DETAILED DESCRIPTION

(10) The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed, unless expressly stated otherwise. A and an as used herein indicate at least one of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word about and all geometric and spatial descriptors are to be understood as modified by the word substantially in describing the broadest scope of the technology. About when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by about and/or substantially is not otherwise understood in the art with this ordinary meaning, then about and/or substantially as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.

(11) Although the open-ended term comprising, as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as consisting of or consisting essentially of. Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.

(12) As referred to herein, disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of from A to B or from about A to about B is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.

(13) When an element or layer is referred to as being on, engaged to, connected to, or coupled to another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being directly on, directly engaged to, directly connected to or directly coupled to another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., between versus directly between, adjacent versus directly adjacent, etc.). As used herein, the term and/or includes any and all combinations of one or more of the associated listed items.

(14) Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as first, second, and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

(15) Spatially relative terms, such as inner, outer, beneath, below, lower, above, upper, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as below or beneath other elements or features would then be oriented above the other elements or features. Thus, the example term below can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

(16) The present technology relates to a face plate 100, electrical device recognition safety system 200, an electrical device recognition safety kit 300, and method 400 of making a wall mounted electrical device safer and more easily identified, shown generically in FIGS. 1-7. Advantageously, the face plate 100 and its use on an electrical receptacle box 101 allows for a generic electric device 103, such as an electrical outlet 105, light switch 107 or on/off switch 109, to be more easily visible. As such, the face plate 100 can provide a safety advantage for the elderly and those with low vision by making the face plate more visible on a wall.

(17) As shown in FIG. 6, the face plate 100 can be secured onto an electrical receptacle box 101. With reference to FIG. 1, the face plate 100 can include a plate body 102 having an opening 104 and a plurality of zones 106 that surround the opening 104. The opening 104 can be configured to provide access to a portion of the electrical device 103. The plurality of zones 106 can include a first zone 108 and a second zone 110. The first zone 108 can have a first visual contrast with the second zone 110. As used herein, the terms visual contrast and contrasting can be defined as meaning the state of being strikingly different from something else in juxtaposition or close association, or the use of opposing elements, such as colors, forms, or lines, in proximity to produce an intensified effect in visual appearance. To this point, the first zone 108 and the second zone 110 can have an interface 111 where an inner perimeter 113 of the first zone 108 and an outer perimeter 115 of the second zone 110 meet and are the same in shape and dimension. The interface 111 can create a distinction between the first zone 108 and the second zone 110. The distinction can be a feature of the visual contrast. The visual contrast can be defined by an inherent value associated with the mode of contrast selected, for example, color or lighting intensity.

(18) It should be appreciated that where the mode of visual contrast is color, the inherent value employed to define the contrast is a color contrast ratio. For example, the color contrast ratio can have a value equal to or greater than 4:1 in at least a few instances, equal to or greater than 5.5:1 in at least some instances, and equal to or greater than 7:1 in most instances. The color intensity contrast ratio can be determined by comparing the relative luminance of the lighter color to the relative luminance of the darker color.

(19) It should also be appreciated that where the mode of visual contrast is lighting intensity, the inherent value employed to define the contrast is a lighting intensity contrast ratio. For example, the lighting intensity contrast ratio can have a value equal to or greater than 2:1 in at least a few embodiments, equal to or greater than 3:1 in at least some embodiments, and equal to or greater than 4:1 in most embodiments. The light intensity contrast ratio can be determined by comparing the lumens of the higher lighting intensity to the lumens of the lower lighting intensity.

(20) With reference to FIG. 1-5 and as explained hereinabove, the first visual contrast between the first zone 108 and the second zone 110 can be created by a difference in color, a difference in lighting, a difference in both color and lighting, or any difference that could be selected by a skilled artisan within the scope of the present disclosure, each shown in FIGS. 1-4 where a difference in color is depicted in FIG. 1 with the first zone 108 having no crosshatching and the second zone 1120 having cross hatching. For example, the first zone 108 can include a first color 112 and the second zone 110 can include a second color 114, depicted in FIG. 1 by crosshatching. The first color 112 and the second color 114 can be different such that a first visual contrast is created when the first color 112 and the second color 114 are disposed adjacent to one another on the face plate 100. A skilled artisan can select a suitable color for the first color 112 and the second color 114 such that there is contrast. Additionally, the first color 112 and the second color 114 can be selected to contrast with the color of the wall on which the face plate 100 is installed.

