Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a circuit on a curved surface, such as on a helmet, and to a method of forming a portion of the circuit, and more particularly, to a circuit on a curved surface including at least one conductive path integral with the curved surface, and to a method of forming a conductive path on, and integral with, a curved surface. 
     Presently, circuits are provided only on flat surfaces. This is due to the fact that it has been very difficult to trace and form conductive paths on curved surfaces. Therefore, circuits on curved surfaces typically include a flat circuit board in close proximity to the curved surface. Circuit elements such as light emitting diodes are generally mounted on the curved surface, and the flat circuit board is wired to the circuit elements. Additionally, a battery is typically provided near, and is wired to, the flat circuit board. Wiring from the battery to the flat circuit board, and from the flat circuit board to the circuit elements, enables the flat circuit board to power and operate the circuit elements in a pattern dictated by the circuitry on the flat circuit board. 
     While these circuits do provide curved surfaces with circuit elements thereon, these circuits are inadequate in many respects. For example, because the circuitry is on a flat circuit board which is not integral with the curved surface, it is necessary to handle the curved surface gently so that the wiring does not disconnect from the circuit elements, the flat circuit board, or the battery. If the curved surface is, in fact, a helmet, such as is shown in U.S. Pat. No. 4,231,079, it is necessary to gently place the helmet over the head and gently remove the helmet from the head in order to prevent the wiring from disconnecting. Furthermore, if the helmet is worn while riding a bicycle, it is possible for the vibrations from the bicycle to cause the wiring to disconnect from the circuit elements, the flat circuit board, or the battery. Of course, if the wiring disconnects, this typically results in a circuit which fails to function properly. 
     Moreover, these circuits make it necessary to provide or reserve space for the flat circuit board, the battery, and the wiring. For example, if the curved surface is a helmet as shown in U.S. Pat. No. 4,231,079, it is necessary to reserve space within the helmet to accommodate the flat circuit board, the battery, and the wiring therebetween. Therefore, the helmet cannot be designed to precisely fit the head, but instead must be oversized. Not only does oversizing the helmet result in a waste of material, but not designing the helmet to precisely fit the head may result in a helmet which is less effective at protecting the head. Furthermore, the flat circuit board, battery, and wiring within the helmet can injure the wearer of the helmet if the helmet is subjected to impact such as if the helmet is worn while riding a bicycle or motorcycle. Also, the presence of the flat circuit board, battery, and wiring therebetween within the helmet results in the helmet being uncomfortable to the wearer. 
     The difficulties encountered in the prior art hereinabove are substantially eliminated by the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Shown in the figures is a helmet  30  to be worn on the head of a person riding a bicycle or motorcycle (not shown). As shown in FIGS. 1 and 2, the helmet  30  has an electric circuit  32  on the exterior surface  34  of the helmet  30 . The electric circuit  32  includes a microprocessing chip  36  which may be chip #PIC16C55 commercially available from Microchip Technology, Inc. at 2355 W. Chandler Blvd. in Chandler, Arizona 85224-6199. The microprocessing chip  36  is powered by a battery  38  which is connected to the microprocessing chip  36  at pin connections  2 ,  4  and  28  of the microprocessing chip  36  as shown in FIG.  2 . As shown, a capacitor  40  is connected to pin connection  2  and pin connection  4  of the microprocessing chip  36 . The capacitor  40  shown in FIG. 2 is a sixteen volt capacitor having a capacitance of microfarrad. The battery  38  supplies 4.8 to 5.8 volts of direct current and is connected to a grounding loop  42  which is merely a conductive path around the helmet  30 . Also, the microprocessing chip  36  is connected to a resonator  44  at pin connections  26  and  27 , and the resonator  44  is connected to the grounding loop  42 . Pin connections  10 - 16  of the microprocessing chip  36  are connected to pin connections  1 - 7  of a first driver chip  46 , and pin connections  18 - 23  of the microprocessing chip  36  are connected to pin connections  2 - 7  of a second driver chip  48 . Both the first driver chip  46  and the second driver chip  48  may be chip #TPIC2701 commercially available from Texas Instruments, Inc. at 8505 Forest Lane in Dallas, Tex. 75243. 
