1. Field of the Invention
The present invention relates generally to entertainment devices and more particularly to entertainment devices convertible between multiple configurations.
2. Discussion of the Related Art
Entertainment devices for infants such as mobiles and light projectors are known. Mobiles are typically attached to an infant's crib and are often removed when the infant reaches a certain age. Once removed, the mobile has little or no utility. Light projectors are often placed adjacent an infant's crib to project images on the ceiling to entertain the infant positioned in the crib. While these devices can be used for a greater period of time because of their location outside the crib, their entertainment value diminishes as the child gets older.
What is needed is an improved entertainment device that can be used to entertain an infant and can be converted to perform a useful function when no longer being used to entertain the infant.
The present invention provides an apparatus having a support arm, and a base coupled to the support arm to maintain the support arm in an upright orientation. The base is moveable between a first orientation in which the base is coupleable to a vertical surface, and a second orientation in which the base can rest on a horizontal surface. A light source is coupled to the support arm. A mobile may also be coupled to the support arm, whereby when the base is in the first orientation, the apparatus can be coupled to a crib rail to function as a crib mobile, and when the base is in the second orientation, the apparatus can rest on a horizontal surface to function as a lamp.
These and other aspects of the present invention will become apparent from the following drawings and description.
The present invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
Several embodiments of a convertible entertainment device 10 incorporating the principles of the invention are shown in
The entertainment unit 100 includes a light source 180 that projects on a surface opposite the light source. The opposite surface may be a wall or a ceiling depending upon the configuration of the entertainment device 10 (as will be described in detail below). A second light source 190 also projects on a surface spaced from the entertainment unit 100 (preferably a surface other than the surface illuminated by the first light sources 180. The light source 180, 190 may be illuminated by a single light bulb that illuminates each light source or multiple light bulbs.
An article 170 may be suspended from the entertainment unit 100 via a detachable support 160. The detachable support may be removed from the entertainment unit (as indicated by the “X” in
When the base 500 is in its first orientation, the entertainment device 10 can be coupled to a vertical surface, such as a crib rail or a wall adjacent the crib, to function as a crib mobile. When the base 500 is in its second orientation, the entertainment device 10 can rest on a horizontal surface S to function as a lamp. Regardless of orientation, the entertainment unit 100 is configured to extend above a surface S, whether it be a crib mattress or a desk surface as described above.
It is also possible to change the orientation of the entertainment device by repositioning the entertainment unit with respect to the support arm 300 and/or repositioning the support arm 300 with respect to the base.

Output block 40 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 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 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 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 or lights, for converting the signals into visible light waves. Video output generator can also include moving physical objects, such as miniature figures, to produce visual stimulus to the infant. The selection of the output content, and the performance attributes of the output generators, should be driven by the goal of generating output that is appealing or soothing to an infant. Audio pressure levels should be selected to calm, rather than startle, the infant. Audio content should be pleasing, comforting, and/or rhythmic or melodic.
Control block 30 controls output block 40, selecting the output content to be output and activating the output generator 44 to operate on the selected output content. The operation of control block 30 can be governed by control logic 32, which can be, for example, computer software code. Control logic 32 can select content to be output repetitively or non-repetitively, and/or randomly or in fixed sequences. The video and audio output can be coordinated to enhance the pleasing effect.
User input block 20 includes a mode selector 22, a local actuator 24, and a remote actuator 26, by which the user can provide input to control block 30 to influence the selection of output content and to initiate its output. Mode selector 22 allows the user to select from among output modes. Illustrative output modes include variations of combined video and audio output. For example, the audio content 42A can include a set of musical tones and a set of sound effect segments, and the video content can include a selected sequence of illumination instructions for lamps. Control logic 32 includes sets of sequences in which the musical tones can be output to produce recognizable tunes. Various modes of light operation (i.e., direction of light transmission) may be selected. 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.
