Title: System For Aural Delivery of Light And Sound

Description:
TECHNICAL FIELD 
     The present invention generally relates to a system for aural delivery of light and sound, and specifically to a system that delivers light and sound at frequencies between 2 and 45 Hz, including binaural generated beat sound frequency in this range. 
     BACKGROUND 
     Healthy lighting and sound can enhance mood, energy, sleep, and focus. Healthy lighting and sound have been shown to help with common problems such as winter blues, sleep disorders, light deprivation, jet lag, shift work, memory conditions, and other symptoms alleviated by exposure to healthy light and sound. 
     Conventional healthy lighting devices, which resemble lamps or tablets, typically deliver light optically, i.e., through the eyes. Such conventional systems suffer from known problems. The amount of light received by the eyes is low, and receptive eye surface area is a function of where the user sits in relation to the light. In addition, conventional healthy lighting devices may distract or annoy others if used in dark rooms. Therefore, users desiring to use healthy light or other stimuli to affect the brain require a different approach. Conventional healthy lighting devices also do not include speakers. 
     Furthermore, conventional healthy lighting systems only allow the use of light at a single frequency. Moreover, conventional healthy lighting systems are often difficult to take and use on travels since they must be plugged into a wall. In this way, users may struggle with their availability for use on a plane or train (for example). 
     Furthermore, users of conventional healthy lighting and sound systems often do not use their devices for sufficient time. 
     Finally, there is no way to adjust and/or personalize conventional healthy lighting and sound systems to ensure desired stimuli are provided. 
     U.S. Pat. No. 9,258,642 describes an “accessory” that “comprises first and second signal conveyers for conveying electrical audio signal driving audio transducers and electrical optic signal driving optical radiation sources, respectively.” A main concern of the &#39;642 Patent is for users to receive optical radiation while simultaneously listening to music. However, the &#39;642 Patent is silent regarding aspects of the present invention, including delivering light and sound at a specific frequency. 
     U.S. Pat. No. 10,265,497 described inducing synchronized gamma oscillations in the brain by using “stimulus-emitting device to emit a stimulus (e.g., light, sound, and/or haptic) at a frequency (e.g., about 40 Hz).” However, the &#39;497 Patent is silent regarding delivering light aurally to increase desired effects, let alone delivering both light and sound aurally. 
     SUMMARY 
     Delivery of healthy lighting and/or sound aurally solves many of the problems identified above. 
     An object of the invention is to deliver light and sound aurally at specified frequencies, including between 2 Hz to 45 Hz. 
     A further object of the invention is to use binaural delivery which can significantly ameliorate the distraction and annoyance often experienced with “pure” 40 Hz tones. 
     A further object of the invention is to house a speaker and the light module in a small, travel-friendly housing. 
     It is a further object of the invention for the housing to be headphones or earbuds. 
     It is a further object of the invention to control the healthy lighting and sound system using a smartphone or other portable computing device. 
     It is a further object of the invention to reduce energy usage by employing LED lights in the system. 
     It is a further object of the invention to provide a timer for the healthy lighting and sound system. 
     It is a further object of the invention to use the healthy lighting and sound system with an EEG machine to the frequency of light or sound based on EEG measurements. 
     It is a further object of the present invention to provide a system where the emitted light is of sufficient intensity and fluence to penetrate the skull and stimulate underlying tissue. 
     In one aspect of the invention, a system for aurally delivering light and sound is provided having a computer in communication with a light module and a speaker, software executing on said computer for driving the speaker to produce sound, and software executing on said computer for driving the light module to produce light at a frequency of 2 Hz to 45 Hz. In another aspect of the invention, software executing on said computer drives the speaker to produce sound at a frequency of 2 Hz to 45 Hz. In another aspect of the invention, the sound is binaural beats generated by driving stereo speakers. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is a schematic diagram of the presently disclosed system. 
     
    
    
