## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of U.S. application Ser. No. 12/641,866, filed Dec. 18, 2009, which claims priority to provisional application Ser. No. 61/139,616 filed on Dec. 21, 2008, each of which is herein incorporated by reference in its entirety.


BACKGROUND
1. Field of the Application
The present application relates generally to a walking aid or other human-powered locomotion and stabilization aid having an illumination source. The walking aid may be used by individuals in recreational activities, as well as by physically challenged individuals engaged in their daily activities. The illuminated walking aid may facilitate moving more safely from one place to another where an individual or group would benefit from seeing the floor, ground, or other surface more clearly, or by being seen more easily by others.
2. Description of the Related Art
Recreational hiking poles and ski poles assist hikers, skiers, skaters, mountain climbers, and search and rescue teams when they need to stabilize themselves and their footing while engaged in such activities. Canes, walkers, crutches, and walking carts similarly provide physically challenged persons and people with physical disabilities with needed stability when moving from one place to another. The value of canes, walkers, hiking poles and similar devices in assisting individuals desiring greater stability correlates directly with how well the ends or tips of the poles, canes, etc. connect with the ground to achieve the desired and required weight-bearing traction and support. When compromised or deficient lighting or visibility conditions exist, whether outside in twilight, at night, or in overcast, rainy or snowy conditions, or when inside where lighting conditions may be poor, it is more difficult to ensure the necessary stable footing from the placement of the walking aid pole or cane base to achieve the required or desired safe traction and load-bearing stability.
These as well as other aspects and advantages will become apparent to those of ordinary skill in the art by reading the following detailed description, with reference where appropriate to the accompanying drawings. Further, it should be understood that the embodiments described in this summary and elsewhere are intended to illustrate the invention by way of example only.

DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
One example embodiment provides an illuminated apparatus for assisting movement, such as a walking aid, which provides light in a generally downward direction toward the feet of a user. The walking aid may be used for recreational pursuits, search and rescue activities, or physically challenged ambulatory movement. The walking aid allows the user to clearly see where their feet, skis, skates, and crampons and the tips of their walking, skiing and skating poles, canes or walkers should be placed so that the necessary load-bearing stability assistance results are achieved when lighting and visibility conditions are less than optimal. The walking aid provides circumferential lighting to illuminate areas in front of, to the sides of, and behind the walking aid, allowing for suitable movement over uneven terrain commonly encountered when hiking, climbing or skiing. The walking aid may also be used as a signaling device or for pointing and illuminating objects in the surrounding vicinity, for example.
The illuminated walking aid provides users with all forms of helpful features exemplified by a streamlined, weatherproof, and waterproof molded enclosure that is impervious to the challenging conditions to which it may be exposed. The illuminated walking aid further includes illumination sources that are adjustable from both directional and lighting intensity perspectives, as well as rechargeable and disposable battery power source flexibility. The streamlined and rugged embodiments are designed to easily shed branches and other obstructions as well as being able to easily stand up to other harsh elements commonly encountered during outdoor activities such as backpacking, hiking, mountaineering, and backcountry skiing.
Turning now to the drawings, FIG. 1 shows an exemplary apparatus for assisting movement, such as a walking aid 100, of the present application. As discussed above, the apparatus for assisting movement may be a hiking pole, ski pole, cane, walker, or other stabilizing or balancing device used to make walking, hiking, climbing, skiing, and similar activities safer and more efficient. The walking aid may include a pole 102 having a first end 104 and a second end 106. The pole 102 may include a generally elongated shaft, which may have a cylindrical or non-cylindrical cross-section. Pole 102 may also be adjustable in length. In one embodiment, the pole 102 may include a handle 200 secured to the first end 104. The handle 200 may be oriented generally along the elongated shaft, in a direction parallel to a longitudinal axis of the generally elongated shaft, and in a generally vertical direction. In an alternate embodiment, the handle 200 may be oriented in a direction perpendicular to the generally elongated shaft. The handle 200 may be molded to the first end 104, or alternatively, may be secured to the top end by any suitable connection mechanism.
