     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new walking aid with suplimental features embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
     As best illustrated in FIGS. 1 through 4, the walking aid  10  with supplimental features  10  generally takes the form of a cane or walking staff with a shaft  20  connecting a gripping tip  24  end and a handle  22  end. The handle end including a hand grip  26 . 
     The material used to construct the walking aid  10  may include metal, plastic or wood, and should be adequate to support the required weight when being used to aid walking. The tip  24  may be constructed from a durable non-skid material that protects the end of the walking aid from damage, grips the ground surface, and cushions the shock of the walking aid  10  from repeated contact with the hard ground. The handle  22  may be constructed in a variety of styles know in the art, which may include a simple continuation of the shaft  20 , a bulbous knob, a semicircular curve, a cross-member, a 90-degree angle bend, a closed loop hand protector, and the like. The handle  22  may include a grip  26  to aid in holding the walking aid  10 , and the grip may include a rubberized sleeve, deformations in the contour of the exterior material of the handle  22 , leather bindings or coverings, deformable pads, and the like. The shaft  20  connects the handle  22  to the tip  24 . The length may be determined by the style of walking aid desired, and which may include a walking baton, standard cane, walking rod, crutch, quarter staff, etc. and the height and style of use desired by the user. The shaft  20  may also have length-adjusting mechanisms to customize the length. Such mechanisms may include connecting extenders, telescoping extensions, gradient-nesting armatures with locking connectors or pins, and the like. The shaft may also be hollow or have cavities for the integration of supplementary devices or may have conduits for connecting the devices to one another. 
     Supplementary features of the walking aid  10  may include a light source  42  integrated into the walking aid  10  with a portal to conduct the light from the light source  42  to exterior of the walking aid  10 . The light source illustrated in FIG. 3 includes an incandescent flash light bulb, but the invention is not so limited. For example, the light source may comprise a xenon bulb, a single or complex array of light emitting diodes, a cold cathode or florescent tube, and the like. The light source  42  may be protected by a light transmissive lens  40  that may be integrated into the exterior of the walking aid  10 . The light source may be controlled by a light control  62  or through the administrations of the timepiece  30 . The light source  42  may be electronically coupled to a self-contained power source  44  to provide power to the light source. The self-contained power source illustrated in FIG. 3 is depicted as a pair of replaceable batteries, but the invention is not so limited. For example, the self-contained power source may comprise a single or series of capacitors, a single or multiple rechargeable batteries, an electric fuel cell, and the like. The self-contained power source may be integrated into the walking aid  10  in a manner so that the self-contained power source could be replaced or recharged from outside the walking aid  10 . 
     An audio output device  50  may be provided that generates audio signals in response to the microprocessor  38  integrated in the timepiece  30 . Such signals may include an alarm signal to attract the attention of anyone in audible range, tone output from any of the supplementary devices it may be connected to, such as reminder alarms, low battery indication, low defensive substance warning, etc., voice or musical output from connected devices (such as voice output of time status from the timepiece  30 ), mileage from a connected electronic pedometer, or heart rate from a connected pulse meter. The audio output device may be integrated into the walking aid with a portal to conduct the sound from the audio output device  50  to outside the walking aid. The audio output device may be protected by a protective sound portal  54  that may comprise a series of holes, baffles, or screen material. The protective sound portal  54  may be integrated into the exterior of the walking aid  10 . The audio output device may be electronically coupled to a self-contained power source  44  to provide power. 
     Defensive substance dispenser  70  may be comprised of a container of a defensive substance  72 . For example tear gas, pepper spray, MACE, canine repeller, insecticide, chemical smoke, and the like. The defensive substance dispenser may be activated by the panic button  66  or through the administration of the microprocessor  38  integrated into the timepiece. The defensive substance container  72  may be coupled to a dispensing valve  74  which may allow the substance in the defensive substance container  72  to flow from the container to one or more nozzles  76 . The defensive substance container  72  may be located in the walking aid  10  in such a manner that the container could be replaced or recharged from outside the walking aid  10 . The valve may be activated by the spray control  64 . One or more nozzles  76  may be mounted on the exterior of the walking aid in locations convenient for use. In the illustrations, two nozzles are located on the shaft  20  near the tip  24  so the user may maintain a good distance between the user and the spray nozzles, although the invention is not so limited. For example, a nozzle could be located near the handle for use if the user was in such close proximity to an assailant that maneuvering the end of the walking aid toward the assailant&#39;s face may prove impossible. Optionally, several nozzles may be located along the length on the shaft for dispensing a substance to repel insects. 
