Patent CA-2143600-A1 (CA)
Title: Hydraulic motor swash plate angle shifter
Inventor: BUSTAMANTE RALPH
IPC: F16H63/30
Filed: 1995-02-28
Abstract: A speed control shifter is provided for use with an hydraulic automotive drive train. The shifter is intended for co-axial mounting on an existing variable speed reciprocating hydraulic pump swash plate angle control shaft. It employs a pair of input plates each intermittently connected to an output plate rigidly connected ti the shaft. One input plate is connected to a speed selector handle, the other input plate is linked to an accelerator cable. When starting from neutral activation of one solenoid causes the position of the output plate, and hence the swash plate, to be controlled by motion of the accelerator cable. This allows the automobile to move away from a stopped position as the engine accelerates from idle. Once a first chosen speed range is reached a second solenoid is activated to link the motion of the output plate to the position of the speed selector, and the first solenoid is de-activated to permit normal increases and decreases in speed within the chosen speed range.

Title: Method for allocating files in a file system integrated with a raid disk sub-system
Inventor: HITZ DAVID
IPC: G06F17/30
Filed: 1995-12-21
Abstract: The present invention is a method for integrating a file system with a RAID array (1030) that exports precise information about the arrangement of data blocks in the RAID subsystem (1030). The system uses explicit knowledge of the underlying RAID disk layout to schedule disk allocation. The present invention uses separate current-write location (CWL) pointers for each disk (1022) in the disk array (1030) where the pointers simply advance through disks (1022) as writes occur. The algorithm used has two primary goals. The first goal is to keep the CWL pointers as close together as possible, thereby improving RAID (1030) efficiency by writing to multiple blocks in the stripe simultaneously. The second goal is to allocate adjacent locks of a file on the same disk (1022), thereby improving read back performance. The first goal is satisfied by always writing on the disk (1022) with the lowest CWL pointer. For the second goal, another disk (1024) is chosen only when the algorithm starts allocating space for a new file, or when it has allocated N blocks on the same disk (1022) for a single file. The result is that CWL pointers are never more than N blocks apart on different disks (1024), and large files have N consecutive blocks on the same disk (1022).
