Description




BACKGROUND




1. Field of the Invention




The present invention relates generally to baby monitors, and more particularly, to two-way communication baby monitors with a soothing unit.




2. Discussion of the Related Art




Two-way communication baby monitors are known. Additionally, crib entertainment devices are also known. Parents frequently wish to monitor their child's activity while not within an audible range of the child. Baby monitors have been used to provide such a function. Baby monitors have been developed that allow two-way communication so that a parent may talk to the infant being monitored to reassure or soothe the infant. Entertainment devices, such as mobiles, have also been configured to provide a one-way monitoring function as well as to provide remotely operated entertainment features.




These two-way monitoring devices and entertainment devices typically exist as separate units in a child's room. For example, the baby unit of the monitor is typically located in the child's room in some area near the crib, while the entertainment device is typically a separate unit that is attached to the crib.




Because these units are separate, parents are required to maintain the operation of each unit and to keep track of the various monitors and controllers that are associated with each product. Moreover, infant's rooms often have limited space and multiple devices create unwanted clutter. Whereas there have been attempts to overcome this problem by placing monitors and entertainment devices in cribs or suspended above cribs, there is a need for a baby monitor capable of providing two-way communication as well as having soothing features that are part of a single baby unit.




SUMMARY OF THE INVENTION




A baby monitor system with a parent unit communicable with a baby unit having a soothing unit is provided. In an embodiment for the baby monitor system of the present invention, the baby unit is responsive to receiving a signal representative of an audible sound transmitted from the parent unit and the parent unit is responsive to receiving a signal representative of an audible sound transmitted from the baby unit.




In an embodiment for a method of the present invention, a method for monitoring a baby is provided. The method includes the steps of receiving a signal representative of an audible sound at a baby unit from a parent unit, receiving a signal representative of an audible sound at a parent unit from a baby unit, and actuating a soothing unit included in the baby unit.

R or local user input module


20


L, the controller


130


controls the output of selected baby unit output


40


(i.e., the operator selected soothing features), such as musical notes, sound effects, light patterns or combinations of musical notes and light patterns, from the output module


40


. Likewise, the controller


130


controls the output of communication received from the parent unit


200


(e.g., the parent's voice transmitted to the baby unit


300


).




Baby unit output module


40


(implemented as soothing unit


400


which is further described below) includes output content


42


, which includes audio content


42


A and video content


42


B. Audio content

42


by the user, and the performance attributes of the output generators, should be informed by the goal of generating output that is appealing or soothing to an infant. Audio volume levels should be selected to soothe, rather than startle, the infant. Audio content should be soothing, pleasing, comforting, and/or rhythmic or melodic. Video output intensities should be high enough such that the video output is visible to the baby in a darkened room, but low enough such that the baby is not kept awake. Video output should also be pleasing and include familiar static or animated patterns or images, or rhythmically repeated abstract patterns or images.




Controller


130


includes control module


31


which controls output module


40


, responsive to user input modules

receives the mode selection and the start command, accesses the output content


42


corresponding to the mode selection, and activates the output generator


44


to output the selected output content. Use of the remote actuator


26




a


to issue the start command allows the user to be positioned remote from the infant, so that the soothing output can be initiated while minimizing the risk that the user will disturb, or attract the attention of, the infant.




A first physical implementation of an embodiment of the present invention is now described with reference to

FIGS. 3

to


14


. As described previously, baby monitor system


100


includes a parent unit


200


and a baby unit


300


. The correspondence between the functional elements and the parent and baby units is illustrated in

FIG. 2

by phantom-lined boxes, identified as parent unit


200


and baby unit


300


, drawn around the functional elements. Electrical schematic illustrations of the baby unit


300


are shown in

FIGS. 10 and 11

and an electrical schematic illustration of the parent unit


200


is shown in FIG.


14


.




As shown in

FIGS. 3-9

, the components of the baby unit


300


are contained and supported in a housing


305


. Baby unit housing


305


is composed of front and rear housing portions


307


,


309


. Baby unit housing


305


has a top portion


303


and includes a substantially planar base


304


, upon which the baby unit


300


may be positioned on a support structure, such as a dresser, changing table, or nightstand, in operative proximity to an infant sleeping area. The rear portion


309


of baby unit housing


305


further includes a cavity


420


for receiving the soothing unit


400


and stopping surfaces


322


,


324


for defining the range of motion of the soothing unit


400


as will be described in detail below.




