Patent CA-2271969-A1 (CA)
Inventor: GADSBY ELIZABETH DEIBLER
IPC: B01J47/14
Filed: 1997-12-05
Abstract: A method of monitoring the removal by a filter medium of a target substance from a liquid passing through the filter medium. The method involves: providing an indicator means; providing a filter medium having a plurality of binding sites which have a first affinity for the target substance and a second affinity for the indicator means; introducing the indicator means into the liquid; passing the liquid through the filter medium; and determining the presence or absence of the indicator means in the liquid which has passed through the filter medium. The first and second affinities are adapted to require binding of the indicator means by the filter medium only so long as binding sites are available to the target substance. Thus, the indicator means is adapted to compete with the target substance. As a practical matter, the liquid typically will be water. The indicator means may denote when the filter medium is not effective by altering the taste of the water passing through the filter medium. Alternatively, the indicator means may denote when the filter medium is not effective by altering the color of the water passing through the filter medium. For example, the indicator means may impart a color to the water passing through the filter medium.

Title: Pressure impulse telemetry apparatus and method
Inventor: POOL CHARLES M
IPC: H04H60/31
Filed: 1998-04-07
Abstract: An apparatus and method of communicating in a tubular system through a media disposed therein and actuating a controllable device are disclosed. The apparatus and method utilize a transmission apparatus at a transmission node that is in communication with the media. The transmission apparatus generates pressure impulses that are propagated through the media. The pressure impulses may be either positive or negative pressure impulses depending upon the selected transmission apparatus. The pressure impulses are detected by a reception apparatus at a reception node. The detection apparatus may detect the pressure impulses as variation in the media or as variation in the tubular system caused by the pressure impulses.      Once the detection apparatus has detected the appropriate pressure impulse or pattern of pressure impulses, a signal may be generated to actuate the controllable device.

Title: Harvesting platform with non-binding reel mount
Inventor: STIVERS MICHELLE LYNN
IPC: A01D57/02
Filed: 1999-12-15
Abstract: A non-binding reel mount for a harvester platform includes added clearance between the sidewalls of a reel mounting bracket and the reel lifting arms.  Side bushings are provided between the brackets and the arms at the center of the arms to prevent lateral motion of the brackets relative to the arms but enable twisting or rotation of the brackets relative to the arms. The non-binding reel mount thus enables one lift cylinder to be fully extended without causing binding between the reel mounting brackets and the reel support arms during a cylinder charging operation. The reel mount can be designed to provide the desired amount of vertical adjustment to the reel. In an alternative embodiment, a single bushing is provided at the top of the support arm that extends between the two sidewalk of the mounting bracket and wraps around the upper corners of the support arm to prevent lateral shifting while permitting rotation of the mounting bracket on the support arm.
Patent CA-2293173-A1 (CA)
Inventor: BROWN MATTHEW D
IPC: H03L7/18
Filed: 1999-12-29
Abstract: The proposed invention provides a method for filtering out the phase noise or jitter within a data stream that may be of any arbitrary rate. By using a synthesiser to convert a signal at the output of voltage controlled crystal oscillator (VCXO) to a signal with frequency similar to a desired high speed output rate, a limitation normally caused by the narrow tuning range of a VCXO can be overcome. Conversely, the desired high speed output rate may be converted to one similar to the VCXO frequency.

Title: Browser for hierarchical structures
Inventor: EBERT PETER
IPC: G06F17/30
Filed: 1998-08-19
Abstract: A browser for viewing data representing text, pictures, sounds, virtual reality worlds, links, or other objects, and organized in a hierarchical structure is provided to display and interact with links to the data. A retrieved set of data is displayed in a lens, and subsequently retrieved sets of data that are deeper in the hierarchical structure are displayed in further stacked lenses, creating a visual representation of the hierarchy. A label on each lens provides information on the data originally displayed in the lens. A user may choose to view the originally displayed contents of any lens on the screen. A user may also modify a personal hierarchical data structure comprising links to sets of data in the first hierarchical structure. In doing so, a user creates an entirely new hierarchical structure that customizes the organization of data according to personal preferences and takes advantage of natural association to reduce the number of perceived levels in the new hierarchical data structure.

Title: System and method for automatically muting restricted electronic devices in restricted areas
Inventor: LIPOVSKI G JACK
IPC: H04W4/90
Filed: 2000-05-25
Abstract: A system, consisting of an ultrasonic transmitter and a receiver, is described for controlling certain electronic sound-generating and radio-frequency-generating devices. In restricted areas where the audible sound generated by these electronic devices is objectionable, one or more ultrasonic transmitters are placed to blanket the area, each emitting an ultrasonic signal periodically. In electronic devices having ultrasonic receivers, the receipt of this signal prevents the electronic device from generating or reproducing objectionable audible sound for a short period of time after receipt of this ultrasonic signal, which is slightly longer than the period in which the ultrasonic signal is sent. Alternatively, an objectionable radio transmission can be inhibited. As long as an individual is in a restricted area, his or her electronic device will be automatically muted. After leaving such an area, the receiver will not detect the ultrasonic signal, and will function normally. Alternatively, ultrasonic transmitters are placed at entrances and exits. As an electronic device is brought into a restricted area through an entrance, it is muted, but when it passes through an exit, it reverts to a non-muted state. Thirdly, ultrasonic transmitters, placed at entrances to restricted areas will activate a timer for a time predetermined to be when the restricted device is in the restricted area; while the timer is active, the device is muted.      Therefore, while an electronic device is in the restricted area, it is muted. This apparatus can optionally be enhanced with a communication channel to configure and enable the ultrasonic transmitters, and a communication channel to restore a device to its non-muted state when the ultrasonic transmitter fails to do so.
