Abstract: A differential gear is equipped with a selectively controllable locking device which is self energizing, i.e. it utilizes the differentiation energy to self-lock on its own accord. The control signal is therefore not needed to lock the locking device but rather to selectively, separately for each of the two possible differentiation directions, control it to not lock itself. This gives the differential gear four different working modes. These are: open regardless of differentiation direction; open in one differentiation direction but self-locking in the other direction; open in the other direction but self-locking in the first one; self locking regardless of differentiation direction. A control unit is supplied with sensor data of the present “driving situation”. The control unit has a steering strategy.

Abstract: A system and method for transferring or transporting water from a water source to a consumer can be used and performed while maintaining water quality. Containers housing or transporting the water maintain the water in an essentially liquid state at a low temperature. Consumers are connected to the water supply through taps in a larger system.

Abstract: A nitride glass with the general formula ?x?y?z is provided wherein ? is a glass modifier comprising at least one electropositive element. ? comprises Si, B, Ge, a and/or Al. ? is N or N together with O, whereby the atomic ratio of O:N is in the interval from 65:35 to 0:100.

Abstract: The present invention aims at depth or field improvements or digital cameras, where differently-focused images of a scene, to be photographed, are exposed. A final image is produced from these primary-shots, where depth of field-limitations related to classic photo-lenses, are essentially eliminated. Specific new problems related to camera-viewfinders and camera-focusing are emerging however, due to the increasing number of images being registered. Following the present invention, advantageous procedures regarding camera viewfinders, for visualizing the individual primary shots as well as images processed for improved depth of field, are outlined. A simple technique for upgrading a standard digital camera for depth of field-improvement operation, including an adequate method for preselecting focuses, is illustrated by FIG. 5. These problems and others, related to a photographers adjustments and handling of various kinds of depth of field-enhancing cameras are remedied by applying the present invention.

Abstract: An anti-theft box (100) for protection of goods comprises a main body (110) defining an inner space for the goods to be protected, a lid (120) closing said main body (110), an alarm transmitter triggering a central alarm in case the anti-theft box (100) passes an alarm gate, and a releasable lock (140 145, 150, 160) locking the lid (120) to the main body (110). The anti-theft box according to the invention also comprises an internal alarm circuit (200) that is controlled to be fused when the releasable lock (140 145, 150, 160) is in a locking position and defused when the releasable lock (140 145, 150, 160) is in an unlocked position. The internal alarm circuit (200) comprises a first switch (210), which in the fused state is arranged to trigger the alarm circuit to emit a sound signal in case the first switch (210) indicates that the lid (120) and the main body (110) are separated.

Abstract: A push-pull amplifier having low output impedance and low crossover distortion is provided. A least one of a current through a sourcing current path of an output stage and a current through a sinking current path of the output stage is determinative of a quiescent current control signal produced for controlling a quiescent current of the amplifier. The quiescent current is controlled by symmetrically controlling a bias voltage applied to a sourcing active output device and a bias voltage applied to a sinking active output device in response to the quiescent current control signal. An output stage sourcing control signal for controlling the sourcing active output device is referenced directly to a shared terminal of the sourcing active output device, and an output stage sinking control signal for controlling the sinking active output device is referenced directly to a shared terminal of the sinking active output device.

Abstract: The invention relates to a distributed electronic counter measures solution, wherein jamming signals (JA; JB) may be emitted towards threats (X1, X2) from counter measures stations in multiple vehicles (A, B), which are physically separated from one another in order to improve the chances of survival the vehicles (A, B) as well as any other vehicles that are associated with these vehicles (A, B) in a group of vehicles. The vehicles in the group exchange messages (D) over a wireless data link (L), where the messages (D) sent from a particular station specify an availability status (Dres-status) for each electronic warfare resource in the station and a threat status (Dthr-status) registered by the station. A station in the group having a central planning function coordinates any jamming signals (JA; JB) emitted from the electronic warfare resources of the stations in the group, such that the resources are optimally used with respect to all of any registered threats (X1, X2).

Abstract: A station for assisting the control of an aircraft includes warning means (5) adapted to deliver an alert for avoiding a later collision when there is a risk that the predicted flight trajectory of the aircraft crosses any predicted flight path of another aircraft. An arrangement (4) is adapted to determine whether the aircraft carrying said station is within an airspace volume with defined geometrical dimensions and time of appearance and disappearance or not and make the function of the warning means dependent upon this comparison by, when located in said airspace volume, deactivating said warning means with respect to other aircraft of a predefined identity, and when not located in said airspace volume, activate or keep the function of said warning means activated with respect to aircraft of said predefined identity.
