摘要： A linkage couples a pair of rotatable shafts so that the rotation of one the shafts causes rotation of the other said shaft about the some axis. The linkage includes a pair of thin flexure strips disposed in parallel between the pair of parallel rotatable shafts One end of the pair of flexure strips is coupled to one of the rotatable shafts and the other end of the pair of flexure strips is coupled to the other rotatable shaft. The pair of thin flexure strips is coupled to the shafts so that the rotation of one of the shafts will cause the flexure strips to rotate the other of the shafts. The rotatable shafts rotate around parallel axes. The flexure strips flex and bend together as the rotatable shafts rotate. The rotational motion transmitted by the flexure strips has the same axis as the rotation axis of the shafts.

摘要： A method and system provide for generating a predetermined feed spacing between a first document and a second document. The method includes the steps of determining an adjustment time period, and reducing a feed wheel speed to an adjustment speed. The feed wheel transports the documents between a document stack and a transport wheel. The method further provides for increasing the feed wheel speed after the adjustment time period has expired such that the trailing edge of the first document and the leading edge of the second document have the predetermined feed spacing. Determining the adjustment time period in conjunction with variable control of the feed wheel provides and enhanced approach to feed spacing unachievable through conventional approaches.

摘要： A method of detecting a document in a system for feeding and transporting documents includes detecting an acceleration of an accelerator idler indicating when the document trailing edge exits a feeder and a separator. The system includes a feeder stage including the feeder and the separator for receiving a document therebetween and gripping the document with a first grip, and a transport stage downstream of the feeder stage. The transport stage includes an accelerator driver and the accelerator idler for receiving the document therebetween and gripping the document with a second grip that is less than the first grip. When the document is simultaneously gripped by the feeder and separator and gripped by the accelerator driver and accelerator idler, the document slips at the accelerator driver until the document trailing edge exits the feeder and separator. The acceleration of the accelerator idler is detected to indicate when the document trailing edge exits the feeder and separator.

摘要： A document jogger jogs unit records such as checks and like value documents. The jogger has a bin for receiving the documents, and a vibrator coupled to the bin to vibrate it. A liner is adapted to be removably attached to the bin. The liner has an impact absorbing flexible material attached to the liner to absorb the shock of the documents as the bin is vibrated. A thin abrasion resistant, low friction layer covers the flexible material to prevent documents from damaging the flexible material and allows the documents to slide easily. The thin abrasion resistant, low friction layer is also soft enough to permit the flexible material to absorb the shock of said documents.

摘要： A document feeder includes a nudger located at a first side of a document stack. The nudger applies a nudger force to the first side of the document stack. An adjustable hopper positions the document stack next to the nudger. The adjustable hopper has a hopper floor that is an inclined plane supporting a flag. The flag adjustably rests against a side of the document stack opposite the nudger and applies a variable flag force to the document stack. The flag force changes according to the incline angle of the hopper floor. The flag has a weight, and as the incline of the hopper floor increases, the flag applies an increasing force caused by the weight to the document stack. The flag force is transmitted through the document stack. The document stack applies a force to the nudger and the nudger applies a reactionary force normal to the nudger. A feedback control is coupled between the nudger and adjustable hopper so that the nudger force can be changed by adjusting the incline of the hopper floor.

摘要： A circuit for controlling a servomotor while minimizing a steady-state velocity error being associated with the servomotor. A velocity transducer is coupled to the servomotor to provide a first signal representing an angular velocity of a servomotor shaft. A comparator receives as input the first signal and a second signal representing a desired angular velocity of the servomotor shaft. The comparator produces a comparator output signal representing the steady-state velocity error as defined by a difference between the angular velocity of a servomotor shaft and the desired angular velocity of the servomotor shaft. Means are provided for deriving a value of a current flowing through the servomotor and for producing a third signal representing that current. The third signal represents a frictional torque applied to the servomotor shaft. An adder receives as input the comparator output signal and the third signal. The adder produces an adder output signal representing a correction to the angular velocity of the servomotor shaft that compensates both for the frictional torque applied to the servomotor shaft and for the steady-state velocity error. Means are provided for amplifying the adder output signal to provide an amplified current and for driving the amplified current to the servomotor to effect the correction to the angular velocity of the servomotor shaft, thereby minimizing the steady-state velocity error.
