Patent CA-2268495-A1 (CA)
Title: Method for determining computer network topologies
Inventor: DAWES NICHOLAS W
IPC: H04L12/56
Filed: 1999-04-09
Abstract: A method of determining computer network topologies that dramatically reduces the computational complexity and greatly increases the accuracy of connection determination. The method involves classifying ports as either up or down. A source address table is compiled for each port of each data-relay device and each port is classified as either up or down. Up ports connect to other data-relay devices which report source address tables while down ports do not. After the classification, each source address in each up port table is replaced by the source address of the data-relay devices containing the down port whose table contains that source address. The tables of pairs of up ports are compared by intersection and minimal intersection defines the most probable connection for each up port. A variety of methods are used to remove invalid source addresses and the addresses of devices that have moved during the collection of the source address tables.

Patent CA-2277972-A1 (CA)
Title: Communications protocol with improved security
Inventor: DENKER JOHN STEWART
IPC: H04L29/06
Filed: 1998-01-16
Abstract: The protocol of the present invention includes two new first level protocols and several embodiments of a second level protocol. The two new first level protocols of the present invention include the TCP2B protocol and the TCP2E protocol. In the TCP2B protocol, both client and server indicate their support for this protocol using one or more bits in TCP header. According to the TCP2B protocol, the client retransmits its requested options in the ACK message so the server need not store the options after the connection request. In the TCP2E protocol, the server maintains a Friends Table listing addresses of device recently observed to be complying with TCP. If a client's address is on the Friends Table, the connection request is processed according to TCP. Otherwise, the server sends an ACK message to the client to prompt the client to send a reset message. The client's address can then be added to the Friends Table.

Title: An automatic switch dimmer device
Inventor: BOGORAD LEV
IPC: H05B37/02
Filed: 1999-08-20
Abstract: An occupancy sensor and an automatic dimmer are connected in series with a light source. The detection of motion in the viewing area of the sensor starts the automatic dimmer which moves from its minimum brightness level to its maximum brightness level. One embodiment of the invention includes a key which can be operated to stop the automatic dimmer at some brightness level below the maximum brightness level which is reached if the key is not operated.  A second embodiment provides a presetting device whereby the brightness level can be preset. When all motion in the viewing area ceases the automatic dimmer returns the brightness level to the minimum level at a slow rate.

This steel pipe is characterized by grain size not greater than 3 µm, preferably not greater than 1 µm, elongation greater than 20%, tensile strength (TS : MPa) and elongation (E1 : %) whose product is greater than 10000, and percent ductile fracture greater than 95%, preferably 100%, measured by Charpy impact test on an actual pipe at -100°C. The structure is characterized by C : 0.005-0.03%, Si : 0.01-3.0%, Mn : 0.01-2.0%, and Al : 0.001-0.10% on a weight basis, and is composed of ferrite or ferrite and a secondary phase, with ferrite grains being not greater than 3 µm and the secondary phase having an areal ratio not more than 30°. The steel pipe is produced from a steel pipe stock having the above-mentioned composition by heating at a temperature of (Ac1 + 50°C) to 400°C and subsequently performing reducing on it at a rolling temperature of (Ac1 + 50°C) to 400°C such that the cumulative reduction of diameter is greater than 20%. The reducing is preferably performed such that at least one of rolling passes reduces the diameter by mare than 6% per pass. The steel pipe will have high ductility and high strength and will be superior in toughness and stress corrosion cracking resistance, if the content of C, Si, Mn, and other alloying elements is limited low and reducing is performed at the temperature specified above. The resulting steel pipe has good fatigue resistance and is suitable for use as line pipe.

Abstract: An electric cutting device is provided for segmenting and derinding a half section of a citrus fruit in order to collect pulp segments thereof. This device has a base made of a housing in which is mounted an electric motor with a driving shaft, and of an upwardly opened container for receiving the pulp segments of the fruit.  The device also has a fruit segmenting member sized and shaped to fit into and be supported by the top portion of the container. This fruit segmenting member includes a set of arcuate knives upwardly projecting from a ring and converging toward a common apex.  The fruit segmenting member forms a generally semi-spherical open frame on which the half section of the fruit can be applied and pressed down in order to segment radially fruit to form the requested pulp segments. The device further has a fruit derinding member sized and shaped to fit into the container below the fruit segmenting member. The fruit derinding member includes one or more arcuate blades upwardly projecting from a blade support. Each blade shaped, sized and connected onto the blade support in such a manner to extend contiguously to any one of the arcuate knives of the fruit segmenting member when the fruit segmenting member is fitted onto the base with the fruit derinding member in between. The blade support is connected to the driving shaft of the electric motor when the fruit derinding member is fitted into the container. As a result, the motor may rotate the fruit derinding member within the container below the fruit segmenting member and causes the blade(s) to derind the pulp segments from the fruit pressed down on the fruit segmenting member. The so derinded segments fall down into the container for collection.
