Abstract: The invention relates to a method of controlling railroad train movement over a layout of railroad track that is defined geographically using a linear network of geographic control objects which includes signals, switches and track blocks.  Each signal has signal control hardware and software logic, which logic includes an address, representation of signal condition, and the ability to initiate a change in signal condition.  Each switch has switch control hardware and software logic, which logic includes an address, representation of switch condition, and the ability to initiate a change in switch condition.  Each track block has hardware and software logic, which logic includes an address and a representation of track block occupancy condition.  The method is specifically directed to establishing communication between each signal logic, switch logic, and track logic, and only its next adjacent logic neighbors regardless of whether it be signal logic, switch logic, or track logic.  Such communication is limited to one of a plurality of predetermined messages, which messages either request a response relating to train movement or provide a response relating to train movement.

Title: Multiple access coding using bent sequences for mobile radio communications
Inventor: BOTTOMLEY GREGORY E
IPC: H04B1/707
Filed: 1995-08-11
Granted: 2009-10-20
Abstract: Information symbols spread using orthogonal or bi--orthogonal codewords are assigned a unique scramble mask that is taken from a set of scramble masks having selected correlation properties. The set of scramble masks is selected such that the correlation between the modulo-2 sum of two scramble masks with any codeword in a constant magnitude, independent of the codeword and the individual masks being compared. In one embodiment, when any two masks are summed using modulo-2 arithmetic, the Walsh transformation of that sum results in a maximally flat Walsh spectrum. For cellular radio telephone systems using subtractive CDMA demodulation techniques, a two-tier ciphering system ensures security at the cellular system level by using a pseudorandomly generated code key to select one of the scramble masks common to all of the mobile stations in a particular cell. Also, privacy at the individual mobile subscriber level is ensured by using a pseudorandomly generated ciphering key to encipher individual information signals before the scrambling operation.

Abstract: Disclosed is a network system for connecting a plurality of node devices by a plurality of parallel transmission channels and connecting terminals to respective ones of the plurality of transmission channels via the node devices. Each node device temporarily stores output packets by allotting the packets to a plurality of storage areas that correspond to respective ones of the plurality of transmission channels. When a stored packet is transmitted by selecting any one of the plurality of transmission channels, control is performed so as to read out the packet that has been stored in the storage area that corresponds to the selected transmission channel. In a case where a stored packet to be transmitted over the plurality of transmission channels is a packet for broadcast, the packet is duplicated by being distributed to the plurality of storage areas that correspond to the plurality of transmission channels that are to transmit the packet.

Abstract: A package for a semiconductor power device which comprises: a conductive bottom plate as a heat sink; an insulating substrate mounted on the bottom plate; a copper film formed on the insulating substrate to expose a peripheral region of the insulating substrate; semiconductor chips disposed on the copper film; a container arranged on the bottom plate, surrounding the insulating substrate; an external terminal supported through the container and connected electrically with the semiconductor chips; and a silicone gel filled within the container, wherein a solidified insulating material is disposed on an outer edge region of the copper film and the peripheral region of the insulating substrate. Thus, reducing an electric field across the interface and making it difficult to cause a creeping discharge. A notch is formed in the bottom plate, and the notch is filled with a high heat conductive resin. The notch is located outwardly apart from a region where the semiconductor chips are mounted. Thus, a creeping breakdown is prevented without sacrificing a heat radiation effect of the bottom plate. Using a waterproof and flexible film to seal an inlet for filling the silicone gel into the case, a heat stress caused by an expansionand a shrinkage of the silicone gel in response to a variation of temperatures is reduced, and it prevents the silicone gel from being wet. A thermoplastic insulating resin is employed instead of the silicone gel.

Abstract: The present invention relates to a process for the one-stage resalting and purification of oligopeptides. Oligopeptides are often not formed directly as acetates when synthesised.  Acetate salts of oligopeptides are however desirable as bulk-active material for medical and formulation reasons.  Processes known from the prior art have hitherto involved two separate steps or pyridine-containing solvents.     According to the invention the resalting and purification can be combined in one step or the use of pyridine as solvent can be avoided, if the oligopeptide in the form of its chloride salt is purified with an acetate-containing solvent by liquid chromatography methods.
