7. A printed circuit board comprising:
an insulated layer with a groove formed thereon;
a metallic substance formed on an inner side of the groove and on one side of the insulated layer; and
a first circuit pattern formed on at least one of another side of the insulated layer and the metallic substance formed on the groove.
8. The printed circuit board of claim 7, wherein the metallic substance is carbon-nanotube.
9. The printed circuit board of claim 7, further comprising:
a conductive bump formed on a portion of the first circuit pattern;
an insulating material stacked on the first circuit pattern such that the first circuit pattern is filled by the insulating material and the insulating material is penetrated by the conductive bump; and
a second circuit pattern formed on the insulating material.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
I claim:
1. A traffic signal control system employing universal coordinated time (UTC) of CPS as time base comprising
a core system for receiving UTC data of GPS, and to include longitude and latitude data and to convert the information to local time as a common time basis for the traffic signal control system.
2. The traffic signal control system of claim 1, further comprises a basic inputoutput system including a manual control device, manual data outputinput device, and a means of calculating rectified phase of a light signal switching.
3. The traffic signal control system of claim 1, wherein the manual control device of the basic outputinput system is a relay.
4. The traffic signal control system of claim 1, wherein the manual outputinput device is a box containing IR receiving and transmitting device which is set by portable computer following this interface.
5. The traffic signal control system of claim 1, wherein the manual outputinput device is a box containing a plasma monitor and a waterproof keyboard for setting.
6. The traffic signal control system of claim 1, wherein the calculating means is added with a new rectified phase for light signal switching control parameter so that the traffic signals synchronized at the same time.
7. The traffic signal control system of claim 1, wherein the selective secondary system includes (a) diode light source uninterrupted system; (b) fine time system of the vehicle flowrate sensor; (c) beehive wireless telephone being used as a non synchronized batch type loading wireless re-new setting system to form a complete disperse system control system.
8. The traffic signal control system of claim 1, wherein the vehicle flowrate sensor includes ultrasonic reflex type, microwave reflex type, sensing coil type, magnetic sensing type or optical imaging type.
9. The traffic signal control system of claim 1 or 7, wherein the beehive wireless telephone system divides 24 hour of a day into a plurality of interval, each interval being 10 to 15 as a basis, including being communication time interval and being free interval.
10. The traffic signal control system of claim 1, wherein the traffic signals include single light signal, having a satellite receiving system position to the single light to control synchronous flickering.
