Patent number: 6906684Abstract: A receiver receives an electromagnetic signal via an antenna mounted on an antenna mast. A signal evaluator determines or measures a signal quality level associated with the received electromagnetic signal. The signal quality compares the determined signal quality level to a threshold minimum signal quality level. A current elevational position of the antenna mast is detected or tracked. The antenna mast is raised to a greater height than the current elevational position if the compared signal quality level is less than the threshold minimum signal quality level and if the current elevational position is less than a maximum height of the antenna mast.Type: GrantFiled: October 30, 2003Date of Patent: June 14, 2005Assignee: Deere & CompanyInventor: Christopher David Glenn Turner

Patent number: 6853353Abstract: An antenna assembly for a wireless communication equipment of the invention comprises a fastening base that is fixedly connected to one side of the wireless communication equipment. An arm, retractable and deployable, has a first end that is movably connected to the fastening base in a manner that the arm, retractable and deployable, is capable of retracting close to the side of the wireless communication equipment and deploying away from the side of the wireless communication equipment. An antenna stem is pivotally connected to a second end of the arm, retractable and deployable. The pivotal connection between the antenna stem and the arm is such that a directional orientation of the antenna stem relative to the axis of the arm is adjustable by rotation for obtaining optimal transmission and reception.Type: GrantFiled: November 12, 2002Date of Patent: February 8, 2005Assignee: Accton Technology CorporationInventors: Chun-Chieh Wang, Shih-Ying Lin

Patent number: 6847331Abstract: A mobile antenna that repeatably can be attached and detached by rotation from motor vehicles. The antenna having a receiving portion electrically connected to a base body having a contact area for connecting to motor vehicles. The joined base body and receiving portion being encased in a jacket. The base body having grooves with flank surfaces also encased in the jacket; the grooves aligned in the lengthwise direction of the antenna so that the groove flank surfaces are essentially perpendicular to forces produced when the jacket is rotated for attachment and detachment of the antenna to or from the motor vehicle.Type: GrantFiled: December 6, 2002Date of Patent: January 25, 2005Assignee: Hirshmann Electronics GmbH & Co. KGInventors: Christian Joly, Tobias Kleinert

Patent number: 6795037Abstract: A radio-frequency antenna for a magnetic resonance system has a basic element with two end rings and a number of antenna rods, and a radio-frequency mirror. The end rings are arranged concentrically relative to an antenna axis can and are axially offset from one another. The antenna rods are arranged around the antenna axis and connect the end rings. The radio-frequency mirror is inductively coupled to the end rings and the antenna rods. It limits a magnetic resonance excitation signal emitted by the antenna and/or a magnetic resonance signal received by the antenna axially at one side.Type: GrantFiled: March 14, 2003Date of Patent: September 21, 2004Assignee: Siemens AktiengesellschaftInventor: Helmut Greim
