Abstract: In a cryptosystem, communication terminals and encryptors can be grouped physically and logically.  The communication mode can be switched by the encryptor between ciphertext communication and plaintext communication.  The encryptor includes the session key memorizing unit for memorizing the session key and the mode switch for switching the communication mode between ciphertext communication and plaintext communication. The key manager distributes the session key generated by the session key generating unit and the valid/invalid information set by the valid/invalid setting unit to each encryptor.  The valid/invalid judging unit judges whether the communication data should be sent in ciphertext or plaintext using the mode switch and the valid/invalid              . information.

Title: Fuel cells-based generator system and method of the same
Inventor: KAWATSU SHIGEYUKI
IPC: H01M8/06
Filed: 1997-05-22
Granted: 2000-05-16
Abstract: The present invention provides a fuel cells-based generator system that prevents a catalyst in fuel cells from being poisoned and a potential on oxygen electrodes of the fuel cells from lowering, while improving the energy efficiency.  While I2 is fed from a halogen tank 41 to a preliminary reaction tank 30 via a first conduit 33, H2O is fed from a water tank 43 to the preliminary reaction tank 30 via a second conduit 34.  The preliminary reaction tank 30 is heated by the heat transmitted from a stack of fuel cells FC, and the reaction expressed as H2O + I2 ~ 2HI + (1/2)O2 occurs in the preliminary reaction tank 30.  HI produced by the above reaction is dissolved in excess H2O and fed into a reaction tank 50 via a fourth conduit 36.          The reaction tank 50 is heated by the heat transmitted from the stack of fuel cells FC, and the reaction expressed as 2HI ~          H2 + I2 occurs in the reaction tank 50.  The gaseous mixture of H2 and I2 is flown into a hydrogen purifier 60 via a sixth conduit 54.   The hydrogen purifier 60 separates  gaseous hydrogen H2 from the gaseous mixture.  The gaseous hydrogen H2 is then fed into flows paths of gaseous hydrogen in the stack of fuel cells FC.

Title: Heat recovery system and heat exchanger therefor
Inventor: DERKSEN WILLIAM E
IPC: F02N19/10
Filed: 1997-07-04
Granted: 2000-06-27
Abstract: A heat exchanger for use in warming the engine and passenger compartment of a vehicle during cold weather comprises a fluid retaining main body member having a first end, a second end, a main longitudinal axis extending from the first end to the second end, and a substantially hollow interior.  An inlet and an outlet are mounted on the main body member in fluid communication with the substantially hollow interior adjacent the first end and second end respectively.  An exhaust flow passageway having an inlet end and an outlet end in fluid communication one with the other, for in-line connection with a vehicle exhaust system, is mounted in the main body member in throughpassing relation such that the hollow interior of  the main body member  substantially surrounds  the exhaust flow passageway in heat transfer relation.  In use, a heat transfer fluid ingresses the main body member through the inlet, flows from the first end to the second end of the main body portion through the hollow interior whereat heat from the exhaust flow passageway is absorbed, and egresses through the outlet. The heat exchanger is used in a heat recovery system such that the inlet is connected in fluid communication to a coolant outlet of the engine so as to receive liquid coolant therefrom,  and the outlet is connected in fluid communication to a coolant inlet of a heater within the vehicle, so as to supply heated liquid coolant to the heater, and ultimately back to the engine.

Abstract: L'invention concerne un procédé pour la liquéfaction ou bien la gélification d'un noyau de cristallin cataracté (42), et pour l'aspiration dudit noyau. On infiltre in vivo une solution chaude ou réchauffée (30) qui, au contact avec le noyau de cristallin (42) durci chauffe et liquéfie ce noyau. Ledit noyau (42) est irrigué simultanément par une solution refroidie (34), en vue de réduire à une zone très peu étendue l'emplacement qu'occupe la première solution dans l'oeil (40). Ainsi, le chirurgien détermine avec précision les structures des segments antérieurs intra-oculaires exposées à l'action de la solution chaude ou réchauffée (30). Ensuite, le noyau de cristallin liquéfié  est extrait de l'oeil par aspiration (22, 36, 37). Le procédé susmentionné  permet d'extraire un noyau de cristallin à travers une incision du limbe scléro-cornéen mesurant entre un et deux millimètres (46), soit une dimension inférieure à celle des petites incisions pratiquées antérieurement pour la cataracte. Pour le patient, une extraction par petite incision n'a aucun effet traumatique sur les structures intra-oculaires. L'avantage pour le chirurgien, mais aussi pour le patient, est que l'intervention suppose une manipulation relativement simple et facile à exécuter. Il s'agit d'un net progrès par rapport à la technique actuelle de phacoémulsification qui, elle, peut avoir des effets très traumatiques sur les structures intra-oculaires et suppose une manipulation relativement difficile à effectuer.

Title: Method and arrangement for electromagnetic wave distance measurement by pulse transit time method
Inventor: PERDUE KENNETH L
IPC: G01S7/285
Filed: 1998-05-01
Granted: 2001-08-21
Abstract: For  electromagnetic wave distance measurement  by the  pulse transit time method short electromagnetic transmission pulses are  emitted  at periodic transmission  instants.  The  signals received in selected transmission cycles after the respective transmission instants are sampled for obtaining in each of these transmission cycles a sample at a sampling instant in a respective  sampling  time  interval,  each  sampling  instant having a delay dictated by a sampling function relative to the respective transmission instant. The sampling instants exhibit differing  delays  relative  to  the  respective  transmission instant so that the samples in sequence produce an image of the sampled received signal extended in time. The sampling function dictating the  delays  is  generated  by  a  computing  circuit, preferably a microcomputer, thus making it possible to make use of any sampling function and to modify sampling of the received signals  in  any way.  More  particularly,  it  is  possible  to measure the applied delays and to correct them to maintain predetermined design values. One sampling function which can be put to use to advantage in this method is a staircase function, each step of which has the length of several sampling time intervals.

Abstract: A method of altering a portion of the semiconductive layer of an electric power cable, to increase its resistance so as to render it electrically insulative. The semiconductive layer is loaded with carbon powder which form s chains to provide conductive pathways through the layer. By introducing an intercalant into the semiconductive layer, which causes the layer to swell, the conductive pathways are interrupted and the material is rendered insulative ( > 104 .OMEGA.-cm). The intercalant may be a polymerizable material with a curing agent which is cured in situ, i.e., without removing the semiconductive layer from the cable. By this method, flashover to the semiconductive layer at a cable splice or termination may be prevented witho ut requiring tedious removal of the exposed portion of the semiconductive layer . The method is usable with both strippable and coextruded semiconductive laye rs.

Granted: 2004-06-22
Abstract: A method for measuring the attenuation in digital transmission lines between a switching centre and a subscriber station, with a first pulse of a known frequency spectrum being sent from the switching centre to the transmission line. From the multitude of the reflections received by the switching centre in the time domain that pulse is selected which was caused by the total reflection at the end of the line of a certain subscriber station. The frequency spectrum of the selected pulse is determined and from the frequency spectra of the outgoing pulse and the selected received pulse, the attenuation of the transmission line is determined, depending on its frequency. To achieve the extremely high dynamics necessary for this and to obtain a pulse which is free of any overshoot, reflection measuring is carried out selectively in the frequency range and the pulse is calculated per Fourier transformation. In order to reduce pulse widening by dispersion, the pulse in the frequency range is shifted to higher frequencies. The method makes it possible to qualify subscriber stations for new services by measuring the attenuation from the switching centre.
