Patent CA-2268128-A1 (CA)
Inventor: SHALIT AMIR
IPC: G06F11/10
Filed: 1997-10-03
Abstract: A method and apparatus for dynamically expanding an N drive RAID set to an M drive RAID set while maintaining data integrity, where the M drive RAID set includes one or more new drives. The method comprises the steps of identifying a destructive zone in the N drive RAID set including destructive zone data (400). Thereafter the destructive zone data is mirrored in the M drive RAID set by copying it to a free location in the N drive RAID set (408) and to a location in a new drive in the M drive RAID set (410). Finally, the N drive RAID set is expanded to an M drive RAID set (414). Data integrity is assured in the N drive RAID set during migration by maintaining mirrored destructive zone data until the expansion step has completed migration of the destructive zone of the N drive RAID set (416).

Patent CA-2274327-A1 (CA)
Inventor: KIELLAND PETER
IPC: B62M3/08
Filed: 1999-05-27
Abstract: The invention provides a bicycle stand, which includes a prop that may be attached to a bicycle pedal. Attachment of the prop to the pedal may be by a "socket-bolt" having a hole in one end and a threaded hole in the other. The socket-bolt replaces the lock nut normally located on the bearing spindle of a pedal. In one embodiment, the socket and prop may include socket and prop having the same polygonal cross section thereby preventing rotational instability of the inserted prop-member. The prop-member may be substantially "L" shaped, thereby providing a ground contact point located below and outboard of the pedal. When the pedal assembly is rotated near its lowest point, the bicycle can be securely tilted onto the prop-member. The prop-member may also be configured to serve as a lever that applies torque to standard mechanic's toolbits.

Abstract: In a mobile communication system, independent versions of a signal are transmitted over plural antennas. The antennas are either spatially separated or orthogonally polarized with respect to each other so that the independent versions of the signal are not subjected to correlated fading. Each independent version of the signal is transmitted from a respective antenna a fixed delay after transmission of a previous version of a signal from a different antenna. The fixed delay is at least one information bit of the signal. Received versions of the signal are equalized in an equalizer or RAKE architecture to provide a composite signal. The equalizer has respective sets of equalizer taps that are separated from adjacent sets of equalizer taps by the fixed delay. The RAKE architecture has respective sets of RAKE  forgers that are separated from adjacent sets of RAKE fingers by the fixed delay.
