Abstract: A data storage system and a method of cooling the data storage system are presented. The data storage system includes: an enclosure; one or more drawer structures disposed within the enclosure, wherein at least one of the drawer structures is configured to receive one or more electronic devices; and one or more temperature control elements positioned adjacent to the bottom of the at least one drawer structure, wherein at least one of the temperature control elements is arranged in use to thermally communicate with at least one of the electronic devices.

Abstract: The invention provides a data storage system and a method of cooling storage media within a data storage system. The data storage system comprises an enclosure; plural drawer structures each containing plural storage media such as disk drives, wherein the storage media are arranged such that air can pass vertically within the system through and between at least 2 of the plural drawers thereby to cool the disk drives in the system by a vertical flow of air within the system; and air flow generating means to generate a vertical flow of air through the drawers.

Abstract: A method of creating a sensor network from a plurality of sensing devices that includes identifying a plurality of subsets of the sensing devices, each of the subsets providing a preferred (e.g., desired or specified) sensing quality coverage. Communication signal strengths of the sensing devices in the subsets are adjusted to seek to enable direct or indirect communication between active sensing devices in all of the plurality of subsets, thereby creating a sensor network.

Abstract: A network monitor that taps data from a network link has first and second interfaces that allow the network monitor to be connected in-line in the network link between two network devices. The monitor has first and second programmable logic devices. The programmable logic devices are arranged to receive parallel data output by the interfaces and to process said data for network analysis purposes. Each programmable logic device is controllable so as to selectively pass a copy of the received parallel data to the other programmable logic device so that the network monitor can operate in in-line mode and not to pass a copy of the received parallel data to the other programmable logic device so that the network monitor can operate in end station mode.
