Title: Public key cryptography utilizing elliptic curves
Inventor: MULLIN RONALD C
IPC: G06F7/544
Filed: 1995-07-31
Granted: 2010-12-21
Abstract: An elliptic curve encryption system represents coordinates of a point on the curve as a vector of binary digits in a normal basis representation in F2m. A key is generated from multiple additions of one or more points in a finite field. Inverses of values are computed using a finite field multiplier and successive exponentiations.  A key is represented as the coordinates of a point on the curve and key transfer may be accomplished with the transmission of only one coordinate and identifying information of the second. An encryption protocol using one of the coordinates and a further function of that coordinate is also described.

Abstract: Un appareil et une méthode pour installer temporairement un rail latéral comme une barre en z pendant linstallation dun ensemble porte. Lappareil comprend une structure dassemblage qui coopère avec une attache pour positionner avec précision le rail latéral à un emplacement souhaité sur un élément structural comme un montant de porte. Dans le cas de rails latéraux articulés, le rail latéral peut être aligné sans que la porte y soit attachée pendant que lemplacement de lattache est établi. La structure dassemblage peut aider au bon placement de lattache dans lélément structural. Une fois lattache en place, le rail latéral peut être retiré de lélément structural sans retirer lattache. La porte peut ensuite être fixée au rail latéral pour former un ensemble de porte / rail latéral. Lensemble porte / rail latéral est alors mis en prise avec lattache pour un positionnement temporaire et précis pendant que le rail latéral est fixé à lélément structural.

Abstract: A bus arbitration scheme is implemented in a system where an arbitrary assembly of nodes on a system bus have been resolved into an acyclic directed graph. The hierarchical arrangement of nodes has one node designated a root while all other nodes have established parent/child relationships with the nodes to which they are linked. Each node may have a plurality of connected child ports with a predetermined acknowledgment priority scheme established. Fair bus access arbitration provides for bus granting in a sequence corresponding to the predetermined port priorities allowing all nodes a turn on the bus. The root node may always assert its priority access status to gain bus access which is useful for accommodating a root node which requires isochronous data transfer. Alternatively, a token passing arbitration scheme may be implemented where the token for bus access is passed around the nodes according to the above-described predetermined port priority scheme. Preemptive bus initialization may be triggered by any node upon detection of a necessitating error or addition or removal of a connection to an existing node.

Abstract: An exhaust gas treatment system includes a hydrogen adder, a first reduction catalyst, an oxygen concentration adjuster, a state measurer, an oxygen concentration controller, and a hydrogen addition controller. The first reduction catalyst is disposed on a downstream side of the hydrogen adder for reacting the hydrogen with nitrogen oxides in the exhaust gas to reduce and remove the nitrogen oxides. The oxygen concentration controller controls the oxygen concentration adjuster so the concentration of oxygen in the exhaust gas obtained from the internal combustion engine measured by the state measurer, a data map based on the state, and a predictive equation based on the state and amounts of change becomes less than a predetermined value. The hydrogen addition controller controls the hydrogen adder so as to add the hydrogen to the exhaust gas when the concentration of oxygen in the exhaust gas is less than the predetermined value.

Abstract: An object of the present invention is to quickly perform convergence of a time average allocated bandwidth on a target bandwidth. In the invention, an optical line terminal calculates a requirement threshold for each optical subscriber unit based on a difference between the time average allocated bandwidth of each optical subscriber unit and the target bandwidth, and notifies a corresponding optical subscriber unit of the calculated requirement threshold. The corresponding optical subscriber unit then notifies, based on the data amount accumulated in a buffer, the optical line terminal of a data amount, as a transmission requirement, up to a data separation that is less or equal to the notified requirement threshold and in which a maximum transmission amount can be transmitted. The optical line terminal then notifies the corresponding optical subscriber unit of a transmission permission amount in which the data equal to the transmission requirement of which the optical line terminal is notified can be transmitted. The corresponding optical subscriber unit then transmits the data amount corresponding to the transmission permission amount.
