Patent CA-2209702-A1 (CA)
Inventor: BROCKBERG JAMES A
IPC: H01K3/32
Filed: 1997-07-10
Abstract: A light bulb manipulating device (10) which comprises a unitary plastic structure (11), a vacuum forming means (12), and extension means is disclosed. The device (10) incorporates a receptacle (15) with a flexible, annular rim (20). The device (10) can manipulate a wide variety of sizes and types of remotelight bulbs ranging from conical or globe-type bulbs to essentially flat, flood or spot lights and is, therefore, versatile, economical, and easily operated. A pole (30) of varying length is threadably engaged to the device (10) so that an operator can manipulate remote or overhead bulbs from the ground without the use of a ladder,stool or other support surface.

Title: Dynamic patella brace with floating patella pad
Inventor: PALUMBO PASQUALE
IPC: A61F5/052
Filed: 1995-06-14
Abstract: A dynamic patella brace (10) useful for both diagnosis and treatment of patella subluxation, wherein the position of a patella bracing pad (15) is allowed to float to be automatically dynamically repositionable depending upon the amount of flexion and movement of the knee and the amount of tension and pressure applied is provided. The brace (10) includes an elastic sleeve (20) having an aperture (21) for registration and alignment of the knee therein. Additionally, the brace (10) includes a strap assembly (30) to which a plurality of elastic arm members (17, 18, 19) and a patella bracing pad (15) are attached. The strap also includes an anchor which serves to isolate the patella bracing pad from a counterarm member (19) to allow the dynamic repositioning of the pad (15) when the knee is flexed. The patella brace (10) may be used to facilitate positive diagnosis of patella subluxation whose symptoms may mimic other pathological problems of the knee and, therefore, lead to an erroneous diagnosis. The brace (10) may also be used for treatment and/or to delay or avoid the need for corrective surgery.
Patent CA-2214158-A1 (CA)
Inventor: BLOUIN YVON
IPC: A47C19/00
Filed: 1997-10-20
Abstract: La présente invention se rapporte à un levier à pression négative fonctionnant comme un soufflet, muni de roues, qui lorsque le vide se fait, facilite le déplacement d'un meuble lourd. On peut comparer ce type de levier à une ventouse placée sur une vitre. En faisant le vide à l'intérieure, la paroi de celle-ci s'enfonce pour coller fortement sur la vitre. Plus la surface de la ventouse est grande, plus on devra déployer une force physique importante pour la décoller. Déplacer un fauteuil, par exemple, demande un effort physique important pour une personne normale. C'est en passant l'aspirateur que j'ai associé la force de la ventouse à la difficulté de déplacer un meuble. Si l'on met des roues permanentes à un fauteuil, il se déplace à toute les fois que l'on s'assoie et il est instable, ce qui est assez désagréable. Mais si les roues sont enfoncées sous le meubles et qu'elles sont activées par le système de levier à pression négative via le boyau d'aspirateur, lorsque nécessaire, c'est déjà mieux.

Title: Loop electrodes for electrocautery probes for use with a resectoscope
Inventor: HAHNEN KEVIN F
IPC: A61B18/14
Filed: 1996-04-19
Abstract: An electrocautery probe (112) includes a distal loop electrode (122) mounted between a pair of arms (123, 125) which are joined at their proximal ends to an electrode lead (127), and a mounting sleeve (129) for slidable coupling the probe to the guide tube (14) of a resectoscope (10). The loop electrode is formed with a relatively broad lower surface defining a sharp distal edge (122a) and a sharp proximal edge (122b). The electrode may have a triangular cross section or a cross section which is defined by an upper convex surface and a lower flat surface. Tests have demonstrated that the electrode according to the invention is approximately 90 % more effective in coagulation than the known loop electrodes. It is believed that the sharp distal and proximal edges aid in cutting and focus cautery current to this effect while the relatively broad base serves to enhance coagulation.

Title: Coreless adhesive tape winding mandrel and method
Inventor: JOHNSON DEE LYNN
IPC: B65H18/04
Filed: 1996-05-29
Abstract: A method and apparatus (20) for forming coreless rolls (15) of pressure sensitive adhesive tape involves the use of a mandrel assembly (55) having a specific circumferential tape supporting segment (234) thereon for winding tape. The circumferential tape supporting segments (234) has a tape engaging surface portion (246) that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel (55) to form a tape roll (15), and that is sufficiently pliant to permit ready axial removal of a wound tape roll (15) from the mandrel (55). The innermost wrap (72) of pressure sensitive adhesive tape about the mandrel (55) is masked by an adhesive liner (73). That liner (73) is formed from one portion of a liner/tab strip (123) which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab (76) forms an end tab on the outermost end (75) of the previously formed coreless tape roll (15). The circumferential tape supporting segment (234) of the mandrel (55) is supported on a rotatable shaft (210) and its surface portion (246) may be defined by a plurality of pliant stems (248) extending generally outwardly from the shaft (210) at approximately equal height. The circumferential tape supporting segment (234) may further include a tubular section of material (244) bearing the tape engaging surface portion (246), which may be rotatable about the shaft (210).

IPC: G06K9/72
Filed: 1998-02-17
Abstract: In the past, capturing biometric information was performed by analysing biometric information images for registration on a continual basis or with user intervention - a user views biometric information displayed on a screen and when suitable, accepts same. It has now been discovered that searching for specific limited patterns within an image or within a portion of an image, enables the detection of the presence of an image suitable for registration against biometric templates for user identification. According to the method, an image is captured comprising rows and columns of pixels. A row of pixels from a fingerprint image is scanned to detect a number of ridges and valleys within the row. When a sufficient number exists, the image is considered likely a fingerprint and is captured for registration.

Title: Absorbent article with clean appearance and capacity signal means
Inventor: HENNESSY SHANNON JULIA
IPC: A61F13/15
Filed: 1996-09-13
Abstract: An absorbent article, such as a sanitary napkin, comprising a topsheet, a backsheet, and an absorbent core is described. The absorbent core comprises an acquisition member, a storage/distribution member, and an indicator member.  The absorbent article further has a longitudinally oriented middle region defined by the storage/distribution member and a pair of longitudinally oriented side regions that lie laterally outboard of the middle region. The acquisition member is disposed on the storage/distribution member and the indicator member is disposed, at least partially, in the side regions. The storage/distribution member has a higher capillary suction than the acquisition member such that absorbed bodily fluids are drawn from the acquisition member into the storage/distribution member providing a clean appearance. The capillary suction of the storage/distribution member is also higher than the capillary suction of the indicator member so that the indicator member is not noticeably stained until the absorbent capacity of the storage/distribution member is substantially exhausted thus providing a signal that it is time to change when such staining becomes apparent.

Filed: 1997-04-11
Abstract: A system and method for detecting defects on a painted workpiece surface (B).  The system includes an elongated line of light (112) having a pair of sharp transition zones. The line of light falls onto a moving substrate (S) containing a plurality of workpieces (B) to be inspected. A scanning detector (118) receives light scattered by the workpiece (B) surface. A first scan is performed proximate one edge of the line of light (112) and a second scan proximate the other. A defect on the workpiece (B) produces characteristic shadow or backscatter patterns which vary between the first and second scans.  The shadow and backscatter patterns cause variations in the amplitude of the light detected by the scanning detector (118). The scanned information is then digitally and electronically processed by software which recognizes each defect, and characterizes the defect by type and/or size.
