A reflecting body is disposed at a lower end of the operating stick, and the optics module has a light source and an optical sensor. The light source projects light onto the reflecting body and the light is reflected to generate a reflected image into the optical sensor. The operating stick is moved to drive the reflecting body, such that the reflected image into the optical sensor is changed to generate the vector signal.

Abstract: A wireless transmission circuit enabling modulation of RF power amplification includes a signal processing circuit for outputting a signal that is modulated and then amplified at a cascade power amplification circuit including a plurality of power stages, and is then wirelessly transmitted to and received by a computer system. The wireless transmission circuit includes at least a power-setting unit for controlling a specific number of power stages included in the power amplification circuit to be used in the power amplification of the modulated signal. When a wireless input device employing the wireless transmission circuit is used within a short transmission distance, a lower transmission power is selected via the power-setting unit; and when the wireless input device is used at a long transmission distance, a higher transmission power may be selected to achieve the remote transmission. The wireless input device could therefore have extended battery life.

Abstract: A support mechanism for a computer peripheral device includes a housing accommodating a base within the housing, and a supporting post having a first end coupled to the base. The base has a pivoting sleeve and couples to the supporting post at a first position, and the pivoting sleeve engages with the supporting post such that the housing is rotatable to force the pivoting sleeve and the supporting post to rotate. The pivoting sleeve can move along an axial line of the housing, and the housing can be pivoted about the top of the pivoting sleeve together with the supporting post. Therefore, the housing can carry out multi-direction-movement, or so-called sphere-like movement relative to a leg coupled to the second end of the supporting post.
