Title: Revetements routiers
Inventor: BEAMISH SHAWN
IPC: E01C9/08
Filed: 2003-07-28
Abstract: L'invention porte sur un revêtement routier amovible comprenant un corps pourvu d'une première extrémité formée d'une première face et d'une seconde extrémité réciproque formée d'une seconde face. Le premier raccord est positionné au niveau de la première extrémité et comporte une partie s'étendant depuis la première extrémité constituée de deux parties comprenant un grand élément de raccord femelle et un élément de raccord mâle plus petit de façon à recevoir des éléments positionnés de manière analogue de la seconde face sur la seconde extrémité.

Title: Cache accessing method and apparatus
Inventor: SACHS HOWARD G
IPC: G06F12/1045
Filed: 1990-01-23
Abstract: IMPROVED CACHE ACCESSING METHOD AND APPARATUS                    ABSTRACT OF THE INVENTION         An addressable cache memory stores a plurality of lines of data from the main memory, and a tag memory (typically a part of the cache memory) stores a corresponding plurality of real addresses associated with each line of data.  A cache accessing unit receives a virtual address from a CPU.  The virtual address comprises a real address portion and a virtual address portion, and the virtual address portion includes a virtual page and segment address.  On each cache access, the cache accessing unit initially addresses the cache memory by concatenating the real address portion of the virtual address with an algorithmically determined first real address (i.e., a real page address).  A translation memory translates the virtual address portion of the virtual address into a second real address as the cache memory is being accessed.  A comparator compares the second real address with the first real address, and the data is retrieved from the cache memory when the first real address matches the second real address. All subsequent cache accesses are made using a combined address formed by concatenating the real address portion of the current virtual address to the previously translated real page address.

Abstract: An adjustable frequency motor drive system for a hoist is disclosed in which the frequency of the power supply to the motor can be selectively varied and the speed of the motor will follow the varying frequency at a slip speed relative to the frequency.  The slip speed of the motor may not exceed a value beyond which the motor can control the hoist load.  Accordingly, a frequency value based on the frequency of the power supply to the motor is selected as the frequency which is not to be exceeded by the motor speed expressed as a frequency. Signals representative of the actual motor speed and the selected frequency value are compared and,  if the signal representative of the motor speed exceeds the signal representative of the frequency value which is not to be exceeded, an output signal is produced which may be used to apply a brake which stops and holds the motor and hoist and thereby maintains the load suspended.  A motor speed deviation time period may also be provided and the hoist brake not applied to the motor until the time period is exceeded.

Patent CA-2017898-A1 (CA)
IPC: H04M9/08
Filed: 1990-05-30
Abstract: Abstract of the Disclosure An echo canceler-suppressor speakerphone arrangement effectively addresses the limitations of regeneration and reverberant return echo inherent in the design of speakerphones. The tendency for regeneration is eliminated by employing adaptive echo cancellation in the receive path of the speakerphone arrangement to cancel speakerphone talker echo across a hybrid and thereby reduce the local loop gain to below unity. And the generation of a reverberant return echo to the far-end party is avoided by employing adaptive echo suppression in the transmit path of the speakerphone arrangement. Near-full and full duplex operation are regularly achieved since the receive path remains open at all times and the transmit path has its gain reduced only to the level necessary to suppress excessive reverberant return echo.
