Title: Power and telecommunications access vending machine
Inventor: DUFF THOMAS M JR
IPC: G07F17/12
Filed: 1998-01-20
Granted: 2002-08-13
Abstract: A vending machine for dispensing power and telecommunications access is disclosed.  The vending machine has a switchable power circuit that receives power from a power source and delivers the power to the customer's equipment via a power connector under the control of a central control unit.  A customer interested in purchasing power or using the telecommunications access makes a payment into the payment processing unit which forwards the payment information to the central control unit.  From time to time the central control unit reports the transaction information to a central computer system via its modem which is connected to a telecommunication channel.          Access to the same telecommunication channel or another channel can be made available to the customer via a switchable telecommunications access circuit which is also under the control of the central control unit.  The customer connects to the telecommunications channel via the telecommunications access connector.  The central control unit provides information on the progress of the vending transaction to the customer via the user interface.  The central control unit determines when the transaction is completed by sensing the cessation of power usage via the power usage detection circuit or via customer action at the user interface.  The vending machine may be incorporated within a storage locker, or may be incorporated with telephones in telephone booths, kiosks, and similar structures.  The vending machine may also be used to dispense electricity, telecommunications channel access and other utilities to buildings and vehicles, including cars, boats and airplanes.

Abstract: A method of operating a multiple cylinder internal combustion engine in a four-stroke cycle. A first amount of fuel is introduced into each of the cylinders (10) earlier than 45 degrees before top dead center of a combustion stroke.  Air significantly in excess of that providing a stoichiometric amount of oxygen is also introduced into each cylinder to produce a first mixture upon introduction of the fuel, which mixture is ignited to produce a first combustion event. Subsequent to substantial completion of the first combustion event, but prior to top dead center in the same combustion stroke or shortly after top dead center in the expansion stroke, a second amount of fuel is introduced into each cylinder without additional air to form a second mixture which is ignited to produce a second distinct combustion event.

The generator device and  the analyzer device are clocked in synchronism,   the clock controlling the generator device and the analyzer device being varied in the same way by a frequency or phase modulator for reducing the influence of narrowband disturbances coupled into the circuit caused by aliasing.
Patent CA-2260541-C (CA)

Granted: 2004-08-10
Abstract: The present invention is directed towards a means to detect and reorder out of order instructions that may violate data coherency. The invention comprises a mis-queue table for holding entries of instruction data, each entry corresponding to an instruction in a computer microprocessor. The instruction data in each entry comprises: i) address information for the instruction; ii) ordering information for the instruction, indicating the order of the instruction relative to other instructions in the mis-queue table; iii) data modification information for the instruction, for indicating a possibility of modified data; and iv) out of order information, for indicating that a newer instruction has completed before the corresponding older instruction to the entry. The invention also comprises an out of order comparator for comparing an address of a completed instruction to any address information entries in the miss queue. If a completed instruction accesses the same address as another instruction, as indicated in the address information in the mis-queue table, and the completed instruction is newer than the matched instruction, the out of order field is marked indicating this condition exists. The invention comprises a modification comparator. This compares addresses from data altering events to those addresses in the entries in the mis-queue table. On a match, the modification field of the corresponding entry is marked to indicate this condition exists. When an instruction entry indicates that the corresponding instruction's data is modified, and that the instruction is out of order, all subsequent instructions are cancelled.

IPC: B62D5/065
Filed: 1997-08-13
Granted: 2005-08-09
Abstract: A motor is stopped when a steering angular speed is not greater than a stop threshold VS and a motor electric current value Im is kept within a motor stop range .DELTA.I for a predetermined time period. The value of a steering torque increases as the motor electric current value Im increases.      Therefore, the motor can assuredly be stopped when the steering torque is small. Further, when the motor is off, the sensitivity for motor actuation with respect to a change in the steering angle is set higher as the value of the steering angle increases.

Title: Lightwave communication systems using semiconductor optical amplifiers
Inventor: CHRAPLYVY ANDREW ROMAN
IPC: H04B10/29
Filed: 2000-02-08
Granted: 2003-10-28
Abstract: Substantially error-free communications is achieved in an optical communication system that includes optical amplifiers by detecting bits transmitted in the amplified optical signal using a detection threshold that is derived as a function of a maximum power level associated with a first bit value, e.g., bit "0", and a minimum power level associated with a second bit value, e.g., bit "1". Importantly, this detection scheme can be used to accurately detect bit patterns in the amplified signal even in the presence of nonlinear distortions caused by gain variations, such as inter-modal distortion and saturation induced crosstalk. In a wavelength division multiplexed (WDM) system comprising semiconductor optical amplifiers, for example, the detection threshold can be set at a level corresponding to P TOTAL/2N, where P TOTAL represents the total power in the WDM signal and N represents the number of optical channels in the WDM signal.  According to another aspect of the invention, the effect of gain fluctuations becomes smaller as the number of channels increase. In particular, a smoothing effect is realized for the total effective saturation power as gain variations decrease as a function of an increase in the number of channels. As such, the performance of a semiconductor optical amplifier according to the principles of the invention approaches the linear performance of fiber amplifiers as the number of channels increases.
