Patent CA-2595296-C (CA)
Title: Method for determining the orientation of an antenna array
Inventor: EULER HANS-JUERGEN
IPC: G01S19/55
Filed: 2006-01-18
Granted: 2012-09-18
Abstract: The aim of the invention is to limit the number of possible phase ambiguity resolutions when taking measurements by means of satellite-aided positioning systems. Said aim is achieved by a method which allows the search sector to be better restricted. To this avail, information about the geometry of an antenna array is used for establishing restrictions for said antenna array. Said restrictions allow the search sector and thus the number of acceptable resolutions to be successively reduced. A restriction comprises the utilization of the connecting line between two antennas that define a primary base line. An additional, secondary base line can be calculated by inventively parameterizing the degree of rotational freedom of said secondary base line about the primary base line such that the process is accelerated.

Granted: 2012-05-22
Abstract: A method is disclosed for detection of miniature security mark configurations within documents and images, wherein the miniature security marks are in the form of dispersed miniature security marks and may include data marks or a combination of data marks and anchor marks. The method includes sub-sampling a received image, which is a digital representation possible recipient(s) of the miniature security marks, to generate a reduced-resolution image of the received image. Maximum/minimum points detection is performed and the maximum/minimum points are grouped into one or more clusters according to location distances between the maximum/minimum points. Group configuration is checked to match the clusters with a pre-defined template configuration. Dot parameter verification is then performed to verify mark location and configuration between the received image and a pre- defined template dot specification.

Abstract: Apparatus embodying the invention include a damping plate attached to1 the submerged end of a spar-like element floating in a body of water. The spar like element tends to move up and down in a vertical direction in response to passing waves. The damping plate has a pair of oppositely facing surfaces extending transversely to the vertical direction of the movement of the spar-like element and vertical structures ("lips") mounted on the oppositely facing surfaces for increasing the effective mass of water pushed during movement of the damping plate through the water. Damping plates with lips, as per the invention, may be used in wave energy converters to control the relative motion between the spar- like element and a float to increase the energy produced. Damping plates with lips, as per the invention, may be used to effectively dampen the motion of an offshore platform to which the spar-like element is fixedly attached.

Title: Non-invasive neuro stimulation system
Inventor: THOMPSON THOMAS C
IPC: A61N1/00

Granted: 2015-05-19
Abstract: A device is used to apply an electric pulse or spike to a patient to treat the patient.  The device can have a series of preset treatments programmed therein. A user can select a treatment from menus displayed on a display. The impedance of the skin and underlying tissue to be treated can be measured prior to the treatment to locate active areas on the skin for treatment. The impedance measurement. can be made at a sufficiently low level to avoid treatment of the patient that could cause a change in the impedance. A phase detector can be used to isolate the capacitance value in the impedance. The charge delivered to the patient can be measured and the device can adjust the charge as the skin impedance varies during treatment to deliver uniform charges to the skin. A variety of probes can be used with the device, with the device automatically detecting the type of probe attached. Multiple electrodes can be used on the probe, which allows the active areas in contact with the probe to be identified prior to treatment to allow the treatment to concentrate on the active areas.