The local and remote actuators 24 and 26 allow the user to input simple commands such as “start,” “stop,” or “repeat” via simple mechanisms such as mechanical contact switches. Local actuator 24 is physically proximate to the output block 40. In contrast, remote actuator 26 includes a transmitter portion 27 that can be operated from a position physically remote from the output block 40, and a receiver portion 28 physically proximate to the output block 40. 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 (including ultrasonic), or with a physical link, such as an electrical signal carried by a conductor coupling the transmitter portion and the receiver portion.
In the illustrated embodiment, a wireless short-wave infrared system is used for communication of command signals. The transmitter 26 therefore includes an input button 27A (which the user can press to initiate a command signal), a command signal generator 27B activated by the button 27A, and an infrared emitting transducer (an LED) 27C. Receiver 28 includes an infrared receiving transducer (a photosensor) 28A and a processor 28B to interpret signals received by transducer 28A.
User input block 20 further includes two feedback mechanisms for the user. The first is a beacon light 29A associated with, and physically proximate to, receiving transducer 28A. Beacon light 29A is illuminated (for example, in a flashing or intermittent fashion) when the system is active and ready to receive command signals from the remote actuator 26. This gives the user a visual cue to the system's active state, and further helps the user to locate the system in a darkened room. The second feedback mechanism is a remote signal light 29B associated with, and physically proximate to, transmitting transducer 27C. Signal light 29B is illuminated when the command signal generator 27B is generating command signals, to provide visual confirmation to the user that actuation of the input button 27A has resulted in the production of a command signal.
To use the entertainment device, a user places the output generator and the infant to be soothed within an operative range of one another. The user selects an output mode with mode select 22, and issues a “start” command via local actuator 24 or remote actuator 26. The control 30 receives the mode selection and the start command, selects the corresponding output content, and activates the output generator 44 to generate the selected output content. Use of the remote actuator to issue commands allows the user to be positioned remote from the infant, so that the soothing output can be generated while minimizing the risk that the user will disturb, or attract the attention of, the infant.

Detachable supports 160 are releasably coupled to rotating member 125. When the entertainment device 10 is in its first orientation, the detachable supports 160 are coupled to, and operate with, rotating member 125 to function as a mobile. When the entertainment device 10 is placed in its second orientation, the detachable supports 160 may be removed from rotating member 125 so as not to interfere with the light that is projecting downwardly on the surface opposite the entertainment unit 100.
The releasable coupling of detachable supports 160 and rotating member 125 can be achieved with a variety of techniques. In the embodiment illustrated in
It will be appreciated that the detachable supports 160, 160′ may take multiple configurations. For example, the detachable supports 160, 160′ may support an article 170 by a string as in a conventional mobile or the article 170 may be fixedly coupled to the end of the support post 160, 160′.

The audio signal generator 46a, video signal generator 45A, output content 42, and control block 30 are all implemented in the illustrated embodiment on controller 130, which is a model SN66012 available from Sonix Corporation. The audio content 42A is stored in digital form in a memory portion of controller 130. Audio content 42A includes sets of tone identifiers arranged in sequences corresponding to musical tunes. Seven such sets of tone identifiers are stored, allowing generation of ten musical tunes, such as Brahm's Lullaby, Twinkle Twinkle Little Star, Moonlight Sonata, Ocean Sounds, Night Time Sounds, etc. Controller 130 has the built-in capability to produce tones identified by the tone identifiers, and to drive speaker 191 to the desired sound pressure level.
The physical implementation of user input block 20 will now be described. Local actuator 24 is implemented as entertainment unit input switch SW4 (illustrated in
Mode selector 22 is implemented as mode select switches SW2 and SW3 (illustrated in
Remote actuator 26 is implemented as a short-wave infrared remote control system with components in the entertainment unit 100 and in the remote unit 200. The receiver 28 is implemented as remote receiver, with a photo sensor 822 (corresponding to receiving transducer 28A), which converts incident light in the short-wave infrared spectrum into electrical signals supplied to controller 130, which includes the function of command signal processor 28B to process the electrical signals received from photosensor 822 and determine whether the received IR signal is a command signal from remote transmitter 27.
