Title: Automatic Determination and Tuning of Pico-Cell Topology for Low-Power Wireless Systems
Inventor: RUTLEDGE PHILIP ANTONY
IPC: H04B7/26
Filed: 1995-06-07
Abstract: A method of using the existing radio resources to automatically determine the current cellular topology is described. Wireless base stations are placed into a mode where they can transmit a signal which can be received by all of the base stations in range of the transmitting base station. Each base station in the system serially broadcast a signal which is received by all other base stations within the range of the transmitting base station. Each of the receiving radios determines the RSSI (Received Signal Strength Indication) at which they received the transmitted signal. The RSSI values are used to determine which base stations are physically co-located into cells and then determine the relative locations of the cells to each other. A method is also described by which the wireless system monitors the mobility traffic of subscribers and makes use of this information to improve the operation of the system. As the user makes use of the mobility features of the system by making and receiving wireless calls, the mobility patterns of the users are tracked and fed into an algorithm which determines and updates to the central wireless configurations. Hence, over time the system is able to determine which cells are more likely to be involved in handover situations.
Patent CA-2166877-A1 (CA)
Title: An apparatus for applying additional momentum
Inventor: DONALDSON WILLIAM KENNETH
IPC: E02D7/06
Filed: 1994-07-08
Abstract: The present invention provides apparatus for applying additional momentum to the movement of a body (1) adapted to reciprocate or flex through a substantially linear or arcuate path, notably for increasing the impact velocity of a linearly travelling weight upon an object (3), which apparatus comprises means (4) for retracting the body from its rest position, notably for retracting a weight from the point of impact between the weight and an object located at the rest position of the weight, means (5) for biassing the body towards its rest position, notably for urging the weight towards the object so as to impart additional impact velocity to the weight as it travels towards the object, characterised in that a) the means for biassing the body towards its lest position is an elastic polymeric material which is retained under tension or compression when the body is in its test position; and b) the biassing means is one which undergoes strain crystallisation.     The invention also provides a method for breaking or penetrating a surface using the apparatus of the invention.
Patent CA-2167439-A1 (CA)
Title: Vibration damping apparatus
Inventor: MUTAGUCHI MASAO
IPC: B61B12/04
Filed: 1996-01-18
Abstract: A vibration damping apparatus includes a frame having a rail member and end plates at longitudinal ends of the rail member.  The frame is a hollow box-shaped element or a hollow tubular element.  The rail member defines a downwardly arcuate surface.  The frame is fixed on a vibrant structure.  A vibration damping body is movably located on the rail member such that it can naturally oscillate thereon upon vibrations of the structure.  An  energy of vibration of the structure is transferred to and absorbed by the damping body so that the vibration of the structure is attenuated.  By appropriately determining  a radius of curvature of the rail member, a natural period of the damping body is set to be equal to that of the structure.          First and second magnets are mounted on the end plates and third and fourth magnets are mounted on opposite end faces of the damping body.  The first and third magnets have the same polarity and the second and fourth magnets have the same polarity.  Therefore, a repulsive force is generated when the first and third magnets approach each other or when the second and fourth magnets approach each other.          Consequently, collision between the damping body and the frame ends is prevented.

Abstract: In an ignition assembly for a flare vent having an open terminal end for ventingwaste gases, a hollow tubular stripper is located ad jacent a generally upright exterior wall of the flare vent and has a lower opening and an upper opening proximate to the terminal end of the flare vent. A conduit for diverting some of the waste gases from the flare vent to the stripper is located below both the upper opening of the stripper and the terminal end of the flare vent. A pilot has an ignition end to ignite the diverted waste gases in the stripper to produce an ignition flame at the upper opening of the stripper, which in turn ignites the waste gases exiting the terminal end of the flare vent. The pilot is housed in a sleeve having an open first end for receiving the pilot and an open second end for exposing the ignition end of the pilot to the waste gases in the stripper. The sleeve is insertable into the stripper and, when inserted, allows air flow through the stripper to produce the ignition flame and to cool the sleeve. A track is attached to the exterior wall of the flare vent for moving the sleeve and pilot between an inoperative position near the base of the flare vent and an operative position near the terminal end of the flare vent. In the operative position the second end of the sleeve and the pilot are located within the stripper below the stream of waste gas entering the stripper through the conduit.

Title: Improvements in and relating to containers of particulate material
Inventor: EASON STEPHEN WILLIAM
IPC: A61J7/00
Filed: 1995-05-16
Abstract: A method of producing a container (201, 231 350) having a plurality of apertures (e.g. 202, 232, 352) each containing a respective dose of powdered material, such as a medicament, involves placing an empty container in a position in which its apertures communicate with a reservoir (216, 84) of powdered material. The material is then passed, for example by the flow of gas, from the reservoir into the apertures to fill the latter, and the container is then separated from the reservoir and the apertures are optionally sealed with sheet material (204, 206, 321, 323). Since the apertures are filled, their volume determines the amount of each dose which therefore does not have to be measured prior to introduction into the apertures. The container may comprise a rigid or flexible plate and in latter case can be subsequently rolled into the form of a cylinder for use in an inhaler. Apparatus for performing the method, and an inhaler for use with a cylindrical container, are also shown.
