    [0031] The present invention, in one exemplary embodiment, is a novel vibrating bed configuration. The vibrating bed configuration features a skeleton structure with an integrating vibrating system. The vibrating system includes a vibration motor attached to the bottom surface of the skeleton structure, a USB box coupled to the vibration motor, the USB box storing a processor, a wireless module, a weight sensor and a speaker, and a plurality of rubber tubes disposed on the bottom surface of the skeleton structure. The vibration motor is configured to vibrate and shake the rubber tubes to shake the skeleton structure wherein the vibration motor is automatically activated when the processor receives a wireless signal from a room, home, or building fire/smoke detector for smoke or fire detected by the room, home, or building fire/smoke detector.

    [0032] Referring initially to the drawings, FIG. 1 illustrates a schematic view of one potential embodiment of a fire and smoke alert system of the present invention in accordance with the disclosed architecture. FIG. 1 shows several advantageous features of the present invention, but as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The fire and smoke alert system 100 is designed using a novel vibrating bed 102 that can be in wireless communication with a room, home, or building fire or smoke alarm device 104 mounted at any appropriate place in the room where the vibrating bed 102 is placed. The bed 102 and the alarm device 104 are in wireless communication using a wireless communication channel 106, preferably Bluetooth. The vibrating bed 102 is configured to vibrate instantly to wake people sleeping on the bed 102 when the fire or smoke alarm device 104 detects fire or smoke. A wireless signal from the room, home, or building alarm device 104 is transmitted to the bed 102 when the smoke or fire is detected and that allows the bed 102 to vibrate to wake up the user. The wireless channel 106 can be of any local area network (LAN), metropolitan area network (MAN), wide area network (WAN), a public data network (e.g., the Internet), short range wireless network and the like, or any combination thereof. In addition, the wireless network can be, for example, a cellular network and may employ various technologies including enhanced data rates for global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., worldwide interoperability for microwave access (WiMAX), Long Term Evolution (LTE) networks, code division multiple access (CDMA), wideband code division multiple access (WCDMA), wireless fidelity (WiFi), wireless LAN (WLAN), Bluetooth®, mobile ad-hoc network (MANET) and the like, or any combination thereof.

    [0033] More specifically, the vibrating bed 102 includes a vibrating motor 108 that is disposed at a convenient location of the bed, preferably at the bottom surface of the skeleton structure 114 of the bed 102 as shown in FIG. 3. The vibrating motor 108 is activated when the processor 112 of the bed 102 received the wireless or alarm signal from the room, home or building fire alarm 104 and provides power to the vibrating rubber tubes 110 that are disposed throughout the bottom surface of the bed 102. The vibrating rubber tubes are configured to vibrate to create a sensation in and through the mattress to the users lying on the bed 102. The processor 112 is designed to control and operate the vibrating motor 108 and increase the vibrating frequency of the rubber tubes 110 in case the users lying on the bed 102 do not wake up and get off of the mattress when fire or smoke is detected as described best in FIG. 6. In addition to providing vibration for waking up the users, the bed 102 includes an integrated speaker 120 that produces an alarming sound when the fire or smoke wireless signal is received by the processor 112 from the alarm device 104.

    [0034] For providing wireless communication capabilities to the vibration bed 102, a wireless module 116 is integrated. The wireless module 116 is used for establishing the wireless communication channel 106 between the bed 102 and the alarm device 104. According to embodiments of the present invention, the wireless module 116 can be in the form of an integrated chip and can be, but not limited to, a Bluetooth chip, a Wireless Fidelity (Wi-Fi) chip, an Infrared (IR) chip, Global System for Mobile Communication (GSM) chip, a Code-Division Multiple Access (CDMA) chip, a Near Field Communication (NFC) chip, and so forth. In a preferred embodiment of the present invention, the wireless device 116 is a Bluetooth Low Energy module.

    [0035] For providing vibration only when at least one user is lying on the fire protection bed 102, a weight sensor 118 is disposed at the bottom surface of the bed. The weight sensor 118 can be optionally present in the bed 102 and is utilized to detect any weight on the bed. Further, the weight sensor 118 provides detected weight information to the processor 112 that is used for actuating the vibration motor 108. In situations where a weight is not detected by the weight sensor 118 on the bed, then it can be deduced that a user is not lying or sleeping on the fire protection bed 102 and thus vibration is not actuated. In this case, only speaker 120 can be activated to produce an alarming sound. It should be appreciated that the weight sensor 118 is an optional feature of the system and can be removed based on the preferences and desires of users. For manually deactivating the vibration motor 108, an actuation button is disposed on the bed 102 and can be pushed to deactivate the motor 108, based on the preferences of the users.

