摘要:
Systems and methods are described herein for selectively loading code elements included in a plurality of software entities comprising a target software entity and one or more reference software entities to facilitate analysis of the target software entity by a code analysis tool, such as a static code analysis tool. In one embodiment, all of the code elements in the target software entity are loaded while only those code elements included in the reference software entities that are determined to be most important from a dependency standpoint are loaded. The loaded code elements may be used to obtain suitable definitions of the code elements included in the target software entity for the purpose of code analysis.
摘要:
Tests can be categorized as important with respect to ensuring software functions correctly as a function of one or more rules that define importance. The rules can be configurable to enable control of categorization. Further, tests categorized as important can be highlighted in some manner, for instance by displaying important tests in a group designated for such tests.

摘要:
A method and system for controlling an electromechanical actuator assembly and measurement of actuator position via two drive wires to the actuator assembly. The system includes sensing the changing inductance of the actuator through the electrical drive line and associating the sensed inductance with a corresponding position of the actuating member.

A method and apparatus for solenoid driver control of high speed solenoid actuators which includes supplying a high regulated level of acceleration current to operate the actuator, monitoring and controlling the current requirements of solenoid actuation, automatically reducing the solenoid current at a rapid rate to a lesser level of regulated solenoid hold current for the remaining duration of actuator operation, and rapidly reducing the solenoid current between acceleration and holding levels and for rapid solenoid release. Current is controlled at the different levels using switch mode power control techniques for power efficiency.

摘要:
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 the proportional 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.

A solenoid operated proportional control expansion valve having a tubular armature guide of non-magnetic material disposed externally of the valve blocks with a magnetic pole piece welded on the end of the tubular guide. A plastic encapsulated coil is received over the guide. The armature guide has a flange therein which in one embodiment is welded to a second flanged tube threaded into the valve blocks. In other embodiments the guide flange is directly mechanically fastened to the valve block. A cup-shaped pole frame is received over the coil for completing the magnetic flux loop about the coil.
