Patent CA-2187343-A1 (CA)
Inventor: CARNEY RONALD R
IPC: H04J1/05
Filed: 1995-03-13
Abstract: A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, for wideband signal processing, together with a sample rate. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units, which process (e.g. demodulate) respective ones of the digital channel signals and supply processed ones of the digital channel signals at respective output ports for distribution to an attendant voice data network. On the transmit side, a transmit section contains a plurality of digital signal processors respectively associated with respective ones of a plurality of incoming (voice data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.

Patent CA-2193789-A1 (CA)
Title: Spherical mating fairings for hingeline applications
Inventor: KOPPELMAN H JOHN
IPC: B64C7/00
Filed: 1996-12-23
Abstract: The invention is an aircraft apparatus consisting of a two part hinge line fairing design for preventing physical interference between the two fairing parts while eliminating unacceptable gaps between the two fairing parts. The problems are made worse by the fact that the hinge line is not perpendicular to the longitudinal centerline of the fairing which is aligned with the airflow. The problems, such as gaps, are unsightly and also increase drag. These problems are solved by the use of two matching surfaces of the fairing having substantially the same curvature and radius in all directions. The slight difference in curvature, and radius, is appropriate to allow a smaller fairing part to extend into a larger fairing part for freedom of movement with respect to each other. Accordingly, the first of the two surfaces should have radii r1 equal to the distance from the hinge point D to the fairing surface, and the second of the two surfaces should preferably have radii r2 equal to the distance from the hinge point D to the second of the fairing surfaces plus approximately .15 inches or so to allow for clearance with the first fairing surface.

Patent CA-2196818-A1 (CA)
Inventor: GARREN DONALD LEE
IPC: F16L1/12
Filed: 1997-02-05
Abstract: The cable laying apparatus, which solves many of the problems heretofore associated with existing cable laying mechanisms for underwater burial machines, uses a pivotally liftable depressor wheel, located within a feed shoe which tracks the groove cut by the plow. There are a pair of arcuate cable guides, one on each side of the depressor wheel, which assist in the guidance of both cables and bodies, without permitting either to bind. When the assembly to which the depressor wheel is attached is raised upward and rearward the guides prevent the cable from escaping while allowing a body to pass through the opening which is formed.

Filed: 1997-05-29
Abstract: A method of preserving privacy in an electronic storage-and-retrieval message system includes providing access by designated persons to manipulating interface features for storage/retrieval information related to directing messages, while restricting access to any stored messages. In a voice mail system, the storage/retrieval interface feature includes the greetingthat is presented to a calling party. A first access code, such as a password, is assigned to enable access to the interface features, while a second access code is assigned to enable message-retrieval. In the preferred embodiment, changes to a greeting or the like are reported in an audit message that is stored in the user's mailbox. The audit message is automatically generated. The audit message notifies the user of the history of any changes. Changes to a greeting may also be automatically generating by using a stepped sequence of prompts to solicit information relating to the user. For example, in a voice mail system, the sequence may be a series of voice prompts requiring responses by depressing selected telephone keys. The method may be used with message systems that store messages in one or more forms of audio, video, textual and facsimile data.

Title: Shaped lignocellulosic-based activated carbon
Inventor: MILLER JAMES R
IPC: C01B32/384
Filed: 1997-09-18
Abstract: Extruded pellets comprising a majority of activated carbon particles and an organic binder provide improved performance when processed through tumbling equipment while the pellets are in their "green" state, i.e., pellets which are fresh off the extruder and contain activated carbon, binder, and water and have not been subjected to any thermal processing (drying). The tumbling action both smoothes the pellets (by closing any cracks and greatly improving appearance) and increases the density of the packed bed, e.g., by increasing particle density and reducing voids between the pellets. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of dust associated with the carbon, both the initial dust and the dust attrition.
Patent CA-2217586-A1 (CA)
Inventor: CONDON JOSEPH HENRY
IPC: H04L12/56
Filed: 1997-10-06
Abstract: This invention provides a fast framing device that processes a stream of bytes and generates a signal for every byte clock that indicates whether a selected Asychronous Transfer mode cell boundary may be valid. The fast framing device generates a Cyclical Redundancy Code (CRC) corresponding to each byte from a input byte stream.  The generated CRC is processed by an XOR tree that produces an output equivalent to processing the CRC code through five cycles of an CRC generator. The result of the XOR tree is exclusive with a hexidecimal number "AC" or 0xAC. The result of the XOR tree and the XOR gate is delayed by five cycles and then compared with the CRC generated during the fifth byte clock. The compared results indicates whether the prior five bytes may be a valid ATM cell header.
