    摘要: A method and system for reducing fault analysis times in a network having a plurality of pollable objects. Poll responses are received from pollable objects, priorities are assigned to each received poll response in accordance with one or more of a received poll response value, a pollable object status and a type of pollable object, and the assigned priorities are processed and to determine any fault locations, wherein a pollable object with a higher priority is processed before a second pollable object with a lower priority. A status manager is operable to receive poll responses from one or more of the pollable objects, a status analyzer is operable to assign, in conjunction with one or more analyzers, priorities to each received poll response in accordance with the received poll response value, a pollable object status and a type of pollable object, and analyzers coupled the status analyzer use the assigned priorities and the corresponding received poll responses to determine a fault location.

    摘要: A nestable container which is constructed so that when formed into a stack the ribs formed in the outer surface of one container rest on an inner shoulder of the container below it in the stack, the angle of inclination of the ribs being the same as the angle of inclination of the inner surface of the side wall portion which it abuts of the container below it in the stack, and the outer surface of one container adjacent to the base engaging the inner surface of the side wall portion of the container below it in the stack to form a powder seal. The cups when nested together to form a stack are freely rotatable one inside the other.

    摘要: A temperature compensating capacitor device is described. The device incorporates at least two capacitors with different dielectric materials which vary with temperature such that the overall capacitance of the device remains substantially constant. Filter circuits incorporating such devices and methods of making them are described. Capacitors of one dielectric material are formed by etching a conductive coating on one face of a layer of that material. The layer is attached via a conductive coating on its other face to the base of a housing, and capacitors of the other dielectric material are attached to its etched face. Other impedances are attached between the capacitors to form the ladder network.

    摘要: According to one or more embodiments, a directional filter assembly (10) comprises a multi-port filter circuit (12) for combining or separating signals in specified pass-bands and an isolated port (20) having a resistive load (22), for absorbing out-of-band signals. The assembly further includes a reflective protection device (24) configured to protect the resistive load (22) from being overpowered by out-of-band signal power, based on being configured to reflect or not reflect the out-of-band signals in dependence on the level of out-of-band signal power. In at least one embodiment, the directional filter assembly is configured as a microwave transmission assembly, such as is used for combining signals from two or more base stations, for transmission from a common antennae assembly.

    摘要: A linear actuator includes a drive arm and an extension arm each extending along a common drive axis. One of the arms has a plurality of resiliently deformable fingers extending beyond the end of the arm towards the other arm. At least one of the fingers has a thread on its inner face while the other arm has a threaded portion. At least part of the threaded portion is received between the fingers. The fingers are adapted to urge the threads of the two arms into interengagement such that rotation of the drive arm about the drive axis displaces the extension arm along the drive axis. The two threads are arranged such that when the ridge of one thread is received in the groove of the other thread the two sides of the ridge abut the two edges of the mouth of the groove.
