Patent number: 7069021Abstract: A method is provided for determining the position of an electronic device by receiving a code modulated signal transmitted by satellites, and position information of the satellites and time data, and by generating local time data. In the method, delta range measurements are taken for at least four different satellites. For each of said at least four satellites, the velocity of the satellite is determined in relation to the positioning receiver. Furthermore, in the method, the delta range measurement results are replaced in an algorithm applying said delta range measurements and velocities to generate reference data for determining the local time data frequency error and the position. The local time data frequency error and the position are determined by searching for the minimum value of said reference data. A system and an electronic device applying the method are also provided.Type: GrantFiled: February 25, 2003Date of Patent: June 27, 2006Assignee: Nokia CorporationInventor: Antti Lehtinen

Patent number: 4574624Abstract: An ultrasonic echo sounding device permits observation of the web formation and/or the pulp suspension flow on the wire part and in the head box of a paper machine. The device includes a series of ultrasonic detectors connected to the wall of the flow channel in the head box and/or to the forming wire. The detectors direct an ultrasonic field at the pulp suspension layer, and the echo signals received from the pulp suspension layer are detected. The detectors operate as acoustic lenses so that the focal points thereof are located in the transverse direction of the pulp suspension flow and in the direction of thickness of the pulp suspension layer in a manner whereby information concerning fibre bundles, air bubbles, variations in consistency, corresponding parameters and their variations in the transverse direction of the pulp suspension flow and in the direction of thickness of the pulp suspension layer are indicated by the device.Type: GrantFiled: June 22, 1984Date of Patent: March 11, 1986Assignee: Valmet OyInventors: Antti Lehtinen, Seppo Lepisto
