    摘要： An uninterruptible power supply (“UPS”) has a phase-controlled rectifier coupled to a source of AC power and having an output providing a DC bus, the output of the phase-controlled rectifier coupled to an inverter. A first controller generates a firing angle for the rectifier and a fuzzy logic controller generates a firing angle for the rectifier. In an aspect, the rectifier is controlled by the firing angle generated by the first controller during normal operating conditions of the UPS and the rectifier is controlled by the firing angle generated by the fuzzy logic controller during abnormal operating conditions of the UPS. The abnormal operating conditions can include loss of a direct DC bus voltage measurement and or a period of time after the UPS experiences a large load change. In an aspect, the firing angle generated by the first controller is compared to the firing angle generated by the fuzzy logic controller and a rectifier fault condition determined to exist when the two firing angles differ by at least a threshold amount. In an aspect, the first controller is a PI controller.

    摘要： An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The control has an indicator that reveals resistance to rotation and/or reduction in flow. Material that has been processed by the cutter is aspirated through the tubular body for disposal. The control enables rotation of the rotatable element only following application of a predetermined level of vacuum.

    摘要： An image-forming device includes a processing member in the form of a brush/drum processor. The processing member includes a rotatable vacuum drum with a surface that is adapted to receive an exposed photosensitive medium. Vacuum applied to the drum is effective to hold a medium on the drum. The processing member also includes a pad member that faces the outer surface of the drum. The pad member includes micro-members that resemble a brush and are adapted to contact the media while the media is held on the drum. The pad member can be moved in an oscillating manner to cause the micro-members to contact the imaging surface of the media held on the drum with a pressure that is sufficient to rupture microcapsules in the media.

    摘要： A system, method and computer program product for managing database query execution using control point policies that can (1) defined, (2) applied to a sphere of database operation, and (3) evaluated at run time to determine whether a policy action should be taken. A control point policy “definition” can include the specification of (1) an operational control point to which the control point policy is applied, (2) a control point policy filter that determines whether the control point policy will be implemented, and (3) a control point policy action to be implemented pursuant to the control point policy. The “application” of a control point policy can include the specification of (1) a scope of database management system operation, (2) a level representing the precedence of the control point policy relative to other control point policies, and (3) an operational environment for control point policy execution. The “evaluation” of a control point policy can include evaluating the filter specification of an applied control point policy when the associated control point is reached to determine whether the policy action should be taken.
