Patent CA-2580571-A1 (CA)
Title: Blind signal separation using array deflection
Inventor: GOLDBERG STEVEN J
IPC: H01Q3/00
Filed: 2005-09-23
Abstract: A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for generating N initial antenna patterns for receiving N different summations of the M  source signals, with N being less than M. The antenna array includes an elevation controller for selectively changing an elevation of at least one of the N initial antenna patterns for generating at least one additional antenna pattern so that at least one additional different summation of the M source signals is received thereby. A blind signal separation processor forms a mixing matrix comprising the N different summations of the M source signals, and the at least one additional different summation of the M source signals.  The mixing matrix has a rank equal to N plus the number of additional different summations of the M source signals received using the additional antenna patterns. The blind signal separation processor separates desired source signals from the mixing matrix.

Abstract: Radio-frequency identification (RFID) apparatus and methodology enable a plurality of or all of the RFID tags in a stack of items such as cartons and boxes~including items that do not have a line of sight to a reader~to be read.  An RFID system includes RFID tags and a transmission line. The RFID tags are mountable to items to be read and include an RFID circuit that generates tag energy when activated by activation energy from a reader. The transmission line carries activation energy from the reader and tag energy from the tags.  The transmission line is positionable in operative or coupling proximately to a plurality of the tags when the plurality of the tags are mounted to items and when the items are stacked. Accordingly, when carrying activation energy from the reader, the transmission line couples with and thereby enables activation of the plurality of the tags. Further, when the plurality of the tags are activated and generating tag energy, the transmission line couples with and carries the tag energy from the plurality of the tags. The transmission line can be configured as an elongated adhesive tape-like structure that can be adhered across a plurality of RFID tags mounted to a plurality of items. The transmission line can also be disposed on an inter-item reading device that can be positioned between adjacent rows of stacked items.

Title: Solid blunt for a needle assembly
Inventor: SCHMIDT PHILIP D
IPC: A61M5/32
Filed: 1999-12-21
Abstract: A solid blunt and a needle assembly having a solid blunt. The solid blunt helps to prevent accidental needle sticks. In one exemplary embodiment, a solid blunt has an outer dimension (e.g. outer diameter) which is nearly equal to an inner dimension (e.g. inner diameter) of a cannula of a needle which is configured to contain the solid blunt. In one example, the solid blunt substantially blocks fluid flow in a first circumferential portion of an inner diameter of the cannula and allows fluid flow in a second circumferential portion of the inner diameter.  The solid blunt is typically capable of longitudinal movement through the cannula and is prevented from moving substantially in a direction perpendicular to the longitudinal movement. A needle assembly, in another exemplary embodiment, includes a solid blunt, a cannula and a clip which couples slidably the solid blunt to a frame which is coupled to the cannula. The present invention may be used with medical devices including needles, introducers and catheters and other devices as well.

Title: Specific bacterial inclusions in bone marrow cells indicate systematic lupus erythematosus, and treatment for lupus
Inventor: KALLICK CHARLES A
IPC: C12Q1/04
Filed: 2006-08-03
Abstract: A method for diagnosing for the presence of systemic lupus erythematosus (SLE) in a patient is disclosed. In accordance with this method, megakaryocytes present in bone marrow of a person suspected of having SLE are assayed for the presence of internal bacterial structures that specifically stain with an intercalating dye. The presence of those specifically stainable structures within the patient's megakaryocytes indicates that the patient has SLE.  Treatment of an SLE patient with an antibiotic is contemplated. Treatment of a patient that has SLE comprises administering to that patient (i) an antibacterial amount of a rifamycin along with an antibacterial amount of a macrolide, (ii) an antibacterial amount of a tetracycline, or (iii) an antibacterial amount of a quinolone, or a mixture of two or more of (i) , (ii) and (iii). The treatment is continued until the patient's megakaryocytes no longer contain specifically stainable structures, and until no further evidence of infection is present.

Inventor: KIMURA KAZUYOSHI
IPC: E04B1/94
Filed: 2006-08-08
Abstract: A wooden building member having a load receiving elongated structure section with a rectangular cross-section, a cover section for covering the entire length of at least three sides of the cross-section of the structure section, and an insulation section interposed, in a layer form, between the structure section and the cover section and preventing a load applied to the structure section from being transmitted to the cover section. Because the structure section takes a load, design of structure bearing force is facilitated. Also, even if the cover section is completely burnt in a fire, the structure section covered by the cover section is not easily burnt, so that fire resistant performance of the wooden building material is increased. Further, since the surface of the wooden building material is covered by the cover section, the insulation section is not exposed to the outside, which maintains a good appearance of the wooden building material.
