Patent CA-2298014-A1 (CA)
Title: Absorbent articles having a liquid swellable breathable backsheet
Inventor: CIAMMAICHELLA FABIO
IPC: A61F13/514
Filed: 1998-07-23
Abstract: The present invention relates to absorbent articles such as sanitary napkins and panty liners which are breathable by the incorporation of a breathable backsheet therein, and have a reduced tendency to exhibit garment wet through. The breathable backsheets comprise at least one moisture vapour permeable, apertured layer selected from wovens or apertured films comprising a nonsoluble, liquid swellable material such as polyvinyl alcohol, which upon contact with the fluid discharge the material swells. This causes the apertures of the layer to close and hence prevents the passage of liquid through the backsheet onto the garment of the wearer.

Title: Rotating electrosurgical blade for corneal reshaping
Inventor: SILVESTRINI THOMAS A
IPC: A61F9/013
Filed: 1998-10-02
Abstract: A rotatable electrosurgical apparatus for reprofiling a cornea is described. The apparatus includes one or more electrosurgical electrodes that extend radially outward from a center point. The electrodes are shaped to reform at least a portion of an anterior surface of the cornea. The electrodes are disposed on an electrode support, which is rotatable. The electrodes project from the bottom of a rotary handle, which rotates the electrodes about the central axis of the cornea. The rotary handle has a hollow bore and a viewing port. The apparatus includes a support base having a base ring for positioning on the eye. The base ring can hold a solution against the eye to even out irregularities in the cornea. The apparatus may include pads to exert pressure on the cornea to cause the cornea to bulge in desired areas. These bulged areas are more easily modified by the electrodes when energized. The pressure pads take different forms depending upon whether they are used for the correction of myopia, hyperopia or astigmatism.

Title: Snowmobile track belt
Inventor: COURTEMANCHE DENIS
IPC: B62D55/24
Filed: 2000-04-13
Abstract: The invention relates to an improvement in a snowmobile endless track belt of the type comprising a body made of an elastomeric material, an outer surface for contact with the ground and an inner surface provided with lugs for engagement with the snowmobile driving system and with at least one endless pathway that contacts a corresponding slide rail of the snowmobile suspension. The improvement is characterized in that the elastomeric material, in at least the area which is contacted by the slide rail, is composed of rubber and of a lubricating material so that friction generated between the slide rail and a driven belt is greatly reduced by the presence of such lubricating material in the elastomeric material.

Patent CA-2312804-A1 (CA)
Inventor: CATELLI CAMILLO
IPC: A61L2/00
Filed: 1998-12-10
Abstract: The continuous process for hyperactivation of fluids for sterilization uses a sterilizing fluid which is mixed with a gas that is inert with respect to the fluid. A sterilizing mixture is obtained which is subsequently evaporated by means of introduction into an evaporation tube in a condition of annular motion, where a liquid phase of the mixture flows against the heated walls of the evaporator at a slower speed than the gaseous phase thereof, which flows in the central zone of the evaporator, internally of the liquid phase. A  gaseous vapour/inert gas mixture is thus obtained, which is subjected to a waiting period during which the mixture flows through a transit device which transfers it to a sterilization chamber, a temperature of which is lower than a dewpoint temperature of the gaseous mixture, where a product is sterilized.

Abstract: The present invention relates to an airbag cushion which simultaneously exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a single panel together) as well as a very low amount of fabric utilized to produce the target airbag cushion, both in correlation to an overall high amount of available inflation airspace within the cushion itself. These two separate, but correlated factors, one based on an effective seam usage index are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume) and the other based on an effective fabric usage index (being the quotient of the amount of fabric utilized in the construciton of the airbag cushion and the available inflation airspace volume). The inventive airbag cushion must possess an effective seam usage factor of at most 0.11 and an effective fabric usage factor of at most 0.0330. A cushion exhibiting such low seam usage and fabric usage factors and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.

Title: Method of communication between a plurality of remote units and a control unit
Inventor: MALETSKY KERRY
IPC: G06K7/00
Filed: 1999-02-02
Abstract: In a communication system comprising a base station (10) and a plurality of asynchronously operating remote units (20, 22, 24, 26, 28), a method of communication between the base station and each of the remote units includes each remote unit randomly transmitting (208) a first bit pattern to the base unit. Upon detecting the reception of an error-free bit pattern, the base unit transmits (234) an ACK during a first window of time. The remote unit which detects the ACK during a corresponding first window of time becomes the selected unit and thereafter communicates (218) with the base station. All other remote units continue monitoring (214) for the transmission of a command belonging to a first set of commands, afterwhich the selected unit goes into a quiet mode and the unselected units resume their random transmissions of the first bit pattern to the base unit.

Abstract: A four-stage charging technique for nickel-zinc cells and batteries, is provided, whereby a high cycle life is assured, without dendrite formation or harmful overcharge, with minimal shape change of the zinc electrode, and with minimal oxygen recombination. In the first stage, the nickel-zinc cell or battery is charged with an average current less than C/5 for a period of less than five minutes, or until the terminal voltage of a cell reaches 1.75 volts to 1.79 volts. In the second stage, a fast charge is imposed, until the terminal voltage of a cell reaches between 1.88 volts and 1.92 volts. In the third stage, a moderate charge is imposed, until the terminal voltage of a cell reaches 1.90 volts to 1.94 volts. The fourth stage gives a trickle charge when the terminal voltage is greater than 1.94 volts. Typically, each of the transitions between the Stages 1 and 2 and Stages 2 and 3 is determined by a temperature dependent voltage; the transition between Stages 3 and 4 is determined by a time dependent inflection point of the terminal voltage of the cell; and Stage 4 termination is determined when dV/dt = 0.

Abstract: In producing an approximation of an original speech signal from encoded information about the original speech signal, current parameters (EnPar(i)) associated with a current segment of the original speech signal are determined from the encoded information. Reproduction of a noise component of the original speech signal is improved by using at least one of the current parameters and corresponding previous parameters respectively associated with previous segments of the original speech signal (31, 37, 39) to produce a modified parameter (EnPar(i)mod). The modified parameter is then used (25, 40) to produce an approximation of the current segment of the original speech signal.
