Patent CA-2152408-A1 (CA)
Inventor: KING TODD L
IPC: F16K31/06
Filed: 1995-06-22
Abstract: A method for remotely controlling flow of gaseous fuel to a burner having an electrically operated electromagnetically actuated modulating valve. The electromagnetic actuator comprises a coil having about one thousand turns of fine wire disposed proximate an annular permanent magnet. Either the magnet or coil may be attached to a moveable valve member which has a resilient poppet biased to close on a valve seat to shut off gas flow. Upon energization of the coil, a magnetomotive force is generated and moves the poppet off the seat to permit flow. Increased current flow in the coil proportionately increases opening of the poppet and movement of a metering member which throttles flow. When the poppet is fully open, flow is reduced to minimum metered level. A single user operated, remotely located potentiometer can be used to effect theproportional control of flow to the burner. In the preferred embodiment the metering member is cylindrical with a varying area grove or recess. In another embodiment, the metering member is a reversely conically tapered member throttling in a conically tapered metering passage.

Title: Method for Identifying Untestable & Redundant Faults in Sequential Logic Circuits
Inventor: ABRAMOVICI MIRON
IPC: G11C29/56
Filed: 1995-09-25
Abstract: A method of identifying redundant and untestable faults in a sequential logic circuit. A lead in the circuit is selected and the circuit is analyzed to determine which faults would be hypothetically undetectable at a given time frame if the selected circuit lead were unable to assume a logic 0 at a starting time frame, and which faults would be hypothetically undetectable at the given time frame if the selected circuit lead were unable to assume a logic 1 at the starting time frame. Faults that would be undetectable at the given time frame in both hypothetical cases are identified as redundant and untestable faults. This analysis may be repeated for each of a plurality of time frames in a range of time frames which includes the starting time frame. Faults whose detection would not be possible if the selected lead were unable to assume a given value at the starting time frame may be determined based on a sequential implication procedure comprising the propagation of uncontrollability indicators and the backward propagation of unobservability indicators. An uncontrollability indicator for the given (0 or 1) value is assigned to the selected circuit lead and is propagated through the circuit and/or through a range of time frames according to a predetermined set of propagation rules. Unobservability indicators are generated in the circuit at various time frames based on the uncontrollability indicators, and these unobservabilityindicators are then propagated backward through the circuit and/or backward through the range of time frames, also in accordance with a predetermined set of propagation rules. The hypothetically undetectable faults are then defined based on the resultant indicators and their corresponding circuit leads and associated time frames.
