摘要:
A method for detecting a fault in a robot joint includes the steps of: performing a first torque measurement at the robot joint to thereby obtain a first set of torque values; calculating a first distribution characteristic reflecting a distribution of the first set of torque values; performing a second torque measurement at the robot joint to thereby obtain a second set of torque values; calculating a second distribution characteristic reflecting a distribution of the second set of torque values; and comparing the first and the second distribution characteristics to determine whether a fault is present or not. A difference in the distributions of torque measurements is a robust fault indicator that makes use of the repetitive behavior of the system.

A user terminal may include an IP Multimedia Subsystem, IMS, client to enable the terminal to communicate with an IMS network. The IMS client may include a conference creation and control unit configured to create and control an IMS conference involving one or more participants, participants being identified within a conference INVITE or REFER message by respective Uniform Resource Identifiers, URIs, within a URI list. The conference creation and control unit may include a response handling unit configured to receive from the IMS network, in response to the sending of an INVITE or REFER, a SIP response message including an XML body specifying an Outgoing Communication Barring, OCB, service invocation result and configured to present the specified result to a terminal user. Related methods and application servers are also discussed.
摘要:
Plant protection device in the form of a weather protection extensible over the cultivation. The protection device including a framework (12) consisting of longitudinal and traverse support elements (13, 14) within which at least one waterproof foldable plant protection curtain (16) is extensible from a folded up position and vice versa. The invention also refers to a foldable curtain as a plant protection for cultivations, which curtain (16) has a high tensile strength in it's longitudinal and traverse directions and which via connectors (29) is hung up on a number of support lines (30) stretched across the curtain. The curtain is extensible from a folded up position to an extended position and vice versa, whereby the curtain includes a framework (18) consisting of strips or ribbons and/or lines. The curtain (16) is made of a waterproof laminate and is including relative to the curtain movable stretch or reinforcing lines (22) in essentially parallel rows stretching along the curtain's length. The curtain is provided with a device which in the extended position of the curtain form channels (36).
摘要:
A method and system are disclosed for more effectively restoring cells in a radio communications network taking into account current traffic conditions. The disclosed method can be implemented in a number of ways. For example, if a network operator desires to prioritize recovery on a cell-by-cell basis, the order of prioritization can be overlaid on the present method (e.g., for all “priority 1” cells, the present method will be used to select a cell recovery order). Alternatively, the present method can be overlaid on an operator's order of prioritization (e.g., for all cells that are classified most urgent according to the present method, the operator's priorities will be used to select the cell recovery order). As another example, if a hierarchical cell structure is used, the underlaid cells can be selected for recovery during the initial recovery operation (e.g., for a speedier recovery). Also, a recovery order sequence can be used to select certain cells from within the group of underlaid cells. The radio network's recovery is thus optimized by taking into account the actual traffic requirements in the network, node and/or cells involved.

A method and system for controlling a vehicle includes receiving vehicle position information from a positioning system and combining the position information with information from a map database and a driver behavior model to control the vehicle's speed and braking for not only the current roadway the vehicle is operating on but also on upcoming road sections.
摘要:
A method and an apparatus for routing traffic in a circuit-switched network, comprising offering a call between between an origin node and a destination node to a preferred route between said nodes, and if said preferred route is not available, offering an alternative route via an intermediate node, and for links between two nodes, setting a first trunk reservation threshold for reserving a certain number of circuits for direct calls along said links between said two nodes, and setting a second trunk reservation threshold for calls between nodes connecting a second link of said alternative route.
