A self secured housing includes a frame with openings, a first cover disposed on a first side of the frame and mechanically coupled to a plurality of semi flexible first fingers that are arranged for disposal in the openings with some of the semi flexible first fingers having a concave interlocking detail, and a second cover disposed on a second side of the frame and mechanically coupled to a plurality of semi flexible second fingers that are similarly arranged for disposal in the openings. The second fingers are further arranged to urge a corresponding one of the first fingers toward a side of the opening and engage the convex interlocking detail with the concave interlocking detail, thereby securing the frame between the first cover and the second cover.

Self secured housing for electronics

A frequency synthesizer (51) arranged in a phase locked loop fashion to provide an output signal with a preselected frequency within a controlled lock time from a voltage controlled oscillator (51), having: a phase detector (55) with a controllable gain, that provides an error signal proportional to the controllable gain and corresponding to a phase difference between a reference signal and a feedback signal, an adapt circuit (121) for setting the controllable gain to an adapt value (205), and a tracking circuit (123) for setting the controllable gain to a tracking value (207) by adjusting the controllable gain in a predetermined and controlled fashion from the adapt value (205) to the tracking value (207).