In the illustrated embodiment, the soothing unit


400


may include a light unit or nightlight


318


that is located on the front portion


307


of the housing


305


and includes Light Emitting Diodes (LEDs) to provide an appropriate level of illumination. A translucent screen


319


is provided in front of the LEDs to provide color and pattern to the light. The screen includes images that are pleasing to a child such as stars and moons.




The video output generator


46


is also incorporated as part of the soothing unit


400


and includes a projector


405


that directs an image that is pleasing to a child onto a surface spaced apart from the baby unit


300


such as a ceiling or wall. The projector


405


is pivotally coupled to the housing


305


within cavity


420


and is able to rotate so that the projected image can be directed to multiple positions without having to move the baby unit


300


. In this manner, the baby unit


300


can be situated on a support surface adjacent a crib or bed while the image is projected directly above the crib to provide a soothing and entertaining effect for the child positioned in the crib. The arc of rotation of the projector


405


is defined by stopping surfaces


322


,


324


and the projector


405


is able to lock into multiple positions along the arc of rotation. The projector


405


may lock in-place through the use of a detent mechanism, as is known by those skilled in the art.




Referring to

FIGS. 4-9

, further description of the operation of the projector


405


will now be provided. The projector


405


projects an image on a surface spaced from the projector by shining a light through a film


500


and projecting an image on the film through a lens


425


to project the image onto an opposing surface. A light bulb


402


is housed within a cavity


430


inside projector


405


. Contacts


452


are provided within cavity


430


for supplying current to the bulb. The bulb may be coupled to the inner surface of cover


412


of projector


405


such that when the cover is removed from the projector


405


, the light bulb is easily removed. The light bulb is positioned to shine through an opening


465


within the projector


405


such that it passes through the film


500


. The film


500


is coupled to a film guide disk


460


that rotates such that the film


500


passes by the opening


465


to give the appearance that the projected image is moving.




The film guide disk


460


is a substantially circular disk with a flat outer surface that is capable of retaining an edge of the film


500


. As illustrated in

FIG. 9

, the film


500


extends out past an outer edge


461


of the disk


460


such that an image on the film is unobstructed by the disk


460


as it passes over the opening


465


. In this manner, the light may shine through the opening


465


and through the film


500


, unobstructed by the guide disk


460


, to project the image on the film


500


onto a surface in the baby's room. The guide disk


460


is rotated by a series of gears


620


,


630


that are driven by a motor (not visible) contained within motor housing


600


.




The baby unit


300


may be turned on and off via power switch


312


. A power indicator


316


is provided on front housing portion


307


to indicate whether or not power is being supplied to the unit. Various modes of operation of the baby unit


300


are alternatively selected by mode selector


322


and mode selector


382


. Via mode switch


322


, implemented as switch SW


3


A as can be seen in

FIG. 11

, the user may select which video output (i.e., nightlight or projector) is provided at the baby unit


300


. Via mode switch


382


, implemented as switch SW


1


A, which can also be seen in

FIG. 11

, the user selects a combination of sound effects, music and/or lights, as selected, (e.g., night light or projector) that will be played during operation of the unit. In a mode of operation, when the switch SW


1


A is in a first position at location P


1


in switch cavity


317


in front housing portion


307


, controller


130


causes no music or sound effects, but the projector or nightlight will operate. When switch SW


1


A is in a second position at location P


2


, the controller


130


will cause the projector or the nightlight to operate and music will be played. A number of musical selections may be incorporated in the device. When the switch SW


1


A is in a third position at location P


3


, sound effects, such as waves or crickets, will be played and the projector or the nightlight will operate.




The baby unit


300


also includes an actuator


320


that may be used to activate the soothing unit


400


. Actuator


320


is implemented as a button in the front housing


307


of the baby unit


300


, which, when depressed by the user, closes a switch SW


3


(see

FIG. 11

) and sends a corresponding input signal to the controller


130


. Each actuation of the local soothing actuator


320


causes the soothing unit


400


to turn on or off. When the mode switch SW


1


A is at location P


2


, each successive actuation of the soothing actuator will cause a different melody to be played. As discussed above, a variety of melodies may be stored in controller


130


. The baby unit


300


is further provided with a channel selector switch


314


(implemented as switch SW


1


B in

FIG. 10

) to choose a two-way communication channel between the baby unit


300


and the parent unit


200


. The availability of multiple communication channels allows the user to select a channel that is not subject to interference by other electronic devices in the home.




