Patent CA-2278708-A1 (CA)
Title: Arcing fault detection system
Inventor: HAUN ANDY A
IPC: G01R31/12
Filed: 1998-01-23
Abstract: A system for testing an arcing fault detection system including a sensor (21a) coupled to the line conductor for monitoring the electrical signal and generating a sensor signal representing the electrical signal. The sensor simultaneously monitors the test signal and the electrical signal when the test signal is present on the test line. The arcing fault detection system generates an arc-indicative signal in response to the sensor signal associated with either the test line or line conductor having characteristics indicative of an arcing fault. A diagnostic test integrator evaluates the status conditions of the test signal and the arc-indicative signal and generates a trip signal to trigger the interruption of the electrical signal in response to certain status conditions of the test signal and the arc-indicative signal.

Title: Apparatus for and method of taking a predeterminable volume of a sample of medium
Inventor: LEBSKI HUBERT
IPC: G01N1/10
Filed: 1999-07-29
Abstract: The apparatus makes it possible to change a desired sample volume - even during operation - in a simple manner without mechanical intervention, with any accumulation solids of a sample contained in a sample collecting vessel being avoided, so that a sample representative of the medium is obtained.      The apparatus comprises a control unit which controls a pneumatic control gear and switches a pump by means of which the medium is drawn into a sample collecting vessel via a hose or tube used as a suction line. A detection unit incorporated in the suction line signals the presence of the medium to the control unit, which then controls the time period for taking the desired volume of the sample. The sample volume obtained is drained off into a sample container via a drain device.

Patent CA-2283778-A1 (CA)
Title: Flicker photometer
Inventor: HUANG WENLUE
IPC: A61B3/06
Filed: 1998-03-04
Abstract: A flicker photometer comprises generating means for generating two beams of light of different colours. Both beams are directed to a viewing means and a subject can vary the intensity of light from one beam relative to other. The colour of the light seen by the subject is caused to alternate by a shutter which is rotated about an axis by a motor, the shutter having a portion which extends non-perpendicularly relative to the axis to facilitate a compact construction of photometer. The performance of the photometer is improved by screens which scatter light before it reaches the subject. A first of the screens reflects light from one beam, whilst a second screen transmits light from the other. If light of wavelengths to which the eye is less sensitive is passed through the second screen, whilst light of a wavelength to which the eye is more sensitive passes through the first screen, the screens help to make it practicable for the generating means to use a single lamp to produce the light for both beams.

Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1999-03-17
Abstract: The effects of interfacial transition between organic and inorganic layers of a lithographic printing member are ameliorated by incorporating an inorganic component within the matrix of the organic layer.  In a first aspect, a lithographic printing plate having adjacent organic and inorganic layers is fabricated by depositing a curable polymer, softening the polymer, and integrating an inorganic material therewith. The polymer is then cured to immobilize the integrated deposition material, and the desired inorganic layer is applied over the deposited inorganic material (and any exposed portions of the polymer). In a second aspect, a graded structure is built up on a substrate in successive deposition steps. Both polymer precursors and an inorganic filler material are deposited in stages, with each stage containing a desired ratio of polymer to filler.

IPC: H04L47/265
Filed: 2000-06-07
Abstract: Disclosed is an apparatus and method of monitoring a queue state of a switch in a subscriber board of an asynchronous transfer mode switching system. A difference value between a present time value and a previous input time value stored in a memory per connection is inputted to a forward resource management (FRM) cell when a resource management (RM) cell is inputted from a source, and a switch load measurement value written in the FRM cell is obtained by calculating a difference value between the present time value and a previous output time value stored in the memory per connection when the FRM cell transmitted from the source passes through the switch. The obtained switch load measurement value is inputted to a backward resource management (BRM) cell transmitted from a destination to be transmitted to the switch. Then, a queue state of the switch is judged by identifying the switch load measurement value which is applied to the BRM cell transmitted from the destination and passed through the switch, an explicit cell rate (ER) value is calculated according to the queue state of the switch, and the ER value is applied to the BRM cell to be transmitted to the destination.
