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: Interface device, control method for the same, and data storage medium for recording the control method
Inventor: MINOWA MASAHIRO
IPC: G06F3/09
Filed: 2000-02-07
Granted: 2005-09-13
Abstract: An interface device for a printer, a control method for the interface device, and a data storage medium for storing the control method. The receiver part o~ the interface device receives data sent by a host computer, and the transmitter part of the interface device sends received data to the printer through the printer expansion slot to which the interface device is installed. A detector detects whether the printer can receive data. Memory stores received data when the detector determines that the printer cannot receive data. A real-time command transmission controller assures that real-time commands are sent to the printer even when the printer cannot receive other data because the receive buffer is full, for example.

Patent CA-2304214-C (CA)
Title: Internet telephony call routing engine
Inventor: DALTON JAMES PLEASANT GOSSETT
IPC: H04L25/06
Filed: 1998-09-16
Granted: 2006-05-23
Abstract: The present invention discloses a centralized routing engine that is able to assist gateways in making routing decisions for calls being placed in an Ip network environment. Types of calls include voice, fax, video, etc. The routing engine provides significant flexibility to the gateways by allowing the gateways to designate preferences that define operational limits or requirements. A source gateway operator may set preferences such as the maximum price that is willing to be paid for a call, the maximum delay that will be tolerated and the maximum autonomous system hop count that will be tolerated. A destination gateway operator is likely only to be concerned with setting price schedules as preferences. Gateway operators may also set "preference criteria", which define the circumstances in which a certain set of preferences is to be applied.      Based on preferences and preference criteria, the routing engine is able to locate destination gateways that are eligible to terminate a voice over telephony IP call. The routing engine provides a prioritized list of eligible destination gateways to the source gateway. The source gateway then works through the prioritized list and attempts to set up the voice over IP telephony call with each eligible destination gateway, until the call is established.

Abstract: Cette invention se rapporte à un dispositif (30) et à un procédé de stimulation magnétique des muscles, en vue de diagnostiquer et de soulager des troubles respiratoires, tels que l'apnée obstructive du sommeil. On utilise la stimulation magnétique pour stimuler des muscles qui servent à stabiliser les voies respiratoires supérieures d'un individu dont les évènements apnéiques nocturnes sont à mettre en relation avec une diminution du tonus musculaire. A cet effet, un capteur (38) surveille une caractéristique physiologique du patient, une bobine (56) est mise sous tension pour stimuler les muscles appropriés associés aux voies respiratoires supérieures, une source de courant fournit le courant de mise sous tension de la bobine (56), et un système de commande (32) commande l'application de courant à la bobine (56) sur la base de la sortie du capteur (38). Le diagnostic de l'apnée obstructive du sommeil est réalisé par mesure de la compliance du sujet en présence et en l'absence de stimulation magnétique des muscles des voies respiratoires supérieures. Plus la différence est petite entre ces deux niveaux de compliances, plus il est probable que le patient souffre d'apnée obstructive du sommeil.

Title: Method and apparatus for measuring the relative density of a gas
Inventor: PRICE BARRY LEONARD
IPC: G01N25/18
Filed: 1999-01-08
Granted: 2004-03-16
Abstract: Apparatus (2) comprises a chamber (4) to which a gas in question, for example natural gas is supplied through inlet (6) and leaves through outlet (8). The speed of sound SoS at ambient temperature is measured using any suitable method such as electronic control and calculating means (14) and an ultra-sound emitter (10) and an ultra-sound receiver (12). The ambient temperatures T a is observed by temperature sensor (22), and a thermal conductivity sensor measures the thermal conductivity of the gas at two different temperatures above ambient temperature. One value ThC H of the thermal conductivity is measured at 70 .degree.C above ambient and the other value ThC L of the thermal conductivity is measured at 50 .degree.C above ambient. The control means (14) calculates the relative density RD of the gas according to the formula RD = g.ThC H + h.ThC L + i.SoS + j.T a + k.T a2 + 1 where (g, h, i, j, k and 1) are constants.

Abstract: A method and an appara-tus which acquire satellite posi-tioning system (SPS) signals in an SPS receiver. Information on time of day, approximate re-ceiver location, and satellite po-sitions are used to reduce the time to search and acquire sig-nals from one or more SPS satellites. In an example of a method of the invention, a first pseudorange to a first SPS satel-lite is determined, and an ap-proximate location of the SPS receiver is determined. An es-timated pseudorange for a sec-ond pseudorange to a second SPS satellite is determined from the approximate location and a satellite position of the second SPS satellite. The SPS receiver then searches for SPS signals from the second SPS satellite in a range determined by the esti-mated pseudorange. Typically, this method reduces the search time to initially acquire SPS signals from the second SPS satellite, and the estimated pseudorange is not based on a previously determined pseudorang e for said second SPS satellite. In a particular example of the invention, the approximate location is determined from a cell based information source which correlates an identification of each of various wireless cell sites with an approximate location for objects within a cell of a wireless cell based communication system, such as a cellular(or cell based) telephone system. In other examples of the invention , relatively precise time of day information may be used with information indicating satellite positions and information indicating the approximate location to determine an estimated pseudorange for a first SPS satellite to be acquired.
