Patent CA-2613994-A1 (CA)
Inventor: VAN JONATHAN
IPC: B32B38/04
Filed: 2006-05-31
Abstract: The present invention describes a blade assembly for use with side-sealing and lap-sealing machines, which are used to seal thermoplastic film. Briefly, the cutting element is oval in shape, and has its entire outer edge profiled. This provides four distinct cutting surfaces, depending on the mounting orientation of the cutting element in the machine. This cutting element is held against a heating block, and its temperature is continuously monitored by' a temperature sensor. The sensor is spring-loaded to insure solid contact with the cutting element, and thus, accurate temperature measurements. This entire assembly is then encased in insulation. Additionally, the cutting element is mounted on an adjustable platform, which permits vertical adjustments relative to the film.  Thus, the specific portion of the cutting element which actually engages the film can be adjusted to improve the cutting quality or further extend the useful life of the cutting element.

Patent CA-2623868-A1 (CA)
Inventor: WALTER BRUNO H
IPC: F15B21/12
Filed: 2005-09-27
Abstract: A system (10) for generating high pressure pulses has a source (12, 16) of a pressurized working fluid (14). The working fluid is supplied to two conduits (22,24). A valve (26) has an input connected to each of the conduits (22, 24).  The valve has a valve member (29) that is movable between two positions. In one position the valve member allows working fluid to flow from the first conduit (22) to an outlet and blocks the second conduit (24). In the other position the valve member allows working fluid to flow from the first conduit (22) to the outlet and blocks the first conduit (22). Flow of the working fluid causes the valve member to reciprocate and thereby generate water hammers in conduits (22) and (24). Energy from the water hammers may be harnessed for various applications.

Title: Fault protection system and method for an electrical power distribution system
Inventor: STASZESKY DOUGLAS M
IPC: H02H7/30
Filed: 2006-10-03
Abstract: A fault protection system for an electrical power distribution system and a method of configuring and operating a fault protection system for an electrical power distribution system accepts device fault protection parameters, such as the time-current-characteristics (TCCs), of boundary devices, and selects and sets fault protection parameters for one or more fault protection devices, such as fault-interrupters, that thus coordinate with the boundary devices. Fault protection parameter selection for each fault protection device may occur automatically, and each device may reconfigure its fault protection parameters based upon changes in the electrical power distribution system, for example, as the result of fault isolation and/or service restoration.

Patent CA-2628002-A1 (CA)
Inventor: LEICHLITER SHAWN L
IPC: H03K17/687
Filed: 2002-07-03
Abstract: An apparatus in an electronic control system allows two or three wire operations. A power supply (150) can supply power to the enclosed circuitry in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two and three wire installations. Both zero cross detectors (110) are monitored and are used to automatically configure the electronic control. Over voltage circuitry senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuitry senses when the current through the MOSFETs has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuitry (120) is employed to keep the protection circuitry in effect even after a fault condition has cleared. Lockout circuitry (130) is used to prevent one protection circuit from tripping after the other circuit has already tripped from a fault condition. The protection circuitry output is desirably configured such that it can bypass and override the normal turn on and turn off impedance and act virtually directly on the gates of the MOSFETs. Preferably, the system has a high efficiency switching type power supply in parallel with a low frequency controllably conductive device.
Patent CA-2628942-A1 (CA)
Inventor: FREEMAN IAN BLAIR
IPC: G06F11/00
Filed: 2006-11-10
Abstract: Various apparatus and related methods are disclosed that are capable of detecting surface defects on an optical storage media. One example of an apparatus is configured to direct at least one light signal, which may be from one or more lasers, on an outer surface of an optical storage medium, such as a CD, DVD or the like, which includes encoded data. The light encounters both the optical storage media surface as well as any smudges, scratches, dents, or other defects thereon. Some or all of the light reflected from the defects and the surface are detected by one or more detectors, which may be a photodiode.  The detector(s) produce an output signal commensurate with the detected reflected light, which output is processed to determine whether the encoded data may be accurately read from the optical storage media.

Abstract: The system provides an Internet-based site accessible by customers and broadcasters for tracking the airing of their advertisements. The system includes a software package for creating a database of all events occurring on a broadcast station, which may comprise, for example, a radio or television station, although these are not intended as limitations. The software package receives a recording of a station's output, which contains metadata on each broadcast element that includes time, date, and content information. As the broadcast proceeds, the start and stop time of each element are stored in a table in the database. This database can then be subsequently queried via the website by a customer or media personnel to ascertain that the spot has aired as intended.

Filed: 2006-11-13
Abstract: A clamp apparatus for selectively occluding a resilient tube to prevent free flow of fluid in the tube comprises a base member to which the resilient IV tube is attached or through which it passes, and a slide clamp that slides relative to the base member and the tube. An aperture in the slide clamp has a relatively open hole at one end, through which the tube passes when the slide clamp is an open position, allowing fluid to flow through the tube. The aperture has a relatively constricted slot at the other end, through which the tube passes when the slide clamp is in the occluding position, preventing fluid flow through the tube. The apparatus serves to automatically and positively occlude an IV tube and maintain the IV tube in an occluded state.

Abstract: A security camera system according to present invention embodiments includes a telephoto type lens with one or more factors of optical zoom. A set of prisms that steer incoming beams from the surrounding environment (to adjust the field of view) is disposed in front, of the lens. The security camera system preferably includes a wide angle staring mode that encompasses a large field of view, where the prisms are oriented to provide no steering effect. The security camera system further includes a high-resolution zoom mode, where the telephoto lens focuses on a region of interest and the prisms perform beam steering to adjust the field of view and enable the region of interest or an object to remain at the center of the security camera system view. Image processing techniques may be employed that consider the beam steering angle and the field of view to compensate for distortion effects.

Inventor: LADVA HEMANT K J
IPC: E21B49/00
Filed: 2008-12-15
Abstract: The use of time-lapsed NMR diffusivity measurements in an observation well is disclosed.  The observation well is cased in the zone of interest with non-magnetic and non-conductive casing that is invisible to the NMR tool. Second, because NMR measurements have a dead zone in front of the antenna depending on the spatial variation of the fixed magnet strength, for example about 2.7 inches, a distance between the casing and the formation is reduced to less than the dead zone length by drilling the observation well at small deviation of about 5°  and running the casing without centralizers. Both the casing and the pad-type NMR tool will follow the low side of the borehole, ensuring the measurement volume of the NMR tool is inside the formation and beyond the annulus. With the appropriate observation well completion, time-lapse diffusivity measurements with pad-type NMR tools can address several shortcomings in the current practice of monitoring EOR processes that rely upon changes in density and hydrogen index (HI). Various uses of NMR imaging in wells cased with non-metallic casing are also disclosed.
