Title: Optical communication network
Inventor: NAGATSU NAOHIDE
IPC: H04J14/02
Filed: 1999-12-06
Abstract: A wavelength division multiplexing ring network is constructed using a simple architecture and a fewer number of hardwares between the nodes compared with the conventional ring network. Each node is structured so that any number of multiple waves can be processed, and a fault in the network or within a node is resolved by providing a path-based protection so that switching can be performed without disrupting other nodes or even within one node. The network uses two or four lines of optical fibers, and a half of the fibers are used for communicating in a clockwise direction and a other half of the fibers are used for communicating in a counter-clockwise direction to form a logical network by optical paths contained in optical fibers so as to provide an equal number of relay nodes between two adjacent pairs of nodes throughout the network, where each node includes: multiple optical add/drop circuits; an optical path transmit end and an optical path receive end for freely selecting and outputting multiple combinations of wavelengths to be inserted in each node; and transmission lines provided between the optical add/drop circuits and the optical path transmit end, as well as between the optical add/drop circuits and the optical path receive end for transmitting any multiple waves to be processed within the node so as to establish mutual communication by transmitting processed multiple waves to other nodes. This network design enables to reduce the number of connections between the optical path transmit and receive ends, and also to reduce the number of optical signal op termination circuits.

Title: Visually symmetric removable low protrusion tensioned sign display system
Inventor: WITTENBERG RON LEO
IPC: G09F15/00
Filed: 1998-06-01
Abstract: A specially engineered, low protrusion, visually symmetric small footprint system of mounting advertising displays to vehicles, such as trucks, tractor trailers, and vans, providing upward/downward adjustability, ease of frame removal and remounting, and over-center tensioning by means of specially designed rails which are attached to the surface of the vehicle. The rails are reversibly fastened to the surface of the vehicle, and can be easily and repeatedly removed and refastened in a short time. This is effected by sinking threaded screw seats into the wall on which the sign frame is mounted, providing permanent holes into which can be repeatedly screwed into and unscrewed from, the low protrusion screws which hold the sign frame to the wall. The hardware residue, after removal of the frame, is barely visible, with a very small footprint, being simply the protruding rims of the threaded screw seats. The entire system, when loaded with signage, and tensioned, protrudes very slightly from the surface of the vehicle, capitalizing on the total width tolerances to within which large trucks and tractor trailers are constructed, and designed not to increase such width beyond applicable regulatory maxima when fully operational. The system is designed to facilitate the mounting of state of the art flexible advertising or publicity media at tensions which practically maintain the signage in a virtual plane, thus enhancing readability and reducing image distortion to the viewer yet do not put such strength demands on the mounting system such as to require a large footprint or permanent complex hardware appendage to the vehicle. Additionally, the parts comprising the anchoring and tensioning rails are only two in number, thus allowing for ease and economy of manufacture, as well as simplifying the inventory and installation processes. Due to the symmetric and streamlined mounting aspects of this system, it also lends itself well to bringing visually sleek and symmetric, removable tensioned small footprint signage to the fixed billboard market.

Title: Low profile heat exchange system and method with reduced water consumption
Inventor: KORENIC BRANISLAV
IPC: F28F27/02
Filed: 2000-03-08
Abstract: A system and method of exchanging heat are disclosed. Three heat exchange sections are used: a dry indirect contact heat exchange section, a second indirect contact heat exchange section that is operable in either a wet or dry mode, and a direct contact heat exchange section. The three sections are next to each other in an apparatus to reduce the overall height of the apparatus. The dry and second indirect contact heat exchange sections receive a process fluid in series or in parallel. Separate ambient air streams pass through the second indirect and direct contact heat exchange sections before mixing and entering the dry indirect contact heat exchange section. Another ambient air stream is mixed in upstream of the dry indirect contact heat exchange section when the system is operated in the dry mode. Two independent evaporative liquid distribution systems are included. One selectively distributes evaporative liquid over the second indirect contact heat exchange section. The other selectively distributes evaporative liquid over the direct contact heat exchange section. Separate sumps, pumps and conduits are provided for the second indirect and direct contact heat exchange sections. The system is operable in different modes to extract heat from the process fluid in the most efficient way with respect to annual water consumption. At low temperatures, the system operates dry with primary heat extraction performed by the dry indirect contact heat exchange section. At higher temperatures, evaporative liquid is distributed over the second indirect contact heat exchange section but not over the direct contact heat exchange section. At still higher temperatures, evaporative liquid is distributed over both the second indirect and direct contact heat exchange sections. A  temperature or pressure sensor may be provided so that operation of the apparatus may be based upon the process fluid temperature or pressure. Alternatively, operation may be based upon ambient air temperature.
