This invention discloses a 3-D Phenomenoscope through which any 2-dimensional motion picture with passages of horizontal screen movement can be viewed with a 3-dimensional visual effect. The 3-dimensional visual effect is produced by the 3-D Phenomenoscope regardless of whether the motion picture was shot on regular or digital film; regardless of whether the presentation media is film, digital film, VCR tape, or DVD, and; regardless of whether the motion picture is viewed in the movie theater, home TV, Cable TV, or on a PC monitor. No special processing during production or showing of a motion picture is required to achieve the visual effect of the 3-D Phenomenoscope—so no new constraints are placed on the owner, producer, distributor, or projectionist in creating, distributing or displaying motion pictures. The 3-D Phenomenoscope are completely self-contained computer-actuated battery-powered spectacles or glasses that a viewer wears when watching a motion picture. When the 3-D Phenomenoscope glasses are activated the viewer will see lateral motion in a motion picture in 3-dimensions. When the 3-D Phenomenoscope is not activated or the glasses are turned off, or if the viewer is not wearing the 3-D Phenomenoscope glasses, then the viewer will see the motion picture unchanged and without any special effects. The preferred embodiment of the invention presents a method and system for a 3-D Phenomenoscope to view 3-dimensional special effects in motion pictures, and disclose a system by which ordinary 2-dimensional motion pictures can be viewed as a 3-dimensionsal experience. The 3-D Phenomenoscope achieves this by taking advantage of the well-known Pulfrich effect, by which passages of lateral motion of an ordinary motion picture will appear to the viewer in 3-Dimensions if the motion picture is viewed through right and left lenses that are configured with a clear lens and a light-reducing or darker lens. Ordinary eyeglasses are configured with: (a) Right and left lenses for which the degree of clarity or darkening of the lens can be individually controlled (b) Digital photo sensors (a digital camera) that can capture the viewed motion picture as successive images and convert the captured frames to digital images for processing (c) Computer processor to process the successive images and identify lateral motion synchronization events, and (d) Ability to provide individual control for the light-reduction or darkening of the right or left lens based on the identified synchronization events. In this way, the 3-D Phenomenoscope provides a fully self-contained apparatus that allow any motion picture to be viewed with the visual effect of 3-dimensions.

A drive arrangement for split sickle bar sections of a harvester having a long cutter bar such as a combine, swather, mower-conditioner or the like utilizes separate drives for each sickle bar section, and provides for synchronizing the movement of the sickle bar sections so that they reach the respective ends of the reciprocating path simultaneously. In one form series connected first and second hydraulic motors are used, and the first motor in the series connection is reduced in speed from that which would be obtained from the full flow of a pump, by passing a portion of the pump fluid flow to a flow line leading to the second motor, a bleed valve bleeds off a portion of the flow in the flow line to regulate the second motor speed and position to match the speed and position of the first motor in response to signals indicating the position of the sickle bar sections. The sickle bar sections are thus synchronized.

A method for dynamically determining a motion control profile used in controlling motion of an axis of an overhead transport motor so as to be synchronized to the motion of a collating transport motor of an insertion engine used to insert a collation into an envelope when the collating transport motor causes a collating pusher to handoff the collation to an overhead pusher being driven by the overhead transport motor. The motion profile consists of a finite number of segments and repeats after the finite number of segments, the finite number of segments constituting a cycle. The method includes the steps of: electronically gearing the overhead transport motor to the collating transport motor from the beginning of a cycle until handoff; based on position information provided by a sensor, determining whether the collating transport is decelerating between handoff and insertion; and using either forward integration or electronic gearing of the overhead transport motor to the collating transport motor up until the collating transport motor is first determined to be decelerating between handoff and insertion, and using forward integration when the collating transport motor is first determined to be decelerating between handoff and insertion and continuing the forward integration until insertion. In some applications, the forward integration is used when the collating transport motor is first determined to be decelerating between handoff and insertion and continuing the forward integration until the end of the cycle.