Referring to FIG. 2, the handle 200 may include a first end 202 and a second end 204. The first end 202 of the handle 200 may be oriented toward the first end 104 of the pole and the second end 204 of the handle 200 may be oriented toward the second end 106 of the pole 102. The handle 200 may also include a gripping portion 201 which facilitates gripping of the handle by a user. The handle 200 may further include a removable portion 206 at the first end 202. The removable portion 206 may be attached to the first end by a hinge 207, for example. The handle 200 may also include an inner cavity 208, which is best seen in FIGS. 3 and 4, which may accommodate power sources, electronics, and light sources. The removable portion 206 can be closed to seal the inner cavity 208 to protect its contents from the elements. Thus, the handle 200 may be water resistant, and may be constructed of plastic, rubber, or metal, for example. The handle may also include a strap 209 connected to the first end 202 to aid a user in holding onto the handle 200. Alternatively, the strap 209 may be connected anywhere on the handle 200 or pole 102.
The second end 204 of the handle 200 may include at least one light source 210, which may be a light emitting diode (LED), for example. Alternatively, the light source may be any other suitable light source, such as incandescent or fluorescent, for example. In other embodiments, three light sources are included on the handle 200. The light source 210 may be positioned within a light compartment 212 located at the second end 204 of the handle 200 to protect the light source 210. The light source may project generally downwardly toward any surface on which a user might move, such as the ground, floor, or surface upon which a person would walk, hike, climb, or ski.
As shown in FIGS. 3 and 4, the handle 200 may include at least one power source 214 mounted in a power source compartment 216 in an orientation perpendicular relative to the shaft of the handle. In one embodiment, the power source 214 may include three AAA batteries. In another embodiment, the power source 214 may include one or more rechargeable batteries. Alternatively, the power source may be any suitable energy generating device. The removable portion 206 of the handle allows the power source 214 to be easily loaded or recharged to power the illumination of the light source 210. Both positive and negative wires 218, 220 run from contacts 222 located in the power source compartment 216 down through the inner cavity 208 of the handle 200 to the light compartment 212 which contains the light source 210, a circuit board 224, light source lens 226, and a light switch 228. The light source lens 226 may surround the light source 210 and may diffuse or focus the light. One example of a light source lens 226 is shown in FIG. 3.
The light switch 228 may take any form, including a control switch, a toggle, or a thumbwheel, for example. Pressing on the light switch allows the user to toggle the light between different modes for different lighting conditions, including levels for low, medium, and high brightness, as well as a strobe setting, which are all settings that may be integrated into the circuit board 224. Alternatively, the light switch 228 may be mounted near the first end 202 of the handle under the power source compartment 216, or in the removable portion 206, so that a user may operate the switch with one forefinger or thumb while gripping the handle 200.
The handle 200 may alternatively be configured with directionally controllable light sources (not shown). In this configuration, the light source 210, the light source lens 226, the circuit board 224, and the adjacent portion of the enclosure which houses these components may be mounted on a locking pivot (not shown). By loosening the pivot, adjusting the light direction, and re-tightening the pivot, the light source may be tilted forward or backward to better control the area being illuminated in front of or behind the user.
The handle 200 may further include a “power on” power source indicator light located on the light compartment 212. Alternatively, the power source indicator light may be mounted near the first end 202 of the handle under the power source compartment 216, or in the removable portion 206. Further, the handle 200 may include a remaining power indicator gauge located on the light compartment 212 to alert the user of how much power remains in the power source. Alternatively, the remaining power source indicator gauge may be mounted near the first end 202 of the handle under the power source compartment 216, or in the removable portion 206.
In operation, a user turns the light switch, or other such control, into the “power on” position. The user then may select the desired lighting level. The electronics and circuit board within the device regulate the power to the lights based on how the switch has been set. Some embodiments of the light source circumferentially illuminate the floor, ground, or desired surface, and also provide illumination of objects near the pole, including but not limited to the person using the device, to ensure stable footing or placement of skis, skates, crampons, pole and cane tips and ends. Other embodiments may include other forms of lighting, such as a spotlight or floodlight, for example, or noncircumferential lighting.
FIGS. 5-7 show an alternate embodiment of the handle 300 that may be connected to a walking aid, such as pole 102. In this embodiment, the handle 300 has a first end 302 and a second end 304. The first end 302 of the handle 300 may be oriented toward the first end 104 of the pole and the second end 304 of the handle 300 may be oriented toward the second end 106 of the pole 102. The handle 300 may be oriented generally along the elongated shaft of the pole, in a direction parallel to a longitudinal axis of the generally elongated shaft, and in a generally vertical direction. In an alternate embodiment, the handle 300 may be oriented in a direction perpendicular to the generally elongated shaft. The handle 300 may also include a gripping portion 301 which facilitates gripping of the handle by a user. The handle 300 may further include a removable portion 306 at the first end 302.

