Abstract: A method of reducing speech delay and improving speech quality in digital transmission systems by implementing a single coder-decoder (codec) for an entire speech path from a calling party (21) to a called party (29, 52). The method is applicable to calls between mobile subscribers (21, 29) and between a mobile subscriber (21) and an H.323 client terminal (52) in a data network.  After obtaining location information for the called party, an indication of a requested codec is sent from the calling party to the called party utilizing Integrated Services Data Network User Part (ISUP) or Primary Rate Interface (PRI) out-of-band signaling during call setup. If the called party supports the requested codec, a confirmation of the requested codec is sent from the called party to the calling party. A speech path is then established between the parties, and a single codec translation is performed for the entire speech path. If the called party does not support the calling party's codec, but the serving MSCs (23, 27) for both parties support the calling party's codec, the calling party's codec is utilized all the way to the called party's serving MSC. One additional codec translation is then performed in the called party's serving MSC to convert to the codec supported by the called party.

Patent CA-2355311-A1 (CA)
Inventor: FRANK RYAN CLINTON
IPC: A47L13/17
Filed: 1999-12-29
Abstract: A basesheet for a wet wipe which includes multiple fibrous layers. At least one of the fibrous layers of the basesheet includes either 1) polyethylene fibers formed by a blend of polyethylene and an additive or 2) polypropylene fibers formed by a blend of polypropylene and an additive. For example, a fully hydrogenated hydrocarbon resin may be used as an additive with polyethylene to form polyethylene fibers which have a lower melting temperature of about 87 degrees Celsius. Polyethylene layers produced with such fibers may have an enhanced strength, produce less lint and be more securely attached to an adjacent fibrous layer. Polybutylene may be used as an additive with polypropylene to form polypropylene fibers to produce a more flexible layer with an increased attachment to an adjacent fibrous layer. The polyethylene and polypropylene layers may also include natural fibers such as cellulosic fibers. These polyethylene and polypropylene layers may both be present in a basesheet or may be combined with other fibrous layers. One or both of the major exterior surfaces of the generally planar basesheet may be formed by a polyethylene layer to provide the basesheet with a relatively soft exterior wiping surface. The polypropylene layer may be advantageously combined with a softer layer to provide strength and resiliency to the basesheet. A three ply basesheet may include an inner polypropylene layer and two outer polyethylene layers to thereby take advantage of the different properties of these layers. The use of an additive with either the polyethylene or polypropylene fibers allows the properties of the basesheet to be further controlled to suit the basesheet for its intended purpose.

Patent CA-2381280-A1 (CA)
Inventor: GASCOYNE JOHN M
IPC: H01M8/10
Filed: 2000-08-23
Abstract: In a solid polymer fuel cell series, various circumstances can result in the  fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel (for example, fuel starvation). In order to pass current during fuel starvation, reactions other than fuel oxidation may take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter m ay result in significant degradation of the anode. Such fuel cells can be made more tolerant to cell reversal by promoting water electrolysis over anode component oxidation at the anode. This can be accomplished by incorporating a catalyst composition at the anode to promote the water electrolysis reaction , in addition to the typical anode electrocatalyst for promoting fuel oxidatio n.

Abstract: An apparatus and method for treating an undesired presence on an individual includes a CPU coupled to a laser control unit and a robotic arm control uni t. A scanning area or volume is defined on the individual that includes the undesired presence. The CPU controls the robotic arm to move the laser and camera about the scanning area or volume while the camera scans individual portions of the scanning area or volume. The CPU receives this information from the camera and determines, based on the scanning, whether a particular portion includes part of the undesired presence. When the particular portion  includes part of the undesired presence, the CPU actuates the laser. This process continues for all portions of the scanning area or volume. In an alternative embodiment, the CPU controls the robotic arm control unit to sca n the entire area or volume and determines locations where there is an undesir ed presence. The CPU then again moves through the area or volume and actuates t he laser at locations which will treat these undesired presences.