     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , the present disclosure describes a system  10  for aural delivery of light and sound. 
     The system  10  includes a computer  1 . The computer  1  may be a processor, remote computer, computer server, network, smart phone, tablet, or any other computing resource. The computer  1  may be able to receive user input from an integrated or connected component. The computer  1  may receive input  31  from a user  3  via an integrated or connected component such as a keyboard, mouse, touchpad, button, or other known device. In an embodiment, the computer  1  is a smartphone which runs a mobile application to perform the functionality described below. 
     The computer  1  may also be in communication with a database  2 . The database  2  may be a storage drive or array accessible to computer  1 . The database  2  may store information regarding the system  10 , including settings for the system  21  and measurements  51 . 
     The computer  1  may also be in communication with a timer  4 . Timer  4  may include a computer, laptop, smartphone, tablet, or other electronic device capable of transmitting data to the computer. In some embodiments, timer  4  may be a component of computer  1 . The timer  4  provides a usage time  41  to the computer  1 . The usage time  41  may be based on an actuation received from a user of the system  10 . The usage time  41  may track the amount of time the system  10  has output light and/or sound. 
     The computer  1  may also be in communication with one or more measuring devices  5 . The measuring device  5  may be a device that monitors and reports on body measurements. For example, the measuring device  5  may be an EEG, ECOG, or other device capable of measuring electrical activity in the brain. The measuring device  5  may also be a heart rate monitor or other device that can be used to measure the relaxation or exertion of an individual. The measuring device  5  provides measurements  51  to the computer  1 , which the computer  1  may store on the database  2 . The measurements  51  may be stored in a manner correlating them with the user of the system. 
     The computer  1  may also be in communication with light module  6 . Light module  6  may be an LED, multiple LEDs, or known light sources. The light module  6  may produce light in the visual spectrum, near-infrared spectrum, or other known spectrums. The light module  6  may be capable of adjusting the light emitted. For example, frequency  61 , wavelength  62 , intensity, fluence, and other properties may be adjustable by the light module  6 . 
     The computer  1  may also be in communication with speaker(s)  7 . The computer may be capable of adjusting speaker(s)  7 . For example, frequency  71  and volume  72  may be adjustable by the computer. Further, in the stereo configuration each speaker may play the same or different pure tone frequencies and volumes or music. 
     When system  10  is powered, it may output light from light module  6  and/or sound from speaker(s)  7 . An input  31  to the computer  1  may specify a frequency  61 ,  71 , wavelength  62 , and/or volume  72  of the light and/or sound to be output. Preferably, the system  10  generates light and/or sound that are output at frequencies between 2 and 45 Hz. Also preferably, the system  10  generates light that has a wavelength of approximately 900 nm. The input  31  may specify that the light and sound are output at the same frequency, or different frequencies. 
     Regarding the sound output from speaker(s)  7 , the frequency can be produced directly by the speaker. Alternatively, the frequency can be produced using known methods such as binaural beats. Stereo earphones or headphones are usually required to produce the binaural beat effect. However, stereo speakers may not be required if simple beat production is used. 
     The frequency  61 ,  71 , wavelength  62 , and/or volume  72  may be specified as a time-based series. For example, the input  31  may specify that the output should be 20 Hz for five minutes, followed by 30 Hz for 10 minutes. The input  31  may also specify other properties for the light and/or sound such as intensity and fluence. Computer  1  transmits the specified frequency  61 ,  71 , wavelength  62 , and/or volume  72  and any other properties to the light module  6  and speaker(s)  7  in a manner appropriate to generate the output light and/or sound. 
     A timer  4  may send the computer a usage time  41  regarding the amount of time the system  10  has been in use. The computer system  10  may stop all output of light and/or sound after the usage time  41  reaches one hour. 
     The user input  31  may include an indication for the computer  1  to store the input for future recall. The computer may then convert the input  31  to settings  21 , and store the settings  21  on the database  2 . The settings  21  may contain stored frequency  61 ,  71 , wavelength  62 , and/or volume  72  information. Once stored, the user input  31  may specify that stored settings  21  may be used to control the system  10 . Computer  1  and/or database  2  may be pre-loaded with settings  21 . 
     The computer  1  may receive measurements  51  from measuring device  5 . The computer  1  may vary the frequency  61 ,  71 , wavelength  62  volume  72  or other property based on the measurements  51  received. In some embodiments, the frequency  61 ,  71 , may be varied in increments of 5 Hz. For example, in the case of an EEG  4 , the computer may vary frequency  61 ,  71 , wavelength  62  and/or volume  72  such that a stable electrical pattern is measured by the EEG  4 . For example, the output light frequency  61  may be varied to find where the brain&#39;s electrical activity at 40 Hz is the greatest. Other frequency responses may be measured and used by the computer  1  to determine optimized outputs. The optimized output may be stored by the computer  1  on the database  2  as a setting  21  for future use. 
     The computer may also retrieve stored measurements  51  from the database  2 . For example, the computer  1  may store the light frequency  61  that produces the greatest 40 Hz response in the brain to be retrieved the next time the user uses the system  10 . Later, when the system  10  is to be used again, it can allow the user  3  to specify via input  31  that the computer  1  should base the output of light module  6  and/or speaker(s)  7  on stored measurements  51 . 
     The system  10  is advantageously embodied in a set of headphones, and more particularly ear buds, containing a light module  6  and speaker  7  for each ear. The computer  1 , database  2 , and timer  4  are advantageously embodied as a smartphone.