In one embodiment, the power source 314 may include three AAA batteries. In another embodiment, the power source 314 may include one or more rechargeable batteries. Alternatively, the power source may be any suitable energy generating device. The removable portion 306 of the handle allows the batteries to be easily loaded or recharged to power the illumination of the light source 310. Both positive and negative wires 318, 320 run from contacts 322 located in the inner cavity of the handle 300 to the light compartment 312, which contains the light source 310, a circuit board 324, a light source lenses 326, and a light switch 328. Pressing on the light switch allows the user to toggle the light between different modes for different lighting conditions, including levels for low, medium, and high brightness, as well as a strobe setting, which are all settings that may be integrated into the circuit board 324. Alternatively, the light switch 328 may be mounted near the first end 302 of the handle so that a user may operate the switch with a forefinger or thumb while gripping the handle 300.
The handle 300 may alternatively be configured with directionally controllable light sources. In this configuration, the light source 310, the light source lens 326, the circuit board 324, and the adjacent portion of the enclosure which houses these components may be mounted on a locking pivot (not shown). By loosening the pivot, adjusting the light direction, and re-tightening the pivot, the light source may be tilted forward or backward to better control the area being illuminated in front of or behind the user.
In operation, a user turns the light switch, or other such control, into the “power on” position. The user then may select the desired lighting level. The electronics and circuit board within the device regulate the power to the lights based on how the switch has been set. The light source circumferentially illuminates the floor, ground, or desired surface, and also provides illumination of objects near the pole, including but not limited to the person using the device, to ensure stable footing or placement of skis, skates, crampons, pole and cane tips and ends.
In yet another embodiment shown in FIGS. 8-10, a handle 400 may be mounted to a pole, such as pole 102. The handle 400 may include a first end 402 and a second end 404. The first end 402 of the handle 400 may be oriented toward the first end 104 of the pole and the second end 404 of the handle 400 may be oriented toward the second end 106 of the pole 102. The handle 400 may be oriented generally along the elongated shaft of the pole, in a direction parallel to a longitudinal axis of the generally elongated shaft, and in a generally vertical direction. In an alternate embodiment, the handle 400 may be oriented in a direction perpendicular to the generally elongated shaft. The second end 404 of the handle 400 houses a power source 414, contacts 422, a light source 410, a light source lens 426, a light switch 428 and a circuit board 424. The contacts 422 allow for current to run up one power source, across the contact 422, and back down the adjacent power source 414.
Referring to FIG. 10, the handle 400 may include an internal canister 416 toward the second end 404, which may be cylindrical or any other suitable shape. The canister 416 may be removeably connected to the first end 402 of the handle 400 at portion 406. The canister 416 may be unlocked from its closed position and slid down the pole to provide access for replacing the power source 414. Once the power source 414 has been replaced, the canister 416 may be slid back up the pole and locked back into the handle 400. The canister 416 may be secured to the handle 400 by any suitable fastening mechanism.
The second end 404 of the handle 400 may include at least one light source 410, which may be a light emitting diode (LED). Alternatively, the light source may be any other suitable light source, such as incandescent or fluorescent, for example. In other embodiments, four light sources are included on the handle 400. The light source 410 may project generally downwardly toward the ground, floor, or surface upon which a person would walk, hike, climb, or ski. Pressing on the light switch allows the user to toggle the light between different modes for different lighting conditions, including levels for low, medium, and high brightness, as well as a strobe setting, which are all settings that may be integrated into the circuit board 424. Alternatively, the light switch may be mounted near the first end 402 of the handle so that a user may operate the switch with a forefinger or thumb while gripping the handle 400.
Referring now to FIGS. 11-14, another embodiment of a light source is disclosed. In this embodiment, a detachable light source 500 may be removeably attached to a hiking pole, cane or other walking aid, such as walking aid 100. Thus, the detachable light source 500 may be removed from the walking aid, if desired, and held in the hand of a user and used as a flashlight, hung or placed on a surface to serve as a lantern, or mounted to any other object.
