A bus-line protector preventing the bus-lines within a computer casing from moving around and being damaged by metal components is disclosed. The bus-line protector has a base plate and at least one wing plate, wherein the base plate has at least one notch and at least one fold line. The wing plate is extended from the fold line of the base plate and comprises at least one insert extended from a periphery of the wing plate. After placing the bus-lines on the top surface of the base plate, the wing plate is inclined inwardly at the fold line and covers the base plate. Then, the insert comprising a T-shaped protrusion is securely engaged into the notch of the base plate. As a result, the bus-lines are fixed in location and are thus protected by the bus-line protector of the present invention.

A sensing device including a base, a pillar, an arm, a sensing element and a driving module is provided. The base has a supporting surface suitable for supporting the object. The pillar is disposed on the supporting surface. The arm has two ends and a pivot portion between the two ends. The pivot position is pivoted to the pillar along an axis substantially parallel to the supporting surface. The sensing element is disposed on the arm and located between an end and the pivot portion. The sensing element is located between the base and the object. The driving module is disposed between the arm and the base. The driving module drives the arm to pivot relatively to the pillar along the axis, and the sensing element moves toward or away from the object as the arm is pivoted.

The present invention discloses a multi-level output signal converter, which is connected to an audio amplifier. The audio amplifier comprises a comparing/measuring device, an encoder and an output unit. The multi-level output signal converter comprises a timing processing unit and a multi-level converter. The timing processing unit is connected to the comparing/measuring device and the encoder. The timing processing unit includes a plurality of flip-flops and a timing summing element. The flip-flop receives a first signal from the comparing/measuring device and outputs the first signal to the timing summing element. The encoder converts the first signal into a second signal. The multi-level converter is connected to the encoder and the output unit. The encoder transmits the second signal to the multi-level converter, and the multi-level converter thus outputs a third signal to the output unit.
