Abstract: A body-mountable image capture device comprising a device body and a cover slidably mounted onto the device body, the device body comprising a camera, the cover sliding between a first position and a second position such that in the first position the camera is concealed and in the second position the camera is exposed. The body-mountable image capture device comprises activation means operable to initiate the camera when the cover is in the second position and the camera is exposed. The orientation of the camera is adjustable with respect to that of the device body such that the orientation of the camera can be maintained. The orientation of the camera may be automatically adjusted to keep the field of view generally horizontal. The camera may automatically rotate left and right in a horizontal plane responsive to movement of a head mounted sensor to thereby track a user's head movements.

Abstract: A network management apparatus and method processes network management data received during the monitoring of a network and generates events for presentation in an event list to a user when certain event conditions are detected. Network management data received in relation to an event condition is processed to determine whether it represents a recurring event condition. A recurring event condition is determined if a predetermined number of equivalent events have been generated, and appear in the event list, in an immediately preceding time period. In the described embodiment, if a recurring event condition occurs, a recurring event is generated, and subsequent occurrences of the event condition are not included in the event list presented to the user.

Abstract: A network management apparatus and method for determining the topology of a network in which a Spanning-Tree protocol is implemented, is disclosed in which address table data is obtained from the ports of the core network devices on the network, and the identity of the ports of the core network devices are determined. Spanning-Tree protocol information is obtained from the core network devices and used to process the address table data to remove data relating to ports having links which are inactive. The topology of the network is then determined using the processed data by first selecting one of the core network devices as a root network device, and then using the processed address table data to build a network tree from the selected root device.

Abstract: A network management apparatus and method reduces the number of events presented in an event list to a user. In particular, the apparatus and method reduces the number of events, which are generated during the monitoring of a network and may be due to rebooting of a device on the network, presented to the user by determining, upon receiving an event relating to a device, whether a more significant event already appears in the event list relating to the device, and if so, preventing the received event from being presented in the event list to the user.

Abstract: A network management apparatus and method processes network management data in a network management system during the monitoring of a network. The apparatus and method considers whether the network management data indicates that the network condition of an event previously generated by the network management system is no longer present on the network, and therefore resolved. In a preferred embodiment, if the network management data indicates that a previous event has been resolved, the event is marked as resolved for presentation in an event list to the user. The user can then easily identify events which have been resolved.

Abstract: In a network of managed devices, a method of processing network events to reduce the number of events to be displayed in an event log, comprising receiving information relating to network events, passing information regarding a network event to an event processor, determining if the information passed to the event processor relates to a type of event processed by that event processor, and if it is of such a type, processing said information if information on a related event has already been received by that event processor. The method also includes passing said information on to a further event processor if the information received does not relate to a type of event processed by said first event processor.
