An antenna system for a vehicle including a front windshield glass and a rear windshield is disclosed. The antenna system comprises an antenna unit including a radiating element electromagnetically coupled to an excitation element. The radiating element is coupled to the front windshield glass, and the excitation element is positioned on a passenger compartment interior surface of the front windshield glass. The antenna system also comprises a high-gain antenna unit including first radiating elements, a second radiating element, a 90-degree phase shift circuit, and a low noise amplifier that is coupled to the phase shift circuit. The first radiating elements receive signals through the rear windshield glass. The antenna unit and the high-gain antenna unit may function in a diversity antenna configuration.
Abstract:
The invention is directed toward a magnetic valve reader used as an indicator tool. The magnetic valve reader determines a location and an orientation for a magnetic indicator device to indicate a device setting of an implantable medical device. The implantable medical device includes the magnetic indicator device coupled to a valve on the implantable medical device. External magnetic fields, specifically the Earth's magnetic field, may interfere with the compass and create an incorrect device setting indication. The electronic reader estimates the external magnetic fields to subtract the estimate from received data to minimize any influence that external magnetic field has on the accuracy of the device setting measurement.
Abstract:
A multi-channel digital transceiver (400) receives uplink radio frequency signals and converts these signals to digital intermediate frequency signals. Digital signal processing, including a digital converter module (426), is employed to select digital intermediate frequency signals received at a plurality of antennas (412) and to convert these signals to baseband signals. The baseband signals are processed to recover a communication channel therefrom. Downlink baseband signals are also processed and digital signal processing within the digital converter module (426) up converters and modulates the downlink baseband signals to digital intermediate frequency signals. The digital intermediate frequency signals are converted to analog radio frequency signals, amplified and radiated from transmit antennas (420).
Abstract:
