In some examples, outer pieces 406 and 428 may comprise one or more solar panels configured to serve as a recharging mechanism to battery 414. In some examples, the solar panel may receive ambient or room level light and recharge battery 414. This allows for battery 414 and safety device 400 to function for prolonged periods of time without requiring manual recharging. In another example, the recharging mechanism may comprise a wireless recharging mechanism, such as inductive charging (e.g. the Qi standard). In some examples, the safety device 400 may also comprise a shaker motor to provide haptic or tactile feedback for example when the capacitive touch button is engaged. For example, if a user touches touch sensor 412 the shaker motor may provide tactile feedback by shaking enough to indicate to a user that the safety device 400 has registered the touch. For example, the touch sensor 412 may receive a touch from a user and send a signal to controller 462 that receives the signal from the touch sensor 412 and sends a control signal to the shaker motor to provide the tactile feedback. In a similar manner the safety device 400 may also comprise a speaker for providing auditory feedback, such as in the same way as, and/or at the same time the device provides tactile feedback. For example, the speaker may emit a sound while the shaker motor shakes.
In some examples, the touch sensor 412 may comprise multiple segments or a dividing mesh such that the touch sensor 412 comprises multiple touch areas that may function as multiple buttons. For example, the touch sensor 412 may be divided into four areas such that the user may interact with four buttons. The buttons of the touch sensor 412 may be utilized for differentiated input, such as an input for a timer including resetting/restarting the timer or selecting a timer period or expiration time for the timer. For example, a user may select from a selection of five minute increments such as five, ten, fifteen, or twenty minute increment for the expiration time. The buttons of the touch sensor 412 may also be utilized in entering or leaving a child lock mode of the device. For example, a user may enter in a series of touches on the buttons to enter into (engage) a child lock mode and may also enter the same or a different series of touches to leave (disengage) a child lock mode.
The controller 462 may be also programmable to actuate the electric motor 454 to rotate the safety device 400 and, thus, the operational shaft 38 to the Off position upon the receipt of a signal such as a hazard detected signal indicating the occurrence of a safety event. In some examples, the Off position is determined as the position where the operational shaft may not be turned further in a clockwise or counterclockwise position. This may be indicated as when the motor 464 stalls or cannot turn the operational shaft any further such as indicated by a voltage spike from the motor and measure by controller 462.
In some example embodiments, safety device 400 may also include a gyroscope and accelerometer which are used in combination with controller 462 to provide a position sensing function which indicates the position of the safety device 400. In some examples, the Off position may be recorded or set during an initial set-up or calibration of the device (such as the process using user device 1306 described herein). In some examples, safety device 400 also comprises a switch 474 (
Furthermore, in the same manner as the safety device 20, the safety device 400 may also be configured to selectively automatically shut off the flow of electricity or gas to a burner, such as burner 40, under certain predetermined safety conditions. The safety device 400 may also be regulated by a motion sensor, which may be positioned on the device or remote from the device, such as in a sensor/relay device which monitors the presence of a user near the stove to determine whether or not to activate the powered shut-off mechanism. The system may track the time duration of absences of a user via the motion sensor. If no movement is detected within a predetermined period, the safety device 400 may be automatically activated to turn the operational shaft 38 to the Off position. In the event that the motion sensor of the safety device 400 fails or communication with a sensor/relay device also fails, the timer may be reset by a user input, such as a user touching the touch sensor 412 and/or overriding automatic shut-off due to absence of a user. This provides a failsafe mode for the safety device 400 in an instance where the safety device 400 has lost communication abilities with a sensor/relay device, such as a remote motion sensor. This arrangement also allows full control of the operational shaft 38 of a burner, such as the burner 40. For example, the safety device 400 may be configured to move the operational shaft 38 of the burner 40 to multiple On positions.

Referring back to safety device 20 and to
The two-piece adaptor 33 and 34 comprises an inner set-screw portion 33 and an outer universal adaptor portion 34. The inner set-screw portion 33 defines a bore 64 for receiving the operational shaft 38 for the burner 40. A set-screw extends through a threaded hole in the set-screw portion 33 and into the bore 64. The set-screw engages the operational shaft 38 for securing the inner set-screw portion 33 of the two-piece adaptor to the operational shaft 38. The outer surface of the set-screw adaptor has a longitudinal key 66. As shown in
The outer universal adaptor portion 34 is a hollow tubular member configured to be secured at an outer end of the control knob 36. The universal adaptor portion 34 enables the safety device 20 to be used universally compatible with control knobs of many designs and configurations. The universal adaptor portion 34 defines a bore with a contiguous longitudinal slot. The shape of the bore and the slot corresponds to the periphery of the inner set-screw portion 33 such that the key 66 is received in the slot in the universal adaptor portion 34. Thus, the adaptor portions are keyed for rotation together along with the concentricity gear 54.
