(22) Turning now to the figures, FIGS. 1-3, 4A and 4B illustrate an exemplary module 10. The term “module” refers to an assembly that includes hardware and software components. As shown, the module 10 includes a housing 12 and a front cover 15 (e.g., door). The housing 12 has an internal open cavity 12c (FIG. 3) for holding a container 20 (FIGS. 3-5). The front cover 15 includes at least one port 16 for transmitting fluid from the container 20 in the housing 12 out of the at least one port 16.

(23) The module 10 is particularly suitable as a room freshener module that holds a room freshener container 20. The remainder of the application will refer to the module 10 for this use. However, the module 10 may also be used to dispense other types of substances such as, for example, insect repellant, including mosquito repellant, which may be appropriate for areas where doors are sometimes open (e.g., garages) or for open or screened in patios or decks, or locker rooms, for example.

(24) The module 10 may include a voice command input as the input 41 or as a separate input, which may be particularly suitable for insect repellant use. The voice command inputs can include “spray now” or “OFF” so that no spray is initiated until animals or people are out of proximity. The module 10 may have a proximity detector 29 (FIG. 5) that detects for the presence of animals or people prior to initiating the dispensing. The proximity detector can include a camera, motion-detection sensor and the like.

(25) The front cover 15 can be hingeably attached to one long side of the housing 12, as shown. The front cover 15 can be attached in other ways. For example, the front cover 15 can be attached via a hinge at the top or bottom of the housing 12 or the front cover 15 can be slidably attached to allow it to move up or down relative to the housing 12 to allow access to the cavity 12c (not shown).

(26) As shown in FIG. 2, the port 16 can be surrounded by a wall 16w that is recessed relative to the primary body of the door 15b that surrounds the port. The wall 16w can taper to be larger as it travels outward, away from the cavity of the housing 12c.

(27) The cover 15 can be configured to automatically close. A controller 127 (FIG. 4B, 5) in the housing 12, typically on the PCB 26, can direct the cover 15 to close upon release of any force holding the cover 15 open using a sensor for feedback on any user force holding the door open. In some embodiments, the cover 15 can be mechanically configured (e.g., spring biased) to automatically close without requiring electrical control or to release a lock that causes the mechanical structure to close the door 15.

(28) The front cover 15 can provide a User Interface (UI) 40 including at least one input device 41 that can be configured to allow a user to manually operate the module 10 for on-demand operation of the module 10. The at least one input device 41 can also or alternatively allow a user to adjust a frequency of dispensing of the room freshener substance and/or adjust a sound level of an audible alert 42. The alert 42 can emit audible sound during and/or just prior to an active dispensing of the room freshener. The sound can be a siren or audible frequency sound and/or a verbal alert such as “stand back” dispensing in “3-2-1”, for example. The UI input device 41 can be configured as a push-button, slider or rotary switch or other manual input.

(29) The front cover 15 may include an indicator light 43, such as an LED light, which can provide color status outputs such as, for example, “green” for normal status, “yellow” or “blinking green” for low content in the container 20 status, and/or “red” for malfunction and the like. The indicator light 43 can be used to visually alert of an impending active dispensing of the room freshener.

(30) The front cover 15 may also or alternatively include a display screen 45 (FIG. 1), such as a touch screen display or a display with a keyboard UI, for allowing a user to reset or set desired features or adjust defined features such as numbers of dispensing actions (two sprays, one spray, etc., per respective dispensing), frequency and the like.

(31) The room freshener module 10 can include an electronic odor detector/sensor that can automatically trigger the module 10 to dispense room freshener. See, e.g., Persaud, Krishna; Dodd, George (1982). “Analysis of discrimination mechanisms in the mammalian olfactory system using a model nose”. Nature 299 (5881): 352-5. Jin, Hye Jun; Lee, Sang Hun; Kim, Tae Hyun; Park, Juhun; Song, Hyun Seok; Park, Tai Hyun; Hong, Seunghun (2012). “Nanovesicle-based bioelectronic nose platform mimicking human olfactory signal transduction”. Biosensors and Bioelectronics 35 (1): 335-41. The contents of these documents are hereby incorporated by reference as if recited in full herein.

