Abstract: Improvements to network switches and other network components that enable improved status monitoring and logging of network and device parameters, particularly for networked video surveillance applications. The network switch or other network component, which may be an IP camera for example, outputs a networked video stream which contains graphical representations of relevant data, such as simple graphs or indicators. The networked video stream, and therefore the relevant data, can then be conveniently viewed and/or stored as a networked video stream with existing standard technology. An additional benefit is that conventional motion detection can be performed on the graphical representations in the networked video stream to generate alarms or trigger events.

Abstract: The tissue treatment device consists of a bladder (2), having inlet (1) to be connected to a fluid source (not shown). The bladder (2) is placed within a wound cavity and inflated to conform to the cavity shape and apply constant pressure against the wound surface or pulsed pressure, as required. A seal (3) isolates bladder (2) and the wound cavity from atmosphere. Seal (3) includes one or more inlets/outlets (4, 5) for connection to a vacuum source and/or for the supply of media to be introduced into the wound cavity. The vacuum source can be a vacuum pump or a continuous vacuum provided in hospitals. The media to be introduced into the wound cavity can be saline, water or ozone, oxygen, or any substance to promote wound healing. The bladder (2) is made from polymeric material and can also be impregnated with wound healing compounds to promote healing.

Abstract: A digital closed circuit television system is disclosed enabling high-definition digital video and other information to be transmitted over standard co-axial cable as well as including bi-directional communication. According to one embodiment of the invention there is provided a video monitoring system comprising at least one digital video camera creating a digital video stream wherein the or each digital video camera produces a camera signal, at a particular transmission rate, representing at least the digital video stream for transmission over a co-axial cable infrastructure; an interface enabled to receive the camera signal from the or each digital video camera transmitted over a co-axial cable infrastructure and reconstruct the camera signal back into the digital video stream and send an interface signal to the or each digital video camera; and a storage medium wherein the or each digital video stream received by the interface can be stored.
