[0002] This application is related to the field of lighting and more particularly a system for providing uniform light distribution from a plurality' of light sources.RELATED APPLICATIONS
[0003] This application is related to the USP7,682,042; USP 8.851.709; RE 46463; USP 9,791,138; USP10, 240,769; USP 10, 247,384; USP 10,527,254, 11,060,695; 11, 231, 165;11, 099, 376; 11,608, 961 and 11, 719, 925 and those patent applications that claim priority7therefrom, the contents of all of which, which are assigned to the Assignee of the instant invention, are incorporated by reference, herein.BACKGROUND OF THE INVENTION
[0004] Lighting elements are typically used in dental, medical and / or surgical fields to allow practitioners (e.g., dentist, doctor, surgeons, etc.) to apply light directly to the area where the practitioner is viewing. Some lighting elements may be free-standing lamps that a practitioner may position about the work area. Other lighting elements may be overhead lighting elements that operate on an arm that the practitioner may position about the work area. User-wearable (e.g., head-mounted) lighting elements may also be used by a practitioner to provide a tight light beam directly coincident with the practitioner’s line of sight. Head-mounted lighting elements are advantageous as the projected light is directly at the focus of the practitioner’s eyes and the practitioner’s shadow is not projected onto the work area as in the case of overhead lights.
[0005] Operation of such head-mounted elements is known in the art. For example, USP 8,851,709; RE46463; USP 9,791,138; USP 10,240,769; and USP 10,527, 254, which are assigned to the Assignee of the instant application, disclose user-wearable (e.g., headSerial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light OutputAttn. Dock. No.: DVI-105PCTAttn.: CarlA. Giordano, Reg. No.: 41780 November 2024 mounted) elements and their operation. Similarly, USP 7,682,042, which is assigned to the Assignee of the instant application, discloses an overhead or lamp configuration. The contents of all of which are incorporated by reference, herein.
[0006] Typically, with a head mounted lighting element, a practitioner (e.g., a dentist, a doctor, a surgeon) adjusts the lighting element such that the light is projected onto a surface to which the practitioner’s eyes are focused. The practitioner may then control the light output in a manner as disclosed in the aforementioned US patents.
[0007] In addition to projecting a light (such as a white light) for assisting the practitioner in viewing the targeted area, the lighting element may be composed of different lighting sources that may be used for different purposes. For example, the light sources may generate an ultraviolet light (non-visible wavelength range), a visible light (e.g., white, red, green, blue, etc.) or an Infra-red (IR) (non-visible wavelength), wherein the specific wavelength band may achieve a desired purpose. For example, some light wavelengths are known to decrease the time of gel-like materials to harden. In addition, the lighting elements may comprise one or more of the different light sources may be generating a corresponding light concurrently; the control of which may require wired or wireless control circuitry.
[0008] However, user-wearable elements are required to be compact and lightweight, which limits the number of light emitting elements that may be used in emitting a light. The limited number of lighting emitting elements within the head-mounted lighting elements limits the overall intensity7of the light emitted by the head-mounted lighting element at a desired working distance.
[0009] Lighting elements with multiple lighting sources are disclosed in US patents 9,781,138; 11, 231, 165; 11, 099, 376, and 11, 719, 925, for example, whose contents, as previously discussed, are incorporated by reference. How ever, such elements operate to produce a light output with a broad light beam that is substantially uniformly distributed over a wide area. The intensity of the light emitted being limited by the positioning of the lighting sources.
[0010] Hence, there is a need in the industry for a system that allows for a greater emission distribution of light from lighting elements, particularly of the user-w earable kind, w herein the distribution of the emitted light is concentrated onto a desired area.SUMMARY OF THE INVENTIONSerial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light OutputAttn.

As would be recognized the position of reflective surfaces with respect to lighting sources 412 alters the region 515 on lens assembly 120 and accordingly, the required performance of obj ective lens 502, 504 in converging the emitted light onto a region surrounding common point 330.Serial no.: TBD Filing Date: TBD For: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCT Attn.: CarlA. Giordano, Reg. No.: 41780 November 2024
[0078] In accordance with the principles of the invention, the lighting elements illustrated in FIGs. 5A-5H, containing therein at least one lighting source 412 may be configured to emit light in one or more light wavelength ranges. For example, lighting elements shown in FIGs. 5A-5H may emit light in one or more of a non-visible wavelength range (e.g., infra-red, ultraviolet) or selected wavelength bands associated with visible light (e.g., blue light 400-450 nanometers (nm), green light 500-560 nm, red light 700-780nm, etc.) or within a white wavelength band (i.e., 400-780 nm) .
