Title: Internet protocol filter
Inventor: COLVIN WILLIAM G
IPC: H04L12/46
Filed: 1997-04-23
Granted: 2002-11-05
Abstract: The IP filter (12), embodying the present invention, is a communications device designed to provide public network (14) or Internet (16) access to nodes (18) of private networks (10), advantageously without requiring the private nodes on such networks to register public Internet addresses. The IP  filter presents a single IP address to the Internet and uses a plurality of IP  ports to solve the problem of IP address conservation. It initiates sessions by assigning private side IP sessions to a unique port of the IP filter's public address. The IP filter effects a translation between a source port number for the private network and a destination port number for the public network for communication therebetween. Benefits of the IP filter include private node security and conservation of Internet-registered addresses.

Granted: 2001-12-11
Abstract: Multi-phase fluid flow in a pipeline (12) or other flowline is minitored using a combination of flow type detectors. One set of detectors monitors the interfaces between fluid interfaces and the other monitors the presence of different fluid phases around the periphery of the flowline. The relative volumetric fluid flow rates can be measured by detecting changes in the phase interfaces between two sets of sensor rings (14, 16) using sensors (20, 22, 24 and 26) spaced around the flowline with the fluid flow type being detected across the flowline with an annular capacitance detector. The sensors rings typically use ultrasonic transducers (28, 30, 32 and 34) for detecting the phase interfaces while the capacitance device indicates the presence (or absence, of different phases around the periphery of the flowline (12). By combining the outputs of the different detectors, an indication of the flow phenomena in the flowline can be obtained. The flowrate in the line can be measured directly using a concentrically, oriented set of hot wire anemometers or a concentrically oriented set of thermopiles spaced equally around the flowline in conjunction with the annular capacitance device.

IPC: G06F3/06
Filed: 1999-04-12
Granted: 2003-12-09
Abstract: In a disk drive, a transparent record access manager centralizes access to system cylinder records in two global routines for reading and writing to the system cylinder records, and a system cylinder table which maintains address information for the system cylinder records. Internal firmware system cylinder record users and host software programs access system cylinder records through the system cylinder record manager, which in turn locates system cylinder records through the system cylinder table. The transparent record access manager makes any changes to the address or length of a particular system cylinder record transparent to the users of all other system cylinder records. An ATA command process allows a host processor to access a system cylinder record through the read and write routines, or to recieve the system cylinder table from the disk drive.

Granted: 2004-02-10
Abstract: Le système de suspension et d'insonorisation est du type dans lequel un revêtement de finition d'une maison ou d'un édifice est retenu à une surface solide d'infrastructure au moyen d'une pluralité de cylindres de caoutchouc pourvus chacun d'une cavité ouverte s'étendant dans une direction axiale. Chaque cylindre est attaché à la surface solide au moyen d'une bande de suspension pourvue de deux extrémités opposées, qui est glissée dans la cavi té du cylindre et dont les deux extrémités sont repliées sur la surface solide et y sont attachées. Le revêtement de finition est attaché à des barres de suspension qui sont elles-mêmes attachées aux cylindres à l'aide d'attaches passant dans les cavités du cylindre. Selon l'invention, les cavités des cylindres de caoutchouc sont axialement décentrées et les cylindres sont orientés lors du montage de façon à ce que les cavités décentrées soient plus proches de la surface solide que des barres de suspension. De plus, les attaches sont constituées chacun d'une autre bande de suspension façonnée et dimensionnée pour recevoir et supporte une des barres de suspension, cette autre bande de suspension étant en forme de U et comprenant une portion centrale et deux côtés opposés perpendiculaires à la portion centrale, chaque côté ayant au moins un trou et une épingle façonnée et dimensionnée pour être insérée dans les trous des côtés de l'autre bande tout en passant dans la cavité d'un des cylindres. Ceci a l'avantage de minimiser les chances de contact entre, d'un e part, les bandes de suspension servant d'attache des cylindres de caoutchouc à la structure de l'édifice, et d'autre part, les moyens servant à l'attache des barres de suspension aux cylindres de caoutchouc. Ceci a également l'avantag e d'assurer une meilleure insonorisation, en fournissant une couche de caoutchouc plus large entre les barres de suspension et leur attache.</SDOAB >
