Title: Intramedullary bone plug
Inventor: CARN RONALD M
IPC: A61B17/56
Filed: 1997-01-03
Abstract: A bone plug (10) is provided for insertion into the medullary canal of a patient's bone during orthopedic surgery, wherein the bone plug restricts or prevents passage of bone cement introduced under pressure into the medullary canal. The bone plug comprises a generally cylindrical member formed from a biocompatible material such as polyethylene, and having sets of distal (24) and proximal fins (26).  The distal fins are defined by a spiral thread set at an angle to extend distally, to bend to accommodate the shape of the medullary canal and thereby anchor the bone plug by biting into patient bone, whereas the proximal fins flex during plug insertion to extend proximally and thereby seal against bypass flow of bone cement past the bone plug. An insertion tool is disclosed for use in placing the plug during a surgical procedure, such as hip arthroplasty.

After listening to the pre-defined responses, the recipient selects a particular response which is then forwarded to the creator of the original voice mail message.
Patent CA-2221694-A1 (CA)
Title: Method and apparatus for switching between redundant hardware in a wireless data communication system
Inventor: PARK DANIEL J
IPC: H04L69/40
Filed: 1996-05-21
Abstract: A wireless communication system uses transmitted data signals to monitor and control redundant modulator hardware. A modulator unit signature identifying the modulator unit currently transmitting data is emebedded into each data frame carried by the transmission signal. Each modulator unit (42 or 44) can then independently monitor the transmission signal to determine which modulator is currently transmitting data. Each modulator unit (42 or 44) then monitors the transmission signal in case the modulator unit actively generating the transmission signal fails. In a failure situation, the active modulator unit disconnects itself from the transmission circuitry while the backup modulator unit independently connects to the transmission circuitry to begin active transmission.

Patent CA-2230922-A1 (CA)
Inventor: MCMEEKIN LINDA J
IPC: A61F13/49
Filed: 1996-08-20
Abstract: This invention provides absorbent products, having a permeable cover made of a microperforated fibrillated thermoplastic film that has improved properties such as intimate, but nonoccluding contact with the body, yet providing comfort and resilience and immediate fluid acceptance and distribution. The cover is characterized by having non perforate regions and perforate regions, the perforate regions having a plurality of microholes defined by a network of fiberlike elements, the perforate regions being, at least in part, at elevations that are higher than the nonperforate regions. The perforate regions are caused to be at higher elevations by methods such as tensioning the cover or by partly adhering the cover to the absorbent body of the product or by combinations thereof. The microholes may be of different sizes and shapes. One embodiment provides an absorbent product having a cover with apertures larger than microholes, alone or in addition to microholes, and greater open area, so that viscous fluids such as menses can readily flow through, the cover having for example at least one group of large apertures or at least two different size groups of apertures. Additional improvement of fluid acceptance and distribution properties is obtained by corona discharge treatment of one side of the film before microperforating and by treating the microperforated film with surfactant.

Title: Procede de sequencage genomique continu
Inventor: SENAPATHY PERIANNAN
IPC: C12Q1/68
Filed: 1996-07-16
Abstract: L'invention concerne un nouveau procédé de séquençage génomique contigu qui permet le séquençage contigu d'un ADN très long sans qu'il soit nécessaire de sous-cloner celui-ci. Ce procédé fait appel à la technique de base de PCR mais, selon ce procédé, il n'est plus nécessaire, comme c'est le cas avec la technique de PCR classique, de connaître deux amorces pour effectuer le séquençage contigu, la connaissance d'une seule amorce étant suffisante. Grâce à la présente invention il est possible d'amplifier par PCR un ADN à côté d'une séquence connue avec laquelle une amorce peut être réalisée sans que le site de liaison de la seconde amorce présent dans la séquence inconnue soit connu. Le procédé selon l'invention peut donc être mis en oeuvre pour effectuer le séquençage contigu d'un ADN très long tel que celui contenu dans un clone de chromosome artificiel de levure ou YAC ou un clone de cosmide, sans qu'il soit nécessaire de sous-cloner des fragments plus petits, selon la technique de PCR standard. Ce procédé peut également être mis en oeuvre pour le séquençage d'un chromosome ou d'un génome entier sans qu'il soit nécessaire de le sous-cloner. Cette technique peut également être appliquée pour l'amplification d'un ADN inconnu dans lequel aucune séquence n'est connue, et pour le séquençage de cet ADN.

Abstract: A cushioning conversion machine (20) for converting sheet-like stock material (22) into a three-dimensional cushioning product (P) including a device (400; 400'; 500; 600; 600'; 700) which controls the width of the strip and which may be selectively adjusted to change the width of the strip. By selectively setting the device (400; 400'; 500;  600; 600'; 700), a cushioning product of a desired width may be produced. For more sophisticated packaging needs, the stock material may be converted into a first portion of a certain width, the device adjusted, and then the stock material may be converted into a second portion of a different width whereby the cushioning product will have continuous portions of different widths. The converting and adjusting steps may be performed sequentially and in such a manner that the cushioning product has discrete sections of different widths, or alternatively, the converting and adjusting steps may be performed substantially simultaneously and in such a manner that the cushioning product has a gradually tapering shape.

Title: Aiming and compositional means for head--worn camera
Inventor: MANN STEVE
IPC: G02C9/00
Filed: 1998-12-31
Abstract: A means of aiming a head-worn wearable camera is described. It is assumed that a head-worn camera will have some form of power supply associated with it, so that the power supply can also be used to provide a plurality of light rays into an eye of the wearer of the apparatus, resulting in an electrically powered viewfinder. The wearable viewfinder may be used by itself to give the wearer a feeling that the world is seen through a camera, so that a camera may not-be required as part of the apparatus. The wearable viewfinder is constructed so that it appears to others as ordinary eyeglasses. Some embodiments look just like ordinary unifocal eyeglasses, while other embodiments have the appearance of bifocal eyeglasses, trifocal eyeglasses, progressive eyeglasses, or reading glasses. Because of the wearer's ability to constantly see the world through the apparatus, the apparatus behaves as a true extension of the wearer's mind and body, giving rise to a new awareness of photographic composition at all times, whether shooting or simply imagining the process of shooting.
