Abstract:
A network of processing devices (305, 306, 307) is arranged to communicate by means of packets having an addressing header and a data portion. Within the network, audio telephony is implemented. A signalling packet is sent from a source processing device to a central location (300) identifying a destination processing device. A signalling packet is sent from the central processing location to the destination processing device identifying the source processing device. A packet is supplied from the central location to the sourcing processing device identifying an address for the destination processing device, whereafter packets containing digitized audio signals are transmitted over said network directly between the source processing device and the destination processing device.
Abstract:
A sensing system is configured to detect physical parameters of a fluid sample. In particular, the sensing system is configured to detect the dew point of the fluid by reducing temperature of a sensing medium and detecting the fluid condensate on a sensing surface by directing light from a light source to the sensing surface and detecting the light reflected off the sensing surface onto a light detector. The light source and the light detector are on the opposite side of the sensing medium from the sensing surface.
Abstract:
The present invention is directed to a process for manufacturing a carbonaceous sorbent, particularly activated carbon, that uses lower average residence times and/or higher operating temperatures to produce activated carbon having favorable properties for mercury collection.