    [0036] In use, the vibrating motor 108 shakes the rubber tubes 110 that shake the bed and the user(s) lying on the bed 102 in order to wake them up. For providing power to the motor 108, a power supply 124 is disposed in the bed 102. The power supply 124 can have a power cord that plugs into a conventional 120-volt AC power outlet, as is conventional in homes and other areas. Although, in the disclosure only one vibrating motor 108 is shown and described, it is to be appreciated that more than one motor can be used for providing vibration to the rubber tubes depending on the bed size and the power of vibration required by users.

    [0037] It is to be appreciated that the vibrating motor 108, the vibrating rubber tubes 110, the processor 112, the wireless module 116, the weight sensor 118, the speaker 120 and the actuation button 122 are connected to each other through a wired circuit on the surface of the bed 102. Further, the processor 112, the wireless module 116, the weight sensor 118, and the speaker 120 can be formed as a single physical unit that houses these components. The components forming the vibrating bed 102 can be retrofitted to any existing bed or can be attached to a bed during manufacturing of the bed, thereby ensuring that users can quickly escape a dangerous situation due to fire or smoke.

    [0038] FIG. 2 illustrates a block diagram showing components of an exemplary fire and smoke alarm device 104 that is used in conjunction with the fire protection bed 102 of the present invention in accordance with the disclosed architecture. The fire and smoke detection and alarm device 104 can be an ionization detector or a photoelectric detector. The bed 102 can work with any type of fire and smoke detector 104. The alarm device 104 includes a fire detector 202 that detects fire by sensing small particles in the air. The fire detector component 202 can detect both slow-burning “smoldering” fires and fast-burning “flaming” fires. A smoke detector component 204 detects the smoke and the sensitivity of the smoke detection can be customized for effective protection from dangerous smoke and fire. A processor 206 of the alarm device 104 transmits a wireless signal to the bed 102 as shown in FIG. 1 when fire or smoke is detected by the alarm device 104 using the Bluetooth module 208. The Bluetooth module 208 establishes the wireless channel with the wireless module of the bed 102, thereby allowing transmission of the wireless signal from the processor 206. The alarm device 104 can have a speaker 210 for producing a sound for alerting the users in the room and in other surrounding areas indicating smoke or fire. For providing a visual alert, LEDs 212 are disposed on the fire alarm device 104 that can be flashed in a specific color such as “RED”, for example to indicate that a dangerous smoke or fire is detected by the device 104.

    [0039] It should be appreciated that in one embodiment of the present invention, the fire and smoke alarm device 104 and the fire protection bed 102 come together in the form of a kit. Alternatively, the fire protection bed 102 can be paired with any conventional fire and smoke alarm device 104 wherein the fire and smoke alarm device 104 includes a wireless communication capability.

    [0040] FIG. 3 illustrates a perspective view showing the fire protection bed 102 being placed in a room 300 and paired with the exemplary smoke and fire detector device 104 for vibrating the bed in accordance with the disclosed architecture. As shown, the vibrating bed 102 is placed on the floor 304 of the room 300 and the fire alarm 104 can be mounted to a wall or ceiling 302 of the room 300. At the bottom surface 1140 of the skeleton structure 114 of the bed 102, a USB box 308 is attached along with the vibrating motor 108. The USB box 308 collectively houses the processor 112, the wireless module 116, the weight sensor 118, and the speaker 120 as described in FIG. 1. The vibrating motor 108 is connected to the rubber tubes 110 that are disposed along the bottom surface 1140. The rubber tubes 120 can be shaken and vibrated by the vibrating motor 108. When the rubber tubes 110 are shaken, the mattress 310 placed on the bed 102 is shaken and vibrated and thus user(s) lying on the mattress 310 wake up instantly. In operation, when fire or smoke 306 is detected by the detector device 104, a wireless signal is transmitted to the processor 112 placed inside the USB box 308. The wireless signal is an indication that fire or smoke 306 is detected and accordingly, the processor 112 of the bed 102 actuates the motor 108 to shake and vibrate the rubber tubes 110.

    [0041] The vibrating motor 108 is preferably in the form of a mini-motor that can have a weight in the range of about 0.5 kg to about 1 kg and vibrates at least in the range 10,000 rpm-15,000 rpm. The rubber tubes 110 directly shake and vibrate the mattress 310.

