Title: Dynamic routing of wireless communications
Inventor: ARAVAMUDAN MURALI
IPC: H04M3/00
Filed: 2000-11-30
Abstract: A method and apparatus for dynamic routing of wireless communications. More particularly, wireless communications are dynamically routed by marking, by a softswitch, every endpoint participating in a call and as the entry for a marked endpoint is updated a message is generated and sent to the softswitch. Upon receiving such a message, the softswitch re-computes the necessary new resources for maintaining the call and (i) instructs such new resources to negotiate media transfer, (ii) after receiving an acknowledgement from the new resources, transmits appropriate call initiation messages to such resources; and (iii) transmits call release messages to the prior, i.e., old, resources supporting the call. Advantageously, selection of the requisite resources to participate in a particular is driven by the knowledge of the communications network topology. As such, resources are selected which are topologically closer to the endpoint thereby increasing the efficiency of the network resources on a network-wide basis.
Patent CA-2327640-A1 (CA)
Inventor: BOWES KENNETH L
IPC: A61N1/18
Filed: 2000-12-06
Abstract: A device and method for electrical stimulation of a portion of the gastro- intestinal tract, defining a longitudinal axis. A proximal and at least one distal electrode set are arranged circumferentially about the portion of the gastro-intestinal tract in a plane substantially perpendicular to the longitudinal axis and in axially spaced relationship relative to each other. At least one power source provides a variable electrical stimulus to the electrode sets sufficient to stimulate the smooth muscle to produce a local circumferential contraction at each electrode set, wherein the electrical stimulus is variable between each of the proximal and distal electrode sets. A timing mechanism phase locks the electrical stimulus such that it is applied to the electrode sets successively, preferably in an overlapping manner, and repetitively. The axially spaced relationship between the electrode sets and the timing of the electrical stimulus are selected such that the local circumferential contractions are artificially propagated distally through the portion of the gastro-intestinal tract.

Abstract: The invention relates to a method and a device for flushing water toilets th at can be flushed with one or more selectable, adjustable amount(-s) of water, and that allows use/fitting during production of new toilets as well as easy  retrofitting in existing water toilets. The device for performing the method  is a complete cartridge replacing the existing float/valve flushing device. The discharged amount of water is determined by a pre-adjustable period of time between that point in time when an operating device for flushing (9S, 9 F) is actuated, and the point in time when the flusing reservoir discharge valv e (2), opened by said operating device, is automatically closed again, rather than sensing the water level inside the flushing reservoir and allowing said  level to control the closing of the discharge valve. The method and the devi ce are a. o. characterised by the adjustable period of time being determined by  a hydraulic timer device using water from the flushing reservoir for its operation.

Title: Ofdm timing and frequency recovery system
Inventor: MCGIBNEY GRANT H
IPC: H04L27/26
Filed: 1996-08-12
Abstract: A synchronizing apparatus for a differential OFDM receiver that simultaneously adjust the radio frequency and sample clock frequency using a voltage controlled crystal oscillator to generate a common reference frequency. Timing errors are found by constellation rotation. Subcarrier signals are weighted by using complex multiplication to find the phase differentials and then the timing errors.      The reference oscillator is adjusted using the timing errors. Slow frequency drift may be compensated using an integral of the timing error. Frequency offset is found using the time required for the timing offset to drift from one value to another.

Title: A method for closing and/or joining a connecting joint or joining seam between two pieces of galvanized sheet metal
Inventor: SCHWANKHART GERHARD
IPC: C23C24/10
Filed: 2001-09-05
Abstract: A method for closing and/or joining a connecting joint or joining seam between two pieces of galvanized sheet metal, in which zinc or a zinc alloy whose melting point is similar to that of zinc is heated to melting temperature and is continuously introduced into the connecting joint, with the heating being performed by a plasma jet without reaching the melting temperature of the steel sheet. The use of a plasma jet allows processing zinc or a zinc alloy without producing any disturbing zinc spatter. The zinc can be supplied as a wire, powder or granulate, whereby it is introduced under an inert-gas bell. This method can also be employed for post--galvanizing weld seams, with a second plasma jet welding set following a first one, it being mechanically coupled with the same and performing the galvanizing of the weld seam by the supply of zinc in wire form without melting the steel sheet anew. Tin foils are used in a special embodiment which are applied in the joining zone of a flanged edge.

Title: Model-based fault detection system for electric motors
Inventor: DUYAR AHMET
IPC: G01M99/00
Filed: 1997-06-20
Abstract: The present invention relates to a model-based fault detection system and method for monitoring and predicting maintenance requirements of electric motors. Since the method and system of the present invention is software based and utilizes data obtained from non-intrusive measurements, implementation costs are significantly less than prior art maintenance methods. The system comprises computer means coupled to sensors which provide continuous real-time information of the input voltage and current and motor speed. The system and method utilize a multivariable experimental modeling algorithm to obtain a mathematical description of the motor. The algorithm compares the modeled result with a measured result and quantifies the comparison in terms of a residual which is generated by subtracting the respective signals. A diagnostic observer analyzes the residual and determines if the motor is fault free or operating in a manner other than fault free. Upon detection of the impending fault, the diagnostic observer evaluates the measured variables of the motor, determines the deviation from the reference value and develops a diagnosis of the likely failed or failing component. Another embodiment of the present invention is particularly useful in the manufacture of fractional horsepower electric motors and especially in the performance of quality control testing.
