US Patent 11950580 Automatic line release system for aquatic traps

An example line restraint system comprises a housing, a processor, a motor, a release cam, and a timer. The release cam comprises a stem portion and an arm portion. The stem portion is proximate to the housing and the arm portion may be opposite the stem portion. The stem portion may be rotatably coupled to the motor. The motor may be configured to turn the arm portion of the release cam between an open and closed state. When in the closed state, an overhang of the arm portion at least partially defines a cavity capable of retaining a release line. When in the open state, the release cam opens the cavity to enable release of the release line. The timer may receive instructions from the processor to set a particular time and to trigger the motor to turn the release cam from the closed state to the open state.
