Patent CA-2032853-C (CA)
Inventor: HETZLER STEVEN R
IPC: G11B20/10
Filed: 1990-12-20
Granted: 1994-07-12
Abstract: A method and means is described wherein servo sectors written on a disk (or servo sections written on a tape) are equally spaced on a given track and read during seek, settle and  track  following  operations.   An  algorithm  is  used  to determine the allowable time separation between servo sectors (or  sections)  on  a  track  and  lengths  of  associated  data sections,  such as data sectors or variable length records, that may be accommodated on the disk or tape in such manner that each of the servo sectors (or sections) equally spaced on a given track is located within a data field of a data sector or within an identification region or immediately after an address indicating mark (such as address mark or index mark). The rate at which the servo sector (or section) is sampled is constant and independent of the number and lengths of the data sections.  As a result of this independent relationship, this technique is suitable for CLD recording, to banded disks using sectored  servo  as  in  conventional  FBA, and  also  even  to non-sectored  architectures,  such  as  count-key-data  (CKD), wherein the data is written in records of variable length, and to tape drives formatted in FBA or CKD.

Title: Filter cleaning apparatus
Inventor: BLACK BRENT C
IPC: B01D24/00
Filed: 1991-04-02
Granted: 2002-02-05
Abstract: The invention comprises an improvement in a cleaning apparatus particularly useful for filters. A mechanism drives a hood into position adjacent partitions. A sealing member is selectively actuated to seal off at least one such compart-ment for cleaning while the remainder of the filter remains in service. Sealing is accomplished by interaction between the hood and the partitions. The invention also relates to techniques for selectively bringing the hood into contact with the partitions, and a construction of the hood and a media support plate which allows flexibility to lift and scour the filter media using a gas to dislodge impurities, coupled with a liquid backwash involving drawing filtered water back through the media to carry away the impurities out of the filter.

Granted: 1995-12-05
Abstract: In a fiber optic gyro which is constituted by a negative feedback loop in which the phase difference between right-handed light and left-handed light propagating through an optical fiber coil is detected from their interference light and a ramp wave of a frequency corresponding to the detected phase difference is generated by a ramp generator and is applied to a feedback phase modulator to reduce the phase difference between the right-handed light and the left-handed light, a diagnostic signal generated by a diagnostic signal generator is applied via a combining circuit to the closed loop and the corresponding response signal is extracted therefrom.  Based on the response signal, a diagnostic unit diagnoses a fault of the fiber optic gyro.

Title: Mobile communications device registration method
Inventor: TIEDEMANN EDWARD G JR
IPC: H04W60/04
Filed: 1992-09-18
Granted: 2002-04-30
Abstract: A distance based method for mobile station registration in a cellular communication system. The mobile station (10) regis-ters whenever it moves into a new cell (C2) that is greater than some predefined distance from the previous cell (C1) where it re-gistered. Cell base stations (12) transmit corresponding base station location information and a distance value. The mobile station (10) receives the base station location information and computes the distance (18) from a cell (C1) in which the mobile station last registered to the current cell (C2) in which the mobile station is present.  When the computed distance is greater than the distance value associated with the registration cell the mobile station registers.  Pages for the mobile station (10) are transmitted within a group of cells (16, 20) within a distance of the registration cell corresponding to the registration cell transmitted distance value.

Title: Information broadcasting system and method
Inventor: LEVINSON FRANK H
IPC: H04N7/173
Filed: 1992-10-27
Granted: 2001-04-17
Abstract: An information broadcasting system (100) provides a large number of subscribers access to a large amount of information using one or more satellite transmission channels. The system (100) can also  use cable television transmission channels. A program supplier station (102) stores an information database (112) and tags all the  information in the database with indices so as to form a single hierarchical structure which encompasses the entire informatio n database (112). Portions of the information database (112) are transmitted often, at least once per day, in order to provide the basic subscriber with information need to access the remainder of the database (112). The information provided by the basic subscriber service, which will typically include at least 50 gigabytes of data, is available to all subscribers without requiring two way  communications between the subscribers and the program supplier station. Using a tiered system for scheduling transmission of the 5 0 gigabytes or so of information included in the basic subscriber service, as well as an intelligent subscriber request anticipation scheme for retrieving information before the subscriber asks for it, the present invention provides subscribers with reasonably quick access to all the contents of the large database while using only a modest amount of bandwidth.
