Inventor: KETTLE PAUL J JR
IPC: B60L15/38
Filed: 1998-10-23
Granted: 2003-03-11
Abstract: The function of a two-way end-of-train (EOT) system is coordinated with the operation of the brake equipment on a locomotive of a train according to the steps of a novel method. This method enables the brakes to be applied during an emergency in a way which minimizes the buff and draft forces produced within the train. The method includes the steps of: (1) monitoring the train for signs of an emergency by using the brake equipment of the locomotives (2) determining, if an emergency has occurred, whether the emergency is due to disjoining of the train; (3) waiting a preset time period, if the emergency was caused by disjoining of the train, before causing the brake equipment of the locomotive, to command the two-way EOT system to initiate an emergency application of the brakes from a rear part of the train; and (4) waiting an alternative time period, if the emergency was caused other than by disjoining of the train, before causing the brake equipment of the locomotive to command the two-way EOT system to initiate the emergency application of the brakes from the rear part of the train.

Title: Method and apparatus for channel estimation for multicarrier systems
Inventor: CIMINI LEONARD JOSEPH JR
IPC: H04B7/04
Filed: 1999-05-31
Granted: 2003-04-15
Abstract: A method and apparatus provide channel estimation for multicarrier systems. A minimum mean-square-error (MMSE) channel estimator makes full use of time-and frequency-domain correlations of the frequency response of time- varying dispersive fading channels. A robust channel estimator that is insensitive to the channel statistics is provided. The robust channel estimator can significantly improve the performance of a multicarrier system such as an orthogonal frequency division multiplexing (OFDM) modulation system in a rapid dispersive fading channel. In addition, the estimation process can employ a new reference generator which can select the source of the reference signal as being a decoded or undecoded signal depending on the correction success rate of the decoder.

Title: Thermal therapy devices and methods of making the same
Inventor: NEBOLON JOSEPH F
IPC: A61F7/00
Filed: 1998-02-03
Granted: 2000-10-10
Abstract: A cost effective, high heat capacity thermal therapy device (10) is described.  The therapy device (10) includes a plurality of discrete hydrophilic absorbers (30) hydrated with a liquid containing a substantial amount of water (32). The water retention mechanism of the discrete hydrophilic absorbers allows the water to freeze under normal freezer conditions (-20 ~F to 32 ~F), increasing the heat capacity of the therapy device. At the same time, the therapy device remains highly pliable when frozen as a result of reduced water flow out of the absorbers during the freezing process. The therapy device also remains highly pliable through repeated freezing/melting cycles because the discrete absorbers do not lose their discrete forms when thawed.

Abstract: L'invention concerne un procédé de certification numérique selon lequel une première signature numérique dépendante d'un premier utilisateur (102) et d'un système de premier utilisateur (102) en association, est mémorisée pour être transmise à un serveur de certification (108). L'identité du premier utilisateur (102) peut être distinguée, par exemple, par un code PIN fourni par l'utilisateur (102). Ensuite, une deuxième fois, lorsque l'utilisateur (102) souhaite obtenir l'autorisation d'effectuer une transaction (2) le système de l'utilisateur (102) génère une deuxième signature dépendant tant de l'identité de l'utilisateur que du système de l'utilisateur actuel, associé. Le système de certification (104) compare alors la deuxième signature à la première (1) telle qu'elle est mémorisée (108) pour déterminer si la transaction (6) doit être certifiée. La certification peut s'adapter à une dérive normale des composants du système ordinateur. Selon un mode de réalisation, un système d'interrogation (106) souhaitant confirmer l'identité d'un utilisateur (102) transmet un code de procédé d'identification (3) au système de l'utilisateur (102). Ce système (102) digère alors le code PIN de l'utilisateur, les signatures individuelles telles qu'elles existent sur le système de l'utilisateur (102) avec le code de procédé d'identification (3) pour générer la nouvelle signature (4). Cette nouvelle signature (4) est renvoyée au système interrogateur (106) qui la transmet au serveur de certification (104) avec le code de procédé d'identification (5). Le serveur de certification (104) digère alors le code de procédé d'identification avec la signature originale (1) telle qu'elle a été mémorisée (108) et compare le résultat à la nouvelle signature. Si ces deux signatures correspondent, alors l'identité de l'utilisateur (102) est confirmée (6). Dans le cas contraire, des critères de dérive peuvent être appliqués.

Abstract: A Layer 2 Tunneling Protocol (L2TP) receiver performs a receiver initiated recovery algorithm (RIRA) when the number of lost or out-of-order payload packets exceed a predetermined value. In particular, the receiver maintains a number of variables:  the "next sequence number expected to be received" (Sr) value, and Snl, which stores the value of the currently received "next sent" (Ns) sequence number from the latest received packet. When the value of Snl > Sr + adjustment, the receiver portion resets the value of Sr to the value of Snl and passes all packets to the upper layer of the protocol stack. The value of the adjustment variable represents the number of packets that may be dropped or out-of-order at the receiver before the receiver initiates recovery. The receiver also sends (either via piggybacking or a zero-length message) an ACK packet to inform the sender of the new Sr value at the receiver.
