Abstract: The patent application describes a switching power supply, wherein the supply has a first output voltage, wherein the first output voltage was generated by a first working voltage with a first frequency and a first phase, wherein the supply is adapted to configure the first frequency and/or the first phase in such a way that disturbances m devices powered by the supply are reduced, wherein the disturbances are caused of electromagnetic interferences. In an embodiment the switching power supply is adapted to configure the first frequency in such a way that the first frequency and its harmonies are different from the operating frequency of the powered device.

Abstract: The present invention provides a test tee device for leak testing a pipe line system. In structure, the test tee device includes a tee fitting, comprising a tubular section extending between a first and a second opposing openings axially aligned with each other, a third opening communicating with the tubular section of the tee fitting; wherein the tubular section has a inside diameter greater than the first opening inside diameter and the second opening inside diameter. The present invention can also be viewed as a method for leak testing a pipe line system. The method operates by inserting a test tee fitting, applying a test pressure to the test tee fitting through the third opening; and removing the removable insert, if the test pressure is maintained for the predetermined time.

Abstract: An apparatus and a method of improving performance characteristics of an internal combustion engine is provided which includes electronically coupling a fuel boost controller to a fuel delivery solenoid of a fuel injector. The boost controller measures a timed release of fuel from an activated fuel delivery valve of the fuel delivery solenoid into a cylinder and activates the fuel delivery valve an extended amount of time over a programmed time for injecting additional fuel over the programmed amount into the cylinder to improve the performance characteristics.
