    摘要: According to the invention, a monostatic FMCW radar sensor for a vehicle for detecting objects is proposed in which at least one antenna feed in combination with a dielectric lens is embodied for both transmitting and receiving a corresponding echo signal. At least one antenna feed is connected to a ring mixer via a ratrace ring or double ratrace ring, so that an expensive circulator can be dispensed with. The high-frequency structure is advantageously embodied in planar microstrip form. A plurality of transmission and reception antennas are focused via one common lens.

    摘要: A forward lean sock, that is particularly suited to snowboarding is provided. The snowboarding sock includes a woven sock body having a leg section and a foot section joined by a heel and front arch. The heel includes a Y-heel construction that provide an enhanced pouch of material at the heel to remove tension at the opposing front arch so that bunching is minimized in a forward lean position. The toe section can include reduced padding or a flat weave with no padding to provide more freedom of toe movement for the wearer.
