  • Patent number: 6980782
    Abstract: An antenna device for transmitting and receiving radio frequency waves, installable in a communication device includes an antenna structure switchable between antenna configuration states. Each state is distinguished by a set of radiation parameters, such as resonance frequency, input impedance, bandwidth, radiation pattern, gain, polarization, and near-field pattern. A switching device selectively switches the structure between the states. The antenna device includes a first receiver which receives a first measured operation parameter indicative of quality of transmission of radio frequency waves by the antenna structure, and a second receiver which receives a second measured operation parameter indicative of quality of reception of radio frequency waves by the structure.

  • Patent number: 6917790
    Abstract: An antenna device for transmitting and receiving electromagnetic waves, wherein the antenna device includes a transmitter section and a receiver section. The receiver section includes a receiving antenna structure selectively switchable between a plurality of configuration states. The antenna structure may be switched by a switching device, which is controlled by a control device. The selective switching is effected based upon a first measure representing a reflection coefficient measured at the transmitter section. A method for transmitting and receiving electromagnetic waves includes receiving a measure representing a reflection coefficient and controlling a switching device to selectively switch an antenna structure between a plurality of antenna configuration states in response to the measure representing the reflection coefficient.

  • Patent number: 5302050
    Abstract: A device for bridging expansion joints in bridges or the like is provided with parallel lamellae arranged at right angles to the longitudinal axis of the traffic route. The lamellae are supported on at least two inclined traverses which are pivoted and movably supported at both sides in the joint edges, which bridge said joint diagonally with respect to the longitudinal axis, and are rotatably and movably guided in sliding drag bearings at the bottoms of the lamellae. The inclined traverses are arranged parallel to each other, whereby the support width of the lamellae is always uniform. At least one longitudinal traverse which is movably connected the longitudinal direction with each lamellae via sliding bearings fixed at the bottoms of the lamellae is provided for, preferably at the edge, for taking up the forces which inevitably occur due to movements of the bridge superstructure.
