Abstract

In a system and a method for determining closed and open states of closeable and openable passages of an object, components are configured to determine whether a closeable and openable passage is in an open state or in a closed state and are all arranged exclusively on one spot associated with the passage providing closing and opening of the passage.

Claims

1. A system for determining closed and open states of closeable and openable passages of an object, comprising

components which are configured to determine whether a closeable and openable passage is in an open state or in a closed state and which are all arranged exclusively on one spot associated with the passage providing closing and opening of the passage,

wherein the all components are arranged in a ground, or in a threshold adjoining a residence, or recessed in a component of the passage.

2. The system of claim 1, wherein the system includes means for preliminary calibration and subsequent determination of the open state of the system based on deviation of obtained calibration data.

3. The system of claim 1, wherein the components include a proximity antenna and a communication antenna configured so that when the system transmits through the proximity antenna a signal is supplied to the proximity antenna through one feed element, when the system transmits through the communication antenna a signal is supplied through another feed element, and when the same antenna is used for communication and for proximity detection a proximity detection signal and a communication signal are supplied through a same feed but in different time frames.

4. The system of claim 1, wherein the components include a reflection lens so that a light waveform is transmitted through the reflection lens from a door plate and light is reflected from a door frame through the lends to a sensor which measures for each wave light transition a time of light in comparison to a time of light when the sensor was calibrated, to thusly identify whether a door is open or closed, and the lens provides spinning of an optical sensor wave by 45 degrees.

5. A method for determining closed and open states of closeable and openable passages of an object, comprising

configuring components to determine whether a closeable and openable passage is in an open state or in a closed state;

and arranging all components exclusively on one element associated with the passage providing closing and opening of the passage,

and arranging the all components arranged in a ground, or in a threshold adjoining a residence, or recessed in a component of the passage.

6. The method of claim 5, wherein the method includes carrying out preliminary calibration and subsequent determination of the open state of the system based on deviation of obtained calibration data.

7. The method of claim 5, wherein the components include a proximity antenna and a communication antenna operating so that when the system transmits through the proximity antenna a signal is supplied to the proximity antenna through one feed element, when the system transmits through the communication antenna a signal is supplied through another feed element, and when the same antenna is used for communication and for proximity detection a proximity detection signal and a communication signal are supplied through a same feed but in different time frames.

8. The method of claim 5, wherein the components include a reflection lens operating so that so that a light waveform is transmitted through the reflection lens from a door plate and light is reflected from a door frame through the lends to a sensor which measures for each wave light transition a time of light in comparison to a time of light when the sensor was calibrated, to thusly identify whether a door is open or closed, and the lens provides spinning of an optical sensor wave by 45 degrees.
