Patent CA-2175927-A1 (CA)
Inventor: NEWMAN LAWRENCE E
IPC: H02K15/00
Filed: 1994-11-30
Abstract: To produce a slack condition in a lead wire (24, 26) that extends from a stator coil (20, 22) to a terminal receptacle (40, 42) mounted on the stator core (12), the lead wire is bent over a wire guide finger (124) adjacent the terminal receptable (40 42). This increases the length of the lead wire segment between the coil and the terminal receptacle (40, 42) so that the lead wire (24, 26) will be somewhat slack. This also materially decreases the tension on the lead wire where it enters the receptacle, and avoids the abrupt, wire-weakening, right-angled bend resulting from the present practice. A method and an apparatus are provided for appropriately positioning the wire guide finger.

The present invention provides for an amplitude phased keyed digital communications system including an adaptive baseband equalizer, a digital symbolrecovery circuit in accordance with the present invention, and a quadrature demodulator. The adaptive baseband equalizer receives amplitude phased keyed signals and outputs in-phase and quadrature digital amplitude values corresponding to the received amplitude phased keyed signals. The digital symbol recovery circuit comprises a programmable addressable random access memory that stores a plurality of eight bit words comprising decoded symbol sets of the received amplitude phased keyed signals, and outputs the decoded symbol sets in response to addresses corresponding to the in-phase and quadrature output signals. The quadrature demodulator processes the decoded symbol sets and outputs recovered amplitude phased keyed symbols corresponding to the received amplitude phased keyed signals. Eight bit I and Q amplitude values address 256 x 256 memory locations in the memory of the digital symbol recovery circuit. For example, at each memory location, a seven bit word, for example, is stored. The first four bits define a 4-tuple for the decoded symbol. The fifth bit is a bang-bang phase bit or carrier tracking bit. The sixth bit is a bang-bang automatic gain control bit. The seventh bit is a false lock indicator bit.

Title: Method for communicating with a voice response unit over a cellular telephone network
Inventor: KOVLAKAS STEVE
IPC: H04M17/00
Filed: 1996-12-18
Abstract: This invention overcomes the disadvantages of the prior art by providing a voice response unit that communicates rapidly and directly with a metered cellular telephone network with minimum human intervention.  The rapid communication is achieved by knowing the question or prompt posed by the voice response unit and preparing a response which is speed dialed to the voice response unit. The voice response unit also calculates a check sum to determine if there is an error in the information transmitted to the voice response unit.  The check sum may be the total of the absolute value of the request code, account number, serial number, access code and amount desired to be added to the cellular phone divided by ten.  If, the check sum calculated by the voice response unit is not divisible by ten, the voice response unit knows that the information it received is incorrect.  Then, the voice response unit would ask for the information it received to be retransmitted at adifferent rate of speed.

Title: Series compensator inserting real and reactive impedance into electric power system for damping power oscillations
Inventor: SCHAUDER COLIN D
IPC: H02J3/18
Filed: 1995-12-14
Abstract: A series compensator (11) for damping power oscillations in an electric power transmission system (1) includes a switching power converter (13) which injects a voltage into the transmission line (5) having a phase angle relative to transmission line current which is controlled to provide reactive compensation and to inject virtual real impedance into the line. The switching power converter (13) is a dc to ac converter which is capable of injecting virtual real impedance into the transmission line by virtue of the fact that it has a power exchange device (27) connected to its do terminals (29). Where the power exchange device (27') is a resistor (37), the switching power converter (13) is capable of absorbing real power during surges in power on the line (5). Alternatively, the power exchange device (27) is a storage device (31) such as a battery bank or a super conducting magnet, in which case the switching power converter (13) can provide both virtual positive and negative real impedance.