[0079] In still a further aspect of the invention, an excitation filter (not shown) may be incorporated into a proximal end of lens assembly 120, wherein excitation filter is configured to limit a wavelength range of a light emitted by lighting sources 412. In one aspect of the invention, the optical characteristics of excitation filter (not shown) may be selected based on an expected wavelength range of light emitted by lighting sources 412. Alternatively, the optical characteristics of excitation filter (not shown)may be selected to limit the output of light assembly 500 etc., to a desired wavelength range.
[0080] Although, lighting sources 412 has been shown to be positioned substantially perpendicular (i.e., within known engineering tolerances) to housing 110, it would be recognized by those skilled in the art that lighting sources 412 may be positioned at a different angle (i.e., an offset angle), by the proper adjustment or orientation of a corresponding light director within housing 110. Hence, while discussion has been made with regard to a substantially perpendicular orientation, or offset, of lighting source 412 with respect to housing 110. it would be understood that the orientation of lighting source 412 with regard to housing 110 may be altered without altering the scope of the invention claimed.
[0081] Although two independent reflective surfaces are shown, it would be recognized that more than two reflective surfaces may comprise light director (or prismatic structure) 591, wherein the reflective surfaces arranged at an apex angle that may be at an obtuse angle (greater 90 degrees), a right angle (90 degrees) or an acute angle (less than 90 degrees).
[0082] FIG. 6A illustrates a perspective view of an exemplar}' light distribution associated with the lighting configuration shown in FIGs. 5A-5H.
[0083] In this illustrated example of light distribution, it w ould be recognized that the light emitted by lighting sources 412 and re-directed by corresponding surfaces 512, 514 extend parallel to optical axis (not shown), such that two distinct light regions or spots 612, 614 areSerial no.: TBD Filing Date: TBD For: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCT Attn.: CarlA. Giordano, Reg. No.: 41780 November 2024 formed. Each of light regions or spots 612, 614 possess an intensity or brightness associated with the corresponding lighting source 412.
[0084] FIG. 6B illustrates a perspective view of an exemplary light distribution associated with the lighting configuration shown in FIGs. 5A-5F in accordance with the principles of the invention.
[0085] In this illustrated example of light distribution, the introduction of objective lens 130 into the light paths associated with the light redirected from reflective surfaces 512, 514 are “bent” by the characteristics of lens 130 such that the light converges into a single light region or area substantially surrounding common point 330 a desired distance from objective lens 130.
[0086] A determination of the apex angle of the light directors shown herein may consider at least one of:
[0087] Index of refraction of the material of the lens (i.e., optical characteristics);
[0088] a radius (power) of the lenses that the light emitted by the lights sources passes through;
[0089] a location of where the light passes through the lenses with respect to an optical axis of the lenses (i.e., optical characteristics);
[0090] an index of refraction of lenses:
[0091] a distance of the lenses with respect to the light director; and
[0092] a focal lengths of the desired distance to focus the light.
[0093] FIG. 7A illustrates a first chart for determination of lens system power to achieve a desired level of light intensity at common point or convergence point 330.
[0094] In this illustrated chart, the exemplary embodiment of a lighting assembly similar to that shown in FIG. 5G is constructed, wherein a distance to common point 330 is to 16 inches. In this illustrated exemplary embodiment, the apex angle 562 between reflective surfaces 512, 514 (FIG. 6B) is varied as the lens power of lens system 130 is held steady. A measure of the degree of convergence of the light emitted by light sources 412 at the common or convergence point 330 is obtained so as to obtain a desired (e.g., a maximum) light intensity.Serial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCTAttn.: CarlA. Giordano, Reg. No.: 41780 November 2024
[0095] As shown in FIG. 7A, with an apex angle of substantially 90 degrees (i.e., within manufacturing tolerances), convergence of the light emitted by light sources 412 is not achievable with objective lens 130 of less than 24.0 diopters.
