Title: Generic method for customization of dhcp options
Inventor: PAYEUR JOEL
IPC: H04L29/12
Filed: 2001-06-05
Abstract: The Dynamic Host Control Protocol (DHCP) is a text-based protocol that functions over the Internet Protocol layer. The main use for this protocol is to configure rebooting networking equipment. DHCP servers can assign dynamic IP addresses to DHCP clients from a pool of addresses, or can assign static addresses manually assigned by network administrators. Along with its assigned IP address, a DHCP client is subject to receive a plethora of other useful configuration information.      DHCP information, called options in DHCP lore, are typically registered with the IANA (Internet Assigned Numbers Authority), and can have virtually any format for their data field. The present invention describes a generic way of adding new options to a DHCP client, by specifying the data type for the option. This allows easy customization of DHCP clients.        Typical examples of this optional information are the local subnet mask and the local router's IP address.

Des écrans à message variable fournissent aux automobilistes des informations courantes sur les places de stationnement disponibles. Le système peut identifier avec précision le véhicule en stationnement quel que soit son emplacement. Le système permet également d'utiliser divers critères de recherche pour localiser par ordinateur des véhicules présents dans le parc de stationnement. Le système peut informer automatiquement de la présence ou de l'absence d'un véhicule en fonction du taux d'occupation du parc ou de l'heure. Un dispositif de prévention du vol de véhicules peut assurer la protection de n'importe quel véhicule en stationnement dans le parc de stationnement.
Patent CA-2363192-A1 (CA)
Inventor: WINDHEUSER JAMES E
IPC: A61M29/02
Filed: 2000-11-15
Abstract: The present invention relates to a multi-size catheter for use in biliary endoscopic procedures. The multi-size catheter comprises an outer diameter defined by a plurality of superimposed peelable layers. The peelable layers allow the multi-size catheter to function as a single operator exchange catheter without the need, and additional expense, of an endoscope sheath. Before positioning the multi-size catheter within the working channel of an endoscope, the peelable layers may be selectively removed in order to obtain an outer diameter for the catheter that is less than, but approximate to, the inner diameter of the working channel of the endoscope. The resulting fit eliminates the potential for a guidewire to slip out of the guidewire channel and become pinched between the catheter and the endoscope working channel. With an incorrect fit, a pinched guidewire would restrict the desired movements of the both guidewire and the catheter.

Title: Method and multi-purpose apparatus for control of fluid in wellbore casing
Inventor: LAUREL DAVID F
IPC: E21B33/14
Filed: 2000-04-26
Abstract: A downhole apparatus is described as having an upper mandrel (320) shearably connected to a lower mandrel (360). A sleeve (300) is shearably connected within the lower mandrel (360).  The operation of the apparatus involves dropping a first small diameter ball (70) from the earth's surface. The ball (70) travels through the upper mandrel (320) and settles into the sleeve (300). By increasing pump pressure at the earth's surface, the lower mandrel (360) is separated from the upper mandrel (320) by shearing. By further increasing the pump pressure, the lower mandrel (360) can be pumped down to the bottom of the tubular string against a float collar or other plug landing surface.  When it is desired to separate the upper mandrel (320) from the tubular string, a second larger ball (68) is dropped from the earth's surface and is seated within the upper mandrel (320). By further increasing the pump pressure, the upper mandrel (320) is separated from the tubular string.

Patent CA-2391029-A1 (CA)
Inventor: EICHE MICHAEL
IPC: C01B3/34
Filed: 2002-06-19
Abstract: Systems and methods for accurately calculating a steam-carbon ratio in a reformer or the like are shown and described. In one embodiment, a control valve regulates the amount of water entering the process side of a heat exchanger upstream of the reformer. A steam/process outlet directs steam from the heat exchanger to the reformer. A level control device operates the control valve to maintain the water at a constant level. A meter upstream of the heat exchanger measures the amount of water entering the heat exchanger. By maintaining a constant water level in the process portion of the heat exchanger, the reading on the meter equates to the amount of steam directed from the heat exchanger to the reformer or vaporizer. With this reading, the steam-carbon ratio at the reformer can be accurately counted. In another embodiment of the present invention, a process gas inlet incorporates an elongated body extending at least partially through the process portion of the heat exchanger. Openings spaced apart along the length of the body distribute the process gas along the length of the heat exchanger. In still another embodiment of the invention, a plurality of dividers is spaced apart along a width of the process portion of the heat exchanger. The dividers are positioned to receive the process gas as it rises from the process gas inlet, and to disperse the process gas along the width of the heat exchanger.