The detachable light source 500 may be secured to the pole 102 of the walking aid 100, preferably near the first end 104 of the walking aid 100. Positioning the detachable light source near the first end 104 reduces the cantilevered weight effect caused by having the device mounted lower on the pole 102 towards end 106. The higher mounting position also reduces the user's fatigue in carrying a light source as extra weight on a hiking pole. Alternatively, the detachable light source 500 may be secured to any area of the pole 102. The detachable light source 500 may also be removed from the pole.
The example detachable light source 500 may include housing 502 configured to accommodate at least one light source 504. The at least one light source 504 may be a light emitting diode (LED). Alternatively, the light source 504 may be any other suitable light source, such as incandescent or fluorescent, for example. The housing 502 may further comprise a clam shell closure or other clamping mechanism 506 which allows the detachable light source 500 to be attached to poles of varying diameters or having non-symmetrical cross sections. In one example, the clamping mechanism 506 may be removeably connected to the housing 502 so the detachable light source 500 may be removed from the clamping mechanism. Alternatively, the clamping mechanism 506 may be molded directly into the housing 502.
The clamping mechanism 506 may include a first portion 511 and a second portion 512. The clamping mechanism may further include an adjustment knob 508 having an outwardly extending member 510 connected to the first portion 511. The knob 508 may be turned either clockwise or counterclockwise to tighten or loosen the detachable light source 500 from the pole 102. The second portion 512 may include an aperture 514 for accommodating the outwardly extending member 510 of the knob 508. Soft gripping surfaces 509 may be mounted to the inside surfaces of the first and second portions 511, 512 to ensure that the light source 500 stays in place on the pole 100.
The sealed housing 502 may protect all of the illuminator's components, including power sources and electronics. As shown in FIG. 14, the housing 502 may include at least one power source 516 mounted inside of the housing 502. The housing 502 may further include a removable portion 501 that may snap on and off of the detachable light source 500 for replacement of the power source 516. The removable portion 501 may be attached to the first end by a hinge, strap, or other suitable means (not shown), for example. The power source 516 may be positioned parallel to the shaft of the pole 102. In one embodiment, the power source 516 may include four AAA batteries. In another embodiment, the power source 516 may include one or more rechargeable batteries. Alternatively, the power source may be any suitable energy generating device. The housing 502 may be designed to be separable from the clamping mechanism 506 which holds the entire device securely onto the pole 102.
At least one power source contact 518 may be mounted to the removable portion 501, thereby allowing electrical current to be passed up one power source and down the next without the need for separate wiring to be run from the top of the device down to a circuit board 520. Physical wires (not shown) may run from the at least one power source contact 518 to the circuit board 520. All remaining wiring takes place in the form of a circuit built into the circuit board 520 itself.
The at least one light source 504 may be mounted directly to the circuit board 520, and when illuminated, light passes from the light source 504 through its associated lens 522. The detachable light source 500 may further include a light switch 524, which may be mounted anywhere on the housing 502. Pressing on the light switch 524 allows the user to toggle the light source 504 between different modes for different lighting conditions, including levels for low, medium, and high brightness, as well as a strobe setting, as described above.
In operation, the detachable light source 500 may be secured to the pole 102 by removing the outwardly extending member 510 from the aperture 514 in the back plate 512. The housing may then be positioned around the pole 102, and the outwardly extending member 510 may be placed back within the aperture 514 in the back plate 512. The knob 508 may then be turned to tighten the detachable light source 500 securely onto the pole 102. The soft gripping surfaces 509 ensure that the detachable light source 500 remains in place on pole 100. The detachable light source 500 may be mounted onto the pole 102 so that the light source 504 points in a generally downward direction toward the floor or ground. Alternatively, the detachable light source 500 may be mounted onto the pole 102 so that the light source 504 points in any direction, if desired.
In yet another embodiment of a detachable light source shown in FIGS. 15-17, a detachable light source 600 may include a directionally controlled light source. The detachable light source 600 may be attached to a hiking pole, cane or other walking aid, such as walking aid 100. The detachable light source 600 may be secured to the pole 102 of the walking aid 100, preferably near the first end 104 of the walking aid 100. Alternatively, the detachable light source 600 may be secured to any area of the pole 102.
