The present application relates to a mounting device configured for mounting a base station antenna (10) on a supporting member (11), and providing the adjustability of the mechanical tilt angle of the base station antenna. The mounting device comprises a first mounting unit, a second mounting unit, and an elastic element (3). The first mounting unit is configured to provide a pivot point for the base station antenna, the second mounting unit has an adjustable effective connection length for the base station antenna, with the effective connection length related to the mechanical tilt angle of the base station antenna, and the elastic element is configured to resist an increase in the mechanical tilt angle of the base station antenna on at least a part of the adjustable range of the mechanical tilt angle of the base station antenna. The mounting device allows for the easy adjustment of the mechanical tilt angle of the base station antenna, reducing the workload and safety risks of the operator.

A remotely controllable antenna mount for use with a wireless telecommunication antenna provides both mechanical azimuth and mechanical tilt adjustment using AISG compatible motor control units and AISG control and monitoring systems to remotely adjust the physical orientation of the antenna. The mount control units are serially interconnected with existing AISG antenna control units (ACU's) which adjust internal electronic tilt of the antenna. The present solution provides the ability to both physically aim the antenna to adjust coverage area and also adjust the signal phase to fine tune the quality of the signal.

Provided is a mobile radiography apparatus capable of performing relatively stable wireless communication even in a case in which the mobile radiography apparatus is moved due to traveling of a carriage or an arm is rotated.

A mobile radiography apparatus includes a radiation source, a radiation image detector that detects a radiation image of a subject by receiving radiation emitted from the radiation source and transmitted through the subject, an arm that holds the radiation source and the radiation image detector, a body part to which the arm is rotatably attached, a carriage on which the body part is mounted, and an antenna that emits a radio wave for wirelessly communicating with an external apparatus, the antenna being provided in a portion in which a radiation direction of the radio wave is not changed even in a case in which the arm is rotated and capable of changing the radiation direction of the radio wave.

An antenna device and an orientation adjustment mechanism are provided. The orientation adjustment mechanism includes a holder, a rotation carrier assembled to the holder, and a torsion spring. The rotation carrier is counterclockwise rotatable from an initial position by a first predetermined angle or is clockwise rotatable from the initial position by a second predetermined angle. The torsion spring has an elastic portion disposed on the holder and two extending arms that extend from the elastic portion. When the rotation carrier is rotated from the initial position by the first predetermined angle or the second predetermined angle, the rotation carrier presses and moves one of the two extending arms, and another one of the two extending arms abuts against the limiting portion, so that the elastic portion is deformed to store an elastic force that tends to move the rotation carrier toward the initial position.

Methods, systems, and devices are described for an antenna positioning apparatus, which includes a multiple-assembly positioner for adjusting a positioning angle about a positioning axis. The multiple-assembly positioner has two or more positioning assemblies that are coupled in series between a base structure and a positioning structure. Positioning assemblies can be individually selected based on various criteria, such as cost, complexity, angular range, and other performance, and be configured to work together to provide a desired range of adjustment to the positioning angle while simultaneously meeting precision requirements. In one example, a positioning assembly can include a shaft with an eccentric portion, which is rotated in order to provide the adjustment. A method is described where a first positioning assembly can be actuated to a first initial position, and then held, such that a second positioning assembly can be actuated to provide a selected antenna positioning angle.
