  • Publication number: 20120106975
    Abstract: Disclosed herein is a scheme for transmitting a composed optical signal 12b through an optical fiber arrangement 40. The transmitted composed optical signal 12b comprises one or several sidebands Sb1, Sbn each substantially centered around a subcarrier f1, fn, and an attenuated carrier signal ftb attenuated such that the composed optical signal 12b is not linearly detectable by means of optical direct detection. The transmitted composed optical signal 12b is received and the power of the attenuated carrier signal ftb is amplified so as to create an amplified composed optical signal 12a?; that is linearly detectable by means of optical direct detection.

  • Patent number: 7966117
    Abstract: A method for controlling rotation speed of at least one rotary element in the driveline of a vehicle is provided. At least one operating parameter is detected repeatedly, which operating parameter corresponds to an actual value of a torque in the driveline, which is delivered to the rotary element. A desired value of a torque to the rotary element is determined on the basis of friction against the ground of at least one of the ground engagement elements of the vehicle, which ground engagement element is driven via the rotary element. The rotation speed of the rotary element is controlled so that the actual value moves toward the desired value.

  • Patent number: 7844428
    Abstract: Method and arrangements for predicting life-affecting damage on a rotary member subjected to repeated loading during operation. A number of operating parameters are measured, and a temperature increase during each loading is calculated from the operating parameters. More precisely, a total temperature in a part of the rotary member is calculated for each loading by summation of basic temperature of the rotary member before the loading concerned and the temperature increase, and the values for the total temperature are used as a measure of the damage. The part of the rotary member for which the total temperature is calculated defines a surface that is acted on when the rotary member is loaded. Two sets of predetermined functions (M, N), which each comprise at least one function, are used for temperature-increase calculation, and the set which is used for temperature-increase calculation is selected depending on at least the nature of the rotary member.

  • Patent number: 7199870
    Abstract: A system and method for providing polarization-independent optical sampling utilizes a differential group delay (DGD) element to split a sampling pulse source (SPS) into orthogonal components by controlling the state of polarization of the SPS at the DGD element input. The orthogonally-polarized sampling pulse components then each interact with the input optical signal waveform in a polarization-dependent sampling gate, creating two samples for each original sampling pulse. The generated samples are converted into the electrical domain by a photodetector with an impulse response time longer than that associated with the DGD element, resulting in a single impulse response representing the combined energy of the two samples that is independent of the state of polarization of the input optical signal waveform.
