Adaptive ultrasound detecting system for a door assembly
First Claim
1. An adaptive ultrasound detecting system for a door assembly, the door assembly being for closing a door entrance and including a door movable along a path;
- the system comprising;
an ultrasound transducer assembly including a plurality of ultrasound transducers mounted to the door assembly adapted to emit at least one ultrasound detecting beam within the door path, to receive an echo indicative of a body located within the door path when the body intersects one of the at least one ultrasound detecting beam, and to trigger a detecting signal indicative of the body within the door path;
a controller coupled to the ultrasound transducer assembly adapted for receiving information indicative of a position of the door along the path, and for varying the emission of at least one ultrasound detecting beam in accordance to the position of the door relative to the at least one detecting beam;
wherein varying the emission of at least one ultrasound detecting beam includes temporarily triggering off at least one of the plurality of ultrasound transducers;
wherein temporarily triggering off at least one of the plurality of ultrasound transducers includes sequentially triggering off each of the at least one of the plurality of ultrasound transducers before the door penetrates the corresponding one of the at least one ultrasound detecting beam.

Abstract
Embodiments of an adaptive ultrasound detecting system for a door assembly include an ultrasound transducer assembly mounted to the door assembly and a controller coupled to the ultrasound transducer assembly. The ultrasound transducer assembly is adapted to emit ultrasound detecting beams within the door path, and to trigger a detecting signal indicative of a body located within the door path when the body intersects at least one of the ultrasound detecting beams. The controller is adapted to receive information indicative of a position of the door along the path, and to vary emitting at least one detecting beam in accordance to the position of the door relative to the ultrasound detecting beams.

18. An adaptive ultrasound detecting system for a door assembly, the door assembly being for closing a door entrance and including a door movable along a path;
- the system comprising;
an ultrasound transducer assembly including a plurality of ultrasound transducers mounted to the door assembly, adapted i) for an emission of at least one ultrasound detecting beam within the door path, ii) to receive an echo indicative of a body located within the door path when the body intersects one of the at least one ultrasound detecting beam, and iii) to trigger a detecting signal indicative of the body within the door path; a controller coupled to the ultrasound transducer assembly adapted for receiving information indicative of a position of the door along the path for varying the emission of at least one ultrasound detecting beam in accordance to the position of the door relative to the at least one detecting beam, for recognising a signature of the door and for removing the signature of the door from each received echo from one of the plurality of ultrasound detecting beam that is at least partially penetrated by the door; wherein varying the emission of at least one ultrasound detecting beam further includes triggering of each of the plurality of ultrasound transducers that produces a detecting beam that has been penetrated by the door after the detecting beam is completely passed by the door.
- the system comprising;