[0096] However, with an angle less than 90 degrees convergence of the light emitted by light sources 412 may be achieved. For example, at 77 degrees with an objective lens 130 having a power of +8.00 diopters (i.e., 2x power) , convergence of light is approximately 100 per cent, and at 75 degrees with lens power of +16.00 diopters (i.e., 4x power) convergence is approximately 90 percent. Accordingly, the light beams associated with the light emitted by lighting sources 412 essentially completely overlap or focused at the desired distance of 16 inches with the appropriate selection of lens power and apex angle.
[0097] FIG. 7B illustrates a second chart for determination of lens system power to achieve a desired level of light intensity at common point or convergence point.
[0098] In this illustrated chart, the exemplary embodiment of a lighting assembly similar to that shown in FIG. 5G is constructed and common point 330 is measured at approximately 20 inches from lens assembly 120. In this illustrated example, convergence of light emitted by lighting sources 412 is achieved with an apex angle of 75 degrees with +16.00 diopter lens assembly power.
[0099] Accordingly, the light beams associated with the light emitted by lighting sources 412 essentially completely overlap at (or focused at) the desired distance of 20 inches with the appropriate selection of lens power and apex angle.
[0100] Although measurements have been taken utilizing only a single lighting configuration (i.e.. FIG. 5G) and at two (2) distances (16 and 20 inches) with three (3) objective lens powers, it would be recognized that the method disclosed, herein, for determining an apex angle that achieves substantially 100 per cent convergence (i.e., nearly completely overlap) of the beams of light emitted by separate lighting sources 412 would be applicable to different combinations of lighting configurations, without altering the scope of the invention.
[0101] Although light convergence is discussed in the context of determining a desired configuration, it would be recognized that the determination of light intensity at a desired distance may also be a criteria for the selection of factors such as lens power and apex angle. In addition, those skilled in the art would further recognize that the size of theSerial no.: TBD Filing Date: TBD For: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCT Attn.: CarlA. Giordano, Reg. No.: 41780 November 2024 convergence of the emitted light may also be considered. In this case, the beamwidth of the lighting sources 412 may further be a variable to be taken into consideration.
[0102] FIGs. 8A and 8B illustrate still further exemplary embodiments of the lighting assembly in accordance with the principles of the invention.
[0103] FIG. 8 A illustrates a configuration 800 similar to that shown in FIG. 5 A, wherein an objective lens configuration 502, 504 is associated with each of lighting sources 412. In this exemplary embodiment, the light emitted by lighting sources 412 is focused into a narrower light beam by the inclusion of an object lens configuration 502, 504 positioned within the light path 523, 524 of the light sources 412 prior to being reflected by corresponding reflective surfaces 514, 512. In this illustrated embodiment, lens assembly 120 comprises a piano lens 830 as the light emitted by lighting sources 412 is more focused onto reflective surfaces 512, 514. Although lens 830 is shown, it would be recognized that lens assembly 120 may comprise objective lens 130 as discussed and shown previously.
[0104] FIG. 8B illustrates a configuration 810 similar to that shown in FIG. 8 A, wherein filter elements 815 are incorporated into the light path between the plurality of lighting sources 412 and a corresponding one of the reflective surfaces. Filter elements 815 may be formulated to pass selected wavelengths of light emitted by lighting sources 412 to be the same or different. In one example, lighting sources 412 may emit a white light and filters 815 may be formulated to limit the light contacting a corresponding reflective surfaces to be within a specific wavelength range (e.g., , between 500-600 nanometers). In still another aspect, filters 815 may be associated with selected ones of the plurality of lighting sources 412, such that the light emitted by the selected ones of the plurality of lighting sources 412 is filtered and the light emitted by the remaining ones of the plurality of lighting sources may be unfiltered.
[0105] While discussion is made of lighting sources 412 emitting a white light, it would be recognized that lighting sources 412 may emit light in a non-white (i.e., colored light) range which is wavelength limited by corresponding filter 815.
[0106] Further illustrated is filter 826 may be positioned on a distal end of the lighting element 810, wherein filter 826 is configured to limit the wavelength range of the light emitted by lighting sources 412. As would be recognized that filter 826 may be applicable to each of the lighting elements discussed, herein. .Serial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light Output Attn.

