IPC: A01N59/20
Filed: 2004-06-17
Abstract: A wood preservative includes injectable particles comprising one or more sparingly soluble copper salts. The copper-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Exemplary particles contain for example copper hydroxide, basic copper carbonate, copper carbonate, basic copper sulfates including particularly tribasic copper sulfate, basic copper nitrates, copper oxychlorides , copper borates, basic copper borates, and mixtures thereof. The particles typically have a size distribution in which at least 50 % of particles have a diameter smaller than 0.25 ~m, 0.2 ~m, or 0.15 ~m. At least about 20 % and even more than 75% of the weight of the particles may be composed of the substantially crystalline copper salt.

Third, the calculated parameter values for the incoming products for the two or more types of end products, respectively, are normalized so as to meet the production goals while at the same time achieving optimum parameter values. Fourth, for each incoming product, the end product with the best (e.g., largest) normalized parameter value is selected as the end product to be produced from the incoming product.

Patent CA-2535617-A1 (CA)
Inventor: SINIVAARA HASSE
IPC: H04B7/26
Filed: 2004-06-18
Abstract: The present invention provides an operational mode of communication which adjusts a transmitting power of a cellular system and a mobile terminal used inside a vehicle, such as an aircraft, so that the mobile terminals (102) inside the aircraft camp on the indoor cellular network (100) inside the aircraft and do not interfere with external cellular networks. This reduces possible electromagnetic interference with avionics inside the aircraft, because the transmitted power levels is limited. The frequency band used by the indoor cellular network can be determined by the service provider independent of frequency bands allocated by communication specifications and regulations. Conventional mobile terminals (102) and conventional base transceiver stations (104) applying the aircraft profile according to the invention can be used inside the aircraft while aboard to communicate with the conventional external cellular networks (150).

Title: Method and apparatus for trust-based, fine-grained rate limiting of network requests
Inventor: TOOMEY CHRISTOPHER NEWELL
IPC: G06F/
Filed: 2004-11-17
Abstract: A method and apparatus for fine-grained, trust-based rate limiting of network requests distinguishes trusted network traffic from untrusted network traffic at the granularity of an individual user/machine combination, so that network traffic policing measures are readily implemented against untrusted and potentially hostile traffic without compromising service to trusted users. A  server establishes a user/client pair as trusted by issuing a trust token to the client when successfully authenticating to the server for the first time.  Subsequently, the client provides the trust token at login. At the server, rate policies apportion bandwidth according to type of traffic: network requests that include a valid trust token are granted highest priority. Rate policies further specify bandwidth restrictions imposed for untrusted network traffic. This scheme enables the server to throttle untrusted password-guessing requests from crackers without penalizing most friendly logins and only slightly penalizing the relatively few untrusted friendly logins.
