignancies. FA patients are likely to have bleeding and infections, which are associated with thrombocytopenia and neutropenia symptoms. The purpose of this paper is to report the stomatological management delivered to a child of 9 years and 9 months of age, diagnosed with Fanconi Anemia, in the clinic of Pediatric Dentistry.
