Patent CA-2221969-C (CA)
Title: Mitigation of multipath effects in global positioning system receivers
Inventor: HATCH RONALD RAY
IPC: H04B1/709
Filed: 1996-05-24
Granted: 2007-08-07
Abstract: A technique for minimizing or eliminating the effect of multipath signals in a receiver processing pseudorandom (PRN) code signals, such as in a global positioning system (EPS) receiver. The presence of multipath signals adversely affects both code measurements and carrier phase measurements of received PRN signals. One aspect of the invention provides for improved code tracking in the presence of multipath signals, by sampling the received code with a multipath mitigation window (MMW) (FIG. 25D) that results in a code error function (FIG. 25F) that reduces or eliminates the multipath effects. The MMW, which may by any of a number of preferred waveforms (FIGS. 35b-35E), provides a code error function that varies in opposite directions from zero at a desired tracking point (402), but assumes a nearly zero value when the MMW is advanced from the tracking or synchronization point by more than a small fraction of a code chip. Because of this nearly zero code error value on the early side of the desired tracking point, delayed multipath signals will have a corresponding code error function that is nearly zero (FIG.  25F) at the desired tracking point of the directly received signals, and the multipath signals will, therefore, have little or no effect on the desired tracking point and on code synchronization. The effects of multipath signals on carrier phase measurements are minimized by sampling the received signals, together with their possible multipath components, before and immediately after code transitions (vectors A and B respectively). The vector relationship of the directly received (D) and multipath (M) signals is such that performing a vector average of the two types of samples (A  and B) produces the directly received signal (D) and its correct phase, with many, if not all, of the multipath components (M) eliminated.

Title: Dual thermal and ultraviolet curable powder coatings
Inventor: DALY ANDREW T
IPC: C09D5/03
Filed: 1997-12-22
Granted: 2001-04-24
Abstract: Opaquely pigmented or thick filmed powder coatings for heat sensitive substrates, such as wood, wood composites, for example, medium density fiber board, and plastics, that can be fully cured, especially near the substrate, through the incorporation of a dual cure system in the powder comprising a thermal initiator, such as a peroxide, along with a UV initiator. The UV initiator cures the surface, while the thermal initiator cures at the substrate. Surprisingly, virtually no pregelation occurs during the heated melt and flow out step prior to UV curing. Consequently, the hardened film finish formed on the surface exhibits exceptional smoothness which is comparable to that of traditional UV curable powders. The hardened film finish is also fully cured throughout and exhibits exceptional adhesion to the substrate which cannot be achieved with traditional UV curable powders that have been pigmented. Although the dual cure system includes a thermal aspect, these powder coatings are especially suited for coating heat sensitive substrates. The dual thermal and UV curable powders still cure at significantly lower temperatures and significantly faster rates than traditional heat curable powders to make them safe for coating heat sensitive substrates.

Abstract: A multichamber container must have certain characteristics in order to uniformly dispense the contents of each chamber from the container. The outer wall of the container and the inner divider web walls must have certain characteristics. The inner divider web walls must be highly flexible while the outer container wall must be less flexible.  The Deflective Force for the outer wall must be greater than the Deflective Force for the web walls. In addition, to alleviate the problem of suckback of air into the container chambers, the outer wall should exhibit a specific Retention Index. This is a measure of the outer wall to remain deflected after the removal of the deflecting force. The inner divider web wall will have a lower Retention Index than the outer wall. By the proper selection of outer wall and web walls, there can be uniform dispensing from the dispenser.

Abstract: Un paramètre de modem requis pour un dispositif de modem est stocké dans une mémoire pour chaque numéro de téléphone d'une destination de notification à l'avance sur la base de communications précédentes. À l'heure de la communication, un côté de réception est informé de l'exécution du protocole court par un signal QTSD, et de manière séquentielle un signal QINFO qui comprend le paramètre de modem est transmis. Puisque le paramètre du modem est reçu par le destinataire de la communication, les pré-protocoles tels que l'échange de paramètres, etc. sont raccourcis afin que le temps de communication puisse être raccourci. En outre, du fait que la transmission du paramètre du modem est répétée jusqu'à ce qu'il soit confirmé que la destination de communication reçoit le paramètre du modem, l'apparition d'erreurs de communication peut être évitée, afin que les pré-protocoles raccourcis puissent être exécutés de manière sûre.

Abstract: A strapping machine and method for applying flexible heat-sealable straps around objects includes a programmable control system that receives encoder and other signals from various sensors in the machine to regulate each strapping cycle.  A feed/tension unit provides primary tensioning of the strap about the object based on signals from the control system. A motor driven roller and a pinch roller in the feed/tension unit each providing separate encoder signals to the control system to assist the control system in advancing and retracting the strap during feed and tensioning sequences, respectively, and provide signals indicating an exact position of the strap. A secondary tension system provides a final high tensioning force on the strap. The control system can automatically adjust individual strapping cycles, including tensioning, to compensate for various size bundles and different types of objects. Thereafter, a sealing head heat seals the strap, and severs the sealed strap from the remaining strap coil. The control system can selectively disengage the secondary tensioning during individual strapping cycles for objects that could be damaged or deformed during such high tensioning.

Abstract: There is disclosed a one-piece ceramic terminal suitable for use for mounting an electrical conductor in insulated relation to a supporting wall of a heating assembly. The ceramic insulator has a central block adapted to pass through a central portion of an aperture in the supporting wall.      This aperture has two radially extending slots extending outwardly of the central portion. The ceramic terminal includes a first pair of diametrically opposed radially extending wings which are sized to pass through the radially extending slots in the aperture. The ceramic insulator has a second pair of diametrically opposed radially extending wings which are sized larger than the slots in the aperture so as to engage one surface of the supporting wall. Once the first set of wings pass through the aperture and corresponding slots, the ceramic insulator is rotated such that the second set of wings engage the other surface of the supporting wall so as to mount the insulator relative to the supporting wall. An electrical conductor passes through a central slot in the ceramic insulator and is bent to prevent the insulator from rotating relative to the aperture in the supporting wall and prevent disengagement insulator from the supporting wall.

Abstract: A complex spreading and/or scrambling code sequence ("scrambling code sequence") generation system uses a first complex code sequence having at least two components and a second complex code sequence having at least two components. The components of the first complex code sequence are respectively mixed with the corresponding components of the second complex code sequence to generate the complex scrambling code sequence. In doing so, an offset between the components of the complex scrambling code sequence is achieved for the same and/or different users. For example, the complex spreading code sequence generation system can use a long code generator which produces a long code sequence produced from the inner product of a code vector and a user mask. The long code sequence is provided to an I path and a Q path. To produce a complex long code sequence, the long code sequence on the Q path is delayed to produce a second long code sequence on the Q path or a Q component of the complex long code sequence. On the I path, the I  long code sequence or the I component of the complex long code sequence is multiplied with an I component of a short code sequence to produce the I component of the complex scrambling code sequence. On the Q path, the Q long code sequence is multiplied with a Q component of the short code sequence to produce the Q component of the complex scrambling code sequence. As such, the offset between the components of the complex scrambling code sequence between different and/or the same user is at least the period of the short code. The complex scrambling code sequence can be used for spreading, scrambling, de-spreading or de-scrambling an information signal.
