Patent CA-2509010-A1 (CA)
Inventor: KOLOMIETS SERGEY
IPC: G06F3/023
Filed: 2005-06-02
Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Title: System and method for authenticating software using hidden intermediate keys
Inventor: CRAFT DAVID J
IPC: G06F17/00
Filed: 2003-12-15
Abstract: A processing unit (300) includes a read-only encryption key (394). Loader co de image (250) is loaded into system memory (205) from non-volatile storage (270). Loader code image (250) includes a prefix value (225) and a suffix value (235). The prefix value (225) is combined with the master key (394) fr om the processing unit (300) to create a random value that is the seed for a hashing algorithm. The hashing algorithm uses the seed value with a signatur e formed from the blocks of code to form a result. During the hashing algorith m, intermediate key values are generated and stored in a memory area inaccessib le by the user. The intermediate key values are used by the loader code after t he loader has been authenticated and loaded. The loader combines one or more of the intermediate key values with prefix and suffix values that correspond to other software modules to authenticate the software, using a hashing algorithm, and load the software upon authentication.

Abstract: A user of an instant messaging system may store names of other users of the instant messaging system on a participant list (which may be referred to as a ~buddy list~), and the names may be categorized into one or more groups.  Similarly, a user of a mobile device, such as a mobile telephone, may store contact information about people on the mobile device. Information describing the on-line presence of the user within the instant messaging system or geographic location of a mobile device, such as a mobile telephone associated with the user system, may be disseminated to users on the participant list or people on the contact list based on geographical location information that is associated with groups of users or contacts. A user interface enables a user to specify the manner of disseminating on-line presence information and/or geographic location information to groups of users or contacts. Information describing the on-line presence of the user within the instant messaging system or the geographic location of a mobile device, such as a mobile telephone associated with the user, may be disseminated to users on the participant list or top people on the contact list base on notification information that is associated with groups of users or contacts. A delegation model may be used to control whether a user is permitted to make modifications to the notification information. The user may use multiple identities to communicate within the instant messaging system and/or with the mobile communications device or devices. The user can maintain sets of temporal periods for each of the multiple identities. Only one identity may be used at a specific time to communicate to a specific other identity, but the multiple identities of the user may be linked such that on-line presence and/or geographic location associated with one of the identities is disseminated based on the temporal periods set for one or more of the multiple identities.

Title: Method for producing functional nanocarbon and hydrogen by direct decomposition of lower hydrocarbon
Inventor: NAKAMURA SATORU
IPC: C01B31/02
Filed: 2006-03-28
Abstract: In a reaction where a lower hydrocarbon is subjected to direct decomposition by using a catalyst to produce a functional nanocarbon and hydrogen, the lower hydrocarbon is subjected to the reaction in an coexistent gas comprising low concentration of oxidizing gas, reducing gas or a mixture thereof. The precursor of functional nanocarbon produced on the catalyst and amorphous carbon secondarily produced on the catalyst react with the coexistent gas so that being removed from the catalyst, making it possible to prevent the drop of conversion with time on stream due to the inhibition of the reaction by the precursor and by-product. In the case where the raw material of lower hydrocarbon is biogas, the coexistent gas can be easily contained in methane by lowering purification degree of methane. Further, hydrogen can be obtained as one of decomposition products of lower hydrocarbon thus can be contained in methane during the reaction.
