Title: Method and apparatus for spectrum analysis
Inventor: KIBRIA MASUD
IPC: H04M1/24
Filed: 1996-08-07
Granted: 2002-04-09
Abstract: A method and apparatus for remote spectrum analysis is disclosed. A channel measurement device is configured to receive and measure the radio spectrum in a geographic location during a measurement phase of operation. A microprocessor processes the signals and stores processed data on a storage device. The channel measurement device contains a communications interface to a land line telephone network and/or a cellular telephone network. During a data transfer phase of operation, the channel measurement device sends the processed data to a remote processor via the land line or cellular telephone network. In addition, the remote processor may act as a remote user interface to control the operation of the channel measurement device. In particular, the remote processor may be used to store values for user programmable configuration parameters in a memory of the channel measurement device via the land line or cellular telephone network. In one embodiment, the cellular telephone network interface may include the components necessary for communicating directly with the cellular telephone network. In another embodiment, the cellular telephone network interface is capable of connecting to a cellular telephone for such communication with the cellular telephone network.

Abstract: A method for calibrating a probe apparatus includes positioning a probe such that a known point on the probe is located at an arbitrary location within a selected volume with respect to a support base of the probe apparatus. The orientation of the probe is varied to move a plurality of joints of a mechanical linkage assembly coupled to the probe while maintaining the known point on the probe at the arbitrary location. Sets of data are sampled at a plurality of orientations of the probe as the orientation of the probe is varied about the arbitrary location.  The sets of data are provided by sensors and describe different configurations of angles of the joints. Spatial coordinates for the known point on the probe are determined at each of the plurality of orientations of the probe. An error value between the spatial coordinates determined for each of the plurality of orientations is determined. The accuracy of positioned and orientation data provided by the probe apparatus is increased by determining calibration parameters based on the error values. The calibration parameters are used when determining the position and orientation of the probe in normal usage.

Title: Apparatus and method for cooling a product
Inventor: VERSTEIJNEN CAROLUS MARINUS BE
IPC: F25D31/00
Filed: 1995-11-07
Granted: 2005-08-09
Abstract: An apparatus for cooling a product comprises a first evaporator (14) and a second evaporator (15) separate from the first evaporator (14), a first heat exchanger (16) incorporating the first evaporator (14) and a second heat exchanger (17) incorporating the second evaporator (15). In operation, the product or an intermediate heat transfer medium is cooled in at least two first stages. During the first stage, heat is withdrawn from the product or the medium by the first evaporator (14) cooling the product or the medium to an intermediate temperature. During the second stage, heat is withdrawn from the product or the medium by the second evaporator (15) further cooling the product or the medium to the desired temperature. Since the product or the medium is partially cooled by an evaporator operating at a higher evaporating temperature than required for achieving the desired temperature, an improved energy efficiency is achieved.

Patent CA-2237042-C (CA)
Inventor: JACONELLI GEORGES
IPC: B65H18/28
Filed: 1998-05-06
Granted: 2002-11-05
Abstract: The present invention relates mainly to a machine for winding film, to a method of manufacturing spools of pre-stretched film, and to spools of pre-stretched film obtained thereby.  The method of winding spools of pre-stretched stretchable film of the invention includes importing oscillation to the film, advantageously with a component perpendicular to the axis of the film.  For example, during pre-stretching and winding of the film on a take-up spool, a feed spool, i.e. a spool from which the stretchable film for stretching is taken, is caused to oscillate, and/or the take-up core is caused to oscillate.  This ensures that successive layers of film are offset, in particular at the margins of the film. Spools of film obtained in this way do not have portions of extra thickness and lower tension at the margins as is the case for prior art spools of pre-stretched film.  The present invention is mainly applicable to wrapping, with the film being paid out manually.

Title: Methode de reduction des emissions de nox dans un four
Inventor: HUNDEBOL SOREN
IPC: C04B7/43
Filed: 1997-01-22
Granted: 2003-09-16
Abstract: L'invention porte sur une méthode de réduction des émissions de NOx produites par un four destiné au traitement de matériaux bruts et dans lequel le combustible peut être allumé dans au moins trois zones différentes. Dans une de ces zones, une quantité c de combustible est brûlée; dans une seconde zone, une quantité b de combustible est brûlée. C'est dans cette seconde zone que les gaz d'échappement contenant du NO et provenant d'au moins deux autres zones sont acheminés. Dans le reste des zones une quantité a de combustible est brûlée et au moins une partie des matériaux bruts est placée dans ces zones avec un gaz contenant de l'oxygène. La quantité totale de combustible, a + b, dans la seconde et les dernières zones, est déterminée par le niveau de traitement requis par les matériaux bruts. Lorsque le four est utilisé pour produire du ciment non broyé, le traitement thermique comprend le préchauffage, la calcination, le frittage et le refroidissement des matériaux minéraux bruts. L'invention vise à fournir une méthode par laquelle on obtient une réduction des émissions de NOx, ce qui permet en même temps d'utiliser des combustibles de faible réactivité comme le coke de pétrole, l'anthracite et autres charbons produisant peu de gaz, dans des zones où la température est relativement basse. Conformément à l'invention, l'objectif est atteint en ce sens que l'alimentation des combustibles b+a est réglée vers le haut et vers le bas jusqu'à l'obtention d'une teneur minimale en NO dans les gaz d'échappement à partir des zones où il y a des gaz d'échappement contenant des NO par rapport à toutes les autres zones d'alimentation en combustible.

Abstract: A bandsaw (21) and bandsaw controller (39) adapted for control of at least one of the feed rate, cutting force and cutting speed of a bandsaw blade (24) as the blade cuts a workpiece (26). The controller includes an input device (61) adapted to provide signals to the cutting rate control assembly including a cutting rate signal, a break-in mode signal and a break-through mode signal.      The cutting rate control assembly is responsive to the break-in mode signal to begin cutting of workpiece (26) at a break-in cutting rate below the desired cutting rate and to increase the break-in cutting rate automatically, as a function of time until the desired cutting rate is achieved. The cutting rate control assembly is further responsive to the break-through mode signal to reduce the saw cutting rate just before the saw blade (24) exits from the workpiece (26). A method of operation of the bandsaw (21) to effect saw blade break-in and prevent detrimental saw blade break-through also is provided.

Abstract: A method of canceling echo signals in a telephone network operating in a double talk mode has been developed.          A system for implementing the method is also presented. In the invention the conventional normalized least mean square (NLMS) algorithm for echo cancellers is modified such that echo path changes continue to be tracked even after a double talk condition has been detected. The modified algorithm, known herein as a double-talk normalized least mean square (DNLMS) algorithm adaptively adjusts the convergence rate based on the power difference between the echo signal or the residual signal and the far end signal.