[0107] FIG. 8C illustrates a further exemplary embodiment of a lighting element 820, which is similar to the embodiments shown in FIGs. 8 A and 8B, wherein wedge prisms 802, 804 are incorporated into the path of light redirected by lighting director 510. Wedge prisms 802, 804 provide for the divergence of the light emitted by lighting sources 412, such that the region 515 on objective lens 130 is increased. As would be understood from the disclosure presented, herein, the power of objective lens 130 may be adjusted and / or determined using the method described, herein.
[0108] In addition, a second set of lighting sources 412 is incorporated into the lighting assembly 820, wherein the second set of lighting sources 412 is positioned to direct light onto a different region of reflective surfaces 512, 514.
[0109] Although the second set of lighting sources 412 is discussed with regard to the embodiment shown in FIG. 8C, it would be recognized by those skilled in the art that a second set of lighting sources 412 may be incorporated into the exemplary embodiments of the lighting element shown, herein, without altering the scope of the invention claimed.
[0110] FIG. 9 illustrates an exemplary embodiment of an implementation of the telescopic loupe with integrated lighting system in accordance with an aspect of the invention.
[0111] In this illustrated embodiment, system 900 comprises an eyewear 910 comprising frame 915 and right temple 914a and left temple 914b. Frame 915 comprises a right carrier lens 920a and a left carrier lens 920b connected by a bridge element as is known in the art. Incorporated into each of right and left carrier lenses 920b, 920b is telescopic loupe 930a. 930b, respectively. (930a not shown) providing a known level of magnification of an object (not shown) being viewed.
[0112] Although the illustrated embodiment is shown illustrates a Galilean type loupe element (i.e., positive objective, negative eye-lens), it would be understood and recognized by those skilled in the art that that principles of the invention shown, herein, are also applicable to a Keplerian type (positive objective, positive eye-lens) telescopic configuration. Accordingly, the present invention should be considered applicable to both Galilean and Keplerian ty pe loupes.
[0113] Further illustrated is light assembly 950 comprising the lighting assemblies discussed herein (FIGs. 5A-5H and 8A-8C) are incorporated into light assembly 950.Serial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCTAttn.: CarlA. Giordano, Reg. No.: 41780 November 2024
[0114] In one aspect of the invention, the lighting sources 412 within light assembly 950 may be selected to emit light in one or more wavelength ranges. For example, lighting sources 412 may be selected to emit light in a white wavelength band (i.e., 400-700 nm). Alternatively, selected ones of lighting sources 412 may emit light in a white wavelength range (400-700 nm), while selected other ones of lighting sources 412 may emit light in an infra-red wavelength band (i.e., greater than 700nm) or a ultra-violet wavelength range (i.e., less than 500 nm) or in a colored wavelength range (e g., blue 480-520, etc ).
[0115] Although light assembly 950 is discussed and illustrated with regard to a single lighting element, in accordance with the principles of the invention, it would be recognized that lighting elements disclosed may be incorporated into the multiple headlight configurations show n in FIGs. 2 and 3 as lighting assembly 950 illustrated. In these multiple head light configurations, the light emitted from one lighting elements, for example, and light from a second lighting element, may be emitted separately or concurrently. In another aspect, a first lighting element may emit light in a first wavelength band (i.e., 400-500 nm) while a second lighting element may emit light in a second wavelength band (i.e., 450-550 nm). In still another aspect of the invention, light emitted from a first lighting element may be reduced in amplitude (or intensity) when light from a second lighting element is emitted.
[0116] In still another aspect of the invention, one lighting element may emit light in a white wavelength band (i.e., 400-700 nm), whereas a second lighting element may emit light at a first w avelength and a third lighting element may emit light at a second wavelength. The first and second wavelengths may be within a same wavelength band (e.g.. blue) or in a different wavelength band, which may be in the visible wavelength range or in a non-visible wavelength range. For example, the first wavelength may be in a blue wavelength range and the second w avelength may be in an ultraviolet or infra-red wavelength range. The light from lighting elements 500, for example, may be emitted concurrently or separately.
[0117] Although the lighting sources 412 are shown positioned directly onto the inner circumference of the housing 110, it w ould be recognized that the lighting sources 412 may be positioned on a sleeve (not shown) that may be positioned within housing 110. In addition, the light director 510 (for example) may also be positioned within the sleeve and positioned substantially adjacent (i.e., near) the base of housing 110.Serial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light OutputAttn.

