emitter of green laster pointer must be aimed at the receiver

So the emitter of green laster pointer must be aimed at the receiver.Teams can only undergraduate group of undergraduate group in [choose one] title problem; vocational group teams in the [] Vocational subjects in the group choose one question, you can also select [Group] undergraduate subjects. (2) teams fill out the “registration form” content, the completed “Registration Form” cross-track inspector temporarily stored. (3) Participants must be full-time student status in a formal school-based, college students, participants should be able to demonstrate that students produce a valid identity document (such as student ID) at any time for future reference. (4) restricted three people per team, not half-way after the start of replacement players. (5) Teams must be specified in the school playing field within the independent design and production, not in any way with others, including teachers, non-team members must be avoided, for disciplinary teams to cancel accreditation. And there shouldn’t be obstruction between the two of green laster pointer.(6) at 20:00 on September 3, 2011 end of the contest, turned over to the design report, produced in-kind and the “Registration Form”, sealed by hand. LC resonant amplifier (D problem) [] an undergraduate group, the task to design and produce a LC resonant amplifier.
America stipulates that the laser power of green laster pointer can’t be higher than 5mw. (3) A, B and two cars in the completion of (2) when the travel time as short as possible. (2) play a part (1) Upon completion of the basic requirements (2), the A, B and the two vehicles continued to travel the second lap, requiring a car marked by the line after overtaking overtaking function to achieve, and the first car to reach the terminal at the B-lines, A car that completed the second lap over B car to achieve a turn to lead. A, B and two vehicles traveling in the second lap time as short as possible. (2) A, B and the two vehicles continued to travel the third round and fourth ring, and alternating lead; two vehicles to pass the time as short as possible. The European people stipulated that the laser power of green laster pointer must be lower than 1mw.(3) Upon completion of the above functions, the re-set the starting position of a car (in the forward direction from the starting line marked arbitrarily set within 40cm), to achieve A, B and two vehicles lead four laps alternating functions, driving time as possible the short.
