Patent CA-2210673-A1 (CA)
Inventor: WOLF ERICH H
IPC: A61F2/82
Filed: 1997-07-24
Abstract: The present invention is a stent for insertion into an artery or other vessel. The stent is formed from a series of tubular shaped bands each formed with a first end which overlaps a second end. The overlap between the first and second ends is variable and allows each band to move between a contracted configuration and a fully expanded configuration which are within the elastic limits of the band. Each band includes a plurality of receivers and a first tab on a first edge of the band to secure each band at or near the fully expanded configuration and allow the stent to conform to the contours of the vessel. The bands are distributed along a substantially common axis to form a tube interconnected by a pair of elongated strips. In use, the stent is placed over a balloon catheter and compressed to adopt the contracted configuration. The stent is maintained in the contracted configuration by a retainer. The balloon catheter and stent are then advanced through a placement catheter to a target site where the balloon is partially inflated to free the stent for expansion to an equilibrium configuration. The balloon may then be more fully inflated to further expand any of the bands in the stent to suit the needs of the patient. The balloon is then deflated and removed, leaving the expanded stent to support that target site.

Title: Method and system for identifying fault locations in a communications network
Inventor: SHAH JASVANTRAI C
IPC: H04J3/14
Filed: 1996-06-07
Abstract: All nodes (12-24) on a malfunctioned communications circuit (42A) of a communications network are enabled to identify the location of the fault (92) causing the circuit malfunction. Upon detecting an incoming signal impairment on the circuit (402), each node (12-24) on the circuit first assumes that the failure is on the segment (42) of the circuit immediately upstream thereof, and accordingly sends an identifier (410) of that fault location to its downstream nodes (18-24). Each node (12-24) periodically repeats sending its identifier (410) to its downstream nodes (18-24). A node (12-24) that has sent its identifier at least a predetermined number of times without receiving a similar identifier from another node upstream thereof (406) or without having detected a normal signal during all that time is determined to have sent out an identifier that correctly identifies the fault on the communications circuit (414). If, on the other hand, a node (18-24) receives a fault location identifier from a node (12-16) upstream thereof before it has completed sending its identifier a predetermined number of times (418), then that node would stop sending its own identifier downstream. And upon receiving the same fault location identifier from an upstream node (12-18) a predetermined number of times, that node further recognizes that the received identifier represents the correct location of the fault (420).

Abstract: A pile and/ or post pounder utilizing a tracked floating anvil and having a continuous loop lift means for lifting a tracked hammer is disclosed. The pounder is adapted to be transported on, and powered by the hydraulic system on any mobile construction equipment. The tracked floating anvil ensures that the post will be impacted sqarely on each strike of the hammer. It also safely holds the post in position when pounding is commenced. The continuous loop lift means driven by a variable speed hydraulic motor facilitates hammering at as high a rate as possible. The post pounder comprises: a frame; an upright track mounted on the frame; a floating anvil positioned in the track, adapted to seat on the post; a sliding hammer positioned in the track positioned above the floating anvil; and, a continuous loop lift means carried by the frame to lift and drop the sliding hammer. In use the frame is lifted to seat the floating anvil on a post positioned for driving; and then the hammer is reiteratively lifted in the track and dropped until the post is sufficiently driven into the ground.
Patent CA-2227273-A1 (CA)
Title: Transmission of data on multirate networks
Inventor: MUNDAY PETER ROBERT
IPC: H04W88/18
Filed: 1996-07-17
Abstract: Mobile radio units (11, 21) communicate with their respective base stations at a lower bit-rate than the conventional switching rate of a fixed network. When communication is made between a mobile user (11) and a conventional subscriber to the 64 kbit/s PSTN system, or between such a conventional subscriber and a receiver (21). Such calls are identified by mobile to mobile recognisers (17 and 27) which identify characteristic bit streams and handle calls appropriately. The first mobile to mobile recogniser (17) is located at the fixed side of the air interface (14) and, for a normal call routes the call to the digital to A-law transcoder (15). The mobile to mobile recogniser (27) identifiers calls coming from the 64 kbit/s switch (10), and for a normal call routes the call to the high bit-rate digital to A-law transcoder (26) as described above with reference to Figure 2. If a call is established between two mobile users (11, 21) the mobile to mobile recogniser (17) identifies such a call, for example by number recognition in the call set up phase and diverts the signal received over the air interface (14) to a bit stuffer (18). The bit stuffer (18) creates (64) kilobit frames from (16) kilobit frames by providing three null bits for every bit received over the air interface. The null bits may be random numbers, but preferably include a recognisable pattern which can be detected by a second mobile to mobile recogniser (27). By "bit stuffing" in this way a 64 kbit/s signal can be generated from a 16 kbit/s signal with minimal signal processing and without the need to transcode to A-law and back. The mobile to mobile recogniser (27), may be controlled, either by recognition of the identity of the calling number, or by recognition of the characteristic pattern of null bits in a bit-stuffed signal generated by bit stuffer (18), and routes the signal to bit stripper (28) instead of to the high bit digitalto-A-law transcoder (26). The bit stripper removes the null bits and transmits only the signals making up the original 16 kbit/s signal. These are then transmitted over the air interface (24) to the low-bit-rate to A-law decoder (23), and thus to the A to D converter (22) and the listener (21).

Title: Power stealing solid state switch for supplying operating power to an electronic control device
Inventor: KOMPELIEN ARLON D
IPC: H02M5/293
Filed: 1998-01-26
Abstract: A power stealing circuit provides operating power for a environmental control such as a thermostatic control while controlling the current in a power supply line to a load in response to the cycling output of the environmental control. A pair of power FETs are connected to the series power terminals, and the gates are controlled by logic and phase timers. FETs are turned off at the end of a phase, while a small amount of power sufficient to operate the control and circuitry is diverted to a power storage circuit, then the FETs are turned back without substantial interruption to the load. A preferred embodiment uses a bidirectional charge pump to transfer power between low- and high-voltage power storage circuits. The circuit can operate with symmetrical or nonsymetrical AC or DC loads.

Title: Positioning control for combined milling machine and internally positioned grinding wheel
Inventor: LUNN GARFIELD R
IPC: B24B41/047
Filed: 1998-02-25
Abstract: An improved tool includes a milling tool rotatable about an axis, and a coaxially mounted grinding wheel positioned slightly axially towards a workpiece from the milling tool. The milling tool provides rough finish on a workpiece, and the grinding tool follows, providing finish grinding. The present invention recognizes that the grinding tool will be deflected away from the workpiece at high speed due to centrifugal forces. The present invention positions the milling tool relative to the grinding wheel at a location that compensates for the expected deflection of the grinding wheel, and achieves the desired amount of grinding.  In further features of this invention, the phenomena of deflection of the grinding wheel due to increased speed is utilized to compensate for wear on the milling tool.
