Patent CA-2217066-C (CA)
Inventor: ERISMAN DAVID E
IPC: H04L27/20
Filed: 1995-04-10
Granted: 2001-06-19
Abstract: A digital modulation technique is disclosed which is unique in that it does not utilize fixed time slots for varying the characteristics of an electromagnetic carrier signal, but actually uses variations of the time slots to transfer the digital information.  The modulation is created by using direct digital synthesis techniques (10) to produce a carrier waveform (21) that closely approximates a sine wave carrier signal that can vary the time it takes for each peak to occur. The peaks of the carrier (21) are tightly controlled to occur at exact discrete time slots that correspond to certain base band digital data. The time slot changes occur precisely at the sine wave peaks to minimize the bandwidth requirement and maximise the data rate.

Title: System for increasing a value of an electronic payment card
Inventor: CHEUNG WING KEUNG
IPC: G07F7/08
Filed: 1997-10-30
Granted: 2000-12-05
Abstract: A system for increasing the value of an electronic payment cards is described. The system comprises a security module, amongst others, arranged for authentication of the card and authorizing means for authorizing a value increase transaction of the card. The system is arranged for sending a value increase message to the card, upon which the value stored in the card's memory is increased, if the card has been found authentic and the value increase transaction thereof has been authorized. The system comprises also storage means, in which identification data of the card are stored and linked thereto data relating to the authorization of the value increase of the card. If a value increase transaction is interrupted after authorization for the transaction had been given, a restore transaction is carried out. In the restore transaction it is checked if the card is authentic and the value increase transaction is carried out on basis on the authorization information stored during the value increase transaction. So, with the system according to the present invention, interrupted value increase transactions may be recovered without the need for a new authorization.
Patent CA-2226530-C (CA)
Inventor: DALRYMPLE LARRY V
IPC: H01B7/16
Filed: 1998-01-08
Granted: 2008-03-25
Abstract: Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing. The void spaces between the insulator and the tubing inside wall can be filled with a sealing material. Alternatively, the voids around the substantially centralized conduc-tors can be used as flow channels for the transmission of fluid pressure to a remote location, such as downhole. The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.

Title: Methods for identifying service processing of telephone calls
Inventor: CHEN JIN-SHI
IPC: H04Q3/66
Filed: 1998-02-05
Granted: 2001-08-07
Abstract: The present invention comprises methods for efficiently identifying international outbound calls, in the telecommunications network (TN) of the outgoing country, which should be screened as possibly requiring processing according to a Global Virtual Network Service (GVNS), as opposed to conventionalinternational long distance (ILD) call processing. In particular, the present invention is directed to outbound international GVNS calls, known as "on-net," which are from one GVNS location to another GVNS location of the same customer. International calls that are not Outbound International GVNS On-net calls, referred to as Other ILD calls, include at least three types: standard ILD, non-GVNS data and international GVNS off--net calls. Standard ILD, non-GVNS datacalls and international GVNS off--net calls all have a routing number which comprises a country code (CC) followed by a national number (NN). In the presentinvention, all Outbound International GVNS On-net calls have a routing number which begins with a CC followed by a country code suffix (CC-suffix). Therefore,the presence of a CC-suffix after the CC in a call routing number indicates that the call should be screened as being, possibly, an Outbound International GVNS On-net call.

Title: Method and apparatus for synchronizing signals
Inventor: KUPNICKI RICHARD A
IPC: H04N5/073
Filed: 1998-05-29
Granted: 2004-01-20
Abstract: A method and apparatus for synchronizing unrelated reference signals originating from two or more sources at different locations, which signals may be in different signal formats and/or subject to different delays at the receiving station. A master generator having an absolute time input from a highly stable time source generates a master reference signal having a frequency that is a common multiple of the frequencies of the unrelated reference signals. A counter is implemented from an arbitrary initial time point and the time elapsed from the initial time point to a synchronizing event is periodically encoded into the master reference signal as time code data. A slave generator associated with each information signal is genlocked to the master reference signal, and the time code data is encoded into the slave reference outputs. Each synchronizing event is thus associated with time code data specifying the absolute time of the synchronizing event, which can be inserted into an upstream position in the slave reference output associated with the information signal. Thus, two signals originating from different locations can be precisely synchronized so that transmission from one source to the other is synchronous and signal timings are known in advance.

The photodetector has multiple layers of materials including at least one quantum dot layer between an emitter layer and a collector layer, with a barrier layer between the quantum dot layer and the emitter layer, and another barrier layer between the quantum dot layer and the collector.

Abstract: Potato plants which exhibit reduced levels of a glucan L-type tuber phosphorylase (GLTP) or a glucan H-type tuber phosphorylase (GHTP) enzyme activity within the potato tuber are provided. The conversion of starches to sugars in potato tubers, particularly when stored at temperatures below 7 ° C, is reduced in tubers exhibiting reduced GLTP or GHTP enzyme activity. Reducing cold-sweetening in potatoes allows for potato storage at cooler temperatures, resulting in prolonged dormancy, reduced incidence of disease, and increased storage life. Methods for producing potato plants which produce tubers exhibiting reduced GLTP or GHTP enzyme activity are also provided. Reduction of GLTP or GHTP activity within the potato tuber may be accomplished by such techniques as suppression of gene expression using homologous antisense RNA, the use of co-suppression, regulatory silencing sequences, chemical and protein inhibitors, or the use of site-directed mutagenesis or the isolation of alternative alleles to obtain GLTP or GHTP variants with reduced starch affinity or activity.

Abstract: A discontinuous lignocellulose fiber is described for use as a reinforcing filler for thermoplastic composite compositions. The fiber filler includes a significant percentage by weight of long, "hair-like" fibers. Specifically, at least about 20 percent by weight of the fiber filler is discontinuous lignocellulose fiber with a fiber length greater than about 15 millimeters and a fiber diameter less than about 0.5 millimeters. A moldable thermoplastic composite composition including the discontinuous lignocellulose fiber comprises about 20 to about 50 percent by weight of the fiber filler and about 50 to about 80 percent by weight thermoplastic. The discontinuous lignocellulose fiber filler yields thermoplastic composite compositions having improved physical properties over basic thermoplastic. The improved physical properties can be achieved without the use of coupling agents, although coupling agents may be used to further enhance the composite properties. The discontinuous lignocellulose fiber is preferably derived from virgin, waste wood from either softwood or hardwood tree species depending on the end use of the composite composition. The thermoplastic can be selected from a number of post-consumer or post-industrial waste sources. Processes for the manufacture of the discontinuous lignocellulose fiber reinforcing filler and the thermoplastic composite compositions are also disclosed.
