Abstract: An event sensing component includes a housing, wherein the housing includes a first tube that is provided along an entire length of the housing, and a second tube that is provided along the entire length of the housing. The housing also includes a first connector provided at one end of the first tube and configured to couple with a first bypass tube that is attached at another end to another traffic sensing component. The housing further includes a second connector provided at one end of the second tube and configured to couple with a second bypass tube that is attached at another end to the another traffic sensing component.

Abstract: An acoustic pulse transfer device according to the invention has one or more carrier segments that can be connected together to transport acoustic pulses through them. Acoustic pulses generated by events in a first segment are transported through a second segment, which may or may not have its own acoustic pulse generator generating acoustic pulses in response to different events. Acoustic pulses generated in the first and second segments are then independently transported through a third segment. Any number of such segments can be connected together. Typically, acoustic pulses are generated by compressing a pneumatic tube in a carrier segment. The pneumatic tube is connected to a substantially non-compressible acoustic pulse carrier tube connected to the segment's pneumatic tube through a trough in a wall separating the pneumatic tube from the acoustic pulse carrier tube.
