Patent Application
20240271476
The present application is directed to a system for remote opening and closing of a door or window, and more particularly, to a smart window/door system that (1) can easily be retrofitted for use with an existing door or window or can be built-in by the door or window manufacturer, (2) can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet and/or (c) automatically by a voice command, (3) is disengaged when use is not desired, (4) provides safety and security to prevent unwanted opening or closing of the door or window, and (5) is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.
In modern life, there are a number of trends, including more and more families having (1) two working adults, (2) pets that are home alone during major portions of the day and (3) package deliveries for online purchases while no one is home. These trends give rise to a number of safety and security concerns.
Pets often need access to outside spaces, such as the backyard, to exercise and/or relieve themselves when no one is home. One known approach is to leave a door or window, such as a sliding patio door, at least partially open, so the pet can freely exit from and enter into the residence. The drawback to this approach is unwanted intruders, including unwanted animals, bugs, flies or people can also enter the residence. Also, depending on the weather and/or season, leaving a door or window open all day long may be impractical, especially during rainy or windy conditions, or during the winter or summer months when the outside temperature is either cold or hot and/or humid. A so called “doggie” door is a known alternative to leaving a door or window open. With a doggie door, a trained pet can exit and enter the residence when they wish. The drawback with doggie doors is that they are expensive to install, requiring structural modifications (i.e., cut a hole, replace a pane, etc.) to either a wall or a door, do not prevent other unwanted animals from entering the residence, can potentially be used by an intruder to gain access into the residence, and typically provide poor weather performance (e.g., may leak in the rain, allow hot or cold air into the residence, etc.,)
Packages delivered by carriers such as UPS, FedEx or US Postal are typically left at the door if no one is home, often in plain sight and unsecured. These packages are sometimes stolen by a passerby, or worse, by unscrupulous people who follow delivery trucks and then steal the delivered packages left at a door.
A smart window/door system that can be opened and closed by a pet, or can be remotely opened or closed by those living in a residence to allow egress and ingress by pets or the delivery of packages inside the residence, is therefore needed.
A smart window/door opening-closing device that can easily be installed for use with an existing door or window or can be built-in by the door or window manufacturer, can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet and/or (c) automatically by a voice command, is easily disengaged when use is not desired, provides safety and security to prevent unwanted opening or closing of the door or window, and is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.
The present application and the advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawings in which:
In the drawings, like reference numerals are sometimes used to designate like structural elements. It should also be appreciated that the depictions in the figures are diagrammatic and not necessarily to scale.
The present application will now be described in detail with reference to a few non-exclusive embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one skilled in the art, that the present discloser may be practiced without some or all of these specific details. In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present disclosure.

The ability to selectively engage or disengage the opening-closing system 12 in the operable or inoperable position by simply rotating to either the horizontal or vertical position offers a number of benefits. Foremost, the occupant(s) of the residence or building in which the opening-closing system 12 is installed can easily move it between the operable and the inoperable position. For instance, when the occupant(s) are present, it may be more convenient for the opening-closing system 12 to be moved to the vertical, inoperable, position. On the other hand, when no one is present, it may be convenient to rotate the actuator 12 to the horizontal, operable, position, so that pets can exit or enter the building, or packages can be delivered inside the building.
It should be noted that although
Referring to
The first base 22 is arranged to attach to the moving portion of the door or window that the opening-closing system 12 is intended to open and close. For instance, as provided in
The base 22 includes a catch 42 for selectively latching the actuator rod 36 and the adaptor 38. With this arrangement, the actuator rod 36 and adaptor 38 can either be positioned horizontally to engage or lifted vertically to disengage the actuator rod 36 and actuator 38 from the catch 42 of the first base 22. In an alternative embodiment, the actuator rod 36 can directly engage and disengage the latch 42 of the base 22 without the use of the adaptor 38. Regardless of the embodiment, the opening-closing system 12 is capable of opening or closing the moving portion of the door or window when engaged and incapable of opening or closing the door or window when disengaged.
In yet another non-exclusive embodiment, the opening-closing system 12 can be supplied with multiple adaptors 38, each having a different length. The actuator rod 36 typically will have a fixed length, which may or may not provide an adequate fit for a particularly sized door or window. With multiple adaptors 38, each of different lengths, the most appropriate can be selected and attached to the end of the actuator rod 36. As a result, in spite of the actuator rod 36 being made with a fixed length, it can be used in cooperation with one of the adaptors 38 to fit a wide variety of different door and/or window sizes.