The control knob 36 is secured to, or engaged with, an operational shaft 38 of the burner 40 for controlling power supply used to operate the burner 40. The control knob 36 may be used to manually operate the burner 40. In other words, the control knob 36 is configured to move as a rotary dial in a manner substantially similar to a traditional stove knob for rotating the operational shaft 38 to activate the associated burner. As shown in
In use, the safety device 20 is configured to be received on an operational shaft 38 of a stove or other appliance. A user may retrofit an existing stove by removing an existing knob from a respective stove burner operational shaft and inserting the safety device 20 thereon. As described above, the base member 24 may be adhesively adhered to the surface of the stove surrounding the operational shaft 38. When cooking is desired, the control knob 36 of the safety device 20 is manually rotated in a traditional manner for controlling an output of power from the stove to activate the burner 40. As shown in
Signals may be sent to and from the sensors using wired or wireless signals, such as data signals or messages. As shown in
In operation, the output of the sensors is continuously monitored. In one example, the one or more sensors, such as sensors 1304a-1304c generate one or more monitoring signals which are transmitted to a processor, such as sensor controller 1304d. In some examples, the processor receives the one or more monitoring signals and generates one or more control signals and causes the communication unit 1304e to transmit the one or more control signals to a controller, such as device controller 1302c, which in turn controls a motor, such as motor 1302f. In some examples, the control signals sent between the device controller 1302c and the motor 1302f are Pulse-width modulation (PWM) signals. The controller, such as device controller 1302c communicates with the sensor/relay module 1304 and sensor controller 1304d, which processes data received from the sensors to selectively transmit command data to a motor 1302f, which may comprise a motor in any of the safety devices described herein. The controller includes a processor having programming for operating the safety device module 1302 and functions substantially as described herein. In some examples, the device controller 1302c receives the sensor signals, determines appropriate command/control signals, and transmits the command/control signals either through a wired or wireless interconnection to the motor 1302f. A safety event is detected when a level of any of the sensors 1304a-1304c is detected that exceeds predetermined thresholds by either sensor controller 1304d or device controller 1302c, the controller, under the control of the system software contained within it, sends a control signal to the motor. The motor automatically drives the safety device module 1302 to turn off a burner by rotating the operational shaft of the burner.
Control of the safety device module 1302 may also be communicated by the user through user interface components as part of the safety device module. The interface components that may be a part of the safety device module 1302 as shown in
The system 1300a may further include a selectable timer. The timer may be automatically activated and in two-way communication with a controller 1304c and 1302d. In some examples, the timer will remind the user after a predetermined time that the burner is still activated. In some examples, a speaker may be situated on a printed circuit board and in electrical contact with a controller and the timer. After a predetermined time, the controller in communication with the timer actuates the speaker to emit a sound, such as a chime, for reminding a user to monitor the status of the cooking that was previously initiated. The motion sensor 1304c may also function with a timer. The motion sensor 1304c can have a variable placement location and peripheral view to detect the presence of a user in a predetermined proximity of the burner and can employ different types of sensing mechanism, such as infrared, ultrasound, optical, or weight-sensing switches. After a burner has been turned on, the motion sensor 1304c continuously monitors the presence of a user near the burner. If a user presence is detected, the timer of the safety device module 1302 is bypassed or restarted and power flows to the burner uninterrupted. The safety device module 1302 timer may turn the operational shaft of the burner to an Off position if no user is present and the time since the last user presence is less than a predetermined time. The predetermined time may be reset each time a user presence is detected. However, if no user presence is detected and the predetermined time has elapsed, the controller transmits a command signal to the motor 1302f to turn off the burner. In some examples, motion detector 1304c and sensor controller 1304d are configured to determine if motion detected is human motion. For example, motion sensor 1304c and controller 1304d may be configured to filter out motion caused by inanimate objects, such as shifting light, or things such as pets. For example, motion sensor 1304c and sensor controller 1304d may be configured to detect that sensed motion is from a dog or cat and thus non-human presence has been detected, which may be 3 disregarded or ignored.
In another example, the timer of the safety device module 1302 may be bypassed or restarted by a user utilizing a touch button of the safety device module 1302 or by utilizing a user interface of user device 1306.
