摘要： A displacement gauge or gauge for detecting misalignment (3) employs four magnetic coils (24N, etc.) 90.degree. apart, (each) energized by an oscillator (36N, etc.), to sense the dislocation of a machine part, such as a post (12), near their center. A nominal position of the part (9 or 12) relative to a reference component (6) of the machine is first established. Subsequent displacements are detected and are indicated if they exceed a predetermined threshold magnitude.Signals from the four coils are combined in such a way that the magnitude of the radius of a displacement of the part (9 or 12) from the nominal position is ascertained approximately, irrespective of the direction of displacement from the reference part (6). The combination signal (at 64) is the greatest of (a) the absolute value of a north/south displacement signal, (b) the absolute value of an east/west displacement signal, and (c) 0.707 multiplied by a combination signal which is the sum of the north/south and east/west absolute value signals. During setup the gauge is self-aligning on the post.

摘要： An electronic A.C. switch which affords either "normally open" or "normally closed" type of operation to a connected alternating current source and load in accordance with which of two alternate terminals such source and load are connected in addition to a third common terminal. Its operation is automatically inhibited in the event the A.C. source and load are connected to both of such alternate terminals simultaneously. It can be used with a wide variety of electrical sensor devices for effecting its operation between either of its normal and opposite circuit states.

摘要： A new and improved method and apparatus is disclosed for detecting a target location with respect to an inductive tank circuit. A sensing field such as an electromagnetic field is established having an amplitude which changes in value due to the presence of a target in the sensing field. A first energy level is provided to maintain the field at an amplitude. A second energy level is provided to achieve a value for the field within the predetermined amount of time after initiation of the field.
