Title: Methods and apparatus for echo suppression
Inventor: RABIPOUR RAFI
IPC: G10L21/0208
Filed: 1997-10-15
Abstract: In methods and apparatus for suppressing echo of a far end signal (114) encoded using LPC-based compression in a near end signal (112) encoded using LPC-based compression, parameters of each frame of the near end encoded signal (112) are processed without synthesizing a speech signal from the near end encoded signal (112) to determine whether sufficient echo to merit echo suppression is present in the frame. Upon determining that insufficient echo to merit echo suppression is present in the frame, the parameters of the frame are passed unmodified. Upon determining that sufficient echo to merit echo suppression is present in said frame, the parameters of the frame are modified without synthesizing a speech signal to suppress echo in the frame. The methods and apparatus are particularly suitable in codec bypass applications.

IPC: A23G9/12
Filed: 1997-10-21
Abstract: An apparatus (10) for at least partially freezing a food product which is at least partly liquid in a batch mode is disclosed including a double screw extruder (12) including first and second, substantially intermeshing, self-wiping screws (14, 16) rotatably received in a figure 8-shaped barrel (30) with minimal clearance. In the preferred form, the freezing block (20) includes multiple refrigerant channels (36) spaced closely and in the most preferred form spaced approximately 0.32 centimeters from the barrel (30) and from each other. Thus, the refrigeration system can change the barrel surface temperature rapidly and specifically in approximately one second when the food product is introduced into the barrel (30). A ratio between the radius of the flight (40) at the crest (42) to the radius at the root (38) of the screws (14, 16) is in the order of 1.04 to reduce the total amount of product in the barrel (30) at any given time and decreasing the product residence time in the extruder (12). In the most preferred form, the food product is aerated and is supplied in discrete volumes from at least one and preferably from multiple sources (48), with the supply of discrete volumes for individual servings being delayed to substantially prevent intermixing in the extruder (12).

Patent CA-2280963-A1 (CA)
Inventor: DRECHSLER JAN
IPC: E21B33/127
Filed: 1998-02-03
Abstract: The invention relates to a downhole seal (10) of the balloon type, formed to sealingly bear, in use, by its outer circumferential surface on, for example, the inner shell surface of a production riser (12). To prevent that the pressure inside the inflated seal, because of temperature variations, either gets so high that the seal (10) bursts, or so low that the seal (10) loosens and loses or reduces its effect, the seal (10) has a thereto connected pressure compensator (16), which is arranged to adjust the internal pressure of the inflated seal (10) in relation to the pressure of the surroundings on the underside/downstream of the seal, which will thus make a true reference pressure for the internal pressure of the seal (10). By increasing pressure inside the inflated seal (10) the ambient pressure permits a leakage of the liquid/gaseous inflating medium of the seal to maintain a largely constant internal pressure in the seal (10), whereas by a falling pressure inside the seal (10), the ambient pressure causes it to rise by supplying additional inflating medium from a reservoir (26), to maintain the pressure desired for the seal (10).

IPC: H04L69/40
Filed: 1999-10-28
Abstract: A technique is provided which advantageously facilitates the dynamic recovery from faults in one or more communication channels. In accordance with the technique, the dynamic adjustment of DSL bandwidth allocation and/or symmetry across communications channels is combined with a dynamic bonding mechanism that, in cases of single or multiple loop failures, creates the appearance of a single higher-bandwidth channel by combining and/or distributing the communications traffic across the still available physical communications channels. In this way, the channel bonding technique advantageously facilitates the dynamic recovery from faults in one or more communication channels while preserving a symmetric bandwidth channel allocation.

Title: System and method for determining a handoff target base station in a mobile communication system
Inventor: YU TAE HO
IPC: H04B7/26
Filed: 1999-05-08
Abstract: A mobile communication system performs handoff taking into consideration a travelling direction of a mobile station. A mobile station measures strengths of pilot signals from base stations adjacent thereto and transmits information about the measured strengths to a BSC. The BSC then selects one of the base stations as a handoff target base station depending on the measured strength information and location information of the mobile station and the base stations. The weights are applied to the adjacent base stations according to directions of the adjacent base stations based on a travelling direction of the mobile station, which is predicted according to movement of the mobile station.
