Abstract: In embodiments of a system for attracting and catching fish, a motor that's operationally coupled to a fishing reel is operated according to a predetermined motion profile in order to impart detailed and lifelike motion to a bait.

Abstract: In embodiments of translucent object presence and condition detection based on detected light intensity, a light is emitted and directed at a first edge of a translucent object along its thickness to pass through the translucent object, such as a lens. An intensity of the light is detected proximate an opposing, second edge of the translucent object. A presence and/or a condition of the translucent object can then be determined based on the detected intensity of the light that passes through the translucent object, where the detected intensity of the light that passes through the translucent object is relative and indicates one of: the presence of the translucent object based on a lower intensity of the light, or the translucent object is not present based on a higher intensity of the light.

Abstract: In embodiments of object presence and condition detection, a light is emitted that is directed at a first edge of a translucent object to pass through the translucent object, such as a lens. An intensity of the light is detected proximate an opposing, second edge of the translucent object. A presence and/or a condition of the translucent object can then be determined based on the detected intensity of the light that passes through the object. The translucent object can be implemented as a multi-lens array, and a laser light is directed through optic surfaces of the multi-lens array with a laser. The presence and the condition of the multi-lens array can be continuously determined as a safety compliance of the laser light being directed through the multi-lens array.

Abstract: A disk drive includes a disk drive base, a disk, an actuator arm actuatable over the disk, and a motor. The motor is operable to rotate the disk, and is coupled to the disk drive base. During operation of the disk drive, the motor emits vibrations at a source vibration frequency. A vibration absorber is coupled to the disk drive base, the vibration absorber including a cantilever beam having a fixed end and a free end.

Abstract: A method to assemble a disk drive having a spindle that includes a hub. At least one disk is placed on the hub. A clamp is fastened to the hub by a plurality of threaded fasteners. Each of the plurality of threaded fasteners is initially tightened. After initial tightening, an initial couple imbalance of the spindle is determined. After the initial couple imbalance is determined, a first selected threaded fastener of the plurality of threaded fasteners is selected and rotated by a first amount of rotation that is significantly different from a second amount of rotation of a second selected threaded fastener of the plurality of threaded fasteners. The selection and rotation of the first selected threaded fastener of the plurality of fasteners is determined based on the initial couple imbalance of the spindle.
