A monitor including a monitor main body to display a picture thereon, and a base member to support the monitor main body. The monitor includes a link member having upper and lower ends rotatably combined to a main hinge provided in the monitor main body and a base hinge provided in the base member, respectively. The monitor also includes an auxiliary link member to connect the main and base hinges, and disposed in parallel with the link member, being eccentric with the monitor hinge and the base hinge, a main bracket interposed between the monitor main body and the link member, and a pivot part to pivot the monitor main body upon the main bracket. Accordingly, the present invention provides a monitor in which a monitor main body is controlled in tilt, planar rotation, and height, thus, maintaining tilt regardless of the height control.

Monitor improved in a tilting structure

A stand for a display having a base, a supporting case mounted on the base, a supporting member mounted inside the supporting case and having an end seated on the base to support the weight of the display, and a mounting bracket engaged with the the other end of the supporting member, to mount the display. This stand supports the weight of a large-sized display and allows a user to swivel the display around an axis of the supporting member, and change the distance between the base and the display.

Stand for display

A monitor having a monitor body and a base member supporting the monitor body includes a link member positioned between the monitor body and the base member, a base hinge connecting one end of the link member with the base member in a tiltable manner to control the link member to be tilted relative to the base member within a predetermined degree of angle, a monitor hinge connecting the other end of the link member with the monitor body in the tiltable manner, an assistant link member transmitting a tilting movement of the link member relative to the base member to the monitor body, a first torsion coil spring elastically biasing the base member and the link member in opposite directions when the link member is forwardly tilted relative to the base member, and a second torsion coil spring elastically biasing the link member and the monitor in opposite directions when the monitor body is forwardly tilted relative to the link member. With this configuration, a monitor body can be easily adjusted in its height and viewing angle. Especially in a case of the monitor having a large-sized monitor body, the height and viewing angle thereof can be easily adjusted, and the viewing angle of the monitor body originally set up can be maintained when the height of the monitor body is adjusted. Also, a tilting angle of the monitor body can be adjusted relative to the base member.

The present invention relates to a method and an arrangement for guiding a missile. In accordance with the prior art, the angle position of a target (9) when the missile (3) is expected to reach the target is predicted on the basis of the angular velocity determined in a preceding time period. In order to improve the strike accuracy, the operator, in a second subsequent time period, tracks the actual position of the missile in relation to the predicted angle position of the target. If a deviation is observed, a correction command is transmitted to the missile in order to correct the missile trajectory. For this purpose, a communications link is provided to transmit the correction command given by the operator.

A system for determining the distance between a target (4) and a laser guided weapon traveling towards the target (4). The system (1) comprises a laser designator (5) on a remote platform (2) for radiating a first train of pulses (l1) on a set wavelength in the direction of the target (4). In the weapon (3) a receiver (6) is arranged to receive and detect pulses on the set wavelength reflected from the target (4). There is also a direction sensing means in the weapon (3) for determining the direction of the target (4). A transmitter (7) is arranged in the weapon (3) to periodically transmit a second train of pulses (l2) on the set wavelength in the direction of the target (4). There are means in the receiver (6) to extract a reflection from the target (4) of the second train of pulses (l2). There are further timing means to determine the period of time from transmitting the second train of pulses (l2) to receiving the reflection from the target (4) of the second train of pulses (l2). Computing means (8) are arranged for determining a distance corresponding to said period of time.

The present invention relates in general to a recoilless weapon (1) and, in particular to a new high-and low pressure system for recoilless weapons (1). The invention provides a recoilless weapon (1) comprising a launch tube (2) open at muzzle (3) and breech (4) ends thereof, a projectile (5) and a counter mass (6) residing in said recoilless weapon (1), the recoilless weapon (1) further comprises a high pressure part (7) containing a propellant charge (8) for propelling the projectile (5) and the counter mass (6) out of the launch system (1), a low pressure part (9) containing the counter mass (6), a blocking element (16) in the rear part of the launch tube (2) and gas- openings (10) between the high pressure part (7) and the low pressure part (9) The invention is characterized in that the projectile (5) is positioned in a first start position, where the projectile (5) is blocking the gas-openings (10) and where the projectile (5), upon ignition of the propellant charge (8), moves to further positions (12') in the launch tube (2), where the gas-openings, successively, are unblocked by the projectile (5).

New inner-ballistic for recoilless weapon

The present invention relates to a method and a device by means of which it has been made possible, without gas discharge to the surrounding environment, to accelerate the speed of a powder-gas-driven projectile from zero to a speed which gives the projectile free-flying characteristics. According to the invention, this has been made possible by utilizing at least some of the expansion force from the propellant powder charge, which discharges gas when it is initiated, for, by a displaceable piston, driving a countermass out of the rear part of the projectile in the direction opposite to the desired flying direction of the projectile.