In various embodiments, the sensor 28 can be a still camera, a video or security camera or a Passive Infrared (PIR) sensor. An optional shutter 30, which either surrounds or is otherwise is positioned adjacent the sensor 28, is a mechanical device that may be provided to control the field of vision of the sensor 28. By either opening or closing the shutter 30, the view of the sensor 28 can be either enlarged or decreased. For instance, if it is preferred that the sensor 28 “see” just the area immediately near the door 14, then shutter is partially shut. On the other hand, if a wider field of view is preferred, then the shutter 30 is opened wider.

In various embodiments, the controller 52 is a microprocessor, microcontroller, programmable logic device such as a Field Programmable Gate Array (FPGA), logic circuitry, an integrated circuit, an Application Specific Integrated Circuit (ASIC) or module, or any combination thereof.
The firmware 62 is implemented in some form of memory or storage, such as but not limited to persistent or non-volatile memory, volatile memory, or a combination thereof. The firmware 62 is generally software or code used to control the operation of the controller 52 in response to the various sensors 54-60. In turn, the controller 52 controls the operation of the actuator motor 32 to rotate the screw 34 and actuator rod 36 to either open or close the sliding pane 20 of the door or window 14.
The ball sensor 54 is essentially a “ball circuit” that includes a small ball within an enclosure that is arranged to roll between a closed-circuit position and an open circuit position. When the opening-closing system 12 is positioned in the horizontal, operable, position, the ball moves within the enclosure to the closed-circuit position. When the opening-closing system 12 is moved to the vertical, inoperable, position, then the ball moves to the open circuit position. With this arrangement, the ball sensor 54 is used to signify to the controller 52 the opening-closing system 12 is in either the operable or inoperable position. When operational, the actuator motor 32 and the controller system 50 and are powered on by a power source (not illustrated), such as batteries or a power cord to a standard wall electrical outlet. When not operational, the actuator motor 32 and the controller system 50 can either be powered off completely or placed in a power saving standby or sleep mode.
The sensor interface 56 is designed to operate in cooperate with the sensor 28 provided on the housing 26. As previously noted, the sensor 28 can be a still camera, a video or security camera or a PIR sensor. The sensor interface 56 thus provides to the controller 52 data indicative of still images, video images and/or infrared signals, depending on the type of sensor 28.
The wireless network interface 58 is provided to enable bi-directional communication between the controller 52 and one or more remote communication device(s) over a wireless network. In various embodiments, as is described in more detail below, the remote communication device(s) may include indoor and/or outdoor security camera(s), a voice-activated personal digital assistant (e.g., Alexa by Google, Amazon Echo, Apple Siri, etc.), an application running on a computing device (e.g., smart phone, tablet computer, laptop or desktop computer, etc.), or an identifier tag (e.g., RFID or Bluetooth) attached to or associated with a pet.
The IoT interface 60 module enables the opening-closing system 12, and in particular the controller 52, to be connected as a “Thing” among the IoT. With the IoT interface module 60 receiving signals and commands interpreted by the firmware, the firmware then imposes open and close commands through the controller 52, which in turn, controls the actuator motor 32 to open or close the door. Thus, the IoT interface module 60 can communicate and interact over the Internet with the aforementioned remote devices and be remotely monitored and controlled. As is well understood in the art, the wireless network interface 58 and the IoT interface module 60 can be integrated together into a single interface. In a non-exclusive example, an integrated commercially available wireless network interface 58 and IoT interface module 60 is the Imp 004 offered by a company called Electric Imp, Los Altos, CA.

The remote monitoring and control of the opening-closing system 12 to either open or close the sliding pane 20 of the door 14 may be implemented in a number of ways. For instance:
(1) A pet may wander into the field of vision of the sensor 28. In response, the controller 52 generates a notice, for example in the form of a text message, that is sent via the wireless network 71 to the mobile phone 78 of a designated person, such the pet owner and/or resident of the home. In response, the person can send a reply command back to the opening-closing system 12, instructing the controller 52 to activate the actuator motor 32 to open the sliding pane 20 of door 14, letting the pet out of the residence.
