Patent CA-2247886-A1 (CA)
Inventor: STENSTR M B HUGO
IPC: A61B6/12
Filed: 1997-02-14
Abstract: A device for direct, visual estimation of dimensions of measurement objects that are difficult to reach, such as organs and foreign articles within human and animal bodies. The invention is founded on the fact that the human eye gives a strikingly good size apprehension when comparing a measurement object with a similar thing of known dimension close to that of the measurement object. The comparison can preferably be carried out on an X-ray picture in which a measurement object as well as a comparison body are reproduced close to each other and preferably on the same scale. Means are provided for fixing the comparison body at the surface/exterior of the human or animal body. The comparison body (10) is confined by a series of surfaces of revolution with different sizes within an interval matched to the dimension interval of the measurement objects. The form of the surfaces of revolution is matched to the form of the measurement objects. Thus cylindrical surfaces of revolution are chosen if the measurement object is cylindrical and spherical surfaces of revolution if the measurement object is globular.

Patent CA-2250423-A1 (CA)
Inventor: BYERLY DAVID J
IPC: B05C5/02
Filed: 1998-10-13
Abstract: A liquid dispensing device including a body generally having an air passage and a liquid passage. A valve seat element is connected to the body and a needle is mounted for movement within the body with respect to the valve seat element. First and second connected needle guides receive respective portions of the needle in a manner inhibiting sideward movement thereof. The first needle guide allows flow of liquid through the liquid passage adjacent the first needle guide to the dispensing orifice when the needle is moved away from the valve seat. The first needle guide is connected to the valve seat by way of a press fit and is connected to a second needle guide by way of another press fit. The connected needle guides are likewise press fit into a bore in the body. These connections all aid in maintaining close tolerances and excellent alignment of the needle. A liquid seal is generally disposed between the first and second needle guides and prevents liquid from entering the air passage. The needle may be moved by pressurized air acting against a piston and the needle may be normally closed by a spring return mechanism when the pressurized air has been shut off. A pivotal force transfer element associated with the spring return mechanism reduces side load on the needle.

Title: Resonant tag and method of manufacturing the same
Inventor: HABERGER CHARLES C JR
IPC: G08B13/24
Filed: 1997-04-25
Abstract: An RF EAS tag (10) includes a substrate (12) with a conductive element (14) positioned on a face surface (18) thereof and having electrically inductive properties. A capacitive element (20) is positioned on the face surface (18) and has electrically capacitive properties wherein the inductive (14) and capacitive (20) elements are operably coupled together to form a resonant circuit which resonates when an electrical signal of a predetermined resonant frequency is applied to the tag (10). The capacitive element (20) comprises a dielectric ink (22) substance having a high dielectric constant for producing the desired resonant circuit on a single face surface of the substrate.      An alternative tag (50) comprises a substrate (52) with a conductive layer positioned thereon and a gap (56) formed in the conductive layer exposing a portion of the substrate. This forms a slotline waveguide shorted at both ends. A high dielectric constant ink substance (58) is then deposited in the slot. This greatly reduces the wavelength in the waveguide allowing an RF frequency 1/2 wavelength resonant line to be made of a practical length.

Patent CA-2255971-A1 (CA)
Title: System and method for bypassing data from egress facilities
Inventor: LEWIS SHAWN M
IPC: H04Q3/00
Filed: 1998-12-14
Abstract: An open architecture platform bypasses data from the facilities of a telecommunications carrier, e.g. an incumbent local exchange carrier, by distinguishing between voice and data traffic, and handling voice and data traffic separately. An SS7 gateway receives and transmits SS7 signaling messages with the platform. When signaling for a call arrives, the SS7 gateway informs a control server on the platform. The control server manages the platform resources, including the SS7 gateway, tandem network access servers (NASs) and modem NASs. A tandem NAS receives the call over bearer channels. The control server determines whether the incoming call is voice traffic or data traffic, by the dialed number, and instructs the tandem NAS how to handle the call. Voiced traffic is transmitted to a switch for transmission from the platform. Data traffic is terminated at a modem NAS, where it is converted into a form suitable for a data network, such as a private data network or an Internet services provider (ISP). The converted data is sent by routers to the data network. The data network need not convert the data, as the function has already been provided by the platform. In lieu of a conversion, the modems can create a tunnel (a virtual private network) between a remote server and the data network.

Abstract: Cette invention permet d'appliquer une tarification moins élevée dans le cas où, au début d'un appel, la cellule de localisation d'un abonné appelant (MS-A) ou d'un abonné appelé (MS-B) appartient à un ensemble de cellules spéciales (CS). D'après cette invention, le critère de facturation est remis à jour au début de l'appel et durant ce dernier. Si un abonné sort de la zone d'une cellule de réseau public et passe dans l'ensemble de cellules spéciales (CS), les informations relatives à la cellule vont se propager jusqu'au centre de commutation mobile (MSC) de l'abonné appelé. Le MSC et/ou le point de commande des services (SCP) vont comparer ces informations relatives à la cellule à l'ensemble des cellules spéciales (CS), puis établir que la nouvelle cellule de l'abonné appelé appartient à ces cellules spéciales (CS), ce qui permet de modifier la tarification. Les informations portant sur le type de cellule modifiée chez l'abonné appelé, sont transmises au centre de commutation mobile (MSC, étape 3) de l'abonné appelant.
