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.
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.
The various features of the invention will best be appreciated by simultaneous reference to the description which follows and the accompanying drawings, in which:
As such, the baby unit 300 is two-way communicable with the parent unit 200. The baby unit 300 is responsive to receiving a signal representative of an audible sound transmitted from the parent unit 200 and the parent unit 200 is responsive to receiving a signal representative of an audible sound transmitted from the baby unit 300. The parent unit 200 includes a microphone 270 that receives audible signals from a user and a speaker 280 that produces audible sound received from the baby unit 300. Similarly, the baby unit 300 includes a microphone 370 that receives audible signals from the baby and a speaker 380 that produces audible sound received from the parent unit 200.
As mentioned above, the baby unit 300 also includes a soothing unit 400. The soothing unit 400 produces a variety of soothing lights and/or sounds to soothe a child located near the baby unit 300. The soothing unit 400 may be actuated by a control signal received from the parent unit 200. Optionally, the soothing unit 400 may be actuated locally (e.g., by a switch on 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 42A and video content 42B. Audio content 42A can include, for example, in either digital or analog form, musical tones (which can be combined to form musical compositions), speech (recorded or synthesized), or sounds (including recorded natural sounds, or electronically synthesized sounds). Video content 42B can include, for example, in analog or digital form, still or video images, or simply control signals for activation of lamps or other light-emitting devices.
The output content can be communicated to an infant for hearing or viewing by baby unit output generator 44, which can include an audio output generator 45 and a video output generator 46. Audio output generator 45 can include an audio signal generator 45A, which converts audio output content 42A into signals suitable for driving an audio transducer 45B, such as a speaker, for converting the signals into audible sound waves. Video output generator 46 can include a video signal generator 46A, which converts video output content 42B into signals suitable for driving a video transducer 46B, such as a display screen, lights, or projected images, for converting the signals into visible light waves. Video output generator 46 can also include moveable physical objects, such as miniature figures, to produce visual stimulus to the infant. The selection of the output 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 20R, 20L, for accessing the output content to be output and activating the output generator 44 to operate on the selected and accessed output content 42. The operation of control module 31 can be governed by control logic 32, which can be, for example, computer software code. The video and audio output can be coordinated to enhance the pleasing effect.
Local user input module 20L includes a mode selector 22 and a local actuator 24. Mode selector 22 allows the user to select from among various output modes of soothing features for viewing and/or hearing by the baby. Illustrative output modes include combined video and audio output, audio-only output, and video-only output. For example, one selected output mode could include both audio content 42A, which can include a set of musical tones and a set of sound effect segments, and video content 42B, which can include a selected sequence of illumination instructions for lamps or dynamic images. The local actuator 24 allows the user to input “start,” or “stop,” commands via, for example, mechanical contact switches. Local actuator 24 is physically located on the baby unit 300.
Control logic 32 includes sets of sequences in which the musical tones can be output to produce recognizable tunes. A program can include a predetermined sequential output of the sets of tone sequences, producing a sequence of musical tunes. Lamps can be illuminated in response to a set of illumination instructions correlated with the playing of the tunes. A program may also include output of a single one of the sets of tone sequences, producing one musical tune, also with coordinated lights. A sound effects program can include output of a single one of the sound effect segments.
Remote user input module 20R includes remote actuators 26a and 26b, by which the user can provide input to control module 31 to access the selected output content and to initiate its output. Remote actuator 26a also allows the user to input “start,” or “stop,” commands via, for example, mechanical contact switches. Remote actuator 26b allows the user to transmit spoken words through a microphone, to ultimately be transmitted to the baby unit 300. Remote actuators 26a, 26b include a transmitter portion 27 physically located on the parent unit 200. A corresponding receiver portion 28, which receives signals from remote actuators 26a, 26b, is physically located on the baby unit 300. A command signal can be communicated between the transmitter portion and the receiver portion without a physical link, such as an electromagnetic signal (including infrared and radio frequency) or an acoustical signal (including ultrasonic), or with a physical link, such as an electrical signal carried by a conductor coupling the transmitter portion and the receiver portion.
The transmitter 27 is capable of receiving verbal input 27A from the user (e.g., a parent) and has a signal generator 27B to generate a signal that is transmitted to receiver 28 in the baby unit 300. The receiver 28 processes the received signal and outputs an audio signal representative of the user's spoken words. The audio signal is output by audio output generator 45 that includes signal generator 45A, which converts the received audio signal to signals suitable for driving the audio transducer 45B.
The baby unit user input module 30 includes a transmitter portion 37 that receives a verbal input 37A from the user (e.g., a crying infant) and has a signal generator 37B to generate a signal that is transmitted via transducer 37C to a receiver 58 in the parent unit 200. The receiver 58 processes the received signal and outputs an audio signal and a corresponding video signal. The receiver 58 includes a transducer 58A and a processor 58B. The output 50 can include an audio output generator 55 and a video output generator 56. Audio output generator 55 can include an audio signal generator 55A, which converts the received signal to signals suitable for driving an audio transducer 55B, such as a speaker, for converting the signals into audible sound waves. Video output generator 56 can include a video signal generator 56A, which converts the received signal into signals suitable for driving a video transducer 56B, such as an array of LEDs. The array of LEDs is illuminated in such a manner that the number of LEDs that are illuminated corresponds to the strength of the signal received from baby unit user input module 30.
To use the baby monitor system 100, a user places the infant to be soothed within an operative range of the output generator 44. The user selects an output mode for the soothing features with mode selector 22, and issues a “start” command via either local actuator 24 or remote actuator 26a. The control module 31 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 26a 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 fictional elements and the parent and baby units is illustrated in
As shown in
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.

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
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 SW3A as can be seen in
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 SW3 (see
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
The parent unit 200 may be turned on, and the volume may be adjusted; via power switch 212 (implemented as switch SW2 in
The parent unit 200 also includes remote user input module 20R, 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 20R is implemented as remote soothing actuator 220 (implemented as switch SW3 in
When the talk actuator 230 (switch SW5) 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 SW3 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
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
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, 350, respectively. In this manner, the output of the speaker 280, 380 would be less likely to interfere with user input at the parent unit 200 or the baby unit 300.
The various features of the invention have been described in relation to baby monitors. However, it will be appreciated that many of the features, such as the visual displays, the soothing unit, the remote control operation, and the two-way communication can be implemented on a variety of other children's products such as crib toys, stroller attachments, playpen attachments, etc. Moreover, variations and modifications exist that would not depart from the scope of the invention. A number of these variations have been set forth above, however, additional variations can be contemplated by those skilled in the art.