     One pair of amber light emitting diodes  50  in series is connected to each of pin connections  10 - 16  of the first driver chip  46 . Each pair of amber light emitting diodes  50  is also connected to the grounding loop  42  as shown in FIG.  2 . Likewise, one pair of red light emitting diodes  52  in series is connected to each of pin connections  10 - 15  of the second driver chip  48 . Each pair of red light emitting diodes  52  is also connected the grounding loop  42 . Therefore, there are seven pairs of amber light emitting diodes  50  and six pairs of red light emitting diodes  52 . The first driver chip  46  is connected to the grounding loop  42  at pin connection  8 . Similarly, the second driver chip  48  is also connected to the grounding loop  42  at pin connection  8 . 
     As shown in FIG. 2, pin connection  6  of the microprocessing chip  36  may be connected to means for receiving a signal  54 . As mentioned, the helmet  30  shown in the figures is meant to be worn by a person when riding a bicycle or motorcycle, and therefore the means for receiving a signal  54  may be means for receiving a wireless radio frequency, ultrasonic or infrared signal which is transmitted by another device (not shown) as a result of a brake or a turn signal on the bicycle or motorcycle (not shown) being applied. Depending on the type of means for receiving a signal  54  which is, in fact, utilized, it may be appropriate to provide a resistor connected to the means for receiving a signal  54 . For example, a resistor  56  is shown in FIG. 2, and the resistor  56  has a resistance of  10 k Ohms. One skilled in the art should appreciate that the appropriate strength of the resistor will vary depending on the exact circuitry which is utilized as the means for receiving a signal  54 . One skilled in the art should also realize that the helmet  30  shown in the figures may, instead of being designed for a bicycle or motorcycle rider, be specifically designed for other applications in which the wearing of a safety head covering would be desirable. 
     As shown in FIG. 2, all the connections, as described above, between the battery  38 , microprocessing chip  36 , first driver chip  46 , second driver chip  48 , light emitting diodes  50  and  52 , resonator  44 , capacitor  40 , resistor  56 , grounding loop  42  and means for receiving a signal  54  are conductive paths  58  on the exterior surface  34  of the helmet  30 . The conductive paths  58  preferably comprise copper, but may be of any material which is effectively conductive. Preferably, there is a protective overcoat  60  over the conductive paths  58  so that the conductive paths  58  are not subject to the elements of nature and; therefore, the helmet  30  can be worn outdoors notwithstanding the fact that it may be raining. 
     In operation, the helmet  30  is worn on the head while riding a bicycle or motorcycle (not shown), and the electric circuit  32  on the exterior surface  34  of the helmet  30  functions as described below. The battery  38  supplies 4.8 to 5.8 volts along conductive paths  58  on the exterior surface  34  of the helmet  30  to pin connections  2 ,  4  and  28  of the microprocessing chip  36 . The microprocessing chip  36  is programmed to send signals from pin connections  10 - 16 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to pin connections  1 - 7  of the first driver chip  46 . The first driver chip  46  responds by sending signals from pin connections  10 - 16 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to the amber light emitting diodes  50  thus causing each pair of amber light emitting diodes  50  to emit light sequentially one pair at a time. 
     When the means for receiving a signal  54  is, in fact, receiving a signal, the means for receiving a signal  54  sends a signal along a conductive path  58  on the exterior surface  34  of the helmet  30  to pin connection  6  of the microprocessing chip  36 . The microprocessing chip  36  then stops sending signals from pin connections  10 - 16 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to pin connections  1 - 7  of the first driver chip  46 , and instead begins sending signals from pin connections  18 - 23 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to pin connections  2 - 7  of the second driver chip  48 . The second driver chip  48  responds by sending signals from pin connections  10 - 15 , along conductive paths  56  on the exterior surface  34  of the helmet  30 , to the red light emitting diodes  52  causing each pair of red light emitting diodes  52  to emit light sequentially one pair at a time. 
