Patent CA-2275530-A1 (CA)
Inventor: SALASIDIS ROBERT
IPC: A61D7/00
Filed: 1999-06-18
Abstract: An apparatus for the automatic delivery to an animal of a beneficial agent such as analgesia by infusion with the pain of the animal being taken into account when determining the rate of dispensing the agent. As the pain experienced by an animal and therefore its distress is manifested in increased agitation, the apparatus includes elements for the measurement of the frequency and amplitude of an animal's movement and the generation of a trigger signal when the either the frequency or the amplitude exceeds a predetermined threshold. The trigger can be used to generate a visual or audible alarm. The apparatus also preferably includes a dispensing means for delivering doses of beneficial agent to the animal in response to the trigger signal. The apparatus serves primarily to reduce the post-operative distress experienced by an animal by providing for timely administration of analgesic compounds. The apparatus also aids the animal care-giver by reducing the amount of time spent assessing the animal and administering beneficial compounds.

Title: Phase retrieval in phase contrast imaging
Inventor: GUREYEV TIMUR
IPC: G03B42/06
Filed: 1997-12-24
Abstract: A method of obtaining an image of the phase change introduced by an object in penetrating radiation incident on the object includes irradiating the object with penetrating radiation having high lateral spatial coherence, and receiving at least a portion of the radiation at a detector after the radiation has emerged from the object and thereby obtaining and storing at least two intensity records for the received radiation each including intensity values at predetermined intervals. These values are utilised to derive a grid of values defining an image of the phase change introduced by the object in the penetrating radiation. The intensity records are obtained at a uniform finite distance after the radiation has emerged from the object, and are for respective different energy distributions of the detected radiation. Apparatus is also disclosed.

Title: Tire uniformity testing system
Inventor: BORMET FRANCIS J
IPC: B60C25/00
Filed: 1998-01-22
Abstract: A tire uniformity testing system includes a testing station mounted on a gantry-like frame structure and an inlet conveyor located adjacent to the testing station. The inlet conveyor receives a tire and centers the tire such that its rotational axis is located at predetermined distance from the rotational axis of the testing station and a conveyor transports the tire to the testing station. The testing station includes rotatable chuck assembly for engaging and rotating a tire which in turn is engaged by a loadwheel that generates tire uniformity data. The inlet conveyor is mechanically isolated from the testing station. The frame forming part of the testing station includes a plurality of I-beams joined together in flange abutting relationship which, in addition to producing a mechanically rigid structure, provides spaces defined between the flanges of the beams that are suitable for routing electrical wiring, pneumatic or hydraulic lines, etc. The tire uniformity machine has a width dimension that is at least 10% greater than a depth dimension and this feature coupled with an integral crane increases the accessibility and serviceability of components in the machine. A probe system is positioned between two adjacent vertical I-beams so that the bulk of the mechanism is protected and only distal ends of the probe extend into the testing region. The probes themselves include magnetic breakaway couplings which allow sensors to decouple from the ends of the probe should contact occur between a probe and a tire being tested.

Abstract: The invention concerns a device and method for determining the level of nitric oxide in exhaled air, where an initial device is arranged to determine the current portion of nitric oxide and/or the distribution of nitric oxide over time during an exhalation phase. During the commencing period of the exhalation phase, the exhaled air is arranged to pass with no or with only a very small resistance or back-pressure to a free space, and during the remaining period, the exhaled air is arranged to pass through the said initial device against the action of a suitable resistance or back-pressure. Further, portions of the exhaled air can be distinguished from the flow of exhaled air by collecting or diverting portions corresponding to fractions or multiples of the estimated dead space of the individual under study.

Title: Controlled energy density microwave-assisted processes
Inventor: PARE J R JOCELYN
IPC: B01J19/12
Filed: 1999-11-01
Abstract: An effect is induced within a chemical system consisting of at least two substances having differing degrees of microwave transparency, by exposing the mixture to focused microwave energy having a generally uniform energy density level, and an energy density at a level exceeding the capacity of at least one of the substances to dissipate the energy as thermal energy. The treatment is carried out until the thermodynamic state of the system is in a non-equilibrium state. The rate at which the effect is carried out is substantially increased over that which would be expected under equilibrium thermodynamic conditions.

Patent CA-2289897-A1 (CA)
Inventor: BRADY JAYNE
IPC: H04Q11/04
Filed: 1999-11-18
Abstract: The SONET/SDH multiplexing hierarchy is extended to very high rates by creating new virtual containers of a higher capacity, and their associate pointers. The multiplexing hierarchy nests the pointers into the payload, so that the number of pointers on the high capacity line is importantly reduced, as the high rate spans of the network do not see the STS-1/STM-1 pointer granularity. Fewer pointers results in reducing the current complexity of pointer processing. The complexity of the multiplexing hierarchy is also reduced by the use of larger containers. The hierarchy may be extended to higher rates, as needed, and may also be used for other technologies, besides SONET/SDH.

Inventor: BUCKLEY THOMAS J
IPC: A01K85/01
Filed: 2000-03-27
Abstract: Artificial fishing lures normally are used by casting on and into the water whereupon they are left statically and are moved in varying degrees and methods by tugging on of the fishing line. A more effective lure would have some simple built-in motion mimicking the movements and vibrations of an insect or small animal, and without movement of the attached fishing line which can be detrimental as it detracts from the lure itself. To give this illusion, this invention employs gas produced from a reactant placed by the fisherman into the lure. The pressure and volume of the gas is used to produce simple mechanical movement and the flow of gas is used to produce bubbling, thereby creating forms of animation.

Title: Athletic shoe midsole design and construction
Inventor: KITA KENJIRO
IPC: A43B13/20
Filed: 2000-06-14
Abstract: A midsole assembly for an athletic shoe comprises a midsole 3 formed of soft elastic material, a corrugated sheet 4 interposed in the heel portion of the midsole 3, a plurality of transverse holes 6, 7 formed at the contact regions of the midsole 3 with the corrugated sheet 4, and through holes 10, 11 extending vertically and communicating with the transverse holes 6, 7. In using this shoe, air flows into the shoe through the transverse holes 6, 7 and the through holes 10, 11, and thus, good ventilation can be acquired especially at the heel portion of the inside of the shoe. Moreover, because the shape of the transverse holes 10, 11 is maintained by the action of the corrugated sheet 4, the transverse holes 6, 7 can be prevented from being crushed by the impact load applied onto the midsole 3 at the time of impacting the ground. In such a way, ventilation can be secured in an athletic shoe as well.