(2) In other examples, the indoor camera 72 may recognize and/or the ID tag 80 worn by a pet may identify the pet near the inside of the door 14. If the controller 52 has been so instructed by commands processed by the firmware, then the controller 52 can automatically activate the actuator motor 32 to open the door 14, letting the pet out. Conversely, when the outdoor camera and/or ID tag 80 recognizes the pet near the outside of the door, then the controller can automatically activate the motor 32 to open the door again to let the pet inside.
(3) In a variation of the above example, the camera(s) 72, 74 and/or the ID tag 80 are used to recognize or identify a pet near the door. Instead of the controller 52 automatically opening or closing the door 14, a text message is sent to the mobile phone 78 of one or more designated person(s). In response, one of the designated person(s) can generate a command to either open the sliding pane 20 of the door 14 or maintain it closed, which is delivered to the controller 52 via the wireless network 71.
(4) The personal assistant 76 may also be used to either open or close the door 14. For example, consider the situation where the door 14 is a sliding patio door adjacent a kitchen. While a person is washing dishes or is otherwise preoccupied, the family pet wanders by the door 14 indicating a desire to go out into the backyard. In response to an “open door” voice command, the personal assistant 76 issues and sends over the wireless network 71 an electronic command to the controller 52, which in turn, activates the actuator motor 32 to open the sliding pane 20 of door 14, allowing the pet out. Similarly, when the pet indicates a desired to be let back in, an “open door” voice command is spoken to the personal assistant 76. In turn, the personal assistant 76 sends an electric command to the controller 52, which in response, opens the door to allow the pet back into the house.
(5) In certain circumstances, the controller 52 can be programmed to not open or close the door in response to the identification of a particular pet, regardless of how identified (e.g., by either camera 72, 74 and/or identifier tag, etc.). For instance, a family may have both a dog and a cat. The controller 52 may be preset or programmed to give the dog in/out privileges, but not the cat. Whenever the cat is identified near the door 14, the controller 52 will not open the door 14. On the other hand, when the dog is identified, the controller 52 will automatically open the door.
There are several issues or concerns involved with the operation of the opening-closing system 12.
One such concern is the detection of some type of obstruction along the track 16, such as a sleeping pet or a baby crawling through the doorway, etc. When there is an obstruction, then the opening-closing system 12 is preferably instructed to stop the closing of the door to prevent entrapment and/or injury.
Another issue is that over time, the mechanical force needed to open or close a given door or window will typically change for a number of reasons, such as wear and tear, a lack of lubrication of the opening/closing mechanism, changes in temperature during the course of a day (e.g., cold at night, warmer during the day), changes in temperature depending on the season of the year (e.g., cold in winter, warm in summer) or changes in humidity, etc.
The opening-closing system 12 is, in non-exclusive embodiments, tasked with differentiating between an actual obstruction and the door or window becoming increasingly more difficult to open or close due to wear and tear and/or the other operating conditions discussed above. If an actual obstruction exists, then the opening or closing of the door should be stopped. On the other hand if more force is required to open or close the door due to other circumstances, then the opening or closing of the door is typically continued.
The opening-closing system 12 may determine if an obstruction exists in a number of different ways. For example: (1) detecting an unusual spike in current or other electrical parameter of the actuator motor 32; (2) defining or setting a maximum force for the actuator motor 32 and stopping the opening or closing of the door or window if the force is exceeded, (3) using an electrical or mechanical fuse that is preset to “blow” if a predetermined electrical parameter or mechanical force is exceeded and/or (4) using one or more of the sensors 28 and/or cameras 72, 74 to detect the obstruction and/or motion within the opening of the door or window.
Referring to
In an initial step 102, the opening-closing system 12 is installed in a door or window 14. In different embodiments, installation may mean either the opening-closing system 12 has been retro-fitted into an existing door or window or it can be installed in a factory when the door and/or window is made (as further described below).
In step 104, the opening-closing system 12 “learns” an electronic signature of the actuator motor 32 for opening and closing the door or window. The electronic signature is learned by performing one or more trial runs of opening and/or closing the door or window. Specifically, the electronic signature is learned during the trial runs by:
(a) Measuring an electric parameter of the actuator motor 32, such as the amount of current used, at discrete distance intervals (e.g., every ¼ or ½ of an inch) of travel of the actuator rod 36 during the trial opening(s) and/or closing(s) of the door or window; and
(b) Averaging the measured electric parameter values for each of the measured discrete distance intervals over the several trial runs.
