Patent CA-2184946-A1 (CA)
Title: Generation of cryptographic signatures using hash keys
Inventor: SPRUNK ERIC
IPC: H04B7/15
Filed: 1996-09-06
Abstract: A method and apparatus are provided for generating a digital signature that authenticates information of a plurality of different information groups. Information from each group is hashed to produce a separate hash key for each group authenticating the information in that group. Particular combinations of the hash keys are hashed together to produce at least one combined hash key. Each of the hash keys is ultimately combined in a predetermined order with all other hash keys via the combined hash keys to produce the digital signature in a manner that authenticates the information of all of the information groups. The digital signature is reproducible without access to all of the information groups authenticated thereby. Instead, information from a first information group is provided together with a set of hash keys and combined hash keys embodying authenticated information from the other groups. The hash key for the first information group is produced locally and combined with the other hash keys and/or combined hash keys in order to reproduce the digital signature.

Title: Control device and mouthpiece
Inventor: WELTI NEAL ARTHUR
IPC: B60R25/04
Filed: 1995-03-28
Abstract: A control device, such as a breathal-yser, has an interlock which acts to control access to/or use of an apparatus, like a vehi-cle, by a person under the influence of alco-hol. The device is provided with a means for determining whether the interlock has been bypassed by monitoring the line voltage of the vehicle and determining with reference to a perceived condition, such as ignition status, whether the voltage level monitored is cor-rect. A mouthpiece of the breathalyser has a relatively straight through design so that con-densate internal of the mouthpiece gravitates to the bottom of the mouthpiece and is ex-pelled out by the passage of air. The mouth-piece has a channel (13) in one end creating a venturi effect and thereby developing laminar flow. The interlock has a detachable memory module which provides for easier download-ing of recorded information and also provides a mechanism by which the operating program of the interlock can be updated.

Title: Direct reduction process for iron oxide-containing materials
Inventor: CIP GERHARD
IPC: C21B13/00
Filed: 1995-06-20
Abstract: A direct reduction process for iron oxide-containing materials is dis-closed. Synthesis gas is mixed with top gas produced during direct reduc-tion of iron-oxide-containing materi-als and is used as reduction gas for direct reduction. In order to avoid or reduce metal dusting caused by an in-creased CO content of the reduction gas by a simple and economical tech-nique and with a simple and economi-cal equipment, while reducing energy consumption, the H2O content of the reduction gas is set between 1 and 2 %, preferably at approximately 1.5 % by washing away the CO2 contained in a partial volume of top gas before the top gas is used as reduction gas, the washed top gas is mixed with syn-thesis gas, is directly brought to a pre-determined temperature by irrigation and at the same time saturated with H2O, after direct irrigation it is heated up to a temperature above I saturation temperature by admixture of non-washed top gas, and is then used as reduction gas.

Patent CA-2210333-A1 (CA)
Inventor: KIEVAL ROBERT S
IPC: A61N1/368
Filed: 1996-01-26
Abstract: A dual chamber pacemaker is provided having capability for adjusting the AV escape interval so as to optimize the timing of delivered ventricular pace pulses for therapy of patients with cardiomyopathy. The pacemaker system continually monitors to determine when a delivered pace pulse results in a fusion beat, and periodically adjusts the AV escape interval in accordance with the percentage or rate of incidence of such fusion beats. In one specific embodiment, the pacing system determines the percentage of delivered ventricular pace pulses which are followed by fusion beats over a predetermined number of intervals, and decrements AV escape interval when such percentage is not below a predetermined minimum. The pacing system also periodically increments AV escape interval when the rate of fusion beats is acceptable, thereby providing a closed loop system for maintaining the AV interval at an optimally long value consistent with maximizing full capture by delivered ventricular pace pulses. In another embodiment, the V-V escape interval of a non-tracking mode pacemaker is controlled to optimize pre-excitation of the ventricle.

Title: Device for operating a discharge lamp
Inventor: YOSHIOKA MASAKI
IPC: H05B41/24
Filed: 1997-01-13
Abstract: The invention relates to a device for operating a fluores-cent discharge lamp of the outer electrode type. As claimed in the invention a switching device is turned on and off by driver signals with a stipulated frequency, by which on the secondary side of a transformer the periodic voltage wave-form shown at A in Figure 1 is produced. This voltage wave-form is applied to the fluorescent discharge lamp of the outer electrode type, and thus operation is effected. For the above described periodic voltage waveform, with respect to repetition period t 2 W o < t, if the width at a vol-tage of the waveform of 0 V which has a single maximum peak value within one period is labelled W o, its full width at half maximum (the width between a and b in Figure 1) being set to a stipulated value (for example, to a value of less than or equal to 2.5 µsec). This makes it possible to maintain stable emission even if the pressure of the gas filled in the discharge lamp is increased. In this way high illumination intensity can be obtained.

Filed: 1997-09-25
Abstract: A novel fastener comprising a head, shaft and tip, the tip having an indent formed therein such that the rim of the indent portion forms a cutting edge, and methods of making same is provided. The invention is particularly suitable for use with nails but is also useful for fasteners such as screws and spikes. The indent and cutting edge of the tip provides for a fastener which requires less force to be driven into isotropic materials such as concrete and anistropic materials such as wood and exhibits greater holding power than conventional fasteners such as diamond pointed nails. The use of the fastener of the invention in association with wood reduces the chances of the wood splitting as the fastener is being driven.