As illustrated, each of the safety device module 1302, sensor/relay module 1304, and user device 1306 may be in communication with each other such as through low energy Bluetooth, Wi-Fi, near-field communication (NFC), radio frequency (Rf), or infrared communication among others. The sensor/relay module 1304 may be configured to operate with a plurality of the safety device modules 1302 such as a plurality of safety device modules operating a plurality of burners on a stove top. Similarly, sensor/relay module 1304 may also be in communication with multiple user devices 1306. For example, multiple members of the same household may each use a user device 1306 to communicate with sensor/relay module 1304 and safety device module 1302. In some examples, user device 1306 may connect through a network connection such as an internet or Wi-Fi connection to sensor/relay module 1304 and the sensor/relay module 1304, may connect with safety device module 1302 through low energy Bluetooth, such that communication of system 1300b may use different communication protocols.
In some examples, the user device 1306 may also comprise a Global Positioning System (GPS), such that if the user device leaves a location of the safety device module 1302, the sensor/relay module 1304 and/or the safety device module 1302 may determine that a burner is in an On position representing a hazard detected or safety event. For example, is a user forgets to turn of the burner and leaves their home sensor/relay module 1304 may detect that the user device 1306 is remote from the home and generate a hazard detected signal. In some examples, a user may utilize the user device 1306 interface described herein to override the remote location detection hazard signal in the event that they are aware the burner is still on and would like to leave it on while not in the home.
In some examples, the safety device module 1302 may be embedded into a stove with digital controls such that turning an operation shaft of a burner is not required to turn off power to the burner. In this case, the control signal from the sensor/relay module may indicate to a controller of the safety device to cease providing power by sending a power off signal to a burner control module.
In some examples, a plurality of safety device modules 1302 may be preprogrammed to communicate with a specific sensor/relay module 1304, such that when the modules are powered on they automatically discover and communicate with each other. In other examples, each of a plurality of safety device modules 1302 may enter into a discoverable mode once powered such that a user utilizing user device 1306 and sensor/relay device 1304 may detect the discoverable safety device modules and pair or connect (add) them into the system 1300b. This allows for multiple safety device modules to be connected or replaced at different times.
As shown, the system 1300b may comprise additional safety features to operate safety device module 1302. For example, a child lock or burner use lock may be implemented in system 1300b. A child lock may be implemented to prevent an operational shaft of a burner from being turned to an On position. In some examples, the child lock may include a mechanical lock that prevents a safety device module from being turned from the Off position to an On position.
In one example of the child lock as implement in a safety device module utilizing the safety device 400, the safety device 400 may include an additional child lock member between fixed base member 424 and motor member 420 which may be locked by controller 462 when a child lock has been engaged. A mechanical lock may also be an external piece that may be manually position by a user between the safety device 400 and the stove top. The child lock member may be configured to prevent the engagement of the operational shaft 38 by the motor member 420 preventing the rotation of the safety device 400. In other examples, the controller 462 may include software to automatically turn the operational shaft 38 to an Off position, preventing the burner 40 from being turned on continuously. For example, a child may manually turn the safety device 400 to an On position, but if the child lock is engaged, the safety device 400 will automatically rotate the operational shaft 38 back to the Off position. Other examples, of a child lock may include locking the electric motor 454 and/or gear train 452. Child lock functions may be engaged using a user interface at the user device 1306 or utilizing user interface components, such as a capacitive touch sensor, at safety device module 1302.
In some example embodiments, the safety device module 1302 may be configured to operate between an appliance 1308 and a power source 1310 as illustrated by example system 1300c in

In another example embodiment of system 1300d, a cooking device such as cooking device 1312 may be configured to directly monitor cooking properties, such as temperature, of food or a cooking environment 1314 during the process of cooking food utilizing a burner under operational control of safety device module 1302. The cooking environment 1314 may include a pot, a pan, or any other types of cookware that may use a burner during the cooking process. For example, sous vide is a style of cooking which requires accurate and regulated temperatures of water/steam for long periods of time to properly cook food in this style. Thus, cooking device 1312 may include a thermometer for monitoring the temperature of water/steam in the cooking environment 1314 and may generate a control signal that is used to modulate the power supplied to a burner providing heat to the cooking environment such that a constant regulated temperature is supplied. The control signal may be supplied directly to the safety device module 1302 to modulate the power supplied to the burner or may be sent through sensor/relay module 1304 to safety device module 1302. In another example, cooking device 1312 may include other sensors such as a camera to monitor visual cooking properties, such as color or perceived doneness, of food in the cooking environment 1314, or of the cooking environment 1314, such as the melting of butter or boiling of water. In each of these examples, the cooking device 1312 may include a processor and communication modules in communication with sensor/relay module 1304 and/or safety device module 1302 to control the power supplied to a burner and thus the amount of heat in the cooking environment 1314.
