  • Patent number: 8131501
    Abstract: An analyzing method for a sensor system determining the position of a shifting fork in a shift transmission is suggested wherein a shifting fork can be moved from a neutral position into at least one gear position. The position of the shifting fork is determined by a sensor system comprising at least one magnet and at least one magnetic field sensor that can be moved relative to the magnet. The method includes storing a base diagram for a base output signal in relation to position s and correcting the measured output signal so that the base diagram can be used for determining with high accuracy the position of the shifting fork.

  • Patent number: 7224986
    Abstract: A method of evaluating a location of a mobile station within a cellular telecommunication system is described. A cell is associated with a base station (BS). The mobile station (MS) is located within the cell. A timing advance (TA) is evaluated by the base station (BS). The method comprises the following steps: evaluating a direct distance (rd) between the mobile station (MS) and the base station (BS) for a number of locations (L) of the mobile station (MS) within the cell, evaluating common values depending on the direct distances (rd), and evaluating an estimated direct distance (rd*) of the mobile station (MS) from the base station (BS) depending on the common values.

  • Publication number: 20060109935
    Abstract: A receiver system of a wireless communication system comprising means for receiving and decoding of punctured convolutional codes and characterized by comprising a soft-decision processing unit adapted to receive a number of quantized signal soft-decision values spread across a range, the range having a maximum value, a minimum value, and a value corresponding to the center of that range; shift a number of signal soft-decision values by a shift step away from said center value; and quantize the signal soft-decision values with fewer bits than the number used to quantize the received signal soft-decision values according to a determined quantization input-output relationship.

  • Publication number: 20040162091
    Abstract: The present invention relates to a method of determining a quality measure of a position measurement method for a cellular telecommunication network, the method comprising the steps of: identification of a first measurement area having at least a predefined number of neighbouring first cells, the first measurement area belonging to a selected class of measurement areas, defining of first sub-areas in the first measurement area by applying a predefined grid on the first measurement area, performing position measurements by means of the position measurement method in at least a sub-set of the first sub-areas, determining of measurement errors for the position measurements, determining of the quality measure based on the measurement errors.

  • Publication number: 20030098811
    Abstract: In a method of estimating the position of a mobile station (2) in a mobile radio network (1) on the basis of propagation models, at the mobile station (2) the field strength of a plurality of base stations (6-8) connected to the mobile station (2) is measured, the distance between the mobile station (2) and each of the base stations (6-8) connected to the mobile station (2) is estimated on the basis of a propagation model, and the estimated distances are stored, the estimated distances being filtered and the position of the mobile station (2) being estimated on the basis of the filtered estimated distances. In a further development the propagation model used can be adapted on the basis of the measured field strengths. In this way a more accurate position determination of the mobile station (2) can be effected.

  • Publication number: 20030036379
    Abstract: The invention relates to a mobile radio network which provides location-based services to mobile subscribers. To simplify the use of location-based services within the mobile radio network, the network elements of the mobile radio network cause at least one of the base stations to transmit an indicator signal which indicates to the mobile subscriber that at least one location-based service is available. The mobile terminal disclosed receives the indicator signal and causes its display controller and the display connected thereto to generate a new symbol on the display which indicates to the mobile subscriber the availability of the location-based service.