As shown in
Power for the electronic components of entertainment unit 100 is supplied by entertainment unit power supply 183, which in the illustrated embodiment consists of batteries (four C-sized cells), which are housed in battery compartment 575 and accessed via battery cover 576. Wires are channeled through support arm 3400 and conduit 141 to drive the electronic components.
Remote transmitter 27 of remote actuator 26 is implemented as an infrared transmitter, which is housed in remote unit 200. The remote unit 200 is similar to the remote unit described in U.S. Pat. No. 6,116,983, which is assigned to the assignee of the present invention and is incorporated herein by reference in its entirety. The infrared transmitter includes a remote controller 315 (corresponding to signal generator 27B) that generates an electronic signal that is communicated to transmission LED 840 (corresponding to transmission transducer 27C), which in turn generates an IR command signal. In the illustrated embodiment, the remote controller 815 is a 14 stage binary counter model 74HC4060, which is a standard part commercially available from a variety of sources.
Operation of controller 815 is initiated by the user by actuating remote input switch SW1 (corresponding to input 27A), which in the illustrated embodiment is a momentary contact switch with a large circular remote button 821.
The components of the infrared transmitter 810 are housed in remote housing 210 of remote unit 200. The remote unit 200 includes a remote unit housing 210, which is formed of a housing top 212, and a housing bottom (not visible in
An IR-transparent window (not shown) is also trapped between the housing top 212 and housing bottom. Transmission LED 840 is mounted in the housing behind the window. The remote unit uses batteries for a power supply. Remote button 821 is mounted in housing top 212. Indicator light 251 (corresponding to light 29B) is mounted in housing top 212 in front of button 821. A power supply (two AA batteries, in the disclosed embodiment) is also contained in a battery compartment of housing 210, and are accessed by a removable battery cover as would be apparent to those skilled in the art.
The remote unit 200 produces IR control signals for activating the entertainment unit 100 at a remote distance, preferably at a minimum of 20′ (6 m) from the remote receiver in normal household lighting conditions.
As stated earlier, the entertainment device 10 is activated by receiving the IR control signal from the remote unit 200 (the entertainment device can also be activated by pressing the manual activation button 161). The control signal transmitted from the remote unit 200 is detected by a remote receiver with a photo sensor for detecting short-wave IR signals modulated on a 37.9 kHz carrier frequency.
The operation of the entertainment device 10 will now be described with reference to
The IR command signals must be received while the entertainment unit 100 is active. Controller 130 includes an internal timer by which it can monitor the time that has elapsed since a command signal was last received. If the elapsed time exceeds an established standby period, the receiver 820 portion of the remote control will shut down to conserve power. Once powered-down, the entertainment unit 100 will not produce output in response to a second control signal but will continue to respond to a user pressing the manual button 161. Pressing the manual button 161 will also power-on the remote receiver 820, making the entertainment unit 100 “remote ready.” The entertainment unit will also become “remote ready” if the user selects a new output mode, other than “off,” using the mode selector 171, 172. Once the entertainment unit 100 is “remote ready,” the user can thereafter activate the entertainment device via an IR command signal. There is no output generated when the mode selector switches 171, 172 are set to “off.”
In the illustrated embodiment, the various housing components, buttons, etc. are formed of plastic materials, but any other material suitable for use can be used.
Although the disclosed audio generator has a fixed output volume, it is contemplated that a volume control could be added to permit the user to vary the output.
The power supply is disclosed as batteries, but it is contemplated that alternative sources of power could be used, including household AC power. Moreover, it is contemplated that if AC power were used, the receiver portion of the remote could always be “remote ready” since there would not be the same level of concern with conserving power.
The remotely controlled output, as disclosed, uses a simple, one-function remote, however, other remotes with greater functionality are contemplated. For example, it is contemplated that remotes with buttons for remotely selecting output modes or remotes which transmit Radio-Frequency (RF) verses Infra Red (IR) signals.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
The previous description of the preferred embodiments is provided to enable any person skilled in the art to make or use the present invention. While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