The soothing unit


400


also includes a speaker


380


mounted in the baby unit housing


305


behind a perforated speaker grill


381


. The speaker is a 2.25 inch (5.715 cm) diameter driver, and is preferably driven to a sound pressure level of less than approximately 90 dB at 12 inches from the front of the speaker source. The speaker


380


is used to transmit audio output such as music and sound effects from the soothing unit as well as voice signals received from the parent unit


200


. Optionally, different speakers may be used for each type of output.




An embodiment of the parent unit


200


will now be described with reference to

FIGS. 3

, and


12


-


14


. The parent unit


200


is compact in size to make it readily portable and less cumbersome. The parent unit may be provided with a clip


260


to attach to, for example, the belt of the user such that the parent unit


200


may be easily transported. The components of the parent unit


200


are contained and supported in a housing


205


. The front portion


207


of the housing


205


includes a window


219


through which illuminated light emitting diodes may be viewed. The parent unit may be provided with either A/C or D/C power.




The parent unit


200


may be turned on, and the volume may be adjusted, via power switch


212


(implemented as switch SW


2


in FIG.


14


). The audio output generator


55


of the parent unit includes a speaker


280


mounted within the parent unit


200


behind a speaker grill


281


. The speaker is a 1.5 inch (3.81 cm) diameter driver, and is preferably driven to a sound pressure level of less than approximately 100 dB at 12 inches from the front of the speaker source. The parent unit


200


further includes a channel selector switch


214


to choose a communication channel between the baby unit


300


and the parent unit


200


.




The parent unit


200


also includes remote user input module


20


R, as described previously, via which the user can provide input to the baby unit


300


for effecting operation of the baby unit


300


. The remote user input module


20


R is implemented as remote soothing actuator


220


(implemented as switch SW


3


in

FIG. 14

) and a talk actuator


230


(implemented as switch SW


5


in FIG.


14


). When the soothing actuator


220


is depressed, switch SW


3


closes and sends a corresponding signal to the controller


130


via antenna


250


. The remote soothing actuator


220


functions in a manner similar to the local soothing actuator


320


on the baby unit


300


, providing only start and stop signals to controller


130


, as described above, for turning the soothing unit


400


on and off.




When the talk actuator


230


(switch SW


5


) is depressed, the user may speak into a microphone (not visible) and a signal representative of the user's spoken words is transmitted to the baby unit


300


and ultimately output at speaker


380


, as was also described above. When switch SW


3


is not depressed, the microphone is muted and sounds will not be transmitted from the parent unit


200


.




An alternative embodiment of the parent unit is illustrated in

FIGS. 15 and 16

. The parent unit


200


′ includes a housing


205


′ and a flexible antenna


250


′. The flexible antenna has a proximal end


252


coupled to the housing and a distal end


254


with a body


256


extending therebetween. A retainer


255


is coupled to the housing


205


′ and is able to maintain the antenna in an alternative position adjacent the housing


205


′ of the parent unit


200


′. The antenna


250


′ is reconfigurable between a first configuration where the body


256


is disposed away from the housing


205


′ and a second configuration (illustrated in

FIG. 16

) where the body


256


of the antenna


250


′ is disposed adjacent to the housing


205


′ within the retainer


255


. As illustrated in

FIG. 16

, the antenna in the second position takes on a substantially arcuate configuration with the distal end


254


contacting the supporting surface on which the parent unit is situated. Alternatively, the antenna


250


′ may be shorter in length where, while still maintaining an arcuate configuration, the distal end


254


does not contact the supporting surface upon which the parent unit


200


′ is situated.




The retainer


255


, which maintains the position of the antenna in its folded configuration, may be a detent in the body of the housing


205


′, as illustrated in FIG.


16


. Optionally, the retainer


255


may be a clip (not shown) attached to the outside of housing


205


′.




The reconfigurable antenna


250


′ of the alternative embodiment of the parent unit


200


′ desirably provides for reducing the volume required for the physical space where the parent unit


200


′ is positioned.




The reconfigurable antenna


250


′ may be manufactured from a variety of materials including, but not limited to, malleable plastic or rubber. Alternatively, the reconfigurable antenna


250


′ may be manufactured to include an internal flexible, reconfigurable member, constructed from either plastic or metal, which is surrounded by a flexible material.




In another embodiment of the invention, the microphone of the parent unit


200


and/or the baby unit


300


may be positioned on a distal end of the antennae


250