(32) In some embodiments, the housing 12 can also hold at least one actuator 50 (FIGS. 4A, 4B) that is in cooperating alignment with the room freshener container 20 to cause the room freshener container 20 to dispense room freshener through the port 16 in the cover 15.

(33) The container 20 can hold fluid, e.g., liquid or gas and/or powder as the room freshener substance. In some particular embodiments, the container 20 is a spray canister with a nozzle 21 with a spray port 21p. The nozzle 21 can be depressed by the actuator 50 to spray fluid or powder. In other embodiments, the container 20 may be an infusion dispensing device or have a different operational configuration that does not require active spraying and/or depression of a nozzle.

(34) While FIGS. 4A and 4B illustrate the container 20 in an upright orientation with the nozzle 21 above the container body, the container 20 can be used in other orientations, e.g., the reverse orientation. In still other embodiments, the nozzle 21 can be oriented to extend out of the port 16 in the cover 15 to dispense room freshener down or up relative to the cover 15, instead of straight out of the cover 15 as shown.

(35) FIG. 4A illustrates that the housing 12 can include a printed circuit board cover 19 that can reside above the container nozzle 21 and can attach to the printed circuit board to enclose the components held above the bottom of the PCB 26. This may be a fluid-tight attachment or fluid-resistant attachment to help isolate the electrical components from undue exposure to moisture.

(36) It is also noted that the container 20 is shown in a rigid or semi-rigid self-supporting body but flexible package containers may also be used in the module 10. If so, suitable suspension support members can be used to hold the flex-package container in position for dispensing the substance (not shown). A spring-loaded member can be used to compress the flex-package as its content is depleted (not shown).

(37) In some embodiments, the container 20 can hold a fluid (liquid and/or pressurized gas) room freshener substance. In some embodiments, the container 20 can hold liquid room freshener. The container 20 can hold a conventional volume, such as a volume at normal use, (that is, between a 10 day-90 day supply), but other volumes are contemplated. In some embodiments, the containers 20 have a capacity of between 1 ounce and 32 ounces, typically between 2 and 16 ounces, and more typically between about 4 ounces and 12 ounces.

(38) The container 20 can hold a substance for dispensing through the port 16 that may be odorless or have a fragrance.

(39) The actuator 50 can be a single actuator or a plurality of actuators. The actuator 50 can be a linear and/or rotary actuator. The actuator 50 can comprise, without limitation, a solenoid, a stepper motor, a custom motor, a piezoelectric translator (transducer), a pneumatic cylinder and the like. The actuator 50 can be at any suitable location in the housing including on a sidewall, bottom, ceiling or rear wall of the housing or even on a back of the cover 15. The actuator 50 can be held a support at other locations in the housing 12.

(40) The housing 12 can hold a printed circuit board (PCB) assembly 25 with a printed circuit board 26 and defined operational components 27 (FIG. 4B). The term “printed circuit board” is used broadly and can include flex circuits or other substrates in a single or multiple layers or components that provide defined electrical paths. Thus, the printed circuit board 26 can comprise a flex circuit with a flexible substrate body and is not required to have a rigid or semi-rigid substrate body. The components 27 can include sensors, a power supply and drive circuitry and a controller 127.

(41) In some embodiments, the components 27 include a sensor 27s that can detect whether the cover 15 is open and suspend any active dispensing if the cover is open. A sensor 27s can be used to confirm that a container 20 is in a proper position in the housing 12. If empty or out of position, the indicator light 43 can generate the “malfunction” or “low content” visual signal. A sensor 27s can detect a presence of a container 20 before actuating the actuator 50 and/or for generating an alert to a user, for example. For the “low content” or “empty” monitoring, the sensor may detect weight or numbers of dispensing actions to “decrement” a predicted pre-defined or pre-set number of actions for a “full” container, or other appropriate parameter.