    [0042] FIG. 4 illustrates a bottom perspective view of the fire protection bed 102 showing a position of the USB box 308, vibrating motor 108, and the rubber tubes 110 on the bottom surface 1140 of the bed 102 in accordance with the disclosed architecture. The vibrating system comprising the USB box 308, vibrating motor 108, and the rubber tubes 110 is preferably disposed to the bottom surface 1140 of the bed 102 with a wired circuit (not shown) connecting these components. In one embodiment, more than one vibrating motor can be disposed and connected to the rubber tubes 110 to shake and vibrate the bed 102. As shown, the rubber tubes 110 are distributed along the bottom surface 1140 and vibrate by receiving power from the vibrating motor 108. The USB box 308 is detachably-placed on the bottom surface 1140 and can be positioned to receive wireless signals from the fire and smoke alarm device 104.

    [0043] FIG. 5 illustrates a flow diagram showing exemplary steps in generating vibration in the vibrating bed for waking up user(s) lying on the bed in accordance with the disclosed architecture. Initially, the fire and smoke alarm 104 and the vibrating bed 102 are paired or connected together using the wireless communication channel such as Bluetooth (Block 502). Then, smoke or fire is sensed by the fire and smoke alarm (Block 504) and when the fire or smoke is detected by the alarm device, a wireless alert signal is transmitted from the fire or smoke alarm to the vibrating bed (Block 506). The weight sensor detects the weight (such as of a user) on the bed (Block 508) and if weight is detected, then the process moves to Block 512 where the vibration motor starts shaking and vibrating the rubber tubes to vibrate the user for waking. In case the weight is not detected by the weight sensor, then, the vibration motor is not activated (Block 510).

    [0044] FIG. 6 illustrates a flow diagram showing steps performed in increasing the frequency of vibration produced by the vibrating motor used in the vibrating bed 102 of the present invention in accordance with the disclosed architecture. As shown, initially the vibration motor starts vibrating the rubber tubes (Block 602) and a time value is detected for which the vibration has been performed wherein the vibration time is also compared to a preconfigured threshold (Block 604). Then, weight on the bed is checked (Block 606) and in case the weight is detected, vibrations produced by the vibration motor in the rubber tubes are increased (Block 608) and in case weight is not detected, then, the vibrations are stopped (Block 610).

    [0045] By using weight determination or detection, the method detects if a person is still lying on the bed even after the bed has been vibrated for a predetermined time period due to smoke/fire detection. In case a person is lying on the bed, even after the bed is vibrated for a predetermined time period, the method helps in increasing the vibration level to the bed, and therefore, increases the alarm level to wake up the person and thereby assist in saving the person from residential fire.

    [0046] FIG. 7 illustrates another schematic view of the fire and smoke prevention system of the present invention with the fire protection bed 102 is in communication with an Internet of Things (IoT) hub 702 in accordance with the disclosed architecture. An advantage of the vibrating bed 102 of the present invention is that it can be communicatively coupled with an IoT hub 702 using the wireless module and then can become a part of a smart home or IoT network. The bed 102 can communicate with the IoT network using any local area network (LAN), metropolitan area network (MAN), wide area network (WAN), a public data network (e.g., the Internet), short range wireless network, or any other suitable packet-switched network, such as a commercially owned, proprietary packet-switched network, e.g., a proprietary cable or fiber-optic network, and the like, or any combination thereof. In addition, the wireless network can be, for example, a cellular network and may employ various technologies including enhanced data rates for global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., worldwide interoperability for microwave access (WiMAX), Long Term Evolution (LTE) networks, code division multiple access (CDMA), wideband code division multiple access (WCDMA), wireless fidelity (WiFi), wireless LAN (WLAN), Bluetooth®, Bluetooth low energy (BLE), Internet Protocol (IP) data casting, satellite, mobile ad-hoc network (MANET), and the like, or any combination thereof.

    [0047] The IoT hub 702 is further communicatively coupled to a variety of smart devices such as a smart kitchen appliance 704, the fire/smoke alarm 104, smart door 706 and many more. In case the IoT hub 702 receives an alert signal from any of these smart devices, the IoT hub 702 can transmit a wireless instruction signal to the bed 102 to actuate the vibrating motor and starts vibrating the bed 102. As an example, the smart door 706 can alert the IoT hub 702 in case the door opens during the night, after 1 AM for example. In such a case, the IoT hub 702 can alert the bed 102 to vibrate, thereby causing the user to wake up in order to prevent any burglary. It should be appreciated that direct communication between any of the smart devices and the vibrating bed 102 is also possible in a manner similar to the schematic shown in FIG. 1 of the present invention.