In the example provided above, the measured electrical parameter of the actuator motor 32 is current and the distance between each of the discrete intervals is ¼ of an inch. It should be understood, however, that neither of these is a strict requirement and that other electrical parameters (e.g., voltage, resistance, inductance, or a combination thereof, etc.) can be used and the distance between measurement points can widely vary as well and be smaller or larger than ¼ inch intervals (e.g., ⅛, ¾, 1 of an inch, etc). Once the electronic signature is learned, it is stored in a location accessible by the opening-closing system 12.
In step 106, the controller 52 receives an actual command (i.e., a non-trial command) to either open or close the door or window 14. In various embodiments, the command may be derived by any of the methods or procedures as described above.
In step 108, the controller 52 controls the operation of the actuator motor 32 to turn the screw 34 either in (1) a first rotational direction to retract the actuator rod 36 and open the door or window or (2) a second rotational direction to extend the actuator rod 36 when closing the door or window.
In step 110, the same electrical parameter(s) used to generate the learned electronic signature is/are measured at the same discrete distance intervals of travel of the actuator rod 36 as the door or window 14 is either opened or closed during the non-trial.
In step 112, the measured electrical parameters at each of the discrete distance intervals of travel of the actuator rod 36 are compared to the same averaged measurement at the same discrete interval included in the learned electrical signature respectively.
In decision 114, it is determined if one or more comparison(s) exceeds a threshold.
In step 116, the controller 52 controls the actuator motor 32 to proceed with the opening or closing of the door or window 14 if the threshold is not exceeded.
In step 118, on the other hand, the controller 52 directs the actuator motor 32 to stop with the opening or closing of the door or window 14 if the threshold is exceeded one or multiple times. When the threshold is exceeded one or multiple times, the controller 52 makes an assumption that either (a) the door or window 14 is hitting an obstruction during the attempt to either open or close the door or window or (b) the door or window is closed and locked when the attempt to open the door or window is made.
Finally, in step 120, if Step 116 is successful, the learned electronic signature is updated with the measured electrical parameter(s) at each of the discrete distance intervals with the measurements collected in step 110.
The above-described steps 106 through 120 are preferably repeated with each command to either open or close the door or window 14. With each non-trial opening or closing, the learned electronic signature is updated. By updating using measurements collected during non-trial openings and closings of the door or window 14, the learned electrical signature is updated over time. As a result, the updated learned electrical signature compensates for a wide variety of changing conditions, such as wear and tear, a state of maintenance of the door or window 14, varying temperatures, humidity levels, season of the year, etc.
In various embodiments, the threshold may be set at different values. For instance, if one or more measured parameter(s) exceeds the corresponding measured parameter(s) in the in the learned electronic signature by ten percent or more, then the threshold is considered exceeded. The threshold percentage, however, may widely vary depending on a desired sensitivity. If a high degree of sensitivity is desired, then the threshold percentage is reduced, meaning just a small deviation between the measured parameter(s) and the learned electronic signature is sufficient to stop an opening or closing. On the other hand, if less sensitivity is desired, then the threshold percentage can be raised, meaning a larger deviation is required to stop the opening or closing.
Also, the number of times the threshold needs to be exceeded to stop the opening or closing may also vary based on sensitivity or accuracy. In general, more times the threshold is exceeded, the more accurate the assumption there is an obstruction. The few times the threshold is exceed before stopping an opening or closing, the more sensitive, or potentially, the less accurate. The number of times the threshold is exceeded, in addition to the magnitude, can also used to trigger when the opening or closing of a door or window is stopped.

In the initial step 132, the opening-closing system 12 is installed in a door or window. As previously noted, the installation may involve the retro-fitting into an already installed door or window in a building, such as a home, office or other structure. Alternatively, installation may mean integrating the installation at least partially inside the frame of the door or window 14 in the factory where the door or window is made. The door or window is then shipped to a building, again such as a home or office, were it is installed within the structure.
In step 134, an application or “app”, intended to remotely interact with and control the opening-closing system 12, is installed on one or more computing devices 78 belonging to one or more persons. In various embodiments, the one or more computing devices may include smart phones, tablet computers, laptop computers, desktop computers, etc. The application or app is typically software or code intended to be executed on any of the above-listed devices and can be distributed to the one or more persons in a variety of ways, such as by downloading from a web site, via a hard storage medium such as a CD-ROM or memory stick, or can be downloaded from an “app store”, such as Apple App Store or Google Play.
