Title: Computer based records management system and method
Inventor: JOHNSON JUDY J
IPC: G06F17/40
Filed: 1995-07-28
Abstract: A computer based records management system comprises an information filter for assuring that record data units offered to the system for storage arecomplete and not redundant. These record data units may be electronic in nature,scanned from paper, digitally formed from audio, video, or otherwise formed as digital data information media, an objective of the disclosed system being to eliminate paper or microform record keeping. If record data units comprising documents are incomplete or redundant, the data units may be queued for special handling, returned or otherwise disposed of. Record data units accepted for system entry are acknowledged and preferably tagged to enable tracking and forwarded for unit verification and certification. Verification and certification includes examination of units for compliance with preset criteria. Once a unit is found to meet the criteria, the unit is stored in permanent storage along with adisposal schedule determined for that unit. Only users meeting predetermined security levels may alter or dispose of a stored unit prior to scheduled disposal. Moreover, reasons for such alteration or destruction are required from the cleared user, and an associated data field must be completed. Consequently, the present system provides for record data unit tracking and audit trails in the event of any requirement for regulatory or legal compliance with discovery or other record unit requests. The present invention also permits recontruction of the record units of an enterprise in the event of a catastrophic event.

Patent CA-2157493-A1 (CA)
Inventor: BLOW KEITH JAMES
IPC: H04B10/2507
Filed: 1994-08-10
Abstract: The invention relates to the control of soliton-soliton interaction through the application  of a positive phase shift. For each soliton width there is a critical phase modulation level above which soliton-soliton interaction can be virtually eliminated.  This enables the spacing between adjacent solitons to be reduced, increasing the system bandwidth even for long transmission distances. The invention finds application in submarine and other long haul systems.

Inventor: TORNAI RICHARD
IPC: G06F1/32
Filed: 1994-07-27
Abstract: The provision of power to a peripheral of a computer system is controlled by receiving input signals from an input source, such as a keyboard (28), mouse (22), printer port (24), or an occupancy sensor (26). The input signals are then processed to determine whether power should be provided to the individual peripherals. In response to an activation signal, the peripheral connected to an external power source (44). Thereafter, the input signals are processed to determine whether power should be disconnected from the peripheral.  In response to a deactivation signal, the peripheral is disconnected from the power source (44). A processor (32) monitors the input signals and determines whether the peripherals should be powered or not. The processor (32) generates the activation and deactivation signals. Peripheral power is automatically turned off when the peripheral is not needed in order to minimize power consumption.

Abstract: In a method and apparatus for molding a lining in a pipe, a hot-meltable fluorine resin material is sealed in the pipe.  The fluorine resin material is uniformly diffused on an entire inner circumferential face of the pipe by rotating the pipe.  The fluorine resin material is urged against the inner circumferential face of the pipe by increasing a rotation speed of the pipe up to a predetermined rotation speed.  The fluorine resin material urged against the inner circumferential face of the pipe is melted by heating the pipe to a predetermined temperature equal to or higher than a melting temperature of the fluorine resin material and less than a foaming temperature of the fluorine resin material.          After the fluorine resin material is entirely melted, the fluorine resin material is cooled while rotating the pipe, thereby forming the lining having a predetermined thickness on the inner circumferential face of the pipe.
