Title: A position determination method for use with analog cellular system
Inventor: GILHOUSEN KLEIN S
IPC: H04Q7/36
Filed: 1995-03-24
Abstract: A method for determining the location of a mobile unit within a cellular system. A synchronized signal at a common phase is generated at each base station in a system.      The mobile unit transmits a signal tone. Each base station compares the phase of the signal tone to the common phase of the synchronized signal to produce a phase offset. A system controller compares the difference between the phase offset of a first base station and the phase offset of a second base station and determines the difference in distance between the first base station and the mobile unit and the second base station and the mobile unit defining a hyperbolic curve of locations. The system controller determines the intersection of the first and second hyperbolic curves thus determining the location of the mobile unit. The mobile station transmits the signal tone on a second channel that is distinct from a first channel over which user information is transmitted. The mobile station switches to the second channel in response to a request by a base station to the mobile station.
Patent CA-2468358-A1 (CA)
Inventor: MIGNACCA PETER J
IPC: E02D5/38
Filed: 2004-06-18
Abstract: A pile is installed in a drilled hole in the ground by inserting a tube extending to the bottom and providing on the bottom end of the tube a bottom shoe for compressing material at the bottom of the hole. A drive tool attached to the upper end of the tube applies downward compression and reciprocating rotation forces to the tube. A hammer by-passes the drive tool to apply impact forces to an upper surface of the shoe at the bottom of the tube acting to drive the shoe in downward movement so that the shoe slides downwardly relative to the tube. A radial surface of the shoe causes compressive forces on the material at the bottom of the hole and blades on the radial surface when reciprocated back and forth by the tube cause break up of the compressed material to allow repeated compression and significantly increased supported loads on a pile which is applied with the tube removed and is supported on the shoe.

Patent CA-2480581-A1 (CA)
Inventor: LAN KANG
IPC: H01Q1/24
Filed: 2004-09-03
Abstract: It is highly desired both for mobile communication industry and public safety systems, that a whip antenna can work in a very wide VHF band with good impedance matching, for example from 138MHz to 174MHz with VSWR=1.5:1. However, seldom products are available in the market. In this invention, the broadband is obtained by the matching circuit integrated on two PCBs without modifying the whips. The PCBs are small enough to be mounted inside a protective housing as small as regular mobile antenna base. Two different matching circuit topologies are proposed for different whip lengths, i.e., for quarter wavelength antennas and half wavelength antennas. The first one is composed of one air coil and three capacitors in series, and one air coil and one capacitor in shunt. The whip is serially connected to a capacitor. Then an air coil and a capacitor are connected to the circuit in shunt to extend the bandwidth. A series capacitor and a shunt capacitor are then added to improve the impedance matching. A series resonant network composed of an air coil and a capacitor is used to further improve the bandwidth. It is known that as the whip length is increased up to around half wavelength, the antenna becomes more difficult to be matched in a wide band. In the second topology, a T-type transforming network composed of two series air coils and one shunt capacitor is used to obtain impedance match around the center frequency. Then a shunt resonant network composed of one air coil and one capacitor in parallel, and a series resonant network composed of one air coil and one capacitor in series are used to extend the bandwidth. A  shunt capacitor is used to further improve the impedance matching. Although the present invention is described to VHF band antennas working in 138~174MHz, it is straightforward to apply the present invention to other frequency band by adjusting the whip length and circuit element values.
