Patent CA-2522831-C (CA)
Inventor: LINDQUIST BJOERN
IPC: H04L27/22
Filed: 1996-03-01
Granted: 2006-11-28
Abstract: A method for processing a signal modulated with information symbols to account for an additive offset and slope is disclosed. First, an initial estimate of offset and slope is made and hypotheses of all possible values of a sequence of one or more information symbols are then made.      For each of said hypotheses, the associated data symbol sequence is used to make an improved estimate of offset and slope and the improved estimate of offset and slope are stored against each of the hypotheses. For each hypothesis, the improved estimate of offset and slope is used in calculating an expected signal value and a mismatch between a sample of the modulated signal and the expected value is computed. The hypotheses are then sequentially extended by one symbol, the slope and offset estimates are updated and the mismatches are accumulated to form a path metric value for each extended hypothesis, and resolving between said hypotheses based on said path metric values using a Viterbi Sequential Maximum Likelihood Sequence Estimation process to produce a most likely hypothesis of said modulated information symbols substantially unimpaired by said additive slope and offset.

Granted: 2011-11-15
Abstract: A packet data generating method and apparatus for supporting multiple services in a wireless packet data communication system where an MS transmits two or more traffics to a BS on one of a reverse PDCH, a reverse FCH, and a reverse DCCH. To generate a PDU using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, a multiplex option is determined during service negotiations between the MS and the BS. The multiplex option defines a traffic format having a header and a payload including traffic data, and the header includes a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data. A PDU is generated by formatting a reverse traffic to have a header and a payload according to the determined multiplex option.

Title: In situ process to recover heavy oil and bitumen
Inventor: GATES IAN DONALD
IPC: E21B43/243
Filed: 2006-07-21
Granted: 2013-07-02
Abstract: An in situ reservoir recovery process consisting of a horizontal injection well and a horizontal production well to extract bitumen or heavy oil from a reservoir. The process consists of a first phase operated at high-pressure in which steam, hydrocarbon solvent and non-condensable gases are injected into the reservoir and a second phase in which the injected fluids are transitioned to a high content of solvent and non- condensable gas and a reduced amount of steam to maintain a warm zone in the neighbourhood of the injection and production wells. The steam injection is sufficient to promote vapor transport of the solvent into the vapor depletion chamber and maintain the process at elevated temperatures in order to maintain low fluid viscosities in the production wellbore and to achieve preferred phase behaviour of the solvent hydrocarbon and the heavy oil or bitumen. The operating pressure of the process is controlled to prevent losses of the solvent hydrocarbon to the formation and to aid in solvent production to the production well in order for future re-cycling.

Title: Switchgear control apparatus
Inventor: KOYAMA HARUHIKO
IPC: H02H7/26
Filed: 2007-10-30
Granted: 2012-03-20
Abstract: A switchgear control apparatus includes a zero point interval detecting circuit, an interruption time judgment circuit and a reclosing time decision circuit. The zero point interval detecting circuit detects time intervals between successive zero points of a main circuit current. The interruption time judgment circuit judges that interruption time of the main circuit current is time of a zero point immediately preceding a zero point at which a difference between the time interval between two successive zero points and half the period of a commercial AC voltage exceeds a specific value. Upon detecting the gradient of the main circuit current at the interruption time, the reclosing time decision circuit sets reclosing time at a point in phase where the AC voltage has a maximum negative value if the gradient is positive, and at a point in phase where the AC voltage has a maximum positive value if the gradient is negative.
