Abstract: A positioning method and probe system for performing the same, a method for operating probe system, and a method for utilizing probe system to produce a tested semiconductor device are provided. The positioning method is used for positioning a plurality of probe assemblies with an under-test device including a plurality of pads, each of the probe assemblies have at least one probe tip that corresponds to each of the pads for contact, and at least one fixed probe assembly and at least one motorized probe assembly are defined among the probe assemblies during a positioning process.

Abstract: A portable electronic system is provided. The portable electronic system includes a wearable device and a host. The wearable device includes a connector and a magnetic-reed switch. The connector includes a first detection point. The host detects a voltage at the first detection point and a state of the magnetic-reed switch when the host performs a detection operation. The host performs at least one of a plurality of functional operations according to a detection result of the detection operation.

Abstract: An audio system of a tablet personal computer and the speaker orientating method thereof are provided, wherein the audio system comprises at least two speakers mounted on a frame of the tablet personal computer, an angle detector mounted on the frame, an audio driver used to drive the speakers, and an audio-adjusting device. The audio driver can adjust the sound field of each speaker in accordance with a set of audio parameters. The angle detector is used to generate positional data as the frame is rotated relative to the ground. The audio adjusting device is used to renew the audio setting in accordance with the positional data to make the speakers provide an audio stereophony substantially equal to the predetermined stereophony.