In step 136, each opening-closing system 12 is synchronized with each of the devices it is intended to interoperate with. Such devices may include, but is not limited to, the app running on one or more computing devices 78, one or more indoor camera(s) 72, one or more outdoor camera(s) 74, one or more personal assistant(s) 76, including RFID and/or Bluetooth tags (80). During the synchronization, certain credentials such as identifiers, IP addresses, and Wi-Fi credentials are exchanged so that all the synchronized devices can communicate with one another over the wireless network 71, such as the Internet, a local area network, a Wifi network, or a combination thereof. In step 138, preferences for the opening-closing system 12 are set. Such preferences may include the person or people who may control the remote opening and closing of the door or window in which the device is installed, the hours of operation, the pet(s) that may or may not have exit or entry privileges. As noted above for example, a dog may be granted exit/entry privileges, while a cat may not. Other preferences may include setting a limit on how much the door or window 14 is opened, depending on who is attempting to enter or exit. For example, with a large dog, the setting may limit the opening of the door to 20 inches wide, but only 10 inches wide for a smaller dog.
In other non-exclusive embodiments, the settings may also include if a pet can automatically trigger the open and/or closing of the door or window 14 or if human intervention is required.
Similarly, in the case of package deliveries, the opening of the door may be limited to only a few inches to allow the insertion of a small package or envelope, but small enough to prevent the delivery person access through the door and into the building or residence. Alternatively, settings can be established to control how wide a door or window 14 is opened based on package size. Using either visual recognition and/or artificial intelligence, the size of a package can be estimated. In response, the opening-closing system 12 opens the door or window 14 just enough to receive the package. In a variation of this embodiment, the delivery person can scan a bar code provided on the package. In response, information detailing the dimensions of the package is wirelessly delivered over network 71 to the opening-closing system 12, which in turn, opens the door or window 14 the appropriate amount to accommodate the delivery of the package.
Steps 142-146 detail operation of the opening-closing system 12 when preferences are set for pet activation. Typically, the pet will initiate some behavior that the opening-closing system 12 determines as an open or close request event (Step 142). Such an event may include the pet approaching the door or window and being sensed by one or more of the sensors 28, one or more of the of the cameras 72 and/or 74, the opening-closing system 12 is notified via an identification tag 80, or some combination of the above. In response to the sensed request event, the system 12 operates the actuator motor 32 to either open or close the door or window (step 144) by implementing the steps 106 through 120 of
Steps 150-158 detail operation of the opening-closing system 12 when preferences are set for human activation. With this scenario, an open or close event (step 150) is sensed by one or more of the sensors 28, indoor or outdoor camera(s) 72/74 and/or an ID tag 80. In response to the sensed event, the opening-closing system 12 notifies (step 152) one or more designated person(s) via a message such as an in-app notification, text message, voice or email message. In response the recipient is required to generate a command by way of app or voice controlled device instructing the opening or closing if the door or window 14 (step 156), which is typically delivered to the opening-closing system 12 via the wireless network 72. In response, the controller 52 opens or closes the door or window 14 (step 158) by implementing the steps 106 through 120 of
After the synchronization step 136 and the set preferences step 138, the remaining steps 140-146 and/or 148-158 may be repeated each time an open/close event is sensed.
It should be noted that the synchronization step 136 and the set preferences step 138 may need to be repeated from time to time to synchronize with new equipment (e.g., new cameras, identifier tags, personal assistants, new mobile devices, etc.) and/or when changes the set preferences is desired.
Referring to
In a first example, an arrival of a delivery person is sensed by an outdoor camera 74. In response, the opening-closing system 12 generates a message 182, such as a text message, which is sent to a mobile device 78 of one or more designated person(s) 184. In an optional embodiment, a barcode containing package information or visual recognition and artificial intelligence is used to determine the size of the package the delivery person is attempting to deliver. In response, one of the designated persons generates a remote command 186 to open the door or window 14 which is delivered via the wireless network 71 to the controller 52 of the opening-closing system 12. In turn, the system 12 activates the motor 32 to first open the door and then close the door after an adequate time period to deliver the package has lapsed. In embodiments where the size of the package is estimated, the controller 52 will open the door or window 14 just enough to readily accept the package, but preferably no wider. For example with an envelope, the door or window is opened just a few inches. But for a larger box or package, the door or window is opened a larger amount to accept the box or package.
