Patent CA-2273661-A1 (CA)
Inventor: LEGARE CHRISTIAN
IPC: H04M3/32
Filed: 1999-06-07
Abstract: A method and apparatus for measuring transmission line parameters, such as the post-dial delay, the line rate, the near-end and far-end echo level, the noise level and the signal level, among others. The dedicated measuring device connects to a non-dedicated data terminal over a voice transmission line and, through the exchange of control signals with the data terminal, implements a test and measurement system that derives the various parameter measurements of the transmission line. Once all required parameter measurements have been determined, the measuring device disables the connection with the data terminal without engaging in a user payload data exchange with the data terminal.

Inventor: VAN DER MERWE CHARMAINE
IPC: C22B3/08
Filed: 1997-03-03
Abstract: A process is provided for the leaching of copper from chalcopyrite using ferric sulphate in which acceptable rates of leaching are achieved by controlling the surface potential of the chalcopyrite to an empirically determined "window" within the broad range of 350 to 450 mV. The most effective process conditions involve the selection of the said surface potential; the leach temperature; the pH of the leach solution; and the fineness of the grind of the chalcopyrite. The invention may be applied to both tank leaching and heap leaching processes.

Title: Method of scoring a video wagering game
Inventor: YOSELOFF MARK L
IPC: G07F17/32
Filed: 1998-03-11
Abstract: A method of scoring a video wagering game is disclosed. The method includes placing a wager to participate in a video wagering game, and playing a first segment of the game. The first segment is played until a set of predetermined conditions has been met. A payout value (162) is assigned to a winning outcome of the first segment. When the predetermined conditions have been met, the player plays a second segment of the game. The outcome of the second segment determines a factor (158) that is at least equal to one. The payout value assigned to the first segment is multiplied by the factor to determine the game payout (173).

Title: Method and apparatus for reducing signal processing requirements for transmitting packet-based data with a modem
Inventor: PETERSON KEVIN H
IPC: H04L29/00
Filed: 1998-05-08
Abstract: A modem and method for operating same. A receiver circuit of the modem is coupled to receive a continuous analog signal from a communication channel.  This analog signal includes both packet and idle information. The receiver circuit monitors the analog signal to detect the presence of idle information.  Upon detecting idle information, the receiver circuit enters a standby mode in which the processing requirements of the receiver circuit are reduced. A burst mode protocol is also provided, in which packets of digital information are modulated by a transmitter circuit of the modem, thereby converting the packets of digital information into analog signal bursts of discrete duration.  These analog signal bursts are transmitted from the transmitter circuit to a telephone line. However, the transmitter circuit does not generate any signals between the analog signal bursts. A receiver circuit monitors the telephone line to detect the analog signal bursts. Upon detecting the presence of the analog signal bursts on the telephone line, the receiver circuit demodulates the analog signal bursts using full processing capabilities of the receiver circuit. However, upon detecting the absence of the analog signal bursts on the telephone line, the demodulating function of the receiver circuit is disabled. The burst mode protocol enables multi-drop and multi-cast operation, as well as reducing required DSP resources.

Title: Method of making downlink operational measurements in a wireless communication system
Inventor: SOLONDZ MAX AARON
IPC: H04B17/40
Filed: 2000-02-07
Abstract: In the method of making downlink operational measurements a measurement request from one of a main controller and a first base station is sent to at least a second base station. The measurement request requests the second base station to instruct mobile terminals in communication therewith to make operation measurements of at least one signal transmitted by the first base station. The second base station transmits a measurement instruction to the mobile terminals in communication therewith in response to the measurement request. The measurement instruction instructs the mobile terminals in communication with the second base station to make operational measurements of the signal transmitted from the first base station. Then the second base station receives results of the operational measurements from the mobile terminals in communication therewith Alternatively or in addition, the second base station makes the operational measurements.

Title: Cable bolt with a yielding fixture and method of forming the same
Inventor: LAUSCH PETER
IPC: F16G11/02
Filed: 2000-03-15
Abstract: A cable bolt comprises a cable with a tubular yielding fixture at one of its ends. The pull-off load of such yielding fixture can be adjusted to a desired value. This is achieved by unwinding one end of the cable and inserting a slug over the kingwire. Then, the peripheral wires are wound again over the kingwire forming a bulge in the cable where the slug is located. The yielding fixture is then slid on the cable and forced over the bulged portion of the cable, while measuring the load required to achieve this operation, which also becomes the pull-off load of the yielding fixture. Finally, any part of the cable protruding from the fixture is cut-off to form the cable bolt with the desired yielding fixture at its end.

Title: Stapler with feed system for elements to be stapled to a workpiece
Inventor: STEED WILLIAM G
IPC: B25C5/06
Filed: 2000-04-20
Abstract: A stapler with a tab magazine includes a staple magazine parallel to a workpiece surface, a staple driving head and a pneumatic or electric drive for effecting a forwarding movement of the staple driver head in a direction substantially at right angles to the workpiece surface to a stapling position on the workpiece surface such that a staple from the magazine is driven into the workpiece. The driver head is controlled by a trigger and supply circuit. A tab magazine is provided along side the tab driver head for receiving a plurality of substantially planar, separate tabs in a stack of the tabs arranged each on top of the next. The magazine is arranged to support the stack in a direction generally parallel to the movement of the driver head and at a position to one side of the driver head. A spring feeds the tabs forwardly of the magazine to a forwardmost position. A drive lever pivots in a plane parallel to the surface to move a tab at the forwardmost position to the stapling position such that the staple passes through the tab at the stapling position to fasten the tab to the workpiece. The lever is driven at a timed relation relative to the driving action of the previous tab so that the next tab is held in a station at the stapling position ready to receive the staple and act as a reinforcement therefor to prevent pulling through a wrapping material. In another arrangement, the tab magazine is replaced by a roll of fiber reinforced tape so that a complete strip of tape underlies the staples and they all can be removed in a single pulling action. The strip or tabs act to locate a bag or wrapping on an article such as a stack of lumber.

Filed: 1998-11-06
Abstract: Conjugates are prepared from RGD containing peptides, by combining said peptides or analog with a material providing a functionally reactive group capable of reacting with a blood component (preferably a mobile blood cell or endogenous protein). The conjugates may be administered to patients to provide antiplatelet or antiadhesion properties through the inhibition of the binding of fibrinogen to the GPIIb/IIIa receptor, and may also be used as probes for receptor activity. The administration to the patient may be made either in vivo or ex vivo and may be performed by either introducing the RDG containing peptide including the reactive functional group into the patient's vascular system or preparing such a conjugate externally and introducing that conjugate to the patient's vascular system.
