Abstract: A well bore is inspected to detect cement defects that can give rise to leakage. The well bore comprises an inner metal pipe. Outside the inner metal pipe its configuration may vary with distance from the top of the well bore in terms of concentric pipes outside the inner metal pipe and presence of cement between the pipes. A probe with is lowered through the inner metal pipe. An ultrasound signal is transmitted from the probe into the inner metal pipe and responses to the transmitted signal are received at a series of ultrasound receivers at different axial positions. A selection of a spatial frequency of waves arriving along the axial direction at the ultrasound receivers and/or the apparent velocity of said waves is retrieved dependent on the configuration. The received responses are band pass filtered accordingly.

Abstract: A system and method are provided for transmitting data via a network. Upon receiving a request for unicast transmission of the data, the system and method respond to the request by i) formatting the data in accordance with a transport protocol to obtain formatted data and ii) providing the formatted data to the network, the formatted data comprising a destination address field. The network is a programmable network comprising one or more forwarding nodes that are remotely controllable. In order to effect a multicasting of the formatted data, the one or more forwarding nodes are controlled to i) replicating the formatted data to obtain replicated formatted data, and ii) setting the destination address field of the replicated formatted data to an address originating from a further request for the unicast transmission of the data. An advantage of the system and method is that multicasting may be provided for ‘off-the-shelf’ unicast receivers.

Abstract: The invention enables a device to discover one or more other devices within range for a device-to-device mode of communication. This proximity discovery may trigger a target device, e.g. to start listening to signals from a source device or perform any other action based on the proximity discovery like e.g. charging at a toll gate. A source device that wants to be discovered broadcasts a message including an identifier or a representation of the identifier. This identifier may be an identifier of the target device to be contacted or of the source device or a derivation thereof or a common security association used by a set of peers. The target device compares the broadcast identifier with a known identifier to establish proximity discovery.
