Abstract: An encoder module with a sliding assembly comprises a cover, a disk, a reading head, a bottom plate, and a sliding unit; wherein in assembly, the disk is installed at an upper front side of the bottom plate; the reading head is installed upon a front side of the sliding unit; the sliding unit is pushed into a lower hole of the bottom plate so that a front end of the sliding unit exposes from the lower hole of the bottom plate; in that the reading head serves to read signals from the disk; finally the cover covers upon an outer side of the bottom plate, the sliding unit and the reading head so as to form as an encoder module with a sliding assembly.

Abstract: A method of making a plastic code wheel/code strip by: depositing a chrome-aluminum film on a plastic substrate having a transmittance greater than 90%, a transmittance greater than 90%, a heat resistance to at least 120° C. and a thickness smaller than 0.5 mm; forming a photoresist layer on the chrome-aluminum film; covering a patterned film strip on the photoresist layer; radiating the patterned film strip with a collimated light source to expose the optical grating pattern into the photoresist layer; removing the patterned film strip and the non-exposed photoresist from the chrome-aluminum film; etching the chrome-aluminum film; removing the photoimaged photoresist so as to obtain a semi-finished product having an optical grating pattern; and then stamping the semi-finished product into a finished product according to a predetermined shape.

Abstract: An apparatus for detecting a phase of an input signal includes: a phase detector unit for detecting the phase of the input signal referring to a plurality of clock signals having different phases and for outputting a plurality of phase detection results, wherein each of the phase detection results represents a candidate phase of the input signal and corresponds to one of the clock signals; and a phase decision unit, coupled to the phase detector unit, for determining the phase of the input signal according to the phase detection results.

Abstract: A computer mouse having a resilient soft pad with massaging function, comprises a front part and a rear part removably fitted onto said front part. The front part can be separated from the rear part if wish. When the rear and front parts are connected with each other, the power circuit will be in an open status, thus the massaging head projecting from the upper face of the rear part will not vibrate, and then can be used as a resilient soft pad for lessening the fatigue of the user's palm. When the front part is separated from the rear part, the rear part can be used as a massager to massage the body of the user who is fatigued with operating the mouse.

Abstract: A receiver set for desktop and mobile phones, removable from a handset or a mobile phone set, includes an extendable ear hook and an extendable speaker element. While extending the ear hook and the speaker element, the receiver set can be used as an earphone. Therefore, during operation of the receiver set, user's both hands can be free for handling other tasks. While storing the receiver set onto the handset or the mobile phone with both the ear hook and the speaker element retrieved, the receiver set can perform as a conventional receiver. It is obvious that the receiver set of the present invention provides more flexibility in using a phone.