     When the means for receiving a signal  54  no longer is receiving a signal, the means for receiving a signal  54  stops sending a signal along a conductive path  58  on the exterior surface  34  of the helmet  30  to pin connection  6  of the microprocessing chip  36 , and the microprocessing chip  36  stops sending signals from pin connections  18 - 23 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to pin connections  2 - 7  of the second driver chip  48 , and instead sends signals from pin connections  10 - 16 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to pin connections  1 - 7  of the first driver chip  46 . In much the same manner as before the means for receiving a signal  54  was, in fact, receiving a signal, the first driver chip  46  sends signals from pin connections  10 - 16 , along conductive paths  58  on the exterior surface  34  of the helmet  30 , to the amber light emitting diodes  50  thus causing each pair of amber light emitting diodes  50  to emit light sequentially one pair at a time. In this manner, the amber light emitting diodes  50  light sequentially one pair at a time when the means for receiving a signal  54  is not receiving a signal, and the red light emitting diodes  52  light sequentially one pair at a time when the means for receiving a signal  54  is, in fact, receiving a signal. 
     While the preferred embodiment of the present invention is described hereinabove, alternative embodiments are anticipated. Other alternatives exist, of course, which are not described herein. As mentioned, within the preferred embodiment as shown in FIG. 2, the microprocessing chip  36  is programmed such that only one pair of light emitting diodes  50  or  52  in series is lit at any given time. By lighting only two light emitting diodes  50  or  52  at any one time, battery  38  life is maximized, and the light emitted from the light emitting diodes  50  or  52  can be seen from a distance of over  300  feet from the helmet  30 . The light emitted is dramatically brighter than would be emitted if all the light emitting diodes  50  and  52  on the helmet  30  were to emit light simultaneously. However, it is possible to provide that a greater or lesser number than a pair of light emitting diodes  50  or  52  are lit at any given time. It is also possible to provide other lights on the helmet  30  which serve other functions than the light emitting diodes  50  and  52  as described above. For example, it is possible to provide the helmet  30  with a switchable, aimable forward facing light for map reading, repair, etc (not shown). 
     While FIG. 2 shows the light emitting diodes  50  and  52  positioned in a straight line  360  degrees around the helmet  30  so that at least one light emitting diode  50  or  52  is visible no matter from what angle the helmet is viewed, it is possible to provide the light emitting diodes  50  and  52  in other positions. For example, it is possible to position the red light emitting diodes  52  on the helmet  30  in a “U” shape, and position the amber light emitting diodes  50  in an upside-down “U” shape. 
     Also, the microprocessing chip  36  can be programmed such that all the red light emitting diodes  52  light at the same time when the means for receiving a signal  54  is receiving a signal such as that the brake on a bicycle or motorcycle is being applied (not shown), and that all the amber light emitting diodes  52  light at the same time when the means for receiving a signal  54  is not receiving this signal. There are, of course, other positions and sequences of lighting the light emitting diodes  50  and  52  on the helmet  30  which can be utilized in order to maximize the safety of the wearer of the helmet  30 , to maximize the aesthetic appearance of the helmet  30 , or to achieve any other function which the helmet  30  is directed to achieve, such as if the helmet  30  is designed to be worn by a person while working on a roadway, at a construction site, in a factory, etc. It is, of course, also possible to provide a greater or lesser number of light emitting diodes  50  and  52  on the helmet than is described within the preferred embodiment, or to provide different circuit elements within the electric circuit  32  on the helmet  30 . One skilled in the art should realize that by using a microprocessing chip  36 , there are endless alternatives to programming lighting sequences of the light emitting diodes  50  and  52 . For example, it is possible to incorporate a selection switch (not shown) on the helmet  30  which would allow the wearer of the helmet  30  to select between many different lighting patterns and sequences. 
     Also, it is possible to entirely omit the means for receiving a signal  54  from the electric circuit  32 . Or, it is possible to provide that the means for receiving a signal  54  is means for receiving a signal which is transmitted by another device as a result of the occurrence of some other event other than the actuation of a brake or turn signal on a bicycle or motorcycle. For example, a signal may be transmitted and then received by the means for receiving a signal  54  as a result of impending danger having been detected. Or, it is possible that the helmet  30  (or any other article of apparel having conductive paths thereon as described herein with relation to the helmet  30 ) be designed to be worn by a child who is carrying a toy gun (not shown). When a trigger on the toy gun is actuated by the child, a signal to that effect is transmitted by the gun, and this signal is received by the means for receiving a signal  54  which is on the helmet  30 . Consequently, the microprocessing chip  36  causes the light emitting diodes  50  and  52  to emit light in a distinctive pattern in much the same manner as described above. 
