Title: System for controlling the pasteurization heat treatment, in particular of packaged food products, in tunnel-type pasteurizers
Inventor: PASOLI GIORGIO
IPC: A23L3/00
Filed: 1999-05-20
Abstract: A system for controlling pasteurization of packaged food product in tunnel-type pasteurizers, having a first zone for subheating, a second zone for heat treatment and a third zone for cooling. The zones include thermally independent subzones, some of which comprise heating and cooling means. Data detection and processing means measure and record a temperature of the product in each zone or subzone, to identify when the product first reaches a selected pasteurization temperature in the second zone; maintain it at the selected pasteurization temperature for a required period of time; and only after that period, lower the temperature to a predetermined value which is maintained until the product leaves the second zone. The product is thus maintained at the pasteurization temperature for the correct time period, is heated and cooled only once, regardless of conveyor stoppages, thus avoiding the risk of insufficient pasteurization or over--pasteurization, and saving thermal energy.

Title: Method for converting an existing subscriber to a wireless communications system
Inventor: YU BEE YUN
IPC: H04M3/42
Filed: 2000-03-24
Abstract: A subscriber conversion system determines at least one code for an existing subscriber of a first wireless communications system to be converted to a second wireless communications system. When the existing subscriber obtains a wireless unit to be used in the second wireless communications system, the conversion system uses the at least one code provided to the existing subscriber to link existing subscriber information from the first wireless communications system to information associated with wireless unit for the second communications system, thereby improving the efficiency of the conversion process. For example, if a service provider wishes to convert from GSM to CDMA, the service provider can provide a secret code and an identification number, such as a directory number (DN), as the codes to the existing GSM subscriber. The subscriber obtains a CDMA wireless unit and commences an activation process to activate the CDMA wireless unit. As part of the activation process, the subscriber provides the secret code and the identification number to the conversion system. The conversion system determines if the secret code and the identification number correspond to the secret code and identification number provided to an existing GSM subscriber. If so, information which is characteristic of the CDMA wireless unit, such as the ESN, DN and/or IMSI, is associated with at least a portion of existing GSM subscriber information, such as billing information and/or features or services. As such, the conversion system uses existing subscriber information to reduce the time required to convert the existing subscriber to the wireless communications system based on the second radio standard.

Patent CA-2309499-A1 (CA)
Inventor: WEEKS RICHARD
IPC: G06F17/30
Filed: 1998-11-18
Abstract: A method and apparatus is provided for extracting key terms from a data set, the method including the steps of identifying a first set of one or more word groups of one or more words that occur more than once in the data set, and removing from this first set a second set of word groups that are sub-strings of longer word groups in the first set. The remaining word groups are key terms. Each word group is weighted according to its frequency of occurrence within the data set. The weighting of any word group may be increased by the frequency of any sub-string of words occurring in the second set and then dividing each weighting by the number of words in the word group. This weighting process operates to determine the order of occurrence of the word groups. Prefixes and suffixes are also removed from each word in the data set. This produces a neutral form of each word so that the weighting values are prefix and suffix independent.
