Patent CA-2172730-A1 (CA)
Title: Depolarized fiber optic rotation sensor with low faraday effect drift
Inventor: PAVLATH GEORGE A
IPC: G01C19/72
Filed: 1995-07-26
Abstract: A fiber optic sensing coil formed in a polarization-maintaining optical fiber has two optical fiber leads extending therefrom. A multifunction integrated optics chip linearly polarizes optical signals input to the sensing coil.  Fiber optic leads formed of polarization-maintaining optical fiber extend from the multifunction integrated optics chip. The fiber optic multifunction integrated optics chip leads are arranged such that the linear polarization of optical signals output from the multifunction integrated optics chip is directed along one of the principal axes of birefringence of each of the fiber optic multifunction integrated optics chip leads. Splices are formed between corresponding the first sensing coil leads and the multifunction integrated optics chip leads. The sensing coil leads and the multifunction integrated optics chip leads are arranged such that their corresponding principal axes of birefringence are at angles of approximately 45~ relative to one another. The first splice is formed a distance from the multifunction integrated optics chip such that a selected phase change between polarization components occurs in optical waves that propagate the distance L1 in the first multifunction integrated optics chip lead.

Title: Restorative composition for hard tissue and dispensing apparatus therefor
Inventor: HINO KENICHI
IPC: A61K6/884
Filed: 1995-10-13
Abstract: A restorative composition for hard tissue, comprising a paste (A) containing an inorganic calcium phosphate powder, a polymerizable monomer mixture and a polymerization initiator, and a paste (B) containing an inorganic calcium phosphate powder, a polymerizable monomer mixture and a polymerization accelerator, wherein the content of the inorganic calcium phosphate powder in each paste is 75-85% by weight, and each monomer mixture contains a monomer of the formula (1):   (see formula 1) and a monomer of the formula (2):   (see formula 2) the content of the monomer (1) accounting for 40-65% by weight of the monomer mixture as a whole. The composition can well adhere to the bone and has a sufficient water resistance. As it generates little heat upon hardening, it is less detrimental to the patient's tissues.      Furthermore, the paste has an appropriate consistency, which facilitates homogeneous mixing of the paste and application of the resultant mixture to the affected part by the use of a dispensing apparatus. Thus, the restorative composition can be used not only as a bone cement but also as a filler for the defected part of the bone, a bone prosthesis or an artificial bone.

Patent CA-2182049-A1 (CA)
Inventor: TOWNSEND PAUL
IPC: B63C11/18
Filed: 1996-07-25
Abstract: A two-stage breathing apparatus comprises a compressed air supply cylinder (1) provided with a cylinder valve (2) communicating through a high-pressure duct (3) with a manifold (4).  A first high-pressure branch (5) of the manifold (4) communicates with a pressure indicator warning unit (6) and a second high pressure branch (7), comprising a high pressure flexible hose, connects the manifold (4) via a non-return valve (8) with a high pressure quick release connector (10).  The manifold (4) contains a pressure reducer (11) which feeds a demand valve (12) provided on a breathing mask (14) via a further flexible hose (13).     The non-return valve (8) permits flow in the direction from the high-pressure quick release connector (10) to the supply cylinder (1), but prevents flow in the direction from the supply tank (1) to the high-pressure quick release connector (10). Consequently, the supply tank (1) can be replenished rapidly via the quick release connector (10), but if the connector (10) fails or the high pressure flexible hose bursts, the non-return valve prevents the loss of compressed air to the atmosphere.
Patent CA-2182124-A1 (CA)
Inventor: FOSDICK ERIC L
IPC: G06F21/00
Filed: 1996-07-26
Abstract: A method and system for managing utilization of licensed program within a distributed data processing system having a number of local systems which minimizes the amount of network communication traffic required for such management. Each permitted use of a licensed program by a distributed data processing system is indicated by a use token which may be transferred to selected systems throughout the distributed data processing system. These use tokens are then periodically redistributed throughout the distributed data processing system in response to a requested usage by a particular system within the distributed dataprocessing system. A use token transferred to a particular system is then maintained at that system upon completion of the usage until such time as a request for usage of the licensed program requires transfer of the use token to another system. In this manner the use tokens are effectively distributed throughout the distributed data processing system such that those systems most likely to request usage of the licensed program will maintain possession of the use tokens, minimizing network communication traffic.

Title: Process for determining the harmonic oscillations of the fundamental component of an electric signal
Inventor: RECK THOMAS
IPC: G01R23/16
Filed: 1995-05-16
Abstract: The present invention relates to a process for determining harmonic oscillations of a fundamental component of an electrical signal, wherein the signal is sampled with a sampling frequency corresponding to a multiple of the fundamental component's frequency. The sampled values of the signal are subjected, after analog-to-digital conversion, to a discrete Fourier transformation to determine the harmonic oscillations. The sampling is performed with a non-integer multiple of the frequency of the fundamental component and the discrete Fourier transformation is performed while the frequency resolution is increased over several periods of the fundamental component to determine the harmonic oscillations.

Title: Flash-Cut of Speech Processing Features in a Telephone Call
Inventor: BEGEJA LEE
IPC: H04M3/00
Filed: 1997-03-06
Abstract: A speech processor uses at least two speech processing features to enhance the quality of speech signals received by a user during a telephone call.  The speech processing features are applied to the speech signals.  However, the user only hears speech signals affected by one speech processing feature until both features have fully converged or ramped-up, and the two features are no longer interfering with each other.  At that point, a "flash-cut" of the second speech processing feature is activated.  The flash-cut instantaneously switches to speech signals affected by both features. This quick transition makes the speech processing features more noticeable to the user, and the user is not subjected to the period where the features interfere.  Further, an optional audio indicator is generated before implementing the flash-cut, so the user is alerted to the flash-cut, and the speech processing features are even more noticeable.

Filed: 1995-10-05
Abstract: Cette invention se rapporte à un procédé et à un appareil qui servent à traiter l'échelle de gris d'une image entrée, en particulier une étiquette d'expédition, pour la convertir en image de sortie binaire, dans laquelle les informations de premier plan sont séparées des informations d'arrière-plan et dans laquelle les contrastes entre des régions adjacentes ayant différentes densités d'arrière-plan sont effacés. Un noeud utilisant un voisinage de 5 x 5 entrées ayant une fonction d'activation neuronale est représenté. Aucun traitement linéaire explicite n'est utilisé. L'image de sortie est distordue pour correspondre à une valeur particulière des valeurs de sortie possibles, grâce à une rétroaction non linéaire en fonction à la fois de la valeur de l'échelle de gris du pixel correspondant à la position de l'étiquette mise à jour et de la valeur la plus récente de la position de l'étiquette. La contribution qui autrement est importante, fournie par un terme de gradient dans la fonction d'énergie, est supprimée par une inhibition de dérivation, lorsque cette fonction d'inhibition de dérivation détecte que le pixel se trouve sur une limite entre des régions adjacentes de différentes intensités d'arrière-plan ou à proximité d'une telle limite.