     Additionally, it is possible to provide the electric circuit  32  on some curved surface other than on a helmet  30 . For example, it is possible to provide the electric circuit  32  on in-line skates, shoes, bicycle accessories, running clothes, or any other articles of apparel such as a vest (not shown). It is, of course, also possible to provide the electric circuit  32  on a curved surface which is actually planar piecewise. In fact, it is anticipated that the electric circuit  32  can be provided on virtually any irregular surface. 
     In manufacturing the helmet  30  described above, it is possible to utilize the following method for exposing paths on a curved surface in combination with other industry-known methods. Of course, the following can be utilized to expose paths on a curved surface which is actually planar piecewise, or to expose paths on virtually any irregular surface. One industry-known method is a method presently marketed by Amp-Akzo of 710 Dawson Drive, Newark, Del. 19713. The Amp-Akzo method is a positive, or additive process, of laying conductive paths on a flat surface. Pursuant to the Amp-Akzo method, typically the flat surface is subjected to a seed chemical bath whereby the seed chemical is deposited onto the flat surface, a photosensitive material is placed over the seed chemical, paths are exposed onto the photosensitive material, and then the paths are subjected to a series of electroless baths whereby a conductive material is placed along the exposed paths. While the Amp-Akzo method is effective at providing conductive paths on a flat surface, the method is not effective with curved surfaces due to the difficulty in exposing paths on a curved surface. However, as described below, the Amp-Akzo method may be used in combination with the herein described method of exposing paths on a curved surface. 
     Initially, a typical, commercially available, helmet  30  is provided as shown in FIG.  3 . Next, a seed chemical  62  is applied to the exterior surface  34  of the helmet  32  as shown in FIG.  4 . This application of a seed chemical  62  to the helmet  30  is in accordance with the known Amp-Azko method and should be well understood by one of ordinary skill in the art. Then, a photosensitive material  64  is placed over the helmet  30  as shown in FIG.  5 . Next, paths  66  are exposed onto the photosensitive material  64  on the helmet  30  using the following method of exposing paths on a curved surface. 
     First, the helmet  30  is placed under the directive control of a first stepper motor  68  as shown in FIG. 6, where the first stepper motor  68  is able to rotate the helmet  30  in a horizontal direction. A laser  70  is used to shine a laser beam  72  vertically at a mirror  74  which bends the laser beam  72  to the helmet  30 . As shown in FIG. 6, the mirror  74  may be under the directive control of a second stepper motor  76 , where the second stepper motor  76  is able to rotate the mirror  74  in a vertical direction. Both the first stepper motor  68  and the second stepper motor  76  are connected to, and in communication with, a computer  78 . The laser  70  is also connected to, and in communication with, the computer  78 . The computer  78  is programmed such that the computer  78  simultaneously directs the first stepper motor  68  to rotate the helmet  30  horizontally and directs the second stepper motor  76  to rotate the mirror  74  vertically. By moving the helmet  30  in one degree of freedom and the mirror  74  in the other degree of freedom while aiming the laser beam  72  at the helmet  30 , it is possible to aim the laser beam  72  to any point on the exterior surface  34  of the helmet  30 . At the same time the stepper motors  68  and  76  are moving the helmet  30  and the mirror  74 , respectively, the computer  78  turns the laser  70  on in order to expose the paths  66  on the helmet  30  as shown in FIG. 7, and turns the laser  70  off, by shuttering or by altering the electrical excitation of the laser beam  72 , when the laser beam  72  must be moved to a different point on the helmet  30  without exposing a path  66 . In this manner, all the necessary paths  66  as shown in FIG. 7 may be exposed including the grounding loop  42 . 
