Title: Speech immunity enhancement in linear prediction based dtmf detector
Inventor: WIKSTROEM PER MAGNUS
IPC: H04M1/738
Filed: 1999-02-04
Abstract: To determine whether a received signal represents a dual tone multi frequency (DTMF) code, a characteristic of the received signal is repeatedly measured over a period of time, thereby obtaining a plurality of parameter measurements. This may include separating the received signal into low band and high band signals and for each of the low band and high band signals, determining a plurality of squared magnitude measurements over the period of time. A deviation value is then determined for each of the plurality of parameter measurements, and an average deviation value is determined from the plurality of deviation values. The average deviation value is compared to a threshold value, thereby obtaining a comparison result. The received signal as alternatively designated as representing or not representing a DTMF  code on the basis of the comparison result. The step of determining a deviation value for each of the plurality of parameter measurements may include, for each of the plurality of squared magnitude measurements, determining a deviation from a predefined (e.g., unit) circle only if the squared magnitude measurement is less than the radius of the predefined circle, and setting the deviation equal to zero for all other cases. The step of determining the average deviation value from the plurality of deviation values may include determining which of the plurality of deviation values is a maximum deviation value, and determining an average deviation value from the plurality of deviation values not including the maximum deviation value.

Patent CA-2296651-A1 (CA)
Inventor: BLACK MARTIN THOMAS
IPC: B24B23/03
Filed: 2000-01-19
Abstract: An orbital disc sander support is provided which may support an active orbital disc sander in a stationary position so that an operator can attend to other tasks without having to de-activate the sander or worry that the sander will fall off of the work area.  This both helps to protect the sander and increases operator efficiency by eliminating time wasted waiting for the orbital disc to reach its operating speed or to stop before continuing with the next task. The support has a turntable, which includes a platform rotatably mounted to a base, and may employ a retaining wall for retaining the sander. The base may be provided with a cushion to absorb vibrations and to prevent the base from slipping off the work area. Alternatively, the base may simply be secured to the work area. The platform may also be provided with a rubber pad to help clean the sanding disc surface of the orbital disc sander. This cleaning action may extend the life of the sanding disc surface; thereby increasing efficiency by reducing how frequently the sanding disc surface must be replaced. Additionally, the platform may be provided with a hole to allow any grit or dust that has been removed from the sander surface to escape.

Patent CA-2305702-A1 (CA)
Title: Elastomer composite blends and methods for producing them
Inventor: MORGAN ALLAN CLARK
IPC: B60C1/00
Filed: 1998-09-28
Abstract: Elastomer composite blends are produced by novel wet/dry mixing methods and apparatus. In the wet mixing step or stage, fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Elastomer composites are produced. Such elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved. The coagulum produced by such wet mixing step, with or without intermediate processing steps, is then mixed with additional elastomer in a dry mixing step or stage to form elastomer composite blends. The additional elastomer to the coagulum may be the same as or different from the elastomer(s) used in the wet mixing step.
