Abstract: An arrangement includes a plurality of wireless microsystems and a central data processor. Each microsystem is operable to measure a plurality of indoor environmental quality-related parameters and is operable to communicate first information pertaining to the measured parameters wirelessly to a network device. The central data processor is operably coupled to receive the first information from the network device, and further configured to generate a metric value of an indoor environmental quality of at least a first space based at least in part on the first information, the metric value dependent upon each of the measured parameters of at least a first of the plurality of microsystems.

Abstract: A network tool is provided for use when replacing devices in an automatically controlled distributed processing system. The network tool reestablishes all or a portion of the logical connections formerly provided to the node where the replacement device is or will be located. The tool compares data associated with the logical connections of the node and data associated with the logical connections for the replacement device to determine proper logical connection. In one embodiment, the compared data comprises network variables and configuration properties.

Abstract: An arrangement for use in an occupancy-based ventilation system includes a plurality of CO2 sensors and a processing circuit. The plurality of CO2 sensors are disbursed throughout a plurality of spaces in a building. The processing circuit is operably coupled to receive information representative of CO2 measurements generated by the plurality of CO2 sensors. The processing circuit is operable to determine a value corresponding to occupancy, based on information from the CO2 sensors, and to control the flow of fresh supply air into the building ventilation system based on the determined value.

Abstract: A wireless automation device monitors a condition and wirelessly reports an event over an automation network in response to detecting a change in the condition. The condition is sampled at a variable periodic interval, and the event reported during intervals when a change in the condition is determined. The change may be determined according to detecting a value for the condition outside a variable range. The change may also be determined according to detecting differences in the value from values detected in prior intervals. The range and the periodic interval may vary according to an analysis of multiple samples of the condition.

Abstract: The present invention concerns a parallel multiprocessor-multidisk storage server which offers low delays and high throughputs when accessing and processing one-dimensional and multi-dimensional file data such as pixmap images, text, sound or graphics. The invented parallel multiprocessor-multidisk storage server may be used as a server offering its services to computer, to client stations residing on a network or to a parallel host system to which it is connected. The parallel storage server comprises (a) a server interface processor interfacing the storage system with a host computer, with a network or with a parallel computing system; (b) an array of disk nodes, each disk node being composed by one processor electrically connected to at least one disk and (c) an interconnection network for connecting the server interface processor with the array of disk nodes.
