Abstract: A detection system for a vehicle, including at least one detection device operable for detecting objects in a detection area. The detection device also includes a first emission antenna, a first reception antenna, and a plurality of extension portions. One of the plurality of extension portions is integrally formed as part of the first emission antenna, and another of the plurality of extension portions is integrally formed as part of the first reception antenna. The first emission antenna generates an emission wave at a predetermined angle which contacts objects in the first detection area and deflects of the objects in the first detection area, and returns to the first reception antenna as a return wave. In an embodiment, the first emission antenna includes at least one Vivaldi wing, and the first reception antenna includes at least one Vivaldi wing.

Abstract: A three-magnet assembly configured for use in a position sensing system is disclosed. In an example, the three-magnet assembly establishes a non-linear spatially varying magnetic field configured to be measured by a magnetic field measurement device so that resolvable measurements are spatially distributed in a non-linear fashion. The resolvable measurements are distributed to a relatively higher concentration in at least one first region along a measurement stroke and to a relatively lower concentration in at least one second region along a measurement stroke, the second region being different from the first region. In an example, the different concentrations of resolvable measurements are utilized to spatially vary the precision of a position sensor along a measurement stroke. A system and methods for correlating magnetic field measurements to expected positions are also disclosed.

Abstract: An inductive position sensor determines a position of an object. The sensor incudes a circuit board, a wire source coil constructed and arranged to provide a certain operating frequency, a first wire sensing coil, and a second wire sensing coil. The source coil, and first and second sensing coils are embedded in the circuit board, and each of the first and second sensing coils are constructed and arranged to provide an output as the object passes by source coil and the first and second sensing coils. Eddy current generating material is associated with any of the coils so as to provide an eddy current that interferes with wire to wire communication between the sensing coils and the source coil, so as to alter the output of the sensing coils to improve accuracy of the sensor to shape the output.
