Abstract: A CO gas sensor includes a gas collecting vessel for purging gas to be tested, a detector which is provided in the gas collecting vessel and has electrolyte and a pair of electrodes facing each other with the electrolyte therebetween and a voltage application device which applies a voltage to the detector. One of the pair of the electrodes is a detection electrode which is active in adsorbing at least one of hydrogen gas and CO gas and being oxidized when a voltage is applied to it by a voltage application device. The gas to be tested is introduced into the gas collecting vessel in the CO gas sensor and subjected to electrolysis by a potential sweeping method or a pulse method while being brought into contact with the detector to measure the CO gas concentration in the gas by using the current value measured at the detection electrode and the variation of the current with time. With the gas sensor, CO  gas can be detected or determined with a high accuracy even in an atmosphere containing a relatively large quantity of hydrogen gas and CO2 gas.

Title: A method for reducing or preventing damage to fiber wound on a spool
Inventor: TOTA MARK S
IPC: C03B37/12
Filed: 1998-05-26
Abstract: A method for reducing or preventing damage to a fiber being wound on a spool, caused by the whipping action of a loose fiber end against fiber already wound on the spool. The method includes the steps of capturing the loose end of a fiber that is being wound on a spool against the inside surface of a non-circular guard that substantially surrounds the spool. The loose end of the fiber is captured against an angled entrance surface of the guard that extends outwardly from the guard. While the spool rotates, the fiber end is maintained against the inner surface of the guard by centrifugal force, thereby maintainingseparation of the free end of the fiber from the fiber already wound on the spool. By maintaining the free end of the fiber against the guard during spool rotation, whip damage to the fiber on the spool is substantially reduced or completely prevented.

Title: Initializer for a confusion data generator
Inventor: BARBIR ABDULKADER OMAR
IPC: H04L9/28
Filed: 1998-07-10
Abstract: A method and apparatus for the initialization of a class of non-linear confusion data generators is especially useful to enhance the security of non-linear confusion data generators that are restricted to short size secret keys or seeds. The initializer utilizes a user seed and a displacement distance to single or multiple secret key and cipher arrays to randomize confusion data generators such that their security is enhanced. The initializer provides the ability to design confusion data generators that are capable of securing large size data files as a collection of smaller size segments that can be independently decrypted for fast access and review. The initializer can be used to securely store data on a storage medium or transmit data over a communication medium.

Patent CA-2243658-A1 (CA)
Title: Dialysis device for independently controlling the concentration of at least two ionic substances in the patient's internal environment
Inventor: BENE BERNARD
IPC: A61M1/16
Filed: 1998-08-31
Abstract: A dialysis machine allows the independent control of the concentration of at least two ionic substances inside the patient, particularly sodium chloride and sodium bicarbonate, and an ionic substance A not in the dialysis liquid, so the two substances do not mix and precipitate each other out. This control is achieved by precisely controlling the flow rate of the solutions. The flow rate of the perfusion solution (Qinf) is determined as a function of the dialysis performance (D), the concentration of A in the perfusion solution ((A) sol) and the desired concentration in the patient ((A)des), e.g. Qinf = Cl x (((A)des)/((A)sol-(A)des), where Cl is the clarity of the dialysis machine for A extrapolated from the dialysis performance for sodium D. The concentration of sodium in the dialysis liquid is calculated using the formula: (Na<+>)dial = Qinf/D ((Na<+>)des - (Na<+>)sol) + (Na<+>)des where (Na<+>)sol is the concentration of sodium in the perfusion solution, (Na<+>)dial is the concentration of sodium in the dialysis liquid, Qinf is the perfusion flow rate and (Na<+>)des is the desired concentration of sodium inside the patient. The device also contains means of determining the dialysis performance for sodium by successively measuring the conductivity of at least two fluids up- and downstream of the dialysis machine (Cd1in, Cd1out, Cd2in, Cd2out). These give a dialysis performance D = Qd((Cd1out-Cd1in)-(Cd2out-Cdin))/(Cd2in-Cd1in), where Qd is the dialysis liquid flow rate.

Filed: 1998-08-26
Abstract: Methods and apparatus are described for displaying information corresponding to a current vehicle position on a display of a vehicle navigation system.  After the current vehicle position is determined by a separate process, the system determines the road on which the vehicle is currently located.  The system then refers to a map database to construct a current road database corresponding to the current road.  A current road segment corresponding to the current vehicle position is then determined.  The system then refers to the current road database to determine a first geographical location based on the current vehicle road segment.  The system then displays a text representation of the current vehicle position relative to the first geographical location.
Patent CA-2248895-A1 (CA)
Title: Nanofiber packed beds having enhanced fluid flow characteristics
Inventor: FISCHER ALAN
IPC: H01M4/86
Filed: 1997-03-05
Abstract: The general area of this invention relates to porous materials made from nanofiber packed beds. More particularly, the invention relates to altering the porosity or packing structure of a nanofiber packed bed structure by blending nanofibers with scaffold particulates having larger dimensions. For example, adding large diameter fibers to a nanotube packed bed to serve as a scaffolding to hold the smaller nanofibers apart and prevent the nanofiber bed structure from collapsing. This increases the average pore size of the mass by changing the pore size distribution and alters the packing structure of the packed bed. The increase in average pore size is caused by the creation of larger channels which improves the flow of liquids or gasses through these materials.

Patent CA-2254380-A1 (CA)
Title: Razor system with worn blade indicator
Inventor: ORLOFF GLENNIS J
IPC: B26B21/40
Filed: 1998-11-17
Abstract: The present invention is directed to a wet shaving system having an electronic indicator for indicating when the blades are becoming dull and in need of replacement. As razor blades dull, the user must exert greater force during shaving to achieve a satisfactory shave. Upon exertion of this extra force, a piston which is adjacent to the blades moves away from the blades in response to the increased forces encountered by the blades during shaving. Upon moving a sufficient distance, the piston pushes into an electronic device, such as a potentiometer, which initiates a signal processing circuit which in turn activates an indicator, such as a light-emitting diode. The activation of the indicator is a signal to the user to replace the blades.
