Abstract: An adjustable rear view mirror extension apparatus that attaches to a standard existing rear view mirror found in most automobiles and other motor vehicles. The apparatus has a mirror, a mirror frame to secure the mirror, a plurality of lateral supports to position the mirror on the frame, and a flexible mirror retainer to releasingly retain the mirror in the mirror frame. There is a mirror frame support that allows the mirror to rotate on a vertical axis and a rotating device to allow the mirror to rotate on a horizontal axis. The rotating device has a housing comprising two sections. The two sections are adjustably connected to adjust the tension of the insert spring which controls the ease of movement of the mirror around its horizontal axis. The rotating device has a first and second surface with a plurality of radial bosses and grooves, respectively, included are an insert, spring and insert gripping device to restrict rotation.

Abstract: An analyzation apparatus for ignition systems that has a pulse detector circuit that generates and converts an AC signal into a DC signal, filters unwanted signals and allows the user to adjust the amplitude of the signal to accommodate differing ignition systems. A pulse stretching circuit is included to increase the duration of the signal and an analog driver circuit is included to convert the signal received by it to a linear voltage suitable for driving two LED display circuits. The LED circuits are connected in parallel with the driver circuit and the visual display of the LED circuits show a display proportional to the amplitude of the signal received from the driver circuit. The LED displays show the amplitude of the signal. The LED circuits have diodes the prevent current flow between adjacent LED's of the adjacent LED circuits. The apparatus includes a function switch to select the LED circuit desired and to interrupt power to the apparatus. A portion of the elements are enclosed in a case.