(42) FIG. 5 is a schematic illustration of a control circuit 10c that can be totally or partially onboard the room freshener module 10. The control circuit 10c can include the controller 127 which can allow for adjustable settings 127such as dispense times, frequencies and the like. The controller 127 can communicate with the actuator 50 and/or the alarms 42, 43 (visual indicator and/or audible alert). The control circuit 10c can include various sensor inputs 27ssuch as a door open sensor 27s, low volume sensor 27s, container position sensor 27s. The controller 127 may communicate with a whole house control circuit 200 and/or a user device 225.

(43) The module 10 can be hard wired to an electrical power circuit 300 (FIG. 9) of a building or complex, such as a recreational facility, school, hospital, nursing home, residence, hotel, motel or office building, with wires 30 as shown. The power circuit 300 can be a multi-purpose power circuit such as a conventional power circuit powering other uses such as electrical outlets, lights and the like, in a home or office.

(44) As shown in FIG. 2, the housing 12 can include wire ports 12p in a wall thereof, e.g., typically the sidewall, but the rear wall, ceiling or floor may hold one or more of the wire ports 12p. The wires 30 can extend through the ports 12p and can include wires 30 similar to a receptacle or switch from the electrical power circuit 300 (FIG. 9), including HOT, NEUTRAL and GROUND connections and wiring. The wires 30 can be connected to the PCB assembly 25 to power the power supply and/or other components 27.

(45) As shown in FIG. 4B, the printed circuit board (PCB) 26 can have be sized and configured to be orthogonal to the cover 15 and fit in the housing in a depth dimension as shown. However, in other embodiments, the PCB 26 can be parallel to the front cover 15 and/or reside against a side or rear wall of the housing 12. More than one printed circuit board 26 may be used for a respective room freshener module.

(46) The module 10 can have a transceiver or transmitter-receiver for communicating over a wireless network, such as an intranet or the Internet. The module 10 can have an assigned ISP address.

(47) Referring to FIGS. 3, 4A and 4B, the housing 12 of the room freshener module 10 can include a support member 35 such as a plate/platform 36 that can support the container 20. The housing 13 can also include an x, y, z adjustable mounting system 35 such as pairs of cooperating rails 37 that slidably receive the platform 36 to allow the platform 36 to be positioned at different vertical levels. The mounting system 35 can have lateral adjustability and depth dimension adjustability to move the container 20 in three dimensions for x, y and/or z adjustment. The platform 36 may include upwardly extending sides F to hold the container side to side and/or back to back for proper alignment with the actuator 50. The module 10 can be configured to serially cooperate with different size and/or shaped containers 20, including containers from different manufacturers and/or containers of various sizes with different volumes of room freshener.

(48) The housing 12 of a module 10 can be configured to hold a plurality of containers 20, each in communication with a single port 16 or the cover 15 can have a plurality of ports 16, one for each container in the housing 12.

(49) While the actuator 50 is shown residing above the container 20 in FIGS. 4 and 5, where used, an actuator 50 can be located in different locations, including under or behind the container 20.

(50) FIG. 4B also schematically illustrates that the module 10 may include a vibration device 60 or “agitator” for shaking the container 20 to help mix the room freshener substance. The vibration device 60 can be configured to move the container side-to-side and/or up-and-down to shake the container 20. The vibration device 60 can also include an actuator such as one or more of those described above.

(51) In some embodiments a common actuator 50/60 can be used to vibrate or agitate the container, then dispense the room freshener substance from the container 20.

(52) The housing 12 may hold a heater such as a heating element and/or heated jacket for the container 20 to warm the container 20 to a defined temperature (not shown) for dispensing or prior to dispensing the room freshener substance from the container 20.

(53) As shown in FIGS. 6A and 6B, in some embodiments, the housing 12 can be configured to be held in a single gang mounting or junction box 112 for ease of installation to a wall (typically nailed or screwed to a vertical or horizontal stud via apertures 113). The wall can be an interior wall or an exterior wall and may, in some embodiments, be a wall of a room.

