Abstract: An improved active antenna system is distinguished inter alia by the following features: comprising a first antenna group (5) which is provided for transmitting and receiving operation, comprising a second antenna group (10) which is provided for receiving operation, the two antenna groups (5, 10) are arranged above one another, and the supply network (N11, N12) of the first antenna group (5) has an amplitude distribution which is frequency-dependent, i.e. dependent on a transmitting and a receiving frequency.

Abstract: A method and a system for controlling the relative position between a printed pattern and a non-printed pattern, such as for example a pattern of creasing lines or holes, on a running web-shaped material, involves providing the material web with at least one impressed indentation mark with a three-dimensional topographic configuration, at a pre-determined distance from a printed register mark and detecting the marks with a same sensor control system. The controlling method and system is used for the manufacturing of a laminated packaging material, having a printed décor and creased folding lines in register.

Abstract: A pneumatic vane motor includes a stator with a cylinder, an inlet connectable to a pressure air source and an outlet connectable to an exhaust passage, a rotor journalled in the stator, and an output shaft. The stator has a front opening forming a clearance seal relative to the output shaft and an annular front cover with at least one elastic annular seal element encircling the output shaft at a distance from the clearance seal, wherein a low pressure chamber is formed between the clearance seal and the seal element or elements and communicates with the exhaust passage.

Abstract: A data communication scheduling system (300) of a radio base station (100) serving multiple cells (10-30) comprises multiple radio equipment, REs, (101-103) and antenna interfaces (115, 125, 135) connectable to antennas (110, 120, 130). In order to reduce the power consumption, only a subset of the RE (101) is active, while the other REs (102, 103) are turned off. A transmitter controller (155) is arranged for controlling the active RE (101) to be shared among multiple cells (10-30) during a radio frame (40) so that each cell (10-30) is guaranteed at least one sub frame (50-58) for downlink transmission. A receiver antenna system multiplexer(140) selectively interconnects the active RE (101) with the antenna interfaces (115, 125, 135) according to the operation of a receiver controller (145).

Abstract: A PC containing a softphone is connected to a headset (14) by means of a control unit (9) which is connected to a USB gate (6) in the PC. The PC has a security function, which means that the PC can be accessed only by users who e.g. know an access code. The control unit (9), comprising inter alia a sound card, is equipped such that also commands may be given to the softphone (15), even if for security reasons the PC is blocked e.g. by a security code, it being possible to transfer a limited number of commands via the USB gate (6) from the control unit (9). The invention ensures that, irrespective of the state of the PC, the softphone can always be used, as the control unit (9) always gives access to it, which may be important, e.g. in connection with an emergency call.

Abstract: The method is for dynamically authenticating and authorizing a user. A request signal (104) is received from a user into a service unit (97). The service unit extracts identification information (101) from the request signal. The service unit evaluates the identification information and identifies potential users (X, Y, Z). The service unit assigns a probability value (Px, Py, Pz) to each identified potential user (X, Y, Z) to indicate a likelihood of correct identification of the potential users (X, Y, Z). The service unit provides rules sets (RSx, RSy, RSz) for the users (X, Y, Z). The probability requirements (PrRx, PrRy, PrRz) of each rule in the rules sets (RSx, RSy, RSz) are evaluated. The rules are applied for each (PrRx, PrRy, PrRz) less than or equal to (Px, Py, Pz).

Abstract: An add/drop node of an optical WDN-network which has two fiber paths for light of a plurality of channels propagating in opposite directions comprises two add/drop modules (231, 23r) for each of the channels. All the modules are identically constructed. Each module comprises an add device (251, 25r) for adding light to one of the paths and a drop device (27r, 271) for deflecting a portion of light from a second one of the paths. A module comprises a house (41) enclosing the add device and the drop device. A first fixed connector (53, 73) is attached to the house for connection in the first path and to a an optical fiber (45, 65) which extends freely from the house and has a first free connector (43, 63) at its free end to be attached to the fixed connector of a neighboring add/drop module for continuing the first path through the considered add/drop module to the neighboring module.

Abstract: An add/drop node used in an optical network having two fiber paths for carrying light corresponding to a plurality of channels in opposite directions may include a pair of add/drop modules that correspond to one of the plurality of channels. This arrangement advantageously provides a simple approach for connecting the components of an add/drop node.

Abstract: The present invention provides an earmuff device comprising an earmuff cup having at least a window portion which is formed of an optical material which transmits light rays in such a way that the human eye can see through the material to a degree that an earplug or other object inserted within the ear is visually perceivable to the human eye. In other words, the earmuff cup is formed of a transparent material or a translucent material so long as the earplug inserted within the wearer's ear is visually perceivable through the translucent portion of the earmuff cup. Because the earmuff cup is formed of a material that permits an individual, such as a supervisor or hearing conservationist, to perceive whether an earplug is inserted within the wearer's ear, the earmuff device of the present invention is particularly well suited for use in a dual hearing protection environment in which the previous method of compliance monitoring was time consuming and difficult.