[0118] Although the lens assemblies 120 shown in FIGs. 5A-5C , 5E-5H and 8B illustrate dual-biconvex lens and the configuration shown in FIG. 5D illustrates a biconvex and convex / plano lens configuration, it would be recognized by those skilled in the art that objective lens 130 may comprise one or more lenses that may include combinations of convex, concave and piano lenses, individually or in combination, without altering the scope of the invention claimed.
[0119] In summary, a lighting element is presented that allows for the projection of an increased intensity of light onto an object at a known distance from the lighting system.
[0120] In accordance with the principles of the invention, a lighting element 100 (or the lighting elements disclosed, herein) may be incorporated into a lighting element that provides light at greater light intensity' at a same wavelength or at one or more different wavelengths or in one or more different wavelengths bands, wherein the emitted light is directed toward or focus onto a common point such that the common point is of a higher intensity.
[0121] In one aspect of the invention, a single light element may contain lighting elements disclosed herein, wherein the single light element is suspended from an eyewear, a headband or a head-strap and emits light of a greater intensity in one or more wavelength bands. For example, the lighting element may emit light concurrently or separately emit light in a non-visible (i.e. , ultra-violet, infra-red) wavelength range and in a visible wavelength range (e.g., white or non-white (e.g., blue, green, etc.), wherein the emitted light is directed toward a common point such that the light at the common point is of a higher intensity.
[0122] In one aspect of the invention, the lighting elements disclosed herein may be incorporated into a dual lighting assembly7, wherein the lighting assembly7is suspended from an eyewear, a headband or a head-strap and emits light of a greater intensity7in one or more wavelength bands.
[0123] For example, one lighting element of the dual lighting assembly may emit light in a first wavelength band (e.g., non-visible) and the second lighting element may emit light is a visible wavelength band (e.g., white, non-white) toward a common point such that the light at the common point is of a higher intensity'. Alternatively, each of the lighting elements within the dual lighting element may light in both a visible and a non-visible wavelength band toward a common point such that the light at the common point is of aSerial no.: TBD Filing Date: TBD For: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCT Attn.: CarlA. Giordano, Reg. No.: 41780 November 2024 higher intensity. The light emitted by each of the lighting elements may be emitted concurrently or separately in one or more of anon-visible wavelength range or a visible wavelength range. In addition, the intensity of the light emitted by each lighting source within a corresponding lighting element may be varied during the emission of light.
[0124] In still another aspect of the invention, the lighting elements disclosed herein may be incorporated into a triple (or plurality of) lighting assembly, wherein the lighting assembly is suspended from an eyewear, a headband or a head-strap and emits light of a greater intensity in one or more wavelength bands.
[0125] For example, one lighting element of the triple lighting assembly may emit light in at a first wavelength in first wavelength band (e.g., non-visible), a second lighting element may emit light is a visible w avelength band (e.g., white, non-white) and a third lighting element may emit light at a second wavelength within the first wavelength band, wherein the light from each of the lighting elements is directed toward a common point such that the light at the common point is of a higher intensity. Alternatively, each of the lighting elements within the triple lighting assembly may light in both a visible and a non-visible wavelength band tow ard a common point such that the light at the common point is of a higher intensity. The light emitted by each of the lighting elements may be emitted concurrently or separately in one or more of anon-visible wavelength range or a visible wavelength range. In addition, the intensity of the light emitted by each lighting source within a corresponding lighting element may be varied during the emission of light.
[0126] In still another embodiment of the invention, a visualization system may be formulated from the combination of an eyewear with the previously discussed lighting assemblies, wherein the lighting assemblies may be suspended from the eyewear, a headband or a head-strap. The lighting assembly (comprising single, dual or triple lighting elements) may emit light in one or more wavelength bands and the eyew-ear which includes carrier lens may include a filter system, either within the carrier lens or external to the carrier lens, wherein the filter system may cause the attenuation of light viewed by a user in a selected wavelength band while allowing light in another wavelength band to pass substantially unattenuated (i.e., almost zero attenuation.
