Patent CA-2452158-A1 (CA)
Inventor: ROBERTS JEFFREY B
IPC: H02H3/30
Filed: 2002-07-01
Abstract: In a three terminal (200, 202, 204) power line current differential protection system, all three phase current values are obtained from all three terminals.  The current values for each phase are processed in three successive processing operations, using in turn the current values from each terminal as local current values and the combination of the other two terminal current values in each case as the remote current values. The resulting local and remote current values are then processed against preselected values, which establish a restrain region in the current ratio "alpha" plane. Current values for each set of local and combined remote currents which result in the ratio being within the restrain region (30) result in a blocking signal while current values, which result in a ratio outside of the region result in a tripping signal. If the outputs of the three processing operations agree, then that signal is the system output. If there is disagreement, the output produced when the terminal having the largest current value is the local current is the system output.

Title: System and method for manipulating illumination created by an array of light emitting devices
Inventor: KAN PETER
IPC: F21V5/00
Filed: 2003-12-08
Abstract: The present invention provides an illumination optical system that enables the direction and mixing of light from light emitting devices. The optical system comprises a plurality of light emitting devices that are spatially arranged in an array, wherein this array comprises one or more sections, such that the light emitting devices in a particular section emit light within a predetermined wavelength range. Through the use of a combination of macroscopic and microscopic optical systems, the illumination created by the array can be manipulated such that a desired illumination distribution is created. The macroscopic optical system provides a means for redirecting the illumination in one or more desired directions, wherein this redirection is provided by a collection of appropriately shaped and positioned reflective optics. Subsequent to its interaction with the macroscopic optical system, the illumination is manipulated by a microscopic optical system that enables the diffusion of the illumination in a predetermined manner, while retaining the desired angular distribution of the illumination created by the macroscopic optical system. Through the appropriate design and orientation of both the macroscopic and microscopic optical systems, a desired illumination effect can be created.

Title: System and method for sample detection based on low-frequency spectral components
Inventor: BUTTERS BENNETT M
IPC: G01N37/00
Filed: 2003-04-18
Abstract: Method and apparatus for detecting a selected material in a sample are disclosed. In the method, the sample (842) is placed adjacent a detector coil (846), for generating an electromagnetic time-domain signal composed of sample source radiation. The signal is first conditioned to convert the signal to an amplified conditioned signal from which frequency components above a selected frequency have been removed, then filtered to selectively pass low-frequency spectral components that are (i) in a frequency range between dc and 50KHz, and (ii) characteristic of the selected material. The filtered signal is cross-correlated with a data set of low-frequency spectral components that are (i) in a frequency range between dc and 50KHz, and (ii) characteristic of a selected material, to produce a frequency-domain spectrum in the frequency range within DC to 50KHz. This spectrum is then used to determine whether the frequency-domain spectrum contains one or more low-frequency signal components that are characteristic of the selected material, and diagnostic of the presence or absence of such material in the sample.

Abstract: A dual phase contaminated soil remediation apparatus having an air blower with a blower discharge conduit, which places the air blower in fluid communication with an air diffuser positioned in a lower portion of a groundwater holding tank. Air supplied by the air blower is discharged into the air diffuser and bubbles up though contaminated groundwater in the holding tank, thereby providing an air stripping treatment to the contaminated groundwater. A first air supply conduit supplies air from atmosphere to the air blower and a second air supply conduit supplies air from the well to the air blower. When the second air supply conduit is used, a suction force is applied to the well to extract hydrocarbon vapours. A float activated valve selectively switches between the first air supply conduit and the second air supply conduit, depending upon the groundwater level in the holding tank.
