Abstract: A television receiver includes apparatus for stabilizing an on-screen character display by which the deflection signal source is controlled for operating in a free-running mode, substantially unaffected by signal variations on the sync input line, rather than in a synchronized mode when sync is unreliable or otherwise undesirable. As another feature, the deflection signal source is caused to operate at substantially the same frequency in either mode.

Abstract: System and apparatus for monitoring vibrational and other detected aspects of a machine. Transducer outputs are scanned through the use of a microprocessor, the memory components of which retain pre-determined set point information. The channel representing a given transducer output is displayed visually on the apparatus for 5 second intervals in combination with a linear form of disply showing monitored transducer values as well as set point values. In the event of detected threshhold level warnings or the like, additional visual indicators representing both system and channel status conditions are energized. The system includes a small, hand-held programmer by which any of a broad variety of functions may be readily entered into the memory of the processor through the simple manipulation of a single potentiometer. During the programming procedure, the values being inserted are displayed on the noted bar chart. Preferably, the chart is present as a linear array of 50 LEDs.