(21) As a further example and with continued reference to FIG. 2, the first visual contrast between the first zone 108 and the second zone 110 can be created by a difference in lighting intensity, depicted with crosshatching in FIG. 2. The first zone 108 can include a first lighting intensity 116 and the second zone 110 can include a second lighting intensity 118. The first lighting intensity 116 and the second lighting intensity 118 can be different such that the first visual contrast is created when the first lighting intensity 116 and the second lighting intensity 118 are disposed adjacent to one another on the face plate 100. Where there is a visual contrast created by lighting intensity, the lighting intensity can be supplied by an emanating light source 120. As a non-limiting example, the emanating light source 120 can be an LED light. A skilled artisan can select a suitable emanating light source 120 within the scope of the present disclosure. To this point, the plate body 102 can be formed from a translucent material 113, as shown in FIG. 5, to permit light from the emanating light source 120 to pass therethrough. Alternatively, and as shown in FIG. 4, the lighting intensity created by the emanating light source 120 can pass through the plate body 102 via an aperture 122 in the plate body 102.

(22) With continued reference to FIG. 4, the aperture 122 can be rectangular in shape. Alternatively, the aperture 122 can be circular, triangular, hexagonal, or any shape that can be confined within a perimeter of one zone of the plurality of zones 106. The aperture 122 can also be any size such that the aperture 122 is confined within the perimeter of one zone of the plurality of zones 106. A skilled artisan can select any suitable shape and size for the aperture 122 within the scope of the present disclosure. Additionally, the face plate 100 can include several apertures 122 within one zone of the plurality of zones 106. Further, the first zone 108, the second zone 110, and any additional zone within the plurality of zones 106 can all include apertures 122 configured to allow for light created by the emanating light source 120 to pass through the plate body 102.

(23) Alternatively, the lighting intensity can be supplied by a luminescent material disposed on or in the plate body 102. For example, the first zone 108 and the second zone 110 can be formed of the luminescent material with the concentration of the luminescent material in the first zone 108 differing from the concentration of the luminescent material in the second zone 110 to create visual contrast. In an alternative embodiment, the luminescent material can be disposed on the surface of the first zone 108 and the second zone 110 in different concentrations to create the first visual contrast. A skilled artisan can select a suitable concentration of luminescent material for the first zone 108 and the second zone 110 within the scope of the present disclosure. It should also be appreciated that the luminescence can be, but is not limited to, fluorescence, photoluminescence, electroluminescence, and phosphorescence. A skilled artisan can select a suitable form of luminescence within the scope of the present disclosure.

(24) As shown in FIGS. 2-3, the plurality of zones 106 can include a third zone 124. The third zone 124 can have a second visual contrast with the second zone 110. The visual difference between the second zone 110 and the third zone 124 can be created by a difference in color where the third zone 124 is a third color 126, shown in FIG. 3. In certain embodiments, the first color 112 and the third color 126 can be the same and the second color 114 can be different from the first color 112 and the third color 126, shown with crosshatching in FIG. 3. Alternatively, the first color 112, the second color 114, and the third color 126 can all be different colors. Further, the first color 112, the second color 114, and the third color 126 can be the same color but vary in intensity or hue such that a visual contrast is created. It should be noted that the first color 112, the second color 114, and the third color 126 can be selected to contrast with the color of the wall the face plate 100 is installed upon.

