Patent CA-2303875-A1 (CA)
Inventor: RASKINSKI JOHN E
IPC: G01S17/86
Filed: 1998-09-24
Abstract: A dual radio frequency interferometer aided by laser rangefinder and terrain database system utilizes two linear rays of RFI sensors to determine the position of a source of RF energy. The dual RFI system is very attractive in that it is a passive system and cannot be detected by other sensors or systems while it is going through its position determination operation. Furthermore, use of two linear arrays of sensors allows for the elimination of chronic effects inherent in radio frequency interferometers. The two linear arrays can be placed anywhere on a vehicle as long as they are in the same common geometric plane and in-flight mechanisms are provided to transform the coordinate systems from the in-flight platform coordinates to the local geodetic coordinates. This provides positioning and source identification which can be beneficial to not only the present system but other systems in the area. With the two linear arrays, a line-of-sight vector can be determined and other systems can be provided with this information in order to provide further details of the source position. Once a pointing vector has been determined, this information can be used with other active systems in order to provide a precise range and location of the source of the RF signals.

IPC: H04L1/20
Filed: 1998-10-09
Abstract: A system and method in a radio telecommunications network for correlating speech quality over an air interface link with a plurality of radio quality parameters. The system includes a mobile switching center (MSC) (13) for recording uplink radio quality information from the air interface link, a mobile test tool (12) for recording downlink radio quality information from the air interface link, a parser (16) for parsing the radio quality information into the plurality of radio quality parameters, and a memory (17) for storing the parsed radio quality information. A digital audio tape (DAT) recorder (19) or personal computer (PC) is electronically connected to a mobile station for recording a speech conversation from the air interface link simultaneously with the recording of the radio quality information. A DAT-link interface (21) is utilized to interface the DAT recorder with a playback unit(26)and with a synchronizer/controller (22) which synchronizes the stored radio quality information and the stored speech conversation. The radio quality parameters are presented to the operator in graphical form on a visual display (51) while the speech conversation is simultaneously presented to the operator in audio form (25). The operator enters a subjective evaluation of the speech quality of the speech conversation, and the evaluation is correlated with the radio quality parameters and displayed on the visual display.

Inventor: MONTELEONE KEITH JAMES
IPC: H04J3/06
Filed: 2000-04-19
Abstract: A method and apparatus for controlling bit slips in a high-speed, two-way, communications channel. More particularly, the entire communications system, comprising, inter alia., a receiver, a transmitter and the physical communications channel is operated as a feedback loop. That is, the detection of bit slips is performed continuously in the receiver and a bit slip signal is generated that indicates the number of bit slips and the direction, i.e., forward or backward, of the bit slip. Thus, the bit slip signal is communicated to the transmitter and certain actions are performed to introduce bit adjustments in the bit stream to eliminate the effects of any future bit slips. The bit slip signal contains an indication of the number of bit slips which have occurred, the time between bit slips, and the direction of the slip. As a function of this information from the bit slip signal, bit adjustments are made in the communications stream to correct for the bit slips and mitigate any effect in future transmission. For example, such bit adjustments include adding bits to particular data words in the bit stream or repositioning pointers used to traverse the data stream.
Patent CA-2307265-A1 (CA)
Title: Method and apparatus for a display producing a fixed set of images
Inventor: PREAS BRYAN T
IPC: G09G3/04
Filed: 2000-05-01
Abstract: A method to greatly simplify and reduce the cost of displays when all of the images that need to be displayed are known beforehand. By precomputing the intersections of the images and addressing the intersections of the images, the number of drivers that are required becomes a function of the number of images rather than a function of the resolution. For example, four arbitrarily complex, overlapping images require, at most, 16 drivers. In general, n arbitrarily complex, overlapping images require, at most, 2" drivers. This result holds irrespective of the size of the display or the complexity resolution, or amount of overlap of the images. Further reduction of the number of drivers is possible if some of the images do not overlap some of the other images. For example, two images overlap each other in one area and two other images may overlap each other in a separate area while the two sets of images do not themselves overlap. In this case, at most eight drivers are needed instead of the 16 drivers that would be required if all four of the images overlapped each other. In general, if you consider N separate, distinct areas, each with a set of overlapping images where ni images overlap in area i (ie, ni images that overlap in area 1, n2 images that overlap in area 2, etc.). Then the maximum number of drivers that are required will be summation for i from 1 to N of 2 raised to the power of ni.

Abstract: A method of stacking seismic traces including the steps of: deriving a representation of the noise component of each of the seismic traces; deriving an indication of the correlation between the noise components from the representations of the noise components; and producing a stacked seismic trace by combining the seismic traces in proportions derived from the correlation indications. The method can be used to produce stacked seismic traces having improved signal-to-noise ratios compared to conventionally stacked seismic traces. The preferred embodiment of this method is sometimes referred to as "covariant" stacking, because the weighting factors derived depend on the covariance of the noise components of their constituent traces.
