Patent CA-2511819-A1 (CA)
Inventor: KUNG WILLIAM
IPC: H04B1/26
Filed: 2004-01-08
Abstract: The present invention relates generally to communications, and more specifically to a method and apparatus for generating local oscillator signals used for up- and down-conversion of RF (radio frequency) signals. A major problem in the design of modulators and demodulators, if the leakage of local oscillator (LO) signals into the received signal path. The invention presents a number of highly integratable circuits which resolve the LO leakage problem, using regenerative divider circuits acting on oscillator signals which are running at a multiple or fraction of the frequency of the desired LO signal, to generate in-phase (I) and quadrature (Q) mixing signals. Embodiments of these circuits also use harmonic subtraction and polyphase mixers, as well as virtual local oscillator TM (VLO) mixing signals. VLO mixing signals are signal pairs which emulate local oscillator signals by means of complementary mono-tonal and multi-tonal mixing signals.

Title: Silicon production apparatus
Inventor: NAKASHIMA JUNICHIROU
IPC: C30B29/06
Filed: 2004-08-17
Abstract: A polycrystal silicon manufacturing apparatus capable of preventing molten silicon from being solidified at the lower end of a reaction tube due to the lowering of temperature at the lower end when the inner surface of the reaction tube is heated to a temperature equal to or higher than the melting point of silicon and deposited silicon is fallen to a lower collection part for collection. The apparatus comprises an infrared ray radiating device heating the outer periphery of the lower end part (2a) of the reaction tube (2) by infrared ray or a temperature lowering prevention means such as a lower end side coil (4L) formed of a coil near the lower end of a high-frequency heating coil (4) and having a heating strength increased more than that of a coil (4U) located above near the lower end part. When the reaction tube (2) is heated by the high-frequency heating coil (4), the temperature of the lower end part (2a) can be prevented from being lowered by the temperature lowering prevention means.
Patent CA-2519324-A1 (CA)
Title: Medical devices with enhanced ultrasonic visibility
Inventor: KEENAN JAMES
IPC: A61B19/00
Filed: 2004-02-10
Abstract: A medical device having enhanced ultrasonic visibility is provided. The device permits localized drug delivery, probe positioning, fluid drainage, biopsy, or ultrasound pulse delivery, through the real-time ultrasound monitoring of the needle tip position within a patient. The device permits controlled dispersion of a drug into solid tissue, the lodging of particles into solid tissue, and drug delivery into specific blood vessels. As a needle is inserted, a fluid that contrasts echogenically with the organ environment is injected into the patient. The fluid travels a brief distance before being slowed and stopped by the patient's tissue and this fluid flow will be detectable by ultrasound. The needle position during insertion will be monitored using ultrasound until it is at the desired point of action. A therapeutic drug is then delivered or a probe inserted through the needle to perform therapies such as tumor ablation using RF heating. The fluid flow rate may be adjusted during insertion to maintain a properly defined image of the needle tip. At the point of action, the echogenic fluid can be pulsed, repeatedly and at varying flow rates, until the fluid dispersion pattern is satisfactory and the drug can then be delivered. Ultrasound can also be delivered through the. needle using a transducer mounted in the handheld assembly.

Title: Easy open ring binder
Inventor: WHALEY PAUL A
IPC: B42F13/26
Filed: 2005-10-20
Abstract: A ring metal (10) has binder rings (12-16) each comprised of two ring segmen ts one end of each of which is attached to a hinge plate (18, 20). A movable bar (3 4) extends from one end of the metal to the other and contacts the hinge plates to move them when the binder is opened. A manually operated trigger (32) connects to one end of th e bar to move the bar. The trigger includes a slot (40) in which is fitted a pin (44) connected to the bar. The pin moves in the slot as the trigger is moved. Drawing the trigger away from a binder closed position toward a binder open position moves the pin through the slot . This causes the bar to move relative to the hinges, forcing the hinges to pivot the respective segments of each binder ring away from each other and open the binder. When the binder i s closed, a nib (62) formed on the top of the bar is received in an opening in a shield (22) of the metal to prevent the trigger from being inadvertently moved and opening the binder.</ SDOAB>

Title: Multi-sensor high-resolution extraction of heart sounds
Inventor: HANKINSON STEPHEN
IPC: A61B5/0452
Filed: 2005-10-26
Abstract: The present invention describes the use of a low-noise signal that is processed to indentify waveform timing reference points that are used to provide the reference points with which a high-resolution, high precision representative waveform is extracted from a noisy quasi-periodic signal. For example, the representative waveform of a noisy biological signal of a patient is determined with temporal and amplitude resolution and precision by evaluating a plurality of physiological signals acquired from the patient. For example, a medical device may evaluate a plurality of physiological signals such as electrocardiogram (EKG) signals, phonocardiogram signals, and optical plethysmograph signals for features that are indicative of the timing of the cardiac pulse and extracts from the phonocardiogram a representative waveform of the first and second heart sounds. The present invention may also be configured to extract representative waveforms of other physiological signals and representative waveforms of noisy, quasi-periodic signals in other fields of application.

Patent CA-2527378-A1 (CA)
Inventor: COON LARRY
IPC: C03B37/04
Filed: 2005-11-18
Abstract: A duct assembly is employed for directing a central air flow upwardly toward the rotating spinner assembly of a rotary-type fiberizer that produces a downwardly flowing column of fibers. The central air flow eliminates the low-pressure zone that normally occurs beneath the spinner assembly of conventional fiberizers. The cross-sectional profile of a lower portion of the duct is vertically elongated where the duct passes through the fiber column so as to facilitate the flow of the fiber column over the duct. A shielding member can be positioned to deflect the central air flow away from the spinner assembly and against the interior of the fiber column to insulate the spinner assembly from the relative cool air flow.  In another embodiment, a conduit extends through the fiberizer spinner assembly and directs a cooling gas beneath the spinner assembly within the interior of the fiber column.

Title: Pipe indexer/kicker
Inventor: LESKO GERALD
IPC: E21B19/14
Filed: 2006-02-01
Abstract: A combination pipe kicker/indexer for attachment to a pipe launcher is provided. The pipe kicker includes an articulated arm that is operated by a rotating shaft. The arm has a kicker head that rises up from a frame and moves towards a pipe located in the trough of the pipe launcher. Continued rotation of the shaft causes the kicker head to push the pipe out of the trough. Reversing the shaft rotation retracts the kicker arm into its frame. The indexer includes a plate having two eccentric cam openings and a cam rotatably mounted therein. Rotation of the cams causes either end of the indexer plate to rise up from the frame and urge a section of pipe towards the pipe launcher trough.
