Title: Fiber optic cladding displacement connector
Inventor: WINDEBANK ROBERT W
IPC: G02B6/28
Filed: 1999-12-09
Abstract: Disclosed is an optical fiber displacement connector and method used with a fiber optic cable as an optical tap. The fiber optic cable includes a light carrying center, a cladding and a buffer. The cladding displacement connector has surfaces which can be used for displacing the buffer and cladding to expose the light carrying center. The cladding displacement connector at least partially surrounds the light carrying center of the fiber optic cable. The cladding displacement connectors are formed of an optically conductive material and is insertable into a printed circuit board or an integrated circuit chip. The connector can carry bi-directional and multi-wavelength light signals. The optical signal carried by the light carrying center of the fiber optic cable can be caused to exit the fiber optic cable by displacing the cladding, abrading the cladding, dissolving the cladding, and carving a groove into the light carrying center. The connector is then placed in optical contact with the light carrying center of the optical cable. The connector can also be used with an optical fiber.

Patent CA-2302052-A1 (CA)
Title: Reactive polymer gel actuated pumping system
Inventor: SWATEK MIKE ALLEN
IPC: F04B43/09
Filed: 1998-08-12
Abstract: A subsurface well system contains well bore fluid and a pumping system which is lowered into the well bore on a conduit. The pumping system is supplied with electrical power through a conductor. The pumping system has a chamber, a discharge valve, and an intake valve for admitting the well bore fluid into the chamber. The chamber contains a reservoir that is filled with a reactive polymer gel that undergoes a significant change in volume in response to environmental changes. The gel expands when it is electrically stimulated, thereby forcibly expelling the fluid within the chamber. The gel contracts when it is not stimulated, thereby drawing fluid into the chamber. When electrical current is oscillated through the gel, the expansions and contractions repeat so that a pumping action of well bore fluid is achieved.  The gel may also be formulated to react to an electromagnetic field. The gel of this embodiment contains metallic particles which increase in temperature when exposed to the magnetic field. The temperature increase significantly increases the volume of the gel. Applying electrical current to a coil which surrounds the reservoir causes a magnetic field to pass through the gel, thereby increasing the volume of the gel. When electrical current is oscillated through the coil, the gel expands and contracts so that a pumping action of well bore fluid is achieved.

IPC: B27G19/00
Filed: 2000-04-03
Abstract: An easily engageable and releasable chainsaw bar guard for protecting an individual carrying a chainsaw and for preventing damage to the cutter chain and saw dogs of a chainsaw. The bar guard comprises an elongated stiff hollow sleeve whose interior space is just slightly larger than the bar and chain to be protected. The sleeve has an opening at the proximal end for sliding the sleeve onto the guide bar, and is closed at the other end to protect the end of the bar and cutter chain. A snap-clip mechanism is fixed to the sleeve for releasably latching the proximal end of the guard to the chainsaw. The snap-clip mechanism biases a retaining claw into contact with the chainsaw bar between the nuts on the saw bar attachment/adjustment bolts.      The sleeve and the snap-clip mechanism can be selectively configured to accommodate chainsaw bars of different shapes and dimensions and the spacing of whose guide bar adjustment nuts varies. The guard may optionally be provided with clips, pockets or containers for storing chainsaw tools.

Abstract: An ice cream cone holder and drip collector device (10, 100, 200) includes a sleeve (12, 14) having an open upper end (16). A drip catcher (18, 28) is attached to the sleeve (12, 14) and includes an inner wall (20) that extends downwardly from the periphery of the open upper end (16) of the sleeve (12, 14). An outer wall (22) can be separated from the inner wall (20) by a spacer wall (24), the inner wall (20), outer wall (22), and spacer wall (24) forming the drip catcher (18). Because the drip catcher (18) attaches to the sleeve (12) at the open upper end (16) of the sleeve (12) and the drip catcher (18) provides no surface that is parallel to the vertical plane, a plurality of devices (10) can be intimately stacked one on top of the other and packaged in high density. Alternatively, the same result can be accomplished by a foldable skirt (34) attached to a sleeve (32) which is moveable from a first position wherein the skirt (34) conforms to the shape of the sleeve (32) to a second position wherein the skirt (34) extends outwardly from the sleeve (32) to form the drip collector (38).

Title: A network management system using a distributed namespace
Inventor: PARK JOONHO
IPC: G06F13/00
Filed: 2000-05-04
Abstract: A method and apparatus are disclosed for remotely managing network elements in a distributed computing system. The distributed computing system utilizes a software entity, such as an operating system, to manage the location of, and communication with, distributed resources in the distributed computing system.  A network manager and/or SNMP agents can interact with distributed elements to obtain desired management information independent of the location of the distributed elements. Thus, master agents can communicate with managed network nodes without adhering to the intricate requirements of the SMUX or DPI protocols. SNMP MIBs are implemented as hierarchical file systems, comprised of a tree of file-like objects, that may be accessed through a namespace. The SNMP MIB namespace allows the network manager, master agent and SNMP agents to access each resource, including SNMP MIBs, in a uniform, file-oriented manner. The SNMP MIB namespace of each network node managed by a master agent can be mounted into the namespace of the master agent to create a distributed MIB namespace. The MIB of each managed node is mounted to the MIB namespace of the master agent and appropriate connections through the distributed network are established by the operating system or another software entity.
