Patent CA-2285683-A1 (CA)
Title: Method and apparatus for controlling operation of a submersible pump
Inventor: GAMBER ROBERT M
IPC: F04D15/02
Filed: 1999-10-06
Abstract: A deep well pumping system includes a pump, a motor coupled to the pump and a control unit coupled to the motor. The control unit comprises a timer for measuring time. The system is configured to initiate a start sequence of the motor and determine whether a timer valve exceeds a first valid time range. If the timer valve exceeds the first valid time range, the system determines whether a motor frequency is less than or equal to a first valid frequency range. If the motor frequency is less than or equal to the first valid frequency range the system alters the signals applied to the motor. The system may be used to eliminate an obstruction from the pump.

Title: Memo holder
Inventor: HEEMBOCK PETER
IPC: G09F7/04
Filed: 1999-11-15
Abstract: A memo holder includes a magnetic sheet which is of a type commonly referred to as a "refrigerator magnet". The magnetic sheet may be of any shape, but should be sufficiently large to provide adequate support for the entire memo holder. A flashing arrow or other indicator device is supported by the magnetic sheet and includes a light source, such as a light emitting diode, and a replaceable battery power source. The indicator is switch operated, so that it can be turned on when a memo is present to attract attention, and turned off when no memo is present to avoid confusion and to save power. A clip allows the attachment of a small piece of paper such as the memo to the holder. A preferred clip is of the alligator jaw variety.

Title: Random peptides that bind to gastro-intestinal tract (git) transport receptors and related methods
Inventor: BELINKA BENJAMIN A JR
IPC: C12N1/21
Filed: 1998-05-15
Abstract: This invention relates to proteins (e.g., peptides) that are capable of facilitating transport of an active agent through a human or animal gastro-intestinal tissue, and derivatives (e.g., fragments) and analogs thereof, and nucleotide sequences coding for said proteins and derivatives. The proteins of the invention have use in facilitating transport of active agents from the lumenal side of the GIT into the systemic blood system, and/or in targeting active agents to the GIT. Thus, for example, by binding (covalently or noncovalently) a protein of the invention to an orally administered drug, the drug can be targeted to specific receptor sites or transport pathways which are known to operate in the human gastro-intestinal tract, thus facilitating its absorption into the systemic system.

Title: Antenna system
Inventor: GODARD JEFFREY ALLAN
IPC: H01P3/08
Filed: 1998-06-25
Abstract: An antenna system (10) that is particularly suited for use in communications systems implementing wireless local loops. In its preferred embodiment, the antenna comprises an array of air loaded stacked patch antenna elements (14a-14d) suspended above a ground plane (12). The antennas each operate in a dual slant (45) linearly polarized mode and are fed by air loaded microstrip transmission line feeds. The line widths of the feed lines are uniform throughout the design, thereby eliminating the need for impedance transformers. The electronics for the antenna is located beneath the antenna ground plane (12) to reduce the footprint of the antenna. In addition, a "connectorless" coupling structure is provided for transferring signals between the antenna elements (14a-14d) and the underlying electronics. In one embodiment, an antenna is provided having enhanced sidelobe suppression despite having a limited number of side by side elements in a plane of interest.

Abstract: An upper end (10) far the inner tube of a core drill has a hard ball (30) which runs in a circumferential track (24). The ball (30) and track (24) are adapted to be carried within a tubular upper end casing (12) which surrounds a spindle (11) which supports the inner tube of the drill. An indent washer 25 is positionable above the track (24) and ball (30) and is oriented relative to the casing. A spring (26) supports the washer (25) above the ball (30). When the upper end (10) is lifted, the ball (30) is driven into contact with the washer (25) and makes an impression. The orientation of the impression reveals the orientation of the lowest point in the track (24). The impressioned washer (25) can be used to assist in noting or marking the core orientation after the drill is removed from the earth.
Patent CA-2297634-A1 (CA)
Inventor: UMIJI KEITA
IPC: G01S7/62
Filed: 2000-02-02
Abstract: To extract a target object having a desired size from a bidimensonal image, horizontal direction filtering suppresses image components less than the desired size in the horizontal direction and thereby outputs a result of horizontal filtering. At the same time, vertical direction filtering suppresses image components less than the desired size in the vertical direction and thereby outputs a result of vertical filtering. The results of the horizontal and vertical filtering are superposed to produce a final filtered result corresponding to the target object. During the filtering, pixel data making up the bidimensonal image are sequentially connected in the vertical or horizontal direction in a preselected connecting area to produce gradation sequence of the pixels and then subjected to FFT to transform the gradation sequence into frequency domain and to thereby frequency selection to select desired harmonics components corresponding to the target object from the FFT result.

IPC: G11B7/0055
Filed: 1998-07-28
Abstract: A method for optimizing the interaction of a resonant material (90) having generalized crystal symmetry with a beam or beams of radiation (from emitters 210). The invention includes determining a special direction relative to the axes of crystal symmetry of the material and polarizing the interaction radiation beam along this direction. The polarized radiation beam (235) is propagated through the material perpendicular to this special direction. The method and system are used in any application which involves the coherent interaction of optical radiation beams or fields with resonant ion-doped or molecular crystals of various types. Coherent interaction of optical radiation beams or field with resonant ion-doped or molecular crystals of various types includes the phenomena of optical coherent transients, spectral hole burning, and spatial-spectral holography (also called time- and space-domain holography) and provides the basis for optical-electronic devices. Such applications include computers and communications networks.

IPC: G06T11/00
Filed: 2000-04-17
Abstract: In addition to widely spread bitmap types of images like JPEG or TIFF used to represent illustrations in World Wide Web pages this invention provides a simple way of creating vector, or outline type of images using existing features of Java-enabled browsers without introducing new image formats. The idea is to create a tool for the Web page developer that will take a vector graphical image and convert it into a set of Java drawing commands finally forming a Java applet. The client's browser then will display the applet in the Web page, as it would be a regular graphical image. The benefits of this method are higher image compression rate and scalability.
