Abstract
An endless manual control for use in automation systems, such as automated recording consoles, which controls levels and other parameters of audio, video and other signals, by generating, storing, sending and receiving electronic control signals. The control's internal circuitry translates control movements into electronic signals describing the control's movements. These electronic signals, including external electronic signals which are inputed during certain modes of operation, are fed into a circuit for updating the circuit's memory of control levels. When either the minimum or maximum control level extreme is reached, the circuitry triggers a mechanism to stop the manual rotation of the control in the direction which had or would have caused that control level extreme to be reached.
Claims8
An endless belt fader control comprising:
- a housing having an upper surface, said upper surface having an opening formed therein;
- a first pulley and a second pulley disposed within said housing;
- a rotatable belt disposed within said housing and supported by said first pulley and said second pulley, said rotatable belt engaging said first pulley and said second pulley such that movement of said rotatable belt imparts rotation to said first and second pulleys, and said rotatable belt extending substantially along said opening formed within said upper surface of said housing;
- a signal generating means disposed within said housing and being in communication with said rotatable belt for generating electrical signals indicative of said movement of said rotatable belt, said signal generating means being capable of providing said generated electrical signals to a processing unit disposed externally of said housing;
- and
- a locking means for preventing rotation of said belt in a first direction, said locking means being capable of receiving control signals from said processing unit.
A rotary control comprising:
- a shaft;
- a knob mounted to one end of said shaft;
- a signal generating means operatively coupled to said shaft for generating electrical signals indicative of a rotation of said knob, said signal generating means being capable of providing said generated electrical signals to a processing unit;
- a locking means for preventing rotation of said knob in a first direction, said locking means being capable of receiving control signals from said processing unit.