The example detachable light source 600 may include a housing 602 configured to accommodate at least one light source 604. The at least one light source 604 may be a light emitting diode (LED). Alternatively, the light source 604 may be any other suitable light source, such as incandescent or fluorescent, for example. The housing 602 may further comprise a clam shell closure or other clamping mechanism 606 similar to the clamping mechanism 506 described above with respect to the detachable light source 500. The clamping mechanism 606 of the detachable light source 600 may include a first portion 608 and a second portion 609. The first portion 608 may include an outwardly extending arm 610. The outwardly extending arm 610 may be secured to a corresponding extending arm 612 of the housing 602. The internal electronics for this embodiment are substantially the same as described above with respect to the detachable light source 500.
In operation, a user may adjust the angle and direction of the light source 600 by unlocking the knob 614. The detachable light 600 may then be tilted either forwards or backwards to provide for lighting further in front of the user, or to provide light to someone who is walking, hiking, skiing, etc behind the user. When the desired position of the light is obtained, the user may lock the detachable light source 600 in place by tightening the knob 614. The detachable light source 600 may be secured to the pole 102 in the same manner as described above with respect to detachable light source 500.
Referring now to FIG. 18, another embodiment of an apparatus for assisting movement or walking aid 700 is shown. As discussed above, the apparatus for assisting movement 700 may be a cane, a walker, a hiking or ski pole, or any other stabilizing or balancing device. The walking aid 700 may have a generally elongated shaft 702. The generally elongated shaft 702 may have a first end 704 and a second end 706. The first end 704 may include a handle 708. As shown in FIG. 18, the handle 708 may be oriented substantially parallel to the walking surface. In an alternate embodiment, the handle 708 may be oriented substantially perpendicular to the walking surface. Other possibilities exist as well. The handle 708 may be similar to the handle 200 described above. Thus, in some embodiments, the handle 708 may include a gripping portion, a removable portion, and an inner cavity.
The second end 706 is in contact with the walking surface. Although the second end 706 is shown to have one leg, it should be understood that the second end may include any number of legs in contact with the walking surface to provide additional stability.
The shaft 702 may also include a generally longitudinal portion 710 extending upwardly from the second end 706. A housing 712 containing at least one light source 713 (shown in FIGS. 19 and 21) may be oriented around the generally longitudinal portion 710 of the shaft 702. The housing 712 may be permanently or removeably mounted to the shaft 702. In one embodiment, the housing 712 may be mounted to the shaft 702 by a fastening mechanism 715 (shown in FIG. 21), such as by a plurality of screws, for example. Alternatively, any suitable fastening mechanism may secure the housing 712 to the shaft 702.
The light source 713 may comprise an LED, for example. Alternatively, the light source 713 may be any other suitable light source, such as incandescent or fluorescent, for example. In one embodiment, a plurality of light sources may be positioned around the generally longitudinal portion 710 of the shaft.

In another embodiment, the light source 713 or plurality of light sources may each project at any angle from 0-90 degrees from the walking surface.
The shaft 702 may further include an offset portion or bend 703 located between the handle 708 and the generally longitudinal portion 710. The offset portion 703 may include a curved portion, for example, or may take any suitable shape. The offset portion 703 centers the line of force through the shaft 702 to the second end 706, thereby providing more stability to the user. The offset portion 703 further provides comfort and support to the user. Alternatively, the housing 712 and light source 713 may be mounted to the apparatus for assisting movement 100 described above.
The shaft 702 may further include at least one power source 714 mounted within the shaft 702 toward the second end 706 of the shaft, as shown in FIGS. 19 and 20. Alternatively, the power source 714 may be located in the handle 708, in housing 712, or anywhere else along the shaft 702. In one embodiment, the power source 714 may include four AAA batteries. In another embodiment, the power source 714 may include one or more rechargeable batteries. Alternatively, the power source may be any suitable energy generating device. In one example, the second end 706 of the shaft 702 may include a removable portion 716 that allows the power source 714 to be easily loaded into power the illumination of the light source 713.
In one example embodiment, the apparatus 700 may include a low battery indicator for alerting a user that battery function is declining. For example, when the batteries start to become low on power, a light or other indicator may begin to flash slowly, letting the user know that he or she should start considering the replacement of the batteries. As the batteries are just about to lose all power, the light may start to flash more quickly, indicating that a complete end of life for the batteries is about to occur. In another example, the indicator may be a sound or alarm. The low battery indicator may be located anywhere on the shaft 702 or the handle 708 of the apparatus 700. The low battery indicator may also be used with any of the embodiments described above with respect to FIGS. 1-17.
