Patent CA-2289501-A1 (CA)
Title: Gyrator with loop amplifiers connected to inductive elements
Inventor: BROWN ANTHONY KEVIN DALE
IPC: H03H11/50
Filed: 1999-03-25
Abstract: A gyrator includes shunt or feedback nodal capacitors and shunt lossy inductors without shunt load resistors. The effective nodal capacitance is reduced by the introduction of the shunt lossy inductors. The inductors act to discriminate against injected power supply noise, resulting in improved oscillator phase noise. The inductors produce less dc voltage drop than the resistive load, so that larger linear oscillation is obtained with improved oscillator phase noise. The gyrator includes an automatic gain control circuit and a tuning control circuit which are separate from each other and fast and slow acting control loops which are augmented with each other.

Patent CA-2295435-A1 (CA)
Title: Linear low noise phase locked loop frequency synthesizer using controlled divider pulse widths
Inventor: RILEY THOMAS
IPC: H03K23/66
Filed: 2000-01-06
Abstract: A method and an apparatus relating to a PLL circuit for frequency synthesizer applications. By using a composite PFD large and small phase variations between a reference signal and the divider output are compensated for. The composite phase frequency detector (PFD) has both a digital phase frequency detector (digital PFD) and an analog phase detector (analog PD) with the digital FFD compensating for large phase differences and the analog PD compensating for smaller phase differences. The PLL automatically chooses between these two components in the composite PFD by controlling the pulse width of the divider output. This is accomplished by synchronizing the dead zone of the digital PFD with the active pulse width of the divider output and by similarly synchronizing the phase detector window of the analog PD to be within both the dead zone of the digital PFD and the active pulse width of the divider output. Thus, during the active pulse of the divider output, the analog PD is operative while during the inactive pulse the digital PFD is operative. By essentially having only one PD active at any time, problems with analog/digital mixed circuits are avoided.

Patent CA-2301339-A1 (CA)
Title: Method and system for identifying a feature on a longitudinally advancing member and marking the advancing member based on the identification
Inventor: MCNEILL STEPHEN RICHARD
IPC: G02B6/44
Filed: 2000-03-17
Abstract: A characteristic feature on a generally longitudinal member is detected as the member is longitudinally advanced on a path extending from a first position to a second position. Based on the detection of the feature on the member and monitoring of the advance of the member on the path, indicia can be applied to a desired position on the member. The detected feature can be an S-Z reversal existing or created on a strand of S-Z stranded optical fiber buffer tubes included in an optical fiber cable which is undergoing cable manufacture along a cabling line. Intensity data values representative of an optical image sample of the strand with the S-Z reversal feature, where the image sample is obtained by an optical radiation detector coupled to the path, are processed for identifying the S-Z reversal feature on the strand. Monitoring the advance of the cable to the marker allows for marking of the strand, or jacketing which has been applied to the strand, at a desired position during advance of the cable on the path.

Title: Reduced keyboard disambiguating system
Inventor: KUSHLER CLIFFORD A
IPC: G06F3/023
Filed: 1998-09-24
Abstract: A reduced keyboard disambiguating system. The keyboard has twelve to sixteen keys, nine of them labeled with numerous letters and other symbols, and those nine plus one more are associated each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting "Select" key, or a key with an unambiguous character interpretation, at the end of each word, delimiting a keystroke sequence that could match any of a plurality of words associated with the same keystroke sequence. Each input keystroke sequence is processed with a complete vocabulary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use.  The vocabulary is stored in a special format that support significant data compression without requiring additional processing. In addition, stems of longer words whose initial letters match the sequence of keystrokes are also presented to the user in order of decreasing frequency of use. If the frequency of the words associated with a stem is high enough, that stem is displayed as the default word object. Activations of an ambiguous key associated with a plurality of punctuation characters are disambiguated from the context of the surrounding keystrokes.

Patent CA-2318061-A1 (CA)
Inventor: FLETCHER DAVID LEE
IPC: C10G45/06
Filed: 1999-10-25
Abstract: A dual functional catalyst is used to produce low sulfur gasoline from olefinic naphthas at relatively low pressure with minimal loss in road octane number. The dual functional catalyst uses a Group VI and/or a Group VIII metal on a suitable substrate for hydrodesulfurization and a zeolite for cracking. One such combination is a Cobalt Molybdenum/ZSM-5 catalyst. At low pressure, the catalytic reaction favors olefin cracking instead of olefin saturation from metals to improve product yields and enhance the octane number.