[0127] In a still further embodiment of the invention, a visualization system may be formulated from the combination of an eyewear with the previously discussed lightingSerial no.: TBD Filing Date: TBD For: Multiple Light Source Configuration with Focused Light Output Attn. Dock. No.: DVI-105PCT Attn.: CarlA. Giordano, Reg. No.: 41780 November 2024 elements, wherein the lighting assembly may be suspended from the eyewear, a headband or ahead-strap. The lighting assembly (comprising single, dual or triple lighting elements) may emit light in one or more wavelength bands and the eyewear which includes carrier lens may include a filter system, either within the carrier lens or external to the carrier lens, wherein the filter system may cause the attenuation of light viewed by a user in a selected wavelength band while allowing light in another wavelength band to pass substantially unattenuated (i.e., almost zero attenuation of the light). In addition, a magnification element may be incorporated into each of the carrier lens, wherein the magnification elements provide for an enlarged view of an area around the common point about which the emitted light is directed toward or focused onto .
[0128] In one aspect of the invention, the magnification elements may include a filtering system wherein the filtering system may cause the attenuation of light viewed by a user in a selected wavelength band while allowing light in another wavelength band to pass substantially unattenuated (i.e., almost zero attenuation). In one aspect the filtering system may comprise a first filter configured to filter light entering the magnification elements such that the light in a first wavelength band may be reduced in magnitude or intensity while allowing light in a second wavelength to pass substantially unattenuated (i.e.. almost 100 percent of the light passes). The filtering capability of the first filter may be determined based on the intensity or magnitude of the incoming light. The filtering system further comprising a second filter, having optical properties to filter the light passing through the magnification element (and been magnified), based on the magnification level of the magnification elements and the optical properties of the first filter. The second filter configured to further reduce in magnitude the light in the first wavelength range while allowing light in a second wavelength range to pass substantially unattenuated.
[0129] Furthermore, the light emitted or output by the light emitting diode(s) is referred to being within a frequency or wavelength range, wherein the wavelength range represents a color (e.g., blue light approximately 400 nanometers to 450 nanometers) . However, it would be further understood that light, particularly with regard to light emitting diodes, may be further measured in color temperature, as degrees Kelvin. For example, a soft white light may be measured in a range of 2700° K -30000K whereas a bright white light may be expressed in a range of 5000° K - 6000 ° K.Serial no.: TBDFiling Date: TBDFor: Multiple Light Source Configuration with Focused Light Output Attn.

[0130] Hence, one of ordinary skill in the art would appreciate that the reference to light or emitted light may be measured as frequency, wavelength, color or color temperature, and such terminology of light is incorporated and used interchangeably, herein.
[0131] One of ordinary skill in the art. however, appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims. Accordingly, the specification is to be regarded in an illustrative manner, rather than with a restrictive view, and all such modifications are intended to be included within the scope of the invention.
[0132] As used herein, the terms "comprises", "comprising", "includes", "including", "has", "having", or any other variation thereof, are intended to cover non-exclusive inclusions. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. In addition, unless expressly stated to the contrary, the term "of refers to an inclusive "or" and not to an exclusive "or". For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present); A is false (or not present) and B is true (or present); and both A and B are true (or present).
[0133] The terms "a" or "an" as used herein are to describe elements and components of the invention. This is done for convenience to the reader and to provide a general sense of the invention. The use of these terms in the description, herein, should be read and understood to include one or at least one. In addition, the singular also includes the plural unless indicated to the contrary. For example, reference to a composition containing "a compound" includes one or more compounds. As used in this specification and the appended claims, the term "or" is generally employed in its sense including "and / or" unless the content clearly dictates otherwise.
[0134] All numeric values are herein assumed to be modified by the term "about." whether or not explicitly indicated. The term "about" generally refers to a range of numbers that one skill in the art would consider equivalent to the recited value (i.e., having the same function or result).

[0135] Although the terms “perpendicular” and “orthogonal” are used herein to describe a relationship between two elements, it would be understood and recognized by those skilled in the art that the terms “perpendicular” and “orthogonal” are not used in the mathematical sense (i.e.. precisely ninety (90) degrees), but rather are used in the manufacturing sense wherein a tolerance value is imposed. Such tolerance values may be considered, for example, + / - 1 degree. Thus, the terms “substantially perpendicular, “substantially “orthogonal.” etc. should be understood as being used to represent a relationship between elements in the manufacturing sense (i.e., within known tolerance values). Similarly, the term “substantially centered,” would be understood to not represent an exact relationship (i.e., a mathematical center) but rather would represent a positioning that is within ty pical or conventional manufacturing tolerances for the placing of one object with respect to another.
