  • Publication number: 20170006249
    Abstract: Systems and methods which provide enhanced isolation for receivers using relatively simple and inexpensive modifications or additional circuitry at a receiving station. Embodiments augment a primary antenna of a receiving station with a correlated heterogeneous antenna element. Augmented antenna systems of embodiments provide an appreciable increase in front-to-back isolation with respect to desired signals received at a receiving station. Such augmented antenna systems are particularly useful in a high interference environment, such as an interference limited environment as may be experienced at the edge of two Single Frequency Networks (SFNs). For example, embodiments of an augmented antenna system may be utilized in situations in which positive carrier to noise ratio (C/N) conditions are present (e.g., more signal than noise is present in the desired signal and more signal than noise is present in the interfering signal).

  • Patent number: 6759604
    Abstract: A seat load measuring system for use in a vehicle occupant protection device for a vehicle seat has a zero point adjusting capability. The seat load measuring system comprises four weight sensor assemblies; a hub assembly for collecting the weight sensor outputs and providing an output determined by the weight sensor outputs; and means for communicating a user's desire for a zero point adjustment to each weight sensor assembly. Each weight sensor assembly includes a zero point adjusting section, which receives an output from the communication means for executing a zero point adjusting operation. If a zero point of a weight sensor assembly is not within a predetermined range, the zero point adjusting section may providing an alert. A zero point adjusting command may be entered by a command input device and passed to the zero point adjusting section. Alternatively, the zero point adjustment may be initiated through a momentary switch provided in the hub assembly.