(54) Thus, the housing 12 can have a depth dimension “D” that is between about 1.25 inches and about 1.75 inches, such as about 1.5 inches, or slightly smaller than a gang box depth and/or width/height. Standard single gang box depth dimensions come in 1.59 inch and 1.89 inch depths. The height and width dimensions “H” and “W”, respectively can be between about 3-4 inches (H) and between about 2-2.5 inches (width), in some embodiments. The front cover 15 may attach to the gang box tabs 114 and/or to the housing 12.

(55) As shown in FIG. 7, the housing 12 can be configured to be held in a multi-gang junction or mounting box 112 such as a double or triple gang junction box. In the embodiment shown, a light switch unit 95 (or electrical outlet unit) is held in another compartment of the multiple gang box 112.

(56) As also shown in FIG. 7, the cover 15 can be substantially flush with the outer surface of the wall 100 in or through which the housing 12 resides and can visually have the same shape and/or surface mount appearance as a light switch wall plate 95c. The term “substantially flush” means the cover 15 resides in a plane that is parallel to and between 0.01 inches to about 0.25 inches offset from a plane of the outer surface of the wall to which the housing is mounted and/or resides within, typically similar to conventional lighting switch covers (95, FIG. 7).

(57) In some embodiments, the housing 12 may alternatively have a custom size and is not required to be modular or standardized to fit standard gang mounting or junction boxes.

(58) FIG. 8A illustrates that the module 10 can include a flow path adapter 160 that provides an enclosed path between the container 20 and the port 16 through the door 15. The adapter 160 can be flexible or resilient to be able to compress axially when the door 15 is closed. The adapter 160 can be attached to the door 15 and may be a replaceable component. The adapter 160 may be configured with a collar 161 that can attach to the neck 23 of the container 20 as shown in FIG. 8B, for example.

(59) FIG. 8C illustrates that the adapter 160 can extend out a distance beyond the front surface of the door 15. The adapter 160 can be elastomeric and flexible to allow a user to compress the adapter to remove or install it to the door 15. The adapter 160 may seal against the door 15, in some embodiments.

(60) As shown in FIG. 9, the housing 12 can be held on a wall 100 of a room with a light switch adjacent a light switch unit 95 and/or electrical outlets, including Arc Fault Circuit

(61) Interrupter (AFCI) or Ground Fault Circuit Interrupter (GFCI) units. FIG. 9 also illustrates that the room freshener 10 can be mounted as a discrete unit and may be placed in any desired location, shown as below normal light switch positions.

(62) FIGS. 10 and 11 illustrate a control circuit 200 which can be a “whole house” control circuit. FIG. 10 illustrates that the control circuit 200 can have at least one primary controller 202 that directs different modules such as a lighting module 95, security module 115, and heat/A/C module 105, for adjusting/setting various operational conditions, including, for example, “ON”, “OFF”, and “TIME”, and for the heat/A/C module “TEMPERATURE” at days, times, etc . . . The control circuit 200 can be a wireless circuit and/or may be hard-wired to one or more modules 10, 95, 105, 115. The wireless connectivity, where used, can be via BLUETOOTH®, ZIGBEE®, or Z-WAVE and the like or any wireless protocols in existence now or in the future.

(63) The circuit 200 can also be configured to operate with a user device 225 having a User Interface (UI) 226. As shown, the user device 225 can wirelessly communicate with the controller 202 and/or with specific modules, including the room freshener module 10. The UI 226 can be a Graphic User Interface (GUI) or keypad UI or other UI that allows a user to adjust or select various operational features of the module 10. The user device 225 can be a computer, smartphone, electronic notebook, and the like. The UI 226 can be provided via an APP. The term “APP” refers to a program or piece of software designed to fulfill a particular purpose; an application, especially as downloaded by a user to a mobile device.

(64) As shown in FIG. 11, the dispensing module 10 can be associated with a defined “spray” or “dispense” icon such as a canister and nose shown at the top of the circle of different control inputs. A similar icon/graphic can be provided as an APP for controlling the module 10.
