Title: Mobile radio communication system, mobile station, and method for controlling diversity hand-over branch
Inventor: OHTANI TOMOYUKI
IPC: H04B7/02
Filed: 1998-06-03
Abstract: A method for selecting a branch candidate by means of a mobile station at which a branch candidate is selected by taking the maximum numbers of wired branches and the maximum numbers of wireless branches of a mobile station into consideration and a method for controlling a diversity hand-over branch on a network side at the time of executing DHO, when pluralities of adding branch candidates and deleting branch candidates are detected at the mobile station. The mobile station contains the pluralities of adding branch candidates and deleting branch candidates, namely, all DHO candidates in onoe hand-over trigger signal and informs stations in the network of the same. More specifically, the adding branch candidates are contained in the adding information parameter of the hand-over trigger signal, while the deleting branch candidates are contained in the deleting information parameter of the trigger signal. On the network side, in addition, the adding branch candidates and the deleting branch candidates are separated from each other and the candidates are sequentially executed in order to avoid the complexity of processing.

Title: Method of operating an internal combustion engine
Inventor: HELLMICH WOLFRAM
IPC: F02B17/00
Filed: 1997-10-15
Abstract: The invention relates to a method of operating an internal combustion engine, or an internal combustion engine. According to the inventive method of operation, fuel is injected into a combustion chamber in such a way that it is reflected on a piston. A stratified charge thus arises in the combustion chamber. Choked or unchoked fresh air is sucked into the combustion chamber independent from the load condition of the combustion engine, so that the combustion gas from the previous working cycle is completely expelled from the combustion chamber. Combustion engine power output is substantially produced via the injected quantity of fuel. The inventive method enables a stratified charge, ideal for the combustion of air/fuel mixture, to be obtained. As a result, the internal combustion engine disclosed in the invention runs quietly at ideal combustion gas values.

Title: Method and apparatus for upgrading software subsystems on a network system
Inventor: EITNER WILLIAM H
IPC: G06F9/445
Filed: 1999-05-19
Abstract: A method and system for updating a software subsystem while services are being provided by the software subsystem is provided. Initially, instructions are processed from a primary software subsystem loaded at a first base address associated with a primary storage unit. A secondary software subsystem is downloaded at a second base address associated with a secondary storage unit while the primary software subsystem is being executed. The secondary software subsystem typically contains an updated version of the primary software subsystem. To install the updated software subsystem, the first base address associated with the primary storage unit is swapped with the second base address associated with the secondary storage unit. Execution continues using the updated software subsystem without a significant interruption in service.

Patent CA-2277585-A1 (CA)
Inventor: JACK ROBERT F
IPC: F04B43/073
Filed: 1999-07-13
Abstract: An air driven double diaphragm pump including two opposed pump chambers with an air motor having air chambers therebetween. The pump chambers and air chambers form pumping cavities divided by diaphragms. Each pump chamber includes an inlet ball valve and outlet ball valve. An inlet manifold is positioned below the pump chambers and an outlet manifold above. Tie-rods extend both across the pump from one pump chamber to the other with nuts to place the assembly in compression. Tie-rods also extend from the outlet manifold through the pump chambers, to the inlet manifold and to feet mounted therebelow. Two plates, one to either side of the air motor extend to grooves in the inlet and outlet manifold and also extend to grooves in the pump chambers so as to close of the side of the pump structure. With the plates, an outlet manifold is provided from which air may be exhausted remotely. The ball valves include small diametrical clearance and a limitation on lift for added performance. The ball valves also include seats which are sealed with the components of the pump through the use of O-rings and surfaces polished to 10RA.      Belleville washers relieve thermal stresses on the tie-rods. Integrally molded diaphragms include an annular sheet about a hub. A semi-circular corrugation about the periphery provides for attachment to the pump while a cylindrical flange mates with a boss on the respective pump chamber. A stud is molded as an insert into the diaphragm.      The pullout failure rate of the stud is empirically established by appropriate sizes of circumferential ribs and hub thickness to be higher than the rupture rate for the annular sheet. Thus, failure occurs before air chamber contamination.

Title: Detecting and locating a misbehaving device in a network domain
Inventor: HARDJONO THOMAS P
IPC: H04L29/06
Filed: 2000-02-16
Abstract: A technique for detecting and locating a misbehaving router divides the network domain into multiple sectors and uses a two-level authentication scheme to allow a receiving device to authenticate that a particular packet originated in a particular sector. More specifically, an originating device includes a sector tag and a device tag in the packet. The sector tag is computed using a sector key known to all devices in the network domain, and allows any receiving device to authenticate the originating sector for the packet. The device tag is computed using a device key known only to the device and to a secure and trusted authority within the same sector. Upon receiving the packet, a receiving device authenticates the packet by computing a sector verification tag and comparing the sector verification tag to the sector tag in the packet. If the sector verification tag does not match the sector tag in the packet, then the receiving device drops the packet. If the sector verification tag matches the sector tag in the packet, but the packet includes invalid data, then the receiving device forwards the packet to a secure and trusted authority in the receiving sector. The secure and trusted authority in the receiving sector forwards the packet to other secure and trust authorities in other sectors.  Each secure and trusted authority that receives the packet is able to determine whether any device in its sector is the originating device for the packet by computing device verification tags for each device in the sector and comparing the device verification tags to the device tag in the packet.

Abstract: The invention concerns electrochrome mirrors comprising, as central component, an optically active cell consisting of two glass plates (1, 2) arranged as a laminate, each provided, on the inside, with a plane electrode, an electrochromic substance (5) being placed between the two plane electrodes. The two glass plates (1, 2) are sealingly connected to each other, by means of an adhesive bead (6) enclosing the perimeter of said glass plates (1, 2) at their peripheral edge, while leaving free a narrow edge strip. In order to ensure that a connection wire (8a, 8b) is more securely fixed without modifying the dimensions of the mirror, each edge strip of the plane electrodes is divided in two by a separating trench (9a, 9b), thereby forming an edge strip section (11a, 11b) such that the edge strip section isolated from one of the plane electrodes is opposite to the edge strip section not isolated from the other plane electrode. In each space included between said edge strip sections, is incorporated a connection wire (8a, 8b), using an electroconductive material.
