Patent CA-2191118-A1 (CA)
Inventor: MAURER MICHAEL
IPC: H04B3/23
Filed: 1996-11-22
Abstract: Digital filters are used to simulate the transmission function of a real system by means of echo cancellers, where a high-speed digital signal processor with a large memory is needed to compute and update the filter coefficients.  To reduce the cost of the echo canceller, an autocorrelation, i.e. the correlation of a block of a defined number of sampling values of the transmitted signal with received echoes derived from this transmitted signal, is used by the invention to determine the time periods at which an echo arrives, and at which an update of the filter coefficients then takes place. In this way the number of filter coefficients to be computed and the cost of their computation are significantly reduced, so that echo cancellers for telephone terminals can be produced in a cost-effective manner.

Filed: 1996-11-29
Abstract: An inner boot fitting system for use with boot systems utilizing a relatively stiff outer shell and a removable flexible inner liner includes fitting structure constructed and arranged for positioning adjacent an outside surface of the liner. This fitting structure may be in the form of shims or injectable pliable containers or bags, which are used to custom fit the inner liner to an individual's foot positioned within the liner. Fitting structures are heated to the softening temperature specific to their material of construction so that material will flow away from any high pressure areas when tightened around a foot inside the assembled boot system. After heating, the assembled boot is worn for a period of time sufficient to permit the shims to deform in harmony with the pressure profile between the wearer's foot and the inside of the shell.

Title: Improved tractive effort control for recovery from a wheel slip condition in a diesel-electric traction vehicle
Inventor: HAPEMAN MARTIN JAY
IPC: B60L3/10
Filed: 1996-09-09
Abstract: A wheel slip recovery method for a locomotive in which an internal combustion engine is connected in driving relationship to an electric power generator to supply electric power to a plurality of electric traction motors coupled to drive corresponding wheel-axle sets of the locomotive. The locomotive system includes a dynamic braking function in which an electrical resistance circuit is selectively coupled in parallel circuit arrangement with the generator for selectively receiving power from the traction motors during dynamic electrical braking. The inventive method detects a wheel slip condition which cannot be overcome by transfer of power from a slipping to a non-slipping wheel and selectively couples the dynamic braking resistance circuit into circuit with the power generator in a manner to reduce power supplied to the driven wheels to a level sufficient to allow the wheels to cease slipping without reducing power output from the generator.
