Patent CA-2149828-C (CA)
Inventor: MCNEILL JAMES DUNCAN
IPC: G01V3/11
Filed: 1995-05-19
Granted: 2003-11-25
Abstract: A method for surveying terrain uses transient magnetic fields transmitted from a coil in plane parallel to and above the terrain, transient voltage response from vertically spaced receiver coils coaxial with and parallel to the transmitter coil being processed to detect highly conductive objects buried in the terrain, with the ratio of the response of the coils optionally being used to estimate the depth of objects. The responses from the coils are scaled in a predetermined ratio to provide cancellation of the response from objects in a layer of terrain at a particular depth, which layer may be at the surface to remove surface responses, or beneath the surface so as to allow surface objects to be differentiated from deeper objects by providing responses of opposite polarity.

Granted: 2009-01-27
Abstract: A method and apparatus for delivering a medicine to a patient via the patient's respiratory system with control and efficiency. A nebulization catheter is positioned in the patient's respiratory system so that a distal end of the nebulization catheter is in the respiratory system and a proximal end is outside the body. In a first aspect, the nebulization catheter may be used in conjunction with an endotracheal tube and preferably is removable from the endotracheal tube. The nebulization catheter conveys medicine in liquid form to the distal end at which location the medicine is nebulized by a pressurized gas or other nebulizing mechanism. The nebulized medicine is conveyed to the patient's lungs by the patient's respiration which may be assisted by a ventilator. By producing the aerosol of the liquid medicine at a location inside the patient's respiratory system, the nebulizing catheter provides for increased efficiency and control of the dosage of medicine being delivered. In further aspects of the nebulizing catheter apparatus and method, alternative tip constructions, flow pulsation patterns, centering devices, sensing devices, and aspiration features afford greater efficiency and control of aerosolized medicine dosage delivery.

Granted: 1999-11-16
Abstract: 43 A system and method of measuring the linear and nonlinear response of an unknown acoustic termination uses a small probe assembly containing a sound source and microphone to determine the reflection function of the unknown acoustic termination. The probe assembly is used with a calibration tube to calculate an electrical signal that will provide a desired acoustic stimulus signal to the acoustic termination. The calibration tube is also used to characterize the signal processing properties of the sound source and microphone, as well as other associated signal processing circuits such as amplifiers, filters, and the like. The calibrated system is subsequently coupled to the unknown acoustic termination to deliver the acoustic stimulus signal. The reflection function is indicative of the power transferred to the unknown acoustic termination. The measurement of the linear transfer characteristic is applicable to any unknown acoustic termination such as a musical instrument or the auditory system. The probe assembly is sized to be positioned directly within the outer portion of the ear and measure the linear characteristics of the ear. The system is further able to measure the nonlinear transfer characteristics of the ear by measuring the linear response at multiple levels of the acoustic stimulus. The system is particularly useful in testing the response of the middle ear and inner ear of humans or other animals.

An injection nozzle in the female mould allows molten plastic to be injected into the mould cavity so that a preform moulded article may be formed. The neck ring is constituted by a pair of mating halves which can be separated laterally with respect to the longitudinal axis of the mould core. A taper sleeve surrounds the mould core beneath the neck ring. The neck ring halves are secured to diametrically opposed slides to facilitate lateral separation of the neck ring. A pair of slide taper locks contact a respective one of the slides to inhibit lateral movement of the slides and to back up the neck ring when injection mould is in a mould closed position. An annular formation is formed on the upper surface of the neck ring and is accommodated by a complementary recess formed in the bottom of the female mould. The mating inclined surfaces of the female mould and the annular formation constitute an upper taper lock which is backed up by a cavity plate. An annular formation is provided on the upper surface of the taper sleeve and is accommodated by a complimentary recess formed in the bottom of the neck ring. The mating inclined surfaces of the taper sleeve and neck ring constitute a lower taper lock. Since a portion of the neck ring constitutes the female taper of the lower taper lock, the lower taper lock is backed up by the slide taper locks through the slides allowing the cross-sectional area of the neck ring to be reduced.