(25) As a further example, and with continued reference to FIG. 2, the visual difference between the second zone 110 and the third zone 124 can be created by a difference in lighting intensity where the third zone 124 is a third lighting intensity 128. In certain embodiments, the first lighting intensity 116 and the third lighting intensity 128 can be the same and the second lighting intensity 118 can be different from the first lighting intensity 116 and the third lighting intensity 128, shown with crosshatching in FIG. 2. Alternatively, the first lighting intensity 116, the second lighting intensity 118, and the third lighting intensity 128 can all be different lighting intensities. Further, the first lighting intensity 116, the second lighting intensity 118, and the third lighting intensity 128 can be the same lighting intensity but vary in brightness, saturation, or hue temperature such that a visual contrast is created.

(26) The face plate 100 can be any shape that fits over an electrical receptacle box 101. As non-limiting examples, the face plate 100 can be a rectangle, as shown in FIGS. 1-7, or other shapes including an X shape, a circle, or a triangle. A skilled artisan can select a shape for the face plate 100 within the scope of the present disclosure. Advantageously, the shape of the face plate 100 can signify as an identifier as to the type of generic electric device 103 in use. As a non-limiting example, a rectangular face plate 100 could signify a light switch 107 and an oval face plate 100 could signify an electrical outlet 105. Further, the first zone 108 and the second zone 110 can be any shape such that the interface 111 between the first zone 108 and the second zone 110 are substantially the same.

(27) The face plate 100 can be formed from any rigid material such as plastic, polyvinyl chloride (PVC), polycarbonate, nylon plastic, metal, wood, and composite material. A skilled artisan can select a suitable material for the face plate 100 within the scope of the present disclosure.

(28) The present disclosure also contemplates an electrical device recognition safety system 200. The system 200 can include an electrical receptacle box 101, a electrical device 103, and a face plate 100 as described hereinabove. The face plate 100 can be configured to be secured over the electrical receptacle box 101. Additionally, the face plate 100 can be configured to be secured to the electrical device 103 via a fastening means such as a screw, adhesive, or a snap. Advantageously, the face plate 100 can be installed upon or secured to a standard electrical receptable box 101 or electrical device 103 to allow for the face plate 100 to be retrofit to any electrical receptacle box 101 and/or electrical device 103 that is already installed. Desirably, additional installation is not required beyond securing the face plate 100 over the electrical receptacle box 101 or to the electrical device 103.

(29) The present disclosure contemplates an electrical device recognition safety kit. The safety kit can include a face plate 100, as described hereinabove, and a fastening means. As described above, the fastening means can be configured to secure the plate body 102 over the electrical receptacle box 101 and can include, but is not limited to, a screw, adhesive, or a snap. Advantageously, the safety kit can allow for a user to purchase the face plate 100 and fastening means to retrofit the face plate 100 onto a previously installed electrical receptacle box 101 or electrical device 103.

(30) The present disclosure further contemplates a method 400 for making a wall mounted electrical device safer and more easily identified. In a step 402, an electrical receptable box 101 can be provided. An electrical device 103 can be provided in a step 404. The electrical device 103 can include an electrical outlet 105, a light switch 107, or an on/off switch 109, as described hereinabove. A skilled artisan can select a suitable electrical device 103 within the scope of the present disclosure. In a step 406, a face plate 100 described hereinabove can be provided. The face plate 100 can include a plate body 102 having an opening 104 and plurality of zones 106 surrounding the opening including a first zone 108 and a second zone 110. The electrical device 103 can be placed into the electrical receptacle box 101 in a step 408. In a step 410, the electrical device 103 can be secured to or within the electrical receptacle box 101. The electrical device 103 can be secured using a fastener such as a screw. The face plate 100 can be coupled or placed onto the electrical device 103 in a step 412, where the electrical device 103 can include a wall mounted electrical device. In a step 414, the face plate 100 can be secured to the electrical device 103 using a fastener such as a screw. Where the face plate is installed, the electrical device 103 has been made safer and more easily identified.

(31) Advantageously, the face plate 100, the electrical device recognition safety system 200, the electrical device recognition safety kit 300, and the method 400 of making a wall mounted electrical device 103 safer and more easily identified described hereinabove can allow the user to easily identify where an electrical outlet 105 or light switch 107 is located on a wall.