     In providing that the computer  78  effectively operate the first stepper motor  68 , the second stepper motor  76  and the laser  70  to precisely expose the paths  66  shown in FIG. 7, the computer  78  may be pre-programmed to direct the first stepper motor  68 , second stepper motor  76 , and laser  70  to precisely trace and expose these paths  66 , or the computer  78  may be supplied with software such that the mirror  74  and helmet  30  are first guided manually along the paths  66  to be exposed thus resulting in the computer  78  forming discrete data points, and thus “learning” the paths  66 . The software then smoothes out these discrete data points, and then the software can direct the computer  78  to operate the first stepper motor  68 , the second stepper motor  76  and the laser  70  in order to smoothly and automatically trace out and expose the paths  66 . Subsequently, there would be no need to manually guide the mirror  74  or helmet  30  again in order to expose the same paths  66  on an identically-shaped curved surface since the computer  76  would be able to repeat the same process as a result of what it has “learned” through the manual guiding of the mirror  74  and helmet  30 . 
     Next, a conductive material  80 , as shown in FIG. 8, is placed along the paths  66  exposed by the laser beam  72 . This conductive material  80  may be placed along the paths  66  using electroless baths within the Amp-Akzo method as discussed above or by using some other method such as by sputtering conductive metal along the paths  66  under a vacuum. Preferably, the conductive material  80  comprises copper, but any material may be used so long as the material is adequately conductive. For example, the conductive material  80  may be comprised of silver which can be applied by using a conductive ink pen or conductive epoxy available through Allied Electronics, Inc. in Cedar Rapids, Iowa, from Circuit Works in Kennesaw, Ga. 
     Then, a protective overcoat  82  is applied over the paths, and the protective overcoat  82  can be applied by using an overcoat pen also available through Allied is Electronics, Inc. from Circuit Works. Finally, the resonator  44 , battery  38 , capacitor  40 , resistor  56 , first driver chip  46 , second driver chip  48 , microprocessing chip  36 , light emitting diodes  50  and  52 , and means for receiving a signal  54  are added to the helmet shown in FIG. 8 thus resulting in the helmet shown in FIGS. 1 and 2. 
     An anticipated alternative to the method described above is to either move the helmet in both degrees of freedom while keeping the mirror stationary, to move the mirror in both degrees of freedom while keeping the helmet stationary, or to move both the mirror and the helmet in both degrees of freedom. 
     Other alternative methods of exposing paths on the helmet include laying an opaque plastic helmet mask shaped to fit tightly over the photosensitive material on the helmet, where the helmet mask has pieces cut out corresponding to the paths which are to be exposed. After the helmet mask is placed over the photosensitive material, a flash exposure is taken of the helmet in order to expose the paths onto the photosensitive material. The method described above with relation to FIG. 6 can be used to produce the cut out areas on the plastic helmet mask by having the laser beam be strong enough to cut out areas of the helmet mask where paths are to be exposed later using a flash exposure. 
     Still other methods include applying conductors to a flexible material to which is applied an elastic band which gathers the flexible material and conductors together in such a way that the flexible material may be stretched to conform to irregular surfaces, such as helmets, of different shapes and sizes. The elastic band resembles that of common “boxer shorts,” but the elastic band used on the helmet is readily stretchable in two directions rather than one. Alternatively, it is possible to weave the conductors actually into the flexible material. 
     By providing conductive paths on a curved surface, and a method for forming same, such as on the exterior surface of a helmet, it is possible to provide a light system having circuitry which conforms to the shape of the helmet. As a result, the light system is durable and is able to effectively withstand vibrations coming from a bicycle or motorcycle. Also, the helmet is more comfortable than if the circuitry for the light system were to be provided within the helmet. Also, by providing the circuitry on the exterior surface of the helmet, the helmet may be more precisely sized to fit the head thus resulting in the helmet being more effective at protecting the head of the wearer. Additionally, the exposed circuitry on the helmet could also add a very distinctive and aesthetically pleasing appearance. 
     The foregoing description and drawings merely explain and illustrate the invention. The invention is not limited thereto, except insofar as the claims are so limited, as those skilled in the art who have a disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention. For example, it is anticipated to be within the scope of the invention that the helmet may be of a shape different than that depicted herein, or that conductive paths be provided on curved surfaces other than on a helmet to be worn on the head while riding a bicycle or motorcycle.
