摘要： The present invention is a radar system for detecting the presence of obstacles. The radar system includes at least one transmitting antenna and at least one receiving antenna. The transmitting antenna receives an input signal and transmits an electromagnetic wave. The electromagnetic wave reflects off an obstacle back to the receiving antenna. The receiving antenna captures the reflected electromagnetic wave and produces an output signal. The output signal is then combined with the input signal in a quadrature mixer. The resulting in-phase (I) and quadrature (Q) signals may be further processed and then transmitted to a processing system. The processing system uses a suitable algorithm, e.g., a back projection algorithm, to estimate the type and location of obstacles that reflected the electromagnetic wave. In an exemplary embodiment, the algorithm is adapted to discriminate between different sizes and locations of obstacles in order to determine if there is a hazard. Based on this information, the processing system then communicates with a visual and/or audible warning system in order to alert the driver about the obstacle if it has been determined to be a hazard.

摘要： An improved wire pattern layout for a window antenna that takes into account the characteristics of radio frequency current flow and the impact of a heater grid pattern. The wire pattern layout comprises a heating grid that is adapted to be in electrical communication with a DC power source. A plurality of antenna wires traverse the heating grid. The antenna wires are adapted to be in electrical communication with a feed to a radio frequency device such as an AM radio, a FM radio, an AM/FM radio, a CB radio, a cellular phone, a global positioning system, or combinations thereof. The antenna wires may extend across the heating grid in substantially straight lines or in a step-wise fashion. In addition, the antenna wires may change direction while traversing the heating grid. By taking into account the characteristics of radio frequency current flow and the impact of a heater grid pattern, the improved design of the wire pattern layout provides enhanced directional gain and impedance characteristics.

摘要： A dual band slot antenna for cellular telephone and GPS frequency bands. The antenna is a slot antenna formed in a conductive layer laminated to a layer of a windshield or other transparency. The slot is formed along two adjoining arcs of a circle extending oppositely from a feedpoint, with a portion of the conductive layer interposed between the ends of the slots. The two slot legs have different lengths so the slot is tuned to exhibit at least two resonant peaks, such as one at the cellular telephone frequency band and the other at the GPS frequency band. The slot is fed by strip line transmission lines or capacitive coupling, using additional conductive film patches spaced by one or more layers of the window, with the window layer forming a dielectric.
