Patent CA-2299348-A1 (CA)
Inventor: WOTTRENG ANDREW HENRY
IPC: G06F12/08
Filed: 1998-10-14
Abstract: A system and method for performing computer processing operations in a data processing system (10) includes a multithreaded processor (100) and thread switch logic (400).        The multithreaded processor is capable of switching between two or more threads of instractions which can be independently executed. Each thread has a corresponding state in a thread state register (440) depending on its execution status. The thread switch logic contains a thread switch control register (410) to store the conditions upon which a thread will occur. The thread switch logic has a time-out register (430) which forces a thread switch when execution of the active thread in the multithreaded processor exceeds a programmable period of time. Thread switch logic also has a forward progress count register (420) to prevent repetitive thread switching between threads in the multithreaded processor. Thread switch logic also is responsive to a software manager (460) capable of changing the priority of the different threads and thus superseding thread switch events.

Title: Intelligent disk brake assembly
Inventor: CONSTANS ALAIN
IPC: B60T13/14
Filed: 2001-03-05
Abstract: The present invention describes an innovative IBS braking system in which the regulation components are integrated with the brakes. The specific location of the fluid inlet components at the bottom of the brake and the return components positioned at the top of the brake present advantages for the renewal of the brake fluid. In the case of electronic failure, braking control is assured by a specific isolation device integrated within the brake.      The general architecture of the control system can be totally decentralized due to the ability to integrate the various regulation methods of the brake: sensors, computers, and solenoid valves. This new concept, "intelligent brake", uses the various signals supplied by the vehicle's computers to self-regulate.
