  • Patent number: 7769568
    Abstract: Initial assumptions related to the service life of a particular item, such as a component section of a building, are mathematically modeled to construct an initial lifecycle condition relationship as condition index (CI) v. time. To update the model, empirical data may be input at any time. As modeled in an engineering management system, for example, inspections are performed on the item to verify actual condition with that predicted. Quantitative inspection data are then used to update the initial curve. As inspections are performed and data recorded, the curve is updated to accurately capture observed condition and provide realistic estimates of predicted condition, and expected service life. In select embodiments of the present invention, empirical data, such as that from inspections, are weighted, e.g., inspection data may be weighted based on type, level of detail, time in service, time since last inspection and the like.

  • Patent number: 7734388
    Abstract: A wheel-speed-sensor-anomaly detection apparatus detects anomaly of wheel speed sensors of a vehicle. When a difference between the minimum wheel speed among detected wheel speeds and the smallest value among the remaining wheel speeds is greater than a predetermined threshold value, in principle, a wheel speed sensor of the wheel corresponding to the minimum wheel speed is determined to be anomalous. Meanwhile, when a wheel having a lowered tire air pressure (air-pressure-lowered wheel) is present and a road surface on which the vehicle is currently traveling is a low-? road surface, the operation of detecting anomaly of the wheel speed sensors is prohibited. This operation reliably prevents erroneous detection of anomaly of the wheel speed sensor of the air-pressure-lowered wheel, which erroneous detection would otherwise occur due to the locking tendency of the air-pressure-lowered wheel occurring because of decreased tire air pressure, in particular, on a low-? road surface.

  • Publication number: 20090326833
    Abstract: An apparatus includes a deformable structure in which a neural network comprising a plurality of deformation sensors, e.g. nanowire sensors, and distributed in-situ processing circuits. The circuits generate a signal characterising features of the local deformation of the structure and/or a command signal corresponding to the detected deformation. The structure may be a wearable sleeve that conforms to deformations of a user's skin, part of an electronic device, such as a touch sensitive screen, or an object in itself. The apparatus can provide a user interface, wherein a command corresponding to a current shape of the structure is generated and acted upon by a integrated or remote device, or a device for monitoring a user's position or movement e.g. for replication by a robotic device. The apparatus may have machine learning capability to improve the matching of commands with determined shapes of the deformable structure.

  • Patent number: 7640066
    Abstract: A method and system is provided for gathering and packetizing data from networked building automation equipment, and for transmitting data packets as instant messages to remotely located users. An instant messaging (IM) server-based system is provided to facilitate communication between networked building equipment and a remotely located service contractor. When a registered router is operated, the router establishes a continuous pass-through communication link with the IM server and with building equipment connected to the router. The router automatically polls connected building equipment for alarms, faults and system failures, and also receives, processes, and responds to user requests for specific data from particular items of building equipment. Data gathered by the router is packetized, and the packets are then encapsulated into an instant message that is transmitted to the IM server.

  • Patent number: 7627452
    Abstract: A device and a method for predicting the mean time period between two failures of a technical system, for example a manufacturing system or an assembly system for motor vehicle components. The device includes a components list (130.1, 130.2). Those components of the technical system which are included in this components list are the maintenance-intensive components. Every failure of a component of the list leads to a failure of the system. Furthermore, the device includes an apparatus for acquiring setpoint MTBF values of all the components of the list. A setpoint MTBF value of a component is a requested or planned mean time period between two failures of this component. The apparatus predicts the planned mean time period between two failures of the technical system as a function of the setpoint MTBF values of the components.

  • Publication number: 20090281734
    Abstract: What is disclosed is a novel system and method for determining real-time performance in a sub-assembly device that is driven by a dc motor. In one example embodiment, an electric motor is energized such that a sub-assembly driven by the motor achieves a target operating speed. Pulse width modulation data is captured and plotted along a time axis. A time duration when the sub-assembly device ended a startup operation and achieved a steady state operation is determined. A portion of the plotted data is then compared to an ideal plot defined for that sub-assembly device. Based on the result of that comparison, a determination is made whether the sub-assembly device is performing within accepted operational parameters. A maintenance operation is signaled to be performed in response to the determined sub-assembly operational performance. The data is stored in a historical database from which a preventative maintenance schedule can be derived.

  • Patent number: 7613585
    Abstract: A system, method and software product for defining material properties hierarchically in a finite element analysis of a structure is disclosed. As a material type is created, the type is checked whether it is a root material type. If so, all of the material properties are defined explicitly in the current definition. Otherwise, the parent material type is searched and located first until the traversing finds a root definition. All of the material properties of the parent material type(s) found are read in and stored as the base properties of the material to be created. The material properties explicitly defined in the current definition of the material will either overwrite or add to the base properties. The material properties definition resembles a hierarchical tree: each of the material properties type has a parent material except the root material type which is on the top of the tree.
