Abstract: A fishing device is provided which in a single structure can be used to perform a plurality of fishing operations, such as a motorized jigging operation, a casting operation, a trolling operation and a motorized jigging trolling operation. The device imparts a lifelike swimming action and oscillatory movement to lures, to baits and to live or plastic minnows. This imparted action and movement is caused by an electric motor in the handle which revolves an eccentric striker arm to deflect a length of line positioned in the path of the striker arm. Two separate control means permit the device to impart such movements to lures and baits of differing weights, sizes, buoyancies and physical structures. The first control is a variable rheostat which varies the angular velocity of the striker arm and thus varies the rate at which the striker arm contacts the length of fishing line positioned in the path of the striker arm.

Abstract: An apparatus for cutting limp sheet material with a rigid, cantilevered blade that is reciprocated as it advances along a cutting path through sheet material employs a load sensor to measure lateral loads applied to the blade by the sheet material during cutting. A load signal from the sensor is applied to the blade controls through a variable gain feedback circuit and causes the blade to be oriented slightly toward the side of the cutting path from which an unbalanced load is applied. The adjustment of the gain in the feedback network is made by means of speed sensors which measure the rate at which the cutting blade advances through the sheet material and adjust the feedback gain in inverse relationship.
