Abstract: Un générateur (30) de signaux de sous-porteuses comprend un filtre (40) à réponse impulsionnelle finie (RIF) qui répond à des coefficients RIF choisis à partir d'un registre (44) de coefficients. Un premier ensemble de coefficients RIF représente une forme de sous-porteuse et une fréquence centrale idéales. Une étape d'étalonage effectuée par un dispositif (34) d'étalonage surveille le   signal de sous-porteuse résultant et produit un nouvel ensemble de coefficients RIF correspondant généralement à la forme de signal de sous-porteuse et à la fréquence centrale idéales, cet ensemble présentant toutefois une prédistorsion selon le complément d'erreur détecté dans le signal réel de sous-porteuse. En chargeant ensuite le nouvel ensemble de coefficients RIF, puis en mettant en fonction le générateur (30) de sous-porteuse, des prédistortions dépendant de la fréquence dans l'étage de sortie du générat  eur (30) de sous-porteuse annulent la prédistortion réfléchie d  ans les nouveaux coefficients RIF. En conséquence, il en résulte un signal de sous-porteuse haute qualité sans utilisation de dispositifs à étage de sortie coûteux dans le générateur (30) de signal de sous-porteuse.

Patent CA-2226307-A1 (CA)
Title: Absorbent products having conforming means
Inventor: ULMAN JOHN
IPC: A61F13/53
Filed: 1998-01-06
Abstract: This invention provides protective products feminine hygiene absorbent such as sanitary napkins that have conforming means in their end regions that, in use, facilitate the products' ability to fit close and conform to the body, resist transverse bunching and prevent leakage of fluid from the edges. The conforming means consists of a stiffened element and a nonstiffened region immediately adjacent the stiffened element that cooperate to bend, fit and conform. The stiffened element, such as an embossed channel or regions that are stiff, densified or reinforced, bends along its axis of bending and resists bending and compression orthogonal to that axis. The nonstiffened relatively unconstrained region puffs outward to fit and conform to the body.      The center region of the napkin may optionally contain a stiffening means, such as extra absorbent material, a sphagnum moss containing insert and an embossed channel; the stiffening means of the censer region being spaced apart from the stiffened element of the end region. The absorbent product may also optically have cuffs, or optionally have undergarment wrapping wings, where such cuffs or wings synergistically cooperate with the conforming means of this invention to provide full and reserve coverage of and conformability to the body.      This is true for cuffs, and especially for wings, and most especially for wings that are attached inwardly of the longitudinal edges of the absorbent element, such wings providing gathering of the crotch of the undergarment without diminishing the strike zone that is available to capture body fluids.

Title: Magic smile
Inventor: NOWZARI NADER
IPC: A46B15/00
Filed: 1998-03-17
Abstract: This circuit consists of the following components:   1. BT2 ~-3.6 VDC battery 2. R2    ~-390 .OMEGA. Resistor 3. D2    ~-LED Diode 4. ADT05 ~-Thermostatic Switch 5. C2    ~-0.1 Uf Capacitor 6. Rset  ~-Temperature Setting Resistor (Here 33 K.OMEGA.) Circuit description: BT2 is used to power-up the circuit. LED D2 provides the light behind the smile on the brush. The intensity of this light is determined by the value selected for resistor R2. Smaller values of R2 will generate a more intense light. Capacitor C2 is used for decoupling purposes and maintains the battery output at a constant level. Thermostatic Switch ADT05 is a temperature controlled switch that actually monitors the mouth temperature and turns the LED diode ON, when this temperature exceeds the preset value (using Rset). ADT05 is functionally identical to part AD22105, both IC's are available in surface mount packaging but ADT05 has 5 pins where AD22105 has 8 pins of which 3 are not used. Analog Devices (AD) had planned to start manufacturing ADT05 as of January 1999 but due to lack of demand they did not produce any, since similar item 8 pin configuration (AD22105) is already offered in the market.  So the prototype brush provided to you has an AD22105 inside rather than an ADT05.   Ambient temperatures of 20-30 °C will not TURN-ON the LED. Brushing temperature on the tip of the brush starts to rise towards 34.7°C (since Rset=33K.OMEGA.). Once temperature is above 31 (there is a 4°C Hysteresis). Triggering temperature can be changed using a different value for Rset using the formula provided in technical specifications for ADT05 & AD22105.
