Patent CA-2306327-A1 (CA)
Title: Blossom/wilt for dynamic reallocation in a distributed fiber system
Inventor: SABAT JOHN JR
IPC: H04B10/12
Filed: 2000-04-19
Abstract: A technique for controlling a wireless communication network to provide for blossoming capacity to a relatively high capacity state and/or wilting capacity to a relatively lower capacity state.  Connections in progress with active subscriber units are properly handled without the need to send explicit handoff commands from the base stations. The cell sites may be advantageously implemented with cable microcell integrators that comprise remotely deployed transceiving equipment that are interconnected to centrally located base transceiver station equipment via a broadband cable distribution network. In an initial relatively low capacity state, adjacent cells are operated at the same carrier frequency such that they form simulcast groups so that subscriber units traveling in adjacent cells will operate with the same radio channel. As demand increases, the power level of an auxiliary radio transceiver is gradually increased while the power level of the original transceiver in the cell is gradually decreased. Once the auxiliary transceiver is operating at full power on the second channel, the mobile units in the cell will have completed their internal soft handoff processing and switch over to the new channel. An analogous inverse process can be used to wilt the capacity of the system.

Title: Methods and apparatus for efficient synchronous mimd operations with ivliw pe-to-pe communication
Inventor: MORRIS GRAYSON
IPC: G06F9/38
Filed: 1998-11-06
Abstract: An SIMD machine (160) employing a plurality of parallel processors (PEs) (104) in which communications hazards are eliminated in an efficient manner. An indirect Very Long Instruction Word instruction memory (VIM) (106) is employed along with execute and delimiter instructions. A masking mechanism may be employed to control which PEs have their VIMs loaded. Further, a receive model of operation is preferably employed. In one aspect, each PE operates to control a switch (107) that selects from which PE it receives. The present invention addresses a better machine organization for execution of parallel algorithms that reduces hardware cost and complexity while maintaining the best characteristics of both SIMD and MIMD machines and minimizing communication latency. This invention brings a level of MIMD computational autonomy to SIMD indirect Very Long Instruction Word (iVLIW) processing elements while maintaining the single thread of control used in the SIMD machine organization. Consequently, the term Synchronous-MIMD (SMIMD) is used to describe the present approach.

Abstract: System and method for examining a file (1) associated with a digital computer (2) to determine whether a computer vines is present within the file (1). The file (1) contains at least one numbered sector. When the file (1) is examined for an initial time, the file (1) is scanned by an antivirus module (3, 5). At that time, the numbers of the sectors being scanned and a hash value for each scanned sector are stored into a critical sector file (4). The hash values can be calculated by an antivirus accelerator module (5). When the file (1) is examined a subsequent time, all of the file (1) sectors that wore scanned the initial time are examined by the antivirus accelerator module (5). Each of these sectors again has its hash value calculated and compared with the hash value of the corresponding sector as stored within the critical sector file (4). When any calculated hash value fails to match a corresponding stored hash value for any sector, the antivirus scan module (3) is commanded to rescan the entire file (1).

Title: Interactive voice personal and live connection telephone messaging system
Inventor: ARSENAULT STEVEN J
IPC: H04M15/00
Filed: 1999-11-24
Abstract: In existing "voice personal" ads, users are not charged for "browsing" the voice mail messages on the system. Consequently, a large percentage of users of the telephone lines required for such a system are using the system free of charge by merely browsing, which causes an uneconomic use of the majority of the lines. "Live connection systems" can charge for time on the system but require more expensive equipment and monitoring than a basic "voice personals"  system, and so most newspapers utilize only the standard "voice personals"  arrangement. There is therefore a need to increase the revenue of such voice personals systems by encouraging users to switch to a "live connection system". The present invention provides a method of inter-connecting a "voice personal system" and a "live connection system" which would alert the voice personals "browser" of the presence of potential live connections and transfer the browser to the live connection system.