One or more wires 718 run from a circuit board 720 located in the housing 712 down through the shaft 702 to the power source 714. A circuit board 720 and a light switch (not shown) are also located in the housing 712. The circuit board and light switch may alternatively be located near the power source 714. The light switch may take any form, including a control switch, a toggle, or a thumbwheel, for example, as described above.
In operation, a user turns the light switch, or other such control, into the “power on” position. The user then may select the desired lighting level. The electronics and circuit board within the device regulate the power to the lights based on how the switch has been set.
In another embodiment, the light source 713 may include motion and/or photo sensing (day or night) functionality. For example, once the light source 713 has been turned on, the light may sense if any motion is occurring in the apparatus 700. If motion is sensed, the system then automatically checks to see whether a less than desirable amount of light exists within the surrounding area. If the system determines a less than adequate lighting situation exists, the light source will automatically turn on. If sufficient light exists in the surrounding area, the light source will not turn on even if it has sensed motion (i.e.—someone has touched or picked up their cane). The light source will remain on as long as it continues to sense motion and insufficient light. Once motion has completely stopped for an adequate period of time (such as for one minute, for example), the light source will turn off. Thus, a user may turn on the light switch one time between changes of batteries.
The light source 713 circumferentially illuminates the floor, ground, or desired surface, and also provides illumination of objects near the pole, including but not limited to the person using the device, to ensure stable footing or placement of skis, skates, crampons, pole and cane tips and ends. Although certain aspects show the light source providing circumferential illumination, other embodiments may include other forms of lighting, such as a spotlight or floodlight, for example, or noncircumferential lighting.
FIGS. 22-23 show an alternative embodiment of a housing 800 for attachment to the shaft 702 of walking aid 700. The housing 800 includes one or more chambers or compartments 802 for encasing a light source, such as light source 713 described above. The housing 800 may be positioned anywhere on the shaft 702 so that the light source projects generally downwardly toward the walking surface.
As shown in FIG. 23, a power source 806 is mounted within the shaft 702 toward the second end 706 of the shaft. Alternatively, the power source 806 may be located in the handle 708 or anywhere else along the shaft 702. The power source 806 may comprise any of the power sources mentioned above with respect to FIG. 20. Further, a circuit board 808 and a light switch 810 may also be located toward the second end 706 of the shaft near the power source 806. The circuit board 808 and light switch 810 may alternatively be located in the housing 800. The light switch 810 may take any form, including a control switch, a toggle, or a thumbwheel, for example, as described above.
In another embodiment, shown in FIGS. 24-27, a housing 900 containing at least one light source 904 may be detachably connected to the shaft 702. The housing 900 may be positioned on either the offset portion 703 or the generally longitudinal portion 710 of the shaft 702. The housing 900 may also include a removable portion 902 for replacement of a power source 906. The removeable portion 902 may be attached to the housing 900 by a hinge, for example.
The housing 900 may be attached to the shaft 702 by a fastening mechanism 908, which may be one or more screws, for example. Alternatively, any other suitable fastening mechanism may be used to secure the housing 900 to the shaft 702. One or more plugs 910 may cover holes used to insert a portion of the fastening mechanism. The housing 900 may further include a light switch 912 for controlling the light source 904. The light switch 912 may take any form, including a control switch, a toggle, or a thumbwheel, for example, as described above. Alternatively or additionally, the light source 904 may include motion and ambient light sensing (day or night) functionality.
Referring to FIG. 27, the light sources 904 are positioned within the housing 900 in such a way that the light rays 905 extend 360° around the shaft 702. In one example, the light sources 904 may be positioned around the shaft 702 in a generally arcuate or curvilinear manner. In one embodiment, four light sources 904 may be located within the housing 900, with the outer light sources being positioned between approximately 0° and about 26° above a central horizontal axis 906 of the shaft 702, and on a radius approximately equal to the diameter of the shaft 702. Positioning the light sources in such a manner provides for full circumferential lighting, though the light sources themselves may not completely surround shaft 702. Further, in one example, the light sources 904 may include an LED having a brightness of 35,000 millicandelas. Other possibilities exist as well.
It should be understood that any of the features described above with respect to the embodiments shown in FIGS. 18-27 may also be used in combination with any of the features or embodiments shown in FIGS. 1-17.
Additional features of the present invention include, but are not limited to, convenience, ease of use, ergonomics, sturdiness, reliability, portability and efficiency.
