Patent CA-2210943-C (CA)
Title: Control arrangement and method for high-speed source-transfer switching system
Inventor: O'LEARY RAYMOND P
IPC: H02J3/38
Filed: 1997-07-21
Granted: 2004-11-23
Abstract: A control arrangement and method is provided for high-speed source-transfer switching systems (HSSTSS). The HSSTSS supplies an electrical load with alternating current from either a first source or a second source via respective first and second solid-state switches. The HSSTSS also includes a controller that samples the voltage waveforms of each of the first and second sources to detect when transfer between the sources is desirable, e.g. outages or voltage that is either too low or too high. The controller provides appropriate control signals to control operation of the solid-state switches and transfer supply of the load therebetween.   The control arrangement avoids undesirable current flow between sources via a comparison of the voltages of the sources and current in the outgoing source, i.e. a polarity comparison to ensure that the current that will flow in the incoming source after transfer will be in opposition to the current flowing in the outgoing source before transfer. Thus, the transfer is delayed until the polarity comparison is satisfied. Either separately or in combination with the polarity comparison, the control arrangement minimizes undesirable transfer delays by establishing a forced commutation condition before issuing control signals to perform the transfer between sources, i.e. the transfer is delayed until after a forced commutation condition of the current in the outgoing source is established. The forced commutation condition is preferably established by the incoming source voltage differential and the outgoing current being of the same polarity such that the voltage differential across the solid-state switch that is being turned on will establish an initial change in current flow in opposition to the current flow in the solid-state switch to be turned off.

Title: Tire balancing using glass beads
Inventor: LEBLANC ROGER
IPC: B60C19/00
Filed: 1997-09-29
Granted: 2002-09-17
Abstract: A free-flowing material made up of glass beads. The glass bead material are introduced into a imbalanced tire. The motion of the imbalanced tire encourages the glass bead material to migrate to areas of the inside tire lining so as to correct the imbalance. Once the tire is balanced, the glass bead material migration come to a general stop and generally remain on the resting area of the inside tire liner until a sudden shock is applied on the tire.

Abstract: Products and methods for controlling the porosity and permeation of a web are provided using a curable thixotropic shear thinnable polymer composition that preferably encapsulates a plurality of fibers of the web and/or forms an internal layer within the web. Webs suitable for several different uses are featured, for example medical garments resistant to permeation by a virus or bacteria. The effective pore size of the web is controlled by regulating various factors such as the thickness of the polymer composition encapsulating the fibers and the thickness and placement of the internal polymer layer. Other factors include the polymer density, structure, and crosslinking orientation, as well as the diffusion, permeation and sorption of the polymer.

Title: Employing customer premises equipment in communications network maintenance
Inventor: BOWKER DUANE OLIVER
IPC: H04M3/00
Filed: 1998-03-19
Granted: 2001-05-22
Abstract: The present invention customizes a network connection to customer premises equipment using a calibration signal. A network signal processor emits a tag signal indicating that a signal processing plafform is in use. Customer premises equipment (CPE) issues a calibration signal to the network signal processor based on detection of the tag signal. The customer premises equipment outputs the calibration signal to the network signal processor which measures the signal loss, adjusts the gain mapping and issues a calibration signal to the customer premises equipment. The customer premises equipment then estimates spectral shaping based on the calibration signal from the network signal processor and equalizes the receive path so that the signal processing platform is detected and implemented. Embodiments of the present invention are illustrative of a more general concept of the use of CPE as an agent in telephone network maintenance.
