Abstract: A desk includes a top defining a working surface, at least one pair of opposed supporting legs supporting the top above a floor, and a swinging footrest assembly pivotally connected to at least one of the supporting legs. The swinging footrest assembly is selectively removable from the desk and can be selectively positioned at a plurality of vertical positions with respect to the floor.

Abstract: A stand for an electronic device includes a front plate having a channel at a bottom edge thereof for accepting an edge of an electronic device therein, a back plate hingedly connected to the front plate, and a pair of arms extending from opposed sides of the front plate. The arms are adjustable so as to vary a distance between distal ends of the arms to accommodate the electronic device therebetween.

Abstract: A combline filter has a ceramic resonator disposed inside at least one cavity wall. Because the resonator is implemented as a hollow rod, a tuning element may be inserted into an opening on the top of the rod to tune its frequency. A mounting element, inserted into an opening on the bottom of the rod secures its position inside a cavity resonator. Instead of soldering the resonator to the filter's walls, the resonator is supported above a bottom or side wall of the cavity resonator.

Abstract: A triple-mode filter is disclosed, the triple-mode filter including a cavity for confining electromagnetic waves and a metallic block acting as a resonator within that cavity. The metallic block does not contact the conductive walls of the cavity, but is instead suspended by a support element. Triple-mode resonators may be combined to produce bandpass filters having three or more poles. In other configurations, triple-mode cavity metallic resonators may be coupled to triple-mode cavity ceramic resonators or to combline resonators to achieve various filtering functions and performances suitable for different applications.

Abstract: A telecommunications network is provided. The network includes at least one service delivery unit having a data port and a network interface port and a memory that stores data for managing the telecommunications network. The network interface port is coupled to a switch fabric. The data port is coupleable to at least one local area network. A network management station is communicatively coupled to the service delivery unit. The at least one service delivery unit is configurable to allow the network management station to view selected portions of the data in the memory of the at least one service delivery unit to facilitate management of selected aspects of the service delivery unit.