In a second example also illustrated, a pet 190 triggers the generation of a message 192 by the opening-closing system 12 to the one or more designated persons in response to one of the video cameras 72, 74 and/or an ID tag 80. In reply, one of the designated persons may generate a command 186 to open or close the door or window 14 that is delivered via the wireless network 71.
In a variation of one or both of the examples above, media such as (1) video, (2) a still image and/or (3) a text message may be included in the messages 182, 192. In this way, the recipient will see and be informed of the sensed event that is triggering the request to either open or close the door or window 14.

Preferably, the exterior of the cover 204 is made of the same material (e.g., wood, vinyl or fiberglass) and is the same color as the frames 200, 202 of the sliding door 14. By matching the material and color, the cover 204 aesthetically looks like it is part of the door design and substantially conceals the opening-closing system 12. By making the cover 204 removable, access is provided to the opening-closing system 12 as needed for maintenance, repairs, etc. In alternative embodiments, the cover 204 can be fixed, meaning it is not removable.
Also shown in the diagram is a pin 206 that is used to engage or disengage the sliding frame 202 from the concealed window opening-closing system 12. When disengaged, the sliding frame 202 can be opened or closed only manually. When engaged, the sliding frame 202 can be remotely opened or closed in any of the ways already described herein.

Although the embodiment above is addresses to the opening-closing system 12 built into a sliding patio door, it should be understood that this is by no means a requirement. On the contrary, the opening-closing system 12 can be built into a wide variety of different types of doors and windows, including a swinging door, a sliding window, a casement window, a tilt-and-turn window, etc.
The swing-door opening closing system 300 is similar to the above-described system 12, meaning both include a house 26 for housing a sensor 28, an optional adjustable shutter 30, a screw 34 and actuator motor 32. The housing 26 further houses the controller system 50, including the controller 52, optionally the ball sensor 54, the sensor interface 56 for interfacing with the sensor 28 provided on the housing 26, the wireless network interface 58, an optional Internet of Things (IoT) interface module 60 and firmware 62. As each of these elements were previously described, an explanation of each is not provided herein for the sake of brevity.
The main difference between the previously described system 12 and the swing-door opening and closing system 300 is that the actuator rod 304 is curved.
With a curve, the actuator rod 304 “bends around a corner” and laterally moves between a closed and opened position. The actuator rod 304 also includes a base 304A that is arranged to be mechanically attached to the swing door 300. The attachment can be accomplished in any of a number of ways, including screws, bolts, double-stick tape, etc.
Referring to
Referring to
With this arrangement, the actuator motor 32 in the housing 26 can rotate the screw 34 in either a first rotational direction or a second rotational direction. In response, the curved actuator rod moves laterally, swinging the door 302 between an opened or closed position. As described in detail herein, the door 300 can be remotely opened or closed in a variety of ways, including triggering by a pet as sensed by a PIR sensor, video camera, or identifier tag, remotely by human intervention via a voice command from a personal digital assistant, from a remote app running on a smart phone, tablet or computer, etc., as described herein. In addition, the amount or degree to which a swing door or window is opened can also be controlled, for instance, based on pet size or the size of a delivered package or envelope. The smart swing-door opening and closing system 300 can thus be used to open or close a swing door or window in all the same ways as previously described above with regard to the smart opening closing system 12.
Certain swing doors may be used with a door lock that includes a latch bolt that is arranged to inserted into a door frame latch when locked and retracted with the door lock is opened. Referring to
Although the opening and closing system 300 has been described in the context of a swinging door, it should be understood that this is by no means a requirement. The system 300 can also be used with swinging windows as well.
It should further be noted that the opening and closing door or window systems 12, 300, as described herein, can be made to be extremely strong. By making the housing 26, screw 34, actuator rod 36/304 of mechanically strong materials, such as steel, fiberglass, strong plastics, etc., a high level of safety and security can be provided. With strong materials, a door or window can be made just as difficult, if not more difficult, to open and close as a door or window lock. As such, the smart door or window opening devices as described herein provides high degree of convenience, without having to sacrifice security. Environmental Sensors
In the above embodiments, the door or window opening-closing system 12 is used mostly in the context of allowing egress-ingress of a pet into a home or for the delivery of packages. It should be understood that the door or window opening-closing system 12 as described herein also has other applications.
