Patent CA-2238336-C (CA)
Inventor: CUHACI MICHEL
IPC: H01Q19/19
Filed: 1998-05-22
Granted: 2005-08-16
Abstract: Due to the frequency dependence of phasing mechanisms applied in planar printed reflectors, when using planar printed reflector antennas beam squint occurs as the frequency is scanned within the operating band. In order to reduce or eliminate beam squint, a n incident signal incident upon a reflector is altered in such a way that the outgoing signal retains a same direction. In an embodiment, this is achieved by providing feed elements in different locations, each feed element for feeding a signal of a different frequency. In another embodiment, two reflector arrays are used wherein beam squint caused by the first reflector array is compensated for by the second reflector array.

Abstract: Static fade in a digital video image is detected. A difference in luminance intensity, is determined for correspondingly positioned pixels in successive images. A variance in the difference is determined, and then normalized according to a mean squared value of the difference to provide a fade index J n. The fade index is compared to a fade threshold, e.g., 0.9, to determine if a fade is indicated. Optionally, a check may be made to verify that a static fade is indicated by comparing the mean squared value of the difference to a motion threshold. The technique is suitable for both frame mode and field mode video sequences. When the digital images include field mode video, where each image has first and second fields, a fade index is determined separately for each field, and an overall fade index is obtained by averaging the fade indexes from each field. A scheme for detecting static fade on a macroblock by macroblock basis is also presented.

Title: Method for making lithiated manganese oxide
Inventor: PADHI AKSHAYA KUMAR
IPC: C01G45/00
Filed: 1999-05-12
Granted: 2005-08-23
Abstract: The invention is a process which provides a high purity lithiated manganese oxide (Li1+xMn2-yO4) from chemically made MnO2. The lithiated manganese oxide has an especially effective utility for use as a cathodic material in rechargeable batteries. The process of the invention includes blending a lithium compound with a chemically made manganese dioxide to form a manganese dioxide/lithium compound blend.      The lithium compound in the blend is at least about one mole of lithium for every mole of manganese dioxide. The manganese dioxide and lithium compound in the blend undergo an ion exchange reaction to provide an ion replaced product where lithium ions have replaced sodium and potassium ions in the MnO2 to form an ion replaced product. Thereafter, the ion replaced product is heated or calcined to provide the lithiated manganese oxide.

Abstract: A method for making hardwood or decorative plywood. The plywood includes a number plies including a back veneer, a face veneer, and a number of core and center plies. The method forms subunits of plies and stacks the discrete formed subunits to form a unit. The unit is processed to forms discrete hardwood panels. Subunits having different sets of plies are formed. The subunits are formed by sequencing the order of placement of the plies so that the face and back veneers do not touch the conveyor. This process enables line assembly of hardwood plywood. Without this sequencing, at least the back veneers would touch the conveyor subjecting the panel to aesthetic damage due to the nature of the outer veneers. This process also significantly reduced the labor necessary for forming the panels because numerous subunits can be formed simultaneously.
