Abstract: A flexible layered fabric sheet comprising a porous front layer and a pre-seeded substrate layer, where the seeds are in-between the two layers (rather than at the back of the substrate layer), for supporting root growth, the two layers together having an upper and lower edge and being attached together with one or more non-continuous seams between the upper and lower edges, which seams have a component of direction parallel to the upper and/or lower edge, and wherein the non-continuous seams enable water to exit the layered fabric sheet at its lower edge, and the non-continuous seams further serve to slow water flow through the water sheet. The seams also serve to keep the two layers from separating which would hamper the penetration of the sapling through the front porous layer, and thus stunt growth.

Abstract: 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.

Abstract: According to one aspect of the teachings herein, one or more messages are sent within or from an IP Multimedia Subsystem, IMS, network, to indicate the communication failure of an IMS node supporting a given IMS call session. Advantageously, the one or more messages includes a detection time of the communication failure—e.g., a timestamp—that provides a precision or resolution suitable for adapting a Charging Data Record, CDR, for the affected IMS call session. For example, charges for a portion of the IMS call session are adapted according to the detection time. More broadly, messages indicating the communication failure indication and the corresponding detection time may be exchanged between IMS nodes, e.g., to prompt session termination(s) and/or may be sent to online or offline charging or billing systems, to prevent over-charging.
