Patent CA-2338289-A1 (CA)
Inventor: KRYGER DAVID L
IPC: G06F7/544
Filed: 2000-05-01
Abstract: A method and a device for high-speed scale conversion wherein a value N within a range of N1 and N2 is converted into a small value M within a range of M1 and M2. The method 5 includes the step of obtaining an approximate value of M  by loading the value (N-N1+2p-1) into a multi-bit shift register and right-shifting p bits. A binary search process is then used to determine the error value between the actual value of M and the approximate value of M. By avoiding actual multiplication processes, the conversion can be carried out using low-cost electronic hardware such as a microprocessor or a PROM to carry out the binary search process, a shift (10) register to obtain the approximate value of M, a multiplexer to receive an analog input data N and an A/D  converter to convert the analog input data N into a digital data N.

The cable communication system includes a head end Remote Digital Terminal (RDT) respectively communicating with a broadband network, a telephone switch and a customer premises Integrated Service Unit (ISU), and also includes an Order Management Center (OMC) associated with the RDT, the switch, or both. To implement telephone service to customer premises equipment adapted for communication with the ISU, the RDT is notified of a new service request by way of a service request message sent from the ISU to the RDT, and the switch is notified of the new service request by way of provisioning information sent from the OMC to the switch via an Element Management System (EMS) associated with the switch. Advantageously, the RDT and the switch are adapted exchange information needed to coordinate the provisioning of telephone service to the customer premises equipment. In a first embodiment, which is useful when the OMC and the switch are not owned by the same service provider, the service option information sent to the switch is initially provided to the OMC via an in-service telephone. In a second embodiment, which is useful when the OMC and the switch are co-owned, the service option information is initially provided to the OMC via a temporary telephone connection established between the customer premises equipment and the OMC.

Title: Periodicity enhancement in decoding wideband signals
Inventor: SALAMI REDWAN
IPC: H04Q7/32
Filed: 1999-10-27
Abstract: The present invention relates to a method and device for enhancing periodicity of an excitation signal produced in relation to a pitch codevector and an innovative codevector for supplying a signal synthesis filter in view of producing a synthesized wideband signal. In this periodicity enhancing device and method, a factor generator is responsive to the adaptive and innovative codevectors for calculating a periodicity factor. An innovation filter subsequently processes the innovative codevector in relation to this periodicity factor to reduce energy of a low frequency portion of the innovative codevector and enhance periodicity of a low frequency portion of the excitation signal. As an example, the innovation filter has a transfer function of the form: F(z)--.alpha.(z)+1-.alpha.(z)-1 where .alpha. is a periodicity factor, and the factor generator calculates the periodicity factor .alpha. using the relation:  .alpha. = qR p bounded by .alpha. < q where q is an enhancement factor set for example to 0.25, and where R p is represented by formula (I) where v~ is the pitch codevector, b is a pitch gain, N is a subframe length, and u is the excitation signal.

Title: Impermeable and composite perforating gun assembly components
Inventor: XU ZHENG RONG
IPC: E21B43/117
Filed: 2001-07-30
Abstract: A perforating gun assembly that includes at least one component that is constructed from a composite material and that is impermeable to wellbore fluids. The components may include the outer carrier and/or loading tube of a perforating gun, the connecting tubing of a gun release mechanism, and the gun connector used to attach adjacent perforating guns. The composite material is designed to be very brittle under dynamic impact. The component is made impermeable to wellbore fluids by including an impermeable liner therein. The impermeable liner can be bonded to the inner or outer surface of the component or can be embedded within the component. Since it is brittle under dynamic impact, the composite component shatters into small pieces upon detonation of the perforating gun.

Title: Ocular replacement apparatus and method of coupling a prosthesis to an implant
Inventor: GARONZIK SCOTT N
IPC: A61F2/14
Filed: 1999-12-29
Abstract: An ocular replacement system provides a ball-shaped implant body (20) having an outer spherical and porous surface (22) that is receptive to ingrowth of ocular tissue and including an anterior portion (24) positioned forwardly when the implant is fitted in the eye cavity (12) to create a convex tissue surface area when covered by conjunctiva (11).        A prosthesis (30) includes an outer face and an opposite inner concave surface (36) shaped to conform generally to the convex tissue surface area. When fitted in the front orbital space of the eye cavity (12) and a magnetic attractive force between at least one magnet (46) on the inner surface of the prosthesis. One or more magnetically attractive elements (42) on the anterior portion of the implant couples the prosthesis (30) to the implant (20) so that the prosthesis (30) follows movement of the implant to simulate natural eye movement within the eye cavity (12).        The magnets are offset relative to the attractive elements (42) to avoid direct alignment and excessive magnetic attraction, thereby reducing pressure which may cause tissue breakdown, infection, tissue dehiscence or implant extrusion.

Filed: 2000-04-27
Abstract: Cette invention se rapporte à un procédé amélioré permettant de transformer des argiles ne pouvant pas être utilisées dans la production de pigments commerciaux en pigments de faible viscosité, en vue d'une application commerciale. A cet effet, on produit une argile traitée ayant une viscosité réduite par rapport à l'argile initiale, lorsqu'on les compare en terme de teneur équivalente en matières solides. Ce procédé consiste: à faire sécher l'argile; à mélanger l'argile ainsi séchée à une solution aqueuse d'un sel de métal alcalin, lequel est choisi dans le groupe des sels de lithium, de potassium, de rubidium et de césium; à extruder le matériau obtenu du traitement du sel de métal alcalin; à traiter à chaud le matériau ainsi extrudé et à délayer sous cisaillement élevé le matériau ainsi traité à chaud. Généralement, une argile de viscosité élevée ayant été traitée avec ce procédé en cinq étapes va posséder une viscosité équivalant à environ 10 % - 20 % de la viscosité de l'argile de départ.
