Patent CA-2394100-C (CA)
Title: Porous calcium phosphate cement
Inventor: ZITELLI JOSEPH
IPC: C04B28/34
Filed: 2001-10-10
Granted: 2007-12-11
Abstract: A kit and a method for making a porous cement which self sets to hydroxyapatite and has an interconnected porosity is produced by mixing a calcium source and a phosphate source with a carbona te source and mixing this powdered component with a liquid component having an acid component. The liquid component comprises water on an aqueous solution containing an acid. The acid and the carbonate react to form carbon dioxide thereby producing an interconnected porosity in the normally solid self-hardening bone cement. The method requires only a relatively low weight percent of the acid and base to be mixed with the liquid and powder cement components.

Title: Hybridisation beacon and method of rapid sequence detection and discrimination
Inventor: FRENCH DAVID JOHN
IPC: G01N33/58
Filed: 2001-03-28
Granted: 2010-05-18
Abstract: A method for detecting specific DNA sequences and discriminating single nucleotide polymorphisms (SNPs) using fluorescently labelled oligonucleotide probes is disclosed. Oligonucleotide probes are labelled with a reporter molecule preferentially attached to an internal nucleotide residue.  The fluorescence emission of oligonucleotide probes varies significantly when in single-stranded and double-stranded states despite the absence of quencher moieties, allowing reliable detection of complementary DNA targets. The melting temperature of probe/target duplexes permits discrimination of targets that differ by as little as a single nucleotide residue, such that polymorphic targets may be discriminated by fluorescence quantitation and Tm. The hybridisation probes of this invention have been demonstrated to accurately identify homozygous and heterozygous samples using a single fluorescent oligonucleotide and direct investigation of saliva with hybridisation probes permits ultra-rapid genotypic analysis within 35-40 minutes. Target detection and SNP discrimination assays have been achieved in homogeneous, heterogeneous, 'real-time' and solid-phase formats.

Abstract: The present invention relates to a system and device which allows the replacement of a damaged thread in an object (12) with a thread identical to the damaged thread by enlarging the original threaded hole and inserting a thread-insert (10) in a newly threaded hole in the object which has an internally threaded hole identical to the original threaded hole. The thread-insert is fastened into the enlarged hole using a thread that securely holds it in place. When the thread-insert is threaded into the enlarged threaded hole, a pocket (11) formed below the drive head of the thread-insert causes metal flow into the pocket to create a seal between the thread-insert and the object.

Abstract: La présente invention concerne un procédé et un système qui permettent d'évaluer le fonctionnement d'un alternateur sur la base d'une composante de fréquence du signal de sortie de l'alternateur. Le procédé consiste à détecter une composante de fréquence du signal de sortie de l'alternateur, à comparer la composante de fréquence du signal de sortie de l'alternateur à un seuil de fréquence et à évaluer le fonctionnement de l'alternateur sur la base d'un résultat de la comparaison. Si la composante de fréquence du signal de sortie de l'alternateur est inférieure au seuil de fréquence, l'alternateur est estimé défectueux. Afin d'obtenir la composante de fréquence, le signal de sortie de l'alternateur est comparé à un seuil adaptatif qui est lui-même généré à partir du niveau de signal de crête et du niveau de signal de vallée du signal de sortie de l'alternateur, tels que la moyenne des niveaux de signaux de crête et de vallée.

Abstract: A dough product (20) suitable for storage by refrigeration or freezing that includes a package (22) constructed as a chub from a substantially gas impermeable material closed at opposite ends (29, 30) around a dough portion (24) containing at least flour, a liquid, and a leavening system. The package includes at least one gas transfer passage (34). The leavening system at least partially proofs the dough after insertion into and closing of the package, such that the dough (24) expands to a volume substantially equal to the volume of the package (22) and has a high raw specific volume. The proofed dough bears against and seals the gas transfer passage (34) to thereby arrest further proofing and prevent oxygen entry into the package. The dough product (20) is then stored at refrigeration or freezing temperatures for later baking, without additional proofing, into a bread product having a high baked specific volume.

Abstract: Voicemail notification messaging for mobile communication devices is disclosed. Voicemail notification messages corresponding to voicemail messages are received through a wireless receiver of the mobile device and voicemail message header lines corresponding to them are displayed in a message list. The mobile device receives the voicemail notification messages from several different voicemail systems for consolidating voicemail message processing using a single common user interface. Preferably, the mobile device provides a graphical user interface (GUI) for the end-user with visual objects corresponding to PLAY, REWIND, FAST FORWARD, SKIP BACK, SKIP FORWARD, as examples, which provides for transparency of voicemail system-specific commands. Advantageously, each voicemail notification message includes voicemail message summary information, such as a calling party identifier, a message time stamp, and message length, for use in providing voicemail message header information in the message list. In addition, each voicemail notification message includes voicemail message retrieval/processing information, such as a voicemail access telephone number, a voicemail message identification number, and voicemail message processing commands, for use in providing the system interface transparency.

Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression:
