the disclosed device uses pulses of light directed at the eyes of a subject to awaken them from sleep . although the device can be in any design or format that accomplishes the needed impulses to simulate a subject from sleep , a mask is a preferred design . the mask has a band to attach the mask to the face of the user . the shape of the mask is designed to house the electronics , fit comfortably , block light from outside and be stylish . various materials can be used to make the mask . the material should be sturdy , lightweight , durable , and block light . the side of the mask facing the user can have a light weight , soft foam that rests against the user . the foam has holes for the light source , and plane polarizing , uv light blocking lenses , which provides a distance from mask and eyes , and comfort for the user . the mask can be used with or without the control center . the control center can be easily removed from the mask when it needs to be replaced due to wear and tear . a replacement mask will accept the original control center and the original worn out mask can be thrown away . a led array made of a variety of colors is arranged and connected to a logic chip . the logic chip is able to program the array to turn on at a set time , and have a specific color , pulsation rate , and intensity . the chip will have memory to save routines . the chip also may provide a random surprise wake up signal with unknown color , intensity and pulsation rate . a battery source , a screen , and connections to all components will be housed in the control center . the case will be made from a light weight material . the control center is able to be separated from the mask . the case can be opened for programming and easily closed after programming . an alternative to the mask design of the disclosed device is a pillow unit with the previously described components . the foam is large enough the fit inside a typical pillow case and the control center is covered to protect its electronic components . the electronics is housed within the pillow with the leds embedded in the pillow . the leds are covered with a plane polarizing uv light blocking lens , if needed . another alternative design to the disclosed device is a bedside apparatus . it can be attached to a head board on a bed or on a nearby table . fig3 shows the light emitting device as a face mask with the band 2 connected to the mask 1 by a loop 4 passing through the mask 1 . the end of the band is retained by an attachment site 3 . contained within the mask 1 is a case 7 . fig4 shows the light emitting device as a face mask with the case 7 flipped open to show the contents . the case 7 has on the top cover a screen 8 , a logic chip 9 , a battery 10 , and the controls ( control center ) 11 . the mask 1 has the light source arrays 12 underneath the case 7 cover . fig5 shows the light emitting device as a face mask with the inside ( surface touching face ) of mask 1 . the inside of the mask 1 has a layer of soft material or foam 5 . over the area where the person &# 39 ; s eyes would be located are lenses 6 . fig6 shows a close - up of the case 7 . the top of the cover has the screen 8 , logic chip 9 , battery 10 , and controls ( control center ) 11 . the bottom of the case 7 has the light source arrays 12 . fig7 shows the light emitting device as a pillow covered with a layer of soft material or foam 5 . the pillow has a case 7 containing the controls ( control center ) that regulates the light source arrays 12 on the outside of the pillow . fig8 represents a smart phone with icons on the display panel . the tapping the icon selects the claimed program and allows the user to change parameters ( light frequency ( color ), pulse rate , light intensity , time of onset , time duration between renewed activation , etc .) of the light awakening process . fig9 represents a smart tablet with icons on the display panel . the tapping the icon selects the claimed program and allows the user to change parameters ( light frequency ( color ), pulse rate , light intensity , time of onset , time duration between renewed activation , etc .) of the light awakening process . the disclosed device and method use the combination of wave length , duration , initiation of onset , termination of duration , pulse rate , and intensity to awaken a sleeping animal , including humans ; and it is the specific combination of these features that achieves the disclosed result of awakening a sleeping animal . the combination of features should be viewed as 3 -, 4 -, 5 - or 6 - dimensional spaces where each value corresponds to a specific point in space ( fig1 ). the effect of the light to awaken a subject requires that the disclosed parameters exist at the same time within the boundaries of the effective zone . the light cannot be considered as if it were three separate components in a machine . each combination of the parameters of light — e . g . wavelength , intensity ( lux ) and pulse rate — produces a unique response in the brain . this feature is best illustrated by fig1 . a single type of light is represented by a single point in the 3d space of x ( wavelength ), y ( lux ) and z ( pulse rate [× 1 , 000 pulses / hour ]). this graph illustrates the disclosures in jaillet &# 39 ; 977 and searfoss et al . ( us 20050248962 ), and compares them to the claimed light in claim 1 . the box along the x - axis illustrates a range of light [ 400 - 700 nm × 0 - 4 , 000 × 2 - 36 , 000 ]. the plane near the top of the z - axis shows the disclosed values in jaillet &# 39 ; 977 [ 390 - 750 × 2 , 500 - 10000 × 144 , 000 ]. the point that would represent the disclosure in searfoss &# 39 ; 962 cannot be shown in this graph because it is too small [ 390 - 750 × ø × 0 ] since searfoss &# 39 ; 962 does not disclose a lux value and the light is constant ( 0 pulses / hour ). an examination of the graph shows there is no overlap between the disclosed light and a light from a combination of jaillet &# 39 ; 977 and searfoss &# 39 ; 962 . there is no overlap between the disclosed light and this combination . the true test of evaluating different light sources with different parameters is to find a light source that has some of the disclosed parameters at the same time ( i . e ., there would be overlap in a 3d graph ). for example , a light intensity disclosed for the treatment of seasonal affective disorders ( sads ) would not suggest to a person skilled in the art that this treatment could be used to awaken a sleeping subject . there is no known correlation that would suggest to a doctor or a person working in sleep research to use a method to awaken a sleeping person that was developed for the treatment of a person with sads . additionally , some of these devices make dubious claims as to their effectiveness for treating neurological symptoms . the device and methods disclosed in jaillet &# 39 ; 977 to “ reconfigure or redirect nervous impulses to treat the symptoms of dyslexia , attention deficit disorder ( add ) and attention deficit hyperactive disorder ( adhd )” do not have strong medical evidence to support that they are an effective treatment for these ailments . these devices or methods lack endorsements by the american academy of pediatrics or the american psychiatric association . the neural pathways to the parts of the brain involved are not reached by the optic nerve and light is not all correlated with therapeutic gains in these diseases . even if this device and method worked for these symptoms they would not be appropriate for awakening a person from sleep . there is no correlation between a person with these disorders and a normal healthy person sleeping . an important aspect of the disclosed devices and methods is that a person is more alert and cognitively functioning faster with the proper light stimuli rather than with a sound alarm . vandewalle et al . 2011 found when compared to longer wavelength light , shorter wavelength light exposure increases ongoing nonvisual cognitive activity in subcortical and cortical brain areas . compared with green light , 1 minute of low intensity blue light was able to significantly increase brain activity in a widespread set of higher order cortical areas , including the frontopolar , lateral prefrontal and premotor cortex , intraparietal sulcus , insula , cerebellum , and thalamus , which are all known to be involved in executive control and working memory . the rate of pulsating the light is important to the disclosed devices and methods since science has proven in humans and animals this stimulation is superior to continuous light stimulation . it has been reported in studies of nocturnal animals that the mammalian circadian system is responsive to brief exposures of light . nelson and takahashi 1991 demonstrated that pulses of bright light as short as 3 seconds produced measurable phase shifts in the golden hamster . they also showed that extending the duration of the stimulus beyond 5 minutes produced little additional phase shift . gronfier et al . 2004 demonstrates that a single sequence of intermittent bright light pulses can phase delay the human circadian pacemaker and shows that intermittent pulses of light has a greater resetting efficacy on a per minute basis than does continuous exposure to light . medical training and experience with patients were used to develop the disclosed methods and devices that use the method . the specific characteristics and qualities of light have a profound effect on the human brain and a human &# 39 ; s behavior . light with the disclosed light parameters produced superior results . up to the
