Patent CA-2301670-A1 (CA)
Inventor: CABELL DAVID WILLIAM
IPC: A61K8/06
Filed: 1998-08-07
Abstract: A wipe comprising a high internal phase inverse emulsion disposed in a discontinuous pattern on a substrate. The pattern provides areas coated with the emulsion and areas free of the emulsion. Preferably the emulsion is disposed so that the surface area to volume ratio of the emulsion is minimized. The emulsion locally expresses water during use upon the application of pressure to the wipe. The water is useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.

IPC: F25D13/06
Filed: 1998-08-26
Abstract: A method of cooling baked products, such as bread, is provided comprising the steps of moving the products on a conveyor belt through a cooling unit, cooling air to about 15 ~C or less, thereby increasing its relative humidity, and then passing the cold air over the baked products to cool the products, the cooling coils in the cooling unit being arranged such that the temperature of the air does not rise by more than 8 ~C as it passes over the product s. Air having a temperature of about 15 ~C or less has a much higher relative humidity than air at ambient temperatures. Thus by passing such cold air over the baked products, the moisture loss from the products can be controlled without the use of humidification devices, such as air washers. This reduces the cost of the equipment needed, reduces cooling times, and is safer.

Abstract: To reduce processing load, FIG. 9 is representative of a filter configuration of the present invention. Essentially, a receive (460) and/or transmit (455) chain contains a multl-rate filter (456, 462) configured as a decimator or interpolator, respectively. In use, the multi-rate filter (456, 462) provides approximation of a desired impulse frequency response characteristic: (e g. root-raised cosine) within a radio frequency signal processing chain The multi-rate filter (456, 462) may be cocatenated (in series) with a conventional FIR filter (458, 464), such that the respective falters provide an anti-alias function and a band-pass function having well-defined impulse response characteristics. Signals either incident to a multi rate interpolator or exiting from a multi-rate decimator are at about a factor of three times the symbol/chip rate and preferably at about twice the symbol/chip rate. Consequently. the FIR filter (458, 464) operates at a low sampling rate with respect to the multi-rate filter, with the FIR filter provide RRC (or other desired characteristic) spectral shaping.

Title: A decoding method, speech coding processing unit and a network element
Inventor: VAINIO JANNE
IPC: G10L19/16
Filed: 1999-02-09
Abstract: This invention is related to tandem free operation (TFO) in mobile cellular systems. The present invention implements a tandem free operation by using a special feedback loop which makes the decoded parameters available, performs the comfort noise insertion and bad frame handling operations, produces the parameter quantisation indices corresponding to the output of these operations, and synchronises the speech encoders and the speech decoders in the transmission path from the uplink mobile station to the downlink mobile station. This functionality is realized by partly decoding and re-encoding the parameters and synchronising and resetting the quantiser prediction memories in a specific manner. A basic idea of the invention is, that during BFH and CNI processes, a re-encoding block produces models of encoded speech parameters from the BFH/CNI processed speech parameters. These models of encoded speech parameters are then transmitted to the receiving end. The present invention provides a solution to the problem created by predictive, more generally non-stateless encoders in TFO operation.

IPC: G06F17/21
Filed: 2000-10-17
Abstract: A computer-implemented template provides a structure for a document. The template may provide zero or more region definitions and zero or more placeholders. Region definitions may be associated with data provided in data providers. There are two types of data providers, namely software data providers and non-software data providers. Software data providers provide data through the execution of software code, whereas non-software data providers do not execute software code. A rendering engine renders the template pursuant to a rendering strategy. If a region definition in a template is associated with a region in a single data provider, the rendering engine replaces the region definition in the template with the located region. If a single region definition is associated with two or more regions, the rendering engine and the rendering strategy decide which region to use based upon a predetermined strategy. The placeholders in the template are replaced during the rendering process by their associated globally defined values.
