Abstract: A transmission range selection sensor includes a housing defining a bore extending along a central axis. A piston is slideably disposed within the bore. A magnet carrier is attached to and moveable with the piston. A magnet is supported by and moveable with the magnet carrier. A first magnetic sensor and a second magnetic sensor are supported by the housing and are spaced from each other along the central axis. A position of the magnet carrier along the central axis is determinable from a sensed magnetic flux from the first and second magnetic sensors. The sensor includes at least one magnetic flux concentrator attached to one of the magnet carrier or the housing. The flux concentrator is operable to concentrate the magnetic flux toward at least one of the first magnetic sensor or the second magnetic sensor depending upon a position of the magnet along the central axis.

Abstract: Slot antennas built into metallic body panels utilize the vehicle body itself as an antenna radiator. Building the slot antennas directly into the metallic body panels converts the vehicle body from functioning as an RF shield into an RF antenna, which significantly improves mobile communication reception for a wide range of RF communication devices. Different types of slot antennas may be included for different communication channels utilized by different types of devices. Multi-band slot antennas are configured to receive multiple bands within a larger frequency channel. Dual-polarity antennas are configured to receive signals propagating in a dual-polarity mode. Multiple slot components may be configured as multi-band, dual-polarity antennas. Each slot antenna may be passive (without an RF pickup) or active with an RF pickup and coaxial cable connecting the antenna to an electronic device, such as receiver or amplifier located inside or otherwise interconnected with the vehicle.

Abstract translation: 金属车身板内置的天线天线将车身本身用作天线辐射器。 将缝隙天线直接构建到金属车身面板中，将车体转换为RF屏蔽，成为RF天线，从而显着改善了广泛的射频通信设备的移动通信接收。 可以包括不同类型的时隙天线，用于不同类型的设备使用的不同通信信道。 多频带时隙天线被配置为在更大的频率信道内接收多个频带。 双极性天线被配置为接收以双极性模式传播的信号。 多个时隙组件可以被配置为多频带双极性天线。 每个缝隙天线可以是无源的（没有RF拾取）或者具有将天线连接到诸如位于车辆内部或以其他方式互连的电子设备的RF拾波器和同轴电缆的有源天线。
