Abstract: A faulted circuit indicator comprises a processor, which dynamically determines a conductor de-energization level based on a monitored average current. This dynamically-determined de-energization level and/or monitored average current may be used to provide dynamic inrush restraint and/or dynamic backfeed restraint (reset restraint). If current within a power conductor falls below the determined de-energization level, the processor determines that the conductor has de-energized, and accordingly ignores high current spikes less than a predetermined duration that occur during re-energization.

Patent CA-2639424-A1 (CA)
Inventor: JOHNSON RYAN LORON
IPC: B43L5/02
Filed: 2008-09-09
Abstract: Improvements in the instruments for drawing lines using grooves providing the presentation of lines that may be drawn by placing a sheet of paper over the presentation and engaging the sheet of paper with the point of a writing tool with sufficient force to press the engaged part of the paper into a selected groove and then moving the writing tool point within the line, depositing pencil lead or ink from the end of the writing tool on the paper that is pressed into the selected groove to form a line on the paper.  The improvements include the provision of registration marks on a clipboard which has the presentation of grooves for lines to be drawn on the upper side of the clipboard, the registration marks acting as guidelines for the precise placement of the sheet of paper on which lines are to be drawn and its retention in that placement by a clip attached to the end of the clipboard and engaging the end of the sheet of paper for such retention. This precise placement of the sheet of paper allows a sheet of paper that has had one or more lines drawn on it in the manner noted above to be removed and later replaced on the clipboard in precisely the same location as it had when the line or lines were earlier drawn on it, with the result that any additional lines to be drawn will be in perfect relation to the lines earlier drawn, and the later drawings and the earlier drawings appear to have been made just as if the sheet of paper had not been removed between such drawings. Various shapes of such marks may be employed. Another major improvement is the provision of a turntable as a part of the upper surface of the clipboard, with the presentation of the array of grooves being in the upper surface of the turntable, and the turntable may be rotated under the sheet of paper to allow the drawing of lines at different angles to each other. The amount of rotation of the turntable is limited to a desired amount of arcuate movement, within ranges of 90°, 180°, 270°, or 360°. Another improvement is the ability to use different turntables having different types of arrays of grooves which are easily substituted as desired, not requiring completely different clipboard assemblies.

Title: Revolving tissue sample holder for biopsy device
Inventor: SPEEG TREVOR W V
IPC: A61B10/02
Filed: 2008-11-19
Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.

Abstract: The invention, which relates to a method for monitoring the load on rotor blades of wind energy installations by means of acceleration measurements on at least one rotor blade of a wind energy installation and the determination of the load on the rotor blade from the picked-up acceleration signals, is based on the object of specifying a method with which dynamic, even uncritical load states can be detected, in differentiated fashion, and combined in a suitable form for evaluation in order to influence, if possible prior to the onset of damage to the rotor blade, the mode of operation of the wind energy installation, in particular the design of the pitch control or angle setting of stall-regulated rotor blades, on the basis both of all of the rotor blades together and of a single rotor blade. This problem is solved by the frequency of the occurrence of the load values over a certain period of time being determined from the amplitudes of the time signal or the amplitudes of selected natural oscillations of the frequency spectra obtained by Fourier transformation.

Abstract: The invention relates to devices having periodic refractive index modulation structures and fabrication methods for the devices using a laser means. By focusing a pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. By selecting appropriate laser parameters and relative scan speed, the laser modified path defines an optical waveguide. Separation distance of the individual modified volumes define a periodic modification pattern along the waveguide path, so that the waveguide structures also exhibit grating responses, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. This method of direct laser fabrication enables one-step fabrication and integration of periodic or aperiodic refractive-index modulation devices together with optical waveguiding properties to enable low-cost, multifunctional I D, 2D or 3D optical circuit fabrication for simple and complex applications.

Title: Designation of delegate for modifying an electronic meeting definition defined using electronic calendaring software
Inventor: BREDIN ROB
IPC: G06Q10/00
Filed: 2009-02-06
Abstract: A command identifying an electronic meeting definition created by a meeting organizer, using electronic calendaring software, and a modification to be made thereto is received from a user who is distinct from the meeting organizer. Based on the identified meeting definition, the user is determined to be a delegate of the meeting organizer for modifying the identified meeting definition, but not necessarily other meeting definitions. Based on that determination, a command for causing the software to modify the meeting definition is generated. The generated command is made to appear to the software as having originated from a user having sufficient privileges to modify the meeting definition (e.g.  the meeting organizer). Delegates may be designated on a meeting-specific basis through a user interface. The designation may result in storage of a data record for future use in determining whether commands to modify that meeting definition shall be effected.
