Patent CA-2779001-A1 (CA)
Title: A dental bur storage device
Inventor: MOORE PAUL
IPC: A61C3/04
Filed: 2010-10-29
Abstract: The present invention is directed towards a dental bur storage device having a plurality of dental bur receiving holes capable of retaining a plurality of different dental bur types having different shank diameters, wherein, each of the plurality of dental bur receiving holes is tapered to allow a retaining fit to be established with any one of the plurality of different dental bur types having different shank diameters. The advantage of using a receiving hole that has a tapered form is that different types of dental burs having different diameters of shanks may be retained by the receiving holes in the dental bur storage device. This allows a wide range of different brands and different types of dental burs to be accommodated on one single dental bur storage device which greatly simplifies the process of selecting a dental bur for a dentist, particularly during a dental treatment. As the receiving hole is tapered, bur shanks of varying dimensions will be received to different depths within the receiving hole to a point where the receiving hole tapers to a diameter substantially equal to the diameter of the shank of the dental bur being received. Moreover, using this type of receiving hole, positive retention of a dental bur may be achieved when the dental bur storage device is handled roughly or inverted.

Title: Brake controller
Inventor: MATSUYAMA ETSUJI
IPC: B61H13/30
Filed: 2009-11-25
Abstract: The output pressure of a load-responsive vale (121) is controlled by a pressure-intensifying switchable solenoid valve (111). In the normal braking operation, the output pressure of the load-responsive valve (121) is intensified by the pressure-intensifying switchable solenoid valve (111). The output pressure is then adjusted to a target pressure by a brake control valve (131,132) and further supplied via an intermediate valve (141,142) to the brake cylinder (21,24). In the emergency braking operation, the pressure-intensifying switchable solenoid valve (111) is cut off and the output pressure is supplied via the brake control valve (131,132) and the intermediate valve (141,142) to the brake cylinder (21,24). In case of possible extended braking distance, the pressure-intensifying switchable solenoid valve (111) is turned on to intensify the braking force.

Patent CA-2791872-A1 (CA)
Inventor: CHOK HAMED
IPC: E21B47/06
Filed: 2012-10-10
Abstract: Clustering analysis is used to partition data into similarity groups based on mathematical relationships between the measured variables. These relationships (or prototypes) are derived from the specific correlation required between the measured variables (data) and an environmental property of interest. The data points are partitioned into the prototype-driven groups (i.e., clusters) based on error minimization. Once the data is grouped, quantitative predictions and sensitivity analysis of the property of interest can be derived based on the computed prototypes. Additionally, the process inherently minimizes prediction errors due to the rigorous error minimization during data clustering while avoiding overfilling via algorithm parameterization.  The application used to demonstrate the power of the method is pressure gradient analysis.

Abstract: A prosthetic heart valve implantable by catheter without surgery includes a substantially "dry" membrane or tissue material. In at least one embodiment, the tissue is folded in a dry state to form a tissue leaflet assembly that is then attached to a frame to form an implantable prosthetic heart valve. Alternatively, one or more tissue leaflets are operatively associated with a frame to form an implantable prosthetic heart valve. The implantable prosthetic heart valve is subsequently pre-mounted on an integrated catheter delivery system. The catheter delivery system that includes the implantable prosthetic heart valve is then packaged and transported while the tissue remains dry. The implantable prosthetic heart valve, while remaining substantially dry, can then be implanted into the receiving patient.

Abstract: An audio decoder for providing a decoded audio information on the basis of an encoded audio information comprises an arithmetic decoder for providing a plurality of decoded spectral values on the basis of an arithmetically encoded representation of the spectral values, and a frequency-domain-to-time-domain converter for providing a time-domain audio representation using the decoded spectral values, in order to obtain the decoded audio information. The arithmetic decoder is configured to select a mapping rule describing a mapping of a code value representing a spectral value, or a most significant bit-plane of a spectral value, in an encoded form, onto a symbol code representing a spectral value, or a most significant bit-plane of a spectral value, in a decoded form, in dependence on a context state described by a numeric current context value. The arithmetic decoder is configured to determine the numeric current context value in dependence on a plurality of previously decoded spectral values. The arithmetic decoder is configured to evaluate a hash table, entries of which define both significant state values amongst the numeric context values and boundaries of intervals of numeric context values, in order to select the mapping rule, wherein the hash table ari_hash_m is defined as given in Figs. 22(1), 22(2), 22(3) and 22(4). The arithmetic decoder is configured to evaluate the hash table, to determine whether the numeric current context value is identical to a table context value described by an entry of the hash table or to determine an interval described by entries of the hash table within which the numeric current context value lies, and to derive a mapping rule index value describing a selected mapping rule in dependence on a result of the evaluation.