As described in more detail below, the door or window opening-closing system 12 can also be used with environmental sensors, including but not limited to, a thermostat or thermometer that measures temperature, a humidity sensor, a smoke detector, or any other air quality sensors, such as a carbon monoxide sensor. For instance, the door or window opening-closing system 12 can be used to automatically (or possibly remotely) open or close a door or window when indoor air temperatures exceed or fall below a temperature threshold, exceed or fall below a humidity threshold, automatically open when smoke or other air contaminants such as carbon monoxide is detected inside a building or structure, and automatically close if the smoke or other contaminants inside the building or structure dissipate.

In step 402, a sensor senses an environmental condition. In various embodiments, the environmental condition may be, as noted above, temperature, humidity, smoke, carbon monoxide, or other air contaminants and the sensor may be a thermometer, thermostat, humidity detector, smoke detector, carbon monoxide detector, or any other type of air sensor designed to detect various types of contaminants in the air. In yet other embodiments, the sensor or sensors may be located inside or outside the building or structure in which a door or window controlled by the opening-closing system 12 is installed. Regardless of the type or location of the sensor(s), the sensed information is preferably wirelessly transmitted to the controller 52 of the opening-closing system 12 using a local wireless network such as RFID, WiFi, the Internet, a short-range wireless communication protocol such as Bluetooth®, or any combination thereof.
In step 404, the controller 52 continually, or at periodic intervals, receives the sensed information and compares it to a first threshold. For example, if the sensed information is an indoor air temperature or a carbon monoxide level, the sensed information is compared to a first threshold temperature or first carbon monoxide level respectively. It should be understood that the sensed information and the first threshold need not be limited to a single parameter such as temperature or humidity. On the contrary, the sensed information can be a combination of sensed parameters, such as a combination of both temperature and humidity and the threshold can be adjusted based on a predetermined combination of the two. For example, as humidity increases, then the temperature requirement to trigger the opening of the door or window may be lowered. Alternatively, if the humidity is low, then the temperature for triggering the opening of the door or window may be higher. It therefore should be understood that the term “first threshold” as used herein should be broadly construed to mean one of (i) a condition based on one sensed parameter that is static, (ii) a condition based on a combination of two or more sensed parameters that are non-variable or static, or (iii) possibly a condition of one or more sensed parameters that are variable, meaning as one (or more) parameters change, the threshold that triggers the opening of the door or window may also change. Although a combination of temperature and humidity to control the opening and closing of a door or window is described, it should be understood that by no means should this example be construed as limiting. On the contrary, the present application contemplates the opening and closing control of a door or window based on one or a combination of multiple sensors and the trigger threshold can be either static or may vary depending in how the information sensed by multiple sensors affect or influence conditions that warrant an opening or closing event.
If the comparison indicates that the first threshold is exceeded, then the controller 52 operates the opening-closing system 12 to automatically open the controlled window or door. For instance if the indoor temperature becomes too hot, and exceeds a temperature threshold (e.g., 80° F.) or inside carbon monoxide levels become too high and exceed a threshold, then the window or door is automatically opened (Step 406), allowing cooler or non-contaminated air into the interior of the building or structure. On the other hand if the first threshold is not exceeded, then the window or door remains closed. Again, the term “second threshold as used herein, should be broadly construed to mean one of (i) a condition based on one sensed parameter that is static, (ii) a condition based on a combination of two or more sensed parameters that are non-variable or static, or (iii) possibly a condition of one or more sensed parameters that are variable, meaning as one (or more) parameters change, the threshold that triggers the opening of the door or window may also change.
In step 408, the controller 52 also operates continuously, or at periodic intervals, to compare the received sensor information to a second threshold. Again, for example, if the sensed information falls below the second threshold, or if any predetermined combination and/or collection of sensors, is compared together in the context of threshold such as temperature and humidity, then in step 410, the controller operates the opening-closing system 12 to automatically close the window or door. So for instance of the indoor air temperature drops below the second threshold because the door or window is opened, then the opening-closing system 12 will automatically close the door or window.
In non-exclusive embodiments, the steps 402 through 410 are continuously performed. In this way, the door or window, controlled by the opening-closing system 12, is either automatically opened or closed as the sensed environmental condition changes.
The automatic opening and closing of a window or door, based on changing environmental conditions, offers a number of real-world benefits. Such beneficial applications may include:
In the above-described embodiments, the door or window controlled by the opening-closing system 12 was automatically either open or closed based on how the sensed information compares to the first and second thresholds of one or more sensors. Alternatively, when the sensed information either exceeds or falls below either of the first or second thresholds, the controller 52 may generate a notice to the remote communication device of a designated user. In this embodiment, the door or window controlled by the opening-closing system 12 may then either open or close the door or window in response to a command received from the remote communication device generated by the user in reply to the notice.
