Filed: 1999-07-29
Abstract: Disclosed is a method which enables energy to be optimized in a motor vehicle or a train, using spare time slots in a timetable. According to the inventive method, the overall route between a point of departure when stopped and a stopping point upon arrival is subdivided into several sections, whereby each section is provided with a time slot. A single part of said route which is limited in distance and consists of a given number of sections is considered for optimization purposes in order to obtain an energy-saving method of travel, using an optimizing algorithm. The results of said optimization are only determined for the first section of part of the route. The optimization calculation is repeated in a cyclic manner during the travel of the vehicle/train. The part of the route which is thus considered changes as the vehicle moves.

Abstract: An optical intensity modulator (10) for high-speed RZ and NRZ data modulation based
on a balanced three-arm Mach-Zehnder interferometer. The three arms (60, 62, 64) are
joined at the input and output sides of the device by three-way couplers (12, 14). The
input coupler is structured to couple approximately equal powers into the first and
third arms (60, 64) and no more than 50% power into the second arm (62). In the
straight sections of the arms, there is arranged an AC electrode structure (40) for
applying an RF modulation signal and a DC electrode structure (30) for biasing the
device at a working point. The AC electrode structure is arranged so that an applied
modulation signal induces a negative phase shift (-Δ) in the first arm in relation to
the second arm and a positive phase shift (+Δ) in the third arm in relation to the
second arm. Large notch widths of up to 12 times the notch width of a conventional
two-arm Mach-Zehnder modulator are achievable. The device is characterised by
high tolerance to variations in the RF modulating signal and the power splitting ratio
into the interferometer arms. The intensity transfer function for a 25:50:25 power
split between the arms is comparable to that of two cascaded balanced two-arm Mach
Zehnder interferometers, but has the advantage of being a one stage device, which is
shorter and requires only one RF drive circuit.
