Abstract: A harmonic-rejection modulation device is provided, which includes a phase splitter, a low pass filter, and a modulator. Based on a square wave, the phase splitter generates a plurality of unfiltered local oscillating signals having phase angles of 0°, 30°, 90°, 120°, 180°, 210°, 270° and 300°, respectively. The low pass filter filters the high frequency components of the unfiltered local oscillating signals to generate a plurality of local oscillating signals having phase angles of 0°, 30°, 90°, 120°, 180°, 210°, 270° and 300°, respectively. The modulator modulates a baseband signal with the local oscillating signals, wherein the third harmonics of the local oscillating signals are eliminated by the modulation process of the modulator.

Abstract: A retractable cable mouse includes a casing, a cable reel member, a connector and a sliding member. The connector is coupled with the cable reel member and in contact with the sliding member. When the sliding member is moved to a first position, the connector is accommodated within the casing. When the sliding member is moved to a second position, the connector is pushed by the sliding member to be exposed outside the casing. At the same time, a perforation of the casing is blocked by sliding member, so that the external dust or foreign material fails to be introduced into the internal portion of the casing.

Abstract: A retractable cable mouse includes a casing, a cable reel member, a connector, a sliding member, and an elastic element. The connector is coupled with the cable reel member and contacted with the sliding member. The elastic element is contacted with the sliding member and coupled with the casing. When the sliding member is moved to a first position, the connector is stored within the casing, and the sliding member is sustained against elastic element, so that the elastic element is compressed. When the sliding member is pulled out of the casing, the compressed elastic element provides an elastic force. In response to the elastic force, the sliding member is moved to a second position. Meanwhile, a perforation of the casing is blocked by sliding member, so that the external dust or foreign material fails to be introduced into the internal portion of the casing.
