Method for manually controlling direction and speed of disk to produce discotheque type 'scratch' effect by using dynamoelectric detection module that generates control signal in response variation of speed and direction of disk

摘要

The rotation sensor is a dynamoelectric detection module that generates a control signal in response variation of speed and direction of the disk. A touch sensitive control disk (200) may control a digital command selector (515) using a detector (202) and triggering module (204). The detector (202) produces a current signal evoked by the user's touch of the disk (200) to control elements or independent devices of the control device. An Independent claim is included for: (a) a control device
