Patent CA-2258516-A1 (CA)
Title: Conjugates of thrombin inhibitors and endogenes carriers
Inventor: SONG YONGHONG
IPC: A61K47/48
Filed: 1997-06-30
Abstract: Novel compounds comprising chemically reactive intermediates which can react with available reactive functionalities on blood components to form covalent linkages, where the resulting covalently-bound conjugates are found to have thrombin inhibition activity are provided. Specifically, the thrombin inhibitor compounds of the present invention are derivatives of the known thrombin inhibitor argatroban, which can be covalently linked to chemically reactive functionalities on various blood components. The conjugated thrombin inhibitors thereby have extended lifetimes in the blood stream, as compared to the unconjugated parent drug, and are, therefore, capable of maintaining thrombin inhibitory activity for extended periods to time as compared to the unconjugated parent drug. Also provided herein are methods for inhibiting thrombin activity in vivo comprising administering to the bloodstream of a mammalian host the novel compounds of the present invention.

Patent CA-2263422-A1 (CA)
Title: Antenna for nonterrestrial mobile telecommunication system
Inventor: RAY JIMMY CARROL
IPC: H04W84/06
Filed: 1997-08-25
Abstract: The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.

Title: A method of probing drill holes electromagnetically, and a transmitter arrangement and a receiver arrangement for carrying out the method
Inventor: EDERLOEV PER
IPC: G01V3/10
Filed: 1998-09-21
Abstract: The invention relates to a method and to a transmitter arrangement for the probing of drill holes (4). The transmitter includes a ground-located conductor loop (1) which is supplied with a current that has a wave shape which includes at least one low frequency (e.g. 200-3000 Hz). The frequency is crystal controlled and normalised to time signals from GPS satellites. The receiver includes coils which function to sense field changes having the same frequencies as the transmitter and is housed in the probe (6), said probe being lowered with the aid of a typical drill pipe (5) and lacks signal connection with the transmitter. Instead, the probe includes an accurate quartz clock which is frequently calibrated and which enables the phase of the received signal to be determined synthetically relative to the phase of the transmitter signal, e.g. by means of a signal processor. Because a typical drill rod is used, the drill hole may have any chosen direction and may even be blocked with sludge, slurry, etc., therewith obviating the risk of the probe becoming stuck in poor rock, as in the case of line-carried probes.

Patent CA-2288408-A1 (CA)
Title: Dynamic variation of class of service in a communication network based on network resources
Inventor: MARINHO JOHN A
IPC: H04L29/06
Filed: 1999-11-03
Abstract: A communication system monitors the resources that are available for new users. When the availability of free resources becomes too small or falls below a threshold, the communication system initiates a reduction in the the class of service to selected users. The class of service can be reduced by reducing the quality of service provided to existing communications or by providing selected new users with only lower quality communications. The decision to alter the class of service is alerted to the end user and based on the profile of the end user, appropriate alteration of a specific resource parameter is undertaken. The quality of communications may be reduced, for example, by decreasing the information carrying capacity of the channel available to a particular user and thereby decreasing the data transfer rate, decreasing the amount of error encoding used to detect and correct errors introduced by a communication channel, or in the case of a wireless system, using a lower rate vocoder (voice encoder) which will reduce the voice quality or clarity of the speech transmitted over the communication channel.
