Title: System integrating active and simulated decisionmaking processes
Inventor: COLLINS JOHN E
IPC: G06Q10/06
Filed: 1995-03-02
Abstract: SYSTEM INTEGRATING ACTIVE AND SIMULATED         DECISIONMAKING PROCESSES          Abstract of the Disclosure A system that integrates active and simulated decisionmaking processes generates decisions in response to events representing changes in a domain model, and updates the domain model according to the decisions.  The system includes a real-time mode for generating recommendations in response to real-time events, and a simulation mode for generating recommendations in response to simulated events.  The simulation mode is capable of running on either randomly generated domain events or real-time domain events captured during the real-time mode.  In addition, the simulation mode does not require development of a separate domain model for simulation. Rather, the simulation mode may use the contents of a domain model established during the real-time mode. Integration of an active decisionmaking tool with a simulation tool thereby eliminates the cost of constructing a separate simulation model, and avoids invalidation of the contents of the simulation model over time.

Patent CA-2149848-A1 (CA)
Title: Direct digital synthesis component test
Inventor: GIBSON GREG S
IPC: G01R31/26
Filed: 1995-05-19
Abstract: A "component test" function is provided in a low-power, portable test instrument like a digital multimeter.  A test stimulus waveform is synthesized digitally, and a digital trigger signal from the synthesizing circuitry is used to trigger acquisition ofmeasurement data.  A single-channel front end acquires voltage scan data over one cycle of the test stimulus waveform following the trigger point.  Current scan data is later acquired through the same acquisition circuitry beginning at the same trigger point relative to the start of a later cycle of the stimulus waveform, so that the voltage and current scan data, although acquired separately, are very closely synchronized relative to the stimulus waveform, as a result of which they maintain their phase relationship. Stored voltage and current scan data are aligned accordingly and concurrently displayed so as to form a Lissajous pattern on a small display. Theinvention thus provides improved component test capability in a small, portable instrument, including graphic display of test results.

Patent CA-2161117-A1 (CA)
Inventor: WHITLOCK WILLIAM E
IPC: H03F3/45
Filed: 1994-04-22
Abstract: An audio line receiver which tolerates a wide range of balanced and unbalanced source impedances with a minimal deterioration of the line receiver's common-mode rejection ratio. The line receiver includes a differential amplifier (50) with input amplifiers (52, 54) on each input of the differential amplifier. The input amplifiers are typically operation amplifiers (A8 or A9) connected for unity gain, but also having two bias resistors (R17 and R19, or R18 and R20) connected in series between the input terminals of the input amplifiers and ground. A capacitor (C1 or C2) connected from the output of the operational amplifier to a node between the two series connected bias resistors prevents the low impedance of the bias resistors from significantly degrading the line receiver's common-mode rejection ratio.
