Patent CA-2254736-A1 (CA)
Title: Call yourself bert testing of isdn line
Inventor: KENNEDY MICHAEL
IPC: G06F9/445
Filed: 1998-12-01
Abstract: A portable ISDN test set contains test circuitry that is controllably operative to automatically test the ISDN communication capability of an ISDN circuit. In response to a user operating a prescribed input/output element of a user interface of the test set, the test set's supervisory control processor executes a routine that places an ISDN call over a first bearer channel of the ISDN circuit, the first bearer channel  having a  first directory number, through a public switched telephone network to a second directory number associated with a second bearer channel of the ISDN circuit. The ISDN call is thus routed by the public switched telephone network back to the ISDN test set. When the ISDN call is received by the test set, it is automatically  looped  to  the  public  switched  telephone network,  so  that  the  call  is  rerouted  to  the  first directory number associated with the first bearer channel to  the  ISDN  test  set.  When  the  looped back call  is answered, a BERT is conducted over the dual looped bearer channel pair,  thereby testing the full 128 Kbps bearer channel  bandwidth  of  the  ISDN  circuit.  The  automated testing routine includes a subroutine that automatically derives  the  first  and  second  directory  numbers  from respective user-supplied service profile identifiers for the first and second bearer channels.

Title: Method and apparatus for provisioned and dynamic quality of service in a communications network
Inventor: SAKSENA VIKRAM R
IPC: H04L12/70
Filed: 1999-02-24
Abstract: A method and apparatus for providing provisioned and dynamic QoS in a communications network. In one embodiment, provisioned QoS is provided in a network using NHRP by deciding to establish an SVC for a sender and receiver. An NHRP resolution reply containing QoS information is received in response to an NHRP resolution request. An appropriate SVC is then established using the QoS  information. In another embodiment, dynamic QoS is provided in a network using RSVP. A  first RSVP multicast connection tree with a first QoS is established in response to an RSVP request. When a second RSVP request is received, a new tree is created if the QoS in the second RSVP request is not within a threshold range from the QoS of the first tree. If the QoS in the second RSVP request is within the threshold range, a new branch is added to the first tree and no new RSVP connection tree is required.

Title: Systeme d'entree d'air a double mouvement pour les batiments d'elevage
Inventor: PERREAULT JEAN-PIERRE
IPC: A01K1/00
Filed: 1999-09-09
Abstract: La qualité de l'air à l'intérieur des bâtiments d'élevage est un point qui influence grandement la rentabilité d'une ferme. En effet, une mauvaise ventilation provoquera souvent des maladies pulmonaires qui amèneront un ralentissement de la croissance ou même la perte des animaux. Ceci est particulièrement vra i pour les élevages de volailles et de porcs où la densité des sujets dans les bâtisses est singulièrement élevée.  Bien qu'un changement d'air approprié soit en tout temps nécessaire, la problématique change en fonction des saisons. En hiver, on recherche un appo rt d'air frais de l'extérieur sans pour autant créer des zones froides où des animaux seront inconfortables. En été, surtout en période chaude et humide, en plus d'un changement d'air important, il faut créer un mouvement d'air qui permet de rafraîchir les animaux.

Abstract: There is provided a composition suitable for implantation in soft tissue (for example at or around a body orifice) in order to augment the volume of soft tissue. The composition described comprises particles of a, preferably watersoluble, biodegradable glass in a suitable carrier medium, such as glycerol. The particles, which are desirably irregularly shaped, may have an average particle diameter of from 50 .mu.m to 2000 .mu.m, preferably 50 .mu.m to 300 .mu.m. By injecting the particles into soft tissue, for example the bladder submucosa, it is possible to bulk up the soft tissue where this is required. This procedure can be applied to treat conditions such as vesicoureteric reflux. Additionally the procedure could be used cosmetically.
Patent CA-2286838-A1 (CA)
Title: Resonant reflector for improved optoelectronic device performance and enhanced applicability
Inventor: MORGAN ROBERT A
IPC: H01L31/0232
Filed: 1998-06-10
Abstract: Optoelectronic devices such as VCSEL and RCPD devices that have integrated resonant reflectors. The integrated resonant reflector may be made conductive so that bias current can pass therethrough. This may allow more flexibility in the design of the VCSEL and RCPD devices. Since making the resonant reflector more conductive typically reduces the overall reflectivity of the resonant reflector, the resonant reflector may be provided in combination with a Distributed Bragg Reflector (DBR) mirror to achieve the desired overall reflectance for a VCSEL or RCPD design. A broad bandwidth resonant reflector may also be provided. The bandwidth may be sufficiently wide to increase the reliability of data communication between such devices, and may be sufficiently narrow to maintain adequate mode control and mode stability.  These devices may be used to support polarization-, space- and/or wavelength-division multiplexing applications.

Ce courant en dents de scie est transformé en un train d'impulsions correspondant à la tension de ligne à partir de laquelle on détermine la tension de ligne.
Patent CA-2289377-A1 (CA)
Inventor: HUNDEBY DAVID R
IPC: A01B73/06
Filed: 1999-11-10
Abstract: An agricultural implement is provided with a forward folding tool bar that is pivotally mounted on the draw bar for rotation about a transverse pivot axis as part of the folding and unfolding of the tool bar. The tool bar is provided with a tower apparatus having a passageway therethrough for alignment with pivot linkages for providing a floating movement of the pivotally mounted wing members with the wing fold actuators forming a rigid link in the pivot linkages. An unfold finger is mounted on the draw bar where the tower mechanism would be positioned upon the rotation of the tool bar into an intermediate transport position such that the unfold finger is positionable within the passageway through the tower apparatus. The unfold finger is spring-biased and incorporates lost movement slots to allow the unfold finger to yield when the passageway is blocked as the tower apparatus is moved over the unfold finger. Once engaged within the tower apparatus, the unfold finger provides a stop against which the pivot linkages push when the wing fold actuators are utilized to unfold the wing members, but is retracted from the passageway whenever the tool bar is rotated into a working position.