In the above-described embodiments involving package delivery, a door or window was opened based on the sensing and/or visual recognition of a delivery person carrying a package in the vicinity of a door or window controlled by the opening-closing system 12. In an improvement embodiment, the opening-closing system 12 can also be used with digital keys that enable the opening of a door, window or delivery box when a package is about to be delivered.
Referring to
In step 502, a digital key is assigned to the opening-closing system 12. The digital key can be a unique digital code or other electronic signature that is unique to the opening-closing system 12. In various embodiments, the digital key may be assigned by any of a number of different parties, including but not limited to the manufacturer of the opening-closing system 12, the maker of the door, window, and/or delivery box in which the opening-closing system 12 is installed, a home owner or building occupant, a delivery service company, etc. Regardless of the type or assignee, the digital key is used to control the opening-closing system 12. In other words when the opening-closing system 12 receives its unique digital key, the door, window or delivery box in which the system 12 is installed will open, allowing an acceptance of a package. Once the package is delivered, the opening-closing system 12 will close the door, window or delivery box.
In step 504, the digital key is shared with a package delivery company. This may be accomplished in a number of different ways. For instance, a home owner or occupant may open an online account with a delivery service company (e.g., Fedex, UPS, DHL, US Postal, etc.) and share their credentials, including the digital key. Alternatively, the delivery service company may assign the digital key to a customer and their opening-closing system 12. In yet another embodiment, the entity that makes the opening-closing system 12 may share the digital key with the one or more of delivery service companies.
In step 506, the package delivery service associates the digital key with other pertinent information. Such other pertinent information may include an identifier associated with the opening-closing system 12 used by a package recipient, the credentials of the package recipient such as a name, address, etc. By associating the digital key with such information, the unique digital key for the opening-closing system 12 used by a recipient of packages for that person or address can be readily obtained and used when needed, as described below.
Most online retailers and delivery service companies rely on QR and/or bar codes for the processing and delivery of packages. For instance, when an item is purchased online, the online retailer, in cooperation with their chosen package delivery service company, generates a tracking number for the package. The tracking number is then typically emailed to the purchaser so they can track the progress of the delivery of the package. In addition, a shipping label is created with (i) a human readable tracking number and (ii) a machine readable QR and/or bar code that is associated with the tracking number, as well as other pertinent information, such as the recipient name, address, sender, etc.
When a package is delivered, the QR and/or bar code is typically scanned by a hand-held device used by the delivery person. The scanning of the QR and/or bar code signifies that the package has been delivered and typically results in some type of electronic notice (e.g., a text message or email) informing the parties involved that the package has been delivered.
In this package delivery embodiment, the scanning of a package is used as a trigger event to broadcast the digital key used to activate the opening-closing system 12. In other words when the delivery person scans the QR and/or bar code on the package (decision step 508), the hand-held device retrieves the correct digital key based on the previous association with the information contained in the delivery system app, such as the recipient, name, address, etc. In a variation of this embodiment, the broadcast of the digital key used to activate the opening-closing system may be based on location as determined by GPS or some other location service. In other words as a delivery vehicle arrives at an address for the delivery of a package, the hand-held device may retrieve the digital key before the delivery person scans the QR and/or bar code.
The hand-held device then broadcast (step 510) the digital key associated with a package. This broadcast cast as shown in figure could be based on the scanning of the QR and/or barcode, or by identifying when the driver is in proximity of the address for the delivery and open the door, window, or box prior to scanning the barcode. Either way, the door, window or box is preferably opened prior to the delivery person physically delivering the package. In this way, the package can be quickly delivered without waiting for the door, window or box to open. Given that most delivery persons have a tight schedule, and have to make numerous deliveries during a given day, the accumulated time savings of not having to wait for doors, windows and/or boxes to open at multiple delivery locations can be a significant advantage.
In response, the opening-closing system 12 is activated (step 512) and the door, window or delivery box is opened, allowing for the insertion of the package.
In optional step 514, the door, window or delivery box can be opened a degree just large enough to allow the package to pass through. As described above, the opening-closing system 12 can control the degree of the opening based on visual recognition and/or information received via the broadcast, such as the barcode information in addition to the digital key.
