完形填空

There's nothing more welcoming than opening a door for you.（1）Without the need to be touched to open or close, automatic doors are essential in（2）improving disabled access to buildings and helping provide general（3）convenience to commercial buildings.

Self-sliding doors began to emerge as a commercial product in 1960 after being invented six years（4）successively by two Americans, Dee Horton and Lew Hewitt. They（5）started out as a novelty feature, but as their use has grown, their（6） benefits have extended within our technologically advanced world. Particularly（7）useful in busy locations and during times of emergency, the doors（8）act as crowd management by reducing the obstacles put in people's way.

（9）As well as making access both in and out of buildings easier for people, the difference in the way many of these doors open helps to reduce the total area（10）. occupied by them. Automatic doors often open to the side, with the panels sliding across one another. Replacing swing doors, these（11）allow smaller spaces to maximise the usable space inside without having to（12）clear the way for a large, sticking-out door. There are many different types of automatic door, with each（13）relying on specific signals to tell them when to open.（14）Although these methods differ, the main（15）principles remain the same.

Each automatic door system（16）analyses the light, sound, weight, or movement in their vicinity as a signal. Sensor-types are chosen to（17）compare the different environments they are needed in.（18）For example, a busy road might not（19）suit a motion-sensored door, as it would constantly be opening for passers-by. A pressure-sensitive mat would be more（20）appropriate to limit the surveyed area.