The sensor/relay device 1400 may comprise a housing member 1418, a top piece 1402, and an LED array 1404. The housing member 1418, the top piece 1402, and the LED array 1404 may be attached to base pieces 1410 and 1416 to provide an enclosed sensor/relay device as shown in

The knob 36 defines a bore 37 for receiving the spaced distal ends of the arms 133, 134 in a friction-fit relationship. The distance between the arms 133, 134 is adjustable for accommodating different sizes of stove knobs 36. The universal adaptor 110 thus enables the safety device 100 to be used universally compatible with control knobs of many designs and configurations. The control knob 36 is secured to, or engaged with, the operational shaft 38 of the burner 40 through the core unit 108 for controlling power supply used to operate the burner. The control knob may be used to manually operate the burner 40. In other words, the control knob 36 is configured to move as a rotary dial in a manner substantially similar to a traditional stove knob for rotating the operational shaft 38 to activate the associated burner.
In use, the safety device 100 is configured to be received on an operational shaft 38 of the stove or other appliance. A user may retrofit an existing stove by removing an existing knob 36 from a respective stove burner operational shaft and inserting the safety device 100 thereon and then reinserting the knob 36 on the universal adaptor 110. As described above, the base member 104 may be adhesively adhered to the surface of the stove surrounding the operational shaft 38. When cooking is desired, the control knob 36 of the safety device 100 is manually rotated in a traditional manner for controlling an output of power from the stove to activate the burner 40. Upon the occurrence of a safety event, the safety device 100 automatically rotates the control knob 36 to an Off position. More specifically, the motor 106 is started and turns the core unit 108 through the stem 124 which, in turn, rotates the control knob 36 and the operational shaft 38.

Example embodiments of rendered user interface components are shown in
Component 2708 represents a highest On position of the operational shaft of the burner, and component 2712 represents a lowest On position of the operational shaft of the burner. Component 2710 represents an Off position of the operation shaft of the burner. In some examples, the user device 1306 may be used to set varying positions of the safety device module during an initial set-up or a calibration of the varying positions. For example, user interface 2702 may include instructions for a user to turn the safety device module to a highest On position such that the operational shaft of the burner is in a highest On position and providing the maximum amount of power (electricity or gas) to the burner. The user may then select that the safety device module 1302 is in the highest On position. User device 1306 may then send a confirmation signal to safety device module 1302 to confirm that the device is in the highest On position. The position may then be stored at controller 1302c for future use by the safety device module. The same process may be used to position the lowest On position, as well as, any number of a plurality of other On positions, such as a medium low position, a medium position, a medium high position, etc., as well as the Off position. Each of the positions may be stored at controller 1302c such that when a control signal is received from user device 1306, the controller may then access the stored position and issue a control signal to the motor such that the operational shaft of the motor will be instructed to turn to the stored position.
Component 2728 represents a user selection of safety device modules each controlling one of a plurality of burners including safety device modules 2728 and 2728a-c. Each of the burners in the plurality of burners may be associated with a safety device module, such as safety device module 1302. A user may be able to independently control the position of each safety device module of the plurality of safety device modules using user device 1306. Components 2720, 2722, 2724, and 2726 may be configured to show other user interfaces corresponding to a presentation of status information of a sensor module such as sensor module 1304, the status of a home, and/or a historical view of the status of the system such as system 1300b. For example, component 2720 may be selected for user interface components related to one or more safety device modules. Component 2722 may be selected for user interface components related to one or more sensor/relay devices. Component 2724 may be selected for user interface components related to one or more elements of a home. Component 2726 may be selected for user interface components related to historical data of the one or more safety device modules, the one or more sensor/relay devices, the home, the user interface components, the user interface, or the user computing device itself. Element 2706 provides access to a settings menu which may allow a user to adjust settings of the user interface, such as an application running on the user computing device 1306 and may also provide support information to the user. Element 2706 may also provide access and management of user account information such as a user name and device information with external server 1320.
In some examples, user device 1306 may receive a notification from safety device module 1302 and/or sensor/relay module 1304 indicating the occurrence of a safety event. In some examples, a user may be able to override the safety device module from turning to the Off position. For example, if a timer has elapsed as described herein, safety device module and/or sensor/relay module 1304 may send a notification with a temporal option to cancel the safety device module 1302 turning to the Off position. The user may also be able to override or temporarily turn one or more of the sensors in the sensor/relay module 1304 off. For example, if a user is cooking and producing large amounts of smoke, but knows there is no fire, the user may utilize user device 1306 to temporality turn off a smoke sensor in the sensor/relay device.
Additionally, user device 1306 may also be configured to allow a user to add multiple authorized users and/or user accounts to control safety device module 1302 and receive device status indications including notifications.

The control signal may be an off signal such that the motor that is connected to an operational shaft of a burner through a gear train turns the operation shaft of the burner to an Off position. In some examples, the timer may be kept at sensor/relay module 1304 wherein controller 1304d performs the operation described above and sends the control signal to controller 1302c.
