Window blind with pressure sensor which activates light and sound in sequence
We disclose a window blind that includes a security feature. The disclosed window blind includes a plurality of slats, at least one of which includes a hollow core. The hollow core includes at least one pressure sensor, a controller, and a battery. The pressure sensor detects a change in pressure when an adjacent window or door is opened or broken. The controller may be connected to the pressure sensor and to multiple light fixtures and/or audio speakers throughout the building. Program code in the controller may receive instructions which include a defined order in which the controller sends a signal to each of the light fixtures and audio speakers causing them to actuate.
1. A window blind comprising:
at least two tilt strings;
a plurality of slats, each of the plurality of slats comprising:
two longitudinal sides each longitudinal side comprising a length, and
two transverse sides, each transverse side comprising a width,
wherein the length of each of the plurality of slats is at least five times the width, wherein each of the plurality of slats is mounted on the at least two tilt strings, wherein the plurality of slats performs a tilting movement in response to a movement of the at least two tilt strings thus reversibly moving the plurality of slats between an open position and a closed position, and wherein the two transverse sides of each of the plurality of slats are perpendicular to the at least two tilt strings when the plurality of slats is in an open position;
a hollow core;
an orifice, wherein the orifice leads into the hollow core, and wherein the orifice is positioned along one of the longitudinal sides;
at least one air pressure sensor disposed within the hollow core and positioned to detect a change in pressure in the area adjacent to the orifice;
a battery, wherein the battery is disposed within the hollow core; and
a controller, wherein the controller is disposed within the hollow core, wherein the controller is electronically connected to the at least one pressure sensor, wherein the controller comprises a memory, and wherein the memory comprises program code; and
a data communication device, wherein the data communication device transmits a first signal to a remote device when the at least one pressure sensor detects a change in pressure, and wherein the controller receives input data from the remote device through the data communication device.
2. The window blind of claim 1 , wherein the at least one pressure sensor comprises one or more of the following pressure transducers: a strain gage pressure transducer, variable capacitance pressure transducer, and piezoelectric pressure transducer.
3. The window blind of claim 1 , wherein the controller is electronically connected a plurality of light fixtures, wherein the program code prompts the controller to send a second signal to the plurality of light fixtures through the data communication device to actuate each of the plurality of light fixtures in a first sequence after the controller receives the first signal.
4. The window blind of claim 1 , wherein the input data comprises the first sequence.
5. The window blind of claim 1 , wherein the remote device is a mobile device.
6. The window blind of claim 3 , wherein controller is electronically connected to the at least one pressure sensor and to a plurality of light fixtures through a wireless device.
7. The window blind of claim 6 , wherein the wireless device comprises a Bluetooth device.
8. The window blind of claim 3 , further comprising an audio device, wherein the audio device comprises an audio recording device, and wherein the audio device is electronically connected both to a plurality of audio speakers and to the controller, wherein the program code prompts the controller to send a subsequent signal to the audio device through the data communication device causing the audio device to actuate each of the plurality of audio speakers in a second sequence after the controller receives the first signal.
9. The window blind of claim 8 , wherein the input data comprises the second sequence.
10. The window blind of claim 8 , wherein audio recording device comprises at least one audio recording, wherein the at least one audio recording consists of one or more of the following sounds: a barking dog, a siren, a door opening, the sound of footsteps, and a human voice.
11. The window blind of claim 10 , wherein the human voice is a recording of a user's voice.
12. The window blind of claim 11 , wherein the recording of a user's voice is transmitted to the audio recorder through the remote device.
13. The window blind of claim 8 , wherein the audio device is wirelessly connected to the plurality of audio speakers.
14. The window blind of claim 13 , wherein the audio device is wirelessly connected to the plurality of audio speakers through a Bluetooth device.
15. The window blind of claim 1 , further comprising an audio device, wherein the audio device comprises an audio recording device, wherein the audio device is electronically connected both to a plurality of audio speakers and to the controller, and wherein the program code prompts the controller to send a subsequent signal to the audio device through the data communication device causing the audio device to actuate each of the plurality of audio speakers in a defined sequence after the controller receives the first signal.
16. The window blind of claim 15 , wherein the input data comprises the defined sequence.
17. The window blind of claim 15 wherein audio recording device comprises at least one audio recording, wherein the at least one audio recording consists of one or more of the following sounds: a barking dog, a siren, a door opening, the sound of footsteps, and a human voice.
18. The window blind of claim 17 , wherein the human voice is a recording of a user's voice.
19. The window blind of claim 15 , wherein the audio device is wirelessly connected to the plurality of speakers.
20. The window blind of claim 19 , wherein the audio device is wirelessly connected to the plurality of speakers through a Bluetooth device.
