Patent number: 10627526Abstract: A position is determined using GNSS (Global Navigation Satellite Systems) with an antenna assembly having a number of antennas that are oriented with different direction vectors. Antenna-received signals are supplied to an evaluation assembly, which includes GNSS receivers and an evaluation device. The antenna-received signals are detected with regard to their satellite-related signal-to-noise ratio and, in relation to each satellite, the satellite-specific signal-to-noise ratio measured values that are positively distinguished in their signal-to-noise ratio from other signal-to-noise ratio measured values relating to the same satellite are selected. A satellite-related main direction vector signal is formed from each of the direction vector signals of the antennas. The main direction vector signals are compared with the orientation vector signals that characterize the position of the respective satellites in orbit; in the event of minor deviations a position indication is given.Type: GrantFiled: February 22, 2016Date of Patent: April 21, 2020Assignee: Siemens Mobility GmbHInventors: Hendrik Ibendorf, Olaf Richter

Patent number: 9948154Abstract: An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.Type: GrantFiled: October 2, 2015Date of Patent: April 17, 2018Assignees: Buhler Motor GmbH, MELECS EWS GmbH & Co.
