Patent CA-2266149-A1 (CA)
Inventor: MCGIBNEY GRANT
IPC: G10L19/14
Filed: 1999-03-18
Abstract: This invention modulates voice signals so that the radio waves behave the same in the radio medium as sound waves would in the acoustic medium. This is accomplished by segmenting the voice signal and compressing the segments in time before transmitting them through the radio channel. If the compression factor is correct, the distortion sounds natural to the ear because the characteristics of the radio channel match those normally encountered in the acoustic channel. The radio signal will then inherit many of the good properties of acoustic voice signals including resistance to flat fading and tolerance of frequency selective fading.

Patent CA-2270597-A1 (CA)
Title: Path-based restoration for mesh networks
Inventor: CHAUDHURI SID
IPC: H04L12/56
Filed: 1999-05-03
Abstract: Restoration of service in a mesh network upon the failure of a working channel on a link connecting a pair of nodes is accomplished by first attempting to route traffic on an restoration channel in the same link when such a channel is available. If such "localized" restoration can not be accomplished, then the end- point (traffic originating and/or terminating) nodes that are connected by a path that includes the link having the failed working channel then implements a pre- computed path. Each pre-computed path identifies a collection of channels in a series of links that connect the end-point nodes (and any intermediate nodes) so as to bypass traffic around the link having the failed working channel. The pre- computed path information is typically pre-stored in the end-point nodes to enable the end-point nodes to effect rapid restoration in the event localized restoration is not achievable.

Title: Absorbent article and method and apparatus for manufacturing same
Inventor: BOULANGER ROGER
IPC: A61F13/15
Filed: 1997-12-30
Abstract: The invention relates to a sanitary absorbent article and to a component layer thereof than can be produced with less waste material. The invention also extends to a method and an apparatus for manufacturing the sanitary absorbent article and the component layer. The method is characterized by the step of cutting a continuous web of material to form a pair of sanitary absorbent articles, each article including a pair of laterally projecting flaps. The contour of each article is selected so the flaps can fit close to one another with the flaps of two adjacent articles contacting one another at their sides rather than the lateral extremities. This arrangement allows to bring the main bodies of the sanitary articles close to one another, thus reducing the inter-article waste.

Title: Zero-delay slew-rate controlled output buffer
Inventor: GARCIA FLORENT
IPC: H03K17/16
Filed: 1998-11-16
Abstract: An output buffer (100; 200) in accordance with the present invention exhibits a fixed output signal slew rate. The output signal behavior is independent of the capacitive load (CL) seen by the buffer. The circuit includes a capacitive feedback path from the output node to circuitry which drives the output transistors. In one embodiment, the feedback path comprises two capacitive elements (CFP, CFN), one which comes into play during a rising edge transition and the other which affects a falling edge transition. In a second embodiment, a single capacitive element (CF) is coupled to a switching circuit (P4, N4) for use during either a falling transition or a rising transition. The second embodiment provides precharging of the output transistor gates, and so improves response time.

Title: Gas turbine combustor cooling structure
Inventor: NISHIDA KOICHI
IPC: F23R3/00
Filed: 1999-11-04
Abstract: Cooling structure of gas turbine combustor in which cooling medium flows through grooves in wall is improved so that adjustment of flow velocity, pressure loss and heat transfer rate of cooling medium flow in the wall becomes possible and cooling effect thereof is enhanced. Wall of combustor tail tube is made in double structure in which outer plate (1) and inner plate (4) are jointed together being lapped one on another. The outer plate (1) has air inlet hole (3) and groove (2) formed therein. The groove (2) is closed by jointing of the inner plate (4) to the outer plate (1).      The inner plate (4) has air outlet hole (5) formed therein.      The groove (2) communicates with the air inlet hole (3) and the air outlet hole (5). Cross sectional shape of the groove (2) is changed two-dimensionally or three-dimensionally such that width enlarges toward the hole (5) from the hole (3) or depth is constant or changed in tapered form. Cooling air flows into the groove (2) from the air inlet hole (3) of tail tube surface to flow toward both sides along the groove (2) for cooling of the wall. The air is thereby heated to expand to increase flow velocity and pressure loss, but flow passage enlarges toward the hole (5) and flow velocity is suppressed and pressure loss is reduced.
