Title: Method for the sampling of biphase coded digital signals
Inventor: PILZ AXEL
IPC: H03M5/12
Filed: 2000-07-13
Granted: 2008-12-16
Abstract: The invention relates to a method for the sampling of biphase coded digital signals by reception means which have at least one signal input having switchable signal edge sensitivity or at least two signal inputs having different signal edge sensitivity for the reception of such signals. The signals to be received are sampled precisely once per data bit, namely during the transmission of the first half-bit. The signal edges (Fl-F5) of each bit are utilized for synchronizing the signal input with the control signal and for detecting transmission errors. Each signal sampling (S1-S5) is followed by a time window (At) within which the reception of the signal edge of the present bit is expected and evaluated as permissible. The signal edge sensitivity of the at least one signal input is set as a function of the sampled logic level of the first half-bit of the respectively transmitted bit of the signal.

Patent CA-2317206-C (CA)
Inventor: MEYER CHARLES
IPC: F16B7/04
Filed: 2000-08-31
Granted: 2004-05-18
Abstract: The device is a swivel clip or swivel prong with a relatively rotatable swivel and base elements. The swivel element rotates about a shaft which passes through an aperture in the base element.      The swivel clip is initially formed in one piece by molding windows in an upper portion of the swivel element which are opposed to molding windows in a lower portion of the swivel element (that is, alternating around the periphery of the shaft). The windows meet in the base member, forming the swivel shaft, the swivel aperture and the internal gates as a single piece. Subsequently breaking the internal gates provides vestiges which support the swivel shaft within the aperture. Radially oriented upwardly extending inverted V-shaped support boss formed on the swivel and base elements position the swivel and base elements with respect to each other.

Title: Fitment having removable membrane
Inventor: MOODY RODGER A
IPC: B65D25/42
Filed: 1999-03-31
Granted: 2008-09-09
Abstract: A fitment (16) for use as a pour spout has a flange which is secured around a hole in a container. The spout projects outwardly from the container and has a removable interior membrane (32). A horizontal pull ring (39) is attached to the membrane. Pulling the ring removes the membrane by fracturing the tear line (36) at the juncture of the the membrane and the spout. A screw-threaded cap snaps over the spout. A tamper-evidencing band frangibly connected to the lower edge of the cap engages the exterior of the spout so that the cap cannot be removed without breaking the frangible connection. During delivery to the interior of a container, the fitment is detachably secured to a spud (73) by various means. The spud may be frictionally retained in the fitment below a centrally located membrane, or it may be secured to the spout by means of downward projections from the fitment.

Abstract: A method of recovering from a restart procedure in a mobile switching center (MSC) in a radio telecommunications network having a home location register (HLR) that maintains subscriber profiles and a MSC that maintains temporary subscriber records associated with the subscriber profiles in the HLR. The MSC maintains the temporary subscriber records in the MSC during the restart procedure, and flags each temporary subscriber record in the MSC that went through the restart. The HLR flags each subscriber profile in the HLR that fails an attempt to update an associated temporary subscriber record in the MSC during the restart procedure. When an access attempt is received in the MSC that requires use of a temporary subscriber record that is flagged, the MSC requests the HLR to send any changes to the flagged temporary subscriber record. The HLR then determines whether the subscriber profile associated with the flagged temporary subscriber record in the MSC is flagged in the HLR. If the subscriber profile is not flagged, the HLR sends a message to the MSC indicating that there are no changes to the flagged temporary subscriber record. However, if the subscriber profile in the HLR is flagged, the HLR sends to the MSC, the changes stored in the flagged profile which then update the flagged temporary subscriber record in the MSC. The flagged subscriber profile and the flagged temporary record are then reset.

Abstract: A device and a method for simply and accurately evaluating performance of fuel cells have been provided. Hydrogen gas and carbon monoxide gas are caused to flow into a sample holder where an electrode catalyst sample is laid, and the amount of carbon monoxide gas discharged therefrom is detected.    The amount of carbon monoxide gas adsorbed by the electrode catalyst sample is calculated based on the amount of supplied carbon monoxide gas and the amount of detected carbon monoxide gas. The output voltage of a fuel cell is calculated based on a correlation between calculated amounts of carbon monoxide gas adsorbed by the electrode catalyst and output voltages of the fuel cell.

Abstract: A cross connect physical layer switching system is integrated into a central office and facilitates delivering data services, such as digital subscriber line (DSL) service, to subscribers over a shared data and voice line. The cross connect physical layer switching system may be placed between a splitter and the shared line to allow a remote test unit to be controllably connected to the shared line to permit testing; of the shared line by a competitive local exchange carrier (CLEC). By placing the physical layer switching system in the CO, both the CLEC and the incumbent local exchange carrier (ILEC) have full access to the test head (RTU) and full spectrum testing of the line. This allows test access to continue to be done remotely as in an unshared line environment.

Abstract: An electrical crimp connector comprises a metallic crimp barrel adapted to receive the bared end portion of an electrical conductor and a heat-shrinkable polymeric sleeve in which the crimp barrel is received. The insulating sleeve is comprised of an ionic polymer derived from the polymerization of an .alpha.- olefin and an ethylenically unsaturated carboxylic acid , a proportion of whose acid groups have been reacted to create ionic carboxylates of metal ions. The ionic polymer sleeve has high impact toughness, high abrasion and chemical resistance, high resistance to splitting by crimping tools, high degrees of flexibility and transparency, and a relatively low heat shrink temperature, making it more suitable for use in such connectors than sleeves comprised of other materials such as polyamides or polyolefins.

Title: Tensioning idler
Inventor: SERKH ALEXANDER
IPC: F16H7/08
Filed: 2001-07-31
Granted: 2007-10-23
Abstract: The invention comprises a tensioner having a linear motion. A pulley (2) is journaled to a housing (4). A bearing (7) is used to slidingly join the housing and a base. The bearing constrains the housing, and therefore the pulley, to move along a predetermined path. The housing also comprises an arcuate damping surface that interacts with a frictional or damping band (6).  A torsion spring (11) concentrically engages the frictional material band (6), pressing it in to engagement with the arcuate damping surface as the housing moves in response to an impulse or force from the pulley. As a belt load impulse causes the housing to move along the predetermined path, a contact between the damping band and the base causes the spring to further press the frictional damping material against the housing arcuate surface, thereby damping movement of the housing. Further, an axis of the pulley is offset from a centerline of the bearing. As the housing moves, a couple is created between the housing and the base acting through the bearing. The force of the couple create a frictional force between the bearing surfaces, further damping a movement of the housing and thereby a movement of the pulley.
