Abstract

<B>MéTODO E APARELHO PARA FACILITAR A LIBERAçãO DE UM OBJETO PRESO POR UMA OU MAIS PORTAS QUE SE FECHAM EM UM VEìCULO DE TRâNSITO EM UM SISTEMA DE PORTA MOTORIZADA COM UMA TRAVA DE DOIS ESTáGIOS<D> Método para facilitar a liberação de um objeto preso por uma ou mais portas que se fecham de veículo de trânsito em um sistema de porta motorizada com uma trava de dois estágios, a trava de dois estágios tendo uma posição totalmente travada e uma posição de trava de recuo. O método inclui detectar a presença do objeto pelo efeito do objeto sobre a posição ou velocidade da (s) porta (s). O método também inclui determinar se a (s) porta (s) está (ão) em uma faixa de recuo entre a posição totalmente travada e a posição de trava de recuo. Se um objeto for detectado e a (s) porta (s) estiver (em) na faixa de recuo, então um ou mais sinais são aplicados a um motor da (s) porta (s) para mover a (s) porta (s) na direção de abertura da porta para ou em direção à posição de trava de recuo.<B> METHOD AND APPARATUS TO FACILITATE THE RELEASE OF AN OBJECT ATTACHED BY ONE OR MORE DOORS CLOSING IN A TRANSIT VEHICLE IN A MOTORIZED DOOR SYSTEM WITH A TWO STAGE LOCK <D> Method to facilitate the release of an object secured by one or more doors that close to a transit vehicle in a motorized door system with a two-stage lock, the two-stage lock having a fully locked position and a recessed lock position. The method includes detecting the presence of the object by the effect of the object on the position or speed of the door (s). The method also includes determining whether the door (s) is (are) in a recoil range between the fully locked position and the recoiled lock position. If an object is detected and the door (s) is (are) in the recoil range, then one or more signals are applied to a motor of the door (s) to move the door (s) ) in the direction of opening the door to or towards the recoil lock position.