     Controls  60  to administer to the supplementary features of the walking aid may be integrated into the walking aid and may include a light control  62 , a defensive substance spray control  64 , a panic button  66 , timepiece control  68 , and etcetera. The controls  60  may be mounted on the exterior of the walking aid near the handle for quick and easy access by the user. In the illustrations, the controls  60  are buttons mounted on the exterior of the shaft  20  just below the handle  22 , although the invention is not so limited. For example, the controls may be concealed under a hinged or sliding plate to hide the true nature of the walking aid  10  or to reduce the possibility of unintended actuation. The controls could also be integrated into the grip or the shaft itself so that the user may need to twist a section of the shaft  20  to activate the associated function. The control actuator may take the form of buttons, knobs, sliders, levers, motion or shock or orientation sensors, auditory systems for voice control, and the like. 
     A timepiece  30  may be integrated into the walking aid  10  to provide time keeping functions (such as time of day, stop watch timing, reminder alarm function, etc.). The timepiece may be, for example, comprised of several functional circuit sets integrated into a single integrated circuit chip. Examples of such chips are used in the construction of digital watches. The functional elements of such a chip may comprise a real time clock  34 , a micro-processor  38 , digital memory storage circuits  36  hereafter referred to as memory  36 , a LED or LCD controller, input devices hereafter referred to as timepiece controls  68 . The timepiece may be communicatively coupled to a visual output device comprising a display device  46 . The display device  46  may output information generated or stored within the timepiece  30 . The display device  46  itself may comprise an LED, LCD, gas plasma or CRT display. The timepiece  30  may be connected via electrical signal conductors or power conductors to the various supplementary features of the walking aid  10  to manage, monitor, or record the functions of the supplementary devices. For example, the timepiece may manage the recharging of the self-contained power supply via the microprocessor controlling as charging circuit. The timepiece  30  may monitor the programmed reminder alarm schedule stored in memory  36  to sound a tone or recorded voice message through the audio output device  50  at the appropriate time. The timepiece may record the time that any supplementary feature was activated by detecting the features activation via power utilization or by actuation of the controls  60  and store the time and features identity in it&#39;s memory  36 . The time piece may have the ability to display any of the information stored, or generated via the display device and enable the user to program the functions of the timepiece  30  or the functions of the supplementary devices through use of the timepiece controls  68 . The timepiece controls  68  may comprise a simple set of buttons similar to a digital watch or be as elaborate as a touch sensing display for handwritten or cursor controlled input. 
     In use, the functions of the walking aid  10  may provide a variety of utilities. Primarily it may aid the user in walking by providing additional stability allowing the user to reapportion weight to an additional support in contact with the ground. Further, the supplementary functions may include the following. The light  42  may be used to illuminate poorly lit areas, flashing brightly when the panic button was activated or blinking when a scheduled reminder initially announced by a tone from the audio output device  50  is not acted on. The audio output device  50  may sound a highly noticeable alarm when the panic button  66  is activated, emitting a tone to remind a person of a programmed appointment stored in the memory  36  of the timepiece  30  or to notify the user that the self-contained power supply may be getting low on power. The defensive substance dispenser  70  may emit a spray or cloud of defensive gas, liquid or other air born particulates when the spray control  64  is activated or in response to the microprocessor  38  of the timepiece  30  when through the timepiece controls  68  or other sensing means detects that the walking aid  10  has been stolen. The timepiece  30  may provide a display of the current time or stop watch capabilities on the display device  46  available to the user, the use of pre programmed reminder alarms to remind the user of appointments or other events through tones generated by the audio output device  50  or lighting effects generated by the light source  42 . The timepiece may also provide recordation of the times when the various features of the walking aid are activated by recording their activation in the memory  38  of the timepiece  30 . 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
