Abstract

Se proveen los sistemas y metodos para controlar la deteccion de un ocupante en un area de asiento; el ocupante se caracteriza como un adulto, nino u otra categoria; un parametro de cambio de caracterizacion, tal como un periodo de histeresis o umbrales para caracterizacion, se aplica para un primer periodo, despues de ese periodo, el parametro de cambio de caracterizacion se cambia; por ejemplo, si la caracterizacion permanece igual durante diez segundos, la histeresis se cambia de cinco a diez segundos; como otro ejemplo, si la caracterizacion permanece igual durante un minuto, los umbrales relacionados con esa caracterizacion se amplian para disminuir la probabilidad de un cambio en la caracterizacion; en algunos sistemas y metodos; un parametro de confianza o probabilidad relacionado con la caracterizacion se utiliza para controlar los cambios del parametro de cambio de caracterizacion; en algunos sistemas y metodos, el parametro de cambio de caracterizacion se restablece en respuesta a una de (a) una caracterizacion de no ocupante o (b) caracterizando al ocupante como uno diferente de al menos dos categorias consecutivamente para un periodo de histeresis actual.
