    摘要： 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 neighbouring add/drop module for continuing the first path through the considered add/drop module to the neighbouring module. In the same way a second fixed connector is attached to the house for connection in the second path and to a second optical fiber which extends freely from the house and has a second free connector at its free end to be attached to the fixed second connector of a neighbouring add/drop module for continuing the second path through the considered add/drop module to the neighbouring module.

    摘要： 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). Consequently, the RE (101) becomes connected to different antenna interfaces (115, 125, 135) during different sub frames (50-58) to thereby allow each cell (10-30) at least one assigned uplink sub frame (53-55) in the radio frame (40) at a predefined sub frame distance after the at least one downlink sub frame (50-52) assigned to the same cell (10-30).

    摘要： 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.

    摘要： 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.
