摘要:
Methods and apparatus for monitoring a network and generating overall health scores for communications nodes in the network are described. A monitoring system receives information from a variety of system elements and/or devices which provide information relating to communications service. The information received by the network monitoring system includes information indicating the number of outstanding work orders issued in regard to a trouble report, signal power level variance information, signal alarm information, uncorrectable error information, correctable error information, offline device information, etc. A set of scores for a node are generated based on the different types of received information. The scores are combined using a weighted sum to generate an overall node health score. Nodes are ranked based on overall node health scores and maintenance personal can view the scores as well as the underlying information corresponding to a node to facilitate identification of possible faults.

Disclosed is a steering control system/method for a process line running a web material including at least two steering units, a downstream and an upstream steering unit. At least one controller is in communication with the downstream and upstream steering unit. The downstream steering unit collects downstream data concerning a downstream position of the web material and sends the downstream data to the controller. The upstream steering unit collects upstream data concerning an upstream position of the web material, and sends the upstream data to the controller. The data may be an actual position of the web material or a position of a frame or a roller of the steering unit. The controller utilizes the downstream data to effect a downstream adjustment of the downstream steering unit. The controller utilizes the downstream data and the upstream data to effect an upstream adjustment of the upstream steering unit.

A wireless interface module interfaces a machine control system, such as a vending machine controller, with one of plural wireless networks through one of plural removably coupled wireless transceivers. Communication between geographically distributed vending machines and a desired wireless network is supported by coupling a transceiver associated with the desired network to the wireless interface module. This advantageously provides flexibility in selecting from one of plural wireless networks for a distributed vending machine so that communication between the control system and a distal operating center is supported over a preferred wireless network through a standardized wireless interface module incorporated in the vending machine by changing the wireless transceiver removably coupled to the wireless interface module.

A positional control device is provided to prevent accidental drifting of an overhead sectional door upward or downward from a fully opened, partly opened or fully closed position. The device allows the door to be manually moved to a different elevation without requiring a separate operation to release the door from its original position. This is achieved by a mechanism which couples the upward and downward motion of the door to the rotation of a sprocket wheel engaged with a spring loaded ratchet arm with a bifurcated head specially shaped for ratcheting engagement with the teeth of the sprocket wheel. Suitable adjustment of the spring allows the ratchet mechanism to hold the door in its given position by exerting a force which can readily be overcome by manual raising or lowering the door to a different position.

A walking beam assembly includes a pair of axles in parallel spaced relation. At least one of the pair of axles being a drop axles having end portions and an intermediate portion that extends between the end portions. The intermediate portion drops down and has a secondary axis which is offset from and substantially parallel to a primary axis provided by the end portions. A pair of walking beams extend in parallel spaced relation between the pair of axles. Each walking beam has opposed ends, a central transverse pivot axis intermediate the opposed ends, and a longitudinal pivot axis. The opposed ends of each walking beam are secured via connectors on top of the intermediate portion of the at least one drop axle adjacent one of the end portions. Each of the connectors allow limited pivotal movement about the longitudinal pivot axis of the walking beam.

An electrical transformer box for mounting a low-voltage transformer partitioned into two spaces. A box-like transformer is divided by a partition into two volumes with the first volume being approximately one-half of the second volume. The transformer enclosure is nailed to a wall stud or fixed structure. Household current wires enter and exit into the smaller space. Wires connecting the household current pass through a bore in the partition into the larger space where a low-voltage transformer is mounted for connection to the household current wires. Low-voltage wires pass from the low-voltage transformer to a low-voltage appliance outside of the transformer enclosure.

A tribometer which approximately duplicates the forces exerted on a test surface by a human foot or cane tip during the walking process. The force exerted on the test surface by a test specimen is provided by a fluid actuated cylinder supplied with a compressed fluid. This force is applied during a sufficiently short period of time so as to avoid the absorbtion and squeegee effects normally encountered when testing wet surfaces. The coefficient of friction for the test surface is then determined by measuring the angle of incidence at which the test specimen will slip when brought into contact with the test surface.

An improvement in a Horizontal Pull Slipmeter (HPS) enables more accurate and more rapid coefficient of friction measurements to be made upon walking surfaces. The improvement involves a specialized interaction between a drag sled and a stationary pulling mechanism which in conventional HPS devices, are seperate entities. The specialized interaction utilizes paired tracks which extend from the pulling mechanism and serve to guide the drag sled. The pulling mechanism utilizes a motor which is automatically activated when the HPS is placed on the walking surface and pulls the drag sled at a constant speed.

A mill comprises a shaft mounted in a pair of bearings located at one end of the shaft, and a wall having an opening through which the shaft extends. A horizontal-flow container for the charge is removably mounted at one end in cantilever fashion upon one side of said wall and has a screened outlet at its other end. A tubular inlet housing is mounted on the other side of said wall, surrounding a portion of the shaft between said wall and said bearings, and has a seal through which the shaft enters the inlet housing. A feed screw is mounted on said portion of the shaft. Another portion of the shaft, extending within the container, is of greater diameter than said opening and is closely spaced from said wall to provide a narrow gap through which material passes from the inlet housing into the container. The shaft is hollow and has means for circulating a cooling fluid therethrough, and a shroud holds a cooling fluid in contact with the exterior of said seal.
