Abstract: The present invention relates to a method for managing data output from multiple cameras of a remote tower via a common transmission media to a central entity, non-transitory computer-readable storage medium, and a corresponding remote tower system. The method comprises determining a global GOP sequence for the multiple cameras, determining a first distribution of I-frames within the global GOP sequence and forming a second distribution of I-frames within that global GOP sequence by moving the I-frame of at least one camera. The proposed method allows for transmitting data from a remote virtual tower to a control centre with reduced data peaks whereby the data can be transmitted without additional buffering and the end-to-end transmission delays can be kept at low level.

Abstract: The filter unit has a center frequency and comprises a first dielectric substrate, a first conducting plane, and at least one transmission arrangement. The at least one transmission arrangement comprises a shunt node which has a shunt connection to the conducting plane. The electrical length of the shunt connection defines the center frequency of the filter unit. The transmission arrangement further comprises a plurality of transmission lines connected in series between an input port and an output port, wherein each port is connectable to auxiliary systems with a system impedance. Moreover, each transmission line has a characteristic impedance and wherein the characteristic impedance of each transmission line is less than the system impedance.

Abstract: The present invention concerns an arrangement (1) configured for storing and launching a payload (3) and a method for launching the payload (3) from the arrangement (1). A body (9) of the arrangement (1) comprises a compartment (15) configured to store and eject the payload (3). An aerodynamic surface (11) of the body (9) is provided with a launch opening (13) comprising a guideway (17) extending from the compartment (15). A sliding portion (12) of the payload (3) is configured to slide along the guideway (17) and through the launch opening (13) upon ejection. The extension of the guideway (17) inclines with an acute angle (α) relative the normal (N) to the centre line (CL) of the elongated body (9).

Abstract: The present invention concerns a method for launching a payload (3) by means of an arrangement (1), which is configured for storing and launching a payload (3). A launch compartment (5) of the arrangement (1) is configured to eject the payload (3) from the launch compartment (5) via a push-out chamber (7) to an airflow (AF), which during use of the arrangement (1) flows over an aerodynamic surface (9) of the arrangement (1). An air intake (13) is formed in the aerodynamic surface (9) and is coupled to the push-out chamber (7) and/or launch compartment (5) via an internal air transfer arrangement (17) comprising an openable closure member (11) configured to close and open the internal air transfer arrangement (17).

Abstract: A breech for noise reduction in a recoil-less weapon is described. The breech is adapted to be arranged in fluid communication with a launcher of the weapon to release exhaust gas. The breech comprises a venturi tube. The venturi tube has an inlet at a first end adapted to be connected to the launcher, and an outlet for releasing the exhaust gas at a second end, wherein the area of the outlet is larger than the area of the inlet. The venturi tube further comprises an exhaust gas controlling element formed at the venturi tube structure. The exhaust gas controlling element is arranged to control the release of exhaust gas so as to decrease a sound pressure peak at the weapon. The inner envelope surface of the venturi tube is configured, such that the inner envelope surface does not alter or at least has a very small influence on recoil characteristics of the weapon.

Abstract: A cooling device for providing cooling capability of adjacent structures comprises a hollow chamber, an inlet and a chamber outlet, wherein the inlet, the chamber and the chamber outlet are configured such that fluid flow may enter via the inlet, pass through the chamber, and exit via the chamber outlet. The chamber is divided into a distribution chamber and a cooling chamber by a partitioning member, wherein the inlet is fluidly connected to the distribution chamber and the chamber outlet is fluidly connected to the cooling chamber. The partitioning member comprises at least a first and a second constriction passage, wherein the first constriction passage has a first predefined cross sectional flow area and the second constriction passage has a second predefined cross sectional flow area. The sizes of the predefined at least first and second cross sectional flow areas of the at least first and second constriction passages are controllable, whereby the distribution of fluid flow from the distribution chamber to the cooling chamber via the respective constriction passage is controllable.
